Description

Technical Field

[0001] The utility model relates to the field of dryers, and particularly relates to an exhaust gas treatment device for a dryer. Background Art

[0002] At present, a Chinese utility model with the publication number CN216825259U discloses an exhaust gas treatment device for a dryer, which includes an exhaust gas treatment protection body, a sharp airflow direction change type filtering device, and an activated carbon adsorption device. The utility model belongs to the technical field of exhaust gas treatment for dryers. Specifically, it is an exhaust gas treatment device for a dryer. By adopting the method of sharply changing the airflow direction and impact filtration, the technical effect of purifying the exhaust gas is achieved. Combined with the activated carbon adsorption layer, the gas is adsorbed and filtered to enhance the treatment effect of the gas. And an anti-blocking cleaning component is provided to effectively prevent the problem of blockage during filtration and purification.

[0003] Existing exhaust gas treatment devices cannot treat water vapor. Generally, the exhaust gas from the dryer rack is directly transported into the exhaust gas treatment device through a suction fan. Since the exhaust gas generated by the dryer contains water vapor, the water vapor passing through the activated carbon will cause part of the surface of the activated carbon to be occupied by moisture, thereby reducing its effective adsorption capacity for other pollutants, thus reducing the adsorption efficiency of harmful substances. Moreover, the water vapor will also corrode or scale the equipment, affecting the normal operation and service life of the equipment, and it is not convenient for maintenance. Generally, the exhaust gas treatment device treats the exhaust gas through a filter screen and activated carbon. During use, it needs to be maintained regularly. And generally, the cover plate and the shell of the exhaust gas treatment device are fixed by multiple bolts. When maintaining it, tools are needed for disassembly and assembly. The disassembly and assembly process is relatively cumbersome, increasing the workload and reducing the maintenance efficiency. To solve the above problems, we propose an exhaust gas treatment device for a dryer. Summary of the Utility Model
