Abstract

The utility model relates to an improved apparatus for dust removal, purification and recovery of electrolytic cell, and provides a device for dust removal, purification and recovery of electrolytic cell that can save energy and prolong the service life of the electrolytic cell. The utility model comprises a hopper (5) of a feed down pipe (4) and an electrolytic cell (3), and is characterized in that a gas trap hood (8) positioned on the bottom of the hopper and also above a fire hole (6) is connected with a reactor (10) through a flue (9). The hopper (5) is connected with a bag filter (14) through a branch pipe smoke exhaust (12) and a main pipe smoke exhaust (13), and the bag filter (14) is connected with a chimney (17) through an air duct (15) and an induced draft fan (16). The bottom of the bag filter (14) is connected with an alumina bin (2) through a return product chute (11) and a material hoist (1).

Description

Electrolyzer udst separation retrieving arrangement

Technical field:

The utility model relates to the improvement of udst separation retrieving arrangement structure of the electrolyzer of electrolytic aluminum.

Background technology:

The flue gas that existing electrolyzer udst separation retrieving arrangement produces aborning, by 44 gas collections of the gas skirt on the electrolyzer through the smoke evacuation house steward 43 (it is provided with the absorption reaction storehouse that lays fresh aluminum oxide) to sack cleaner 42, the flue gas up to standard of generation drains in the atmosphere through induced draft fan 41, chimney 40; The aluminum fluoride that reclaims through returning charge chute 45, material elevator 48, aluminum oxide warehouse 49, Conveying Chute 47 to hopper 46.But have following shortcoming: the flue gas that electrolyzer produces is in gas skirt 44, and gas skirt 44 structures are unreasonable, and it is bigger to leak out, and therefore, needs powerful induced draft fan 41 of configuration and big sack cleaner 42 etc., causes the waste of the energy; In addition,, increased the cycle index of aluminum oxide, caused the granularity of aluminum oxide to reduce (promptly having reduced the quality of production), quickened the wearing and tearing of equipment, reduced service life of equipment because of air quantity is bigger; Be on smoke evacuation house steward 43, to dispose the absorption reaction storehouse again, make it complex structure.

The utility model content:

The utility model is exactly serious, the baroque problem of energy dissipation, equipment attrition that solves current electrolysis groove udst separation retrieving arrangement, but a kind of save energy is provided, improves service life of equipment, electrolyzer udst separation retrieving arrangement simple in structure.

The utility model adopts following technical scheme: the utility model comprises hopper, the electrolyzer with feed opening, its structural feature is that the top corresponding to pinkeye, the bottom of hopper are provided with gas skirt, gas skirt links to each other with reactor by flue, hopper links to each other with sack cleaner by smoke evacuation arm, smoke evacuation house steward, sack cleaner links to each other with chimney by airduct, induced draft fan, and the bottom of sack cleaner links to each other with aluminum oxide warehouse by returning charge chute, material elevator.

The beneficial effects of the utility model:

1. save energy:

Because above corresponding to pinkeye, the bottom of hopper is provided with gas skirt, the flue gas that just makes electrolyzer and produced focuses on gas skirt at an easy rate, and discharges by the induced draft fan of less sack cleaner, smaller power, therefore, has saved the energy;

2. improve the work-ing life of equipment:

Of the present utility model rational in infrastructure, use less sack cleaner, induced draft fan, just make equipment wind-force of the present utility model less, just reduced the cycle index of aluminum oxide, reduced the wearing and tearing of equipment, promptly improved the work-ing life of equipment;

3. simple in structure:

The utility model removes the existing smoke evacuation house steward that disappeared and goes up the absorption reaction storehouse that is provided with, but the house steward that will discharge fume is continuous with hopper, utilizes the fresh aluminum oxide absorption flue gas in the hopper, makes it simple in structure.

Embodiment:

The utility model comprises hopper 5, the electrolyzer 3 with feed opening 4, be provided with gas skirt 8 corresponding to the top of pinkeye 6, the bottom of hopper 5, gas skirt 8 links to each other with reactor 10 by flue 9, hopper 5 links to each other with sack cleaner 14 by smoke evacuation arm 12, smoke evacuation house steward 13, sack cleaner 14 links to each other with chimney 17 by airduct 15, induced draft fan 16, and the bottom of sack cleaner 14 links to each other with aluminum oxide warehouse 2 by returning charge chute 11, material elevator 1.

Reactor 10 comprises housing 18, and housing 18 tops are fluidisation plate 19, and the top in the fluidisation hole 20 on the fluidisation plate 19 is a shelves material cover 21, is support plate 22 between shelves material cover 21 and the fluidisation plate 19.

Below in conjunction with a description of drawings course of action of the present utility model:

The flue gas that produces in the electrolysis production process in the electrolyzer 3, discharge, enter gas skirt 8, flue 9 to reactor 10 by pinkeye 6, flue gas carries out absorption reaction (aluminum oxide after the absorption is directly in feed opening 4 enters electrolyzer 3) by the reactor 10 in the hopper 5; Again through hopper 5, smoke evacuation arm 12 converge flue gas up to standard to the house steward 13 that discharges fume, the sack cleaner 14, enter atmosphere through airduct 15, induced draft fan 16, chimney 17; Sack cleaner 14 is collected a spot of aluminum fluoride, to hopper 5, carries out electrolysis production through returning charge chute 11, material elevator 1, aluminum oxide warehouse 2, Conveying Chute 7.
