Dry quenching furnace coke discharging opening cooling control method

The invention discloses a dry quenching furnace coke discharging opening cooling control method. The dry quenching furnace coke discharging opening cooling control method comprises the following steps: (1) current coke discharging amount data of a dry quenching furnace is sent to a signal input circuit of a controller from a remote control chamber; (2) a temprature measuring box, a cooling box and a temperature feedback box are sequentially mounted on a rubber belt conveyor at the front part of the position of a coke discharging opening of the dry quenching furnace along the coke conveying direction from inside to outside; the three box bodies cover the coke conveyed on the rubber belt conveyor; (3) the coke is sensed by a temperature detection device mounted in the temprature measuring box; a temprature signal is sent to the signal input circuit of the controller; after the temprature signal is subjected to comparison operation of a microprocessor, a signal is output to control the opening degree of a flow adjusting control valve so that the water quantity sprayed by a cooling water nozzle in the cooling box is controlled; (4) the coke is conveyed to the temperature feedback box by the rubber belt conveyor and is sensed by a temperature detection device in the temperature feedback box; a temperature signal is transmitted to the signal input circuit; after the comparison operation of the microprocessor, the cooling water quantity control signal which is output in advance is supplemented and corrected, and the opening degree of the flow adjusting control valve is readjusted.
