Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment, in particular to a multi-effect treatment device for chemical tail gas. Background Art

[0002] Chemical waste refers to toxic and harmful gases discharged from chemical plants during chemical production. Chemical waste often contains many types of pollutants with complex physical and chemical properties and different toxicities, which seriously pollute the environment and affect human health. When discharging chemical tail gas, it is usually first passed into a treatment box to allow the tail gas to react with the solution in the treatment box to purify the tail gas, and then discharged without causing air pollution. However, when the chemical tail gas is passed into the treatment box, due to the floating nature of the tail gas, the tail gas may float and rise in the treatment box, so that part of the tail gas may be difficult to contact the solution in the box, resulting in incomplete purification of the chemical tail gas.

[0003] A search was conducted on the above-mentioned issues and it was found that among the currently disclosed prior arts, there is a high-efficiency chemical machinery exhaust gas treatment device proposed in publication number CN216260006U. The device is provided by installing a plurality of air guide grooves in a treatment box, opening a plurality of air outlet holes on the sides of the air guide grooves, and then connecting pipes to the plurality of air guide grooves. The chemical exhaust gas enters the air guide grooves through the connecting pipes, and then comes out through the air outlet holes of the air guide grooves to contact the reaction solution in the box, thereby purifying the chemical exhaust gas.

[0004] However, the air outlet of the air guide groove is vertically opened on the side of the air guide groove, and some exhaust gas may still float upward when coming out of the air outlet at a higher position. If there is less solution in the treatment box, some chemical exhaust gas may have difficulty in contacting the reaction solution, thereby causing incomplete purification of the chemical exhaust gas.

[0026] In this embodiment, reference Figure 3 The lifting assembly includes a lifting frame 101, a lifting plate 102 and a cylinder 103. Two lifting frames 101 are provided.
