Welding fumes enter the high-voltage electrostatic field with the air. The interior of the electrostatic field has a double-zone structure. The front zone is the concentration polarization zone (positive ion zone). The fume is caused by arc discharge in the electrostatic field after passing through the concentration polarization zone. The positive charges collide and hydrolyze, which then polarize the concentration of soot particles floating in the air; after the energized particles pass through the dust collector area (absorption area), they are driven to clean air co2 laser by the Coulomb force of the electrostatic field. After the filter reaches the pole piece, it loses its positive charge and is absorbed on the pole piece to complete the purification of the smoke and dust.

Application of PURE-AIR to dust extraction rectification examples

3. For the smoke and dust in all welding workshops: the method of collecting direct emissions can be used to carry out purification. For all workshops, many welding positions carry out overall purification. Exhaust air filter for fiber laser uses the basic principle of gas heating and cooling to be hierarchical, constantly pouring into the ultra-low temperature fresh air system from the bottom of the workshop, generating ultra-low temperature gas lakes in the work area; welding fume is continuously increased with the entrainment of the hot cyclone and the fresh air system . The fresh air on the wooden floor slowly moves upward, producing a fluidity similar to an upward uniform flow, so the turbid air in the work area is replaced by the fresh air system afterwards. When it is stable, the indoor air quality will produce two types of areas in terms of temperature and concentration values: high temperature mixed flow area and ultra-low temperature clean area.

The replacement of natural ventilation and purification for all industrial plants is suitable for places where the welding stations are extremely decentralized, the aerial cranes are frequently operated, and the auxiliary fixtures and tools are complicated.
