First, the use of premises 
 Mobile welding fume purifier KHY-Type II, used for welding, polishing, cutting, grinding and other processes produce smoke and dust purification and recovery of rare metals and precious materials can purify a large number of suspended in the air of harmful small metal particles. With high purification efficiency, low noise, flexible, and small footprint. 
 Workplace of the flue gas for arc welding, carbon dioxide shielded welding, MAG welding, carbon arc gouging welding, gas Melting cut, special welding, etc.. 
 Second, the structure and composition 
 The main components include: the universal arm vacuum, high temperature vacuum hose, vacuum hood (with air volume control valve), the resistance Huowang, flame-retardant efficient filter, pulse jet cleaning device, pulsed solenoid valves, differential pressure gauge, clean room, activated carbon filters, Shen ash drawer combination of flame retardant sound-absorbing cotton, the new Korean casters with brake fans, ABB Motors and electrical control boxes and other. 
 Third, the principle 
 Welding smoke exhaust fan gravitational by universal inhalation equipment vacuum hood air inlet device into outlet with a spark arrestor, sparks were delayed by the flame arrester, smoke gases into the settling chamber, the use of gravity with the upstream airflow, the first coarse dust directly down to the hopper, and particulate soot filter trap to the outer surface, clean gas purification by the cartridge filter from the center of the filter into the clean room, clean air is adsorbed by the activated carbon filter further purified by a outlet discharge standards. 
 Fourth, the equipment advantage 
 1, has a dedicated turbine fan and motor, the use of anti-overload circuit to prevent motor burnout, safety, performance and stability. 
 2, using the built-in central central PLC control mode, simple structure, easy to operate. 
 3, the pulse-jet cleaning Automatic cleaning: using the full range of automatic rotary cleaning dust filter, the filter surface cleaning is more thorough, clean, always ensure that the dust collector has a constant suction air flow; air compressor part high pressure hose connected to the bottom of the high-pressure inlet to protect the purifier is always in good working condition. (According to user needs design automatically or manually controlled) 
 4, the cartridge using the USA of imported materials, long life, can absorb the 0.3μm dust particles, have a good filter effect on the wet and sticky dust. 
 5, universal suction arm 360 degrees freely, suction of flue gas from the flue gas occurred, greatly improving the collection rate of soot, to ensure the health of workers. 
 6, inside the purifier of three protective measures against fire hazards and large particles of slag using cleaner longer life, more secure. 
 7, the clean air from the air vents of the grill like the direction of uniform guide and decentralized, and thus reduce the noise to a minimum. 
 8, with special brakes Korean casters, convenient device free to move and positioning. 
 9, photoelectric control, open, shut down, energy efficient, cantilever cover with a lighting device (optional). 
 10, purification inside supplies stable performance, easy to replace.
