技术领域Technical field
本发明涉及储罐技术领域，特别是涉及一种储罐及其保护装置。The present invention relates to the technical field of storage tanks, and in particular to a storage tank and its protection device.
背景技术Background technique
储罐是一种工业上的存储设备，是各行各业中不可缺少的基础设备。Storage tank is an industrial storage equipment and an indispensable basic equipment in all walks of life.
储罐内部是一个相对密闭的空间，在物料进出储罐时储罐内部的气体空间被压缩或扩大，因此，在物料进出储罐时需要对储罐进行补气与排气，以避免储罐内部形成负压将储罐吸扁或形成正压撑破储罐。The inside of the storage tank is a relatively closed space. When materials enter and exit the storage tank, the gas space inside the storage tank is compressed or expanded. Therefore, the storage tank needs to be replenished and exhausted when materials enter and exit the storage tank to prevent the storage tank from collapsing. Negative pressure is formed inside to flatten the tank or positive pressure is formed to burst the tank.
现有技术中，一般通过呼吸阀或浮顶进行补气或排气。其中，采用在储罐顶部安装呼吸阀，在储罐内部形成正压时，将储罐内部气体向外界排出以进行排气，在储罐内部形成负压时，将外界空气吸入储罐内部以进行补气，虽然这种方式简单实用，但在排气时会造成储罐内部物料挥发，同时在补气时会吸入外界空气污染物料；此外，呼吸阀还可能被挥发后又重新结晶的物料堵塞导致储罐损坏。其中，采用浮顶时，虽然可以减少储罐内部物料挥发量且能够隔绝外界空气，避免储罐内部受到污染，但浮顶的结构复杂、造价高，且维修不便；此外，浮顶与储罐内壁间密封长期使用中存在泄露风险。In the prior art, air supply or exhaust is generally performed through a breathing valve or floating roof. Among them, a breathing valve is installed on the top of the storage tank. When a positive pressure is formed inside the tank, the gas inside the tank is discharged to the outside for exhaust. When a negative pressure is formed inside the tank, outside air is sucked into the tank. Although this method is simple and practical, it will cause the materials inside the tank to volatilize when exhausting, and at the same time, pollutants from the outside air will be inhaled during the air supply. In addition, the breathing valve may also be filled with materials that recrystallize after evaporation. Blockage causes damage to the tank. Among them, although the floating roof can reduce the volatilization of materials inside the storage tank and can isolate the outside air and avoid contamination inside the storage tank, the floating roof has a complex structure, high cost, and inconvenient maintenance; in addition, the floating roof and the storage tank There is a risk of leakage during long-term use of the seal between the inner walls.

如图1所示，本发明优选实施例的一种储罐保护装置，包括储气机构、补气阀3、供气管道2，以及单向阀4；储气机构用于存储惰性气体；所述储气机构能够通过所述供气管道2与所述储罐连通；补气阀3设于所述供气管道2上；所述储罐具有排气口，单向阀4具有用于与所述排气口连通并供储罐内部气体排出的单向通道；所述单向阀4能够在所述储罐内部压力大于第一预定值下开启，所述补气阀3能够在所述储罐内部的压力低于第二预定值下开启，所述第一预定值大于所述第二预定值。As shown in Figure 1, a storage tank protection device according to the preferred embodiment of the present invention includes a gas storage mechanism, a gas supply valve 3, a gas supply pipeline 2, and a one-way valve 4; the gas storage mechanism is used to store inert gas; so The gas storage mechanism can communicate with the storage tank through the gas supply pipe 2; the gas supply valve 3 is provided on the gas supply pipe 2; the storage tank has an exhaust port, and the one-way valve 4 has a The exhaust port is connected to a one-way channel for the gas inside the storage tank to be discharged; the one-way valve 4 can be opened when the internal pressure of the storage tank is greater than the first predetermined value, and the air supply valve 3 can be opened when the internal pressure of the storage tank is greater than the first predetermined value. The storage tank is opened when the pressure inside the tank is lower than a second predetermined value, and the first predetermined value is greater than the second predetermined value.
基于上述方案，当储罐内部压力升高至第一预定值以上时，单向阀4开启，储罐内部的气体通过排气口和单向阀4的单向通道流出储罐内部，降低储罐内部的压力，从而避免储罐内部压力过大撑破储罐，此时需要保持补气阀3关闭，当储罐内部压力降低至第二预定值以下时，补气阀3开启，储气机构内部存储的惰性气体通过供气管道2进入到储罐内部，提高储罐内部的压力，从而避免储罐内部的压力过小吸扁储罐，此时，需要保持单向阀4的关闭。Based on the above solution, when the internal pressure of the storage tank rises above the first predetermined value, the one-way valve 4 opens, and the gas inside the storage tank flows out of the storage tank through the exhaust port and the one-way channel of the one-way valve 4, reducing the storage capacity. The pressure inside the tank, so as to prevent the internal pressure of the storage tank from being too high to burst the storage tank. At this time, the gas supply valve 3 needs to be kept closed. When the internal pressure of the storage tank drops below the second predetermined value, the gas supply valve 3 is opened, and the gas storage The inert gas stored inside the mechanism enters the interior of the storage tank through the gas supply pipe 2, increasing the pressure inside the storage tank, thereby preventing the pressure inside the storage tank from being too low and flattening the storage tank. At this time, the one-way valve 4 needs to be kept closed.
基于上述方案，本发明相比于现有技术，具备如下有益效果：Based on the above solution, compared with the existing technology, the present invention has the following beneficial effects:
1、本发明无需使用浮顶，造价低廉，结构简单。1. The present invention does not require the use of floating roofs, has low cost and simple structure.
2、本发明在对储罐内部进行升压时，采用的是惰性气体，其对于储罐内部存储的物料和外界环境均是无害的，既不会污染储罐内部存储的物料，也不会对外界环境造成污染。2. When the present invention increases the pressure inside the storage tank, it uses inert gas, which is harmless to the materials stored inside the storage tank and the external environment. It will neither contaminate the materials stored inside the storage tank nor It will cause pollution to the external environment.
其中，为实现当储罐内部压力升高至第一预定值以上时单向阀4开启的方式有多种，如人工手动开启或选用电动阀体作为本方案的单向阀4。作为一种优选的实施方式，所述单向阀4的开启压力数值上等于第一预定值减去单向阀4后侧的环境压力值；由此，在储罐内部压力达到并超过第一预定值时，单向阀4开启并对储罐内部泄压，直至储罐内部压力重新回到第一预定值以下，此时，单向阀4的启停不需要人工控制。Among them, there are many ways to open the one-way valve 4 when the internal pressure of the storage tank rises above the first predetermined value, such as manual opening or using an electric valve body as the one-way valve 4 of this solution. As a preferred embodiment, the opening pressure of the one-way valve 4 is numerically equal to the first predetermined value minus the ambient pressure value on the rear side of the one-way valve 4; thus, the pressure inside the storage tank reaches and exceeds the first At the predetermined value, the one-way valve 4 opens and releases the pressure inside the storage tank until the internal pressure of the storage tank returns below the first predetermined value. At this time, the start and stop of the one-way valve 4 does not require manual control.
其中，同理，为实现当储罐内部压力降低至第二预定值以下时补气阀3开启的方式有多种；作为一种优选的实施方式，将补气阀3设置为具有开启压力的安全阀体结构，并将补气阀3的开启压力数值上设置为储气机构内部压力减去第二预定值，由此，在储罐内部的压力达到并低于第二预定值以下时，补气阀3开启并对储罐内部升压，直至储罐内部压力重新达到第二预定值以上，此时，补气阀3的启停无需人工控制。Among them, in the same way, there are many ways to open the air supply valve 3 when the internal pressure of the storage tank drops below the second predetermined value; as a preferred implementation, the air supply valve 3 is set to have an opening pressure. Safety valve body structure, and the opening pressure of the air supply valve 3 is numerically set to the internal pressure of the gas storage mechanism minus the second predetermined value. Therefore, when the pressure inside the storage tank reaches and falls below the second predetermined value, The gas supply valve 3 opens and increases the pressure inside the storage tank until the internal pressure of the storage tank reaches above the second predetermined value again. At this time, the start and stop of the gas supply valve 3 does not require manual control.

A predetermined value>a second predetermined value>the second value.
基于此实施方式，当储罐内部压力达到第一预定值以上，且单向阀4由于意外，如储罐内部挥发气体结晶堵塞单向阀4，无法开启时，储罐内部压力将继续上升至超过第一值，压力传感器8检测到储罐内部压力值大于第一值时，第一阀体6开启，通过第一阀体6排出储罐内部气体；而当储罐内部压力达到第二预定值以下，且补气阀3由于意外，如卡死，无法开启时，储罐内部压力将继续降低至低于第二值，压力传感器8检测到储罐内部压力小于第二值时，第一阀体6开启，通过第一阀体6向储罐内部供气。Based on this implementation, when the internal pressure of the storage tank reaches above the first predetermined value and the one-way valve 4 cannot be opened due to an accident, such as the volatile gas crystallization inside the storage tank blocking the one-way valve 4, the internal pressure of the storage tank will continue to rise to When the pressure sensor 8 detects that the internal pressure of the storage tank is greater than the first value, the first valve body 6 opens, and the gas inside the storage tank is discharged through the first valve body 6; and when the internal pressure of the storage tank reaches the second predetermined value, value is below the second value, and the air supply valve 3 cannot be opened due to an accident, such as being stuck, the internal pressure of the storage tank will continue to decrease below the second value. When the pressure sensor 8 detects that the internal pressure of the storage tank is less than the second value, the first The valve body 6 is opened, and air is supplied to the inside of the storage tank through the first valve body 6 .
