Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

The pulse back blowing device 10 is used for communicating with the dust chamber 210, and the pulse back blowing device 10 is used for reversely blowing air to the filter element 60 installed in the dust chamber 210; the pressure sensor 30 is disposed in the dust chamber 210. The differential pressure sensor 40 is respectively communicated with the dust chamber 210 and the cleaning chamber 220; the differential pressure sensor 40 has a first pressure measuring head extending into the dust chamber 210 and a second pressure measuring head extending into the clean chamber 220, thereby facilitating the pressure measurement of the dust chamber 210 and the clean chamber 220. The pulse back-blowing device 10, the pressure sensor 30 and the differential pressure sensor 40 are respectively electrically connected with the controller.
It can be understood that, during operation, the blowback device 10 draws air from the external environment into the dry separator 200 and blows the air under a certain pressure toward the filter element 60, so that the filter element 60 filters and removes dust, and the dust is blown into the dust chamber 210, thereby achieving the purpose of cleaning the filter element 60. When the pressure of the air flow blown toward the filtering member 60 is greater than the adhesive force of the dust attached to the filtering member 60, the dust can be smoothly blown and removed from the filtering member 60 by the blowback air flow, but when the pressure of the air flow blown toward the filtering member 60 is less than or equal to the adhesive force of the dust attached to the filtering member 60, the dust cannot be removed from the filtering member 60 by the air flow, so that the dust blocks the filtering member 60.
Alternatively, filter element 60 may be, but is not limited to, any one of a filter plate, filter bag, filter cartridge, and the like. For example, the filter member 60 in the present embodiment is a filter plate.
In summary, the technical solution of the present embodiment has the following advantages: the intelligent blowback pressure monitoring system 100 of the above scheme is applied and equipped in the dry separator 200, and is used for monitoring the pressure difference between the dust chamber 210 and the clean chamber 220, and ensuring that the dust on the filter element 60 can be cleaned under various working conditions. Specifically, during normal operation, the pulse back-blowing device 10 blows air in a reverse pulse manner to the filtering element 60 according to the initial set parameters, but when the monitoring value of the differential pressure sensor 40 rises at a certain moment, which indicates that the current pulse airflow cannot effectively blow off the dust on the filtering element 60, the differential pressure sensor 40 feeds back a signal to the controller 20, and the controller 20 adjusts parameters of the pulse interval, pulse width, airflow pressure, and the like of the pulse back-blowing device 10, so as to effectively clean the dust attached to the filtering element 60, and the adjustment can be performed according to the dust blocking condition on the filtering element 60, that is, according to the dynamic changes of the monitoring signals of the differential pressure sensor 40 and the pressure sensor 30, so as to ensure that the system is in an optimal operation state while preventing the filtering element 60 from being blocked by the dust, so that the cleaning efficiency is high, the cleaning effect is good, the whole process is automatically monitored, and automatically adjusted to an optimal back-blowing ash cleaning state, the whole process does not need manual intervention, and the dry separator 200 can continuously and normally work.

Therefore, the system can dynamically track each monitoring parameter value from the source when the system starts working, so that the blocking condition of the filter element 60 is accurately judged, each parameter of the back-blowing airflow is regulated, and the back-blowing airflow is ensured to have a good dust removing effect on the filter element 60.

The compression container 12 is used to blow the blowback air flow discharged from the pulse valve 11 toward the filter member 60 at a certain pressure.
Optionally, the pressurized container 12 is a gas bag.
In addition, on the basis of the above embodiment, the pulse back-blowing device 10 further includes a flow distribution plate 13, the flow distribution plate 13 is provided with a plurality of flow distribution holes, and the flow distribution plate 13 is disposed between the air outlet of the compression container 12 and the filter element 60. The area of the arrangement of the plurality of shunting holes on the shunting plate 13 is equal to or larger than that of the filtering piece 60, so that dust in all areas on the filtering piece 60 can be removed simultaneously by the back-blowing airflow, and the purpose of removing the dust more quickly and effectively is achieved.

The intelligent back-blowing pressure monitoring system according to claim 4, wherein the pulse back-blowing device further comprises a proportional pressure regulating valve, the proportional pressure regulating valve is disposed in the air intake pipeline, and the proportional pressure regulating valve is located between the pneumatic control valve and the compression container.
6. The intelligent blowback pressure monitoring system of claim 2, wherein the blowback gas flow emitted from the compression container has a flow path, and the pressure sensor is at an end of the flow path.
7. The intelligent blowback pressure monitoring system of any one of claims 1 to 6, further comprising a control panel, wherein the control panel is electrically connected to the controller.
8. The intelligent backblowing pressure monitoring system according to claim 7, further comprising an alarm, wherein the alarm is electrically connected to the control.
9. A monitoring method for operation of the intelligent blowback pressure monitoring system according to any one of claims 1 to 8, comprising the steps of:
the controller controls the pulse back blowing equipment to blow air to the filter in a reverse direction;
when the differential pressure sensor monitors that the differential pressure value between the dust chamber and the clean chamber rises, the controller controls the pulse interval, the pulse width and the airflow pressure of the back blowing airflow of the pulse back blowing equipment;
when the pressure sensor monitors that the stable value of the pressure value in the dust chamber is set to be within a normal range, the controller controls the pulse back-blowing equipment to keep the current working parameters until the back-blowing cleaning operation of the filter piece is completed.
10. A dry separator comprising an intelligent blowback pressure monitoring system as claimed in any one of claims 1 to 8.
