Product Description Product DescriptionThe trough liquid distributor is a high-performance liquid distributor used in the feed section of the packing tower. The trough liquid distributor has the advantages of easy installation, uniform liquid distribution, high spray point density, and extremely low pressure drop, and is currently widely used. A slot type liquid distributor is usually composed of a distribution groove (also known as a main groove or a primary groove) and a distribution groove (also known as a secondary groove or a secondary groove). The first stage slot initially divides the liquid into several streams through holes at the bottom of the slot, and distributes them to the liquid distribution slot below. The bottom (or wall) of the distribution slot is equipped with holes (or conduits) to evenly distribute the liquid on the packing layer. The slot type liquid distributor has great operating flexibility and excellent anti fouling and blocking performance. Especially suitable for separation platforms with atmospheric liquid loads and high viscosity liquids containing solids as floats. Due to its excellent distribution performance and anti fouling performance, it has a wide range of applications.Technical Specification Liquid Distributor ComparisonItemLadder typeSpray nozzle typePan with bottom holeTrough with bottom holePan with overflowTrough with overflowPowerpressuregravitypressuregravitygravitygravitygravityDistribution qualityMiddleHighLow to middleHighHighLow to middleLow to middlecapacitym3/(m2·h)0.25-2.50.25-10Wide rangeWide rangeWide rangeWide rangeWide rangeTower dia. /m>0.45AnyAnyAny, often<1.2Any, often>0.6Any, often<1.2Any, often>0.6Plugging degreeHighHighMiddle to highMiddleMiddleLowLowAir resistanceLowLowLowHighLowHighLow to highLevelness requirementsNoneLowNoneHigh at low loadHigh at low loadHighhighEffect of corrosionHighMiddleHighHighHighLowLowInfluence of liquid level fluctuationNoneSmallNoneMiddleMiddleBigBigEntrainmentHighLowHighLowLowLowLowWeightLowLowLowHighMiddleHighmiddleColumn DiametermmSpecific liquid loadM3/m2*hSystem fouling tendencyTurndown ratioSuitable type of liquid distributor250 - 9000.75 - 5Low - medium<10:1Trough type liquid distributor with sumpDeck type liquid distributor with orifices on drip tubes5 - 30Low - medium2:1Pan type liquid distributorTrough type liquid distributor with sump>30Low - medium2:1Pan type liquid distributorTrough type liquid distributor with sumpDeck type liquid distributor>9000.75 - 5Low - medium<10:1Trough type liquid distributor with parting boxDeck type liquid distributor with orifices on drip tubes5 - 30Low - medium2:1Trough type liquid distributor with sumpTrough type liquid distributor with parting boxDeck type liquid distributor>30Low - medium2:1Deck type liquid distributorTrough type liquid distributor with sumpMetal: Stainless steel 304, 304L, 316, 316L, 410, Carbon steel, other materials on request.Our Advantages1) The liquid distribution should be uniform and have a certain distribution point density. The unevenness of the liquid flow rate should be less than 10%;2) High operating flexibility, with an elasticity of over 10 * 1 for high elastic liquid distributors;3) Compact structure, occupying small space in the tower, with large gas flow (≥ 25%);4) Fully functional, such as liquid collection, distribution, and gas distribution functions;5) It can be used for liquids containing solid impurities and systems with foam;6) Low gas resistance and reduced operating pressure;7) Good mixing performance of liquid concentration and temperature;8) Anti fog foam and lifting film entrainment;9) Convenient manufacturing and installation, corrosion resistant;10) Widely applicable, such as atmospheric and pressurized vacuum operations for distillation, absorption, extraction, and other processes.Feature In order to improve the uniformity of fluid distribution in the pre distribution pipe of the trough liquid distributor, the uniform opening is changed into two opening modes, namely, non-uniform opening I and non-uniform opening (pressure relief opening) II. With the help of computational fluid dynamics software FLUENT, the k- ε The model numerically simulates and solves its three-dimensional flow field. The analysis shows that changing the diameter of the opening and adding a pressure relief hole results in the most uniform distribution of flow rate, static pressure, and turbulent kinetic energy in each hole, making it suitable for engineering operations. Structural form --The main slot and sub slot are integrated into one --The liquid first enters the main groove, flows horizontally into each sub groove, and then distributes to the surface of the filler from each sub groove --There is an anti impact plate in the main groove; Open overflow holes in the upper part of each slot and liquid distribution holes in the lower part --To prevent blockage, a filter frame is installed at the liquid inlet above the main tankApplications:Tower internalsUsed as an internal component in chemical equipment such as desulfurization towers, distillation towers, and absorption towers for mist or dust separation, achieving air purification, flue gas desulfurization, and water purification treatment purposes.Chemical industryIn the chemical industry, it is used in combination with wire mesh defoamers, wire mesh, and orifice corrugated fillers to eliminate or capture mist and liquid droplets entrained in the gas during processes such as catalyst and distillation, evaporation, and absorption.PetroleumUsed for physical or mechanical separation of crude oil dehydration, crude oil degassing, and gas-liquid separation in the petroleum refining process.OthersSeparation and filtration devices in light industrial manufacturing processes; Even in fields such as medicine, aerospace, and machinery, they are widely used.
