[0026] In the field of industrial circulating water, mechanical ventilation cooling tower as a key equipment, plays a vital role in heat exchange and circulating water cooling in the process of industrial production. In the cooling tower, along the base of the mechanical ventilation fan to the filler arc range of the cooling tower, will form a dead zone of air flow. In these dead zones, air cannot uniformly pass through the cooling tower filler, air stagnation cannot fully exchange heat with hot water, so that the hot water in the dead zone cannot be effectively cooled like other areas, resulting in smaller water temperature drop, and further causing the cooling effect of the overall cooling tower to be poor, the circulating water temperature to rise. This not only affects the normal operation of industrial production equipment, but also causes great waste of energy. With the continuous increase of equipment capacity, the air extraction dead zone area also expands, the equipment efficiency further reduces, and the energy consumption loss becomes more serious, which undoubtedly increases the production cost and investment cost.

[0030] In practical application, as Figure 1As shown, in the high-efficiency mechanical ventilation cooling tower, the shell 1 is provided with an air outlet 12, an air inlet 11, a first through hole 13 and a second through hole 14, the wind power assembly 3 is arranged at the air outlet 12 of the shell 1, the cooling assembly 2 is arranged below the wind power assembly 3 and at the upper end of the air inlet 11, and the flow guide plate 4 is arranged at the air outlet 12 of the shell 1 and used for guiding the air at the air outlet 12. The cooling assembly 2 comprises a cooling pipe 21, a backwater pipe 24, a heat exchange pipe 22, a heat exchanger 23 and a water reservoir 25, a plurality of third through holes are formed in the cooling pipe 21 and used for spraying cooling water to the filler in the shell 1 to reduce the temperature, one end of the backwater pipe 24 is communicated with the cooling pipe 21 through the first through hole 13, the other end of the backwater pipe 24 is communicated with the water outlet of the heat exchanger 23, the water reservoir 25 is arranged at the bottom of the shell 1 and used for recycling the cooling water of the cooling pipe 21, one end of the heat exchange pipe 22 is communicated with the water reservoir 25 through the second through hole 14, and the other end of the heat exchange pipe 22 is communicated with the water inlet of the heat exchanger 23.

On this basis, the flow guide plate 4 is arranged at the air outlet 12 and guides the air, so that the air can be discharged from the shell 1 according to the predetermined direction and path.

At the same time, the design of the water circulation system improves the utilization rate of water resources, reduces the operation cost and effectively solves the problem of low heat exchange efficiency of the mechanical ventilation cooling tower in the prior art.

[0031] For example, the flow guide plate is an arc-shaped flow guide plate. It can be understood that the above arc-shaped flow guide plate adopts a specific air flow arc design, which is optimized according to the principle of aerodynamics and can effectively reduce the resistance of the air passing through the filler water layer, ensure the smooth flow of the air and improve the heat exchange efficiency.

[0032] Exemplarily, the arc-shaped guide plate is a corrosion-resistant arc-shaped guide plate, for example, 316L stainless steel containing molybdenum element, which can significantly improve the resistance to pitting and crevice corrosion in a chloride environment. The arc-shaped guide plate is made of a material with good corrosion resistance, which can resist the erosion of humid, corrosive gas and cooling water in the cooling tower, thereby prolonging the service life of the guide plate.

[0033] Exemplarily, the arc-shaped guide plate is a high-temperature-resistant arc-shaped guide plate, for example, aluminum-based silicon carbide composite material (Al-SiC), which can withstand the high-temperature environment in the cooling tower and still maintain structural stability and flow guiding performance under high-temperature conditions.

[0034] Exemplarily, as shown in Figure 1 The wind power assembly 3 includes a driving mechanism 32 and a fan 31 connected to the driving mechanism. The fan 31 is used to extract the mist in the shell 1 from the shell, and the driving mechanism 32 can provide stable power for the fan 31. The fan 31 is used to extract the mist in the shell 1 from the shell to maintain the circulation and suitable humidity of the air in the shell 1.

[0035] Exemplarily, the cooling pipe is a spiral cooling pipe. The spiral structure increases the length of the cooling pipe and the flow path of the cooling water, so that the cooling water can be sprayed more uniformly on the filler, thereby improving the cooling effect.

[0036] In an alternative way, the cooling pipe is an array type cooling pipe. A plurality of cooling pipes are arranged in an array manner, which can realize uniform spraying of cooling water on a larger area, further enhancing the uniformity of cooling. Along the axial direction of the high-efficiency mechanical ventilation cooling tower, the spacing between adjacent cooling pipes is equal, and the spacing between adjacent cooling pipes is equal, which ensures the uniformity of the spraying of cooling water in the entire axial range, avoiding local differences in cooling effect.

[0037] Exemplarily, the shell is provided with a grid piece at the air inlet. The grid piece is detachably connected to the shell, which is convenient for cleaning, maintenance or replacement of the grid piece. At the same time, the grid piece can prevent larger debris from entering the interior of the cooling tower, protecting the internal structure of the shell.

[0038] Exemplarily, as shown in Figure 1 The high-efficiency mechanical ventilation cooling tower further includes a circulating device 5 arranged on the heat exchange pipe 22. The circulating device 5 is used to draw water in the water reservoir 25 into the heat exchanger, and then the water in the heat exchanger 23 flows back to the cooling pipe 21 through the backwater pipe 24, thereby improving the utilization rate of the cooling water.
