Description
Technical field
The utility model relates to a kind of exhaust dust device with bag that is used for removing the air-flow pellet, and especially a kind of acoustic agglomeration composite bag type dust removing device belongs to the technical field that pollution control equipment is made.
Background technology
Pellet in the atmosphere is huge to human body harm, PM
2.5(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 enters human body and be difficult to get rid of.But because PM
2.5Volume little, in light weight and quantity is many, at present conventional single centrifugal dedusting, dust removal by filtration and electric precipitation all is difficult to prove effective.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of acoustic agglomeration composite bag type dust removing device is provided, and it can remove the PM in the dust-contained airflow efficiently
2.5
According to the technical scheme that the utility model provides, described acoustic agglomeration composite bag type dust removing device comprises dusty gas surge chamber, acoustic agglomeration chamber, sack cleaner, ash bucket, sonic generator, D power-like amplifier and signal generator; The bottom of described dusty gas surge chamber is provided with the ash-laden gas import, described dusty gas surge chamber links to each other with an end of the acoustic agglomeration chamber of horizontal positioned, the inwall of described acoustic agglomeration chamber is provided with sonic generator, described sonic generator links to each other with the output of D power-like amplifier, and the input of described D power-like amplifier links to each other with signal generator; The other end of described acoustic agglomeration chamber links to each other with sack cleaner, and described sack cleaner bottom is provided with ash bucket.
The number of described sonic generator is an even number, and described sonic generator adopts arranged in arrays.
Advantage of the present utility model: the utility model utilized sound wave to PM before ash-laden gas enters sack cleaner
2.5Carry out preliminary treatment Deng molecule, its reunion is formed enter sack cleaner again after large-size particles is rolled into a ball, reach effectively removing fine particle.The structure of acoustic agglomeration chamber and sack cleaner is relatively independent, and both effects all can be brought into play to greatest extent.Reunion chamber horizontally disposed increased the reunion effect, promoted efficiency of dust collection.The employing of D power-like amplifier has increased electro-acoustic conversion efficiency, has reduced the dedusting energy consumption.
Description of drawings
Fig. 1 the utility model structural representation.
The specific embodiment
As shown in Figure 1: a kind of acoustic agglomeration composite bag type dust removing device comprises dusty gas surge chamber 2, acoustic agglomeration chamber 3, sack cleaner 4, ash bucket 5, chimney 6, sonic generator 7, D power-like amplifier 8 and signal generator 9; Described dusty gas surge chamber 2 bottoms are provided with ash-laden gas 1 import, described dusty gas surge chamber 2 links to each other with acoustic agglomeration chamber 3 one ends of horizontal positioned, described acoustic agglomeration chamber 3 sidewalls are provided with sonic generator 7, described sonic generator 7 links to each other with the output of D power-like amplifier 8, and the input of described D power-like amplifier 8 links to each other with signal generator 9; The other end of described acoustic agglomeration chamber 3 links to each other with sack cleaner 4, and described sack cleaner 4 links to each other with chimney 6 by flue, and described sack cleaner 4 bottoms are provided with ash bucket 5.
Described sonic generator 7 numbers are even number, and described sonic generator 7 adopts arranged in arrays.After the operating frequency of signal generator 9 is determined, calculate wavelength at this operating frequency lower plane sound wave, change sonic generator 7 spacings of symmetric arrangement, the sonic generator 7 of two symmetries is installed on the integral multiple position of half-wavelength, in acoustic agglomeration chamber 3, form standing wave.
During dedusting: ash-laden gas 1 is introduced dusty gas surge chamber 2, after described ash-laden gas 1 slows down, enter acoustic agglomeration chamber 3 in dusty gas surge chamber 2 cavitys from the connector of dusty gas surge chamber 2 and acoustic agglomeration chamber 3.Ash-laden gas 1 according to the flow of dusty gas 1, is determined the cross section and the total length of acoustic agglomeration chamber 3 by the acoustic agglomeration chamber 3 of horizontal positioned, and the time that ash-laden gas 1 is stopped in acoustic agglomeration chamber 3 is 3s～8s.Utilize signal generator 9 to produce the sinusoidal signal of 20Hz～20KHz, D power-like amplifier 8 carries out power amplification with the sinusoidal signal that described signal generator 9 produces, produce the high strong sound wave of 160dB, the high strong sound wave that produces is by sonic generator 7 outputs, and the standing wave of driving a vehicle in the cavity of acoustic agglomeration chamber 3.When ash-laden gas 1 passes through acoustic agglomeration chamber 3 in the time of 3s～8s, under the high strong sound wave effect of sonic generator 7 outputs, bump, make the minute dust particle aggregation.Ash-laden gas 1 after the reunion enters sack cleaner 4, and the clean gas after the filtration is discharged from chimney 6, and the filter dirt of generation is discharged from ash bucket 5.
