Abstract
The utility model relates to a column tray with a rectangular combination valve, which belongs to the technical field of gas-liquid contact type mass transfer equipment in the oil refining, petrochemical and chemical industry. The column tray is formed by combining a column tray plate, a main valve and a sub-valve, the main valve is directly stamped by the column tray plate, the stamped main valve comprises a valve surface, a wide valve leg and a narrow valve leg, and the valve surface is isosceles trapezoid-shaped and is provided with a square hole in the middle; and the sub-valve adopts a floating valve and comprises a rectangular valve surface and two valve legs. When the gas flow of the column tray with the combination valve is small, the sub-valve is not opened, and the gas can pass only through the seam of the main valve, so that liquid leakage can not easily occur to the column tray; and when the gas flow is large, the sub-valve opens gradually, and the gas can pass through the seams of the main valve and the sub-valve simultaneously, so that mass transfer can occur to the gas phase and the liquid phase in the area on the valve surface of the main valve, and thus the area of the mass transfer phase boundary of the gas phase and the liquid phase in a column is effectively increased, the mass transfer resistance is reduced, and the efficiency of the column tray is improved.
Description
Technical field
The utility model relates to a kind of tower tray that is provided with the rectangle combination valve, belongs to gas-liquid contact mass transfer equipment technical field in oil refining, petrochemical industry and the chemical industry.
Background technology
At present, tower tray commonly used on oil refining, petrochemical industry and the chemical industry is float valve tray and Glitsch V-O tray, in use there is following shortcoming in these two kinds of tower trays: (1) though the float valve tray operating flexibility is big, its procedure complexity and waste material cause the increase of manufacturing cost.(2) solid valve tower tray processing is simple, and does not have the waste of material, but its operating flexibility is less.
Summary of the invention
The purpose of this utility model is a kind of tower tray that is provided with the rectangle combination valve of design, improve the structure of existing float valve tray and Glitsch V-O tray, on the valve face of standing valve, set up a little float valve, in the hope of when reducing manufacturing cost, increase the operating flexibility of tower tray, improve the gas-liquid contact of valve face top simultaneously, improve valve face top mass transfer utilization of space, thereby improve plate efficiency and mass-transfer efficiency.
The tower tray that is provided with rectangle shape combination valve that the utility model proposes is combined by tray deck, main-valve and sub-valve, the thickness l=1～5mm of tray deck.Main-valve directly is stamped to form by tray deck, main-valve after the punching press comprises valve face, wide valve leg and narrow valve leg, wherein, the valve face of main-valve is an isosceles trapezoid, and the centre has square hole, the upper base of isosceles trapezoid is width d1=18～25mm of narrow valve leg A3, going to the bottom of isosceles trapezoid is width d2=25～35mm of wide valve leg A2, the high h=45～80mm of isosceles trapezoid, the long a=25～35mm of square hole, wide b=15～25mm, the lift height h1=3 of main-valve～7mm.Sub-valve is a float trap, is made of the long f=25～35mm of rectangle valve face, wide g=15～25mm, the width w1=8～12mm of valve leg, the lift height h2=3 of sub-valve B～7mm rectangle valve face and two valve legs.
In the combinations thereof valve tower tray, sub-valve B is in the top of main-valve A, and the valve leg B2 of sub-valve B is stuck among the valve face hole A4 of main-valve A.

Among Fig. 1-Fig. 5, the 1st, tray deck, A are main-valves, and A1 is the main-valve valve face, and A2 is the wide valve leg of main-valve, and A3 is the narrow valve leg of main-valve, and A4 is a main-valve valve face square hole, and B is sub-valve, and B1 is sub-valve valve face, B2 is sub-valve valve leg.
The specific embodiment
The tower tray that is provided with the rectangle combination valve that the utility model proposes, its structure are combined the thickness l=1～5mm of tray deck 1 as shown in Figure 1 by tray deck 1, main-valve A and sub-valve B.Main-valve A directly is stamped to form by tray deck 1, main-valve A after the punching press comprises valve face A1, wide valve leg A2 and narrow valve leg A3, as shown in Figure 2, the valve face A1 of main-valve A is an isosceles trapezoid, and the centre has square hole A4, and the upper base of isosceles trapezoid is width d1=18～25mm of narrow valve leg A3, going to the bottom of isosceles trapezoid is width d2=25～35mm of wide valve leg A2, high h=45～the 80mm of isosceles trapezoid, the long a=25～35mm of square hole, wide b=15～25mm.As shown in Figure 3, the lift height h1=3 of main-valve A～7mm.As shown in Figure 4, sub-valve B is a float trap, is made up of rectangle valve face B1 and two valve leg B2, as shown in Figure 5, long f=25～35mm of rectangle valve face B1, wide g=15～25mm, width w1=8～12mm of valve leg B2, as shown in Figure 3, the lift height h2=3 of sub-valve B～7mm.
In the combinations thereof valve tower tray, sub-valve B is in the top of main-valve A, and the valve leg B2 of sub-valve B is stuck among the valve face hole A4 of main-valve A, as shown in Figure 3.
Introduce the operation principle of the tower tray that is provided with the rectangle combination valve that the utility model proposes in detail below in conjunction with accompanying drawing:
Combination valve tower tray of the present utility model, when tolerance hour, sub-valve B is not enough to open, this moment, gas only passed through from main-valve valve seam, because the more existing solid lift of a valve height of the lift height h1 of main-valve A is little, so hour be difficult for taking place a leakage situation in tolerance, when tolerance is big, sub-valve will be opened gradually with the increase of tolerance, and this moment, gas can pass through from main-valve valve seam and sub-valve valve seam simultaneously, make the gas-liquid two-phase can be at valve face A1 upper area generation mass transfer, this has just effectively increased the mass transfer phase contact area between gas-liquid two-phase in the tower, reduce resistance to mass tranfer, improve plate efficiency, simultaneously, main-valve adopts two valve legs of width, liquid on the tower tray is had guide effect, help reducing the gradient of liquid level of liquid layer on the tower tray, eliminate flow dead.
