Description
Technical field
The present invention relates to a kind of exhaust dust device with bag that is used for the atmosphere inhalable particulates removing.
Background technology
Along with greatly developing of economy, more and more to the pellet that discharges in the air, these pellets are huge to human body harm, particularly the fine particle of diameter below 2.5 μ m is easy to enrichment toxic heavy metal, acidic oxide, organic pollution, bacterium and virus especially, and is difficult to get rid of after entering human body.But because the fine particle volume of diameter below 2.5 μ m is little, in light weight and quantity is many, conventional at present centrifugal dedusting, dust removal by filtration and electric precipitation all are difficult to prove effective.
Summary of the invention
The object of the invention provides a kind of good to the fine particle removal effect of diameter below 2.5 μ m, the sound wave auxiliary composite bag type dust remover that life of bag filter is long.
The present invention adopts following technical scheme for achieving the above object:
The present invention includes housing, card is set in the housing, housing is divided into dedusting chamber and clean room space; Several through holes are set on the card, connect a filter bag on each through hole respectively, dedusting is provided with air inlet on the chamber; Set out gas port on the clean room space; The bottom in dedusting chamber is provided with ash bucket; It is characterized in that in the dedusting chamber sonic horn being set, described sonic horn is between filter bag and air inlet.
Reasonablely be: between above-mentioned sonic horn and the filter bag porous barrier is set, an end of porous barrier is connected with the inwall in dedusting chamber.
Reasonablely be: the percent opening of above-mentioned porous barrier increases from top to bottom gradually.
Reasonablely be: the length of above-mentioned filter bag is 2/3～3/4 of housing height.
Reasonablely be: the length of above-mentioned porous barrier is longer than the length of filter bag.
The present invention utilized sound wave that the fine particle of diameter below 2.5 μ m carried out preliminary treatment before ash-laden gas enters sack cleaner, its reunion is formed enter filter bag again after large-size particles is rolled into a ball, and reached the effect that removes to fine particle.Porous plate is cut down the influence of dust collection by sound wave unit to the bag-type dusting unit, the air-flow that enters the bag-type dusting unit is entered simultaneously from filter bag side and filter bag bottom, reach air-flow and evenly distribute, avoid the import flue gas, prolong the service life of filter bag directly the washing away of filter bag.
The present invention adopts technique scheme, compared with prior art has following advantage:
1, the present invention is provided with sonic horn between porous barrier and housing, short grained fine particle can be agglomerated into to enter filter bag after large-size particles is rolled into a ball, and has improved the filtration result of filter bag to ash-laden gas.
2, porous barrier of the present invention two ends have only an end to be connected with housing, the dusty gas that enters like this in the housing enters filter bag through a sonic horn reunion back part through the aperture on the porous barrier, another part gas enters filter bag through the space between porous barrier and the housing, make like this and all be used to remove dusty gas along the transversely arranged filter bag of housing, and be not only that several filter bags near porous barrier participate in removing dusty gas, prolonged the service life of filter bag.
3, the present invention the through hole that is provided with on the porous barrier be according on dredge down close mode and arrange, purpose is to allow the easy separated into two parts of dusty gas, because the through hole on top is more sparse, so arrived in the bottom of porous barrier through the gas after reuniting, a part is passed porous barrier and is entered filter bag, another part is walked around in the filter bag that enters behind the porous barrier away from porous barrier, has prolonged the service life of filter bag.
4, the length of filter bag of the present invention is 2/3～3/4 of housing height, and purpose is to make that the dusty gas after reuniting can better be removed, and strengthens the efficient that removes, and improves removal effect.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:
As shown in Figure 1, the present invention includes housing 7, card 9 is set in the housing 7, housing 7 is divided into dedusting chamber 10 and clean room space 5; Several through holes are set on the card 9, connect a filter bag 4 on each through hole respectively, air inlet 1 is set on the dedusting chamber 10; Set out gas port 6 on the clean room space 5; The bottom in dedusting chamber 10 is provided with ash bucket 8; It is characterized in that being provided with in the dedusting chamber 10 sonic horn 2, described sonic horn 2 is between filter bag 4 and air inlet 1.
Reasonablely be: between above-mentioned sonic horn 2 and the filter bag 4 porous barrier 3 is set, an end of porous barrier 3 is connected with the inwall in dedusting chamber 10.The percent opening of above-mentioned porous barrier 3 increases from top to bottom gradually.The length of above-mentioned filter bag 4 is 2/3～3/4 of housing 7 height.The length of above-mentioned porous barrier 3 is longer than the length of filter bag 4.
The present invention has a shell 7, and housing 7 is split into and is divided into dedusting chamber 10 and 5 two parts of clean room space, connects air inlet 1 on the dedusting chamber 10, connects gas outlet 6 on the clean room space 5, and ash bucket 8 is positioned at the below of housing 7.The sound unit and the bag-type dusting unit that are used for the fine particle reunion are horizontally disposed in housing, sonic horn 2 is concordant with the top of filter bag 4, and the length of filter bag accounts for 2/3～3/4 of dust removing units height.The top of filter bag is a clean room space 5.Between sound wave particle agglomeration unit and bag-type dusting unit porous barrier 3 is set, dividing plate length exceeds filter bag length.Dividing plate is taked rare close perforate mode that increases progressively gradually down, thereby forms a plurality of gas distributions zone from top to bottom.
The course of work of the present invention is as follows: ash-laden gas enters the acoustic agglomeration unit from air inlet 1 level, fine particle is reunited under the effect of sonic horn 2, then under the effect of porous barrier 3, a fine particle part enters the bag-type dusting unit from the horizontal side of filter bag 4, and another part enters the bag-type dusting unit from the bottom.Dusty gas separates through the dedusting of two unit, and grit falls into ash bucket 8 through behind the deashing process, and clean gas enters clean room space 5,6 discharges from the gas outlet at last.
