Description

A kind of vertical sieve tray calotte with skirt

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 skirt.

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 skirt 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 skirt Calotte, including calotte top board and cap side walls；The upper end attachment cap cowl top panel of cap side walls, cap side walls top is provided with calotte side Hole；It is characterized in that the calotte also includes skirt；The skirt is made up of skirt side wall and skirt top board；The skirt top board is Annular plate, the inner circle of skirt top board are connected with the lower side of cap side walls, the cylindrical and skirt sidewall upper of skirt top board Connection；Skirt side wall lower ends are connected with level tray plate upper surface；Calotte is left between cap side walls lower end and level tray plate Bottom gap；Skirt side wall is provided with the perpendicular gap of skirt；The perpendicular gap of skirt is evenly distributed on the wall of skirt side, is highly skirt overall height 0.1-0.8, and the thickness of the split-phase liquid being not less than on level tray plate.

Compared with prior art, the beneficial effects of the utility model are：The skirt of the calotte design instead of conventional caps The supporting leg of cover, both plays support and interconnection function, plays drain effect again.The calotte solves conventional vertical under liquid-phase separation operating mode The liquid that sieve plate column plate can not make the density of split-phase different all carries out the problem of gas-to-liquid contact mass transfer in calotte.The calotte Suitable for the operating mode of liquid-phase separation in knockout tower of mass transfer, it is simple to manufacture, transformation is convenient, mass transfer effect improves obvious, economic benefit Significantly.

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 skirt (referring to Fig. 1-3, abbreviation calotte), bag Include calotte top board 1, cap side walls 3 and skirt 4；3 top of the cap side walls is provided with calotte side opening 2, the connection of 3 upper end of cap side walls Calotte top board 1, leaves calotte bottom gap 8 between 3 lower end of cap side walls and level tray plate 9；The skirt 4 is by 6 He of skirt side wall Skirt top board 5 is constituted；The skirt top board 5 is annular plate, the inner circle of skirt top board 5 and the lower side company of cap side walls 3 Connect, the cylindrical of skirt top board 5 is connected with 6 upper end of skirt side wall；Wall 6 lower end in skirt side is connected with 9 upper surface of level tray plate；Skirt Seat side wall 6 is provided with the perpendicular gap 7 of at least three skirts；The perpendicular gap 7 of skirt is evenly distributed on skirt side wall 6, and the present embodiment is to be based on DN80 calottes, the quantity of the perpendicular gap 7 of skirt is 10, and size is 5mm × 40mm, is highly the 0.1-0.8 of 4 overall height of skirt, And the thickness of the split-phase liquid being not less than on level tray plate 9；0.05-0.5 of the height of skirt 4 for cap height.

There is this utility model the operation principle and workflow of the vertical sieve tray calotte of skirt to be：Work as level tray There is split-phase in the liquid phase gathered on plate 9, out of phase liquid can be entered inside skirt 4, in skirt 4 by the perpendicular gap 7 of skirt Portion's liquid phase is entered inside calotte by calotte bottom gap 8, contact in calotte internal mix with the gas phase below column plate, mass transfer, Heat transfer, gas-liquid mixture finally sprayed by calotte side opening 2, and liquid is fallen down on level tray plate 9 under gravity, gas after Last layer column plate is gone in continuous rising.

This utility model is not addressed part and is applied to prior art.
