Detailed description of the invention
Double combination type dust pelletizing system of the present utility model comprises cyclone dust collectors and fiber bag precipitator, see Fig. 1, show cyclone dust collectors wherein, it comprises shell 101, described shell 101 supports by many supporting legs 102, upper spacer 106 and lower clapboard 104 is provided with in described shell 101, the top of described upper spacer 106 forms exhaust chamber 111, the top of described exhaust chamber 111 is provided with exhaust outlet 112, shell 101 between described upper spacer 106 and lower clapboard 104 is provided with air inlet 103, described air inlet 103 is connected to total inlet pipe, will the flue gas of dedusting be needed to introduce, described lower clapboard 104 is provided with multiple opening, respectively Open Side Down, and extension is provided with ceramic cyclone body 105, each ceramic cyclone body 105 is made up of pottery and is both ends open shape, wherein, an air funnel 107 is equipped with in each ceramic cyclone body 105, the lower end of described air funnel 107 is stretched out from ceramic cyclone body 105, upper end extends to upper spacer 106 and is communicated to exhaust chamber 111, thus, flow downward from ceramic cyclone body 105 after flue gas enters, exhaust chamber 111 is oppositely entered again by air funnel 107, and discharge from the exhaust outlet of exhaust chamber 111, roundabout reflexed is carried out owing to obtaining dust in flue gas, dust is wherein filtered.
Wherein, the outer rim of each described air funnel 107 is provided with flow deflector 108, to lead to the gas flowing in ceramic cyclone body 105, preferably, described flow deflector 108 is spiral helicine flow deflector, the lower end of described shell 101 is provided with the ash bucket 109 of back taper, and the lower ending opening of described ash bucket 109 is provided with openable lid 110.
As can be seen here, these cyclone dust collectors can utilize the principle of centrifugation to carry out work, ash-laden gas enters distribution of gas room by total inlet pipe, enter the annular space between ceramic cyclone body and air funnel subsequently, flow deflector more can make gas become circular motion from rectilinear motion, and the overwhelming majority of swirling eddy is downward twist from cylinder along cyclone body, and the ash bucket towards taper flows, ash-laden gas produces centrifugal force in rotary course, and grit density being greater than gas gets rid of to barrel.Grit is contacting with barrel, just lose inertia force and lean on the momentum of entrance velocity and downward gravity to enter ash bucket along wall to falling into ash discharging hole, when rotating the outer rotational gas flow arrival cone lower end position declined, because namely the contraction of cone from bottom to top continues at tornadotron axis direction shape flowing (i.e. pure qi (oxygen)) of spinning with same direction of rotation, air funnel in ceramic cyclone body enters exhaust chamber, discharged by exhaust outlet, therefore, cyclone dust collectors simple structure, investment cost is few, little being convenient to of floor space and locus is installed, but cyclone dust collectors are collected limited to fine dust, therefore a tablecloth sack cleaner is also arranged in the outlet of cyclone dust collectors.
See Fig. 2, show fiber bag precipitator of the present utility model, described fiber bag precipitator comprises housing 12, the bottom of described housing 12 is provided with smoke inlet 16, described smoke inlet 16 is communicated to the exhaust outlet 112 of cyclone dust collectors, flue gas is introduced in housing 12, the dividing plate 18 of a lateral arrangement is also provided with in described housing 12, housing 12 top is separated out upper box 20 by described dividing plate 18, the sidepiece of described upper box 20 is provided with exhanst gas outlet 19, described dividing plate 18 is provided with multiple through hole, each through hole is provided with filter cloth bag 17, thus, after flue gas enters housing 12, upper box is entered by multiple filter cloth bag 17, discharge from exhanst gas outlet 19 again, dust is filtered cloth bag 17 and filters.
Wherein, described smoke inlet 16 and exhanst gas outlet 19 are equipped with breather valve, to control turnover and the flow of gas.
Wherein, described housing 12 is supported by the support 11 of lower end, and the bottom of housing 12 is formed with the conically shaped 13 of back taper, described smoke inlet 16 can be located at the top of conically shaped 13, and preferably, described smoke inlet 16 is tangentially introduced from conically shaped 13, thus flue gas is when entering, in conically shaped 13, form the wind direction of spiral, flow velocity is reduced further, realizes the precipitation of larger particles dust and fall.
Wherein, the lower ending opening of described conically shaped 13 is connected with dust-collecting cylinder 14, and the dust collected in conically shaped 13 falls into dust-collecting cylinder 14 from opening, is convenient to pipette and change, dismountable coupling assembling 15 is provided with, to provide fast and convenient replacing and installation between described conically shaped 13 and dust-collecting cylinder 14.
Wherein, described filter cloth bag 17 is tubular and is made up of medium alkali fiber cloth, and the through hole of dividing plate 18 is fixed on by connector in its upper end, and lower end is closed by medium alkali fiber cloth.
For realizing the deashing of filter cloth bag 17, the upper box 20 of described housing 12 is also provided with a ventilating opening, and described ventilating opening is connected with high-pressure air source by pipeline, is provided with electromagnetic impulse valve 21 between described ventilating opening and high-pressure air source.
The outside of described housing 12 is also provided with stair 22, safeguards easily to provide and clears up.
Thus, in use, after ash-laden gas is entered by the smoke inlet on conically shaped top, air-flow upwards flows the utility model, flow velocity reduces, part big dust particle falls into conically shaped because the effect of inertia is separated, and enters dust-collecting cylinder, and other ash-laden gas is with the filtration of crossing filter cloth bag, flue dust is delayed at the outer surface of filter cloth bag, gas after filtration enters upper box through filter pocket mouths, is discharged by exhanst gas outlet, thus realizes the filtration of other granule dust.
Along with the prolongation of filtration time, the dust layer in filter cloth bag is constantly long-pending thick, and filtration resistance constantly rises, and when resistance reaches certain value, carries out deashing by deashing device.
Concrete deashing process is: first, and air valve is closed, and filtered airflow is blocked, then electromagnetic impulse valve is opened, the compressed air of high-pressure air source, with extremely very brief time undergoes rapid expansion in upper box, pours in filter cloth bag, filter cloth bag is out of shape and produces vibration, and under the effect of washing away at inverted draft, the dust be attached on filter cloth bag outer surface is stripped and falls into ash bucket, and after deashing, electromagnetic impulse valve is closed, air valve is opened, and can recover filtration condition in time.
Fall into ash bucket through the dust filtered and deashing work is retained down, then concentrate discharge by the ash-discharging device of grey quarrel.
As can be seen here, the utility model has the advantage of:
1, structure is simple, easy to operate, realizes effective filtration of size particles dust;
2, filter fully thoroughly, economical and practical, effectively meet dust emission standard.
It is evident that, above description and record be only citing instead of in order to limit disclosure of the present utility model, application or use.Although described in an embodiment and be described in the drawings embodiment, but the utility model do not limit by accompanying drawing example and describe in an embodiment as the optimal mode thought at present to implement the specific examples of instruction of the present utility model, scope of the present utility model will comprise any embodiment of description and the appended claim fallen into above.
