Abstract
The utility model discloses a dust catcher. The dust catcher is provided inside with a lower box, a middle box and an upper box. The middle box is provided with a filter bag; the lower box is provided with a dust bucket; an n-shaped arc smoke tube is connected with the lower box; the smoke inlet of the arc smoke tube is downward. The utility model separates oxide aluminum with fluorine from most smoke through the n-shaped arc smoke tube; the separated oxide aluminum enters the dust bucket of the dust catcher to relieve the duty of filter bag and prolong the working life of the filter bag. Meanwhile, the utility model adopts an air lifting machine to spray uniformly the fresh oxide aluminum into the smoke gas in dust catcher so as to mix sufficiently oxide aluminum with smoke gas, thereby improving the hydrogen-fluoride absorption efficiency and achieving the purpose of environmental protection. Moreover, the utility model improves the recovery and utilization rate of HF raw materials and reduces the consumption of raw materials.
Description
Technical field:
The utility model relates to a kind of fly-ash separator that is used for the electrolytic aluminum smoke purification system, belongs to the fly-ash separator technical field.
Background technology:
In the electrolytic aluminum industrial production, electrolyzer will produce a large amount of flue gases that contains HF in aluminium electrolysis process, if HF enters into surrounding environment, will produce environmental pollution, and the animals and plants body is produced toxic side effect.In the prior art, adopt the flue gas dry cleaning measure usually, promptly adopt hydrogen fluoride in the alumina adsorption flue gas with the nuisance in the flue, control fluorochemical quantity discharged to reach state environmental emissioning standard, reduces the pollution to surrounding environment.
At present in China's aluminium electrolytic flue dry cleaning technology, general using Aluminium Electrolysis raw alumina has the mechanism of stronger adsorptive power to hydrogen fluoride gas, with it smoking gas containing fluorine is carried out dry cleaning, the nuisance gases such as hydrogen fluoride in the absorption flue gas.The fly-ash separator of its use normally feeds the flue gas that is pre-mixed fluoro-containing alumina from the flue of fly-ash separator, by aluminum oxide the objectionable impurities in the flue gas is adsorbed, aluminum oxide behind the absorption flue gas is filtered by the filter bag of fly-ash separator, by delivering in the fluoro-containing alumina storehouse directly emptying of the flue gas that is cleaned after the ash bucket collection.Because the fluoro-containing alumina that is pre-mixed in the flue gas is without pre-separation, cause the filter bag workload of fly-ash separator big, the deashing number of times increases, make the easier breakage of filter bag, and there is a relatively low problem of the percentage composition of fresh aluminum oxide in the fly-ash separator, influence hydrogen fluoride gas adsorption cleaning efficient, used decontamination effect improving not ideal enough.
Summary of the invention:
The purpose of this utility model is: provide a kind of working life of filter bag, fly-ash separator of raising purification efficiency of prolonging, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises fly-ash separator housing (1), in housing (1), be provided with lower box (2), middle casing (3) and upper box (10), in on middle casing (3), establishing filter bag (8) is arranged, have ash bucket (4) at lower box (2), it is characterized in that: on lower box (2), be connected with the arc flue (5) of n type, arc flue (5) to advance mouth (6) downward; Be provided with the into air hoist (7) of fly-ash separator lower box (2) that directly to feed in raw material in the below of lower box (2).
The utility model utilizes the arc flue of n type; isolate the fluoro-containing alumina in most of flue gas; the fluoro-containing alumina that separates enters in the ash bucket of fly-ash separator; alleviated the burden of filter bag; prolonged the working life of filter bag; adopt air hoist that fresh aluminum oxide evenly is ejected in the interior flue gas of fly-ash separator simultaneously; can make aluminum oxide and flue gas thorough mixing; improved the degree of fresh aluminum oxide in the flue gas; thereby improved hydrogen fluoride gas adsorption cleaning efficient; reach the purpose of protection environment, also improved raw-material recovery utilization rates such as HF simultaneously, reduce raw-material consumption.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the right view of accompanying drawing 1.
Embodiment:
Embodiment of the present utility model: fly-ash separator housing of the present utility model (1) can adopt existing finished product, and adopts a plurality of unit fly-ash separator to work simultaneously in flue gas purification system, produces needs to satisfy.In housing (1), produce lower box (2), middle casing (3) and upper box (10), on middle casing (3) card, filter bag (8) is installed, at lower box (2) ash bucket (4) is installed down, go up the arc flue (5) that connects one section n type at lower box (2), the mouth (6) that advances of arc flue (5) is installed downwards, arc flue is arranged in the middle casing, connect an air hoist (7) in the below of lower box (2) at last and get final product, the outlet pipe that sky is carried directly is connected in the fly-ash separator lower box (2).The flue gas that is pre-mixed fluoro-containing alumina enters arc flue (5) from advancing mouth (6), centrifugation goes out the fluoro-containing alumina in most of flue gas in arc flue (5), the aluminum oxide that separates enters in the ash bucket (4), simultaneously, flue gas enters into lower box (2), fresh aluminum oxide is driven into lower box (2) with small-sized air hoist (7), evenly be ejected in the flue gas in the lower box (2), behind the flue gas thorough mixing, a small amount of oarse-grained aluminum oxide drops in the ash bucket (4), most aluminum oxide moves in the middle casing (3) of fly-ash separator with flue gas, filtered by filter bag (8) at last, on filter bag (8), pulse compression air deashing in reverse-blow pipe (9) drops in the ash bucket (4), fluoro-containing alumina in the ash bucket (4) is transported to the fluoro-containing alumina storehouse after collecting, and the flue gas after being cleaned enters smoke-uptake by upper box (10), at last by the chimney emptying.
Claims (2)
1. fly-ash separator, it comprises fly-ash separator housing (1), in housing (1), be provided with lower box (2), middle casing (3) and upper box (10), in on middle casing (3), establishing filter bag (8) is arranged, have ash bucket (4) at lower box (2), it is characterized in that: on lower box (2), be connected with the arc flue (5) of n type, arc flue (5) to advance mouth (6) downward.
