Abstract
The invention discloses a method for configurating cooling devices of residual anode carbon blocks of an aluminum electrolyser in an electrolysis shop. The cooling devices are arranged at a vestibule near the electrolysis shop and are arranged in parallel to the electrolyser; a dust-collecting pipeline for discharging flue gas is connected to an electrolytic flue gas purifying system so as to perform treatment. The two groups of cooling devices are adopted and are respectively arranged at two ends of the electrolyser. The method has the advantages that the residual anode cooling devices of anodes for electrolytic production are arranged in the electrolysis shop, so that the high-temperature residual anodes are cooled; HF (Hydrogen Fluoride) gas and dust which are discharged by the residual anodes are collected and treated. The method has the advantages of being simple to operate and convenient to implement; the environmental friendliness is effectively realized and the body health of a worker is protected.
Description
Technical field
The present invention relates to metallurgical chemistry field, is that a kind of refrigerating unit of aluminium cell anode scrap charcoal piece is in the method for potroom configuration, the field that is mainly used in the cooling of aluminum electrolysis industry Anodic anode scrap and the flue gas of its discharge is carried out to collection and purification specifically.
Background technology
In aluminum electrolysis industry, utilize fused salt smelting method to produce metallic aluminium, need continuous consumable anode charcoal piece, and the anode scrap changing is all covered with ionogen, under high temperature action, can produce dust and HF gas.This is larger to health of human body and atmospheric environment harm, should give and processes and purify.
Conventionally, for the anode scrap of changing in electrolytic process, general requirement is placed on potroom, in refrigerating unit between anode scrap cooling station or novel residual anode processing, carry out cooling draught, but the configuration of these refrigerating units, often there is irrational place, for example refrigerating unit is placed on large of potroom, be not easy to out the safety that aluminium car travels and goes out aluminium operation, its position is because of too close edge, also being not easy to electrolysis multi-function crane is directly placed on anode scrap in refrigerating unit, often need secondary transhipment or handling, inefficiency but also cause anode scrap open-assembly time long not only, the toxic and harmful that it distributes, high temperature etc. are all the harm to environment and workers ' health.In addition refrigerating unit exhaust duct often to lay distance long, windage is larger, these are all unfavorable for environmental protection and energy-conservation.
In today of Considering Environmental more and more, electrolysis charcoal anode scrap is carried out to the cooling and purifying treatment flue gas that discharges in time efficiently, it is very necessary that environmental protection and routine safety are moved.
Summary of the invention
The present invention arranges a kind of refrigerating unit at potroom, through reasonably configuration and layout, thereby well anode scrap is carried out coolingly, reduces the discharge of anode scrap obnoxious flavour as far as possible, has protected environment and workers ' health.Concrete technical scheme is as follows:
The refrigerating unit of aluminium cell anode scrap charcoal piece, in a method for potroom configuration, is arranged on refrigerating unit near potroom vestibule place, and is arranged in juxtaposition with electrolyzer, the flue gas that discharges with dust collection pipe, be connected to Smoke Gas Purity by Electrolysis system and process.
Described refrigerating unit is 2 groups, is separately positioned on the two ends of electrolyzer.
Refrigerating unit is placed on and approaches potroom vestibule place, be arranged in juxtaposition with electrolyzer, one end is connected in Smoke Gas Purity by Electrolysis system with pipeline, utilize flue gas that negative pressure that Smoke Gas Purity by Electrolysis system produces produces anode scrap to siphon away can to carry out anode scrap simultaneously cooling, the flue gas after processing through smoke stack emission in atmosphere.This distributing style not only makes refrigerating unit next-door neighbour output zone, reduces transhipment distance, and can make full use of multifunction crane transporting anode scraps to refrigerating unit.At vestibule place, broad place is also beneficial to the operation of the transportation means such as fork truck, anode tray car, in time anode scrap is transported outward to processing.This collocation method has also greatly been saved the laid length of smoke discharging pipe in addition, not only saves executive cost, also because exhaust duct drag reduction makes working cost, reduces.
Advantage of the present invention is: by arrange the residual anode cooling device of anode for electrolysis production in potroom; to high temperature anode scrap, carry out cooling; and it is discharged to HF gas (hydrogen fluoride) and dust is collected and processed; have and make simple to operate, enforcement convenience, effectively protection of the environment, the healthy advantage of protection workman.
Accompanying drawing explanation
Fig. 1 is the configuration schematic diagram of residual anode cooling device in potroom;
In accompanying drawing: 1, refrigerating unit; 2, dust collection pipe; 3, electrolyzer; 4, Smoke Gas Purity by Electrolysis system.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further to explanation.
As shown in the figure, at potroom, near vestibule place, refrigerating unit 1 is set, and with workshop in electrolyzer 3 be arranged in juxtaposition, the flue gas of refrigerating unit 1 discharge is guided to and in Smoke Gas Purity by Electrolysis system 4, is carried out purifying treatment with dust collection pipe 2.
The present invention makes refrigerating unit next-door neighbour output zone, reduces transhipment distance, and can make full use of multifunction crane transporting anode scraps to refrigerating unit.
Refrigerating unit is near potroom vestibule place, and broad space is beneficial to the operation of the transportation means such as fork truck, anode tray car, in time anode scrap is transported outward to processing.
Collocation method of the present invention has greatly been saved the laid length of smoke discharging pipe, not only saves executive cost, also because exhaust duct drag reduction makes energy consumption cost, reduces.
