The efficient rectifying tower for chemical production comprises a tower body assembly; the tower body assembly is composed of a tower body, a feeding pipe, a discharging pipe and a first control valve; a stirring shaft assembly is arranged in the tower body, and the stirring assembly is composed of a stepping motor, a protection box, two transmission gears, two rotating shafts and a plurality ofstirring blades; a protection assembly is arranged at the top of the tower body and composed of a protection pipe, an air leakage hole, a connecting rod, a push plate, a spring, a piston, an electromagnetic valve, an exhaust pipe, a supporting plate, a normally-open button switch and a buzzer. If the internal pressure of the tower body is too large, the redundant pressure pushes the piston to rise, the piston pushes the push plate to rise through the connecting rod and extrudes the normally open button switch at the moment, the buzzer and the electromagnetic valve are powered on to work, thenthe buzzer makes a sound to give an alarm at the moment, and the electromagnetic valve is switched on, so that the redundant gas in the tower body can be exhausted through the exhaust pipe, and the explosion-proof function is achieved.
