Description
Technical field
The utility model belongs to aluminium electroloysis waste lining pretreatment system technical field.
Background technique
Waste lining is, due to the infiltration of high-temperature electrolysis confrontation Pot Lining, corrosion, to cause aluminium electric during aluminum electrolysis
Solution Pot Lining structure is deformed, rupture, high temperature molten aluminum and electrolyte from the crack infiltration Pot Lining of these deformations and rupture,
So as to cause electrolytic cell can not produce normally and stop generating when slot is repaired.Since slot liner material is sent out with electrolyte at high temperature for a long time
Raw electrochemical reaction, has adsorbed a large amount of fluoride and a certain amount of harmful substance, while also generating some noxious materials, has become
Its factor to cause damages when storing up to environment.How waste lining is subjected to harmless treatment, becomes the weight of waste lining processing
Point and difficult point.
The method for handling waste lining is more, is divided into wet-treating and pyrogenic attack two major classes substantially, in wet-treating process
In, when putting into water and other solvents progress leaching process after waste lining is crushed, waste lining meets the water meeting a large amount of ammonias of output, right
Environment and operator cause larger harm, it is necessary to be resolved.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, provides one kind in wet-treating aluminium electroloysis waste lining mistake
Cheng Zhong can effectively prevent ammonia leakage, to avoid the pre- leaching system of aluminium electroloysis waste lining endangered environment and operator.
The purpose of this utility model is achieved through the following technical solutions:
A kind of pre- leaching system of aluminium electroloysis waste lining, including installing the closed pre- leaching tanks being erected in workshop, being connected to
The feeding chute of closed pre- leaching tanks discharge port is set to being opened by electric drive hydraulic thruster control for closed pre- leaching tanks discharge port
Discharge door, be installed on above pre- leaching tanks belt conveyor, be set to above belt conveyor feeding electric hoist, from close
Pre- leaching groove top portion is closed to draw and the tail gas absorption pipe passed to below closed pre- leaching tanks, the tail gas being connected on tail gas absorption pipe
Blower and connect the offgas duct of exhaust fan, the one-stage water wash for the sequential communication being set to outside workshop washs tower, second level water wash column,
Level-one sulfuric acid scrubbing tower, second level sulfuric acid scrubbing tower, the rear end of the offgas duct is connected to the air inlet that one-stage water wash washs tower, described
The slot bottom of closed pre- leaching tanks is the surface groove bottom tilted down towards discharge port direction.
2 or more closed pre- leaching tanks are arranged side by side in the utility model in workshop.
Using the utility model, the broken waste lining installed can be transported to pre- leaching system factory with box feed bin
Room is allocated and transported box feed bin to workshop overhead from ground using feeding electric hoist, by the waste lining discharging in box feed bin to skin
Waste lining is delivered to closed pre- leaching tanks automatically and is leached in advance by band conveyer, belt conveyor.Presoak out the tail gas generated
(predominantly ammonia), which using exhaust fan is evacuated to one-stage water wash by offgas duct and washs tower and carry out one-stage water wash, to be washed, washes again through second level
Reach discharge standard emptying after washing tower, level-one sulfuric acid scrubbing tower and the washing of second level sulfuric acid scrubbing tower.After pre- leaching process
Waste lining slurry is automatically controlled using electric drive hydraulic thruster and opens discharge door, enters subsequent leaching pond by feeding chute.
The utility model can effectively prevent letting out for a large amount of Tail Gas generated during wet-treating aluminium electroloysis waste lining
Leakage, avoids the harm to environment and operator.Tail Gas is sent under conditions of being completely closed carries out two-stage water washing
With two-stage sulfuric acid scrubbing, discharge standard emptying can be fully achieved, realize the zero-emission of Tail Gas.The conveying of waste lining and add
Material and the discharging for passing through the waste lining leached in advance, which are all realized, to be automatically performed, and is not required to very important person and is directly operated, time saving and energy saving, peace
Loopful is protected.The utility model is compact-sized, and whole system is spatially arranged, and area occupied is small.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A-A schematic cross-sectional view of Fig. 1.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of pre- leaching system of aluminium electroloysis waste lining is erected at closed in workshop 1 including installation
Pre- leaching tanks 5, the feeding chute 7 for being connected to closed pre- leaching tanks discharge port, be set to closed pre- leaching tanks discharge port by electricity
The discharge door 15 of the control unlatching of hydrodynamic pressure push rod 6, is set to Belt Conveying at the belt conveyor 3 being installed on above pre- leaching tanks
Feeding electric hoist 2 above machine draws from closed pre- leaching groove top portion and passes to the tail gas absorption pipe below closed pre- leaching tanks
