Exemplarily, the support unit 1 may be a support plate or a support frame.
上述微藻收集面2可以相对于微藻具有一定的可附着性，即微藻收集面2具有一定的粗糙度或孔隙度，以使微藻能够附着在该微藻收集面2上，微藻附着在该微藻收集面2后，微藻不会流动，且微藻收集面2不会对微藻造成损伤。本发明实施不对微藻收集面2的粗糙度、孔隙度、材质和厚度中的任何一项作限定，只要微藻能够附着在微藻收集面2上即可。具体地，微藻收集面2的具体实现形式可以有多种，本领域技术人员可以根据实际需要进行选择。示例性地，微藻收集面2可以为具有磨砂面的金属板；或者，微藻收集面2可以为具有磨砂面的塑料板；或者，如图2所示，微藻收集面2为棉绒布21，在这种情况下，微藻收集装置经过一段时间使用后，只需要更换或者清洗棉绒布21即可，操作方便且成本低。进一步地，如图2所示，棉绒布21可以铺设于底板11上，以使棉绒布21的整个面均可以用于收集微藻，有利于提高收集微藻的效率。因此，本发明实施例中优选，微藻收集面2为棉绒布21，且该棉绒布21铺设于底板11上。示例性地，上述底板11可以为硬质塑料板。The above-mentioned microalgae collecting surface 2 may have a certain degree of attachability relative to the microalgae, that is, the microalgae collecting surface 2 has a certain roughness or porosity, so that the microalgae can be attached to the microalgae collecting surface 2, and the microalgae After being attached to the microalgae collecting surface 2, the microalgae will not flow, and the microalgae collecting surface 2 will not cause damage to the microalgae. The implementation of the present invention does not limit any of the roughness, porosity, material and thickness of the microalgae collection surface 2, as long as the microalgae can attach to the microalgae collection surface 2. Specifically, there may be various specific implementation forms of the microalgae collection surface 2, and those skilled in the art may choose according to actual needs. Exemplarily, the microalgae collection surface 2 can be a metal plate with a frosted surface; or, the microalgae collection surface 2 can be a plastic plate with a frosted surface; or, as shown in Figure 2, the microalgae collection surface 2 is a cotton flannelette 21. In this case, after the microalgae collection device has been used for a period of time, it only needs to replace or clean the cotton flannelette 21, which is easy to operate and low in cost. Further, as shown in FIG. 2 , the lint cloth 21 can be laid on the bottom plate 11 so that the entire surface of the lint cloth 21 can be used to collect microalgae, which is beneficial to improve the efficiency of collecting microalgae. Therefore, in the embodiment of the present invention, preferably, the microalgae collecting surface 2 is cotton flannelette 21 , and the cotton flannelette 21 is laid on the bottom plate 11 . Exemplarily, the above-mentioned base plate 11 may be a hard plastic plate.
由于本发明实施例所提供的微藻收集装置具有如上所述的结构，从而使得在使用该微藻收集装置收集微藻的过程中，微藻养殖液中的微藻能够附着在微藻收集面2上，进而能够实现藻水分离，达到收集微藻的目的，因此，无需使用造价昂贵的气浮分离设备即可收集微藻，从而降低了收集微藻的成本。Since the microalgae collection device provided by the embodiment of the present invention has the above-mentioned structure, the microalgae in the microalgae culture solution can adhere to the microalgae collection surface during the process of using the microalgae collection device to collect microalgae 2, the separation of algae and water can be achieved, and the purpose of collecting microalgae can be achieved. Therefore, microalgae can be collected without using expensive air flotation separation equipment, thereby reducing the cost of collecting microalgae.
本发明实施例所提供的微藻收集装置除了具有以上有益效果外，还具有如下几方面的有益效果：第一方面，当采用现有技术中的离心分离法收集微藻时，需要使用大功率的离心设备以将微藻养殖液中的液体除去，其中，大功率的离心设备为高耗能的设备，而在使用本发明实施例所提供的微藻收集装置收集微藻的过程中，不需要使用大功率的离心设备，有助于降低收集微藻所需的能耗；第二方面，当采用现有技术中的膜过滤法收集微藻时，由于微藻会粘附在过滤膜上，导致过滤膜中的过滤孔被堵塞，从而使得藻水分离不能顺利进行，而在使用本发明实施例所提供的微藻收集装置收集微藻的过程中，不需要使用过滤膜来收集微藻，从而使得藻水分离能够顺利进行；第三方面，当采用现有技术中的连续气浮分离法收集微藻时，为使微藻适当团聚以加快收集微藻的速度，通常会向微藻养殖液中加入絮凝剂及用于调节微藻养殖液的PH值的化学试剂，从而会污染环境水体，而在使用本发明实施例所提供的微藻收集装置收集微藻的过程中，不需要向微藻养殖液中加入絮凝剂及用于调节微藻养殖液的PH值的化学试剂，有助于保护环境水体。In addition to the above beneficial effects, the microalgae collection device provided by the embodiments of the present invention also has the following beneficial effects: First, when using the centrifugal separation method in the prior art to collect microalgae, it is necessary to use high power centrifugal equipment to remove the liquid in the microalgae culture solution, wherein, high-power centrifugal equipment is a high-energy-consuming equipment, and in the process of collecting microalgae using the microalgae collection device provided by the embodiment of the present invention, no It is necessary to use high-power centrifugal equipment, which helps to reduce the energy consumption required for collecting microalgae; secondly, when adopting the membrane filtration method in the prior art to collect microalgae, since the microalgae will adhere to the filter membrane , causing the filter holes in the filter membrane to be blocked, so that the separation of algae water cannot be carried out smoothly, and in the process of collecting microalgae using the microalgae collection device provided by the embodiment of the present invention, there is no need to use a filter membrane to collect microalgae , so that the separation of algae water can be carried out smoothly; the third aspect, when using the continuous air flotation separation method in the prior art to collect microalgae, in order to make the microalgae properly aggregate to speed up the speed of collecting microalgae, usually the microalgae Adding flocculants and chemical reagents for adjusting the pH value of the microalgae culture solution in the culture solution will pollute the environmental water body, but in the process of collecting microalgae using the microalgae collection device provided by the embodiment of the present invention, no need Adding flocculants and chemical reagents for adjusting the pH value of the microalgae culture solution to the microalgae culture solution helps to protect the environmental water body.
此外，还值得一提的是，微藻自身具有许多独特的性质，使其能够进一步较牢固地吸附在微藻收集面2上。例如，丝状的微藻和带有鞭毛的微藻易于嵌入或钩挂在具有孔隙或者多毛结构的微藻收集面2上；能够在表面分泌粘性分泌物的微藻，其能够利用粘性分泌物吸附微藻养殖液中的微藻，从而即使微藻收集面2完全被微藻所覆盖，附着在微藻收集面2上的微藻仍然能够利用其表面的粘性分泌物吸附微藻养殖液中的微藻，从而使微藻收集面2能够继续用于收集微藻；类似地，表面带有电荷的微藻，其能够利用电荷的静电吸引力吸附微藻养殖液中的微藻，从而即使微藻收集面2完全被微藻所覆盖，附着在微藻收集面2上的微藻仍然能够利用其表面的电荷吸附微藻养殖液中的微藻，从而使微藻收集面2能够继续用于收集微藻。由上所述可知，微藻的这些特性可以使微藻紧密且牢固地吸附在微藻收集面2上，从而能够进一步抵御微藻养殖液的冲刷。In addition, it is also worth mentioning that the microalgae itself has many unique properties, which enable it to be further firmly adsorbed on the microalgae collecting surface 2 . For example, filamentous microalgae and microalgae with flagella are easy to embed or hook on the microalgae collection surface 2 with pores or hairy structures; microalgae that can secrete viscous secretions on the surface can utilize viscous secretions Adsorb the microalgae in the microalgae culture solution, so that even if the microalgae collection surface 2 is completely covered by the microalgae, the microalgae attached to the microalgae collection surface 2 can still use the sticky secretions on its surface to absorb the microalgae in the microalgae culture solution microalgae, so that the microalgae collection surface 2 can continue to be used to collect microalgae; similarly, the microalgae with charge on the surface can use the electrostatic attraction of the charge to adsorb the microalgae in the microalgae culture solution, so that even The microalgae collection surface 2 is completely covered by microalgae, and the microalgae attached to the microalgae collection surface 2 can still use the charge on its surface to adsorb the microalgae in the microalgae culture solution, so that the microalgae collection surface 2 can continue to be used. for collecting microalgae. From the above, it can be seen that these characteristics of microalgae can make the microalgae tightly and firmly adsorb on the microalgae collecting surface 2, so as to further resist the scouring of the microalgae culture solution.
使用上述微藻收集装置收集微藻的过程中，使微藻养殖液与微藻收集面2接触，以收集微藻的方式可以有多种，本领域技术人员可以根据实际需要进行合理选择。示例性地，本发明实施例中例举两种具有不同结构的微藻收集装置，该两种微藻收集装置分别通过不同方式使微藻养殖液与微藻收集面2接触：In the process of collecting microalgae using the above-mentioned microalgae collecting device, there are many ways to collect microalgae by contacting the microalgae culture solution with the microalgae collecting surface 2 , and those skilled in the art can make reasonable choices according to actual needs. Exemplarily, in the embodiment of the present invention, two types of microalgae collection devices with different structures are exemplified, and the two types of microalgae collection devices respectively contact the microalgae culture liquid with the microalgae collection surface 2 in different ways:
第一种微藻收集装置，如图3所示，微藻收集装置除了包括支撑单元1和微藻收集面2外，还包括驱动机构3，其中，驱动机构3与支撑单元1连接，用于带动支撑单元1上的微藻收集面2在微藻养殖液4中移动，进而使得微藻养殖液4与微藻收集面2接触。示例性地，使用上述微藻收集装置收集微藻的过程如下：首先通过驱动机构3使微藻收集面2向下移动，使微藻收集面2浸没于微藻养殖液4中，再通过驱动机构3使微藻收集面2向上移动，在微藻收集面2向上移动的过程中，微藻养殖液4中的液体会流下，而微藻养殖液4中的微藻则附着在微藻收集面2上，进而实现了藻水分离，达到收集微藻的目的。此微藻收集装置的结构较简单，成本较低。The first microalgae collection device, as shown in Figure 3, the microalgae collection device also includes a drive mechanism 3 in addition to the support unit 1 and the microalgae collection surface 2, wherein the drive mechanism 3 is connected to the support unit 1 for The microalgae collecting surface 2 on the supporting unit 1 is driven to move in the microalgae culture liquid 4 , and then the microalgae culture liquid 4 is in contact with the microalgae collecting surface 2 . Exemplarily, the process of collecting microalgae using the above-mentioned microalgae collection device is as follows: first, the microalgae collection surface 2 is moved downward through the driving mechanism 3, so that the microalgae collection surface 2 is immersed in the microalgae culture solution 4, and then the Mechanism 3 moves the microalgae collection surface 2 upwards, and during the upward movement of the microalgae collection surface 2, the liquid in the microalgae culture solution 4 will flow down, and the microalgae in the microalgae culture solution 4 will adhere to the microalgae collection surface. On the surface 2, the separation of algae and water is realized, and the purpose of collecting microalgae is achieved. The structure of the microalgae collecting device is relatively simple, and the cost is low.
在微藻附着在微藻收集面2上之后，可以先将附着在微藻收集面2上的微藻刮下来，使微藻收集面2暴露，再重新将微藻收集面2浸没于微藻养殖液4中，然后重复上述过程。另外，由以上所述可知，微藻的表面会分泌粘性分泌物，从而使得微藻能够利用其表面的粘性分泌物吸附微藻养殖液4中的微藻，继续收集微藻，因此，在微藻附着在微藻收集面2上之后，也可以直接将微藻收集面2再次浸没于微藻养殖液4中，重复上述过程，直到微藻收集面2上附着的微藻的量无明显增加为止，再将附着在微藻收集面2上的微藻刮下来。After the microalgae is attached to the microalgae collection surface 2, the microalgae attached to the microalgae collection surface 2 can be scraped off to expose the microalgae collection surface 2, and then the microalgae collection surface 2 is submerged in the microalgae again. culture solution 4, and then repeat the above process. In addition, as can be seen from the above, the surface of microalgae can secrete viscous secretions, so that microalgae can utilize the viscous secretions on its surface to absorb the microalgae in the microalgae culture solution 4 and continue to collect microalgae. After the algae are attached to the microalgae collection surface 2, the microalgae collection surface 2 can also be directly submerged in the microalgae culture solution 4 again, and the above process is repeated until the amount of microalgae attached to the microalgae collection surface 2 does not increase significantly. Till then, the microalgae attached to the microalgae collection surface 2 is scraped off.
可选地，该微藻收集装置还可以包括刮刀，该刮刀用于将微藻从微藻收集面2上刮下来。示例性地，该刮刀可以为玻璃板，该玻璃板的长可以为20厘米，宽可以为10厘米，厚度可以为0.5厘米。Optionally, the microalgae collecting device may also include a scraper, which is used to scrape the microalgae off the microalgae collecting surface 2 . Exemplarily, the scraper can be a glass plate, and the glass plate can be 20 cm long, 10 cm wide, and 0.5 cm thick.
第二种微藻收集装置，如图4所示(图中以箭头表示微藻养殖液4的流动方向)，微藻收集装置除了包括支撑单元1和微藻收集面2外，还包括喷洒机构5和泵6，其中，喷洒机构5设置于微藻收集面2上方，泵6的进液口浸没在微藻养殖液4中，泵6的出液口与喷洒机构5连通，喷洒机构5用于将微藻养殖液4喷洒至微藻收集面2上。可选地，上述泵6为潜水泵，潜水泵的出液口可以通过塑料管与喷洒机构5连通。示例性地，使用上述微藻收集装置收集微藻的过程如下：首先通过泵6将微藻养殖液4输送至喷洒机构5中，然后喷洒机构5将微藻养殖液4喷洒至微藻收集面2上，其中，微藻养殖液4中的液体能够从微藻收集面2流下，而微藻养殖液4中的微藻则能够附着在微藻收集面2上，进而实现藻水分离，达到收集微藻的目的。由于在上述过程中，可以通过喷洒机构5和泵6持续地将微藻养殖液4喷洒至微藻收集面2上，从而可以实现对微藻的连续收集，进而提高了收集微藻的效率。The second microalgae collection device, as shown in Figure 4 (the flow direction of the microalgae culture solution 4 is indicated by the arrow in the figure), the microalgae collection device also includes a spraying mechanism in addition to the support unit 1 and the microalgae collection surface 2 5 and a pump 6, wherein the spraying mechanism 5 is arranged above the microalgae collecting surface 2, the liquid inlet of the pump 6 is immersed in the microalgae culture liquid 4, and the liquid outlet of the pump 6 communicates with the spraying mechanism 5, and the spraying mechanism 5 uses Then spray the microalgae culture solution 4 onto the microalgae collection surface 2 . Optionally, the above-mentioned pump 6 is a submersible pump, and the liquid outlet of the submersible pump can communicate with the spraying mechanism 5 through a plastic pipe. Exemplarily, the process of collecting microalgae using the above-mentioned microalgae collection device is as follows: first, the microalgae culture solution 4 is transported to the spray mechanism 5 through the pump 6, and then the spray mechanism 5 sprays the microalgae culture solution 4 onto the microalgae collection surface 2, wherein the liquid in the microalgae culture solution 4 can flow down from the microalgae collection surface 2, and the microalgae in the microalgae culture solution 4 can attach to the microalgae collection surface 2, thereby realizing the separation of algae and water, achieving The purpose of collecting microalgae. Since in the above process, the microalgae culture liquid 4 can be continuously sprayed onto the microalgae collection surface 2 through the spraying mechanism 5 and the pump 6, so that the continuous collection of the microalgae can be realized, thereby improving the efficiency of collecting the microalgae.
在上述过程中，可以直到微藻收集面2上附着的微藻的量无明显增加时，将附着在微藻收集面2上的微藻刮下来。类似地，该微藻收集装置还可以包括刮刀，该刮刀用于将微藻从微藻收集面2上刮下来。示例性地，该刮刀可以为玻璃板，该玻璃板的长可以为20厘米，宽可以为10厘米，厚度可以为0.5厘米。During the above process, the microalgae attached to the microalgae collecting surface 2 can be scraped off until the amount of microalgae attached to the microalgae collecting surface 2 does not increase significantly. Similarly, the microalgae collection device may also include a scraper, which is used to scrape the microalgae off the microalgae collection surface 2 . Exemplarily, the scraper can be a glass plate, and the glass plate can be 20 cm long, 10 cm wide, and 0.5 cm thick.
具体地，喷洒机构5的具体实现方式可以有多种，本领域技术人员可以根据实际需要进行合理选择。示例性地，如图5所示(图中以箭头表示微藻养殖液4的流动方向)，喷洒机构5包括横跨在微藻收集面2上的出液管7，出液管7的一端密封，出液管7的另一端具有开口，出液管7的开口的一端与泵6的出液口连通，出液管7的管壁上设有多个喷洒孔8。微藻养殖液4通过泵6输送至出液管7的开口的一端，然后进入出液管7中，微藻养殖液4再通过喷洒口8喷洒至微藻收集面2上。示例性地，上述出液管7可以为有机塑料管或者钢管。Specifically, there may be various specific implementation manners of the spraying mechanism 5, and those skilled in the art may make reasonable choices according to actual needs. Exemplarily, as shown in Figure 5 (indicates the flow direction of microalgae culture liquid 4 with arrow among the figure), spray mechanism 5 comprises the liquid outlet pipe 7 that straddles on microalgae collection surface 2, one end of liquid outlet pipe 7 Sealing, the other end of the liquid outlet pipe 7 has an opening, one end of the opening of the liquid outlet pipe 7 communicates with the liquid outlet of the pump 6, and a plurality of spray holes 8 are arranged on the pipe wall of the liquid outlet pipe 7 . The microalgae culture solution 4 is transported to one end of the opening of the outlet pipe 7 by the pump 6, and then enters the outlet pipe 7, and the microalgae culture solution 4 is sprayed on the microalgae collection surface 2 through the spray port 8. Exemplarily, the liquid outlet pipe 7 may be an organic plastic pipe or a steel pipe.
优选地，多个喷洒孔8均匀分布在出液管7的管壁上，从而使得微藻养殖液4可以通过各个喷洒孔8均匀地喷洒至微藻收集面2上，进而使得整个微藻收集面2上均能够附着微藻，有利于提高收集微藻的效率。示例性地，各个喷洒孔8之间的距离可以为1厘米～2厘米。Preferably, a plurality of spray holes 8 are evenly distributed on the pipe wall of the liquid outlet pipe 7, so that the microalgae culture solution 4 can be evenly sprayed onto the microalgae collection surface 2 through each spray hole 8, and then the entire microalgae is collected. Microalgae can be attached to the surface 2, which is conducive to improving the efficiency of collecting microalgae. Exemplarily, the distance between each spray hole 8 may be 1 cm to 2 cm.
进一步地，使出液管7横跨在微藻收集面2上的方式可以有多种，本领域技术人员可以根据实际需要进行合理选择。示例性地，本发明实施例中的微藻收集装置还包括夹子，夹子将出液管7夹在微藻收集面2的顶端上，从而使得从出液管7流出的微藻养殖液4能够从微藻收集面2的顶端流下，进而能够流经整个微藻收集面2，以进一步提高收集微藻的效率。Further, there are various ways to make the liquid outlet pipe 7 straddle the microalgae collecting surface 2, and those skilled in the art can make a reasonable choice according to actual needs. Exemplarily, the microalgae collecting device in the embodiment of the present invention also includes a clip, and the clip clamps the outlet pipe 7 on the top of the microalgae collection surface 2, so that the microalgae culture solution 4 flowing out from the outlet pipe 7 can be It flows down from the top of the microalgae collection surface 2, and then can flow through the entire microalgae collection surface 2, so as to further improve the efficiency of collecting microalgae.
此外，本发明实施例中优选微藻收集面2倾斜设置，且微藻收集面2的底端位于微藻养殖液4中，此时，微藻养殖液4流经微藻收集面2后，流下的液体可以再次通过泵6输送至出液管7中，然后重新喷洒至微藻收集面2上，进而使得该微藻收集装置具有更高的收集微藻的效率。需要说明的是，在微藻收集面2使用过程中，微藻收集面2的两端中，距离地面较高的一端称为“微藻收集面2的顶端”，距离地面较低的一端称为“微藻收集面2的底端”。In addition, in the embodiment of the present invention, it is preferred that the microalgae collection surface 2 is arranged obliquely, and the bottom end of the microalgae collection surface 2 is located in the microalgae culture liquid 4. At this time, after the microalgae culture liquid 4 flows through the microalgae collection surface 2, The liquid that flows down can be delivered to the liquid outlet pipe 7 by the pump 6 again, and then sprayed onto the microalgae collecting surface 2 again, so that the microalgae collecting device has a higher efficiency of collecting microalgae. It should be noted that during the use of the microalgae collection surface 2, among the two ends of the microalgae collection surface 2, the end that is higher from the ground is called "the top of the microalgae collection surface 2", and the end that is lower from the ground is called "the top of the microalgae collection surface 2". It is "the bottom end of the microalgae collection surface 2".
进一步地，本申请的发明人发现，若微藻收集面2的倾斜角度过大，微藻养殖液4在微藻收集面2上的流动速度过大，则会导致微藻容易被液体冲下，而难以附着在微藻收集面2上；若微藻收集面2的倾斜角度过小，微藻养殖液4在微藻收集面2上的流动速度过慢，导致收集微藻的效率过低。因此，微藻收集面2的倾斜角度的合理选择是十分重要的。优选地，微藻收集面2的倾斜角度为10度～30度。Further, the inventors of the present application have found that if the inclination angle of the microalgae collection surface 2 is too large, the flow velocity of the microalgae culture solution 4 on the microalgae collection surface 2 is too high, which will cause the microalgae to be easily washed down by the liquid. , and it is difficult to attach to the microalgae collection surface 2; if the inclination angle of the microalgae collection surface 2 is too small, the flow velocity of the microalgae culture solution 4 on the microalgae collection surface 2 is too slow, resulting in low efficiency of collecting microalgae . Therefore, the reasonable selection of the inclination angle of the microalgae collecting surface 2 is very important. Preferably, the inclination angle of the microalgae collecting surface 2 is 10°-30°.
