Abstract
The utility model discloses a smoke collecting hood of an aluminium electrolysis cell. The smoke collecting hood of the aluminium electrolysis cell comprises an electrolysis cell, and a smoke collecting hood positioned inside the electrolysis cell and covering the electrolysis cell, wherein a smoke exhausting passage is arranged on the smoke collecting hood; the smoke exhausting passage is connected with a smoke exhausting pipe; exhaust holes are formed in the smoke exhausting passage; the diameter of the exhaust hole near the smoke exhausting pipe is smaller than that far from the smoke exhausting pipe; multiple condensing tubes are arranged inside the smoke exhausting passage; a waste liquid tank is arranged inside an exhaust passage below each condensing tube. The smoke collecting hood of the aluminium electrolysis cell is simple in structure; in the length direction of the electrolysis cell, the exhaust holes with different diameters are formed according to the different distances from the exhaust holes to the smoke exhausting pipe, and the diameters of the exhaust holes increase along with increase of the distance, so that exhaust amount at a flue end and exhaust amount at an aluminum discharging end are balanced to achieve balanced exhaust amount at the two ends; therefore, the smoke collecting hood of an aluminium electrolysis cell is good in exhausting effect and reasonable in structure.
Description
Technical field
The utility model belongs to aluminium electrolytic equipment field, is specifically related to a kind of fume collecting hood of aluminum cell.
Background technology
At present, in Aluminium Electrolysis, for being delivered to purification system, processes the obnoxious flavour of generation, in electrolyzer, be all provided with groove cover plate, and have venting hole on groove cover plate, by venting hole, by obnoxious flavour suction smoke discharging pipe, through smoke exhaust pipe, deliver to flue gas purification system.During general venting hole, on electrolyzer inside groove cover plate length direction, open equidistant, the equirotal hole of a row, because aluminium cell inside groove cover plate length is longer, flue end negative pressure from smoke exhaust pipe close to is larger, and may there is malleation away from the aluminium inlet of smoke exhaust pipe, therefore free air delivery is inhomogeneous, causes smoke discharging pipe can not arrange obnoxious flavour, the obnoxious flavour electrolyzer of will amorphously emerging, the gas collecting efficiency that affects electrolyzer, pollutes surrounding environment.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of fume collecting hood of aluminum cell is provided, its simple in structure, good exhaust effect.
The technical scheme that the utility model adopts is: a kind of fume collecting hood of aluminum cell, comprise electrolyzer, be positioned at electrolyzer and cover smoke collection cover thereon, described smoke collection cover is provided with discharge flue, and discharge flue is connected with smoke exhaust pipe, and described discharge flue is provided with venting hole, described venting hole from smoke exhaust pipe more close to, its diameter is less, is provided with several prolongs in described discharge flue, and the inside of the exhaust-duct, below of each prolong is equipped with waste liquid tank.
As preferably, described prolong is connected on the inwall of discharge flue.
The beneficial effects of the utility model are: the utility model is simple in structure, because it is on electrolyzer length direction, different according to the distance of venting hole position and smoke pipe, adopt the venting hole of different diameter, and distance is larger, the diameter of venting hole is also larger, like this with regard to balance the free air delivery size of flue end and aluminium inlet, the free air delivery that reaches two ends is balanced, thereby make its good exhaust effect, rational in infrastructure, be provided with prolong, can carry out preliminary purification to obnoxious flavour, connect liquid bath, be convenient to collect condensed waste liquid, reduced the pollution that surrounding environment is caused.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model A-A sectional view.
In figure: 1, electrolyzer; 2, smoke collection cover; 3, discharge flue; 4, smoke exhaust pipe; 5, venting hole; 6, prolong; 7, connect liquid bath.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
Embodiment: as depicted in figs. 1 and 2, the utility model comprises electrolyzer 1, be positioned at electrolyzer 1 and cover smoke collection cover 2 thereon, described smoke collection cover 2 is provided with discharge flue 3, and discharge flue 3 is connected with smoke exhaust pipe 4, described discharge flue 3 is provided with venting hole 5, described venting hole 5 from smoke exhaust pipe 4 more close to, its diameter is less, in described discharge flue 3, be provided with several prolongs 6, this prolong 6 is connected on the inwall of discharge flue 3, and the inside of the exhaust-duct, below of each prolong 6 is equipped with waste liquid tank.
The utility model is simple in structure, because it is on electrolyzer 1 length direction, different according to the distance of venting hole 5 positions and smoke pipe, adopt the venting hole 5 of different diameter, and distance is larger, the diameter of venting hole 5 is also larger, like this with regard to balance the free air delivery size of flue end and aluminium inlet, the free air delivery that reaches two ends is balanced, thereby make its good exhaust effect, rational in infrastructure, be provided with prolong 6, can carry out preliminary purification to obnoxious flavour, connect liquid bath 7, be convenient to collect condensed waste liquid, reduced the pollution that surrounding environment is caused.
Claims (2)
1. a fume collecting hood of aluminum cell, comprise electrolyzer, be positioned at electrolyzer and cover smoke collection cover thereon, described smoke collection cover is provided with discharge flue, and discharge flue is connected with smoke exhaust pipe, it is characterized in that: described discharge flue is provided with venting hole, described venting hole from smoke exhaust pipe more close to, its diameter is less, is provided with several prolongs in described discharge flue, and the inside of the exhaust-duct, below of each prolong is equipped with waste liquid tank.
2. fume collecting hood of aluminum cell according to claim 1, is characterized in that: described prolong is connected on the inwall of discharge flue.
