Abstract
The present invention relates to a high-effective large-flux fixed valve tower tray. It is formed from column plate, fixed valve and down-pipe. The fixed valve is formed by directly stamping the column plate self-body, and said fixed valve is composed of valve surface of fixed valve and valve leg of fixed valve, the valve surface is connected with column plate by means of valve leg of fixed valve, and the valve surface of the fixed valve has a downward bent folded edge. Said invented structure can raise treatment capacity of tower tray and its operation elasticity, at the same time the gas-liquid contact on the plate can be intensified so as to raise column plate mass transfer efficiency.
Description
Technical field
The present invention relates to a kind of efficient big flux Glitsch V-O tray, be mainly used in the various fractionating columns of industry, absorption tower, desorbers such as oil refining, chemical industry, petrochemical industry and light industry.
Technical background
Before the present invention made, the column plate of prior art had sieve tray, valve plate, frozen valve tray etc.Sieve tray has the advantage that pressure drop is low, be difficult for stifled, easy to process, cost saving, need not to overhaul.But sieve tray exists mist entrainment big, and leakage is serious, and operating flexibility is little, the shortcoming that mass-transfer efficiency is less.Valve plate has overcome some shortcomings of sieve tray, and it is big to have operating flexibility, and mist entrainment is little, and leakage is few, the advantage that mass-transfer efficiency is high.But the valve plate consumable quantity is big, and the manufacturing cost height easily stops up, and float valve blows off easily or blocks, the needs of incompatibility industrial at present " long, full, eugenic product cycle ".For advantage in conjunction with sieve tray and valve plate, overcome shortcoming each other, frozen valve tray occurred, as patent US5,360,583, US5,147,584, US5,975, the frozen valve tray that 504 grades are mentioned, the manufacturing expense of these frozen valve tray approaches sieve tray, and operating characteristics approaches valve plate and column plate intensity greater than sieve tray and valve plate.But, patent US5,360,583, US5,147,584, US5, the frozen valve tray that 975,504 grades are mentioned, its air-flow all is blown into liquid layer with horizontal direction from the standing valve side opening, with the air-flow that from adjacent standing valve side opening, the sprays phenomenon (as shown in Figure 8) that liquidates in the middle of two standing valves, two strands of air-flows that liquidate not only make the liquid on the column plate upwards splash, and increase liquid foam entrainment, reduce the disposal ability and the operating flexibility of column plate, and need consume big energy, the pressure drop that increases column plate.Simultaneously, air-flow is blown into liquid layer with horizontal direction, and liquid can be blown in the adjacent fixed valve side opening becomes leakage, increases leaking liquid amount, reduces the operating flexibility of column plate, reduces the mass-transfer efficiency of column plate.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easily manufactured, cheap efficient big flux Glitsch V-O tray, should overcome the shortcoming that has Glitsch V-O tray by efficient big flux Glitsch V-O tray, the direction of the gas that change blows out from the standing valve side opening, gas is blown on the column plate plate face under oblique from the standing valve side opening, reduce mist entrainment and leaking liquid amount, improve the disposal ability and the operating flexibility of column plate, strengthen gas-liquid contact mass transfer on the column plate simultaneously, improve the column plate mass-transfer efficiency.
Efficient big flux Glitsch V-O tray of the present invention, it is characterized in that, be somebody's turn to do efficient big flux Glitsch V-O tray by column plate 1, standing valve 2 and downspout 3 are formed, standing valve 2 is formed by the direct punching press of column plate 1 body, standing valve 2 is by standing valve valve face 4, liquid meeting valve leg 7 and liquid bearing valve leg 9 are formed, standing valve valve face 4 links to each other with column plate 1 with liquid bearing valve leg 9 by liquid meeting valve leg 7, standing valve valve face 4 has reclinate standing valve flanging 6, standing valve flanging 6 reclinate angle [alpha] are 10 °～60 °, and the standing valve flanging edge 12 of standing valve flanging 6 is apart from the plate face 3～10mm of column plate 1.The standing valve valve face 4 of efficient big flux Glitsch V-O tray is circle or rectangle or trapezoidal, when standing valve valve face 4 is circle, its diameter is 15～60mm, liquid meeting valve leg 7 and liquid bearing valve leg 9 are on the diameter line 10 of standing valve valve face 4, this diameter line 10 is orthogonal with the downspout 3 of tower tray, the width of liquid meeting valve leg 7 is more than or equal to the width of liquid bearing valve leg 9, when standing valve valve face 4 is a rectangle or when trapezoidal, standing valve valve face 4 long 20～80mm, standing valve valve face 4 wide 10～40mm, liquid meeting valve leg 7 and liquid bearing valve leg 9 are on the center line 5 of standing valve valve face 4, this center line 5 is orthogonal with the downspout 3 of tower tray, and the width of liquid meeting valve leg 7 is more than or equal to the width of liquid bearing valve leg 9.
Efficient big flux Glitsch V-O tray of the present invention, its advantage is:
1, avoids from adjacent two standing valve side openings the effluent air phenomenon that in the middle of two standing valves, liquidates, make that the gas that flows out the standing valve side opening is oblique to be blown on the column plate plate face down, minimizing mist entrainment, the disposal ability and the operating flexibility of raising column plate.
2, avoid from adjacent two standing valve side openings the effluent air phenomenon that liquidates, reduce energy consumption, reduce plate pressure drop.
3, avoiding from the standing valve side opening effluent air that liquid on the column plate is blown into adjacent fixed valve side opening becomes leakage, reduces leaking liquid amount, improves column plate mass-transfer efficiency and operating flexibility.
4, effluent air blows on the column plate plate face under oblique from the standing valve side opening, reduces bubble diameter, increases the gas-liquid contact area, strengthens gas-liquid contact mass transfer on the column plate, improves the column plate mass-transfer efficiency.
