Abstract
The invention discloses a multitube impact dust removing device with a centrifugal fan and a dust removing method. A traditional dust remover needs to prevent gas in a bag house from being cooled below a dew point, particularly the use should be paid more attention at a negative pressure, as air inleakage often exists in a casing of the dust remover and the gas temperature of the bag house is lower than the dew point, so that a filter bag is damp, dust is stickily, not loosely, adhered on the filter bag; an eyelet of fabric is blocked off, so that the deashing is invalid, the pressure drop of the dust remover is too large, the dust remover cannot be continually operated, and paste bags are generated in certain dust removers to cause the failure of the dust removing function of the dust removers. The multitube impact dust-removing device with the centrifugal fan comprises the centrifugal fan (1), and is characterized in that the centrifugal fan is connected with an upper box body (2), the upper box body is connected with a lower box body (3), and the lower box body is connected with a support frame (4). The device disclosed by the invention is applied to dust-removing equipment.
Description
technical field:
the present invention relates to a kind of with centrifugal blower Multi-pipe impact dust arrester and dust collection method, the present invention is also applicable to the industrial circles such as mine, chemical industry, coal building materials, metallurgy, electric power.
background technology:
the equipment that dust is separated from flue gas is deduster or cleaner.The accessible gas flow of performance, the gas of deduster are expressed by drag losses during deduster and efficiency of dust collection.Meanwhile, the price of deduster, operation and maintenance cost, service life length and the difficulty or ease of operational administrative be also consider the key factor of its performance.Traditional deduster will prevent gas to be cooled to below dew point in bag indoor, particularly uses under negative pressure and more should note.Bleed because its shell usually has air; make bag room gas temperature lower than dew point; filter bag will make moist; cause dust not to be loosely, but be attached on filter bag stickyly, fabric perforations is blocked; deashing is caused to lose efficacy; make deduster pressure drop excessive, cannot continue to run, bag is stuck with paste in some generations cannot dedusting.|
summary of the invention:
the object of this invention is to provide a kind of with centrifugal blower Multi-pipe impact dust arrester and dust collection method.
above-mentioned object is realized by following technical scheme:

the described dust collection method with centrifugal blower Multi-pipe impact dust arrester, after the method comprises the steps: that dusty gas is entered by entrance, by dust block board, larger dust granules is stopped that lower backwardness is removed, less dust granules together enters header along with air-flow, at this moment dusty gas is through ajutage, with higher speed from shower nozzle ejection, impact liquid level has clashed into a large amount of foams and water droplet, reaches with this object purified air.Air after purification is under the effect of blower fan, arranged by air outlet (or centrifugal fan air outlet) by the first water fender and the second water fender, water droplet contained in purified gas is by first, second water fender is removed, the water of Purge gas is after the use regular hour, owing to needing containing a large amount of dust in water to change, when changing water, by electric pushrod, the piston outside discharge outlet is mentioned, sewage containing a large amount of dust is discharged through discharge outlet, after sewage is substantially drained, Water level controller controls the magnetic valve be located on water inlet manifold and opens (pressure of supply water is 0.5 ~ 2kg/c ㎡), water is sprayed by the flooding nozzle being located at dust collector box body bottom by water inlet pipe, bottom half is rinsed well, then piston puts down by electric pushrod, discharge outlet is closed, the water surface in casing rises, when the water surface rises to dedusting desired height, Water level controller Controlling solenoid valve is closed, and allow water interrupt, water unnecessary in casing is discharged by overflow pipe, now deduster can enter duty.
beneficial effect of the present invention:
1. the present invention is by centrifugal blower and duster body integration, thus decreases the auxiliary equipment of user, and reduces the equipment resistance of dust pelletizing system; Tank gage shifted out body, increase and observe visor and overflow pipe, both improve the stability of unit running, and facilitated operation again.
2. the present invention is mainly used in non-fiber, non-corrosiveness, temperature not higher than the purified treatment of the dusty gas of 120 DEG C, is also applicable to the industrial trades such as mine, chemical industry, coal building materials, metallurgy, electric power simultaneously.
3. the present invention is relatively simple for structure, small investment, and efficiency of dust collection is higher, can remove small particle diameter dust, and can remove a part of pernicious gas simultaneously, as dust removal integrated in flue gas desulphurization etc.
4. after dusty gas of the present invention is entered by inlet duct, by dust block board, larger dust granules is stopped that lower backwardness is removed, less dust granules together enters header along with air-flow, at this moment dusty gas is through ajutage, spray from shower nozzle with higher speed, impact liquid level has clashed into a large amount of foams and water droplet, reaches with this object purified air.
