The two diversion plates are respectively connected to the first diversion pipe 5 and the second diversion pipe 6. Nozzles 10 are evenly installed at the bottom of the horizontal connecting pipe 7, the vertical connecting pipe 8, and the side connecting pipe 9. A water curtain screening mounting frame 11 is fixedly installed on the inner side of the cooling tower body 1 at the bottom of the distribution plate.
