Chemical waste gas often contains many types of pollutants with complex physical and chemical properties. Chemical waste gas contains a large amount of pollutants. If it is directly discharged into the atmosphere without treatment, it will cause serious harm to the environment and human health. Therefore, in order to protect the environment, chemical gas treatment devices are usually used to treat waste gas.

[0003] For example, the patent specification of an existing Chinese patent (publication number: CN218107253U) discloses a chemical gas collection and processing device for chemical industry.

If the exhaust gas is not treated sufficiently, it means that the pollutants in the exhaust gas are not effectively removed or reduced to a level that meets environmental regulations or safety standards, which will still cause environmental pollution.

[0005] In view of this, a chemical gas collection and processing device is provided to overcome the above-mentioned defects. Utility Model Content

[0024] In specific implementation, when the utility model is used, when the exhaust gas enters the tank body 1 through the exhaust gas inlet pipe, the water pump 4 is started, and the exhaust gas cleaning liquid in the water tank 5 passes through the water suction pipe 17 and the water inlet pipe 3, and is finally sprayed into the tank body 1 from the nozzle 2, so as to perform the first cleaning on the exhaust gas entering the tank body 1, and the water sprayed from the nozzle 2 will be filtered through the filter 19 and then flow into the water tank 5, forming a water cycle, so that the exhaust gas cleaning liquid in the water tank 5 can be recycled. When the exhaust gas cleaning liquid becomes turbid and saturated after being used for a period of time, the piston of the water outlet hose at the bottom of the water tank 5 can be pulled out to discharge the exhaust gas cleaning liquid in the water tank 5, and then new exhaust gas cleaning liquid can be poured into the water inlet hose to complete the replacement of the exhaust gas cleaning liquid in the water tank 5.
