Uniform water distribution device realizing variable flow of reverse-flow cooling tower

Abstract

The invention relates to a uniform water distribution device realizing variable flow of a reverse-flow cooling tower, and the uniform water distribution device comprises a water inlet pipe (1) and a horizontal water distributor, wherein the water inlet pipe (1) is installed inside a cooling tower body or the horizontal water distributor is installed on the water inlet pipe (1) outside the tower body, the horizontal water distributor comprises a plurality of water distribution pipes (14) and a plurality of water distribution nozzles (12), a water inlet of each water distribution pipe (14) is connected with the water inlet pipe (1), the water distribution nozzles (12) are respectively installed on a pipe body of a corresponding water distribution pipe (14), and a plurality of water distribution nozzles (12) on the water distribution pipe (14) are communicated with one another, and each water distribution nozzle (12) is higher than the water distribution pipe (14). Due to the adoption of the uniform water distribution device, the defect that the nozzle or the rotary water distributor and the rotary nozzle are easy to damage because of movable parts can be simultaneously solved.

Description

technical field [0001] The invention relates to a counterflow cooling tower, in particular to a counterflow cooling tower water distribution device, in particular to a counterflow cooling tower uniform water distribution device under variable flow. [0002] Background technique [0003] The counter-flow cooling tower is an indispensable heat dissipation device in the central air-conditioning system. Its function is to evenly sprinkle the hot water entering the tower onto the filler below. By increasing the contact area with the air, it can fully exchange heat with the cold air to reduce the water temperature. Purpose. [0004] The water distribution device generally has the following three types, such as figure 1 As shown, one is to install a horizontal water distributor on the water inlet pipe 1. Generally, it consists of three pipes and 4 channels. There are small holes 3 on the side of the horizontal water distributor. When the water flow is sprayed out, the reverse ac...

It will also cause uneven water distribution when the flow rate is small

[0006] There is also a method of using rotating nozzles for water distribution, that is, using pressure to push the nozzles to rotate quickly to achieve uniform water distribution. However, when the water flow is small, in addition to the fact that the nozzles cannot rotate, there will also be too much water near the main pipe when the water flow is small. The phenomenon of no water in the far nozzle

It will also cause uneven water distribution when the flow rate is small

At the same time, such a structure is easy to damage the nozzle due to the rapid rotation of the nozzle
