Workshop waste gas treatment system

Abstract

The invention discloses a workshop waste gas treatment system, which comprises a water washing tower, a defogging box, an active carbon box and a fan, wherein the water washing tower is positioned atthe upper stream of the defogging box; the defogging box is positioned at the upper stream of the active carbon box; the active carbon box is positioned at the upper stream of the fan; the water washing tower comprises a tower body, a first air outlet, a first water inlet and a pollution discharging opening; the first air outlet is positioned at the upper end of the tower body; the first air inletand the pollution discharging opening are positioned in the side wall of the tower body; a first filling material support frame, a gas-liquid mixing layer, a spraying assembly, a second filling material support frame, a first defogging layer and a tower top screen plate are sequentially arranged inside the tower body from bottom to top. The workshop waste gas treatment system has the advantages that dust, grease and harmful gas in waste gas can be effectively removed; the treatment efficiency is high; the system operation is stable; the treated waste gas meets the national emission standard.

Description

technical field [0001] The invention belongs to the technical field of exhaust gas treatment, in particular to a workshop exhaust gas treatment system. Background technique [0002] Industrial waste gas usually contains pollutants such as benzene, toluene and sulfide, which are usually harmful to human health and the environment. For example, these pollutants enter the human body through breathing, skin contact and digestive tract, which will cause endocrine dysfunction and affect the human immune function, cardiovascular and central nervous system. Therefore, the issue of waste gas treatment has received great attention. [0003] There are many methods for waste gas treatment, such as spraying method, stripping method, activated carbon adsorption method, plasma method, etc., but there are problems of large dosage, secondary pollution, large space occupation and high cost, so that enterprises are restricted affect development. [0004] Chinese Patent Publication No. CN 107...

AI Technical Summary

Problems solved by technology

Although the particulate dust, smoke and other harmful components in the exhaust gas are effectively removed, the amount of exhaust gas treatment per unit time is low, and the exhaust gas treatment effect is not good.
