Multi station welding fume treatment, welding workshop fume processing parameters
Instructions
Dust containing gas through the suction inlet through the pipe into the cartridge type dust cleaning equipment, because the flow section suddenly expand and the air distribution plate, a part of the coarse particles in the air and under the force of inertia settlement in the ash hopper; fine granularity, density of small dust particles into the dust filtering chamber, through diffusion and Brown the sieve combined effect, the dust deposition on the filter surface, the purified gas enters a clean air chamber from the exhaust pipe through the exhaust fan. The resistance of the filter drum dust cleaning equipment increases with the increase of the dust layer thickness. When the resistance reaches a specified value. The PLC program control on-off pulse valve, a first compartment poppet valve closed, air filter will be truncated, then the electromagnetic pulse valve open, compressed air and a short time in the case on the rapid expansion of the influx of the cartridge, the cartridge expansion deformation vibration, and erosion in the reverse gas under the action of attachment of dust in the outer surface of the bag on the stripped into ash hopper in. After the ash is finished, the electromagnetic pulse valve is closed, the lifting valve is opened, and the filter state is restored. The ash cleaning room is carried out in turn, from the first room ash cleaning to the next ash cleaning for a clear ash cycle. Off the dust in the hopper through the ash unloading valve into the discharge.
Working principle：
Pulse type cartridge dust collector is provided with an air inlet, filtering cylinder, air outlet, air bag, pulse control instrument, injection valve, nozzle, filter cartridge is made of polyester fiber folded, rolled, the lower end is closed, the center of the upper end of the blowing mouth. Dusty gas from the inlet into the dust then, the airflow speed slows down, the coarse particles from the air settlement to the dust collecting chamber, fine dust with the air flow through the filter cartridge is blocking on the outer surface of the filter drum, clean gas is out from the outlet; when the dust on the surface of the filter cylinder is thick, the pulse controller gives instructions to open the injection valve, compressed air bag by blowing high-speed spray and spray device induced by several times in the surrounding air into the cartridge, and from inside to outside the rapid injection, filtering cylinder dust blowing into the dust collecting chamber, the cleaning bucket is discharged. Dust cleaning dust using pulse injection method, not only to achieve a thorough cleaning, without damage to the filter cartridge, so that the filter life can be guaranteed. The ash cleaning process is automatically controlled by a pulse controller, which can be controlled by pressure or time.
