Tail gas filtering device and coating equipment

Abstract

The invention provides a tail gas filtering device and coating equipment. The tail gas filtering device comprises at least one filtering unit, a first mounting unit and a second mounting unit, and the filtering unit is convenient to replace and can be replaced in time.

Description

technical field [0001] The invention relates to the field of tail gas treatment, in particular to a tail gas filtering device and coating equipment. Background technique [0002] During the coating process, the reaction raw materials are fed into the reaction chamber for reaction, and part of the unreacted raw materials and part of the by-products generated by the reaction will form tail gas and need to be discharged from the reaction chamber in time to make the pressure of the reaction chamber Within the control range, these exhaust gases are usually harmful to the environment if they are directly discharged. [0003] The exhaust gas is usually absorbed by setting a filter bottle at the outlet position. Filter material is placed in the filter bottle, and when the tail gas treatment capacity of the filter bottle reaches the upper limit, it is replaced with a new filter bottle. For a coating equipment, the reaction chamber of the coating equipment needs to be maintained at ...

AI Technical Summary

Problems solved by technology

[0005] In the actual use process, it is found that there are still two problems in filtering with filter bottles. One problem is that the production efficiency is reduced due to shutdown. The service life of a filter bottle is about one week, which means that it needs to be shut down once a week. The problem is that the gas flow diameter of the filter bottle is small and the pressure drop is large, which causes the vacuum pump with small back pressure requirements to often alarm
