Disk, linde sieve tray tower tray etc.）With cocurrent tower tray（Cocurrent sprays combined trapezoid spray tray）Distinguish only according to engineering process service condition
It is vertical to combine.
Background technology
In the gas-liquid mass transfer separation equipment of Chemical Engineering, board-like tower tray floor is obtained as a kind of conventional separation original paper
Be widely applied, wherein comparative maturity, widely used have bubble cap tray, sieve tray, solid valve tower tray, float valve tray, lead
The gas and liquid flowing tower tray of the forms such as combined trapezoid spray tray is sprayed to the cross-flow tower tray of the forms such as sieve tray, and cocurrent；Cross-flow tower
Disk is contacted, it is necessary to which larger downspout area and residence time ensure the gas phase carried secretly in liquid phase in descending liquid due to gas liquid cross-flow
Parsed in pipe；And cocurrent tower tray（Cocurrent sprays combined trapezoid spray tray）When liquid phase is flowed out by last layer downspout, due to
The problem of liquid is flowed to, it is easy to cause the uneven of in arcuate region sub-distribution at the beginning of liquid phase, then influence separating effect and
Flux.According to the complex form of cross-flow tower tray and cocurrent tower tray, then it can be fully solved upper during current tray design is selected
Problem is stated, operation flux and mass-transfer efficiency is improved.There is presently no combine cross-flow tower tray and cocurrent tower tray on one layer of tower tray
In the report being used together, particularly major diameter, high-throughout tower tray cases of engineering.
The content of the invention
The purpose of this utility model be directed to prior art defect there is provided a kind of simple in construction, safe and reliable
The combined tray being made up of cross-flow tower tray and cocurrent tower tray.
The combined tray being made up of cross-flow tower tray with cocurrent tower tray that the utility model is provided includes：The gentle liquid of cross-flow tower tray
Cocurrent tower tray；
Cross-flow tower tray is arranged close to seal pot side in liquid inlet, cross-flow tower tray is bubble cap tray, sieve tray, Gu Fata
Disk, float valve tray or linde sieve tray tower tray etc.；
Cocurrent tower tray is arranged close to downspout side in liquid outlet, cocurrent tower tray is cocurrent injection combined trapezoid spray tray；
The material characteristic and separation requirement separated according to chemical engineering, described cross-flow tower tray and cocurrent tower tray are in combination tower
It is evenly distributed in plate, cross-flow tower tray and cocurrent tower tray（Cocurrent sprays combined trapezoid spray tray）Both the number of openings ratios are 1：
0.1~10.Gas flows for vertical ascent in cross-flow tower tray effective district, and liquid phase is horizontal along tray deck towards downspout direction
To flowing, gas-liquid two-phase fluid contacts for cross-flow, and liquid layer gradient on the section of vertical liquid phase flow direction is essentially identical, distribution
Also it is uniform, then flow into cocurrent tower tray；
In gas and liquid flowing tower tray（Cocurrent sprays combined trapezoid spray tray）Gas and liquid are vertical cocurrent stream in effective district
Dynamic, gas-liquid mixed is contacted in mass transfer unit, after mass transfer separation, and gas phase continues to rise, and liquid phase is fallen, and flows into downspout；By
It is supernatant layer in the liquid layer fallen, the downspout area needed for the form tower tray is smaller, it is possible to make self-styled form（Described
Downspout is self-sealing downspout）, lift percent opening and operation flux.
Described cross-flow tower tray can use solid valve or float valve with guide function.
Described cocurrent tower tray outlet port suitably supplements perforate, improves gas phase flux and separative efficiency.
The characteristics of combined tray being made up of cross-flow tower tray and cocurrent tower tray that the utility model is provided has obvious：
1）Cross-flow tower tray and cocurrent tower tray are respectively arranged according to technological requirement on tray deck.Both percent openings require ratio
For 1：0.1 ~ 10, adjusted according to technological requirement；
2）Cross-flow tower tray uses solid valve or float valve with guide function, and arrangement, activation peace can be oriented in arcuate region
Determine area, promote liquid phase distribution；
3）In cross-flow tower tray effective district, gas liquid cross-flow is sufficiently mixed, and is mixed by the gas-liquid contact of cross-flow tower tray, tower tray
Liquid layer distribution than more uniform, in full tower section, liquid layer gradient is essentially identical, it is ensured that be flowed into cocurrent tower tray effective district
Interior liquid homogenizing and liquid layer are contour；
4）After being exchanged through cross-flow tower tray gas-liquid, liquid enters cocurrent tower tray（Cocurrent sprays combined trapezoid spray tray）, in cocurrent
Gas and liquid flowing in tower tray mass transfer unit, is reduced by power-assisted, improves mixed effect, and ensure that the liquid flowed into downspout is clear
Liquid layer；
5）It is supernatant layer due to flowing into downspout liquid, leads to without considering that gas phase parses required downspout in liquid phase
Amount, therefore the area needed for downspout is smaller, in some high flux occasions, can make the self-styled form of liquid phase, can improve full tower
Flux.

Embodiment
The utility model be explained in detail with reference to the accompanying drawings it is as follows, but for illustrative purposes only rather than limitation the utility model.
The combined tray being made up of cross-flow tower tray with cocurrent tower tray that the utility model is provided includes：Cross-flow tower tray 1 is gentle
Liquid cocurrent tower tray 4；
Liquid inlet close to the side of seal pot 3 arrange cross-flow tower tray, cross-flow tower tray 1 can be bubble cap tray, sieve tray,
Gu valve tower tray, float valve tray or linde sieve tray tower tray etc.；
In liquid outlet close to the side of downspout 2 arrangement cocurrent tower tray 4, cocurrent tower tray 4 is cocurrent injection combined trapezoid spray tray.
Example 1：
As shown in Fig. 3 a, Fig. 3 .b, liquid phase flows into the area of cross-flow tower tray 1 first in the position of seal pot 3 along tower tray effective district
Domain, enters supernatant layer after the region of cocurrent tower tray 4, gas-liquid mass transfer and flows into downspout 2 after mass transfer mixing；Wherein in cross-flow tower tray 1
Arcuate region is provided with the cross-flow tower tray with guide function so that liquid phase is distributed evenly, the liquid level on liquid is flowed vertically to
Gradient is essentially identical；The liquid phase of each mass transfer unit cocurrent tower tray 4 Nei is entered so as to ensure that evenly, rationally.
Traditional cross-flow tower tray in comparison diagram 1a, Fig. 1 b, liquid phase flows into downspout 2 in the position of seal pot 3 through cross-flow tower tray 1
Afterwards, due to also playing the substantial amounts of gas of entrainment, the larger downspout of form tower tray needs and residence time into downspout, so as to
Gas is parsed completely；
Traditional cocurrent tower tray in a of comparison diagram 2., 2. b, Fig. 2 c, liquid phase is coming out inflow simultaneously by the position of seal pot 3
Flow during tower tray 4, due to arcuate region and the relation of the relative position of last layer downspout, inevitably cause entry into bow
Liquid in row region is on the low side；
Under identical gas-liquid load, using the combined tray shown in Fig. 3 a, Fig. 3 .b, it is possible to reduce downspout width,
And then effective sector width is increased, increase the treating capacity of equipment；Because the gas-liquid of combined tray distributes more reasonable, the mass transfer of tower tray
Efficiency is expected to further raising.
Example 2：
As shown in Fig. 4 a, Fig. 4 .b, due to entering the liquid of downspout 2 after cross-flow tower tray 1 and the mass transfer of cocurrent tower tray 4
It is supernatant layer, in some industrial applications（Such as technological transformation）, can be using fluid-tight disk as from fluid-tight form, such shape
Formula, it is possible to which stoste closing disk region is changed into effective district, sets mass transfer unit, improves gas phase flux and separative efficiency.
Example 3：
As shown in Fig. 5 a, Fig. 5 b, in the arcuate region outlet side of cocurrent tower tray 4, setting unit cross-flow tower tray 1 improves perforate
Rate and the uniformity of gas-liquid distribution, promote liquid Rational flow.
