Abstract:

The energy saving and discharge reduction technology between high-capacity coke oven and stamp-charging coke oven was analyzed. After the disposal mode of high pressure ammonia liquor injection in single collecting main and the combination of de-dusting charging car and stationary bag-house unit for 7m high coke oven was adopted, the gas discharged can meet the requirement of environmental protection. The PROven system is used for 7.63m high coke oven and in combination with the charging car, its effect is equivalent to high pressure ammonia liquor injection + stationary bag-house unit. If 6.25m stamp-charging coke oven adopts high pressure ammonia liquor injection device, double U shape emission transfer car, oven door sealing device and oven end emission suction device on pusher side, the emission escaped can be controlled to maximum extent.
