In, it is one of current main method using laggard pyrolysis furnace cracking is disassembled, the method is simple and practical, can fully reclaim old and useless battery
In valuable material, but organic exhaust gas concentration height, complicated component caused by pyrolysis furnace in cracking process, the smell is awful, to rear end
Emission control technology requires higher.
At present similarity waste gas frequently with method mainly have：Condensation method, catalytic oxidation, absorption process, micro- electric charge point
Solution etc..
Condensation method principle is relatively simple, is removing and reclaims the better method of organic exhaust gas, but having for very high concentrations
Machine waste gas, the higher rate of recovery is obtained, not only horsepower requirements are high, and the organic liquid waste reclaimed is hazardous waste, handling
It is complicated with high program.Absorption process has certain effect to the organic exhaust gas for handling high concentration, but the organic exhaust gas of complicated component is deposited
Absorb not thoroughly, equipment requirement is high, the smell is awful and is relatively also easy to produce the consequence of secondary pollution.Catalysis oxidation and micro- electric charge decompose
Method has a preferable treatment effect for the organic exhaust gas of low concentration, but for high concentration organic exhaust gas exist processing not thoroughly,
The smell is awful and is also easy to produce the risk of secondary pollution.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of processing of waste and old electrokinetic cell cracking waste gas
Method, it can stablize, efficiently handle waste and old electrokinetic cell cracking waste gas, and non-secondary pollution, be adapted to processing high concentration, small
The fluorine-containing organic exhaust gas of tolerance, complicated component.
A kind of processing method of waste and old electrokinetic cell cracking waste gas proposed by the present invention, comprises the following steps：
S1, by waste and old electrokinetic cell cracking waste gas be passed through in direct combustion furnace, air atmosphere burns to obtain a waste gas；
S2, a waste gas is passed through in flash cold column, spray chilling obtains secondary waste gas；
S3, by secondary waste gas spray washing, then carry out alkali lye and spray to obtain emission.
The present invention is using the waste and old electrokinetic cell cracking of direct combustion furnace+flash cold column+multi-stage spray system in combination PROCESS FOR TREATMENT
Waste gas, waste and old electrokinetic cell cracking waste gas after heat exchange by entering in direct combustion furnace, and direct combustion furnace is by supplementing air
Make waste gas abundant combustion decomposition in stove, organic waste-gas purification efficiency can reach 99%；Waste gas is carried out by flash cold column again
Chilling, the temperature range that quenching process is easily formed across bioxin, avoid the formation of bioxin；Finally pass through multi-stage spray system
System further removes the pollution factors such as fluoride, and emission meets after processing《GB16297-1996 atmosphere pollution comprehensive discharges
Standard》In regulation.
Preferably, waste and old electrokinetic cell cracking waste gas includes：Ethylene carbonate, ethyl chloride, 1,3- propane sultones,
