Description
Technical field
The utility model belongs to aluminum electrolysis flue gas purification equipment technical field.
Background technology
Cryolite-alumina Melt electrolysis aluminium metallurgy production process in, can be produced in electrolytic cell a large amount of pernicious gases and
Dust, to mitigate pollution of such harmful substance to surrounding environment and animals and plants, and fluoride is reclaimed, it is necessary to take purification to arrange
Apply, turn harm into good.Existing purification method has two kinds of dry and wet, and wet method is low due to purification efficiency, serious to equipment corrosion,
And easily cause secondary pollution, it is basic at present without.Dry cleaning is to the direct recycling of fluoride, process is simple, purification
Efficiency high, does not result in two pollutions, technology maturation reliability.The specific method of dry cleaning is that electrolytic cell is excluded into pernicious gas to converge
Total to enter the total smoke pipe of cleaning system, the aluminum oxide come with chute conveying enters reactor in the lump, flue gas is fully mixed with aluminum oxide
Reaction, hydrogen fluoride gas in absorption flue gas are closed, reaction equation is：AI2O3+6HF→2AIF3+3H2O, the load after adsorption reaction
Fluorine alumina and flue gas carry out gas solid separation by deduster, and purified gas is emptied through chimney, and material returns to electrolytic cell life
Product is used.The key equipment of dry cleaning is the nozzle in reactor and the inside, and nozzle quality directly affects purification efficiency.
The reactor that current large pre-baked cell cleaning system is used has VRI devices, Venturi and pipe reaction
Device, but appearance reaction adsorption effect is not good and wooden partition is easily damaged in various degree in actual applications, and nozzle wear is damaged
Bad and air feed pipe break-through.Reactor and nozzle in prior art as shown in Figure 1, material enter reactor b from chute a, anti-
Answer in device, nozzle d upper ends are connected with chute a discharging openings by flange and bolt f, nozzle bottom is equipped with squirrel-cage nozzle base sheet e,
Blower fan is blown into wind from airduct c, and the alumina material that will be fallen on nozzle base sheet e is dispelled.Accumulate over a long period feed intake during, spray
The mouth d and its connecting bolt f with tremie pipe, the bottom parts of nozzle base sheet e and vertical lacing wire part are oxidized aluminium and seriously grind
Damage up to rubbing, bottom parts are all punched through by material, the wooden partition of reactor is washed away by irregular aluminum oxide and is also subjected to abrasion,
Need to repair replacing repeatedly, increased cost of equipment maintenance and have a strong impact on purification efficiency, cause environmental monitoring control parameter ripple
It is dynamic and exceeded.
The content of the invention
The purpose of this utility model is precisely in order to solve the problems, such as above-mentioned prior art, there is provided one kind can realize without
Blower fan air feed, simple structure, it is conveniently replaceable and the smaller, blanking of being worn and torn to wooden partition is steady, advantages of good adsorption effect electrolytic aluminum smoke is net
Change reactor nozzle, to reduce cost of equipment maintenance and ensure purification efficiency.
The purpose of this utility model is achieved through the following technical solutions：
Electrolytic aluminum smoke purification reactor, including reactor shell, material chute and chute from upstream introducing housing
The nozzle of discharging opening connection；The nozzle includes the flanged (FLGD) cylinder blanking tube in top and is welded in the mountain of cylinder blanking tube bottom
Shape deflector；The chevron deflector is welded together by two pieces of top margins and rectangular slab that base is opened is welded, two pieces of squares
Shape plate is welded into isosceles triangular structure with the wearing plate of bottom surface；The top for chevron deflector is offered in the middle of blanking tube bottom
The angle of point insertion, along both contact point welding between blanking tube bottom and deflector, blanking tube bottom and deflector it
Between self-assembling formation discharging gap.
The utility model without blower fan air feed, its simple structure, be conveniently replaceable and to wooden partition wear and tear smaller, service life
It is long.Blanking is steady and advantages of good adsorption effect.Can simultaneously realize that different groove profile specification cleaning system reactor nozzle devices are used, can save
Save site space, energy saving and reduce aluminum oxide breakage, transformation maintenance cost is low.Purification efficiency is up to 99%, it can be ensured that environment
Monitoring parameter qualified discharge.

Specific embodiment
Below by embodiment, the utility model is described in further detail.
Aluminum electrolytic decontamination system response device as shown in Figure 2, including reactor shell 1, the thing from upstream introducing housing
Material chute 2 and the nozzle of chute discharging opening connection.The nozzle includes the cylinder blanking tube 3 at top flanged 4 and is welded in circle
The chevron deflector 5 of the bottom of post blanking tube 3, chevron deflector 5 is welded together and rectangular slab that base is opened by two pieces of top margins
It is welded, two pieces of rectangular slabs are welded into isosceles triangular structure with the wearing plate 6 of bottom surface.Blanking tube 3 is offered in the middle of bottom
For the angle of the top insertion of chevron deflector 5, welded along angle between the bottom of blanking tube 3 and deflector 5, therebetween certainly
So form discharging gap 7, it can be ensured that blanking is unimpeded.Can also be using other welderings between the bottom of blanking tube 3 and deflector 5
Binding structure, as long as leaving the gap that can ensure that blanking is unobstructed.The utility model is without using blower fan air feed and increases injection
Device, simple structure is easy for installation, and height, big I are amplified according to field apparatus different proportion, effectively simplify live all kinds of confessions
Wind pipeline and valve, it is not necessary to adjust, this device can synchronously be used after making with regard to original reactor nozzle flange, it is not necessary to be made
More transformations, pull down the air feed duct occlusion of former reactor.Aluminum oxide is sent to spray by the utility model using upstream tray 2
Mouth, freely falls to the cylindrical blanking tube 3 of nozzle, then falls into deflector 5, and the chevron slope top along deflector freely falls input
Gas cleaning is participated in reactor, aluminum oxide is carried out abundant adsorption reaction with pernicious gas by negative pressure, appointed in nothing
What auxiliary power situation feeds intake, effectively reduce aluminum oxide abrasion and the abrasion of material diffusion couple wooden partition, it is to avoid material flies upward
And waste, and purification efficiency is low and the uncontrolled problem of environmental control parameters, while production run maintenance cost is substantially reduced.
