Steam fire extinguishing safety interlocking device

The utility model relates to the technical field of chemical fiber production, in particular to a steam fire extinguishing safety interlocking device which comprises an electrostatic oil removing machine, a textile production line, an exhaust fan, an air pipe, a temperature monitoring device, a steam conveying pipe, a spray head and a steam generator. The first electric valve has an opening state and a closing state, when the temperature is lower than a set value, the first electric valve is in the opening state, and when the temperature of the air pipe exceeds the set value, the first electric valve is converted into the closing state; the temperature monitoring device is arranged in the air pipe to monitor the internal temperature of the air pipe in real time, when the temperature exceeds a preset value, the steam generator conveys steam to the steam conveying pipe, then the steam is conveyed into the air pipe through the spray head, and the purpose of rapid flame retardance is achieved through steam isolat
