Figure 15 is the valve block schematic diagram.(8) be valve block, (18) are the valve block perforate.
The height of double-flow injection float valve of the present invention (5) can height can be low, on column plate, can just be staggered.Open ratio of plate is 2～45%.
Double-flow injection float valve tray mechanism of mass transfer provided by the present invention is summarized as follows:
Figure 16 is a double-flow injection float valve tray mechanism of mass transfer schematic diagram.Shown in Figure 16 (a), under underload, valve block (8) does not float, whole column plate is equivalent to the macroporous plate that perforate is a valve block perforate size, from the perforate (18) of the gas that descends one deck column plate by valve block, enter the liquid level on the column plate, carry out the bubbling mass transfer in the liquid (19) of gas-liquid two-phase on column plate.
Shown in Figure 16 (b), along with the rising of gas speed, under moderate duty, valve block (8) floats gradually, is positioned at the middle part of passage I (12).Be divided into two strands from the following gas of one deck column plate by valve block this moment, and a part stopped by valve block, entered with the lower part by the valve block of passage I (12) and carry out the bubbling mass transfer on the column plate in the liquid layer; Another part is with the perforate (18) of higher gas speed by valve block, liquid on the column plate is sucked in the valve body by passage II (13), the gas-liquid two-phase high speed also flows turbulence and mixes, finish gas-liquid mass transfer, finishing gas-liquid two-phase by top passageway III (14) through guide plate (10) then separates, the liquid column plate that falls back, gas upwards enters the last layer column plate.
Continuation along with gas speed shown in Figure 16 (c) raises, and under high load capacity, valve block (8) floats fully, is positioned at the top of passage I (12).Be divided into two strands from the following gas of one deck column plate by valve block this moment, and a part stopped by valve block, entered with the lower part by the valve block of passage I (12) and carry out the bubbling mass transfer on the column plate in the liquid layer; Most of gas is with the perforate (18) of high gas speed by valve block, liquid on the column plate is sucked in the valve body by passage II (13), the gas-liquid two-phase high speed also flows turbulence and mixes, finish gas-liquid mass transfer, finishing gas-liquid two-phase by top passageway III (14) through guide plate (10) then separates, the liquid column plate that falls back, gas upwards enters the last layer column plate.
By above-mentioned mechanism of mass transfer as can be seen, the valve block of double-flow injection float valve can fluctuate along with the variation of gas-liquid load, regulates gas-liquid two-phase by different passages, to adapt to different operating conditions.Column plate is similar to macroporous plate under underload, and under high load capacity, gas is divided into two strands, respectively with the bubbling form with and flow the spray pattern mass transfer.With respect to common valve plate, it can adapt to load range widely.Its operation lower limit is suitable with common valve plate, i.e. be limited to 6～8 under the kinetic energy factor of underload lower disc perforate (18); The high load capacity lower disc floats to the top of passage I (12), and its maximum column plate perforate kinetic energy factor can reach 28, improves about 50% than common float valve (maximum column plate perforate kinetic energy factor is about 18).
By the column plate opening diameter is 50mm, and the valve block perforate is 35mm, is limited to 8 under the kinetic energy factor of valve block perforate (18), and maximum column plate perforate kinetic energy factor is 28 calculating, and the operating flexibility of this double-flow injection float valve is:
It is bigger more than 3 times than operating flexibility 18/8 ≈ 2.2 of common valve plate.Under identical open ratio of plate, be limited to 50% of common float valve under the operation of this double-flow injection float valve
, be limited in the operation 1.5 times (28/18 ≈ 1.5) of common float valve.
By aforementioned calculation contrast as can be seen, double-flow injection float valve tray provided by the invention has widely between the operating space than common valve plate, can adapt to operational load widely.
Double-flow injection float valve tray provided by the invention is compared with common valve plate, under the high gas speed, gas-liquid all belongs to the reinforcement mass transfer.As Figure 16 (b) (c) shown in, a part of gas is through the valve block baffling, entered by runner I (12) that liquid layer carries out gas-liquid mass transfer on the column plate, gas phase becomes first horizontal movement vertical lifting again by moving both vertically, prolonged gas-liquid contact time, has improved mass-transfer efficiency; Another part gas is risen by valve opening, mixes with the liquid at high speed that is sucked by passage II (13), and gas and liquid flowing is finished gas-liquid separation through guide plate then.This two parts gas has all carried out the reinforcement mass transfer with liquid, and this just improves the efficient of common valve plate bubbling mass transfer greatly.
Double-flow injection float valve tray provided by the invention is compared with common valve plate, valve body itself is fixed on the column plate, valve block is limited in the runner I (12) (space that is made of column plate, reinforcement, limiting plate) and fluctuates along with the variation of gas-liquid load, do not produce rotation (as Figure 13, shown in Figure 16), have simple in structure, life-span is long, and valve block is opened flexible characteristic.It is dumb that it has solved common float valve unlatching, owing to self fluctuating and rotating, with column plate spin friction, can produce the disadvantage that valve body comes off after the long-time operation.
Double-flow injection float valve tray provided by the invention is compared with common valve plate, because valve block is positioned at valve inner, can directly drop to because of the liquid of last layer column plate and cause valve block to open difficulty on the float valve.
Double-flow injection float valve tray provided by the invention is compared with common valve plate, because at valve inner gas-liquid two-phase and stream, therefore the permission gas speed of valve opening is very high, not only disposal ability can increase substantially, and gas and liquid flowing itself and very high valve opening gas speed also provide good anti-obstruction.
Outstanding substantial characteristics of the present invention and good effect can be embodied from following embodiment, but they are not that the present invention is imposed any restrictions.
