Embodiment 1
[0034] The cooling tower water distribution system of the present embodiment, as figure 1 , 2 As shown, four water supply pipes 2 are included. One end of each water supply pipe 2 is used to communicate with the central shaft 1 of the cooling tower, and the other end extends away from the central shaft 1. The four water supply pipes 2 are in the horizontal plane. The projection is in the shape of a "ten"; the water supply pipe 2 is provided with four ring-shaped water distribution pipes 3 centered on the central shaft 1 of the cooling tower and communicated with the water supply pipe 2. Each water distribution pipe 3 has a A plurality of injection devices are provided, and the injection devices include a low-pressure atomizing nozzle 4 directly installed on the water distribution ring pipe 3, and the nozzle direction of the low-pressure atomizing nozzle 4 is set upward;
[0035] in the vertical direction (such as figure 2 As shown), each water supply pipe 2 is inclined down...
Embodiment 2
[0040] The cooling tower water distribution system of this embodiment differs from Embodiment 1 in that, as image 3 As shown, the bottom of the outermost water distribution ring pipe 3-1 (that is, the water distribution ring pipe with the lowest elevation) is connected to a settling pipe 10 for slag discharge, and the connection between the settling pipe 10 and the outermost water distribution ring pipe 3-1 is provided. There is a valve 11; the end of the settling pipe 10 away from the outermost water distribution ring pipe 3-1 is used to connect with the sump of the cooling tower, and the settling pipe 10 is provided with a filter screen 12 for filter residues, and the settling pipe 10 is placed on the The upstream of the filter screen 12 is provided with a slag removal port 13 for removing the filter residue on the filter screen.
[0041] In the cooling tower water distribution system of this embodiment, since the nozzles spray water upwards, the flow rate of the circulatin...
Embodiment 3
[0043] The cooling tower of this embodiment, as image 3 , 4 As shown, it includes a tower 5, the tower 5 is provided with a packing layer 7 and a central shaft 1 located in the center of the tower, and a sump 8 is provided at the bottom of the cooling tower; the top of the tower inner packing layer 7 is provided with an embodiment In the cooling tower water distribution system described in 2, the water spray area 9 is below the packing layer 7; the water eliminator 6 is also provided above the cooling tower water distribution system in the tower tube 5; in the cooling tower water distribution system, the water supply pipe One end of 2 communicates with the central shaft 1, and the other end extends to the inner wall of the tower 5; image 3 The arrow above the middle water distribution ring pipe 3 is Figure 4 The injection direction of the middle and low pressure atomizing nozzles (the spout is arranged upwards); the settling pipe 10 connected with the outermost water dist...
