Description

The sound wave ashing sack cleaner

Technical field

The utility model relates to a kind of sound wave ashing sack cleaner that utilizes sound wave ash cleaner, air quantity control butterfly valve and dust-removal cloth-bag that moisture height, viscosity dust big, fine size are gathered dust.

Background technology

Deduster commonly used at present has dry type and wet type two classes, wherein wet scrubber is a deduster commonly used with moisture film and gas cleaner, dry collector is a deduster commonly used with cloth bag and electric cleaner, wet scrubber is mainly used in the high dust of moisture is carried out dedusting, water source consumption is bigger, and recovery acquires a certain degree of difficulty.Dry collector mainly gathers dust at the dust below 7% to moisture, serves as main representative with electric cleaner and sack cleaner.Need be in the pelletizing production process with addition of the bentonite of different proportion, to improve qualification rate, the quality index that balling disk (-sc) goes out ball, bentonitic quality index directly influences the balling property of green-ball, because bentonitic moisture is higher, granularity is little, expansion multiple and colloid index are bigger, index is shown in Table 1 in detail.Water film type duster, the wet scrubbing machine dedusters of adopting when producing bentonite more, this type of deduster can consume a large amount of water sources when work, and the recovery difficult to the receipts dust is very big, even can not reclaim, bentonite in powder grit degree is less, in water, be in suspended state after meeting water, can not form precipitate and separate, dedusting sewage can only be effluxed.If adopt electric cleaner to gather dust, the higher dust of moisture is covered with electrode pad, influences efficiency of dust collection, reduces the electrode voltage grade, and working long hours to make electric cleaner frequently trip, shut down.If adopt the pulse jet sack cleaner that it is gathered dust, because the character of bentonite dust, pulse valve can not thoroughly be blown down dust from cloth bag, causes more and more so that influence the efficiency of dust collection of deduster that dust on the cloth bag accumulates, and the while also makes the life-span of deduster cloth bag reduce greatly.

Summary of the invention

For overcoming the deficiencies in the prior art, the utility model provides a kind of sound wave ashing sack cleaner simple in structure, that moisture height, viscosity dust big, fine size are gathered dust.

The technical scheme that the utility model adopted is: the deashing sack cleaner comprises acoustic wave soot blower, cloth bag and cloth bag framework, deduster air outlet, deduster casing, star-like unloading valve, receipts ash ash bucket, acoustic wave soot blower is positioned at the top of deduster casing, air inlet is connected with the receipts ash bucket, and the deduster air outlet is connected with deduster casing cloth bag top.

Deduster casing air inlet is provided with air inlet and regulates butterfly valve.

The deduster casing is as broad as long square casing.

After the air inlet adjusting butterfly valve that contains a wind process deduster of dust is adjusted to and moves the air requirement aperture, enter the deduster casing, the outside filtering type cloth bag will contain the powder filtering filtration in wind of dust, dust is attached on the cloth bag, through accumulation after a while, when pipeline pressure reaches setting value, acoustic wave soot blower is opened, the dust that adheres on the cloth bag is carried out rapping, and dust falls into the receipts ash ash bucket of deduster, by conveying equipment dust is transported.The first half that the secondary wind of cleaning enters the deduster casing from the cloth bag orifice plate enters the deduster air-introduced machine through the deduster air outlet by the airduct road and discharges through the blower fan chimney.The purge mode of being regulated butterfly valve control deduster by air inlet has two kinds, be that air inlet is regulated butterfly valve and opened acoustic wave soot blower can be implemented in the line deashing when normally open, also can when opening acoustic wave soot blower, close simultaneously, realize off-line ash-clearing by regulating butterfly valve from the moving control circuit of PLC.

The beneficial effects of the utility model are: utilize sound wave ash cleaner, air quantity control butterfly valve and dust-removal cloth-bag that moisture height, viscosity dust big, fine size are gathered dust, this deduster is not only simple in structure, maintenance is few, easy to use, and service life is longer.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.

Fig. 1 is the structure chart of the utility model specific embodiment;

Fig. 2 is the plane of the utility model specific embodiment;

Fig. 3 is the A-A profile among Fig. 2.

Among the figure: 1. acoustic wave soot blower, 2. cloth bag and cloth bag framework, 3. deduster air outlet, 4. cloth bag orifice plate, 5. manhole door, 6. deduster casing, 7. electromagnetic vibrator, 8. push-pull valve, 9. star-like unloading valve is 10. received ash bucket, and 11. air inlets are regulated butterfly valve, 12. the acoustic wave soot blower fixed mount, 13. box covers.

The specific embodiment

As shown in FIG., each casing of sound wave ashing sack cleaner is as broad as long square casing.Different according to the dust collection capacity size with air quantity, can there be a plurality of foursquare casings to be assembled into the whole body construction of a sound wave ashing sack cleaner.Among Fig. 2 and Fig. 3 three sound wave ashing sack cleaners that as broad as long square casing is formed, with each cabinet design is that foursquare advantage flue dust can be distributed to after entering casing around the casing very soon, can not cause flue dust to distribute because of the length-width ratio of casing is inharmonious and the dead angle occur, the top of each casing all is provided with an acoustic wave soot blower 1 simultaneously, square box can evenly distribute when deashing and carry out the sound wave rapping, can not produce the cloth bag and cloth bag framework 2 losts of life that the too drastic or local rapping effect of local rapping deficiency causes, the phenomenon that dust removing effects is bad.The fume ducts that enters each casing of sound wave ashing sack cleaner body all is independently; when changing the inspection of cloth bag or casing, can realize continuous dedusting, safeguard one by one; need not shut down whole sound wave ashing sack cleaner, only the air inlet control valve of the casing that needs need be safeguarded is closed and is got final product.After flue dust enters receipts ash bucket 10 by air inlet adjusting butterfly valve 11, carry out dedusting from deduster casing 6 through cloth bag and 2 pairs of flue dust of cloth bag framework, fall into behind dust process acoustic wave soot blower 1 deashing and receive ash bucket 10, clean air after the dedusting enters sound wave ashing sack cleaner upper part of body by cloth bag inside through cloth bag orifice plate 4, enter the air-introduced machine airduct road of sound wave ashing sack cleaner by the top deduster air outlet 3 of sound wave ashing sack cleaner, through the emptying of blower fan chimney.When reaching on the level-sensing device, the ash amount of receiving ash bucket 10 inside prescribes a time limit, star-like unloading valve 9 is opened, the ash of receiving 10 li in ash bucket enters ash-transmission system through push-pull valve 8 and star-like unloading valve 9, electromagnetic vibrator 7 is opened during this time, ash bucket is received in vibration, make the dedusting ash of receiving in the ash bucket all enter ash-transmission system, defeated ash can be realized the strength conveying with the strength delivery pump, also can realize the conveying of dedusting ash with scraper plate machine or screw(-type) feeder etc.

Though described embodiment of the present utility model in conjunction with the accompanying drawings, those of ordinary skill in the art can make various distortion or modification in the scope of described claim.
