The region of liquid increases, and the contact area of superheated liquid and microprotrusion increases, and more superheated liquids are vaporized into minute bubbles, with into
One step inhibits the severe degree of boiling, keeps the boiling process in reboiler steady.
The beneficial effects of the present invention are: inhibiting the severe degree of the boiling in reboiler, bumping is avoided, is made in reboiler
Boiling process is steady, reduces the impact that reboiler is subject to.
Detailed description of the invention
Fig. 1 shows reboiler schematic diagram；
Fig. 2 shows impeller schematic diagrams.
Specific embodiment
With reference to the accompanying drawings, the function that the structure of this system is described in detail and is realized.
A kind of reboiler comprising shell 1, the tower bottom liquid entrance 2 set on 1 lower part of shell, the steam set on 1 top of shell
Outlet 3 is used for set on shell 1 inside by the heat exchanger tube 4 of the tower bottom liquid ebuillition of heated in reboiler shell to vaporization, with
And pressure sensor 6 and controller,
The reboiler further includes turbine assembly, and the turbine assembly includes turbine 51, and passes through one with the turbine 51
The impeller 53 that electromagnetic clutch 52 connects, in which: the turbine 51 is set at steam (vapor) outlet 3, is discharged by steam (vapor) outlet 3
Steam drives and rotates, and then impeller 53 connected to it is driven to rotate；The impeller 53 is set to the underface of turbine 51, and
It is fully immersed in tower bottom liquid, the fan blades 531 of impeller 53 is equipped with multiple microprotrusions, and the fan blades 531 is by left half fan blades
The combined type fan blades for connecting and nesting together by spring with half fan blades of the right side；
Tower bottom liquid, which enters, extremely boils with the heat exchanger tube 4 heat exchange in reboiler shell and is evaporated, and steam is discharged simultaneously from steam (vapor) outlet 3
Turbine 51 and/or impeller 53 is driven to rotate, disturbance, the microprotrusion stirred on superheated liquid, with fan blades 531 connect when impeller 53 rotates
The part superheated liquid of touching is vaporized into minute bubbles at microprotrusion, to inhibit the accumulation of superheated liquid, so that at tower bottom liquid
In the state steadily boiled；
The pressure sensor 6 is set on the upside of the inner wall of reboiler shell 1, for detecting the air pressure pressure in reboiler shell 1
The size of power；
The controller is configured as:
When first threshold of the atmospheric pressure lower than setting, controls the electromagnetic clutch 52 and disconnect turbine 51 and impeller 53
Between connection；
When the atmospheric pressure is more than first threshold, the electromagnetic clutch 52 is controlled with the first degree of engagement and connects the whirlpool
Wheel 51 and the impeller 53 make the revolving speed of impeller 53 be less than the revolving speed of turbine 51, avoid 51 revolving speed of impeller excessive and cause to overheat
The splashing of liquid；
Quantity of steam when the atmospheric pressure is more than the second threshold higher than first threshold namely in reboiler shell increases
When, the electromagnetic clutch 52 is controlled with the second degree of engagement and connects the turbine 51 and the impeller 53, makes the rotation of impeller 53
Turn synchronous with the holding of turbine 51, since revolving speed increases, the fan blades 531 on impeller 51 stretches under the action of bigger centrifugal force
