Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a waste gas treatment device for coating production. Background Art

[0002] Paint is an organic chemical polymer material, which mainly plays a role in protecting, decorating, concealing product defects or other special functions. During the production and preparation of paint, some organic solvents will volatilize to form harmful waste gas, such as toluene, xylene, acetone, etc. At the same time, some oxidants may also exist in the waste gas in the form of aerosols. These waste gases will not only cause environmental pollution, but also endanger the health of workers;

[0003] In order to treat the waste gas generated in the coating production process, a waste gas treatment device is usually used. For example, the authorization document with the announcement number CN214131069U discloses a waste gas treatment device for coating production. The existing waste gas treatment device generally adsorbs harmful substances in the waste gas through an activated carbon filling layer. However, since the activated carbon is directly filled in the equipment, and the adsorption of the activated carbon is saturated, it is necessary to stop the equipment and replace the activated carbon when the activated carbon is saturated, which is not convenient for long-term adsorption treatment of the coating waste gas. At the same time, the existing waste gas treatment device uses the mist sprayed by the atomizing nozzle to remove the particulate matter in the waste gas, and recycles the waste water through the water collecting bucket. However, since the position of the atomizing nozzle in the equipment is fixed, the spray dust removal efficiency of the waste gas is poor. At the same time, since the coating waste gas contains coating particles, some coatings will adhere to the water collecting bucket after dust reduction, which makes it inconvenient to clean the water collecting bucket. In addition, the existing waste gas treatment device cannot recycle the water content of the waste gas after spraying and dust reduction, resulting in a serious waste of water resources.

[0004] To this end, we provide a paint production waste gas treatment device to solve the above problems. Summary of the invention

[0053] Furthermore, the outer walls of both sides of the catalyst box 100 are penetrated by a connecting pipe 106 and a connecting pipe 2 107 respectively, and one end of the connecting pipe 106 away from the catalyst box 100 passes through the upper part of the outer wall of one side of the adsorption box 200 and extends to the inside of the adsorption box 200, and the lower part of the outer wall of the other side of the adsorption box 200 is penetrated by an exhaust pipe 209;

[0054] Furthermore, a material exchange port 210 is provided on the front end surface of the adsorption box 200, and movable doors 211 are rotatably connected to both sides of the material exchange port 210;
