[0002] As an important cold-end equipment in power plants, the efficiency of cooling towers directly affects the economic indicators of the units. After the circulating water absorbs heat in the condenser, it is sent to the cooling tower at a certain height above the ground. After being distributed by the water distribution pipe, it flows through various splashing devices. The splashing device distributes the water to the water filling below, exchanging heat with the countercurrent natural wind in the tower. Whether the splashing device can evenly distribute the circulating water to the water filling directly affects the heat exchange efficiency of the circulating water. Existing splashing devices are generally reflective splashing devices, and the circulating water cannot be evenly distributed on the water filling, and there will be a blank area for water spraying directly below.
