Reverse-blowing detection device for self-cleaning type filter element and fan

Abstract

The invention relates to the technical field of filtering, in particular to a reverse-blowing detection device for a self-cleaning type filter element. The reverse-blowing detection device comprises a detection channel; a manmade dust sending pipe for artificially generating dust and a filter element section for filtering dust in air are arranged on the detection channel in sequence; a reverse-blowing device for reversely blowing the filter element of the filter element section is arranged on the filter element section; a first differential pressure transmitter for measuring the differential pressure between the front end and the rear end of the filter element section is also arranged on the detection channel; the dust is sent out through the manmade dust sending pipe, the reverse-blowing device is used for reversely blowing the filter section, and then, the differential pressure after reverse-blowing is detected through the differential pressure transmitter, so that the performance recovery situation of the filter element after the self-cleaning type filter element is reversely blown can be clearly analyzed. Through stimulation of the working conditions of the self-cleaning type filter element, corresponding data is obtained to help an enterprise to improve the quality and the performance of the filter element.

Description

[0001] technical field [0002] The invention relates to the technical field of filtration, in particular to a self-cleaning filter element blowback detection device and a fan. Background technique [0003] In order to reduce energy consumption and save the use cost of filter elements, most large air filter elements use self-cleaning filter elements. The indicators of flow rate and pressure drop are restored, and the purpose of prolonging the service life of the filter element is achieved. [0004] However, it is not known how the performance of the filter element will recover after backflushing. In order to ensure the stability of the equipment, the user can only obtain data through long-term use under actual working conditions or replace it regularly based on experience. In many cases, the performance of the filter element is still very high Well, resulting in an increase in cost. The effect on the filter element production unit is to achieve the purpose of optimizing fi...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: In order to solve the problem that the performance recovery of the existing self-cleaning filter element can not be known after backflushing, the present invention provides a self-cleaning filter element backflushing detection device, which can be detected by artificial dust detection. The dust pipe emits dust, and the blowback device blows back the detected filter element, and then detects the pressure difference after blowback through the first differential pressure transmitter, so that the performance recovery of the self-cleaning filter element after blowback can be clearly analyzed Happening
