Abstract
The invention relates to a cooling system, in particular to an aluminum electrolysis anode scrap cooling system, which can be used for regularly collecting harmful gas hydrogen fluoride diffused by an anode scrap. In the aluminum electrolysis anode scrap cooling system, a cooling room is arranged between two electrolytic plants; one end of the cooling room is connected with a passage between the two electrolysis plants; a cooling area is formed in the cooling room; a gas collecting cover is arranged above each cooling area, and is connected with a horizontal flue; and the horizontal flue is connected with a collecting pipe. The system has the advantages: a flue is designed with different areas and flue gas is regularly collected into an electrolysis flue gas purifying system, so that the negative-pressure balance and flow distribution the flue gas are facilitated; and the cold-hot pressure difference of the flue gas is fully utilized, so that the flue gas flows smoothly towards an upper collecting flue, and is prevented from leaking outside. The skylight discharging indexes of the electrolysis plants can reach the international advanced level.
Description
Technical field
The present invention relates to a kind of cooling system, relate in particular to a kind of aluminum electrolytic residual electrode cooling system and the method for cooling that can the obnoxious flavour hydrogen fluoride that anode scrap distributes be carried out organized collection.
Background technology
Prebaked anode is adopted in existing electrolysis of aluminum, and the anode scrap that change poles gets off is placed on the anode tray of big end operating surface of potroom and cools off.There is following disadvantage in this method: anode scrap distributes obnoxious flavour hydrogen fluoride, and uncontrollable discharge is difficult to reach environmental protection standard at potroom; About 450 ℃ of the temperature of residue pole surface, great amount of heat is distributed in cooling, further worsens the potroom Working environment, if the deficiency in draught in the potroom also can have influence on the thermal equilibrium of electrolyzer; Anode scrap is placed on the anode tray, and floor space is bigger, influences the vehicle transport in the potroom.
Produce a large amount of harmful smokes in the anode scrap process of cooling, disperse is inner at potroom, and the severe exacerbation work situation influences health of human body, is difficult to reach environmental protection standard.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention provides a kind of aluminum electrolytic residual electrode cooling system and method for cooling, and purpose is that row's fluorine of potroom is reduced in a large number, collects the obnoxious flavour hydrogen fluoride that anode scrap distributes, thereby can satisfy the environmental requirement of increasingly stringent.
For reaching above-mentioned purpose, the present invention realizes through following technical proposals.
