Abstract
The utility model relates to a parabola oblique arc elliptical fixed flap valve and a slant hole tray of the same. The fixed flap valve is provided with a fixed flap body rising from the tray and the fixed flap body is in the shape of more than a half of an ellipse and rises upward to be open in the shape of the parabola oblique arc. The adopted elliptical fixed flap body has a large mass transfer ambitus than a rectangular fixed flap so as to increase contact chances of liquid and gas and improved mass transfer efficiency. Additionally, the elliptical fixed flap body rises upward to be open in the shape of the parabola oblique arc so as to perform downward buffer guide on a gas phase and effectively reduce entrainment. Meanwhile, a cutting hole of the slant hole is in the shape of more than a half of an ellipse so as to reduce stress of the tray and enhance the strength of the tray. The slant hole tray adopting the fixed flap valve has the advantages of improving the mass transfer efficiency and reducing the entrainment as well. Meanwhile, adjacent rows adopt an inverse staggering arrangement mode so as to further prolong contact time of the gas and the liquid and thus further improve the mass transfer efficiency.
Description
Technical field
The utility model relates to a kind of solid flap valve and a kind of slant-hole tray, the slant-hole tray that relates in particular to the oval solid flap valve of a kind of parabola askew arch and use this solid flap valve to make.
Background technology
In prior art, Chinese patent ZL94208565.5 has announced a kind of complex slant-hole tray, this complex slant-hole tray is provided with fixedly inclined hole, should be fixedly inclined hole be that the rectangle of perk is consolidated tongue from the column plate, their transversely arranged one-tenth is arranged more, and adjacent row's fixedly inclined hole reversed arrangement each other, makes that liquid is S-shaped on column plate to flow forward, can prolong gas-liquid contact time, improve mass-transfer efficiency.Though this slant-hole tray has been obtained the effect more superior than sieve tray, but some imperfection parts that exist, as: three sideline judges of the solid tongue of rectangle cut the hole and stayed the right angle that stress is concentrated on column plates, have reduced the intensity of column plate; The mass transfer periphery of unit perforated area is less than normal relatively, if solid tongue top can not mass transfer when perforate was big, secondly, the solid tongue body of rectangle is the straight plate of curved eaves under the front end band, though the curved eaves of this time can be avoided gas phase upwards to fling and increase entrainment, but cleanliness is poor, and mist entrainment can not more effectively be reduced, and these all have influence on mass-transfer efficiency.
The utility model content
The purpose of this utility model is in order to overcome the deficiency in the prior art, and oval solid flap valve of a kind of parabola askew arch and the slant-hole tray that uses solid flap valve to make are provided, in the hope of obtaining better effect at aspects such as improving mass-transfer efficiency and reduction entrainment.
For achieving the above object, the technical scheme of the solid flap valve of the utility model is as follows:
It has the solid tongue body of a perk from the column plate, and its improvements are: described solid tongue body is more than half ellipse, and upwarps unlatching with parabola askew arch shape.
Further improved technical scheme of flap valve is as follows admittedly for this:
Be provided with a little solid tongue body on described solid tongue body, this little solid tongue body is identical with the shape of described solid tongue body, and the unlatching that oppositely has a downwarp.
The technical scheme of the utility model slant-hole tray is as follows:
Has a column plate, mass-transfer zone at this column plate is provided with fixedly inclined hole of regularly arranged many rows, its improvements are: the fixedly reverse interleaved each other arrangement of adjacent row of inclined hole of described many rows, described fixedly inclined hole has the solid tongue body of a perk from the column plate, described solid tongue body is more than half ellipse, and upwarps unlatching with parabola askew arch shape.
The further improved technical scheme of this slant-hole tray is as follows:
Be provided with a little solid tongue body on described solid tongue body, this little solid tongue body is identical with the shape of described solid tongue body, and the unlatching that oppositely has a downwarp.
Find out that by technique scheme solid flap valve of the present utility model has adopted oval solid tongue body, the unit perforated area can improve 40% than the mass transfer periphery of the solid tongue of rectangle, has increased the gas-liquid touch opportunity, improves mass-transfer efficiency; Because oval solid tongue body upwarps with parabola askew arch shape, gas phase is played the downward guide effect of buffering again, can reduce entrainment effectively; In addition, oval solid the cut hole of tongue body on column plate is more than half ellipse, and the right angle of having avoided stress to concentrate has reduced column plate stress, has strengthened column plate intensity.The slant-hole tray that the utility model uses this solid flap valve to make, can improve the mass-transfer efficiency of slant-hole tray effectively and reduce entrainment, strengthen column plate intensity simultaneously, it has also adopted the Golden Triangle layout of adjacent row reverse interleaved arrangement each other, making liquid be heavy camber S shape on column plate flows, further prolonged gas-liquid contact time, mass-transfer efficiency is further improved.

The specific embodiment
Referring to Fig. 1,2, this admittedly flap valve have the solid tongue body 2 of a perk from the column plate 1, this solid tongue body 2 is more than half ellipse, and upwarps unlatching with parabola askew arch shape.
Referring to Fig. 3,4, in order to eliminate the mass transfer dead band on the solid tongue body 2, on described solid tongue body 2, be provided with a little solid tongue body 3, this little solid tongue body 3 is identical with the shape of described solid tongue body 2, and the unlatching that oppositely has a downwarp.
Use the solid flap valve in the foregoing description 1,2 can make a kind of slant-hole tray, its structure as shown in Figure 5, it has a column plate 1, mass-transfer zone at this column plate 1 is provided with fixedly inclined hole of regularly arranged many rows, should arrange the fixedly reverse interleaved each other arrangement of adjacent row of inclined hole more, described fixedly inclined hole has the solid tongue body 2 of a perk from the column plate 1, and described solid tongue body 2 is more than half elliptical shape, and upwarps unlatching with parabola askew arch shape; In order to eliminate the mass transfer dead band on the solid tongue body 2, a little solid tongue body 3 can be set on described solid tongue body 2, this little solid tongue body 3 is identical with the shape of described solid tongue body 2, and the unlatching that oppositely has a downwarp.
