A multi station welding smoke purifier cannot do without three devices: pipeline system, fan system, and filtration system. In these three systems, the structure and function of different configurations are different, but the basic principle is the same, just like a person wearing a mask. The pipeline connects the mechanical and filtration system, and the fan works to create negative pressure and suction in the pipeline. The main ones are the configuration of the fan and the performance of the filter cartridge.

The configuration of the fan is calculated based on the arrangement of the number of machines in the production workshop, which requires professional personnel to calculate the configuration so that the air volume of each machine's filter interface is consistent, in order to effectively remove dust. The dust removal filter bag should be selected according to different environments, and the nature of the welding smoke generated in different workshops is the same.

The airflow of welding smoke is transported to the guide chamber of the filter cartridge through the fan. The airflow velocity decreases under the action of the guide plate, and heavier welding smoke falls into the ash bin under the action of gravity. Other lighter and finer dust particles are adsorbed on the outer surface of the filter cartridge along with the airflow. After being filtered by the filter cartridge, the clean gas enters the exhaust chamber and is discharged outside. As the filtering process continues, more and more welding fumes will accumulate on the outer surface of the filter cartridge, which will increase the operating resistance of the system and reduce the dust removal efficiency of the system. Therefore, according to the characteristics, the pulse amplitude and pulse frequency can be set on the pulse controller. After setting the pulse amplitude and frequency, the system will automatically complete the filtering and cleaning process during operation, greatly increasing the filtering efficiency and extending the service life of the filter cartridge.
