The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1, the utility model provides a technical solution: a spray cooling tower for oxygen production equipment, including a tower body 1, a base 2, a pool 3, a filling port 4, a nozzle 5, a water distribution pipe 6, a water collecting Device 7, drive motor 8, fan 9, mist catcher 10 and water return pipe 12; the bottom of the tower body 1 is supported by the base 2, a pool 3 is provided at the bottom of the inner side of the tower body 1, and a drive motor is fixedly installed on the top end cover 8; the drive motor 8 is connected to the fan 9 through a drive shaft, and the fan 9 is supported by a support rod 91 welded on the inner bottom of the tower body 1; the upper end of the pool 3 is sequentially provided with a filling port 4, a nozzle 5, a water distribution pipe 6 and The water eliminator 7; the top of the tower body 1 is integrated with the air cylinder 11; the inside of the air cylinder 11 is equipped with a mist catcher 10; the left side of the outer end of the tower body 1 is connected to the pool 3 through a pipeline 101, and A control valve 102 is provided on the pipeline 101 .

A centrifugal atomization device is evenly installed on the water distribution pipe 6, and the water distribution system in the water distribution pipe 6 and the centrifugal atomization device form a set of integral cooling elements. 4 Spray water downward through the nozzle 5, and under the action of the fan 9, an atomized state is formed, so that the circulating water mist is suspended in the cooling tower body 1 and exchanges heat with the air, thereby realizing the effect of cooling and cooling. According to the structure of the tower body, Corresponding water eliminators 7 are arranged to prevent floating water, and the structure of the whole tower is greatly simplified. The right side of the outer end of the tower body 1 is also connected with a water return pipe 12, the end of the water return pipe 12 is connected in the pool 3, and the upper end of the water return pipe 12 is equipped with an alarm device 13 and a limiting orifice 14. The water return pipe 12 is provided with signal detection for liquid flooding and entrainment of a large amount of free water. After the free water is separated, it returns to the pool 3 in the tower body 1 through the flow-limiting orifice 14 .

The structure and working principle of the utility model: the circulating water forms a suspended water mist in the tower body 1 through the centrifugal atomization device to exchange heat with the cold air. In the mist-like interval formed in the tower body 1, as long as the cooling tower does not stop running, the circulating water will always be in contact with the cold air in the form of "mist", and the specific surface area of the contact is larger than the film-like water dispersed by the filler. The surface area increases by 5% to 10%. The spray cooling tower cloth water adopts the upward spray method, and the spray space is kept at about 4m. The circulating water and cold air form two heat exchange cooling processes in the tower, namely two processes of forward flow and counter flow. At the same time, the water mist will also meet the rising air flow during the falling process, which delays the falling speed of the water particles, thus ensuring the heat exchange time.
