Abstract
A kind of wrong row's strip-shaped float valve tray, comprises column plate, described column plate has valve opening, and the arrangement mode between adjacent two valve openings is wrong row, and in T-shaped arrangement, be provided with rectangular valve in valve opening, described rectangular valve is provided with little standing valve.The utility model not only increases the disposal ability of gas-liquid, and the gas to go out from rectangular valve both sides is in " fourth " font, the gas that rectangular valve both sides go out does not liquidate, therefore the entrainment of column plate is less, little standing valve on rectangular valve also promotes the abundant contact of gas-liquid, enhance mass transfer effect, thus improve the efficiency of column plate.
Description
Technical field
The utility model relates to a kind of mass transfer resolution element in valve tower, is a kind of wrong row's strip-shaped float valve tray in particular.
Background technology
Valve plate has the advantage that operating flexibility is large, mist entrainment is little, leakage is few, disposal ability is large, mass-transfer efficiency is high, extensive use in chemical industry, petroleum industry, pharmaceuticals industry.
The maximum standard F1 type that remains Round float valve column plates is used in current industrial production, this float valve improves mass transfer condition to a certain extent, but because its structure problem still comes with some shortcomings: to all the winds blow out from valve opening gas out, make the liquid dispersion degree on column plate larger, on column plate, gradient of liquid level is comparatively large, reduces plate efficiency.Float valve constantly rotates under airflow function in addition, and cause valve pin and valve opening wearing and tearing, float valve easily blocks or comes off, and affects hydrodynamics and the mass-transfer performance of column plate, is even forced to shut-down (breakdown) mainteance.
Another kind of to use wider be strip-shaped float valve tray, and rectangular valve is rectangle, non rotating under airflow function, air-flow from the side opening that rectangular valve and valve opening are formed to become 90 with liquid flow path direction
oangle or be less than 90
othe direction ejection at angle, has good mass transfer effect.But this valve body also Shortcomings: if when gas load is larger, the rectangular valve quantity of needs is just many, and the distance between rectangular valve is just smaller, and the gas that rectangular valve both sides go out liquidates, and entrainment is comparatively large, reduces plate efficiency.
Utility model content
The purpose of this utility model is the deficiency overcoming above-mentioned valve plate, develops wrong row's strip-shaped float valve tray, can reduce entrainment, improve mass-transfer efficiency.
The utility model is achieved by the following technical programs:
A kind of wrong row's strip-shaped float valve tray, comprises column plate, described column plate has valve opening, and the arrangement mode between adjacent two valve openings is wrong row, in T-shaped arrangement, is provided with rectangular valve in valve opening.
Described rectangular valve is provided with little standing valve.
The side of described rectangular valve is provided with downward salient point.
The utility model has following advantage and good effect:
1. the adjacent two valve opening arrangement modes on column plate are wrong row, in " fourth " font.The gas gone out from rectangular valve both sides is in " fourth " font, and the gas that rectangular valve both sides go out does not liquidate, and therefore the entrainment of column plate is less, improves column plate mass-transfer efficiency.
2. rectangular valve is provided with little standing valve, little fixed valve hole gas is out identical or vertical with the liquid flow path direction on column plate, portion gas sprays from little fixed valve hole, form fine and closely woven bubble, form the gas-liquid contact of cladding, take full advantage of the mass transfer space on float valve top, make gas-liquid contact be continued strengthening, gas-liquid contact evenly, thus further mass transfer enhancement effect.
3. the side of rectangular valve is provided with downward salient point, make when rectangular valve drops to extreme lower position, salient point on rectangular valve contacts with the upper surface of column plate, ensure there is a minimum aperture between the side of rectangular valve and the upper surface of column plate, kill to prevent rectangular valve and column plate or glue dead, also can carry out gas-liquid mass transfer when tolerance is minimum.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of wrong row's strip-shaped float valve tray, comprises column plate 1, described column plate 1 has the valve opening 2 of rectangle, and the arrangement mode between adjacent two valve openings 2 is wrong row, in T-shaped arrangement, is provided with rectangular valve 3 in valve opening 2.After float valve is opened, rectangular valve 3 is parallel with column plate 1.
Described rectangular valve 3 is tabular, and this rectangular valve is provided with little standing valve 4.This little standing valve 4 directly can be gone out a gap and form on the flat board of rectangular valve 3.
The side of described rectangular valve is provided with downward salient point 5.
Claims (2)
1. wrong row's strip-shaped float valve tray, comprises column plate, it is characterized in that: described column plate (1) has valve opening (2), and the arrangement mode between adjacent two valve openings (2) is wrong row, in T-shaped arrangement, is provided with rectangular valve (3) in valve opening (2); Described rectangular valve (3) is provided with little standing valve (4), and this little standing valve (4) hole gas is out identical or vertical with the liquid flow path direction on column plate.
2. a kind of wrong row's strip-shaped float valve tray according to claim 1, is characterized in that: the side of described rectangular valve is provided with downward salient point (5).
