Waste gas treatment device for printing

Abstract

The invention discloses a waste gas treatment device for printing. The waste gas treatment device comprises a waste gas collection pipeline, a filter device, a treatment pond device and a gas purification device, wherein the waste gas collection pipeline is used for collecting waste gas generated in a printing process; the filter device comprises a filter box and a first filter screen plate; the treatment pond device comprises a treatment pond body, an upper top cover, a second filter screen plate, a water suction pump and a water spraying device; and the gas purification device comprises a base, a gas drying device, a third filter screen, a purification gas inlet pipe and a purification outlet. The waste gas treatment device is used for collecting the waste gas generated in the printing process; through arranging the filter device, the treatment pond device and the gas purification device, the waste gas is treated and then becomes clean gas which can be emitted; the waste gas is prevented from being directly emitted to cause pollution to surrounding environment and air; a harmful component in the waste gas is removed; and the waste gas treatment device is applicable to the waste gas treatment in the printing process.

Description

technical field [0001] The invention relates to the field of waste gas treatment devices, in particular to a printing waste gas treatment device. Background technique [0002] In recent decades, my country's packaging and printing industry has developed rapidly, the scale has been continuously expanded, and the technology has been continuously updated. However, the printing process of domestic plastic packaging is still dominated by solvent-based inks and solvent-based compounding agents. In addition to containing a relatively high proportion of organic volatiles, there are still a large number of organic solvents for dilution and deployment during its use. And these many organic solvents need to be dried and volatilized during the printing or compounding process. [0003] At present, the traditional printing waste gas treatment device only plays the role of collecting the waste gas discharged from the printing machine and then discharges it in a concentrated manner. It cann...

Problems solved by technology

[0003] At present, the traditional printing waste gas treatment device only plays the role of collecting the waste gas discharged from the printing machine and then discharges it in a concentrated manner. It cannot treat the harmful substances in the waste gas, and the discharge is not up to standard, which seriously affects the surrounding environment and air quality.
