Description
Technical field:
The present invention relates to a kind of dust arrester installation of control atmosphere pollution, more specifically to a kind of washing type bag dust-collector.
Background technology:
The present invention is mainly used in improvement may be discharged into the central gas that contains the solid granular floating dust of atmosphere.Existing dust arrester installation is mainly, blowback bag filter and impulse bag dust-precipitator, and its groundwork principle is:
The blowback bag filter is divided into air inlet or following two kinds of citation forms of air inlet from structure; On the mode of filtering, be divided into inward flow filtration-type or two kinds of basic skills of outside filtering type again, no matter form with which kind of form or mode, but its operation principle is essentially identical, generally be to combine by a chamber to a plurality of filtrations, during work, the gas that contains flue dust distributes through tapered pipeline (tapered pipeline in succession simultaneously each filter chamber) under the effect of air-introduced machine or air blast and enters the filter chamber, the bigger dust of quality is when entering the filter chamber, because of the long-pending increase of duct cross-section, the reduction of dust rate of flow of fluid and being deposited in the grey storehouse of filter chamber bottom, remaining flue gas still moves to filter cloth under the drive of air-flow, the dust of the overwhelming majority is blocked in this side of flue gas under the filtration of filter cloth, stick on the filter cloth, enter in the atmosphere through the clean gas after filtering.When the amount of dust acquired a certain degree on sticking to filter cloth, cleaner cut out the wherein air inducing valve of a filter chamber automatically, and this chamber temporarily quits work.The dust that will stick on the filter cloth with reverse air-flow blows off then, and after stopping a period of time, open the air inducing valve, and make this chamber from newly entering duty, the process of deashing turns to next chamber of filtering then, carry out deashing one by one, the deashing up to all filter chambers finishes.
The impulse bag dust-precipitator roughly also is divided into two kinds on structure: a kind of is the air box impulse bag-type dust-precipitator, and a kind of is long bag off-line bag filter, and they are structurally had any different slightly, but operation principle is basic identical.Great majority all are that the chamber by a plurality of filtrations combines, and dusty gas is under the effect of air-introduced machine.Enter the filter chamber by air intake passage (air intake passage in succession simultaneously each filter chamber), because of the increase of air channel area, the bigger dust of some quality can't continue to move upward and is deposited in the following grey storehouse when air velocity reduces flue dust when entering the filter chamber.Remaining flue gas still moves to filter cloth under the drive of air-flow, and the flue dust of the overwhelming majority are blocked in this side of flue gas under the filtration of filter cloth, stick on the filter cloth.When the amount of dust on the filter cloth acquires a certain degree, cleaner cuts out the wherein air inducing valve of a filter chamber automatically, this chamber temporarily quits work, utilization sprays in the extremely short time through the gases at high pressure (0.5-0.8MPa) of overcompression, and induce a large amount of secondary gas flows to enter in the filter bag, rightabout shake when making filter bag in the extremely short time, produce with work, under the effect of shake and back draught, the dust that sticks on the filter cloth is shaken off, and after stopping a period of time, open the air inducing valve of this chamber, make this chamber from newly entering duty, the process of deashing turns to next chamber of filtering then, carry out deashing one by one, the deashing up to all filter chambers finishes the operation that goes round and begins again.
But above-mentioned prior art has following major defect: if bigger dust granules is when entering the filter chamber, make the flow velocity decline (under the equal gas flow condition) of gas owing to the long-pending increase of gas duct cross-section, when the gravity of dust granules acts on greater than the kinetic energy that moves upward, dust granules will fall into grey storehouse automatically, this illustrates that also continuation is smaller or light and bigger kinetic energy is arranged to the dust granules of filter cloth direction (top) motion, and finally those dust will be stopped by filtrate and adhere in the above.When stopping filtration work and carry out deashing, no matter be to carry out deashing with blowback or injection method, the dust that sticks on the filter cloth will be shaken off and be clashed into, most of muffins are formed tiny particle once more towards broken, rapidly gasification and become the compressive state disperse (we all know general knowledge in the filter chamber under the effect of deashing air-flow, that be exactly light weight and little particle under the interference of air-flow, easily form flying dust, and occupy to fall in the air and not for a long time), have only the block dust of a small amount of cake to satisfy the grey storehouse of falling into of landing condition.Hui Cang of each filter chamber or admission line owing to these dust-precipitators links again, what we stopped is one or several filter chamber, and still working in other filter chamber, that will cause the chamber of other work to collect the secondary flue gas that these form with negative pressure state under the effect of " malleation " air-flow, that is to say that this is by the chamber of deashing, the dust of being shaken off satisfies the grey storehouse of falling into of decline condition in a small part, other dust will be gasified again, bringing other operating room into sticks on its filtrate or spreads in the thick fog shape in the space of this filter chamber, under the effect of air inducing air-flow, caught by filtrate once more when waiting this chamber to devote oneself to work, come to this and circulating, up to dust form enough thickness on the filter cloth and also during at deashing also not by air-flow towards broken, forming could be by real time filter cloth clearly in the time of satisfying the piece that falls into grey storehouse.
So in sum, the common working condition of existing cleaner is, dust thickens on the filter cloth, cause the increase of equipment running resistance, (more obvious in the electric furnace metallurgical dust is administered, the bag filter that has is after continuously through tens hours work, and deduster performs practically no function, almost do not have any treatment effect directly to cause the decline of device processes air quantity and the rising of blower fan total head, at this moment must stop deduster and carry out the deashing processing, and this will cause former pollution sources to begin to pollute).The rising of blower fan total head will make a large amount of tiny dust granules directly pass filter cloth and enter atmosphere, cause efficiency of dust collection to descend, and the general who has surrendered causes the deficiency of former design air flow under the air quantity, can not handle the flue dust of pollution sources fully, and the cleaner serious waste the energy.Excessive in order to alleviate the said equipment resistance, our common way is the frequency that strengthens the power of filter area, increase air-introduced machine (what have can increase 2-3 air quantity doubly, and how much how many air quantity increases is just meaning air-introduced machine power increases) or increase deashing; Yet the increasing of filter area, just meaning the increase of device fabrication investment, the deashing frequency is too much meaning the reduction in equipment consumable accessory life-span again, and it will directly cause the reliability reduction of equipment and the increase of maintenance work, so this is a kind of mode of curing the symptoms, not the disease, need thoroughly to improve.
