AI Technical Summary

Technical Problem

In the existing electroplating waste gas treatment methods, the contact time between the waste gas and the absorbing liquid is short, resulting in a low absorption rate and a large exhaust pressure, which may lead to the problem of poor emissions.

Method used

A waste gas purification and treatment equipment is designed to supercharge the exhaust gas through the air collecting hood and the booster pipe, and the drainage pipe and the spoiler discharge assembly are used to allow the exhaust gas to enter the treatment box at multiple angles, increasing the contact area and time with the treatment liquid.

Benefits of technology

By increasing the contact range and time between the waste gas and the treatment liquid, the treatment efficiency of the waste gas is improved, the problem of improper emissions is avoided, and the uniform dispersion and full effect of the absorbed liquid are ensured.
