Efficient rectifying tower for chemical production

Abstract

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.

Description

technical field [0001] The invention relates to a rectification tower, in particular to a high-efficiency rectification tower for chemical production. Background technique [0002] Rectification is usually carried out in a rectification tower, and the gas-liquid two-phase contacts through countercurrent to perform interphase heat and mass transfer, the volatile components in the liquid phase enter the gas phase, and the less volatile components in the gas phase transfer to the liquid phase, so Almost pure volatile components can be obtained at the top of the tower, and almost pure low-volatile components can be obtained at the bottom of the tower. [0003] Existing high-efficiency rectification towers lack explosion-proof functions. During the rectification process, if the internal pressure of the rectification tower is too high, an explosion may occur, which seriously affects the safety of the rectification tower during use. Therefore, we improve this and propose a high-ef...
