Description

Off-line ash-clearing on-bne repair rotating pulse spraying filter bag type deduster
Technical field
The present invention relates to a kind of off-line ash-clearing on-bne repair rotating pulse spraying filter bag type deduster, specifically being used for the main casing profile is the sack cleaner of cylinder, belongs to the environmental protection equipment technical field.Be widely used in metallurgy, electric power, chemical industry, build the smoke and dust treatment in the fields such as work.
Background technology
Having volume of smoke at metallurgy, electric power, chemical industry, in building the field such as work need to administer, and these need to adopt pulse jet filter bag type dedusters usually.And domestic and international conventional pulse jet filter bag type deduster generally has that structure is numerous, resistance than high, floor space large, the in/out air tube difficult arrangement and possess off-line ash-clearing can't on-bne repair etc. deficiency and drawback.
In order more effectively to administer flue dust, must thoroughly solve deduster the problems referred to above, make the advantages such as dust removal device standby " structure is the simplest, resistance is minimum, off-line pulse jetting deashing, on-bne repair change filter bag, take up an area economize, arrange nimble ".
Summary of the invention
The present invention proposes a kind of off-line ash-clearing/maintenance rotating pulse spraying filter bag type deduster, especially possesses the deduster of " structure is the simplest, resistance is minimum, off-line pulse jetting deashing, on-bne repair change filter bag, take up an area economize, arrange nimble ".
For achieving the above object, technical solution of the present invention is that off-line ash-clearing on-bne repair rotating pulse spraying filter bag type deduster, be applicable to metallurgy, electric power, chemical industry, build the smoke and dust treatment in the fields such as work; It is the bag dust collector of cylinder that the present invention has adopted the main casing profile; Comprise the cylindrical shape main casing, the ash bucket bottom arranges discharge apparatus, filter chamber, card, filter bag, annular clean air chamber in main casing; In main casing, center also is provided with fixed gas storage bag, in fixed gas storage bag bottom, some quantity pulse valves, compressed air distributor, rotating driving device and some rotating pulse spraying pipes is set, and is provided with the partition plate structure of some peripheries with sealing device above the rotation impulse injection tube; Each pulse blowing pipe both sides is provided with the off-line ash-clearing cover; Card (5) is equipped with at (4) top in filter chamber; By arranged in concentric circles, filter bag (6) is arranged between card (5) and filter chamber (4); Card (5) top is annular clean air chamber (19); The protruding rib of some quantity is set as spacer assembly on card, protruding rib, with together with some division boards and injection tube, is separated into the annular clean air chamber of deduster the fan-shaped independent enclosure space of some quantity; The air outlet place corresponding in each fan-shaped clean air chamber is provided with the air-out valve; Set out airduct in the middle inside of main casing (or outer periphery).
Beneficial effect of the present invention is: simple, compact and reasonable for structure; Can realize the duster pulse off-line ash-clearing, ash-removal effect is good; Can realize duster pulse off-line maintenance (namely changing filter bag), but yet on-bne repair does not affect dust pelletizing system and normally moves yet; Can realize that several pulse valves complete the deashing of whole filter bags; Can effectively reduce the deduster setting height(from bottom); Can reduce the resistance of deduster and damage, resistance is little, reduces the operation power consumption, and floor space is little, and the steel consumption is low, and filtration velocity can improve under identical air quantity.
