Long bag low pressure pulse filter is based on Common rules of short pulse bag filter developed a kind of new type, high efficiency bag filter. This series bag filter, the collection chamber fan blow and pulse injection, and many other advantages of dust collector, and lengthen the filter bag, give full play to the compressed air power blowing ash removal effect. Overcome the chamber blow soot cleaning strength is low, soot and dust filter pulse injection disadvantages at the same time, prevent the dust adsorption and out of control again, so as to improve the filtering speed, save the energy consumption of soot and prolong the service life of filter bag. By programmable controller of exhaust valve and pulse valve, discharge valve for automatic control, etc.
The bag filter is mainly composed of an upper box, a middle box, a lower box (ash bucket), a cleaning system and a ash discharging mechanism.
Product feature: 1.Parameters of large:
Suitable for all kinds of flue gas dust properties,maximum capacity can reach 110 x 104 m3/h.
2.High efficiency of dust collection:
Dust removal efficiency can reach 99.5-99.9% for dust concentration < 50 g/Nm3. 3.Good soot cleaning effect:
Injection device components have good aerodynamic characteristics; When the injection pressure is 0.20 to 0.25 MPa, to purify high dust concentration and moisture content of gas, there is still a very good soot cleaning effect. 4.Small area covering:
Filter bag length is 6m, filtration velocity can select between 1-1.2m/min, cover an area of an area smaller than conventional pulse bag filter and reverse blowing.
5.Advanced control technology:
Electric control system adopts advanced PLC, with on-line ash removal, offline ash removal, constant pressure difference dust cleaning, regular soot cleaning four kinds of optional function, and has the pressure, temperature detection system and manual control mode. High reliability, long service life and convenient for site adjustment. 6.Convenient operation and maintenance:
The filter bag mouth of elastic ring, can be directly embedded in the flower plate, seal and tear open outfit is convenient, improve the labor intensity of the operators.
1.Dust removal process:
Dust-laden gas enters the dust collector through the air inlet. The dust of the larger particles directly falls into the ash hopper. The gas containing the particulate dust passes through the filter bag. The dust is trapped on the outer surface of the filter bag, and the gas is purified and discharged by the induced draft fan. Into the atmosphere.
2.Ash removal process:
As the filtration work continues, dust particles adhering to the outer surface of the filter bag increase, and the dust collector operation resistance increases. The switching valve of a filter unit closes, the filter unit stops working, and the reverse-blowing compressed air reversely enters the filter unit. The dust on the outer surface of the filter bag is dropped, and then the valve plate is switched to open, the filter unit is again operated, and the dust is turned to the next filter unit. The entire cleaning process alternates with each filter unit.
