Abstract
The utility model discloses a configuration structure of a residual electrode cooling device of an aluminum electrolytic workshop, which comprises aluminum electrolytic baths (1), and residual electrode cooling devices (2) with fume collecting devices are arranged on a large surface in the aluminum electrolytic workshop at intervals of two to three aluminum electrolytic baths (1). As the technical scheme is adopted, the configuration structure enables all smoke dust, hot gas and fluorides diffused by a residual electrode to enter an electrolytic fume purifying system, not only reaches the requirement for environmental protection commendably, but also greatly improves the working environment of the aluminum electrolytic workshop. The used residual electrode cooling devices also have the advantages of simple structure and convenience for movement. Roller wheels are arranged on the residual electrode cooling devices so that the residual electrode cooling devices are convenient to move and the electrode replacement and the residual electrode cooling work are also convenient.
Description
Technical field
The utility model relates to the configuration structure of aluminium electrolysis shop anode scrap refrigerating unit, belongs to the aluminum electrolysis technology field.
Background technology
Along with the continuous progress of modern pre-baked cell technologies, the strength of current of aluminium cell constantly increases, to obtain increasing single series production capacity.Simultaneously, because country is more and more higher to the environmental requirement of aluminium electrolysis enterprise, the quantity discharged of flue dust and fluorochemical requires fewer and feweri, makes aluminium electrolysis enterprise have only and constantly carries out technical renovation to reach the environmental requirement of country.
At present, electrolysis enterprise has done finely for the sealing of potroom electrolyzer, gas collecting efficiency can reach more than 99%, but being the anode scrap that will swap out, traditional anode scrap refrigerative mode directly hangs naturally cooling in the anode tray on the big face in electrolyzer, the flue dust and the not process processing of fluorochemical that can cause anode scrap to distribute directly are discharged in the atmosphere, cause the pollution to environment, do not reach national team's environmental protection requirement, and the potroom work under bad environment.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of and reduce anode scrap when cooling flue gas and fluorochemical is discharged into atmosphere, reduce environmental pollution, improve the configuration structure of the aluminium electrolysis shop anode scrap refrigerating unit of shopwork environment, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: it comprises aluminium cell, and on the big face in aluminium electrolysis shop, every interval 2-3 aluminium cell is provided with the anode scrap refrigerating unit of a band smoke gas collecting apparatus.
The anode scrap refrigerating unit is the system of a sealing, and it is removable cover that a face is arranged in the sealing system, is connected with dust collecting system on the anode scrap refrigerating unit, and dust collecting system is connected with factory building smoke pipe outward.
On the anode scrap refrigerating unit, roller is installed.
Compared with the prior art, the utility model is owing to adopted technique scheme, all flue dust, hot gas, the fluorochemical that make anode scrap distribute all enter the electrolysis flue gas purification system, not only well reach environmental protection requirement, and improve the Working environment of potroom greatly.Employed anode scrap refrigerating unit also has simple in structure, the convenient advantage that moves.On the anode scrap device, roller is installed, is so promptly made things convenient for the anode scrap refrigerating unit to move, also make things convenient for change poles and anode scrap cooling operations.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Embodiment: at the big face of potroom 4, place an anode scrap refrigerating unit 2 of being with smoke gas collecting apparatus every 2 aluminium cells 1 or 3 aluminium cells 1, anode scrap refrigerating unit 2 is systems of a sealing, having only a face is removable cover, and be connected with dust collecting system 3 and be connected with smoke pipe outside aluminium electrolysis shop 4 factory buildings on the anode scrap refrigerating unit, total system is in subnormal ambient always.When changing anode, earlier the removable cover of anode scrap refrigerating unit 2 is opened, will be in anode scrap refrigerating unit 2 from the anode scrap handling that swaps out in the electrolyzer, cover cover plate then, make the anode scrap refrigerating unit be in air-tight state, the flue dust that anode scrap comes out, hot gas, fluorochemical all enter in the outer smoke pipe of factory building by dust collecting system 3, enter into the electrolysis flue gas purification system by smoke pipe again.
Be 337kt/a now with aluminium electrolysis shop 4 designed capacitys, 288 420KA electrolyzers have been installed altogether have been example, potroom is divided into 8 districts, anode scrap refrigerating unit 2 of per 3 aluminium cells, 1 configuration in 1,2,7,8 districts, totally 48 overlap anode scrap refrigerating units 2, and this 48 cover anode scrap refrigerating unit is connected by the smoke pipe outside dust collecting system 3 and the factory building.Because anode scrap refrigerating unit 2 is band rollers, when 1, after 8 district's anode scraps have cooled off, by trailer anode scrap refrigerating unit 2 and anode scrap are transported to anode composing room, composing room takes out anode scrap at anode, new anode is loaded onto,, carried out once more change poles and anode scrap cooling operations again by trailer transportation to 3,6 districts.
Claims (3)
