Description
Technical field
The novel large scale industry factories and miness dedusting technology that relates to of this use is a kind of big air quantity combined type filter cartridge dust remover specifically.
Background technology
One of main method of dust removal by filtration formula industrial dedusting, the visible whole filter cartridge dust remover of unit that has only small dimension on the market far can not adapt to large enterprise's large tracts of land (5000m such as power plant, smeltery, steel mill now
2More than) the dedusting demand.
Summary of the invention
The purpose of this utility model provides a kind of result more scientific and reasonable with regard to being to overcome above-mentioned weak point of the prior art, and it is big to have filter area, and operation, easy to maintenance is applicable to big air quantity combined type filter cartridge dust remover.
The purpose of this utility model can realize by following measure:
The novel big air quantity combined type filter cartridge dust remover of this use comprises a plurality of deduster unit that are provided with parallel way, each unit is separated into air-purifying chamber and dust settling filter chamber by diaphragm plate, be provided with dust storage chamber in bottom, dust settling filter chamber, the ash hole that is positioned at each dust storage chamber below is connected with conveying worm respectively by unloading valve; The dust settling filter chamber of each unit is connected with the dust-contained airflow air inlet by the reduction of speed air channel; In the dust settling filter chamber of each unit, be provided with the filter cylinder of many group Chalk-dust filterings, this filter cylinder bottom surface sealing, the upper end is fixed on the dividing plate and with air-purifying chamber by connector and sealing strip and is connected; The sidewall of the air-purifying chamber of each unit is provided with air outlet, and air outlet is equipped with lift valve; Above the air-purifying chamber of each unit, be provided with blowing device; Described blowing device links to each other with the air-purifying chamber inner chamber by the winding-up pipe.
The quantity of the winding-up pipe described in the utility model is identical with the filter cylinder number.Described blowing device comprises gas bag and the winding-up pipe that is connected by pulse valve.
The novel operation principle of this practicality is as follows:
After dust-contained airflow enters the reduction of speed air channel by air inlet, air-flow is decelerated, and even distribution of quilt enters the dust settling filter chamber of each dust removing units, more coarse grained dust disengaging this moment air-flow is deposited in the dust settling filter chamber, the less dust of granularity is blocked on the outer surface of filter cylinder when then seeing through filter cylinder with air-flow, purified gas enters the unit air-purifying chamber after discharged by air outlet; For removing the dust that gathers on filter cylinder surface, can send instruction closing unit air outlet lift valve by control system, open simultaneously pulse valve in the unit in order, compressed air in the gas bag is sprayed at a high speed via the winding-up pipe, induce the surrounding air that is several times as much as injection tolerance to enter the filter cylinder cavity simultaneously, form high velocity air from inside to outside, the dust that accumulates in the filter cylinder outside is blown off by high velocity air and be deposited in the dust settling filter chamber, emit by ash-removing valve at last, fall dust by conveyer and discharge.Each unit by by control system according to programmed program deashing successively, do not need to close whole dust-removal system.
Deduster of the present utility model can make up arbitrarily according to the actual needs of engineering, not only applicable to large enterprise's large tracts of land (5000m such as smelting furnace, kiln, steel mills
2More than) the dedusting demand, also can satisfy＞18000 meters
2The demand of above power plant's dedusting.
The utility model not only has the more scientific and rational advantage of structure compared to existing technology, and it has that filter area is big, the pressure loss is little, ash-removal effect is good main thing, and the characteristics of easy operating, maintenance.
