Description

A kind of liquid distributor
Technical field
This utility model belongs to liquid distribution technical field, is related to a kind of realize that material is uniform by special cloth shower nozzle Liquid distributor, more particularly to a kind of high-efficiency liquid distributor.
Background technology
As the continuous improvement of living standards of the people, environmental conservation are increasingly taken seriously, fuel in combustion can Produce the pollutant such as sulfur dioxide, nitrogen oxides and nitric oxide, wet absorption flue gas technology is most widely used.Filler The core on absorption tower is the distribution situation of liquid in tower, how to ensure the uniform of packed absorber interior flow field, it is desirable to gas-liquid Contact area is big, and the absorbing reaction of gas is good, and the pressure loss is little, and is applied to large volume handling.In absorption tower operation at present The problem of being primarily present is, when absorption tower host groups at full capacity when operational excellence, but during motor unit underrun, occur inhaling Rate of producing effects is unstable, operation conditions fluctuation, often up to less than the problem of expected efficiency, main cause be gas velocity distribution it is uneven, The problems such as gas-to-liquid contact effect is poor, the time of contact of high speed gas and serosity is not enough.Spray system used in absorption tower, be The huge water distribution system of multilamellar is formed using up to a hundred nozzles, the key problem of such spray column is jet expansion little Yi blockings, Cause water shortage and the water distribution of spray uneven, affect gas-liquid mass transfer, gas-to-liquid contact is insufficient to cause desulfuration efficiency low.So The water-distributing device for seeking the tower spray system that a kind of interior flow field is uniform, gas liquid interfacial area is big, operating flexibility is big has important Meaning.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of liquid distributor, For current packed absorber exist gas-to-liquid contact effect is poor, packed absorber water distribution system water distribution inequality, operating flexibility are low, A kind of spray system operational stability difference problem, there is provided absorption tower by special three splashing jet, using such spray water distribution System improves uniformity of water distribution, can alleviate the gas-to-liquid contact inequality caused because of conditions such as unit load change, quantity of circulating water changes The problem that absorption efficiency is low is caused, the stability of whole system operation is enhanced.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of liquid distributor, the water-locator are made up of two layer system, set up four separately per layer system center water inlet Main cloth main pipe, four main cloth main pipes are uniformly distributed, and set up cloth arm per root in main cloth main pipe separately, and each cloth arm is divided into Eight branch road petal types are arranged, and every cloth arm is provided with three splashing type external screw thread shower nozzle, four main cloth main pipes of two layer system Project alternate dislocation at 45 °.
Described three splashing type external screw thread shower nozzle by water inlet, upper water drenching hole, middle water drenching hole, venturi import, lacing wire, on splash Water pond, middle splash box, under splash dispersion cone composition, by the upper splash box of lacing wire connection, upper splash box passes through for wherein venturi import Splash box in lacing wire connection, by splashing dispersion cone under lacing wire connection, described venturi import lower end is provided with into water middle splash box Mouthful, water drenching hole is provided with the middle of upper splash box, is provided with middle water drenching hole in the middle of middle splash box.
Described every layer system can adopt pipe-disc type cloth, and main cloth system arranges one layer of four main cloth main pipe, per root Main pipe is alternate in 90 °, sets up three splashing type external screw thread shower nozzle in each main pipe.
Described cloth arm is determined according to the dimensions length of absorption column of gas.
The beneficial effects of the utility model are:
1)Using the three splashing jet after improvement:Water enters three splashing jet after improvement, first leads in the water inlet of shower nozzle Cross venturi import and form conical fluid, the conical fluid impact circular cone cloth water surface makes water go out then certainly along cloth water surface level stream By falling, the impact of current offside wall is this not only reduces, and avoids water impact filler from extending gas-liquid contact time.
2)Water distribution is uniform, operating flexibility is big:The bulk water curtain of three layers of uniform thickness is ejected in the range of flow of design, The water curtain size and thickness for ejecting is relevant with the water yield of water and pressure, but under more water-distribution nozzle, the point of local Water distribution is more uniform, petal type and pipe-disc type as main water distributor, three layers of water curtain that each water distribution head is formed full model from top to bottom It is evenly distributed in enclosing, covers all around whole absorption tower, water curtain is smashed to form drop by the flue gas of rising, so as to high degree expands Big gas-to-liquid contact face.And such shower nozzle water distribution belongs to without compress water, low for hydraulic demand, the operating flexibility of single spraying head is big, So absorption mass-transfer efficiency can be improved.
3)Shower nozzle blocking probability is low, easy to maintenance:Such cloth water-bound be can be seen that from water distributor structure form, it is maximum In acceptable absorbing liquid, the size range of particulate matter can be passed through less than two grades of cloth liquid disk diameters of three splashing jet, Never there is blocking, and the processing technology of such shower nozzle is simple, it is adaptable, connect with the screw thread that is connected by of main cloth system Connect, be easy to maintenance.
