AI Technical Summary
The existing ammonia spraying device for coke oven bridge pipes cannot effectively atomize and spray evenly, resulting in insufficient contact between ammonia and raw coal gas, and thus failing to achieve a cooling effect.
A coke oven bridge pipe ammonia spraying device was designed. It adopts an inner core with a straight ammonia water channel at the center and multiple inclined channels on the outside to form a spiral channel. The ammonia water rotates, mixes, and impacts in the mixing chamber. Combined with the cylindrical mixing chamber and inverted conical outlet of the shell, uniform atomized spraying is achieved. An ultrasonic flow meter is equipped to monitor the flow rate for easy cleaning and maintenance.
It achieves uniform atomization and spraying of ammonia water, ensuring full contact with raw coal gas for a cooling effect, while reducing the risk of blockage, extending the spraying cycle, and facilitating installation and maintenance.
