Environment-friendly printing waste gas treatment system

Abstract

The invention relates to an environment-friendly printing waste gas treatment system. The system comprises a body and a water supply tank, a water inlet pipe is arranged in the water tank, and the water inlet pipe is detachably provided with a plurality of spraying pipes fixedly connected with the water tank; a plurality of water outlets are formed in the spraying pipes, water outlet columns are arranged at the water outlets of the spraying pipes in a communicating mode, and a spray head is detachably arranged on each water outlet column; cleaning blocks are fixedly arranged at the positions,above the water outlet columns, of the spraying pipes, cleaning frames are hinged to the cleaning blocks, and driving pieces for driving the cleaning frames to swing are arranged on the cleaning blocks; and a cleaning rod is arranged on each cleaning frame in a sliding mode, the cleaning rods is inserted into the water outlet columns, and cleaning pieces used for dredging the water outlet columnsare arranged on the cleaning rods. The disassembling effect between the spray heads and the water outlet columns can be achieved conveniently, the water outlet columns can be cleaned conveniently, andthe treatment quality of printing waste gas is improved.

Description

technical field [0001] The invention relates to the technical field of printing waste gas treatment, in particular to an environmental protection treatment system for printing waste gas. Background technique [0002] Industrial waste gas usually contains pollutants such as waste gas and dust, which are usually harmful to human health and the environment. The printing waste gas components in the printing industry usually include benzene, toluene, xylene, acetone, methyl ethyl ketone, lipids, ethers and other highly volatile organic waste gases, as well as two-phase suspensions formed after volatilization or atomization of solid materials and solvents The material escapes into the surrounding air and also pollutes the air. Exhaust gas pollutants in printing workshop exhaust gas treatment and printing factory exhaust gas treatment come from inks, solvents, thinners and pigments in printing processes such as printing and ink mixing. Organic waste gas is continuously volatilized...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: due to the presence of some dust particles in the exhaust gas, during the spraying process of the spray water pipe, the water outlet of the spray water pipe adheres to the particle impurities, and as the particles accumulate gradually, the spray water pipe The water outlet on the top is blocked, which affects the cleaning effect of dust particles and impurities in the exhaust gas
