Automatic ignition control system of diffusing of coke oven

The embodiment of the utility model discloses automatic ignition control system of diffusing of coke oven, it diffuses the device to include by the nitrogen gas air supply, diffuse the automation that air circuit breaker and pneumatic cylinder formed. During the upper pressure limit that exceed to set up at gas collection pipe inner pressure, diffusing the nitrogen gas of air circuit breaker in with the nitrogen gas air supply through control and carrying to one of pneumatic cylinder to advance / gas vent, pneumatic cylinder opens under the nitrogen pressure effect the flap valve realizes that the raw coke oven gas diffuses automatically, when the collecting main pressure is less than the lower limit value, then diffuse the nitrogen gas of air circuit breaker in with the nitrogen gas air supply through control and carry to another of pneumatic cylinder to advance / gas vent, accomplish closing of flap valve. The utility model discloses power is regarded as with nitrogen gas to implementation, accomplishes the
