Abstract
The utility model relates to an ash hopper pressure-relief dust removing and recycling device for preventing the ash from spreading outside during the pressure-relief process of a middle ash hopper of dry dust catcher for blast furnace gas, comprising a release cap (1), a release short pipe (2) and a middle ash hopper (3). The utility model is characterized in that: a filtration short pipe (4) is arranged over the middle ahs hopper (3); a nitrogen supply pipe (5) and a baffle plate (6) are arranged in the filtration short pipe (4); the baffle (6) is provided with a round hole (7); a filter cloth bag (8) is arranged along the round hole (7); easy-to-detach flanges (9) and (10), (11) and (12) and (13) and (14) are respectively arranged between the filtration short pipe (4) and the release short pipe (2), in the middle of the release short pipe (2), and between the filtration short pipe (4) and the middle ash hopper (3). The utility model can reduce the ash content in the blast furnace gas, thereby achieving good effect of protecting the health of operators and the surrounding environment.
Description
Technical field
The dedusting retrieving arrangement that dust loose outward when the utility model related to the release of the middle bucket of a kind of blast furnace gas nonaqueous dust cleaner.
Background technology
Middle ash bucket plays a part to store in blast furnace gas nonaqueous dust cleaner, the cooling down high-temperature gas ash, the internal reservoir ash is delivered to the defeated ash discharging system of scraper plate machine carries out the humidification outward transport by diffusing pressure release when unloading ash.Because the former defeated middle ash bucket pressure height in the grey process that unloads, need when putting ash to reduce gas pressure in the middle ash bucket by opening bleeder, previously used bleeder is not established any dedusting retrieving arrangement, a large amount of blast furnace dusts are along with coal gas is directly discharged during pressure release, not only influence the healthy of operation personnel, simultaneously surrounding environment is caused severe contamination.
Summary of the invention
The purpose of this utility model can reduce the ash bucket pressure release dedusting retrieving arrangement of dust content in the coal gas when providing the ash bucket release of a kind of centre.The technical solution of the utility model is: the utility model includes and diffuses cap, diffuses short tube and middle ash bucket, feature is above middle ash bucket, be provided with one and filter short tube, in filtering short tube, be provided with towards nitrogen tube, in filtering short tube, a dividing plate is set, have circular hole on the dividing plate, install to filter cloth bag, filter short tube and diffuse between the short tube, diffuse in the middle of the short tube and filter between short tube and the middle ash bucket and be respectively equipped with easy-to-mount flange along circular hole.
The utility model can reduce dust content in the coal gas, has played good effect to the protection operator are healthy with the protection surrounding environment.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1, diffuse cap, 2, diffuse short tube, 3, middle ash bucket, 4, filter short tube, 5, towards nitrogen tube, 6, dividing plate, 7, circular hole, 8, filter cloth bag, 9, flange, 10, flange, 11, flange, 12, flange, 13, flange, 14, flange.
Embodiment
With reference to accompanying drawing, the utility model includes and diffuses cap 1, diffuses short tube 2 and middle ash bucket 3, feature is above middle ash bucket 3, be provided with one and filter short tube 4, in filtering short tube 4, be provided with towards nitrogen tube 5 and dividing plate 6, have circular hole 7 on the dividing plate 6, install along circular hole 7 and filter cloth bags 8, filter short tube 4 and diffuse between the short tube 2, diffuse in the middle of the short tube 2 and filter between short tube 4 and the middle ash bucket 3 and be respectively equipped with easy-to-mount flange 9 and 10,11 and 12 and 13 and 14.
Using method of the present utility model is: during release, open and diffuse valve, the coal gas that carries dust filters through filtering cloth bag 8 when effluxing, coal gas is discharged through diffusing short tube 2, dust is assembled attached to filtering on the cloth bag 8, after release finishes, opens nitrogen big gun valve through carrying out blowback towards nitrogen tube 5, reclaim in the ash bucket 3 in the middle of blowback, shake are laid and fallen into attached to the dust on the filter cloth, and by the airtight humidification outward transport of defeated ash discharging system.
Claims (2)
