Description
Technical field
The present invention relates to environmental improvement dedusting technology fields, more particularly to exempt from deashing anion pocket type smoke and dust purifier.
Background technique
Sack cleaner is a kind of dry type dust filtration device.Filter bag is using the filter cloth or nonwoven felt of weaving at utilization
The filtration of fabric is filtered dusty gas, and after dusty gas enters sack cleaner, particle is big, than great
Dust fall into ash bucket since the effect of gravity settles down, the gas containing relatively fine dust is when passing through filtrate, dust
By detention, it is purified gas.It is commonly used for the dust removal installation in large scale industry field.
For sack cleaner filtrate after a period of use, since sieving, collision, delay, diffusion, electrostatic are equivalent
It answers, filter bag surface has gathered one layer of dust, this layer of dust is known as bonding layer, and in motion process after this, bonding layer is at filtrate
Main filtration layer, by the effect of bonding layer, the biggish filtrate of mesh can also obtain higher filter efficiency.As dust is being filtered
Expect the accumulation on surface, the efficiency and resistance of deduster all accordingly increase, can be some when the pressure difference of filtrate two sides is very big
The tiny grit being attached on filtrate squeezes the past, declines dust collector efficiency.In addition, the resistance of deduster is excessively high to be made to remove
The air quantity of dirt system is remarkably decreased.Therefore, after the resistance of deduster reaches certain numerical value, timely deashing.It cannot be broken when deashing
Bad bonding layer, in case efficiency declines.
Anion generator is a kind of device for generating negative aeroion, and air negative ion generator is to utilize high-voltage corona
Anionic can promote health so as to improve air quality in increase air, be known as air " vitamin ".
Commonly used in the environment of life or small-sized purification air.And anion generator is applied on dust-extraction unit at present, mainly
It is to make its electrification by generating electrically charged anion and adsorb to dust particles, and then reunite and settle.But it is current negative
Ion electric field part-structure, Yi Fasheng arcing, the short circuit phenomenons such as make contact make negative electrode be difficult to stablize and maintain negative high potential, reduce
Ionizing efficiency causes free electron quantity to decline, and then affects clean-up effect.
Summary of the invention
The present invention overcomes the shortcomings of the prior art, the bag-type dust collecting equipment phase that will be applied in negative ion device and industry
In conjunction with deashing anion pocket type smoke and dust purifier is exempted from proposition, solves the problems, such as the deashing of exhaust dust device with bag, and improve bag
The service life and filter effect of formula dust-extraction unit.
The present invention is achieved through the following technical solutions.
Exempt from deashing anion pocket type smoke and dust purifier, including exhaust dust device with bag ontology, the exhaust dust device with bag sheet
Body is provided with filter bag, and the filter bag is connected with air inlet flue, and the inlet of the filter bag is provided with anion generator, described
Anion generator includes bracket, insulating sleeve, electrode needle, and the bracket is fixedly connected on the inlet of the filter bag, institute
It states bracket to be connected with insulating sleeve, high voltage cable is provided in the insulating sleeve, the high voltage cable is connected with described
Electrode needle；The electrode needle and filter bag entrance section are in 30-120 ° of angle, what the anion generator was used to generate
Anion is adsorbed on the dust particles of entrance and falls into it in filter bag, is produced by falling into the electrically charged particle agglomeration on filter bag
Inverse corona is given birth to shoot down the dust granule being attached on filter bag.
Further preferred structure, the filter bag are connected by air inlet with air inlet flue, the air inlet inner wall
On be provided with anion generator, the bracket is fixedly connected on the air inlet inner wall.
Further preferred structure, the filter bag inlet are provided with expansion cabinet, are provided in the expansion cabinet negative
Ion generator.
Further, the anion generator is uniformly distributed with array.
Further preferred structure, the electricity grade pole needle and filter bag entrance section are in 65 ° of angle.
Further, the exhaust dust device with bag is external-bay precipitator or inward flow filtration-type bag filter.
The present invention is generated compared with the existing technology to be had the beneficial effect that.
Anion fine-purification generating device is installed additional in exhaust dust device with bag entrance, it, can electricity when flue gas passes through electrode perimeter
A large amount of free electrons can be dissociateed under electric field action from gas, free electron can be dissipated by negative electrode repulsion is adsorbed in dust
On grain, the dust particles of electrification can adsorb the uncharged dust particles in periphery, reunite, and increase particle size and shorten
Settling height.Reduce certain bag type filter device load, while the aggregation of the charged particle thing intercepted by bag filter
The aggregation that will form negative electrical charge will form inverse corona when reaching certain aggregate amount, and effect can make the dust of cloth bag surface
Layer loosen simultaneously fall off, play the role of spontaneous deashing, also, in filter bag the thicker position for needing deashing of dust stratification its generation energy
Measuring the bigger inverse corona that can generate falls dust stratification by itself impact, and the bonding layer position less in filter bag dust stratification, electrically charged grain
Son is relatively fewer, and the electric energy of generation is not enough to generate inverse corona, will not shoot down the bonding layer ash at this, in turn can be in filter bag
Bonding layer is protected.
Cloth bag hardware and cabinet, integral ground, guarantee section charged particle thing touch hardware and cigarette
Charge effectively can be imported into the earth when road inner wall, it is ensured that safety in utilization.
It, which compares the advantages of conventional electric bag composite construction, is, the present apparatus by the way that anion generator is arranged in filter bag entrance,
And the charge for making needle angle control in pole ensure that dust carries in a certain range can finally be gathered in cloth bag surface, need filter bag
It wants the thick-layer dust stratification position of deashing to be shot down by inverse corona that charged dust particle generates is spontaneous, while protecting the dust stratification of bonding layer, make
It will not be shot down, so that the operation that special ash disposal is carried out to filter bag type cleaner is eliminated, it is multiple using the present apparatus and pocket type
It closes that after-purification effect is more preferable, can be achieved that automatic ash removing, operating cost are lower, is a kind of convenient and practical novel energy-saving environment-friendly skill
