Due to the application of the sealing block disclosed by the utility model, the leakproofness of a gas gathering system can be improved; and on the premise of ensuring the high gas gathering efficiency, the single-tank smoke exhaust rate can be reduced by over 20 percent and the operating power consumption of a smoke purification system can be reduced by over 40kwh/t-Al.
Description
Technical field
The utility model relates to aluminium cell, especially designs a kind of sealing block that is used to improve the aluminium cell sealing property.
Background technology
Modern electrolytic aluminum industrial production adopts sodium aluminum fluoride-aluminum oxide molten salt electrolysis.Under 950 ℃-970 ℃, carry out electrochemical reaction on the two poles of the earth in the electrolyzer, cathode product is a product aluminium liquid; Regularly in electrolyzer, extract out; Anodic product mainly is carbonic acid gas and CO gas, flue gas staple CO2, CO, HF, CF4 and fluorine-containing dust that electrolyzer gives out, and fluorochemical can cause air environmental pollution; Directly the infringement human health must be carried out harmless treatment, recycling.Qualified discharge after the valuables such as current electrolysis groove flue gas passes through natural gas gathering system and smoke exhaust pipe introducing flue gas purification system purifies, recovery fluorochemical, dust.
The airtight natural gas gathering system of outstanding aluminium cell can realize high gas collecting efficiency; Avoid excessive fluorine-containing flue gas to distribute and outside groove, worsen the shopwork environment; The raising of gas collecting efficiency can reduce electrolyzer list groove exhaust smoke level accordingly; Thereby reduce the running cost of purification system and the heat dissipation capacity of electrolyzer, reach the energy-saving and emission-reduction purpose.Electrolysis flue gas smoke evacuation-purification system operation the power consumption of modern aluminum electrolysis enterprise is about 250kw.h/t-Al, accounts for 1/3rd of electrolytic aluminium factory power power consumption; The heat energy of getting rid of through flue gas accounts for electrolyzer heat radiation energy consumption more than 30%, and therefore, the airtight performance of electrolyzer natural gas gathering system concerns the gas collecting efficiency of electrolyzer, smoking gas containing fluorine comprehensive purifying efficient, gas collection purification system running cost and electrolyzer energy-saving effect.
Electrolyzer smoke evacuation natural gas gathering system by the fixed level set gas hood plate of pot superstructure, door type column and all around movably the duraluminum cover plate constitute.The smoking gas containing fluorine that produces in the electrolyzer is closed in above airtight " air collecting chamber " and introduces flue gas purification system through the electrolyzer flue gas smoke exhaust pipe that links to each other with air collecting chamber and purifies.The horizontal cover plate both sides of aluminum current electrolyzer natural gas gathering system all have " square opening ", and the anode block aluminium guide bar just in time is installed in the corresponding square opening on the electrolyzer.For guarantee to change in the aluminum electrolysis anode block easy for installation with guarantee being electrically insulated of anode aluminium guide bar and pot superstructure; Need to keep the gap about 8mm between " square opening " and the aluminium guide bar, the anode groups number of installing on the quantity of square opening and the electrolyzer is consistent.As 40 groups of anodes are arranged on the 320kA electrolyzer, then horizontal cover plate both sides just have corresponding 40 " square openings ", and the total area in gap is 0.12～0.15 m between itself and the anode rod
2This area accounts for whole electrolyzer natural gas gathering system about 40% of the area that always leaks gas; Current do not have the ideal sealing means to this slit, and the existence in this type gas leakage slit reduces the gas collection effect of electrolyzer, for guaranteeing the ideal gas collecting efficiency; Single groove exhaust smoke level be certainly will improve, purification fume exhaust system running cost and electrolyzer energy consumption increased.
The utility model content
The purpose of the utility model is exactly the problem that exists to prior art, and a kind of sealing block that is used to improve the aluminium cell sealing property is provided.
Above-mentioned purpose realizes through following proposal:
A kind of sealing block that is used to improve the electrolyzer sealing property, it comprises an insulation L-square, it is characterized in that, on said L-square, is inlaid with ferromegnetism and inserts.
Sealing block according to above-mentioned is characterized in that, said L-square is the polymer insulcrete.
Sealing block according to above-mentioned is characterized in that, it is 2 that said ferromegnetism is inserted, and is embedded in respectively on two vertical edges of L-square.
The beneficial effect of the utility model: the sealing block that uses the utility model; Can improve the stopping property of natural gas gathering system; Under the prerequisite that guarantees high gas collecting efficiency, can reduce single groove exhaust smoke level more than 20%, flue gas purification system operation power consumption can reduce more than the 40kwh/t-Al.
Description of drawings
Fig. 1 is the structural representation of the sealing block of the utility model;
Fig. 2 is the left side view of Fig. 1;
Fig. 3 is to use the synoptic diagram of the gas collecting skirt of the utility model sealing block.
Embodiment
Referring to Fig. 1 and Fig. 2, the sealing block that being used to of the utility model improved the electrolyzer sealing property comprises an insulation L-square 1, on L-square 1, is inlaid with ferromegnetism and inserts 2.In the present embodiment, it 2 is 2 that ferromegnetism is inserted, and is embedded in respectively on two vertical edges of L-square 1.Ferromegnetism can be set as required insert 2 number for inlaying the position.L-square 1 can be selected the polymer insulcrete for use.
The method of use of sealing block is referring to Fig. 3.Gas skirt comprises duraluminum cover plate 6 and horizontal cover plate 3, on cover plate 3, has " square opening ", has slit 4 between square opening and the anode rod 5.Left part referring to Fig. 3; The gap area that forms at each " square opening " and aluminium guide bar relatively be provided with two movably, sealing block that be electrically insulated, that have the magnetic attraction fixed function; When changing anode, the anode rod 5 of anode block can directly move apart is close to the sealing block of installing around it, renew anode after; Suitably move adjustment sealing block position; Make the sealing block inboard be close to the aluminium guide bar sidepiece, magnetic attraction between inserting through the ferromegnetism on horizontal cover plate and the sealing block guarantee the sealing block bottom be close to " square opening " on every side horizontal cover plate upper surface and make it fixing, the slit between so original square opening and the anode rod is just sealed by sealing block effectively; Thereby the raising gas collecting efficiency reduces single groove exhaust smoke level.
