Abstract
The utility model relates to a composite tower composed of a tower body (1), sieve plates (2), and a corrugated filler (3), wherein, the corrugated filler (3) is arranged at the position which is appressed with the lower parts of the sieve plates (2), so the dead space of mass transfer between the sieve plates (2) is fully used. The utility model has the advantages of large area of gas-liquid mass transfer, large gas-liquid fluid flux, uniform liquid separating distribution, good mass transfer effect, high plate efficiency, etc., and can be used in situations such as rectification, gas-liquid absorption, gas-liquid two-phase direct heat transfer, etc. The utility model can enhance the yield and the quality of products for towers with the same condition and under the same operating condition.
Description
The utility model belongs to tower, and especially combination tower is applicable to occasions such as rectifying, GAS ABSORPTION, gas-liquid two-phase direct heat transfer.
Before the utility model is made, be applicable to rectifying, GAS ABSORPTION, occasions such as gas-liquid two-phase direct heat transfer, the most close prior art is by tower body both at home and abroad, sieve plate, downspout, the sieve-plate tower that wire mesh packing is formed, sieve plate is connected with downspout, sieve plate and downspout are set in the tower body, wire mesh packing is set on the sieve plate, the sieve plate spacing of general such tower is 450～600 millimeters, 4～9 millimeters in the aperture of sieve aperture on the sieve plate, sieve-plate aperture ratio 5～8%, 6～25 millimeters of corrugated wire gauze packing height, liquid flows down cross-current through this sieve plate from the downspout of lastblock sieve plate, and the downspout from this sieve plate opposite side flows down cross-current through next piece sieve plate then, and the sieve aperture that gas passes sieve plate from bottom to top flows, thereby on sieve plate, form froth bed, gas-liquid is mass transfer in froth bed, on the sieve plate wire mesh packing is set after, its operation principle is that the filler on the sieve plate can improve the bubbling situation, make the bubble of froth bed disperse forr a short time, increased the gas-liquid contact area.Thereby improved mass-transfer efficiency, veneer efficient can reach 80～100%, compares with common sieve-plate tower, veneer efficient can improve about 40～50%, and such tower structure is fairly simple, but the gas-liquid flux is big inadequately, do not utilize the mass transfer dead space between sieve plate, influenced the increase rate of plate efficiency.
The purpose of this utility model is the shortcoming that overcomes prior art, provide a kind of simple in structure, make full use of that mass transfer dead space between sieve plate, gas-liquid flux are big, uniform gas-liquid distribution, combination tower that plate efficiency is high.
Combination tower includes tower body 1, sieve plate 2, mainly is made up of corrugated plate packing 3, sieve plate 2 spacings that are arranged in the tower body 1 are 200～500 millimeters, the aperture of sieve aperture is 4～15 millimeters on the sieve plate 2, and the percent opening of sieve plate 2 is 15～30%, corrugated plate packing 3 is set being close to sieve plate 2 bottoms.The height of corrugated plate packing 3 is 50～200 millimeters.
Operation principle of the present utility model is: each layer at this tower constitutes composite plate by sieve plate 2 and corrugated plate packing 3, sieve plate 2 directly is placed on the corrugated plate packing 3, sieve plate 2 is with the fixing of corrugated plate packing 3 and support the structure that can adopt general tower, its operation principle is the gas-liquid counter current contact, liquid from top to bottom flows through sieve plate 2 and corrugated plate packing 3, gas from bottom to top flows through corrugated plate packing 3 and sieve plate 2, it on the sieve plate 2 bubbling, be that liquid phase is a continuous phase, gas phase is a decentralized photo, on the contrary in corrugated plate packing 3, gas phase is a continuous phase, liquid phase is a decentralized photo, sieve plate 2 bottoms are provided with corrugated plate packing 3, utilized mass transfer idle space between the sieve plate 2, in identical space, increased gas-liquid mass transfer area, make that simultaneously the liquid foam entrainment amount significantly reduces almost nil between the sieve plate 2, the distribution of gas of the corrugated plate packing 3 feasible sieve plates 2 of from bottom to top flowing through that sieve plate is provided with for 2 times is even, thereby make that froth bed is even on the sieve plate 2, sieve plate 2 on the corrugated plate packing 3 has played the effect of liquid distribution trough, liquid distribution in the feasible corrugated plate packing 3 of from top to bottom flowing through is even, thereby mass-transfer efficiency is further improved.
The utility model compared with prior art, have simple in structure, made full use of mass transfer idle space between the sieve plate 2, gas-liquid mass transfer area is big, and the gas-liquid flux is big, uniform gas-liquid distribution, mass transfer effect is good, the plate efficiency advantages of higher, veneer efficient can reach 100～130%, compares with common sieve-plate tower, about veneer efficient can double, gas-liquid flux ratio prior art improves 20～30%, and tower and same operation condition for similarity condition can improve separation degree greatly, obtain high quality of products, increase production capacity, improved the output and the quality of product, reaching under the identical separation degree, can reduce reflux ratio, thereby reach purpose of energy saving, socio-economic efficiency is remarkable, has broad application prospects and promotional value.

Wherein 1---tower body, 2---sieve plate, 3---corrugated plate packing.
Fig. 1, Fig. 2 is embodiment of the utility model, as Fig. 1, shown in Figure 2, with the tower internal diameter is that 100 millimeters combination tower rectifying separating alcohol-water system is an example, tower body 1 height is 2.6 meters, totally 11 on sieve plate 2 is set in the tower body 1, sieve plate 2 spacings are 230 millimeters, the aperture of sieve aperture is 5 millimeters on the sieve plate 2, the percent opening of sieve plate 2 is 30%, sieve plate 2 bottoms are provided with corrugated plate packing 3 and highly are 50 millimeters, tower body 1 bottom at this combination tower can add the tower still, add condenser device at tower body 1 top, ethanol-water solution in tower body 1 bottom column still, heater via heating generation steam (ethanol and steam) is flow through corrugated plate packing 3 and sieve plate 2 from descending, enter the condenser at tower body 1 top one by one through the composite plate that is made of corrugated plate packing 3 and sieve plate 2, the liquid in condenser under the condensation (second alcohol and water) flow through from top to down sieve plate 2 and corrugated plate packing 3 are one by one through the composite plate that is made of sieve plate 2 and the corrugated plate packing 3 tower still to tower body 1 bottom.Like this through halfhour rectifying, alcohol-water system feed liquid is 20% to be separated into the alcohol that tower body 1 top contains 94.5% ethanol from initial concentration of alcohol, tower body 1 bottom column still obtains containing the water of 0.1% ethanol, veneer efficient can reach about 130%, compare with common sieve-plate tower, veneer efficient can double, and gas-liquid flux ratio prior art improves 20%, increase production capacity, improved the output and the quality of product greatly.
