Comparison of advantages and disadvantages of centralized and mobile welding smoke purifiers

The centralized and mobile welding smoke purifier are both highly efficient equipment for purifying welding smoke, which is also a kind of filter cartridge dust collector. Therefore, the core purification principle of the mobile and centralized welding smoke purifier is the same. The filter cartridge is used as the filter element, and the welding smoke particles in the flowing welding smoke are intercepted by using the aperture of only 0.3μm on the surface of the filter cartridge. The filtered air is discharged.

However, the two are very different, the centralized welding smoke purifier is large, occupies a wide area, and the corresponding amount of welding smoke is also much, and the purification efficiency of welding smoke in the workshop is better. Centralized welding smoke purifier is not a specification of finished products, but according to the workshop welding smoke volume, station size distribution of custom, through advance calculation, first determine the size of the suction hood and the position of the pipe opening, followed by the number of filter cartridges and air volume required to deal with welding smoke, and finally according to the size of the host and user wishes to decide whether the host is placed indoors or outdoors.

When the equipment is running, the wind will transport the welding smoke from the pipe to the main machine for centralized processing, and the purified air is discharged into the 15m altitude, so the centralized welding smoke purifier is not only more suitable for the workshop with many stations and large workpieces, the workshop dust removal effect can be achieved is also higher, and it has never lost in the environmental protection inspection, which is very reliable.

Mobile welding smoke purifier is a single form, a station a welding smoke purifier, the model is fixed, the air volume is generally not more than 4000m3/h, the suction hood area is smaller, the amount of welding smoke processed is not as large as the centralized welding smoke purifier, but it is equipped with casters at the bottom, mobile flexible, better suction effect for spot welding operations, and the mobile price is cheap. It is more attractive for small and medium-sized factories, although the mobile will discharge the treated air directly into the workshop, the emission is also within the standard of 5mg/m3, and can also cope with environmental protection checks.
