Seawater Filtration Air Cooler Heat Exchanger Duplex Steel Air Cooler Heat Exchanger

Seawater filtration air cooler heat exchanger duplex steel air cooler heat exchangerIntroduction of air-cooled heat exchangerAir-cooled heat exchanger is a cooling equipment used in refining, chemical, metallurgy, power station and other industries. It is used to cool various industrial media. Compared with other cooling equipment: Advantages, air-cooled heat exchangers use air as the cooling source, energy and water saving effect is very significant; Disadvantages, large footprint, large one-time investment.Air cooler classification:According to the cooling medium is divided into:Dry air cooler Wet air cooler Surface evaporative air coolerAccording to the heat transfer element is divided into:Tubular heat exchanger Plate air cooler, etc.Air cooler application scope:Dry air cooler can cool the medium to 200C above ambient temperature;Wet air cooler can cool the medium to 3~50C above the ambient temperature;Surface evaporative air cooler can cool the medium to close to the ambient temperature, and in special cases can be cooled to lower than the ambient temperature. It can replace the water cooler.Introduction of surface evaporative air coolerSurface evaporative air cooler is a new type of air cooler that integrates water cooling and air cooling, heat transfer and mass transfer processes into one and has the advantages of both; it is an efficient condensing and cooling equipment with high heat transfer efficiency, low investment, low operating cost, compact structure, energy saving and water saving, which is used in refining, chemical industry, electric power, metallurgy, refrigeration, light industry and other industries. So far, evaporative air-cooling has been widely used in ketone benzene units, gas separation units, alkylation units, propane deasphalting units, coking units, distillation units, catalytic units, reforming units, sulfur recovery units, light hydrocarbon recovery units, etc. in major petrochemical enterprises in China.Structure of surface evaporation air coolerComposition:Fan, heat exchanger stainless steel tube, finned tube, spraying system, light tube bundle, water tankFeatures:Fan - induced draft fan; finned tube - bimetallic rolled tube; spray system - stainless steel, double water pump light tube bundle - surface heat-incorporated zinc, silk plugged tube box; water tank - surface FRP anti-corrosionSurface evaporation air cooler mechanismHeat transfer mechanism:The water film is formed on the surface of the light pipe, and the heat is taken away by the evaporation of the water film. Both the temperature rise of the air and the temperature rise of the water take away heat, and the latent heat of vaporization of the water takes away heat.Scope of application:It is used for the condensation cooling of low temperature process medium with an inlet temperature of 160-80ºC, and the outlet temperature of the medium can be cooled to close to the ambient wet bulb temperature. It can replace the rear water cooler and wet air cooler.Surface evaporation air cooler process selectionProcess calculation method.The calculation method is different from the traditional air cooler, which is beyond the scope of air cooler; at present, only our company has the ability to calculate.Surface evaporative air coolerSurface evaporative air cooler development direction.Improve the corrosion resistance of heat exchanger tube Solve the problem of decreasing cooling effect Solve the problem of icing in winter Improve the corrosion resistance of water tank and shutter Improve the life of fan bearingSurface evaporative air coolerMeasures taken:Heat exchanger tube corrosion problemMeasures: heat invasion zinc, composite aluminum tube, heat exchanger stainless steel tubeCooling effect decline Cause: light tube surface scaling Measures: effective control of media into the evaporation section temperature, increase the spray space and strict control of water quality Winter icing problemsMeasures: design concept changeFan bearing life is lowMeasures: the use of bearings and bearing housing integrated whole bearingWater tank, louver corrosionMeasures: sandblasting and rust removal before painting and water tank surface FRP anti-corrosionSurface evaporation air cooler economyGas separation unit propylene tower top condenser (compared with water cooler)Surface evaporation air cooler economicsCoking unit fractionation tower top air cooler (compared with dry air cooler plus post water cooler)Surface evaporative air cooler operabilityAnnual operating cost is about 30% of post water cooler and 65% of wet air cooler. Floor space is approximately 50% of dry air plus aftercooling and 43% of wet air cooling.
