The accessories in the cooling tower include filler, water distributor, fan, etc. The role of the water distributor is more important. Its role is to distribute the circulating water evenly on the filler. So, this article will take you to decompose the structure diagram and working principle of the cooling tower water distributor.
The cooling tower water distributor is a water distribution device for small and medium-sized circular counterflow cooling towers. It is a key component in the cooling tower. Its function is to distribute water evenly on the filler, increase the water vapor contact interface, make part of the water vaporize, take away heat, and play a role in reducing the water temperature. The shell is made of cast aluminum and cast iron, and the central part is divided into ordinary bearings and stainless steel bearings.
The cooling tower water distributor automatically rotates the water distribution using the backlash of the water. Below 80, it is composed of a phosphor bronze inner core and a nylon water distributor shell. Water distributors of more than 100 types use aluminum alloy with internal bearings, so it is easy to rotate, wear-resistant, corrosion-resistant, reliable, and has low water supply pressure, which is conducive to energy saving. The position of the water distribution hole is determined according to many practices to adjust the angle and change the speed of the water distribution device. Special requirements, color spray nozzle water distribution.
The working principle of the cooling tower water distributor The cooling water flows into the water distribution pipe through the water inlet pipe through the water inlet pipe, and then forms a water flow through the spray hole on the water pipe, and is sprinkled on the cooling tower filler. Because the diameter of the spray hole is relatively small, the water flow has a certain speed. According to the principle of acting force and reaction force, the water distribution pipe is rotated by the force opposite to the direction of the water flow, so that the water flow is continuously distributed on the packing of the cooling tower. The water adheres to the surface of the filler to form a water film flow, which increases the water vapor contact interface. The air exchanges heat with the water flow in the tower to exchange heat, which causes part of the water to vaporize, remove heat, and reduce the water temperature.
The function of the water distribution system is to evenly splash hot water onto the entire sprinkling filler. The performance of the water distribution will directly affect the uniformity of air distribution and the ability of the filler to play a cooling role. Recently, through continuous innovation and transformation, the water distributor has the characteristics of high rotation sensitivity, low water head, uniform water distribution, less floating water, flexible operation, long service life, convenient installation and easy repair.
