Offline high pressure pulse bag filter uses advanced three-state off-line cleaning mechanism, to avoid dust “re-absorption”, a thorough cleaning, reliable work. Offline high pressure pulse bag filter imported solenoid valves, diaphragm service life of wearing parts high; the use of advanced three-state off-line cleaning mechanism, to avoid the dust “re-absorption”, a thorough cleaning, reliable; design a single The new chamber jet cleaning technology to reduce the number of pulses of dust than conventional valve 6-20 times. Offline high pressure pulse jet bag filter is widely used in building materials, metallurgy, chemical, foundry and other industries dust control and material recovery. Filter cleaning mechanism using SCM automatic control, both the timing and manual two kinds of control are optional. Efficient three-state filter cleaning mechanism may be a high concentration of dust (dust concentration to allow entrance 1000g / Nm) to replace the original secondary dedusting, lower investment costs. Advanced spring up ring type fastening and pocket bag cage welding line to produce high-quality bag cage products, not only to ensure effective sealing of the bag, and extend the life of the filter bag
