The working principle of the flat bag filter : the working state of the filter, the dust entering the upper space of the filter room tangentially. Under the action of centrifugal force, large particles and condensed dust particles spiral along the wall toward the filter room bag, especially small particles Scattered in the ash hopper gap. Purified air is sucked from the inlet and outlet of the fan in the atmosphere through the clean room of the bag guide on the wall panel.
Working principle of flat bag dust collector Under regeneration conditions, the dust on the surface of the filter bag and the resistance of the filter bag gradually increase with the filter conditions. When blowing into the resistance risk control system, the pressure difference transmitter interface is connected to the pipe before and after the filter. The signal air will start working automatically.
In the case that the nozzle bag of the jet weapon is fully guided into, and the air pressure of the filter is blocked, the vibration caused by the bag material is changed, the dust is removed, and the filter bag is rotated once. When the resistance of the filter bag is lower than the limit, blow The air mechanism automatically stops working.
The flat bag type dust collector saves the power of the explosion-proof dryer, reduces the soot blowing, is not restricted by the air source conditions, has fewer wearing parts, simple maintenance and reliable operation. The long filter bag can make full use of space and occupy a small area.
★. Under the action of the induced draft fan, the dust-containing gas enters the filter room from the ash bucket (or the open flange at the lower part), and a part of the larger dust particles directly falls into the ash bucket or ash bin.
★ 、 The remaining dust-containing gas is filtered by the filter bag, then passed through the mouth of the bag to the clean room, and finally discharged into the atmosphere by the fan, while the dust adheres to the outer surface of the filter bag;
★ 、 As the dust on the surface of the filter bag increases continuously, the resistance of the equipment also increases. When the set value is reached, the time relay (or differential pressure controller) outputs a signal.
★, the program controller starts to work, turn on each pulse valve in turn, and let the compressed air through the nozzle to blow the dust out of the filter bag,
★, the filter bag suddenly expands under the action of high-pressure air, and the dust attached to the bag surface is quickly separated from the filter bag and falls into the ash hopper (or ash bin) under the action of reverse airflow, and the dust is finally discharged by the flap valve.
★, the spray only cleans the filter bags one by one, and the other filter bags still filter normally, which does not affect the dust removal of the whole machine.
