The specific embodiment

Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.

A kind of pulse self-cleaning, air cleaning equipment comprises support 1, and said support 1 top is equipped with casing device, and the below is provided with the dust retracting device; Said casing device inside is provided with filter, pulse backblowing device and control system, and said dust retracting device comprises takes out grey blower fan 2 and the grey funnel 3 of collection, and the grey funnel of said collection 3 upper ends are connected with ash-collecting pipe 15, the lower end with take out grey blower fan 2 and link to each other; Said casing device comprises air-purifying chamber 5, and the front end of said air-purifying chamber 5 is provided with air outlet 4, and the rear end is equipped with rain cover 11, and said rain cover 11 inner tops are provided with illuminating lamp 10; Said filter is installed in the inside of air-purifying chamber 5, and it comprises V-type air cleaner 17 and bracing frame 16, and said V-type air cleaner 17 1 ends are installed on the bracing frame 16 through fastening bolt 18, and the other end links to each other with ash-collecting pipe 15; Between said V-type air cleaner 17 and the ash-collecting pipe 15 sealing gasket 19 is installed; Said pulse backblowing device is installed on the air-purifying chamber 5; It comprises Venturi tube 14, winding-up pipe 6 and blowback house steward 8; Said winding-up pipe 6 is provided with the spray orifice 20 of a row more than six or six; Said blowback house steward 8 links to each other with winding-up pipe 6 through pulse backblowing valve 7, and said blowback house steward 8 is provided with electromagnetic valve component 9; Said control system is installed on the rain cover 11, and it comprises continuous control terminal case 12 and differential pressure transmitter 13, and said control terminal case 12 links to each other with electromagnetic valve component 9.
