According to the novel efficient column tray screening plate, a column tray comprises a column plate, wherein square holes are distributed in the column plate; screening plates are distributed corresponding to the square holes in the column plate on the column plate; the two sides of a main body of a screening plate structure are arc-shaped, and the other two sides of the main body are used for vertically sealing the arc-shaped sides; a plurality of rows of circular holes are distributed in the arc-shaped sides; the novel efficient column tray screening plate comprises a cover plate and a separation plate; the cover plate is circular-arc-shaped and the separation plate is a V-shaped strip plate. A gap with a certain distance is formed between the bottom of each of the two arc-shaped sides of the main body and the column plate; thin sheets connected with the bottoms of the two sides of a vertical plane of the screening plate are provided with bolt holes so as to be conveniently and fixedly connected with the column plate.
Description
Technical field
The utility model relates to a kind of petrochemical equipment, is specifically related to a kind of dry gas desulfurizing tower tower tray sieve plate.
Background technology
In petrochemical industry dry gas desulfurizing tower sweetening process, dry gas enters in tower from tower bottom, rises and carries out mass transfer through tower tray and the sweetening liq entering from tower top, thereby arrive the object of desulfurization.To be gas carry through column plate the liquid flowing in sieve plate upwards forms air-flow at a high speed in the concrete effect of tower tray, liquid carried out to discretization, the gas-liquid contact namely carrying out under high velocity jet state.The liquid dispersion ejecting from sieve plate becomes a large amount of droplets, and for gas-liquid contact provides very large contact area, mass-transfer efficiency improves greatly.But current existing tower tray technology can not reach the desulfurized effect of wanting sometimes, to propose a kind of desulfurized effect higher for patent of the present invention for this reason, the better new and effective tower tray sieve plate of mass transfer effect.
Summary of the invention
In order to improve desulfurized effect, the utility model proposes a kind of new and effective tower tray sieve plate, concrete technical scheme is: a kind of high-efficient tower plate sieve plate, comprises two arcs, the two ends of arc are vertically sealed by sieve plate side plate, top at sieve plate is provided with cover plate, is provided with dividing plate at the bosom of sieve plate, and the welded top of dividing plate on the cover board, the bottom of sieve plate side plate is provided with leg, on leg, be provided with bolt hole, by bolt hole, sieve plate be fixed on column plate.
The utility model, because sieve plate both sides are arc, sieve plate bottom two arc distance are wider upwards to close up gradually and then relaxes, be horn-like, when dry gas is carrying the liquid at high speed entering from gap, sieve plate bottom while upwards spraying from bottom, form Venturi effect, increase a speed, thereby can be dispersed into more substantial little liquid to the better broken atomization of liquid, greatly for gas-liquid increases contact area, increase greatly mass-transfer efficiency, made two kinds of substance reactions more abundant, thereby strengthened desulfurized effect.Both sides are vertically sealed curved side in addition, many row's circular ports that distributing on arcwall face, and between every round, the distribution in hole is staggered, and when air-flow sprays from hole like this, can better disperse, and increases material contact area, has improved desulfuration efficiency.
Its cover plate is arc-shaped slot, dividing plate is V-arrangement batten, play a part water conservancy diversion, in the time that air-flow enters at a high speed from sieve plate bottom, rise to top and form shunting along dividing plate both sides, reduced air-flow bounce-back simultaneously, mass transfer velocity and mass-transfer efficiency are increased, air-flow by dividing plate along curved cover plate circulate rapidly refunds column plate produce high turbulences, also mass-transfer efficiency and speed have been increased, main body arc both sides distance from bottom column plate has the gap of certain distance, so that liquid flows into, the thin slice that sieve plate vertical plane two side bottoms are attached thereto carries bolt hole, so that be fixed and be connected with column plate.In order to prevent that tower tray is by material corrosion, the material of whole tower tray is stainless steel.
The high-efficient tower plate that the utility model proposes in sum can improve mass-transfer efficiency greatly, thereby increases desulfurized effect, and flexible for installation, simple in structure, has higher stability.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Fig. 1～4, a kind of high-efficient tower plate sieve plate, around forming by two arcs 2 and sieve plate side plate 6 not with holes, be provided with cover plate 1 at the top of sieve plate, be provided with dividing plate 4 at the bosom of sieve plate, the welded top of dividing plate is on cover plate 1, the bottom of sieve plate side plate 6 is provided with leg 5, on leg 5, be provided with bolt hole 3, by bolt hole 3, sieve plate be fixed on column plate.Sieve-plate structure main body both sides are arc therein, sieve plate bottom two arc distance are wider upwards to close up gradually and then relaxes, form Venturi effect, making air-flow increase increases a speed, thereby can be dispersed into more substantial little liquid to the better broken atomization of liquid, greatly for gas-liquid increases contact area, sieve plate side plate 6 vertically seals curved side in addition, many row's circular ports are distributing on arcwall face, between every round, the distribution in hole is staggered, when air-flow sprays from hole like this, can better disperse enlarge active surface.
As shown in Figure 3, cover plate 1 is circular arc, dividing plate 4 is V stripe board, play a part water conservancy diversion, in the time that air-flow enters at a high speed from sieve plate bottom, rise to top and form shunting along dividing plate both sides, reduced air-flow bounce-back simultaneously, mass transfer velocity and mass-transfer efficiency are increased, air-flow by dividing plate along curved cover plate circulate rapidly refunds column plate produce high turbulences, also mass-transfer efficiency and speed have been increased, main body arc both sides distance from bottom column plate has the gap of certain distance, so that liquid flows into, the thin slice that sieve plate vertical plane two side bottoms are attached thereto carries bolt hole 3, so that be fixed and be connected with column plate.In order to prevent that tower tray is by material corrosion, the material of whole tower tray is stainless steel, and sieve plate is fixed and is connected with bolt with tower tray, and cover plate two ends are together with sieve plate vertical plane welded top in addition, and dividing plate and cover plate are welded and fixed.
