There are some researches show, Organic substance contained in coking chemical waste water can decompose completely when 400 DEG C.At present, a patent:
" a kind of Processes and apparatus utilizing converter dust-removing high-temperature flue gas pyrolysis coking chemical waste water " (application number or the patent No.:
CN201410206286.9, applicant or patentee: Laiwu Iron & Steel Group Co., Ltd), its disclose the method use turn
Stove high-temperature flue gas Treatment of Wastewater in Coking, but, Treatment of Wastewater in Coking amount is less, simultaneously need to catalyst and certain equipment are thrown
Money, cost increases.
Summary of the invention
It is an object of the invention to, for solving the method for existing Treatment of Wastewater in Coking is existed drawbacks described above, the present invention
Provide a kind of method utilizing sintering process Treatment of Wastewater in Coking；The method utilizes coking chemical waste water to have sticking feature, will
It is applied to sintered compound granulation link, both can direct Treatment of Wastewater in Coking, save the cost of Treatment of Wastewater in Coking, be conducive to again
The granulation of batch mixing, also a saving water resource simultaneously.The method comprises the following steps:
Step 1 is by sintering mixing material, and flux and coke powder or coal dust proportionally carry out dispensing；
Dispensing after proportioning is good in step 1 is delivered to the first cylindrical mixer by step 2, meanwhile, sprays coking and gives up
Water, carries out mixing granulation for the first time in described first cylindrical mixer, obtains mixing granulation material for the first time；
Described first time mixing granulation material in step 2 is delivered in the second cylindrical mixer, meanwhile, again by step 3
Spray coking chemical waste water, described second cylindrical mixer carries out second time mixing granulation, obtain second time mixing granulation material；With
Time, control the amount of coking chemical waste water, control the total moisture content of described second time mixing granulation material at 5%-10%；
Described second time mixing granulation material is carried out cloth and lights a fire by distributing device by step 4, carries out oxygen-enriched burning simultaneously
Knot；
In coking chemical waste water described in step 5, Organic substance poisonous, difficult degradation passes through the high temperature of generation in sintering process, splits
Solve, and aoxidize, generate non-toxic gas and enter sintering flue gas.Meanwhile, by sintering the high temperature sintering ore deposit of output, carry out crushing,
Cooling processes.
Described coking chemical waste water, in sintering process, by utilizing the high temperature produced in sintering process, cracks, and oxygen
Change, generate non-toxic gas and enter sintering flue gas, it is not necessary to realized by the technique of this high cost of biochemical treatment, protect
Environment, reduces pollution level.
It is an advantage of the current invention that: on the basis of existing sintering process, will mixing granulation and second time mixing for the first time
Water required in pelletization changes coking chemical waste water into, has saved water resource, solves iron and steel enterprise's coking chemical waste water and pollutes environment
And use the high cost that brought of biochemical treatment and the problem for the treatment of effeciency difference；Make use of coking chemical waste water viscosity, enhance
Sintered compound is pelletized, and improves the breathability of sintering process, adds the productivity of sintering deposit.The cracking of coking chemical waste water, aoxidizes institute
The condition needed need not additionally use equipment and investment, at the ingenious high temperature utilizing generation in existing sintering process and oxidation environment
Reason coking chemical waste water, reduces processing cost.
