A vocs industrial waste gas treatment system

Abstract

The invention belongs to the technical field of waste gas treatment, and specifically relates to a VOCs industrial waste gas treatment system; including an air pump, a waste gas collection pipe, an air blowing module, a filtering module, a dust sweeping module, a UV photocatalytic processor, a plasma processor and an exhaust system. The air pump is used to extract the exhaust gas and transport the exhaust gas to the air blowing module; the air blowing module is connected with the filter module, and the air blowing module is used to blow the exhaust gas into the filter module intermittently; the filter module and the ash sweeping module are integrated And the filter module is connected with the UV photocatalytic processor; the dust sweeping module and the filter module are detachably connected; the UV photocatalytic processor is connected with the plasma processor, and the plasma processor is connected with the exhaust pipe; Remove the dust in the exhaust gas to improve the catalytic effect of the catalyst in the photocatalytic method or plasma method, thereby improving the treatment efficiency of VOCs exhaust gas.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, in particular to a VOCs industrial waste gas treatment system. Background technique [0002] When painting in the painting workshop, the air in the spray booth contains a large amount of dust and VOCs exhaust gas. These exhaust gases are very harmful to the human body. The treatment of exhaust gas in the paint workshop is mainly to reduce the emission of exhaust gas and control the exhaust gas. Governance takes place in two ways. Among them, photocatalytic method and ion method can be used to treat VOCs exhaust gas, but whether it is to use photocatalytic method to treat VOCs exhaust gas or plasma method to treat VOCs exhaust gas, catalysts are needed, but the VOCs exhaust gas in the painting workshop contains a large amount of Too much dust will affect the catalyst activity in the photocatalytic method and plasma method, and some dust will directly cover the catalyst, seriously affe...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned Patent Document 1, the waste gas of VOCs is processed through a scrubber, a dry filter box, a gas processor, and an induced draft system in sequence. The dust in the waste gas can be removed by the scrubber, but washing the waste gas with water will make part of the waste gas dissolve in water. A large amount of waste water to be treated is produced, causing secondary pollution, and multiple waste water treatment processes are added, which makes the treatment efficiency of VOCs waste gas low and the cost of VOCs waste gas treatment increases
