Formaldehyde neutralization, degradation and condensation purification treatment device of paint spraying exhaust gas in spray booth

Abstract

The invention discloses a formaldehyde neutralization, degradation and condensation purification treatment device of paint spraying exhaust gas in a spray booth. The structure of the device comprisesa horizontal square box, an electric cabinet, an S-shaped pipeline, a conical top cover plate, observation windows, a spray chamber and a combustion chamber, and the bottom surface of the spray chamber clings to the top surface of the combustion chamber. The horizontal square box cooperates with the S-shaped pipeline, a pH test board is used to detect the pH value of the exhaust gas, the exhaust gas is introduced into a chute path, the neutralization reaction is achieved through sliding coverage of a formic acid gas with an alkaline substance to stabilize the activity of the exhaust gas, organic gas is cooled and recovered through a condense tube rack body, and the pretreated exhaust gas is introduced into the S-shaped pipeline, and is undergoes later purifying treatment, so the erection sliding promotion effect of dual-path classified acid-base neutralization is achieved, the high efficiency of cooling separation of the organic gas is improved, reuse of the organic gas is benefited, the communication effect of pipeline care is ensured, the protection of exhaust gas pretreatment on the pipeline and the preliminary analysis of the pH value of the exhaust gas are improved, and the exhaust gas can be easily purified later.

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
