Column plate as one of rectifying column equipment is most widely used, and accounts for more than 90% of tower.At present, the novel column plate of having developed has reached tens kinds, and conclusion is got up, and column plate can be divided into two classes: i.e. fixedly column plate and valve plate.Fixedly column plate comprises sieve aperture tower tray and MVG tower tray, and the sieve aperture tower tray is to open a plurality of holes 12 on a block plate 11 as shown in Figure 1; The MVG tower tray is a plurality of projections 22 that directly strike out certain altitude and shape on a block plate 21 as shown in Figure 2.Valve plate is to punch on steel plate, and above the hole float valve is installed, and the kind of float valve can be a rectangular valve, as shown in Figure 3, or circular float valve, as shown in Figure 4, as the F1 valve plate, Koch-glitsch T type valve plate.This class column plate may show comparatively superior performance in some aspects, but in some deficiency that has also reflected in varying degrees on structure and the performance.
Though the existing fixed column plate has advantage of simple structure, operating flexibility is little aborning, leaks greatly, and mass-transfer efficiency is low; Though valve plate has had bigger improvement on operating flexibility, in long period of operation, valve body easily rotation comes off; Gradient of liquid level on the column plate is big, makes gas skewness on liquid flow direction, easily produces the liquid excessive leakage at the column plate arrival end, produces easily at the port of export that liquid is excessive to be carried secretly, and column plate arch area back-mixing is serious, has had a strong impact on plate efficiency.
Improve the liquid and gas disposal ability on the column plate, improve mass-transfer efficiency and operating flexibility, the most important thing is to reduce entrainment, leakage and plate pressure drop, reduce the liquid dispersion degree on the column plate.This just requires gas-liquid two-phase as much as possible evenly disperseing, and makes the contact of vapour-liquid two-phase multiple spot, reduces the back-mixing probability of liquid.
Summary of the invention
The purpose of this utility model is comprehensively the fixedly advantage of column plate and valve plate, overcomes the deficiency, and both are organically combined, and the solid valve and the mutually integrated self adaptation valve plate of float valve of a kind of new and effective, high operating flexibility and high mechanical properties is provided.
Newly-designed a kind of solid valve of this practicality and the mutually integrated self adaptation valve plate of float valve, comprise a metal foil, it is characterized in that, the solid valve of stamping forming a plurality of rectangle or trapezoidal projection is arranged on this metal foil, the surface of the solid valve of this each projection has square type or circular port, and corresponding rectangle or circular miniature float valve are installed in this perforate.
The height of the solid valve of described each projection can be 2-5mm, and base length can be 50-70mm, and width can be 30-40mm.
The surface of this each solid valve and float valve can also offer pilot hole according to the different of application scenario, also can not perforate.
The characteristics of the self adaptation valve plate that the solid valve of the utility model design and float valve are mutually integrated are: air-flow through slit that the steel plate upper punch rises and the perforate on bulge-structure surface spray into liquid layer, form many minute bubbles, changed the single situation that solid valve contacts with gas-liquid on the same level of valve plate, formed the multi-level three-dimensional way of contact, thereby more bubble point is arranged, thereby improve mass-transfer efficiency.Conclusion is got up, and the utlity model has following advantage:
(1) the utility model adopts the unique texture that solid valve and float valve combine, and has made full use of the mass transfer space of column plate and float valve top, makes gas dispersion finer and closely woven evenly, and the gas-liquid contact is more abundant.The part air-flow has reduced the gas speed of valve periphery ejection through solid valve opening ejection simultaneously, and the air-flow that has also reduced between valve simultaneously liquidates, thereby has reduced entrainment, the corresponding gas treatment amount that improved.
(2) structure of moving admittedly combination can be according to the different control operation situations of regulating automatically of gas treatment amount, and in treating capacity hour, float valve cuts out, and gas is from solid valve opening ejection, and this moment, column plate was solid valve column plate, satisfied the needs of production lower bound; Along with the increase for the treatment of capacity, the column plate form changes to the New Valve Trays of moving admittedly combination gradually, and at this moment, the float valve above the solid valve is opened gradually, satisfying big flux requirement, thereby increases substantially the operating flexibility of tower.
(3) solid valve portion of the present utility model can be trapezoidal or two kinds of structures of rectangle.Difference according to handling system two-phase load can adopt different solid valve arrangements, to reduce the gradient of liquid level of column plate top, reduces the entrainment and the leakage of column plate part; Simultaneously, reduce the stagnant area that the column plate top exists, improve the uniformity of liquid distribution.
(4) float valve above the solid valve can be round valve and bar valve.Its float valve can not be rotated.This has not only overcome the local leakage problem that float valve that the rotation of F1 float valve brings comes off and causes, simultaneously, the mode of gas-liquid contact is also optimized, traditional solid valve and the single same plane contact problem of float valve have been changed, attaching space is extended to three-dimensional contact, promote mass transfer area, strengthened mass transfer effect.
(5) move the self adaptation valve plate of combination admittedly because of perforate on different aspects (Gu perforate of slit of valve and solid valve surface), make the easy coking system of thickness be difficult to be deposited in valve body surface, simultaneously the gas that comes out from the slit of the solid valve of projection have one with the horizontal component of liquid flow path direction, quicken thickness easy coking material and tied up to movement velocity on the column plate, reduce the stop time, thereby reduced the probability of coking greatly.
(6) mechanical strength that the rectangle of projection or trapezium structure have been strengthened column plate on steel plate.
The utility model is compared with conventional F1 valve plate, and entrainment and leakage reduce about 30%-40%, and treating capacity can improve more than 30%, has improved the operating flexibility of column plate greatly; Plate pressure drop reduces more than the 30%-40%; Actual plate efficient can improve about 15-20%.

The specific embodiment
Below in conjunction with accompanying drawing, introduce content of the present utility model in detail.
The part of the self adaptation valve plate embodiment that solid valve of the present utility model and float valve are mutually integrated (combination of solid valve and float valve) structure as shown in Figure 5, among the figure, the 1st, steel plate, the 2nd, the solid valve of projection, the 3rd, solid the valve surface perforate, the 4th, float valve, the 5th, solid the valve slit.Float valve 4 is installed in solid valve surface perforate 3 places, and float valve 4 can consolidated the lifting vertically freely of valve surface tapping, and can not move horizontally.Solid valve 2 height H of projection (promptly the valve valve stitches height admittedly) are 2～5mm, and length L is 50-70mm, and width B is 30-40mm; Gu the size of valve body surface perforate is decided according to side's mounted thereto float valve size, select rectangular valve 4 for use as the float valve of present embodiment, then offer bar hole 3, length is generally 30～40mm, width is generally 20～25mm, also can select circular float valve for use, its bore size is generally 20mm～ 25mm.
The combining structure of a plurality of above-mentioned solid valves and float valve is distributed in same monoblock steel and pulls, and then becomes self adaptation valve plate of the present utility model.
The utility model can be regulated automatically according to the treating capacity of production operation when operation.When the gas treatment amount hour, gas is not enough to the float valve of the solid valve of jack-up top, therefore float valve is in closed condition fully, this moment, the utility model was solid valve state, thereby gas is from the two side valve seams ejection of solid valve, highly less because of the design's valve seam, thereby the leakage rate of column plate is significantly less than conventional sieve tray and solid valve column plate, therefore improved the operation lower limit of device greatly; When the gas treatment amount increases gradually, gas is the float valve of the solid valve of jack-up top gradually, this moment, float valve was along with the increase of tolerance slowly opens, this moment, mode of operation thought that the utility model changes, gas sprays simultaneously with consolidating valve valve seam and float valve valve seam place simultaneously, in same gas and liquid handling condition, because of the shunting action of solid valve valve seam, via hole speed reduces, thereby greatly reduces the generation of entrainment.Because the float valve that the utility model is selected for use is less, its size and weight are about half of conventional float valve, thereby greatly reduce plate pressure drop simultaneously; Gas from the ejection of solid valve valve seam has a horizontal component along liquid flow direction simultaneously, can promote the liquid flow in the stagnant area on the column plate, be that liquid flow on the column plate is even, when having avoided excessive leakage and entrainment, also improved mass-transfer efficiency; Admittedly valve valve seam is positioned at different planes with float valve valve seam in addition, made full use of the space and the mass transfer space that reaches the float valve top of column plate, strengthened the gas-liquid contact point, made gas dispersion finer and closely woven evenly, the gas-liquid contact is more abundant, thereby also can improve its mass-transfer efficiency greatly.
