Description
Technical field
The utility model belongs to coker, especially for the equipment of coal gas primary cooler waste heat recovery.
Background technology
Coking industry is an important energy production division, is again the big power consumer.China's coking production process energy consumption is 180～200kg mark coal/t.With regard to the heat that the coke oven product is taken out of, the sensible heat of red-hot coke occupies first, and the sensible heat of raw coke oven gas occupies second, and both totals account for 65%～75% of the total quantity of heat given up of coke oven.The available energy that raw coke oven gas is taken out of accounts for coke oven and always exports 12～18% of available energy; Major part is transferred in the cooling water of cyclic ammonia water and primary cooler in this process; Be not utilized effectively, therefore, to the waste heat recovery of gas primary cool system; Increase economic efficiency to the coke-oven plant is energy-saving and cost-reducing, have important effect.
The utility model content
The deficiency that does not make full use of for the waste heat that overcomes raw coke oven gas in the existing coal gas primary cooler; The device that the utility model provides a kind of coal gas primary cooler residual heat integrative to utilize; The device of this coal gas primary cooler residual heat integrative utilization can be used for heating with the waste heat of raw coke oven gas winter, is used for refrigeration summer.
The utility model solves the technical scheme that its technical problem adopted: the device that a kind of coal gas primary cooler residual heat integrative utilizes; It is characterized in that: coal gas primary cooler is divided into waste heat recovery section, recirculated water section, water at low temperature section from top to bottom; The water inlet of waste heat recovery section upper and lower is connected with return pipe with the feed pipe of heating system through the pipeline that heating water supply transfer valve and heating backwater transfer valve are housed respectively; The water inlet of waste heat recovery section upper and lower is connected with the intake-outlet of refrigeration machine through another road pipeline that refrigeration machine hot water transfer valve and refrigeration machine backwater transfer valve are housed respectively, and the cooling water outlet of refrigeration machine and water return outlet are imported and exported with the water at low temperature section of primary cooler and linked to each other.
Described heating system is equipped with hot water circulating pump in the loop.
The concrete method of operation of the device of coal gas primary cooler residual heat integrative utilization is: open heating water supply transfer valve and heating backwater transfer valve in the winter time; Close refrigeration machine hot water transfer valve and refrigeration machine backwater transfer valve; The gas temperature that gets into from the primary cooler top in the waste heat recovery section is reduced to 70～75 ℃ by 82～85 ℃; The heating circulating hot water is heated to about 65 ℃ by about 55 ℃, supplies with heating system through hot water circulating pump.
Close heating water supply transfer valve and heating backwater transfer valve in summer; Open refrigeration machine hot water transfer valve and refrigeration machine backwater transfer valve; The gas temperature that the waste heat recovery section gets into from the primary cooler top is reduced to 70～75 ℃ by 82～85 ℃; Kind of refrigeration cycle hot water is heated to about 75 ℃ the water-heating cooling machine of supplying with by about 65 ℃, and refrigeration machine is reduced to 16 ℃ with the recirculated water of water at low temperature section from 23 ℃ and turns back to primary cooler through the Cold water supply pipeline, carries out heat exchange with coal gas; Coal gas is cooled to 23 ℃, flows out primary cooler and remove air blast.
The beneficial effect of the utility model is that this equipment has realized that the primary cooler residual heat integrative makes full use of, and is used for supplying heating system winter, and summer, refrigeration can improve the efficient of primary cooler, had reached energy saving purposes.
