The condensation ring is arranged above the discharge port of the cooling tower, the spiral fan blades are arranged in the condensation ring, and the condensation channels for condensing water vapor are formed between the adjacent spiral fan blades, so that when the water vapor entering the condensation ring rises to the upper part of the condensation ring through the condensation channels, the water vapor is condensed by the spiral fan blades due to the spiral bending characteristic of the spiral fan blades, and the water vapor is condensed by the condensation channels. When moving in the condensation channel, water vapor can be attached to the side wall of the spiral fan blade to flow, in the process, the water vapor makes contact with the spiral fan blade to slow down the flowing speed of the water vapor, meanwhile, the high-temperature water vapor makes contact with the spiral fan blade with the temperature lower than the temperature of the water vapor, the water vapor can be condensed to form water drops, and when the condensed water drops are too large, the water vapor is condensed. The water can slide into the cooling tower from the spiral fan blades under the influence of self gravity, so that water collection is completed, the water content in water vapor is reduced, and waste of water resources is avoided.

[0002] The applicant is a steelmaking company, which has built a large number of industrial circulating water cooling towers in its production plant. The main function of the cooling tower is to cool the high-temperature return water of the equipment for cooling and recycling. The main heat exchange principle is to use the fan to draw the ambient air into the tower upward, and spray the water downward through the spray pipe to complete the heat exchange between water and air, cooling and reuse. At the same time, it plays an important role in protecting equipment and saving energy.

[0003] However, when the cooling fan of the cooling tower is running, the fan exhausts steam upwards and carries a large amount of water, causing a large amount of evaporation of the circulating water, resulting in high water consumption, which not only increases costs but also wastes water resources, and at the same time has a certain impact on the environment around the cooling tower. Utility Model Content

[0013] The utility model has the following beneficial effects: the utility model sets a condensation ring above the discharge port of the cooling tower, and sets a plurality of spiral blades in the condensation ring, and forms a condensation channel for condensing water vapor between adjacent spiral blades.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] Example 1

[0018] like Figure 1As shown, this embodiment provides an energy-saving water collection device for an industrial circulating water cooling tower, which is used to reduce the leakage of large amounts of water vapor in the cooling tower and to reduce the waste of water resources. The water collection device includes a condensation ring 4 that can be installed above the cooling tower discharge port. The diameter of the condensation ring 4 is larger than the cooling tower discharge port, and the cooling tower discharge port can be completely covered, so that the water vapor discharged from the cooling tower discharge port can enter the condensation ring 4, and the water vapor is blocked and cooled in the condensation ring 4, thereby condensing into water. The condensed water droplets drip into the cooling tower through their own gravity, thereby completing water resource recovery.

[0019] In this embodiment, a coaxial positioning ring 8 and a positioning column 7 are provided in the condensation ring 4. The positioning ring 8 is located between the positioning column 7 and the condensation ring 4. The outer ring side and the inner ring side of the positioning ring 8 are fixedly surrounded by a plurality of vertically arranged spiral blades 6. The positioning ring 8 is connected to the outer circular side of the positioning column 7 and the inner ring side of the condensation ring 4 through the spiral blades 6. A condensation channel for the cooling tower water vapor to pass through is formed between the two adjacent spiral blades 6.

[0020] When the water vapor entering the condensation ring 4 rises to the top of the condensation ring 4 through the condensation channel, due to the spiral bending characteristics of the spiral fan blades 6, the water vapor can flow along the side walls of the spiral fan blades 6 when moving in the condensation channel. In this process, the contact between the water vapor and the spiral fan blades 6 can slow down its own flow speed. At the same time, the high-temperature water vapor contacts the spiral fan blades 6, which are lower than its own temperature, and will condense into water droplets when it is cold. When the condensed water droplets are too large, they will slide from the spiral fan blades 6 into the cooling tower under the influence of their own gravity, thereby completing the water collection, reducing the water content in the water vapor, and avoiding waste of water resources.

[0021] In this embodiment, a support frame is provided below the condenser ring 4. This support frame allows the condenser ring 4 to be positioned above the cooling tower outlet. In this embodiment, the support frame comprises a grid plate 3 and support members 1 positioned at the four corners of the bottom of the grid plate 3. To allow for height adjustment of the condenser ring 4, the support members 1 are hydraulic rods.

[0022] In this embodiment, the inner and outer sides of the positioning column 7, the spiral fan blades 6, the condensation ring 4 and the positioning ring 8 are all provided with an anti-rust coating to prevent the equipment from being in contact with water vapor for a long time, which may cause serious corrosion.

[0023] Example 2

[0024] This embodiment provides an energy-saving water collection device for an industrial circulating water cooling tower. The water collection device in this embodiment has most of the same structure as the water collection device in Example 1, except that: this embodiment can control the temperature of the spiral blades 6, and the positioning column 7, spiral blades 6, the ring body of the condensation ring 4, and the ring body of the positioning ring 8 are all set as hollow structures. The ring body of the condensation ring 4, the ring body of the positioning ring 8, and the interior of the positioning column 7 are interconnected through the spiral blades 6. The interior of the positioning column 7 is connected to the liquid outlet of the external liquid cooling device through a pipe, and the interior of the condensation ring 4 is connected to the liquid inlet of the external liquid cooling device through a pipe. Low-temperature liquid is injected into the spiral blades 6 through the external liquid cooling device to cool them, improve their condensation effect, and further recover the water source in the water vapor.

[0025] Example 3

[0026] This embodiment provides an energy-saving water collection device for an industrial circulating water cooling tower. The water collection device in this embodiment has most of the same structure as the water collection device in Example 1, except that: the cross-section of the spiral fan blade 6 is wavy, and one side of the spiral fan blade 6 is protruding outward in multiple places, and the corresponding protruding parts on the other side of the spiral fan blade 6 are concave inward. The protrusions and concavities increase the side area of ​​the spiral fan blade 6, increase the contact area with water vapor, and improve the condensation effect.

[0027] Example 4

[0028] This embodiment provides an energy-saving water collection device for an industrial circulating water cooling tower. The water collection device in this embodiment shares much of its structure with that of Example 1, differing in that a sunshade is provided above the condensation ring 4, the lower end of which is connected to the grille plate 3 via a support rod. The sunshade prevents the sun from shining on the spiral blades 6 during hot weather, causing them to heat up and affecting the condensation effect.

[0029] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
