Problems solved by technology

At the same time, since the inclined valve legs at both ends of the bar-shaped solid valve produce a tensile effect when punching the solid valve, the opening height of the valve plate is restricted, resulting in a small side clearance area of ​​the solid valve, which affects the stability of the tray. Operational performance is adversely affected

Embodiment 1

[0050] When the liquid flow intensity on the valve orifice 2 (that is, the liquid flow rate per meter of weir length) L Figure 6 As shown, the liquid on the upper tray flows into the open area of ​​the valve orifice plate 2 through the liquid tray 1, and carries out gas-liquid contact with the gas phase flowing out from the first guide solid valve 4 and the second guide solid valve 5 on the tray, and then The gas rises and the liquid flows into the downcomer 3. The structural features of the first guiding solid valve 4 are as Figure 4a and 4b As shown, the valve plate 6 is directly punched out from the valve orifice plate 2, forming a valve hole 7 and a side gap 8 for gas circulation. The length of the valve hole 7 is 75mm, the width is 26mm, and the opening height of the valve plate 6 is 8-14mm. On the horizontal section of the valve plate 6, there is a small-sized fixed valve 10 of arch bridge type, and its valve hole 11 has a length of 24 mm and a width of 10 mm. At the ...

Embodiment 2

[0052] When the liquid flow intensity L=25~50m3 / m.h, the arrangement of the trays is as follows: Figure 7 shown. The structural features of the first guide valve 4 are as follows: Figure 4a and 4b As shown, the length of the valve hole 7 is 75mm, the width is 26mm, and the opening height of the valve plate 6 is 8-14mm. On the horizontal section of valve plate 6, be provided with the small solid valve 10 of arch bridge type, its valve hole 11 length is 24mm, and width is 10mm. The front end of the first guiding solid valve 4 is provided with a support plate 9 with a length of 16 mm and a thickness of 3 mm, which is only welded with the orifice plate 2 . Figure 7 The structural features of the second guiding valve 5 in Figure 5a and 5b As shown, the length of the valve hole 7 is 76mm, the width of the rear end of the valve hole is 30mm, the width of the front end is 22mm, and the opening height of the valve plate 6 is 8-14mm. The small solid valve 10 and the support pl...

Embodiment 3

[0054] When the liquid flow intensity L on the tray is >50m3 / m.h, the arrangement of the tray is as follows Figure 8 shown.

[0055] Its structural features of the first guiding solid valve 4 among the figure are as Figure 4a and 4b As shown, the length of the valve hole 7 is 75mm, the width is 26mm, and the opening height of the valve plate 6 is 8-14mm. The front end of the valve plate 7 is provided with a support plate 9 with a length of 16 mm and a thickness of 3 mm. The support plate 9 is only welded to the valve orifice plate 2 . Figure 8 The structural features of the second guiding solid valve 5 in Figure 5a and 5b As shown, the length of the valve hole 7 is 76mm, the rear end width is 30mm, the front end width is 22mm, and the opening height of the valve plate 6 is 8-14mm. The rest are basically the same as those of the above-mentioned first guiding valve 4 . Such as Figure 8 As shown, the second guide solid valve 5 is mainly arranged at the liquid inlet po...

Abstract

The invention relates to a novel guide solid valve tower plate. The novel guide solid valve tower plate comprises a valve pore plate, a liquid receiving tray and a down-flow pipe, wherein the liquid receiving tray is positioned at the upstream part; the down-flow pipe is positioned at the downstream part; the valve pore plate comprises a rectangular valve pore plate and arched valve pore plates; the rectangular valve pore plate is positioned in the middle of the valve pore plate; the arched valve pore plates are positioned on two sides of the rectangular valve pore plate along the liquid flow direction respectively; a guide solid valve is arranged on the surface of the valve pore plate and is positioned on the upper part of the valve pore plate. According to the novel guide solid valve tower plate with the structure, a supporting plate is arranged at the front end of the guide solid valve, so that the adverse impacts caused by an inclined front leg are eliminated, impelling force of a gas phase on a liquid phase is increased, and a solid valve can be conveniently machined; due to the structural style of the guide solid valve and a proper side clearance area, the pressure drop of the tower plate is reduced, and the processing capacity is improved; the back-mixing of liquid on the tower plate is low, and liquid level gradient and liquid stagnation areas can be eliminated under different liquid load conditions, so that the novel guide solid valve tower plate is high in efficiency.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to the technical field of gas-liquid mass transfer, and specifically refers to a novel guiding and valve-fixed tray. Background technique [0002] Tray tower is an important gas-liquid mass transfer equipment, which is widely used in chemical industry, oil refining and petrochemical industry. There are many types of trays, commonly used in industry are sieve trays, solid tongue trays, solid valve trays and float valve trays. The sieve tray has a simple structure and is easy to process and manufacture, but the operation flexibility is small. There are floating parts on the floating valve tray, which can automatically adjust the gas phase channel to a certain extent, and has greater operating flexibility. Among the valve-type trays, the combined guide valve tray (Chinese patent 96229716.X) can better eliminate liquid level gradient and liquid stagnation zone, and has good...
