Description

A diversion structure of a cooling tower

technical field

The utility model belongs to the technical field of cooling towers, and in particular relates to a diversion structure of a cooling tower.

Background technique

The cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it to the atmosphere to reduce the water temperature. Its cooling is to use water and air to exchange heat and cold to generate steam. The steam evaporates and takes away heat to achieve evaporation. The principle of heat dissipation, convective heat transfer and radiation heat transfer is used to dissipate the waste heat generated in industry or in refrigeration and air conditioning to reduce the water temperature of the evaporative cooling device to ensure the normal operation of the system.

At present, the water flow in the cooling tower is mainly pumped into the water inlet pipe and poured into the filler. At the same time, the air at the bottom of the tower performs heat exchange and cooling on the hot water in the filler, and then the cooled water flow is directly poured into the reservoir by the filler. The tuyere is set at the lower part, and there is a certain distance from the filler, so that there is no diversion cooling structure in the distance from the bottom of the air flow to the filler, which reduces the utilization rate of wind energy, makes the hot water completely rely on the filler for cooling, and the cooling effect is not good. ideal.

In view of this, the utility model is proposed.
