Technical Field

[0001] The utility model belongs to the technical field of compressor impeller processing, in particular to a harmful gas treatment device for the inlet and outlet of an impeller spray chamber. Background Art

[0002] The compressor impeller, also known as the working wheel, is the only element in a centrifugal compressor that does work on the airflow. It is the most important component on the rotor and is generally composed of parts such as a disc, a wheel cover and blades. Under the action of the impeller blades, the gas rotates at high speed with the impeller. The gas is affected by the centrifugal force of the rotation and the expansion flow in the impeller, which increases the pressure after it passes through the impeller.

[0003] After the impeller is processed and formed, it needs to be sprayed to increase the service life of the impeller. This step is usually carried out in the spray room. After the impeller in the spray room is painted, the closed door needs to be opened before the impeller in the spray room can be taken out. At this time, due to the presence of paint, harmful gases such as formaldehyde and benzene will overflow from the inlet and outlet of the spray room. Therefore, a harmful gas treatment device for the inlet and outlet of the impeller spray room is needed, which can collect the gas at the inlet and outlet of the spray room, treat it and then discharge it to avoid the harmful gas in the spray room overflowing to the workshop and endangering the health of the workers.
