Its principle are as follows: gas passes through the air rising hole (3) on plate and rises, because rising gas passages shrink, speed is got higher, and gas becomes
For the jet stream of high-speed motion.The gas that passes through of high speed forms low pressure in CTST calotte, is kept on file in advance gap drop by jet tray lower end
The sucking of the liquid on plate will be collected, and be sufficiently mixed contact therewith, carry out interphase mass transfer.
Liquid from upper layer packing section is enriched on catch tray (1), forms certain altitude liquid layer；Pass through jet tray lower end
Keep on file gap in advance, liquid is drawn into mixing in CTST calotte (2) riser by the gas of high-speed motion, and further promotion, membrane,
Broken, gas and liquid two phases come into full contact with, and enhance mass transport process.
Liquid is by entering next packing section by catheter (5) after liquid distributing hole (4) even cloth.
Traditional distributor because of blocking that riser flows liquid and liquid flow irregularity in the radial direction itself,
So that the liquid on catch tray the problems such as there are concentration distribution differences, liquid level drop.CTST calotte passes through setting bottom gap, benefit
The three-dimensional process intensification drawn liquid into gas, promoted, mix, sprayed liquid flowing, to solve above-mentioned tradition
Distributor there are the problem of.
Gas passes through the air rising hole (3) on plate and rises, and the gas passed through at a high speed contacts in CTST calotte with liquid.It comes from
The liquid of upper layer packing section is enriched on catch tray (1), forms certain altitude liquid layer；By gap of keeping on file in advance, pass through the channel liquid
Body is carried to mixing in CTST calotte (2) riser by the gas of high-speed motion, and further promotion, membrane, broken, air-liquid
Two-phase comes into full contact with, and enhances mass transport process.
Liquid is by entering next packing section by catheter (5) after liquid distributing hole (4) even cloth.
Having built a set of diameter is 580mm organic glass tower test macro, is carried out with air-water system to the distributor
Distribution performance test.
Distributor Performance Test System mainly includes several parts such as water system, ventilating system, metering section, distributor.
Blower is opened, the differential manometer of regulating butterfly valve aperture, observation connection Pitot tube is sized depending on counting to；It opens after a period of stabilisation
Centrifugal pump will be promoted to diameter 580mm freezing mask column overhead in cyclic water tank；First it is distributed in advance through comb distributor；Then through dividing
After the dispersion of cloth device, water tank is returned；Water size is by valve and flowmeter control, display；Guarantee the level of distributor installation.Experiment
Arrange empty tower gas velocity F0Hydrodynamic calculations research under=1.5.Before experiment starts, blower is first opened, regulating butterfly valve aperture arrives
Required gas velocity；After a period of stabilisation, water circulating pump is opened, control valve is successively observed under each fluid flow from small to large
Kinetic energy factor, pressure drop, after stablizing, timing connects liquid metering, and records above-mentioned each measured value.
Using the concept of statistics large deviations, each distributed point outflow uniformity is assessed, relative deviation indicates each
The relative size of distributed point flow rate and average flow rate departure, works as relative deviation > 10%, in distributing homogeneity performance；Relatively partially
Poor 4%-6%, distributing homogeneity performance are good；Relative deviation < 4%, distributing homogeneity performance are excellent；Evaluation result shows: except individual
Except distributed point flow rate deviation is larger, for most of distributed point flow rate relative deviation within 4%, distributor performance is excellent.
The distributor few for cloth liquid point quantity can judge distributor by each cloth liquid o'clock as a distributed point with this
The quality of performance.It is as shown below to calculate each distributed point flow rate, relative deviation；
Each liquid distributing hole flow rate under same operating difference sprinkle density as shown in figure 4, it can be found that:
As sprinkle density increases, each liquid distributing hole flow rate difference reduces, and distribution tends to be uniform.This is because close with spraying
Degree increases, and height of liquid layer increases, and air-liquid mixes aggravation in calotte space, and liquid distributing hole is influenced gradually by dripping drops impact
Become smaller, each point flow rate tends to be uniform.
Fig. 5 is each cloth liquid point relative deviation, by evaluation of result, it is seen that when empty tower gas velocity is 7.5m3/(h.m2)
When, having 9 distributed point flow rate deviations is more than 4%；When empty tower gas velocity is 19.7m3/(h.m2) when, only 1 distributed point flow rate is inclined
Difference illustrates that the liquid distributor distributed mass is excellent, operating flexibility 1:2.6 more than 4%.
It means that in atmospheric distillation or compression rectification etc. in the insensitive component separation process of pressure drop, the New
Body distributor is able to achieve maximally utilizing for space in tower because of distinctive mass transfer function.
Distributor pressure drop is as shown in Figure 6:
The main reason for pressure drop generates is the castering action to partially liq, to cause pressure drop compared to traditional distributor
It is higher.By bottom gap, liquid is mixed in gas lift to calotte space, is broken, and gas and liquid two phases come into full contact with, and realize vertical
Mass transport process in body space, this is the main feature of CTST column plate.Fig. 6 shows through the air-liquid hybrid mode in riser,
One side liquid mixes in riser, on the other hand strengthens the flowing of liquid on catch tray, to eliminate above-mentioned tradition point
The problems such as concentration distribution difference present in cloth device, liquid level drop.
Each liquid distributing hole flow rate under same operating difference sprinkle density as shown in fig. 7, it can be found that；
Liquid level is about the same, this is because height of liquid layer increases as sprinkle density increases, air-liquid is in calotte sky
Interior mixing aggravation strengthens the flowing of liquid on catch tray, and influence of the dripping drops impact to liquid fluctuating gradually becomes smaller, liquid
Layer height difference becomes smaller.
Trough-tray liquid distributor proposed by the present invention with mass transfer function, is retouched by preferred embodiment
State, related technical personnel obviously can not depart from the content of present invention, in spirit and scope to structure as described herein and equipment into
Row change or appropriate changes and combinations, the invention of Lai Shixian this technology.In particular, it should be pointed out that all similar replacements and change
Apparent to those skilled in the art, they are considered as being included in spirit of that invention, range and content.
Embodiment 2
The parameter of bottom gap between CTST calotte two sides jet tray and catch tray in distributor is modified, setting height of base slot of the downcomer is 5mm,
Other parameters remain unchanged.Distribution performance test has been carried out to the distributor by above-mentioned steps.The result shows that: compared to implementation
Distributor in example 1, the distributor pressure drop under the conditions of same operation reduce that 50-70Pa, height of liquid layer increases 3- on catch tray
The cloth liquid point quantity of 5mm, cloth liquid point flow rate relative deviation greater than 4% is reduced to 1-3, and distributor quality gets a promotion, still
Operating flexibility falls to 1:2.2.
This is because height of base slot of the downcomer is reduced to 5mm, the channel that liquid enters CTST calotte becomes smaller, and resistance increases, identical item
The lifting capacity of liquid becomes smaller under part, and distributor pressure drop reduces, and the height of liquid layer also resulted on catch tray in comparison will
It increases, so each cloth liquid point flow rate just more tends towards stability.But liquid layer increases the drop for resulting in operating flexibility under the same terms
It is low.
Embodiment 3
Air rising hole perforated area parameter in distributor is modified, setting percent opening is 21%, and the width of rectangular opening is reduced to 22mm.
Other parameters remain unchanged.Distribution performance test has been carried out to the distributor by above-mentioned steps.The result shows that: compared to implementation
Distributor in example 1, the pressure drop under the conditions of same operation increase that 80-100Pa, height of liquid layer reduces 2-3mm, cloth liquid on catch tray
Cloth liquid point quantity of the point flow rate relative deviation greater than 4% reduces 1-2, not increased significantly.Distributor quality gets a promotion,
Operating flexibility rises to 1:3.2.
This is because the gas velocity after gas passes through becomes higher, corresponding CTST cap after reducing air rising hole perforated area
Pressure in cover will be lower, has more liquid to be inhaled into, and distributor pressure drop just has an apparent increase, but same liquid
The lifting capacity of body increases.Compared to the distributor in embodiment 1, height of liquid layer is declined, but the liquid on catch tray is not
Disconnected is inhaled into, sprays, this process strengthens the mobility of liquid, eliminates liquid level drop problem, concentration difference problem, together
When operating flexibility increase.
Unaccomplished matter of the present invention is well-known technique.
