Abstract:
     An energy accumulator is installed between the blower and the filter, and between the accumulator and the exit of filter chamber are connected a reverse blowing valve and a spray nozzle. Behind the blower is provided a cooler for the purified gas. The reverse blowing by the accumulted energy is completed in three steps: 1. Increasing gas pressure in the accumulator, 2. Reverse blowing, and 3. dust removing through contraction of the bags. During the first step the blower draws puritied gas from the main pipeline and sends it into the accumulator. And then the "reverse blow" is accomplished by adjusting the reverse blowing valve to inject the gas held in the accumulator into the chamber through a nozzle, forming a pressure difference in the reverse direction, thus causing the bags to contract and the dust to be discharged from them.
