Description
Technical Field
[0001] The utility model relates to the technical field of waste gas treatment, in particular to a multi-layer filtering waste gas treatment system. Background Art
[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life. These waste gases may have serious impacts on the environment and human health. Common sources of waste gas include chemical plants, steel plants, pharmaceutical plants, coking plants and refineries. These plants will emit a large amount of waste gas during the production process, which may contain harmful substances such as sulfides, nitrogen oxides, volatile organic compounds, etc.
[0003] In order to reduce the impact of exhaust gas on the environment and human health, corresponding treatment measures need to be taken. Common exhaust gas treatment methods include activated carbon adsorption. In addition to toxic and harmful gases, exhaust gas is often accompanied by solid particles and atomized liquid particles. Solid particles can easily cause the pores of activated carbon to be blocked, while atomized liquid particles will affect the adsorption performance of activated carbon, resulting in a decrease in the adsorption effect.
[0004] In order to solve the above technical problems, a multi-layer filtering exhaust gas treatment system is proposed. Utility Model Content

The air washing pool located at the bottom of the exhaust gas treatment base box can store a certain amount of clean water. The exhaust gas can be passed into the air washing pool so that the solid particles in the exhaust gas can be separated from the exhaust gas. The exhaust gas after water washing can be separated from the atomized liquid particles in the exhaust gas by a dehydration mechanism. The exhaust gas is finally discharged after adsorption by the activated carbon plate inside the exhaust pipe.
[0008] As an optimal technical solution of the utility model, a plurality of drainage pipes are fixedly connected at the junction of the exhaust gas input air duct and the exhaust gas treatment base box.

[0009] The waste gas transported through the waste gas input duct can enter the waste gas treatment base box with the help of the drainage pipe. The air outlet at the bottom of the drainage pipe is located inside the gas washing pool. The waste gas can come into contact with the clean water inside the gas washing pool when discharged from the tail of the drainage pipe. The solid particles carried in the waste gas enter the water, thereby separating the solid particles in the waste gas from the waste gas and reducing the pressure on the subsequent activated carbon.

The left and right sides of the upper retention plate are formed with a guide side plate 1, and the left and right sides of the lower retention plate are formed with a guide side plate 2. A conical guide cover is formed on the lower surface of the middle part of the lower retention plate, and a drainage port is opened through the surface of the conical guide cover.
[0013] When the exhaust gas with atomized particles passes through the water cut-off module, due to the inertial impact of the exhaust gas, the atomized particles collide with the guide side plate one and the guide side plate two. When the gathered droplets are so large that the gravity generated by themselves exceeds the combined force of the gas rising force and the liquid surface tension, the droplets are separated from the surface of the guide side plate one and the guide side plate two, and the gathered droplets can finally enter the conical guide cover and enter the gas washing pool through the drainage port on the surface of the conical guide cover.

The thermal pad can transfer the heat to the activated carbon plate inside the exhaust duct, and the activated carbon plate is heated by heat conduction, so that the activated carbon plate can be kept dry to prevent its adsorption performance from being affected by the exhaust gas containing water.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] 1. The waste gas transported through the waste gas input duct can enter the waste gas treatment base box with the help of the drainage pipe. The air outlet at the bottom of the drainage pipe is located inside the gas washing pool.

The solid particles carried in the waste gas enter the water, thereby separating the solid particles in the waste gas from the waste gas and reducing the pressure on the subsequent activated carbon.
[0018] 2. When the waste gas with atomized particles passes through the water cut-off module, due to the inertial impact of the waste gas, the atomized particles collide with the guide side plate 1 and the guide side plate 2.

Then, the waste gas to be treated can enter the waste gas treatment base box 1 through the waste gas input air duct 3. The waste gas transported through the waste gas input air duct 3 can enter the waste gas treatment base box 1 through the drainage pipe 301.

When the exhaust gas with atomized particles passes through the water cut-off module, due to the inertial impact of the exhaust gas, the atomized particles collide with the guide side plate 1 501 and the guide side plate 2 601 and are When the aggregated droplets are so large that the gravity generated by themselves exceeds the combined force of the gas's rising force and the liquid's surface tension, the droplets are separated from the surfaces of the guide side plate 1 501 and the guide side plate 2 601, and the aggregated droplets can finally enter the conical guide cover 602, and enter the gas washing pool 4 through the drainage port 603 on the surface of the conical guide cover 602. After completing the early exhaust gas treatment, the subsequent pressure of the activated carbon on the exhaust gas adsorption can be greatly reduced, and the activated carbon plate 8 inside the exhaust pipe 702 can adsorb the organic matter in the exhaust gas.
