Abstract
This invention relates to the field of spray structure technology, and more particularly to a circulating ammonia water spraying device and control method for a coke oven gas negative pressure pipeline. The device includes a secondary pipe connected to the gas pipeline and a sealing guide sleeve disposed opposite to the secondary pipe. The on / off state of the secondary pipe and the sealing guide sleeve is controlled by a control valve. A nozzle structure is disposed within the sealing guide sleeve, and the nozzle structure is connected to an external ammonia water pipeline via a movable pipe. This invention effectively solves the drawback of traditional spraying devices requiring the cessation of gas delivery during maintenance. It allows the nozzle structure to be isolated from the gas pipeline while the gas pipeline is continuously delivering gas, thereby maintaining good sealing of the gas pipeline and preventing external air from entering. This facilitates direct disassembly of the nozzle structure in this state, improving the convenience of maintenance work and ensuring continuous and safe production.
