[0002] A cooling tower is an evaporative heat dissipation device that uses the principles of evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate waste heat generated in industry or refrigeration and air conditioning to reduce the water temperature. However, a cooling tower requires a large amount of water to ensure the cooling effect. A large amount of water is lost during the cooling process, resulting in a waste of water resources.

[0003] At present, the measure for recovering steam from cooling towers is to install a grid-shaped condensing plate on the upper part of the spray section of the cooling tower to form a steam trap for recovery. For example, the water vapor recovery device for the air outlet of an open cooling tower disclosed in Chinese Patent Publication No. "CN218723269U" includes a shell body covered above the air outlet of the cooling tower, an air inlet is arranged at the lower part of the shell body; a plurality of condensation packing layers are arranged in sequence from top to bottom in the shell body, a water collecting tank is arranged below the condensation packing layer, and a water outlet hole is opened at the bottom of the water collecting tank; a fan is installed at the air outlet of the cooling tower, and the fan is driven by a motor.

[0004] The current water vapor recovery equipment all uses cold air as the heat exchange medium. Since the specific heat capacity of air is small, the heat exchange efficiency is low, which will lead to low water vapor condensation efficiency. In addition, the water vapor recovery equipment currently used is relatively closed, which is inconvenient to repair. Utility Model Content

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Refer to Figures 1-4 , a water vapor recovery device for a cooling tower, including a cooling tower 1 and a mounting frame 2 fixed on the top of the cooling tower 1. A collection box 3 is fixed on the top of the mounting frame 2. An air inlet mechanism 4 is communicated with the top of the collection box 3. A condensation box 5 is fixed inside the collection box 3. One side of the condensation box 5 is respectively communicated with a water inlet pipe 6 and a drain pipe 7, and one ends of the water inlet pipe 6 and the drain pipe 7 penetrate and extend to the outside of the collection box 3. A connecting column 8 is fixed at the bottom of the condensation box 5. The surface of the connecting column 8 is movably connected with an annular collection groove 9. One side of the annular collection groove 9 is communicated with a collection pipe 10. An installation mechanism 11 is arranged between the annular collection groove 9 and the connecting column 8; through the cooperation of the condensation box 5 with the water inlet pipe 6 and the drain pipe 7, the water vapor can be quickly condensed on the outer surface of the condensation box 5. The blower fan 44 at the top can blow cold air into the device for auxiliary condensation. The condensed water vapor will flow into the annular collection groove 9 and be collected through the collection pipe 10. By rotating the screw 113, the clamping block 122 can be retracted inward, and it is convenient to remove the annular collection groove 9 through the gap of the mounting frame 2 for replacement and cleaning. The efficiency is higher and the maintenance is more convenient when recovering water vapor.

[0021] In this embodiment, the air inlet mechanism 4 includes an exhaust duct 41. The exhaust duct 41 is communicated with the top of the collection box 3. A cross 42 is fixed inside the exhaust duct 41. A motor 43 is fixed at the bottom of the cross 42, and the output shaft of the motor 43 is fixed with a blower fan 44. The blower fan 44 can blow cold air into the device for auxiliary condensation.

[0022] Further, the installation mechanism 11 includes through holes 111 opened on both sides of the annular collection groove 9 and sliding grooves 112 opened on both sides inside the connecting column 8. A clamping component 12 is slidably connected to the inner sides of the two sliding grooves 112. The whole clamping component 12 slides in the sliding grooves 112. A screw rod 113 is rotatably connected to the inside of the connecting column 8 and the screw rod 113 is threadedly connected to the clamping component 12. The screw rod 113 can drive the clamping component 12 to move up and down.

[0023] Furthermore, the clamping component 12 includes a fixed frame 121 and a clamping block 122 movably connected to the inside of the fixed frame 121. The fixed frame 121 is threadedly connected to the screw rod 113. Strip-shaped holes 123 are opened on both sides of the fixed frame 121 and the strip-shaped holes 123 are inclinedly distributed. Positioning columns 124 are fixed on both sides of the clamping block 122 and the positioning columns 124 are slidably connected to the strip-shaped holes 123. A guiding groove 125 is opened in the connecting column 8 and the guiding groove 125 is slidably connected to the clamping block 122. The clamping block 122 is clamped with the through hole 111. The clamping block 122 will move horizontally under the action of the guiding groove 125. When the fixed frame 121 moves up and down, the inclined strip-shaped holes 123 on the fixed frame 121 can squeeze the clamping block 122 outwards and clamp it inside the through hole 111 to achieve fixation.

[0024] In addition, an annular gasket 13 is provided inside the annular collection groove 9. The upper and lower sides of the annular gasket 13 are respectively in contact with the condensation box 5 and the annular collection groove 9. The annular gasket 13 can increase the sealing performance of the contact part between the annular collection groove 9 and the condensation box 5 and prevent condensation water from leaking.

[0025] It should be noted that a sealing cover 14 is sleeved outside the mounting frame 2 and the sealing cover 14 is fixed on the surface of the mounting frame 2 through a fixing component. The fixing component is composed of bolts and screw holes. The sealing cover 14 can seal the mounting frame 2 and prevent water vapor from drifting out through the gaps.

[0026] Working mode: When recovering water vapor, a water supply pipe and a water return pipe are connected to the outside of the water inlet pipe 6 and the drain pipe 7. The water supply pipe can transport cold water into the inside of the condensation box 5, and the heated water can be discharged through the drain pipe 7. The water vapor in the cooling tower 1 will float upward and enter the collection box 3. When it contacts the outer surface of the condensation box 5 with a low temperature, the moisture in the water vapor will condense on the outer surface of the condensation box 5. The condensed water will flow into the inside of the annular collection groove 9 under the action of gravity. The collected condensed water can be discharged through the collection pipe 10 for collection. When replacing or overhauling the annular collection groove 9, the staff removes the sealing cover 14 and can operate from the position of the mounting frame 2. Rotating the screw 113 can drive the fixed frame 121 to move up and down. The fixed frame 121 moves in the sliding groove 112, and the clamping block 122 will move horizontally under the action of the guiding groove 125. When the fixed frame 121 moves up and down, the inclined strip-shaped holes 123 on the fixed frame 121 can squeeze the clamping block 122 outward and clamp it inside the through hole 111 to achieve fixation. Starting the motor 43 can blow cold air into the cooling equipment for auxiliary collection.
