Abstract
The invention relates to a blast furnace gas dust removal device. The blast furnace gas dust removal device comprises a dust removal tank, wherein an injection chamber, a dust removal chamber and a dust hopper chamber are arranged in the dust removal tank. A gas outlet is arranged on the top of the dust removal tank. A dust removal tank top part aside the gas outlet is provided with a draught fan. Injection pipes are arranged in the injection chamber. Multiple nozzles are arranged at low parts of the injection pipes. An upper separator plate and a lower separator plate are fixed in the dust removal chamber. Multiple filter cylinders are uniformly arranged between the upper separator plate and the lower separator plate and each one of the filter cylinders is arranged below the corresponding one of the nozzles. A side of a dust removal tank part between the injection chamber and the dust removal chamber is provided with a gas inlet. The gas inlet is provided with a gas regulating valve. The bottom of the dust removal chamber is connected to the dust hopper by a flange. A dust collection hopper is arranged in the dust hopper chamber. An opening of the dust collection hopper is communicated with the bottom of the dust removal chamber. The blast furnace gas dust removal device has the advantages that the filter cylinders have long service lives and are convenient for maintenance and replacement; and the bottom of the dust removal chamber is connected to the dust hopper chamber by the flange and the dust collection hopper is dismountable so that washing is easy and use is convenient.
Description
Technical field
The present invention relates to a kind of cleaning apparatus, relate in particular to a kind of dedusting of blast furnace gas device.
Background technology
Usually the bag-type dust collector in the blast furnace gas dry dusting device is used comparatively generally, and filter bag is fixed in the dust-removing box mostly, and filter bag is easy to damage under conditions such as high temperature, HS, so to the maintenance of filter bag, to change be very much inconvenient; In addition, the dust after the dedusting directly leads to grey small room usually, is discharged by grey small room again, and the time has been grown, and does not often clean grey small room, causes the ash bucket chamber interior walls to adhere to sticking foreign material easily, stops up ash output hole, finally causes whole cleaning apparatus cisco unity malfunction.
Summary of the invention
The purpose of this invention is to provide a kind of dedusting of blast furnace gas device, the filter cylinder long service life of this device, replacing are conveniently.
The technical scheme that the present invention adopts is:
The dedusting of blast furnace gas device comprises dust-removing box, is provided with winding-up chamber, dust settling chamber and grey small room in the said dust-removing box; Said dust-removing box top is provided with the air outlet, and other dust-removing box top, said air outlet is equipped with induced draft fan, the indoor winding-up pipe that is provided with of said winding-up; Said winding-up pipe is provided with gas bag, and said gas bag is connected with pulse valve one end through pipeline, the said pulse valve the other end and winding-up pipe coupling; Said winding-up pipe has a plurality of nozzles, and said dust settling chamber internal fixing has upper spacer and lower clapboard, evenly is placed with a plurality of filter cylinders between said upper spacer and the lower clapboard; Corresponding filter cylinder below said each nozzle; Dust-removing box one side between said winding-up chamber and the dust settling chamber is provided with inlet mouth, on the said inlet mouth Air-regulating valves is installed, and said dust settling chamber bottom is connected with grey small room through flange; The indoor flue-dust retainer that is provided with of said ash bucket, the opening of said flue-dust retainer communicates with the dust settling chamber bottom.
Said nozzle and filter cylinder number average are 5-15.
Advantage of the present invention: the filter cylinder long service life, maintenance, replacing are conveniently; The dust settling chamber bottom is connected with grey small room through flange, and this dismountable flue-dust retainer cleans easily, and is easy to use.
