The specific embodiment
In order to deepen understanding of the present invention and understanding, below in conjunction with the drawings and specific embodiments, the present invention will be described in detail and introduction.
Embodiment 1: referring to Fig. 1, a kind of Environmental-protection dust removal device, described Environmental-protection dust removal device comprises upper box, middle casing 4, ash bucket parts, filters cloth bag 5, dust removing system and auxiliary equipment, described filtration cloth bag is arranged in middle casing, the bottom of middle casing is provided with dust removing system, wherein, upper box comprises clean air chamber, access cover, pure qi (oxygen) outlet; Middle casing comprises porous plate, air inlet, access door, and the ash bucket parts comprise ash bucket casing, observation panel; Dust removing system comprise unload grey dead lock 7, apparatus for ash 6 is scraped in revolution; Described auxiliary equipment comprises guardrail and ladder 1 etc., described dust-contained airflow is casing 4 from air inlet tangentially enters, the dust that a part is more big and heavy and the dust granules of coalescence fall into the ash bucket bottom along the casing barrel, when part fine dusts has been filter cloth bag 5 with the air-flow drift, filtration is captured, clean air enters into upper box through filter cloth, then discharges from the pure qi (oxygen) mouth.
Embodiment 2: referring to Fig. 1, as a modification of the present invention, described ash bucket casing adopts flat grey bucket structure.Dust removing system is by scraping plate mechanism and unload grey dead lock and form.Fall the dust in ash bucket, force to scrape cinder-discharging port by scraping hawk, then discharge by discharge apparatus, so just destroyed the condition of dust knot arch, both made dust be unlikely the knot arch, reduced again the height of complete machine, make dust discharge smoothly deduster.Operation principle is as follows: in system design adopted contrary air-flow blowback.The high pressure deashing air-flow that utilizes high pressure positive blower to produce and filtered airflow opposite direction, by filter cloth, make its lip-deep dust releasing, fall into ash bucket.This purge mode distributes more even at whole filter bag overdraught, air-flow is not moisture, and the filter bag wear rate is low, can extend life-span of the filter bag and not affected by makings, not need to provide compressed air, can independently form dust pelletizing system, but structure is slightly large, and filtration velocity is relatively low.Consider the characteristics of this area high humidity, therefore select contrary air-flow blowback.Traditional purge mode is continuous deashing winding-up, and this mode energy waste is serious, and the design adopts differential pressure to control.When resistance of the filter bag reaches setting value, soot cleaning system starts deashing work, and when resistance of the filter bag drops to setting value by contrary air-flow deashing, soot cleaning system quits work.Like this, both can make deduster work in normal range of resistance, can reduce again the energy consumption of deashing.
Filtering cloth bag is the important component part of deduster, the dust humidity causes dust at filter bag surface adhesion caking, dust remover resistance is increased, soot cleaning system can't blow off dust, in design, the coated filter material of water is scolded in employing, makes it existing good gas permeability, can avoid again the filter bag that there was dampness in the air causes to block phenomenon.
During deduster work, dust-contained airflow tangentially enters casing from air inlet, and under the effect of gravity and centrifugal force, the dust that a part is more big and heavy and the dust granules of coalescence fall into the ash bucket bottom along the casing barrel, when part fine dusts arrives filter cloth with the air-flow drift, filtration is captured.Clean air enters into upper box through filter cloth, then discharges from the pure qi (oxygen) mouth.Along with the dust of filter bag surface trapping is more and more, dust remover resistance is increased, for by draught control in limited range, utilize the anti-blow cleaning dust system, by winding-up and the high pressure draught of filtered airflow opposite direction, dust is shaken off down from filter bag.Dust under shaking off falls into ash bucket, by scraping hawk and unloading grey dead lock it is discharged outside dust collector box body.
The chain realization of deduster and wind net automatically controlled and manually controls.1) power-up sequence: discharge apparatus → scraping machine structure → wind host blower fan.2) shutdown sequence: wind host blower fan → scraping machine structure → discharge apparatus.
