Sunshine workshop dust purification workshop dust purification EIA
1, application place
The utility model is suitable for the working places of producing flue gas, such as arc welding, carbon dioxide protection welding, MAG welding, carbon arc air gouging welding, gas cutting and welding, etc.. Three, the working principle of dust in the work by suction hood suction smoke purifier, first through a layer of fire resistance purifier, separation of particles can produce on Mars by granular and polished, preliminary filtered air enters into the second layer filter protective plate, the protective plate to prevent the residual shunt and direct access to Mars the main filter element; the separated gas containing dust and then enter the third layer of the main purification filter, the main filtering effect of the filter element is as high as 99.9%, due to the high efficiency of filtering accuracy of the main filter can reach indoor emission standards, filtered clean air directly into the indoor air outlet is circulated through the purifier.
A mobile welding smoke purifier configuration of a suction arm, the bottom is equipped with 2 directional, 2 universal casters with polyurethane brake device, used for welding mobile station. The suction arm can rotate 360 degrees by pulling the hood on the handle, can be easy and flexible with the intention of the operator to position and dust suction angle, and self in the air under the action of the external force; the optional 2m, 3M flexible suction arm; suction hose with high temperature resistant, flame retardant, real wear resistant composite material not because Mars wear after cracking, longer service life; for the 150mm. arm tube diameter
Working principle
1 San Da deep filter
This material is loose, the gap between the fiber and the fiber, such as polyester needle felt, a gap is 20 ~ 100 m. When the average particle size of dust in the 1
M, in the filtering operation, a small part of the particles will enter the filter inside the detention, the other part will escape through the filter. Most of the dust attached on the filter surface, forming a layer of filter layer, the filtering layer will contain dust filter dust in the air. Enter the internal filter small particles, the resistance increases, filter material hardens, until the end of life.
Show that the manufacturing technology of mobile welding fume dust remover:
1) equipment shell bending processing, welding using CO2 gas shielded arc welding, welding intermittent internal, external continuous welding, testing according to the national standard; gas protection welding stability, welding heat deformation zone is small, the welding stress is small, no welding slag, no oxide, ensure the dust remover body welding residual stress. To ensure the welding quality, effectively prevent the equipment used in the process due to the stress caused by the release of body deformation and cracking, improve equipment reliability, ensure the tightness of welding.
2) before the equipment inside and outside surface grinding smooth, spray treatment.
3) filter material used in flame retardant paper material, has excellent filtration performance and easy cleaning
