Contents of the invention

The purpose of the utility model is to provide an acid mist purification tower, which has the characteristics of small resistance, sufficient gas-liquid contact, excellent absorption efficiency, small footprint, compact structure, convenient operation and safe operation.

In order to achieve the above purpose, the utility model adopts the following technical solutions:

The acid mist purification tower includes a tower body in which a waste gas inlet is opened, and the top of the tower body is a gas outlet. The tower body is sequentially provided with a packing layer, a spray head, a swirl plate and a dehydration unit from bottom to top. layer. When the acid mist exhaust gas enters the tower body, it will not be evenly distributed to the entire cross section of the tower body. The packing layer helps to improve the absorption efficiency. In addition to making the exhaust gas in the spray area evenly distributed, it also makes the exhaust gas and the absorption liquid or washing liquid The liquid film area on the packing layer is fully contacted. After the waste gas enters the packing layer, the spray liquid is transported by the acid and alkali resistant ring water pump outside the tower to the nozzle of the spray head and sprayed into the waste gas, so that the absorption liquid or washing liquid It is evenly distributed in the purification tower and fully reacts with the exhaust gas. Under the action of the swirl plate, the treated exhaust gas makes the liquid in the air flow separate under the action of centrifugal force, removes the liquid components in the air flow, and passes through the action of the swirl plate. The air flow then flows through the dehydration layer, and the liquid droplets in the air flow remain in the dehydration layer due to inertia, and the solid pollutants in the liquid droplets are further removed, and then discharged into the atmosphere.

As an improvement of the acid mist purification tower of the present invention, the bottom plate of the tower body is provided with a liquid level indicator and a waste water outlet, through which the liquid level indicator can observe the amount of liquid in the liquid storage tank in the tower body. If the liquid in the tank does not meet the requirements for waste gas treatment, it can be discharged through the waste water outlet, and the relevant waste gas treatment liquid can be replaced in time.

As another improvement of the acid mist purification tower of the utility model, the tower body is made of glass fiber reinforced plastic material in sections.

As another improvement of the acid mist purification tower of the present invention, the surface of the tower body is provided with an anti-aging layer of gel coat resin. The gel coat resin has the characteristics of water resistance and aging resistance, which can prolong the service life of the purification tower.

As a further improvement of the acid mist purification tower of the utility model, the gel coat thickness of the anti-aging layer of the gel coat resin is not less than 0.5mm.

As a further improvement of the acid mist purification tower of the utility model, an inspection window is provided in the tower body, through which the processing conditions in the tower body can be observed at any time.

As a further improvement of the acid mist purification tower of the utility model, the packing layer is a curd packing layer, and the curd packing layer is used to increase the contact area between the waste gas and the waste gas, which is beneficial to the reaction between the spray liquid and the waste gas.

As a further improvement of the acid mist purification tower of the present utility model, two groups of packing layers and spray heads are alternately arranged to further enhance the purification effect of the purification tower.

As can be seen from the above, the utility model has the following beneficial effects compared with the prior art:

The acid mist purification tower of the utility model has the advantages of small resistance, sufficient gas-liquid contact, excellent absorption efficiency, compact structure, convenient operation and safe operation.

Detailed ways

The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent.

For those skilled in the art, it is understandable that some well-known structures and descriptions thereof may be omitted in the drawings.

The technical solutions in the utility model will be clearly and completely described below in conjunction with the accompanying drawings of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figure 1, it is a structural schematic diagram of a preferred embodiment of the utility model acid mist purification tower, which includes a tower body, and an exhaust gas inlet 1 is opened in the tower body, and the exhaust gas is sent to the exhaust gas inlet 1 by the centrifugal fan 2 Among them, the top of the tower body is the gas outlet 3, and the tower body is provided with packing layer 4, spray head 5, swirl plate 6 and dehydration layer 7 in sequence from bottom to top. The packing layer 4 adopts flower ball packing layer, and the tower The bottom of the body is a liquid storage tank 8, which is provided with a liquid level indicator 9 and a waste water discharge outlet 10, wherein, when the concentration of the exhaust gas is relatively high, the packing layer 4 and the sprinkler head 5 can alternately Set up as two groups.

In order to prolong the service life of this purification tower, the tower body is made of glass fiber reinforced plastic material in sections, and the surface of the tower body is provided with a gel coat resin anti-aging layer. The gel coat thickness of the gel coat resin anti-aging layer is not less than 0.5mm; at the same time, in order to The waste gas treatment situation in the tower body can be observed at any time, and an inspection window 11 is arranged in the tower body.

When the acid mist exhaust gas enters the tower body, it will not be evenly distributed to the entire cross section of the tower body. The packing layer 4 helps to improve the absorption efficiency.

After the waste gas enters the packing layer, the spray liquid is transported by the acid and alkali resistant ring water pump 12 outside the tower to the nozzle of the spray head 5 and sprayed into the waste gas, so that the absorption The liquid or washing liquid is evenly distributed in the purification tower and fully reacts with the exhaust gas. The treated exhaust gas is under the action of the swirl plate 6, so that the liquid in the air flow is separated under the action of centrifugal force, and the liquid component in the air flow is removed. The air flow through the swirl plate 6 flows through the dehydration layer 7 again, and the liquid droplets in the air flow are left in the dehydration layer 7 due to inertia, thereby further removing the solid pollutants in the liquid droplets. After being treated by this purification tower The exhaust gas meets the relevant environmental protection standards, and then is discharged into the atmosphere through the gas outlet.
