Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A spray device for a closed cooling tower includes a cooling tower main body 1 and a cooling mechanism 2, and the cooling mechanism 2 is arranged on the inner and outer surfaces of the cooling tower main body 1.

[0025] The cooling mechanism 2 includes a circulation unit and a spray unit. The spray unit is rotatably connected to the inside of the cooling tower main body 1, and the circulation unit is fixedly connected to the side of the cooling tower main body 1.

[0026] The main body 1 of the cooling tower is composed of a housing 101, support legs 102, a ventilation opening 103, an exhaust stack 104, a control panel 105, a support frame 106, and a heat exchanger 107. The support legs 102 are fixedly connected to the bottom of the housing 101. The ventilation opening 103 is provided on the surface of the housing 101. The exhaust stack 104 is fixedly connected to the top of the housing 101. The control panel 105 is fixedly connected to the surface of the housing 101 and is used to automatically adjust the power of the spray, the rotation speed of the water spray nozzle 214, and the spray angle. The support frame 106 is fixedly connected to the inside of the housing 101. The heat exchanger 107 is fixedly connected to the top of the support frame 106 and plays a major load-bearing role.

[0027] The circulation unit consists of a water suction pipe 201, a water pump 202, a circulation water pipe 203, an electric control valve 204 and a connecting pipe 205. The water suction pipe 201 is fixedly connected to the lower side of the outer shell 101. The water suction pipe 201 is connected to the circulation water pipe 203 which is connected to the connecting pipe 205, facilitating the realization of water circulation and improving the utilization rate of water resources. The water pump 202 is fixedly connected to the side of the outer shell 101. The circulation water pipe 203 is fixedly connected between the water pump 202 and the electric control valve 204. The electric control valve 204 is fixedly connected to the side of the outer shell 101. The connecting pipe 205 is fixedly connected inside the outer shell 101, facilitating the recycling of water resources. The spraying unit consists of a shunt pipe 211, a sealing shaft 212, a drain pipe 213, a water spraying port 214, a support plate 215 and an adjusting motor 216. The shunt pipe 211 is fixedly connected to the surface of the connecting pipe 205. The sealing shaft 212 is rotatably connected to the side of the shunt pipe 211. The drain pipe 213 is fixedly connected to the other side of the sealing shaft 212. One end of the drain pipe 213 far from the shunt pipe 211 is fixedly connected to the output end of the adjusting motor 216. There are three drain pipes 213, which are evenly distributed on the side of the shunt pipe 211, facilitating spraying from multiple angles, improving the coverage range of spraying, realizing the even distribution of sprayed water, improving the cooling effect, facilitating driving the drain pipe 213 to rotate by the adjusting motor 216, being able to adjust the spraying angle, and automatically adjusting the spraying according to the actual situation.

And the rotatable spraying method can adapt to different cooling requirements and operating conditions. By adjusting the rotation speed and angle of the spray head, the cooling effect can be optimized according to the actual situation. And since the sprayed water can evenly cover the packing, local overheating and corrosion of the packing layer are reduced, thereby prolonging the service life of the cooling tower.
