Abstract
A high performance combined porous medium bubble cover tower board, which organically combines the two transmission mediums of injecting and bubbling in heat transmission mode. The inside of the tower is arranged with a lateral tower board arranged in an open manner with air rising hole, the upper part of each of the air rising hole is all arranged with a liquid rising ring, the outside of which is arranged with an injection cover, the injection cover itself is not arranged with holes, the top end is not arranged with block board, and a bottom gap is arranged on the injection cover and the tower board. A segment of porous medium or padding is filled between the outmost cover body and the injection cover, the outer layer cover body part below the filling layer is arranged in uniform with exhaust holes, and a bottom gap is also arranged between the cover body and the tower board. The main transmission medium is bubbles when the air speed is small in real operation, the two forms of the infection and the bubble mutually exist when the air speed is large. The operation burden area of the utility model is large compared with current tower board, the amount of the carried fog foam evidently reduces, and the transmission efficiency is also greatly improved, thus has higher maneuverability and flexibility in real operation.
Description
Affiliated technical field
What the utility model designed is the high capacity tray in the used plate column of gas-liquid mass transfer isolation technics in the industries such as oil refining, chemical industry, light industry.
Background technology
The gas-liquid mass transfer isolation technics has a wide range of applications in industrial production, comprises chemical engineering unit operations such as distillation, absorption, stripping, and these operations are carried out in tower mostly.Plate column occupies an important position in tower as traditional mass transfer separation equipment, and column plate then is the most basic in the plate column, most important parts.After entering nineteen nineties, be the big flux that adapts to increasing major diameter tower, high efficiency requirement, the breakthrough of plate column technology causes the interest that people are new again.
Current the most frequently used column plate has sieve tray, valve plate, bubble column etc., and these column plates mainly carry out mass-and heat-transfer by gas bubbling in liquid phase.Yet these column plate disposal abilities are little, and pressure drop is big.Valve tower applied load wherein is low, when gas phase velocity is big, because of blowing sky plate efficiency is reduced easily.In recent years the vertical sieve plate column of Chu Xianing is by carrying out mass-and heat-transfer with the liquid injection for drop, than traditional column plate obvious improvement is being arranged all aspect disposal ability and the efficient, but limit for height under the applied load of column plate, efficient are still not high enough, and commercial Application only limits to specified conditions.
Summary of the invention
For the use that overcomes present plate column column plate is subjected to load limit, and the problem that mass-transfer efficiency is not high enough, the utility model provides a kind of high performance combined type column plate, and this column plate not only can enlarge the applied load scope of tower, can also improve the mass-transfer efficiency of column plate effectively.
The scheme of the utility model technical solution problem is: will spray with two kinds of mass-and heat-transfer matter of bubbling mode and make up, in tower, load onto and have the horizontal column plate of air rising hole, the top of each air rising hole all rises pendular ring, there is jet cover in its outside, not perforate of jet cover itself, the top is not baffled, and crack, the end is arranged between jet cover and the column plate.Fill one section porous media or filler between outermost cover body and the jet cover, the part of outer cover body below packed layer has uniform steam vent, also has crack, the end to exist between cover body and the column plate.In the practical operation, when gas speed was little, main mass transfer mode was a bubbling, when gas speed is big, sprayed and two kinds of form coexistences of bubbling.
It is big that the utility model and existing column plate are compared the operational load scope, and mist entrainment obviously reduces, and mass-transfer efficiency also improves greatly, has higher operability and flexibility in practical operation.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the open-cellular form schematic diagram of air rising hole.
Specific embodiments
Among Fig. 1, in tower body (1), load onto horizontal column plate (7), have many row's air rising holes (8) on the column plate, the top of each air rising hole all rises pendular ring (6), and there are jet cover (5), not perforate of jet cover itself in its outside, the top is not baffled, and crack, the end is arranged between jet cover and the column plate.Fill one section porous media or filler (4) between outermost cover body (2) and the jet cover, porous media can be made with the particles sintering of materials such as metal, resin, glass sand, also can be to be that the skeleton plated metal is made with soft porous material.The part of outer cover body below packed layer has uniform steam vent (3), and the shape of steam vent can be that circle, strip also can be other shapes, also can be split into a plurality of holes as required.The side of outer cover body is 110 °～150 ° with the angle of top flap, between it and the column plate existence of crack, the end is arranged also.
Among Fig. 2, A is the open-cellular form of orifice, and B is the open-cellular form of flange.The form of flange application at present is wider, because this structure can reduce the resistance of air-flow.Introduce the operation principle of this column plate below:
Liquid from the upper strata column plate after downspout flows down along this layer column plate lateral flow, gas from lower floor's column plate through air rising hole and rise pendular ring after enter jet cover.When gas speed is big and since pressure head on the column plate liquid and gas be injected in the gap generation negative pressure that rises pendular ring and jet cover, liquid through crack, the end after, be raised in this position, membrane, fragmentation, liquid carries out mass-and heat-transfer with the droplet form.The gas entrained drip carries out mass transfer once more by porous media or filler the time then, and the steam vent of last gas below outer cover body discharged.
When gas speed is slow, liquid can not be promoted, gas is walked around behind the jet cover in the packed layer between outer cover body and jet cover to contact in the bubbling mode with liquid and is carried out mass-and heat-transfer.Because the hole of porous media or filler is very little in the packed layer, gas is divided into minute bubbles, and the gas-liquid contacted specific surface area increases greatly, and its efficient is also considerably beyond the bubbling column plate.
Claims (2)
1, a kind of combined porous medium bubble cap plate is characterized in that: load onto in tower and have the horizontal column plate of air rising hole, the top of each air rising hole all rises pendular ring, and there is jet cover in its outside, and the top is not baffled, and crack, the end is arranged between jet cover and the column plate.Fill one section porous media or filler between outermost cover body and the jet cover, the part of outer cover body below packed layer has uniform steam vent, also has crack, the end to exist between cover body and the column plate.
2, combined porous medium bubble cap plate according to claim 1 is characterized in that: can make with the particles sintering of materials such as metal, resin, glass sand, also can be to be that the skeleton plated metal is made with soft porous material.
