Description

A coating room exhaust gas treatment structure

Technical Field

The utility model relates to the technical field of coating chambers, in particular to an exhaust gas treatment structure of a coating chamber.

Background Art

Paint spraying mainly produces paint mist and organic waste gas pollution. Paint is atomized into particles under high pressure. During spraying, some paint does not reach the surface of the object being painted, but diffuses with the airflow to form paint mist. The organic solvents in the paint mist—benzene, toluene, and xylene are highly toxic solvents. They are emitted into the air during operation, polluting the environment and endangering people's health. Therefore, the waste gas produced by the product must be discharged after being treated to meet the standards.

After searching, the existing Chinese patent with publication number CN219333738U discloses a painting waste gas treatment device, which effectively removes formaldehyde, benzene and TVOC in the painting waste gas through the combination of an exhaust fan, an air pipe, a blower, an air duct, a treatment box, an isolation plate, a sealing door panel, an exhaust port, a limit plate, a sealing strip, a formaldehyde removal layer, a benzene removal layer and a TVOC removal layer, thereby avoiding the emission of harmful gases in the painting waste gas into the air and causing pollution to the working environment.

The above-mentioned technical solution has the following defects: although such a spray room structure can collect and treat the exhaust gas from the top through an exhaust fan, the spray exhaust gas fills the entire spray room during the actual spraying process, and the exhaust gas collection only from the top is not comprehensive enough. In order to further improve the exhaust gas collection efficiency and treatment effect of the painting room, a painting room exhaust gas treatment structure is proposed, which can collect and treat the painting exhaust gas on multiple sides, so that the painting exhaust gas can be better collected, and the exhaust gas is treated by a combination of a water curtain purification method and an activated carbon adsorption method, thereby improving the exhaust gas treatment effect.

In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
