Work field abraum salt yield is huge.During pesticide producing, the annual by-product abraum salt in the whole nation just reaches more than 5,000,000 tons.Many enterprises
Industry adopts stock to stack abraum salt at present, because taking a large amount of places so as to become the key factor of restriction enterprise development.Most of
The main component of industrial waste salt is sodium chloride, carries a large amount of organic or inorganic impurity secretly because of it and can not continue to make as raw material of industry salt
With.Because abraum salt belongs to poisonous and harmful substance, long-term stacking, not only waste land resource, and to environment structure grave danger.
Therefore, using suitable technique and equipment, abraum salt is carried out harmless treatment, inorganic salt resource therein is recycled,
Manufacturing enterprise and society are significant.
At present, domestic industry abraum salt is processed mainly following four method:
1st, desalinization of soil by flooding or leaching method
Industrial waste salt is washed off harmful soluble substance in abraum salt by washing or with detergent, this method is applied to process impurity
The few abraum salt of single and impurity content.
2nd, high temperature melting facture
Organic impuritiess in abraum salt salt slag are made to resolve into gas at high temperature, thus reaching the purpose removing organic impuritiess.?
In pyrolytic, directly brine waste can be thermally decomposed and be decomposed it is also possible to make solid crystal abraum salt form fused salt.?
Exist in decomposition nozzle easily block, wear and tear, the technical problem such as high temperature bond, stammerer, equipment corrosion.
3rd, high temperature cabonization oxidizing process
Its principle is Organic substance in abraum salt to be carried out decomposing carbonization and oxidation at high operating temperatures, makes Organic substance one in abraum salt
Partial thermal decomposition is escaping gas, and another part is changed into Solid organic carbon and aoxidizes formation ash.Technique used by the method at present
Using rake multilamellar carbonization furnace apparatus.The method is there is problems that the surface softening of carburizing temperature and salt is wayward, easily
Cause the bonding to carbonizing apparatus, affect continuous prodution.
4th, Method of Soda processed
Abraum salt salt slag is made saturated brine solution, is passed through ammonia and carbon dioxide under certain condition, form carbon
Sour hydrogen sodium, makes soda (sodium carbonate) through pyrolytic.The method can only produce soda.
Content of the invention
The problem existing for prior art, it is an object of the invention to provide a kind of industrial waste salt carbonization treatment method.
The process equipment implementing the method is by feeder, flash dryer, pneumatic tube predecomposition device, spouted bed carbide furnace
(in stove no gas distribution orifice), air heating incinerator, one-level catcher, two grades of catchers, circulating fan, aerator, remaining
Heat boiler, eluting column, pipe-line system and control system composition;
Abraum salt is sent into flash dryer by feeder and is dried, and removes the moisture in abraum salt;Dried abraum salt is through one
Level catcher trapping, and send into pneumatic tube predecomposition device and carry out heat resolve;Abraum salt after predecomposition is caught through two grades of catchers
Collection, send into spouted bed carbide furnace carry out carbonization treatment, the carbonization salt after carbonization as product overflow discharge out of the furnace (through cooling laggard
Enter postorder refining system to be refined);
Meanwhile, the tail gas after flash dryer dry materials is through one-level catcher, and sends into air by circulating fan
Heating incinerator carries out high temperature incineration;Air heats the hot-air that incinerator produces, and its major part sends into spouted bed through aerator
In carbide furnace, provide institute calorific requirement for material carbonization treatment, remainder through residual heat boiler for exchanging heat, then through eluting column drip washing heel row
Empty;Tail gas after spouted bed carbide furnace material carbonization enters pneumatic tube preheater, is that pneumatic tube predecomposition device is pre- to material
Resolution process provides institute's calorific requirement;Tail gas after pneumatic tube predecomposition implements material predecomposition, through two grades of catchers, enters flash distillation
Drying machine, provides heat for abraum salt dried.
In said method, described flash dryer is dried at a temperature of 250~350 DEG C;Described pneumatic tube divides in advance
Solution device predecomposition abraum salt is carried out at a temperature of 400~500 DEG C;In described spouted bed carbide furnace, material carbonization is in 500~750 DEG C of temperature
Carry out under degree, material carbonization time and carbonation rate are adjusted according to industrial waste salt constituent;Described air heating is burned
Stove carries out gas burning at 1000~1100 DEG C;After the described dedusting through eluting column, the exhaust temperature of emptying is below 150 DEG C.
Described pneumatic tube predecomposition device and spray-moving type carbide furnace can not limit according to impurity content combination in any in abraum salt
Compound mode, is beneficial to adjustment and decomposes and carbonization time and carburizing temperature.
Industrial waste salt carbonization treatment method of the present invention, removes abraum salt free moisture, in pneumatic tube in flash dryer
In preheater and spouted bed carbide furnace, abraum salt after drying is thermally decomposed and carbonization treatment.Organic substance in abraum salt passes through dry
Dry, decompose, after carbonization as carbonization salt output.High temperature incineration is carried out to the tail gas producing in technical process, burns the heat producing
Air provides heat mostly as system heat sources, and remainder changes its heat through waste heat boiler, more but arranges through eluting column chilling
Put, in case harmful gass produce, realize harmless discharge.
The invention has the beneficial effects as follows:
1st, the inorganic salt in industrial waste salt can be reclaimed by the present invention well, and the product after gained carbonization can be processed
