技术领域technical field
本实用新型涉及一种室内空气细颗粒物分级净化装置，属于空气净化设备技术领域。The utility model relates to a classifying and purifying device for fine particles in indoor air, which belongs to the technical field of air purifying equipment.
背景技术Background technique
近年来，由于灰霾天气的影响，细颗粒物(PM2.5，即空气动力学当量直径小于或等于2.5微米的颗粒物)成为影响空气质量的首要污染物；室内空气中PM2.5的浓度也相应升高，对居住空间的空气质量改善的要求在提高，因而针对PM2.5去除的空气净化器成为室内常见环保产品。In recent years, due to the influence of haze weather, fine particulate matter (PM2.5, that is, particulate matter with an aerodynamic equivalent diameter less than or equal to 2.5 microns) has become the primary pollutant affecting air quality; the concentration of PM2.5 in indoor air is also corresponding The demand for air quality improvement in living space is increasing, so air purifiers for PM2.5 removal have become common indoor environmental protection products.
目前针对室内PM2.5浓度的控制，传统空气净化器采用的原理方法多为过滤、吸附。该方法通过电动风机引起气流，使空气通过单层或多层具有致密网孔结构的平面滤网，从而在空气流通的情况下滞留或吸附颗粒物从而降低PM2.5浓度。但该方法存在以下问题：空气净化器长期运转后，滤网上颗粒物积累变厚，滤网网孔渐渐被颗粒物填充堵塞，影响进风从而影响净化效率；同时颗粒物容易从滤网上脱落重新释放到室内空气中，造成二次污染，不能达到对净化空气中颗粒物的效果。另外，传统空气净化器采用的原理还有静电除尘，该方法基于高压电场会产生臭氧，对人体也有危害。At present, for the control of indoor PM2.5 concentration, the principles and methods adopted by traditional air purifiers are mostly filtration and adsorption. In this method, an electric fan is used to induce air flow, so that the air passes through a single-layer or multi-layer flat filter screen with a dense mesh structure, thereby retaining or adsorbing particulate matter under the condition of air circulation to reduce the PM2.5 concentration. However, this method has the following problems: after long-term operation of the air purifier, the particulate matter on the filter becomes thicker, and the filter mesh is gradually filled and blocked by particulate matter, which affects the air intake and thus affects the purification efficiency; at the same time, the particulate matter is easy to fall off the filter and be released into the room In the air, secondary pollution is caused, and the effect of purifying particulate matter in the air cannot be achieved. In addition, the principle adopted by traditional air purifiers is electrostatic dust removal. This method is based on high-voltage electric fields that will generate ozone, which is also harmful to the human body.

Of course, the number of purification layers is not limited to three layers. The purification layer includes a deflector 3 and a collection plate 4. The deflector 3 is located above the collection plate 4. The end of the collection plate 4 is in contact with the shell. There are gaps between the inner walls of the body 1 .
导流板3和捕集板4相互平行。The guide plate 3 and the collecting plate 4 are parallel to each other.
捕集板4通过连接件5设置于壳体内。The collecting plate 4 is arranged in the casing through the connecting piece 5 .

导流板3和捕集板4均可拆卸地与壳体1连接，方便进行捕集板的清洗或粘性涂层的更换。Both the deflector plate 3 and the collecting plate 4 are detachably connected to the housing 1, which facilitates cleaning of the collecting plate or replacement of the viscous coating.
导流板3上设有若干导流孔。The deflector 3 is provided with several deflector holes.
相邻两个净化层之间的距离均相等。The distances between two adjacent purification layers are equal.
相对上层的导流板3上的导流孔的孔径大于相对下层的导流板3上的导流孔的孔径。The apertures of the guide holes on the upper deflector 3 are larger than those on the lower deflector 3 .
进风口处铺设有滤网2，所述出风口连接有电动风机6。A filter screen 2 is laid at the air inlet, and an electric fan 6 is connected to the air outlet.
本实用新型的工作原理为：为了方便说明，以从上到下的顺序，分别对各净化层中的导流板和捕集板进行分级命名，如最上层净化层的导流板为第一级导流板，中间层净化层的导流板为第二级导流板，最下层净化层的导流板为第三级导流板，同理，捕集板也分为第一级捕集板、第二级捕集板和第三级捕集板。The working principle of the utility model is as follows: for the convenience of explanation, the deflectors and collecting plates in each purification layer are graded and named in order from top to bottom, such as the deflector of the uppermost purification layer is the first level deflector, the deflector in the middle purification layer is the second-level deflector, and the deflector in the bottom purification layer is the third-level deflector. Similarly, the collection plate is also divided into the first-level collection Collecting plate, secondary collecting plate and tertiary collecting plate.
未净化的空气从进风口经过第一级导流板的导流孔后，由于颗粒粒径大小不同而具有不同的动量，较大的颗粒由于惯性阻留在第一级捕集板并粘附其上；而较小的粉尘颗粒则可以绕过第一级捕集板从未阻挡处流向第二级导流板的导流孔，继而较大颗粒阻留在第二级捕集板并粘附其上；第三级净化亦如此进行。After the unpurified air passes through the guide holes of the first-stage deflector from the air inlet, it has different momentum due to the different particle sizes. Larger particles are trapped in the first-stage collector plate due to inertia and adhere to it. while the smaller dust particles can bypass the unobstructed position of the first-stage collecting plate and flow to the guide hole of the second-stage deflecting plate, and then the larger particles are blocked in the second-stage collecting plate and stick to it. Attached to it; the third stage of purification is also carried out in the same way.
使用时，开启电动风机后，空气中的颗粒物从进风口进入本净化装置，过滤网初步捕集了大于100μm的颗粒物。过滤网下面是三级净化层，通过过滤网之后的颗粒物先通过第一级导流板，不同粒径的颗粒物通过导流孔后具有不同的动量，大于10μm的颗粒物会撞击到第一级捕集板上被吸附，而10μm以下的颗粒物会被气流带动，从第一级捕集板和壳体之间的空隙中带出，到达第二级导流板。第二级导流板上也均匀分布着多个孔径相同的导流孔，但孔径小于第一级导流板的孔径，因而通过第二级导流孔的颗粒物通过导流孔后又具有不同的动量，其中大于2.5μm的颗粒物会撞击到第二级捕集板上被吸附，而2.5μm以下的颗粒物会被气流带动，从第二级捕集板和壳体之间的空隙中带出，到达第三级导流板。通过第三级导流板后，2.5μm以下的颗粒物会被捕集吸附到第三级捕集板上面。When in use, after the electric fan is turned on, the particulate matter in the air enters the purification device from the air inlet, and the filter screen initially captures the particulate matter larger than 100 μm. Below the filter is a three-stage purification layer. Particles passing through the filter first pass through the first-stage deflector. Particles with different particle sizes have different momentums after passing through the deflector holes. Particles larger than 10 μm will hit the first-stage trap. The collecting plate is adsorbed, and the particles below 10 μm will be driven by the airflow, and will be taken out from the gap between the first-stage collecting plate and the shell, and reach the second-stage deflector. There are also multiple diversion holes with the same aperture evenly distributed on the second-stage deflector, but the aperture is smaller than that of the first-stage deflector, so the particles passing through the second-stage deflector have different characteristics after passing through the diversion hole. Momentum, in which particles larger than 2.5 μm will hit the second-stage collector plate and be adsorbed, while particles below 2.5 μm will be driven by the airflow and taken out from the gap between the second-stage collector plate and the housing , reaching the third-stage deflector. After passing through the third-stage deflector, particles below 2.5 μm will be trapped and adsorbed on the third-stage trapping plate.
因此，本实用新型的有益效果为：Therefore, the beneficial effects of the utility model are:
1、颗粒物的捕集过程稳定有效，长期运行也不影响进风系统；1. The capture process of particulate matter is stable and effective, and the long-term operation will not affect the air intake system;
2、被捕集的颗粒物组分稳定，不会逸散，在定期更换粘性涂层的情况下，可以避免二次污染；2. The captured particle components are stable and will not escape. In the case of regular replacement of the viscous coating, secondary pollution can be avoided;
3、经过三级净化能截留掉空气中小于2.5μm的污染物。3. After three-stage purification, it can intercept pollutants smaller than 2.5 μm in the air.
