Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower water outlet equipment, in particular to a cross-flow cooling tower uniform water outlet device. Background Art

[0002] A cooling tower is a device that uses water and air to exchange heat and generate water vapor. The water vapor evaporates and takes away heat to achieve evaporative heat dissipation and convection heat transfer. Cooling towers are used in the industrial and construction fields to cool down the cooling water and achieve the purpose of recycling cooling water. The cooling water system is generally equipped with multiple cooling towers, and each commonly used cross-flow cooling tower has four water outlets. Due to the unequal transmission distances and the presence of air in the pipeline when the cooling tower is shut down, the hydraulic balance and residual gas assist during the actual operation of the cooling tower cause an imbalance in the water flow at the cooling tower outlet, which seriously affects the actual heat dissipation effect. In view of this, we propose a cross-flow cooling tower uniform water outlet device. Utility Model Content

[0023] See also Figure 1-3 The utility model describes the above technical solution in detail through the following embodiments:

[0024] A uniform water outlet device for a cross-flow cooling tower comprises an outer cylinder 1, an intermediate isolation plate 2 is fixedly installed inside the outer cylinder 1, a first stainless steel air pipe 3 and a second stainless steel air pipe 8 are fixedly installed on both sides of the intermediate isolation plate 2, a plurality of water holes 4 are opened on the intermediate isolation plate 2, a bottom flange 5 is fixedly installed at the bottom of the outer cylinder 1, a side flange 7 is fixedly installed on the side of the outer cylinder 1, and a semicircular stainless steel plate 6 is installed at the bottom of the right side of the outer cylinder 1.

[0025] It should be noted that the semicircular stainless steel plate 6 is sealedly connected to the inner wall of the outer cylinder 1 and the middle isolation plate 2 .

[0026] As a preference of this embodiment, the outer cylinder 1 is cylindrical.

[0027] As a preferred embodiment of the present invention, the middle isolation plate 2 is installed at the center of the outer cylinder 1 and evenly divides the outer cylinder 1 into two left and right semi-cylinders.

[0028] As a preferred embodiment of the present invention, the water holes 4 are transversely staggered with each other and are interconnected. The water holes 4 are provided to realize the communication of the water channels between the left and right parts of the outer cylinder 1 .

[0029] As a preferred embodiment of the present invention, the relationship between the total cross-sectional area S of the water holes 4 and the cross-sectional area S1 of the outer cylinder 1 is: 0.4S1<S<0.6S1.

[0030] As a preference of this embodiment, the position of the lowest water hole 4 is aligned with the center of the side flange 7, and the vertical distance D between the lowest water hole 4 and the bottom flange 5 satisfies: 220 mm≤D≤320 mm.

[0031] As a preferred embodiment of the present invention, the inner diameter of the outer tube 1 and the inner diameters of the water inlet and outlet at the bottom and side are the same as the inner diameter of the external pipe 13 on the cooling tower. Regardless of whether the on-site working conditions are water inlet at the bottom and water outlet at the side, or water inlet at the side and water outlet at the bottom, it is sufficient to install and connect them according to the external standard flange.

[0032] As a preferred embodiment of the present invention, the bottom gas outlet position of the first stainless steel air pipe 3 is aligned with the upper edge of the bottom flange 5, the top extends out of the outer tube 1 and is sealedly connected to the outer tube 1, and the bottom gas outlet position of the second stainless steel air pipe 8 is aligned with the left edge of the side flange 7, the top extends out of the outer tube 1 and is sealedly connected to the outer tube 1.

According to the side-inlet and bottom-out water flow direction, when the water flow changes in the outer tube 1, the comparison between the air flow pressure in the left and right areas and the external atmospheric pressure also changes accordingly. Manually adjusting the opening of the ball valve above the first stainless steel air pipe 3 and the second stainless steel air pipe 8 can quickly adapt to the internal water flow changes and realize uniform water distribution at the cooling tower outlet;

According to the bottom inlet and side outlet water flow direction, when the water flow changes in the outer tube 1, the air pressure in the left and right areas and the external atmospheric pressure also change accordingly. Manually adjusting the opening of the ball valve above the first stainless steel air pipe 3 and the second stainless steel air pipe 8 can quickly adapt to the internal water flow changes and realize uniform water distribution at the cooling tower outlet.
