working principle: Dust gas from the ash bucket (or the lower wide open flange) into the filter chamber, coarse particles directly fall into the hopper or ash storage, dust and gas filter bag filter, dust retention in the bag surface, net gas by the bag When the resistance of the filter bag rises to the set value, the time relay (or differential pressure controller) outputs the signal, and the programmer starts to work, and the temperature of the filter bag is increased. Open the pulse valve, so that the compressed air through the nozzle on the filter bag for cleaning, so that the bag suddenly inflated, in the reverse airflow, attached to the bag surface dust quickly from the filter bag fell into the ash bucket (or gray Warehouse), the dust discharged from the discharge valve, all the bag after the end of cleaning, dust collector to return to normal work. Pulse bag filter [2] normal work, dust from the air inlet into the hopper, due to the rapid expansion of gas volume, part of the coarse dust by inertia or natural settlement and other reasons fall into the hopper, the rest of the majority Dust particles with the air into the bag room, filtered by the filter bag, the dust particles are stranded in the filter bag on the outside, the purified gas from the bag into the upper box, and then by the valve plate hole, exhaust into the atmosphere , So as to achieve the purpose of dust. With the continuous operation of the filter, the resistance of the precipitator also increases, when the resistance reaches a certain value, the cleaning controller issued a clear command, first lift the valve plate closed, cut off the filter air; then, the cleaning controller to pulse Solenoid valve signal, with the pulse valve used as cleaning the high pressure reverse air into the bag, the bag quickly bulge, and produce a strong jitter, resulting in dust outside the filter bag shake off, to clean the purpose. As the equipment is divided into several boxes, so the process is carried out by box, a box area in the cleaning, the remaining box area is still working properly to ensure the continuous operation of the equipment. The reason why the high concentration of dust can be handled, the key is that this cleaning time required for cleaning a very short time (blowing only 0.1 ~ 0.2s).
Technical features: (1) without pre-dust removal equipment, can be a one-time treatment up to 1000mg / m3 concentration of soot, emissions less than 50mg / m3, the process is simple; (2) bag room without injection tube, machine outside the bag for convenience; (3) embedded elastic pocket, good sealing performance; (4) a small number of pulse valve, cleaning strength, rapid action; (5) machine using computer automatic control, the parameters easy to adjust, can be achieved without job * for; (6) filter bag life of more than two years; (7) easy to achieve isolation and maintenance.
Applications: Widely used in food, pharmaceutical, feed, metallurgy, building materials, cement, machinery, chemicals, power, light industry dust purification and dust recovery of dust materials.
