Abstract
The utility model discloses a vertical sieve plate tower board calotte with erect crack, including calotte roof and calotte lateral wall, the upper end and the calotte roof connection of calotte lateral wall, open on calotte lateral wall upper portion has the calotte side opening, the lower extreme and the column plate horizontal plate of its characterized in that calotte lateral wall are connected, open the lower part of calotte lateral wall has the lateral wall to erect the crack, and the lateral wall erects crack evenly distributed on the calotte lateral wall, the lateral wall erect height <= the calotte lateral wall in crack the totality height 0.45 to be not less than the thickness of the phase separating liquid on the column plate horizontal plate. The calotte has been solved under the liquid phase phase separating operating mode the liquid that density is different that traditional vertical sieve plate tower board can not make the phase separating and has all been got into the problem of carrying out the gas -to -liquid contact mass transfer in the calotte.
Description
Technical field
This utility model is related to chemical industry mass transfer apparatus, is a kind of mass transfer component of chemical industry mass transfer separation column plate, specially
A kind of vertical sieve tray calotte with perpendicular gap.
Background technology
Column plate is widely applied in chemical separating operation as important mass transfer apparatus element.Vertical sieve tray
It is a kind of cocurrent jet tray developed in 1963-1968 by Mitsui Ship-building Company.As its gas phase is continuous and liquid phase
Dispersion, with disposal ability is big, the low advantage of pressure drop, is applied in chemical production field quickly.Domestic Duo Jia mechanisms are to this
Column plate is studied, and proposes modified model column plate one after another, and remarkable effect is also achieved in terms of commercial Application.
Column plate is made up of horizontal plate and vertical sieve tray calotte.Calotte on conventional vertical sieve plate column plate is mainly by three part groups
Into including calotte supporting leg, cap side walls, calotte top board, calotte supporting leg plays connection calotte and column plate, and cap side walls are opened
Hole, calotte top board are connected with cap side walls.There is liquid layer on level tray plate when traditional vertical sieve tray calotte works, liquid passes through
Bottom gap between calotte and level tray plate into inside calotte with column plate below the gas phase that rises carry out gas-to-liquid contact mass transfer, it is right
The operating mode only big liquid of bottom density of liquid split-phase can carry out gas-to-liquid contact mass transfer into calotte on the column plate, and upper strata is close
The little liquid of degree can not carry out gas-to-liquid contact mass transfer into calotte, cause column plate cisco unity malfunction.
Utility model content
For the deficiencies in the prior art, the technical problem that this utility model is intended to solve is to provide a kind of hanging down with perpendicular gap
Straight sieve plate column plate calotte.The calotte can realize that the light phase split-phase liquid in the upper strata of column plate and lower floor's heavy phase split-phase liquid can be entered
Gas-to-liquid contact mass transfer is carried out in calotte.
This utility model solves the technical scheme of the technical problem and is to provide a kind of vertical sieve tray with perpendicular gap
Calotte, including calotte top board and cap side walls；The upper end of cap side walls is connected with calotte top board, and cap side walls top is provided with calotte
Side opening；It is characterized in that the lower end of cap side walls is connected with level tray plate；The bottom of cap side walls is provided with the perpendicular gap of side wall, side wall
Perpendicular gap is evenly distributed in cap side walls, and the 0.45 of the overall height of the height≤cap side walls of the perpendicular gap of side wall, and be not less than
The thickness of the split-phase liquid on level tray plate.
Compared with prior art, the beneficial effects of the utility model are：The calotte eliminates the supporting leg of traditional calotte, cap
Cover side wall is directly connected to level tray plate.The calotte solves conventional vertical sieve plate column plate under liquid-phase separation operating mode and can not make
The different liquid of the density of split-phase all carries out the problem of gas-to-liquid contact mass transfer in calotte.The calotte is applied to knockout tower of mass transfer
The operating mode of interior liquid-phase separation, is simple to manufacture, and transformation is convenient, and mass transfer effect improves obvious, remarkable in economical benefits.

Figure；(in figure：1st, calotte top board；2nd, calotte side opening；3rd, cap side walls；4th, the perpendicular gap of side wall；5th, level tray plate)
Specific embodiment
Specific embodiment of the utility model is given below.Specific embodiment is only used for further describing this practicality newly
Type, does not limit the application scope of the claims.
This utility model provides a kind of vertical sieve tray calotte with perpendicular gap, including calotte top board 1 and calotte side
Wall 3；The upper end of cap side walls 3 is connected with calotte top board 1, and the lower end of cap side walls 3 is connected with level tray plate 5；Cap side walls 3
Top is provided with calotte side opening 2, and the bottom of cap side walls 3 is provided with the perpendicular gap 4 of at least three side walls, and wall perpendicular gap 4 in side is evenly distributed on cap
On cover side wall 3, the 0.45 of the overall height of the height≤cap side walls 3 of the perpendicular gap 4 of side wall, and be not less than on level tray plate 5
Split-phase liquid thickness.The calotte based on DN80 in the present embodiment, the quantity of the perpendicular gap of side wall is 16, size be 4mm ×
40mm。
Operation principle of this utility model with the vertical sieve tray calotte for erecting gap and workflow are：Work as level tray
There is split-phase in the liquid phase gathered on plate 5, out of phase liquid can be entered inside calotte by the perpendicular gap 4 of side wall, and from tower
Gas phase below plate is finally sprayed by calotte side opening 2 in the contact of calotte internal mix, mass transfer, heat transfer, gas-liquid mixture, and liquid exists
Fall under under action of gravity on level tray plate 5, gas continues rising and goes to last layer column plate.
This utility model is not addressed part and is applied to prior art.
