Description
Technical field
The mass transfer apparatus that the utility model is related to be used in chemical industry is a kind of mass transfer of chemical industry mass transfer separation column plate
Element, specially a kind of calotte with floating regulating device.
Background technology
Column plate is used widely as important mass transfer apparatus element in chemical separating operation.Vertical sieve tray is
A kind of cocurrent jet tray developed in 1963-1968 by Mitsui Ship-building Company, core element are to be used on column plate
Vertical sieve tray calotte.Since its gas phase is continuous, solution dispersion, has the advantages that processing capacity is big, pressure drop is low etc., applied quickly
Into chemical production field.The calotte is studied by domestic more mechanisms, proposes modified calotte one after another, and in work
Industry application aspect also achieves remarkable effect.
Vertical sieve tray is made of bottom plate and calotte, and circular plate hole is provided on bottom plate, and plate hole is arranged above circle
Calotte, calotte are made of top plate, side wall, supporting leg three parts.Supporting leg plays connection calotte and bottom plate, while supporting leg is controllable
The distance of calotte lower end and bottom plate controls the bottom gap of calotte；Side wall has side-wall hole；Top plate and side wall composition calotte are whole.
Traditional vertical sieve tray operation lower limit is higher, and operating mode load is susceptible to leakage when reducing, and operating flexibility range is caused to subtract
Small, mass-transfer efficiency declines.
Utility model content
In view of the deficiencies of the prior art, the technical issues of the utility model intends to solve is to provide a kind of band floating adjusting dress
The calotte set.
The technical solution that the utility model solves the technical problem is to provide a kind of calotte with floating regulating device,
Including top plate, side wall and supporting leg；The upper end of the top plate and side wall connects；It is closed by top plate calotte upper end；The side wall is
Cylindrical shape；The side wall upper part is evenly distributed with several side-wall holes；The lower part of the side wall and the top of supporting leg connect；The supporting leg
Lower end connect with bottom plate；There is bottom gap between the lower end and bottom plate of the side wall；The position that the bottom plate corresponds to calotte center has
Circular plate hole；It is characterized in that the calotte further includes floating regulating device；The floating regulating device is located at interior；Institute
Floating regulating device is stated to be made of floating adjustable plate and at least three barbs；The upper end of the floating adjustable plate and barb, which is fixed, to be connected
It connects, barb is uniformly distributed on floating adjustable plate；The lower end of barb passes through plate hole and hooks bottom plate lower surface, barb and bottom plate
It is not fixed connection；The diameter of floating adjustable plate is less than the diameter of side wall, is more than the diameter of plate hole.
Compared with prior art, the utility model advantageous effect is：
(1) this calotte increases floating regulating device, can be floated up and down in calotte according to the variation of gas phase flow rate；Low
When load condition, by plate hole Lai gas phase flow rate reduce, floating regulating device declines automatically, makes have foot by the gas phase of plate hole
Enough gas velocity, it is sufficient to promoted by bottom gap come liquid phase increase operating flexibility range so as to avoid the generation of leakage, raising
Mass-transfer efficiency, optimizes performance of the calotte in low workload, the scope of application of calotte is further expanded, for work
The larger occasion of load variations has better adaptability.
(2) applied widely, it is simple to manufacture, transformation is convenient, expands the application range of calotte.

Specific implementation mode
Specific embodiment of the utility model is given below.Specific embodiment is only used for being further described this practicality newly
Type does not limit the application scope of the claims.
The utility model provides a kind of calotte (referring to Fig. 1-2, abbreviation calotte) with floating regulating device, including top plate
1, side wall 2 and supporting leg 4；The top plate 1 is connect with the upper end of side wall 2；It is closed by top plate 1 calotte upper end；The side wall 2 is circle
Tubular；2 top of the side wall is evenly distributed with several side-wall holes 3；The lower part of the side wall 2 is connect with the top of supporting leg 4；The branch
The lower end of leg 4 is connect with bottom plate 6；There is bottom gap 5 between the lower end and bottom plate 6 of the side wall 2；The bottom plate 6 corresponds to calotte center
Position have circular plate hole 8；It is characterized in that the calotte further includes floating regulating device；The floating regulating device is located at side
Inside wall 2；The floating regulating device is made of the uniformly distributed barb 9 of circular floating adjustable plate 7 and at least three；The floating
Adjustable plate 7 is fixedly connected with the upper end of barb 9, and barb 9 is uniformly distributed on floating adjustable plate 7；The lower end of barb 9 passes through bottom
Plate hole 8 on plate 6 simultaneously hooks 6 lower surface of bottom plate, and barb 9 need not be fixedly connected with bottom plate 6；The diameter of floating adjustable plate 7 is small
In the diameter of side wall 2, it is more than the diameter of plate hole 8；
The number of the barb 9 preferably 3 or 4；
The operation principle and workflow of calotte of the utility model with floating regulating device be：When normal work, come from
The gas phase of 8 lower section of plate hole blows floating adjustable plate 7 across plate hole 8.Due to the limitation of barb 9, floating adjustable plate 7 can only be transported upwards
Dynamic certain distance, floating adjustable plate 7 will form difference in height with plate hole 8, and gas phase is after plate hole 8 in the effect of floating adjustable plate 7
Under be deflected into inside calotte and continue to move upwards in calotte with the liquid phase formation gas-liquid mixture from bottom gap 5, gas-liquid
Mixture finally hits after top plate 1 that baffling is sprayed from side-wall hole 3 outside calotte again, completes entire workflow.
The utility model does not address place and is suitable for the prior art.
