Description
Technical field
The chemical industry equipment that the utility model relates to liquid distribution in packed tower and distributes, specifically a kind of highly dense spray point disc type liquid distribution trough.
Background technology
Packed tower is the mass transfer apparatus that gas-liquid directly carries out contacting, and the feature that in current oil, chemical industry, it is simple with structure, pressure drop is little, mass-transfer efficiency is high obtains to be applied more and more widely.In packed tower gas-liquid two-phase fluid to be uniformly distributed with fully contacting be ensure to carry out the necessary condition of efficient mass transfer.The liquid distribution trough with well distributed performance can provide uniform liquid distribution, prevents the generation of channel and serious wall stream, weakens the harmful effect of enlarge-effect and end effect, thus improve its efficiency.
Porose disc formula distributor is a kind of widely used liquid distribution trough.It has, and uniform function admirable, operating flexibility are large compared with high, liquid flux, Liquid Flow interferes with each other the advantages such as little; But because gas channel is less, in practical operation, when gas phase flow rate is larger, the required riser arranged is more, distributing disc does not have enough spaces open liquid phase pouring and falls hole, cause spray below riser uneven, cause the distributed effect of liquid sharply to decline, limit the scope that it uses.
Utility model content
The utility model object overcomes the deficiencies in the prior art, improves liquid distribution effect, provides a kind of highly dense spray point disc type liquid distribution trough.
The technical solution of the utility model is as follows:
A kind of highly dense spray point disc type liquid distribution trough, it is characterized in that, this distributor comprises base plate, outer ring, riser, liquid distributor, outer ring is positioned at around base plate, riser is distributed in base plate top, and liquid distributor is distributed in base plate bottom, and liquid distributor top is provided with branched pipe.Wherein outer ring is exposed in order to barrier liquid, and riser is as gas phase channel, and liquid distributor makes the intensive spray point of liquid phase be uniformly distributed.Branched pipe makes liquid material be more evenly distributed, and improves the operational efficiency of tower.
Preferably, above-mentioned liquid distributor length is 10 ~ 500mm.
Preferably, above-mentioned riser length is 150 ~ 300mm.
Preferably, above-mentioned branched pipe quantity is 3 ~ 6.
Preferably, above-mentioned branched pipe length is 20 ~ 200mm.
Preferably, above-mentioned branched pipe with vertical direction angle is 30 ° ~ 75 ° obliquely.
Preferably, above-mentioned outer ring height is higher than riser 20 ~ 200mm.
The utility model structure is simple, can select existing metal or nonmetallic materials, and adopts conventional processes to make, and easily implements.Also the dimensional parameters of all parts and all parts in highly dense spray point disc type liquid distribution trough reasonably can be designed according to different technological requirements.
Advantage of the present utility model and positive role are:
1. liquid distributor multi-limbed tube adds the spray point of disc type liquid distribution trough, and liquid material is more evenly distributed.Under the operating condition of high gas phase load, gas phase channel is more broad, thus effectively reduces gas phase drag, improves the operational efficiency of tower.
2. the branched pipe of liquid distributor overcomes the impact of gas phase channel on liquid distribution, and liquid can be made to be uniformly distributed on whole tower section.Below liquid distribution trough above filler, gas-liquid two-phase individual flow, thus effectively reduce gas phase to the disturbance of liquid phase and carry secretly.
3. liquid distributor multiple-branching construction makes parameter adjustment scope large, and operating flexibility is large, more easily controls, ensure that high efficiency and the reliability of technique during operation.
4., not easily there is the tendency causing " wall stream " to the flowing of tower wall, ensure that liquid distribution is even in the outer ring arranged.
5. the utility model liquid distribution trough structure is simple, pressure drop is little, distributed effect is good, and operating flexibility is high, can the liquid phase effectively reduced in gas phase carry secretly, is particularly useful for gas phase liquid phase load than high operating mode, can be widely used in the fields such as oil, chemical industry and environmental protection.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is further described, but does not limit protection domain of the present utility model.
Embodiment 1
The highly dense spray point disc type liquid distribution trough used in the rectifying column of a kind of diameter 1000mm.
This liquid distribution trough base plate diameter is 970mm, and after adding outer ring, external diameter is 980mm, and wherein outer ring height is 200mm.Base plate uniform pore openings 18 dress DN100 riser, riser height is 150mm.Liquid distribution trough base plate evenly opens 54 holes by regular hexagon between riser and fills liquid distributor respectively, pipe range is 200mm, and caliber is DN20.Every pipe racks 3 branched pipe, branch pipe range 50mm, direction in vertical direction with 45 ° obliquely.
After adopting above-mentioned highly dense spray point disc type liquid distribution trough, liquid phase is reduced to filler upper surface uniform flow along liquid distributor, reduces wall stream, the channelling effect of rectifying column.Under the prerequisite that other conditions are constant, the disposal ability of single rectifying column improves about 20%.
Embodiment 2
The highly dense spray point disc type liquid distribution trough used in the absorption tower of a kind of diameter 800mm.
This liquid distribution trough base plate diameter is 780mm, and after adding outer ring, external diameter is 790mm, and wherein outer ring height is 250mm.Base plate uniform pore openings 12 dress DN80 riser, riser height is 200mm.Liquid distribution trough base plate evenly opens 20 holes by regular hexagon between riser and fills liquid distributor respectively, pipe range is 400mm, and caliber is DN15.Every pipe racks 4 branched pipe, branch pipe range 70mm, direction in vertical direction with 30 ° obliquely.
After adopting above-mentioned highly dense spray point disc type liquid distribution trough, the top gas-liquid two-phase individual flow of absorption tower filler, thus effectively reduce gas phase to the disturbance of liquid phase and carry secretly, carried liquid quantity reduces about 50%, and maximum gas phase treatment amount can increase about 30%.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
