Styling machine waste gas purification treatment system

Abstract

The invention discloses a waste gas purification treatment system for a setting machine and relates to the technical field of waste gas treatment. According to key points of the technical scheme, thewaste gas purification treatment system comprises a waste gas filtering device, an efficient electrostatic spray purifier, a high-pressure water spray cylinder, a secondary treatment pool, a third-level treatment device and an exhaust cylinder, wherein a 0.15-0.3g / L reactant is added into the secondary treatment pool; the water temperature in the secondary treatment pool is maintained at 15-30 DEGC, the pH value of the water in the secondary treatment pool is maintained at 6-9, and the water in the secondary treatment pool is filtered; the reactant comprises the following components: modifiedcellulose, poly-aluminum ferric silicate sulfate and sulfuric acid; a mass ratio of the modified cellulose to poly-aluminum ferric silicate sulfate to sulfuric acid is 1:(1-2):1; and the concentration of the sulfuric acid is 2-3g / L. According to the system disclosed by the invention, the problems that the removal rate of oil smoke and particles is low and the purification rate is low when waste gases are treated by the setting machine are solved. The waste gases subjected to electrostatic spray are introduced into the secondary treatment pool dissolved with the reactant, so that the removal rate of the oil smoke and particles can be improved, and the purification rate of the waste gases is improved.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, more specifically, it relates to a system for purifying waste gas of a setting machine. Background technique [0002] The exhaust gas emitted by the setting machine not only contains a lot of smoke and dust, but also contains polyphenylene organic matter, printing and dyeing auxiliaries, grease and wax. Highly hazardous to health and the environment. [0003] In the prior art, reference can be made to the Chinese invention patent application document with the application publication number CN107930314A, which discloses a waste gas recovery system and its recovery process for a textile setting machine. The waste gas recovery system includes: a solid filter device, a spray Water washing device, adsorption device, steam generating device, oil-water separation device, condensing device, spray water storage tank and oil collection device; waste gas is purified and discharged through solid...

AI Technical Summary

Problems solved by technology

[0006] Although the existing oil fume exhaust gas purification treatment system of this dyeing and finishing machine is equipped with a water spray pretreatment device and an electrostatic oil fume removal device, the two are installed separately, which is likely to cause low removal rate of oil fume and particulate matter, and waste gas Purification efficiency is low
