  • pulses Periodically, at the time of blocking the flow of dirty gas or air, pulses produce compressed air through impulse tubes into the cavity of the frame filter elements.
  • a feature of the known solution is that the filter elements are made with open ends. During the passage of a pulse of compressed air, a pneumatic shock occurs on the shell, which leads to its expansion and, as a result, the destruction of the accumulated pollution on the shell.

  • a high pressure receiver is used, from which compressed air is supplied through pipelines and valves to the impulse tubes. Since a large number of cavities of the filter elements are simultaneously processed by pulses and this processing is carried out in open cavities, then, naturally, the power of the receiver and the volume should be large. This is because in order to clean the shells of the filter elements, it is necessary to create such a pressure that would ensure the stretching of the shell or the formation of wave shifts on it. Shell deformation leads to destruction accumulated pollution on it.

  • the frame filter element open at two ends is an open system. Therefore, when applying a pulse of compressed air, most of this flow will simply pass from one end to the other, and only a small part of the flow will create some pressure on the shell. In order for the shell deformation to be significant, it is necessary to create a very powerful impulse, which is obtained only when using large high-pressure receivers. Most of the compressed air is wasted and unproductive, wasting energy.
