The long bag pulse dust collector is a kind of new type and high efficiency bag dust collector developed on the basis of the conventional short bag pulse dust collector. It has the advantages of large air volume, good cleaning effect, high dust removal efficiency, reliable operation and easy maintenance. The characteristics of small area, mainly used in metallurgy, building materials, chemicals, boiler flue gas dust and other industries dust control and material recovery.
Highlight the advantages
1, with advanced thin throttle and off-line cleaning mechanism, advanced technology, reliable, clean thoroughly;
2, the design of a reasonable inlet flow and ash hopper diversion device to solve the general bag filter often produce sub-chamber air flow uneven phenomenon;
3, the design of a special large reserves of gas storage bag, both to meet the use of high pressure air supply, but also to meet the use of low pressure air supply;
4, the top of the filter bag with spring up ring type, not only the sealing effect is good, but also in the replacement of bags when fast, simple,
5, in the structure of the design of the cage, according to different conditions have a variety of structural types of choice, the manufacture of bags of indicators than the industry standard increased by about 50%
6, electromagnetic pulse valve with high quality parts, the diaphragm of the long service life;
7, the control system uses advanced programmer, with differential pressure, timing, manual three kinds of control methods, the dust off the off-line valve, pulse valve, ash discharge valve to achieve full automation control.
working principle
ZL series of long bag pulse dust collector mainly by the upper box, the box, ash bucket, legs, filter bags and injection devices, ash removal device and other components, the working principle is dust from the dust into the air inlet, Through the inlet manifold into the sub-room ash bucket, and in the gray diversion device under the diversion, large particles of dust are separated, directly fall ash bucket, the remaining dusty gas into the middle of the box, the dust is adsorbed On the outer surface of the filter bag, the filtered clean gas enters the upper tank through the filter bag and is discharged into the atmosphere through the off-line valves and exhaust ducts. As the filtration conditions progress, the dust on the filter bag , When the resistance of the device reaches a limited resistance value (generally set to 1500Pa), by the cleaning control device by the differential pressure set value or cleaning time set automatically turn off the room off-valve, and then press the set program to open Electric control pulse valve, to stop the air blowing, the use of compressed air instantly so that the pressure inside the bag suddenly surge, the dust on the filter bag shake off (even if the sticky dust can be completely removed) to the hopper, Gray body discharge.
Structure and composition
Dust catcher mainly by the box, the box, ash bucket, legs, filter bags and injection devices, ash removal device and other components, structural features are:
1, the upper box is divided into several rooms, each room has a poppet valve to achieve off-line cleaning, off-line maintenance;
2, pneumatic exhaust valve with cylinder control, stable, reliable, open and close speed, close tight, no leakage;
3, pneumatic exhaust valve with a vertical installation form, compared with the horizontal installation method is more convenient to repair;
4, the filter bag with the elasticity of the bag ring to its self-locking, sealed in the flower plate hole, and the board connected to the seal is good, to ensure a lower emission concentration, and installation and replacement of fast and convenient;
5, the nozzle is optimized for the injection of short tube, cleaning effect is good;
6, equipment inspection and maintenance positions are equipped with safety fence and walk Taiwan, easy to safe and convenient equipment maintenance and routine maintenance.
