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.
Spray cooling tower.
The louvers usually made of steel are placed on the sides to enhance natural circulation of air inside the cooling tower.
A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature.
Cooling tower spray nozzles cooling tower fill packaging.
Uniform distribution of water is crucial to maintain cooling tower efficiency.
As this occurs water is evaporated reducing the temperature of the water being circulated through the tower.
Paharpur provides spiral spray nozzles made of inert polypropylene plastic to ensure hot water distribution is uniform over the fill pack.
The water will evaporate into the air and carry heat away with it.
The water is sprayed across the fill packaging.
In this article explained about basic concepts of cooling tower types of cooling towers formula for cooling tower efficiency.
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.
Also brief about cooling tower mass balance of make up water requirement in system drift losses or windage evaporation losses blowdown or draw off.
The entire system is housed inside a box shaped structure which also accommodates spray headers spray nozzles and louvers.
In a counterflow closed circuit cooling tower design the flow of the air is in the opposite direction of the spray water.
Benefits of cooling tower nozzle.
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.
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.
It consists of an empty cylindrical vessel made of steel or plastic and nozzles that spray liquid into the vessel.
These nozzles are high temperature resistant and have a non clogging design.
Cooling towers employ either gravity distribution or pressurized spray systems to distribute water over the fill.
These droplets from the spray run down the fill packaging causing a thin film of water on its surface.
A series of spray nozzles in each hot water basin distribute the water evenly over the fill.
The inlet gas stream usually enters at the bottom of the tower.
To make every cooling tower spray nozzle has inlet and outlet.
Gravity systems employed on bac s crossflow cooling towers feature hot water basins mounted on top of the tower above the fill.
