The course of work of the utility model is as follows:
Under the conditions of vacuumizing, when operating pressure reduces in tower, liquid storage point material is a large amount of everywhere in tower reactor and rectifying column
Evaporation, the upward motive force of gaseous phase materials increase position of floating body, and floating body becomes smaller with the spacing of corresponding gas-liquid distribution hole, in tower
Pressure drop becomes larger, and since the pressure of tower top is remained stable by relevant device control, the vacuum degree at tower reactor can become smaller, and causes
Liquid material evaporation rate reduces, and then slows down the reduction rate of operating pressure in tower, avoids the unexpected reduction of tower pressure interior force；When
When operating pressure increases in tower, liquid storage point material evaporation amount is reduced everywhere in tower reactor and rectifying column, the upward promotion of gaseous phase materials
Power reduces, and position of floating body reduces, and floating body becomes larger with the spacing of corresponding gas-liquid distribution hole, and tower pressure drop becomes smaller, due to tower top
Pressure is remained stable by relevant device control, therefore the vacuum degree at tower reactor can become larger, and leads to liquid material evaporation rate liter
Height, and then slow down the increase rate of operating pressure in tower, the unexpected raising of tower pressure interior force is avoided, achievees the effect that pressure stabilizing.
The utility model is good to the voltage regulation result of rectifying column, can be in tower reactor, tower top and tower on other liquid storage points
Portion's setting.
