Further narrate the present invention below in conjunction with embodiment and accompanying drawing thereof:
The present invention is a kind of gas-liquid contact sub-assembly (referring to Fig. 1-5), comprise by two trapezoidal jet trays 12, two trapezoidal end plates 15 and a jet cover top board 11 of being attached thereto respectively and enclose the jet cover 2 that constitutes, jet cover 2 lower limbs are uniform to be connected with 2-4 leg 13, can be installed in jet cover 2 position of air rising hole 1 on the column plate 4 of knockout tower of mass transfer by leg 13, and make between the bottom surface of jet cover 2 and the column plate 4 and leave spacing; Be evenly equipped with spray-hole 14 on the described jet tray 12, it is characterized in that constituting horizontal profiles at described two jet trays 12, two trapezoidal end plates 15 and jet cover top board 11 is rectangle and vertical section is trapezoidal terraced rectangular jet cover 2; The base angle of described terraced rectangular jet plate 12 is 45～89 °; The base angle β of described terraced rectangle end plate 15 is 45～89 °; And between described jet cover top board 11 and two jet trays 12, have skylight 3; And the both sides abduction in jet tray 12 directions on the described jet cover top board 11 is symmetrically installed with deflector apron 7.
The described trapezoidal jet tray 12 of gas-liquid contact sub-assembly of the present invention is compared with traditional rectangular jet plate, the rectangular jet cover makes under the situation of same treatment amount, by changing the area of (dwindling) gas rising passway gradually, strengthened the rate of climb of gas, thereby make gas, liquid mixing in cover more abundant, improve mass-transfer efficiency; In addition, can also improve the disposal ability of knockout tower like this.And the design of deflector apron 7 can make from the skylight 3 liquid phases that eject as much as possible " interception " get off, reduce the gas-liquid back-mixing.
Gas-liquid contact sub-assembly of the present invention is further characterized in that the abduction part of described deflector apron 7 surpasses the jet cover lower edge in its vertical projecting line and bends, and constitutes the flap of γ angle downwards, and described angle γ is 90～180 ° (referring to Fig. 4).When angle γ is 90 °, mean deflector apron 7 bending parts vertically downward; And when angle γ is 180 °, mean not bending of deflector apron 7, be a flat board.The specific design of angle γ can be different and change to some extent according to the character (as density, viscosity etc.) of spent material.Generally speaking, angle γ preferable range is 100～160 °.
The further feature of gas-liquid of the present invention contact sub-assembly is, the whole height of gas-liquid contact sub-assembly is designed to two kinds, and its difference in height can generally be selected between 45～90mm according to the change of properties of actual condition and working media.Except that height, the shape and structure of two kinds of gas-liquid contact sub-assemblies is as broad as long.This design of differing heights gas-liquid contact sub-assembly is not the needs of itself, but in order to improve cooperation efficient, reduces the spray phenomenon, and it is installed in special design in the knockout tower of mass transfer.
The present invention has further designed the method to set up (referring to Fig. 1,2) of described gas-liquid contact sub-assembly in knockout tower of mass transfer, it is characterized in that earlier described gas-liquid contact sub-assembly being designed to two kinds of different height, and its difference in height is 45～90mm; Again on the spaced apart respectively column plate 4 that is mounted in the knockout tower of mass transfer at least one orientation in horizontal, vertical two orientations of the gas-liquid of described two kinds of differing heights contact sub-assembly, and the spray-hole of two adjacent gas-liquid contact sub-assemblies in height is on the different horizontal planes, be not on the same horizontal plane in other words, correspondence has air rising hole 1 below each described gas-liquid contact sub-assembly of column plate 4 then, and leaves fluid course between described gas-liquid contact sub-assembly end opening and column plate 4.Described here is designed to two kinds of different height to gas-liquid contact sub-assembly, mainly is meant the sustained height at the gas-liquid contact sub-assembly of prior art.Newly-designed gas-liquid contact sub-assembly can remain unchanged by a kind of height, another kind of highly reduction.This design can make the inventive method be used for the maintenance and the transformation of existing knockout tower of mass transfer simply and easily.But do not get rid of all designs newly of two kinds of differing heights of gas-liquid contact sub-assembly.This brand-new design is applicable to the whole new design of knockout tower of mass transfer.Described air rising hole 1 is the rectangle that contacts the bottom shape cooperation of sub-assembly with described gas-liquid.
