Abstract
Using compressed air as the bag-type dust collector and dust removal method of deashing power.Flue dust is to cause one of principal element of atmosphere pollution, the essential measure for reducing atmosphere pollution is exactly to reduce discharge of the harmful substance to air, national environmental standard tends to be stringent at present, the expense and requirement imposed to disposal of pollutants are also higher and higher, charges for disposing pollutants are exempted from, and discharge standard is required also than relatively low as long as the past is up to standard.It is a kind of using compressed air as the bag-type dust collector of deashing power, composition include：Head cover（8）, the head cover and clean room（7）Connection, the clean room and dust-removing box（6）Connection, the dust-removing box respectively with purified gas outlet（10）, dusty gas entrance（11）, stent（13）, ash bucket（12）Connection, the ash bucket and unloading valve（5）Connection.The present invention is applied to environmental protection.
Description
Technical field：
The present invention relates to a kind of using compressed air as the bag-type dust collector and dust removal method of deashing power, send elsewhere it is bright be applied to remove
Dirt field of environment protection.
Background technology：
Flue dust is to cause one of principal element of atmosphere pollution, the essential measure for reducing atmosphere pollution be exactly reduce harmful substance to
The discharge of air, at present national environmental standard tend to be stringent, to disposal of pollutants impose expense and require also higher and higher, the past
As long as up to standard exempt from charges for disposing pollutants, and discharge standard is required also than relatively low, the accessible gas of performance of deduster
Drag losses and efficiency of dust collection when amount, gas are by deduster are expressed, meanwhile, price, operation and the maintenance expense of deduster
Difficulty or ease with, service life length and operational administrative are also an important factor for considering its performance, but general filtrate at present
Efficiency of dust collection is not very high, and dedusting is not thorough and cost is higher,
Invention content：
The object of the present invention is to provide a kind of using compressed air as the bag-type dust collector and dust removal method of deashing power.
Above-mentioned purpose is realized by following technical scheme：
It is a kind of using compressed air as the bag-type dust collector of deashing power, composition include：Head cover, the head cover and clean room
Connection, the clean room are connect with dust-removing box, and the dust-removing box enters respectively with purified gas outlet, dusty gas
Mouth, stent, ash bucket connection, the ash bucket are connect with unloading valve.
It is described using compressed air as the bag-type dust collector of deashing power, dedusting filter is installed in the dust-removing box
Bag, the dedusting filtering bag connect with annular space injector, the annular space injector is connect with jet pipe, the jet pipe respectively with
Bag cage, electromagnetic impulse valve connection.
It is described using compressed air as the bag-type dust collector of deashing power,：One group of dedusting filtering bag hangs down with jet pipe
Directly it is mounted in dust cleaning case.
It is described using compressed air as the bag-type dust collector and its dust removal method of deashing power, it is described that its step are as follows.
（1）Dusty gas is by entering pulse dust collector under the gravitation of wind turbine, under the action of wind shield, air-flow is to upstream
Dynamic, stream reduces, and part large dust particle falls ash bucket since effect of inertia is separated, and dusty gas enters middle case filter bag
Filtration, purification, dust is delayed at the outer surface of filter bag, and purified gas enters upper body case through filter pocket mouths, arranged by air outlet
Go out.
（2）As filter bag surface dust is continuously increased, deduster inlet outlet pressure differential also rises therewith, when dust remover resistance reaches
During to setting value, control system sends out deashing instruction, and soot cleaning system is started to work.
Beneficial effects of the present invention：
The present invention releases compressed air using compressed air as deashing power, using pulse jet mechanism in moment, induces several times
Auxiliary air injects at a high speed filter bag, makes filter bag drastically bulging, reaches deashing purpose by impulsion and back draught, removes more thorough
Bottom.
The present invention is with ash-removal effect is good, purification efficiency is high, processing is large-minded, maintenance load is small, easy to operate, filter bag
Long lifespan, it is safe and reliable to operation the advantages that, and reformed from structure and on pulse valve, solve outdoor placement and compression
The problem of air source pressure is low.
Present invention can be widely used to building materials, electronics, chemical industry, environmental protection, the dust of each industrial circle such as mechanical processing remove
Dirt purifies, and efficiency of dust collection is very high, can generally reach 99%, can trap the fine dust particles that grain size is more than 0.3 micron, energy
Meet stringent environmental requirement.
Inventive can be stablized, the variation of the operating conditions such as processing air quantity, gas dust content, temperature, to sack cleaner
Dust removing effects influence little, dust processing is easy, is not required to water, so there is no sewage disposal or mud conditioning problem, receive
The dust of collection easily recycles.
Using flexible of the present invention, processing air quantity can be by hundreds of cubic meters per hour to tens of ten thousand steres per hour, can conduct
Indoor, neighbouring small unit is directly arranged in, may be alternatively configured large-scale dirt pocket, relatively simple for structure, running and comparing is stablized, just
Beginning investment is less, easy to maintain.
