Tandem type ammonia synthesis tower with pressure autonomous regulation and control function

The invention discloses a tandem ammonia synthesis tower with a pressure autonomous regulation function, the tandem ammonia synthesis tower comprises an ammonia synthesis tower body, the outer wall of a feeding pipe is fixedly connected with a fixed block, and a first groove is formed in the fixed block. A first rotating plate is arranged at one end of a driving shaft, a barrier plate is arranged on the outer wall of a second movable plate, so that the gas inlet and outlet amount of a vent hole can be changed, and as gas is continuously reacted in the tandem ammonia synthesis tower, when a thermocouple and an electric heater are used for a period of time, the thermocouple and the electric heater are gradually lost, and the temperature of the thermocouple and the electric heater is reduced. According to the device, the gas flux can be adjusted, so that the gas reaction consumption is in direct proportion to the gas inflow, the gas pressure in the tandem type ammonia synthesis tower cannot be increased, and the
