Problems solved by technology

In the prior art, they are generally independent systems, not combined with each other
In addition, whether it is a vertical sieve tray or a bubble-cap tray, they are not ideal in structure. They all need to open holes in the tray, and then install caps or riser structures on the openings. This structure is relatively expensive. , if the opening rate is high, it may also reduce the mechanical strength of the tray, and at the same time, it is not convenient to disassemble

Embodiment 1

[0033] see figure 1 , 2, the three-dimensional sieve plate has a plurality of trapezoidal channel steels 1, which are arranged in parallel along the cross section of the tower, and half trapezoidal angle steels 1a, 1b are arranged between the two sides of the plurality of trapezoidal channel steels 1 and the tower wall, and the trapezoidal channel steels 1 and half-trapezoidal angle steel 1a, 1b have recesses facing upwards; the upper ends of the inclined plates on both sides of the trapezoidal channel steel are docked with the left and right inclined plates of the adjacent trapezoidal channel steel 1', 1", and are connected together by fastening bolts 2 The side slant plates of the semi-trapezoidal angle steels 1a, 1b and the upper ends of the side slant plates of the adjacent trapezoidal angle steels 1', 1" are also butted and fixed in the same way, so that between each trapezoidal channel steel and between the semi-trapezoidal angle steel Between the adjacent trapezoidal ...

Embodiment 2

[0038] see Figure 5 , 6 , the three-dimensional sieve plate has a plurality of channel steels 15, which are arranged in parallel at equal intervals along the cross section of the tower, and half channel angle steels 15a, 15b are arranged at intervals between the two sides of the multiple channel steels and the tower wall, and the channel steels and the half channel steels The concave portion of the channel angle steel is upward; between two adjacent channel steels 15 and between the half-channel angle steel and its adjacent channel steels, a straight-wall ascending air passage 16 is formed, and the two ends of the ascending air passage are provided with sealing plates 17 to make the ascending Both ends of the air passage are closed; a blister 18 is reversed at the upper end of the ascending air passage 16, and the lower part of the blister 18 is provided with the same tooth-shaped or grid-shaped tooth gap as in Example 1, or is provided with evenly distributed bubbling holes;...

Embodiment 3

[0041] Referring to Figures 9, 10, and 11, on the basis of the structure of the bubble-cap three-dimensional sieve plate in Embodiment 1 or 2, they can be changed into a through-flow bubble-cap three-dimensional sieve plate, that is, the above-mentioned trapezoidal channel steel 1 and half trapezoidal angle steel. The lower end of the plate or the channel steel 15 and the uniformly distributed liquid phase holes at the lower end of the side vertical plate of the half-channel angle steel are changed into film-drawing holes 1-11, 15-11 and liquid phase distribution holes 1-12, 15-12, which are arranged in a staggered transverse direction, And on distribution hole 1-12,15-12, be buckled with diversion groove 19,19 ', simultaneously, on the channel bottom plate of trapezoidal channel steel 1 and half trapezoidal angle steel or channel steel 15 and half channel angle steel, also arrange evenly distributed Liquid phase distribution holes 1-13, 15-13. see Figure 12 , 13 , the thro...

Abstract

The invention relates to a foam mask solid screen plate, wherein it has several trapezia groove steels on the support of tower chassis, while they are parallel arranged along the section of tower and their concaves are upward; the upper end of side incline plate of each groove steel are connected, to form a triangle gas lifting tube; the upper and lower parts of groove steel has gas liquid hole and liquid hole; the top of gas lifting tube has foam mask; the lower part of mask has foaming slit. The invention can transmit foam vertically and lift the foam, to prolong the gas-liquid contact time and process the transmissions of vertical screen plate and foam mask tower chassis synchronously.

Description

technical field [0001] The invention relates to a vertical sieve plate and a bubble-cap tray, in particular to a bubble-cap three-dimensional sieve plate integrating the mass transfer performance of the vertical sieve plate and the bubble-cap tray. Background technique [0002] The structure of the existing vertical sieve plate is to open holes on the tray 22, such as Figure 15 As shown, a cap 23 fastened on the perforation is arranged at each hole position, and a gap 24 is left at the fastening position (that is, between the cap and the tray), and a gas-liquid hole 25 is provided on the top of the cap. . The working principle of the tray is: when the liquid flows through each cap, the liquid phase flows into the cap through the gap; the gas from the bottom of the tray rises from the opening of the tray to the cap, and the rising gas will enter the cap. The liquid phase inside the cap pulls the film and atomizes along the inner wall of the cap. The gas-liquid two-phase int...
