Spray Cooling Tower
In a counterflow closed circuit cooling tower design the flow of the air is in the opposite direction of the spray water.
Spray cooling tower. These nozzles are high temperature resistant and have a non clogging design. In this article explained about basic concepts of cooling tower types of cooling towers formula for cooling tower efficiency. The inlet gas stream usually enters at the bottom of the tower. To make every cooling tower spray nozzle has inlet and outlet.
In bac s counterflow closed circuit cooling towers air travels vertically up through the unit while the spray water travels vertically down over the coil. A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact with each other in order to reduce the water s temperature. Benefits of cooling tower nozzle. Paharpur provides spiral spray nozzles made of inert polypropylene plastic to ensure hot water distribution is uniform over the fill pack.
A spray tower or spray column or spray chamber is gas liquid contactor used to achieve mass and heat transfer between a continuous gas phase that can contain dispersed solid particles and a dispersed liquid phase. Also brief about cooling tower mass balance of make up water requirement in system drift losses or windage evaporation losses blowdown or draw off. As this occurs water is evaporated reducing the temperature of the water being circulated through the tower. Gravity systems employed on bac s crossflow cooling towers feature hot water basins mounted on top of the tower above the fill.
Condenser water spray on to fill packaging. A series of spray nozzles in each hot water basin distribute the water evenly over the fill. The water is sprayed across the fill packaging. The entire system is housed inside a box shaped structure which also accommodates spray headers spray nozzles and louvers.
The water will evaporate into the air and carry heat away with it. The inlet connected with water pipe and the outlet has special design in order to make the water spraying uniform and continuous. Uniform distribution of water is crucial to maintain cooling tower efficiency. The louvers usually made of steel are placed on the sides to enhance natural circulation of air inside the cooling tower.
And then make the water drop down the cooling tower fills. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet bulb air temperature or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid to near. These droplets from the spray run down the fill packaging causing a thin film of water on its surface. Cooling towers employ either gravity distribution or pressurized spray systems to distribute water over the fill.
