VOCs waste gas treatment system and waste gas treatment method

Abstract

The invention provides a VOCs (volatile organic compounds) waste gas treatment system and a waste gas treatment method, relates to the technical field of waste gas treatment, and solves the technicalproblems of increased load and increased operation cost of waste gas treatment equipment during direct purification treatment due to large VOCs waste gas amount and low concentration generated duringworking of existing printing equipment. A conveying pipeline of the treatment system is connected with a waste gas exhaust port of a printing unit, the conveying pipeline is connected with a combustion furnace, and the combustion furnace is used for combusting VOCs waste gas conveyed in the combustion furnace through the conveying pipeline; when it is detected that the concentration value of the VOCs waste gas exhausted by the printing unit is not smaller than a preset value, the waste gas exhausted by the printing unit can be directly exhausted to the combustion furnace through the conveyingpipeline; and when it is detected that the concentration value of the VOCs waste gas exhausted by the printing unit is smaller than a preset value, the waste gas exhausted by the printing unit can beexhausted to a next printing unit through the conveying pipeline to be accumulated and thickened or can be exhausted into a VOCs waste gas storage pipe through the conveying pipeline. The VOCs waste gas treatment system and the waste gas treatment method are used for realizing energy conservation under the condition of treating the VOCs waste gas.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a VOCs waste gas treatment system and a waste gas treatment method. Background technique [0002] Volatile organic compounds, commonly referred to as VOCs, most VOCs are toxic, and some VOCs are carcinogenic. Most volatile organic compounds are flammable, explosive, and unsafe. Volatile organic compounds react photochemically with nitrogen oxides, hydrocarbons and oxidants in the atmosphere under sunlight to generate photochemical smog, which is harmful to human health and crop growth; they stimulate People's eyes and respiratory system endanger people's health and endanger the growth of crops. When the printing system is working, it will generate VOCs waste gas, which will be directly discharged into the atmosphere and cause air pollution. Contents of the invention [0003] The purpose of the present invention is to provide a VOCs waste gas treatment system and a...
