Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

It should be understood that the terms "upper", "lower", "left", "right", "middle" and "one" used herein are for clarity of description, and are not intended to limit the scope of the invention, but rather the scope of the invention.

As shown in fig. 1, the utility model discloses a cyclone, including casing 1, be equipped with air inlet, gas outlet 11, whirlwind pipeline 4 and blowback mechanism 5 on the casing 1, be equipped with filtering mechanism and ash bucket 3 in the casing 1, ash bucket 3 is located filtering mechanism's below for the absorbent dust of filtering mechanism can directly fall into in the ash bucket 3. The air outlet 11 is positioned above the filtering mechanism, the back blowing mechanism 5 is arranged opposite to the filtering mechanism, the air inlet is positioned between the ash barrel 3 and the filtering mechanism, the cyclone pipeline 4 is arranged outside the shell 1 in a surrounding manner, and the outlet of the cyclone pipeline 4 is communicated with the air inlet. The width of the cyclone pipeline 4 is gradually increased from the inlet to the outlet end, so that the wind speed is gradually reduced, large-particle dust is automatically settled in the cyclone pipeline, and a detection window is arranged on the cyclone pipeline, so that the dust in the cyclone pipeline can be conveniently observed and cleaned. The waste gas is discharged from the gas outlet 11 after passing through the cyclone pipeline 4 and the dust removal mechanism in sequence, so that the dust in the waste gas is fully absorbed.

As shown in figure 1, the filtering mechanism comprises a plurality of filtering materials 2 which are parallel to each other and are obliquely arranged in the shell 1, the inclination angle alpha of the filtering materials 2 can be 5-15 degrees, the oblique arrangement increases the filtering area of the filtering materials, and the waste gas treatment capacity and efficiency are improved. The end of giving vent to anger of every filter media 2 passes through air outlet channel 12 and gas outlet 11 intercommunication, and the one end that the end was kept away from to give vent to anger of filter media 2 passes through wedge 13 and casing 1 inner wall fixed connection, the filter media's of the slope setting of being convenient for fixing.

The back-blowing mechanism 5 comprises a plurality of air blowing nozzles 51 which are arranged corresponding to the filter materials 2 one by one, and the air blowing nozzles 51 are communicated with the air outlet channel 12 and are opposite to the air outlet end of the filter materials 2. Each blowing nozzle 51 is correspondingly provided with a blowback valve 52, and the blowback valve 52 controls the operation or closing of the corresponding blowing nozzle 51. The blowback valve 52 can be a pulse valve, the pulse valve controls the operation of the blowing nozzle 51 to blow or close according to the air pressure difference at the two ends of the feedback filter material of the barometer, whether the adsorbed dust on the filter material exceeds the range is judged according to whether the air pressure difference is in the preset range, and if the adsorbed dust on the filter material exceeds the range, the blowing nozzle operates to blow to the air outlet end of the filter material, so that the dust on the filter material is blown down to fall into the ash bucket 3, and the filtering and dedusting effect of the filter material is ensured.
