Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooling towers, in particular to a cooling tower comprising an anti-corrosion structure. BACKGROUND

[0002] Cooling towers are generally used in the manufacture of chemical products. The spray system in the tower evenly distributes water on the filler, which convects with air, and the water evaporates to absorb heat, thereby achieving the purpose of cooling the filler. However, as the cooling time increases, the high and low temperature water exchanges heat, and the sunlight outdoors causes the internal and external structures of the cooling tower to be easily oxidized and corroded, which seriously affects the performance of the cooling tower. Currently, corrosion-resistant materials such as stainless steel and glass steel are usually selected during manufacturing to effectively resist the corrosion of the internal medium of the tower body, or an anti-corrosion coating is used to solve the problem of corrosion of the tower body. However, this anti-corrosion method only reduces the possibility of corrosion of the cooling tower, and corrosion will still occur when the anti-corrosion coating is damaged, i.e. the problem cannot be fundamentally solved.

[0031] As Figures 1 to 3As shown, the cooling tower provided by the utility model is provided with annular filler structure in the cylindrical tower body 1, that is, the filler 2 is a hollow cylinder in the height direction of the tower body 1, so that the flowing area of hot water vapor in the tower body 1 is concentrated in the space surrounded by the filler 2 and the space between the filler 2 and the inner wall of the tower body 1; in addition, the air supply mechanism 4 is arranged on the tower body 1, that is, for blowing air for heat dissipation, according to the distribution of water vapor, the air supply mechanism with the bellows 41 is arranged, the air blower outside the tower body 1 blows air into the bellows 41, because the bellows 41 surrounds the periphery of the filler 2, the cold air can pass through the filler 2 into the axial area of the tower body 1 and flow upward in the area and finally escape from the tower body 1; the design increases the heat dissipation effect of the cooling tower.

[0032] As shown, Figure 3 The bellows 41 is a stainless steel box, the air blower blows cold air into the bellows 41, and the cold air passes through the holes in the box into the filler 2.

The function of the water collection tank 7 is to collect the cooling water passing through the packing material 2 for recooling and recycling, thereby reducing water waste. To further improve the anti-corrosion effect of the cooling tower, an anti-corrosion coating is applied to the interior of the tower body 1 and the surface of the water distribution pipe, which can effectively extend the service life of the cooling tower.
