Description
Technical field
The present invention relates to technical field of chemical, and in particular to a kind of plate distillation column provided with elastic float valve.
Background technology
Rectification process is the typical unit operation that mutually soluble liquids mixture is separated in Chemical Manufacture, and its essence is multistage is steamed
Evaporate, i.e., it is under a certain pressure, different using the boiling point or saturated vapor pressure of mutually soluble liquids mixture each component, make light component (boiling
The relatively low or higher saturated vapor pressure component of point) vaporization, condense, make in gas phase through the vaporization of multiple Partial Liquid Phase and partial gas phase
Light component and liquid phase in heavy constituent concentration gradually rise, so as to realize separation.
Typical rectifying device is continuous rectification apparatus, including rectifying column, reboiler, condenser etc..Rectifying column has board-like
Tower and two kinds of main Types of packed tower.Float valve plate column is a kind of widely used gas-liquid mass transfer (contact) equipment, in the prior art, when
When valve plate is in running order, float valve can be constantly on extreme higher position under the impact of air-flow, i.e., will not on float downward
It is dynamic, so the elastic operation space of float valve is smaller, therefore cause float valve relatively low to the separating effect of liquid phase.
The content of the invention
The invention aims to overcome deficiency of the prior art, there is provided a kind of board-like rectifying provided with elastic float valve

Compared with prior art, beneficial effects of the present invention are：（1）It is multiple due to being provided between support chip and column plate
Spring, so adding the elastic operation space of float valve, i.e. float valve can effectively be fluctuated, and steam is played more with this
Good separating effect so that what gas phase was distributed in tower body is more uniformly distributed；（2）Liquid from reboiler enters in tower reactor
In one cavity, a part is exported from raffinate as bottom product and discharged, and another part can mix the liquid flow down from tower body
Into in reboiler, to improve the concentration into the liquid of reboiler as far as possible, the separation energy of reboiler is played to greatest extent
Power, the concentration of bottom product is further reduced, improve the separative efficiency of rectifying column；（3）Entered by the shape to tower seat and structure
Row changes, and effectively increases its stable degree when being supported to rectifying column；（4）The liquid distribution of entrance is uniform, and fluid is in column plate
In distribution it is good, mass-transfer efficiency is higher, and mass transfer loss in efficiency is small, and stable operation type is good.
