A formaldehyde neutralization, degradation, condensation and purification treatment device for spray paint waste gas in a paint spray booth

Abstract

The invention discloses a formaldehyde neutralization, degradation, condensation and purification treatment device for spray paint waste gas in a paint spray booth. chamber, the bottom surface of the spray chamber is close to the top surface of the combustion chamber. The present invention realizes the use of a horizontal square box to cooperate with an S-shaped pipeline, and detects the acidity and alkalinity of the waste gas into the chute through the PH test board, and then carries out alkali The sliding coverage of the formic acid gas by the active substance realizes the neutralization reaction, stabilizes the activity of the exhaust gas, and then cools and recovers the organic gas through the cooling tube frame, and then guides the pretreated exhaust gas into the S-shaped pipeline for post-purification treatment, achieving dual-channel The sliding propulsion effect of the erection of classified acid-base neutralization improves the efficiency of cooling and precipitation of organic gases to facilitate secondary utilization, and also ensures the connectivity of pipeline care, improves the protection of pipelines by exhaust gas pretreatment and the preliminary analysis of exhaust gas acidity and alkalinity, It is convenient for later purification.

Description

technical field [0001] The invention relates to a formaldehyde neutralization, degradation, condensation and purification treatment device for waste gas from spray paint in a paint spray booth, which belongs to the field of waste gas treatment from paint spray. Background technique [0002] The spray booth is a paint processing room for furniture such as large-scale building materials and alloy frames. The closed space prevents air pollution from leaking out. It is connected to the exhaust gas treatment equipment to facilitate, quickly and directly purify the exhaust gas, achieve an integrated work treatment effect, and improve the overall work performance and efficiency. , but in terms of the pipeline transportation of the initial suction exhaust gas, the protection of the chemical characteristics of the exhaust gas is slightly insufficient. The shortcomings of the current technology to be optimized are: [0003] Spray paint often emits a pungent smell. This is because form...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a formaldehyde neutralization, degradation and condensation purification treatment device for spray paint waste gas in a paint spray booth, so as to solve the irritating smell that often occurs when spray paint, which is caused by the volatilization of formaldehyde in the paint liquid In the air, the aqueous solution of formaldehyde is slightly acidic, and it is difficult to treat the gas after painting. Formaldehyde can be slowly oxidized into formic acid in the air, which is slightly acidic and corrosive, and has a corrosive effect on the pipelines of waste gas treatment equipment, causing Adhesive corrosion on the inner wall of the pipe leads to thinning and cracking of the pipe wall, a small amount of leakage of spray paint exhaust gas, gas poisoning of the staff, and serious carcinogenic hidden dangers, which is very dangerous. Relatively lacking, only to purify the exhaust gas from the whole tower body, it will not take into account the care of other connecting parts
