Big and heavy dust and the dust granules of coalescence fall into hopper bottom along casing barrel, and a part of fine dusts arrived with air-flow drift
During filter cloth bag 5, be captured filtration, and the air of cleaning enters into upper box through filter cloth, then discharges from clean QI KOU.
Embodiment 2: see Fig. 1, as a modification of the present invention, described ash bucket casing uses flat grey bucket structure.
Dust removing system is made up of with unloading ash dead lock scraping plate mechanism.Fall the dust in ash bucket, forced to scrape cinder-discharging port by scraping hawk, then
Discharged by discharge apparatus, destroy the condition of dust knot arch, both made dust be unlikely knot arch, and reduced again the height of complete machine
Degree, makes dust discharge cleaner unit smoothly.Operation principle is as follows: have employed inverse air-flow blowback in system designs.Utilize high-pressure blast
The high pressure deashing air-flow that machine produces passes through filter cloth with filtered airflow is in opposite direction so that it is the dust releasing on surface, falls into ash bucket.
This purge mode is more uniform at whole filter bag overdraught distribution ratio, and air-flow is the most aqueous, and filter bag wear rate is low, can extend the filter bag longevity
Life is not affected by makings, it is not necessary to provides compressed air, can independently constitute dust pelletizing system, but structure is slightly larger, filtration velocity phase
To relatively low.In view of the feature of this area high humidity, therefore select inverse air-flow blowback.Traditional purge mode is the spray of continuous deashing
Blowing, this mode energy waste is serious, and the design uses differential pressure control.When resistance of the filter bag reaches setting value, soot cleaning system
Starting deashing work, when resistance of the filter bag drops to setting value by inverse air-flow deashing, soot cleaning system quits work.So, both may be used
Make cleaner unit work in normal range of resistance, the energy consumption of deashing can be reduced again.
Filter cloth bag is the important component part of cleaner unit, and dust humidity causes dust in filter bag surface adhesion and to lump,
Making dust remover resistance increase, dust cannot be blown off by soot cleaning system, in the design, uses the coated filter material scolding water, is allowed to existing
Good breathability, can avoid again the filter bag that there was dampness in the air causes to block phenomenon.
During cleaner unit work, dust-contained airflow tangentially enters casing, under the effect of gravity and centrifugal force, one from air inlet
The dust granules dividing more big and heavy dust and coalescence falls into hopper bottom along casing barrel, and a part of fine dusts is with air-flow drift
During to filter cloth, be captured filtration.The air of cleaning enters into upper box through filter cloth, then discharges from clean QI KOU.Along with filter bag
Surface trapping dust get more and more, make dust remover resistance increase, in order to by draught control restriction in the range of, utilize back-blowing
Soot cleaning system, by jetting, dust is shaken off down from filter bag by the high pressure draught in opposite direction with filtered airflow.Under shaking off
Dust falls in ash bucket, by scrape hawk and unload ash dead lock discharge it outside dust collector box body.
