Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a guiding device for the air duct of a cooling tower. Background Art

[0002] A cooling tower is an important industrial device, mainly used for cooling process water or return water to maintain the working efficiency of various industrial devices and systems. Cooling towers are widely used in fields such as electric power, chemical industry, air conditioning, and manufacturing.

[0003] The upper end of the tower body of the cooling tower is provided with an air duct, and a fan is arranged inside the air duct. When the fan operates, it drives the hot air inside the tower body to flow, and the hot air flows to the outside through the upper opening of the air duct, thereby accelerating the cooling of water. However, during the process of being driven by the fan, the hot air will carry a large amount of moisture, and the moisture flows to the outside with the hot air, resulting in waste of water resources. Summary of the Invention

[0004] In order to solve the problem that when the fan in the air duct on the cooling tower drives the hot air inside the tower body to flow out, a large amount of moisture will be carried, the utility model provides a guiding device for the air duct of a cooling tower, which can recover the moisture in the hot air and reduce the waste of water resources.

[0005] In order to solve the above problems, the technical solution of the utility model is as follows:

[0006] A guiding device for the air duct of a cooling tower includes a tower body. The upper end of the tower body is communicated with an air duct, and further includes a bearing cylinder, a guide plate, and a condensation member. The bearing cylinder is arranged inside the air duct. A spiral guide plate is sleeved and fixed outside the bearing cylinder, and the outer edge of the guide plate is fixedly connected to the inner wall of the air duct. The condensation member includes a sleeve, a water inlet pipe, and a water outlet pipe. The sleeve is sleeved and fixed outside the air duct through connection holes opened at the upper and lower ends. Water holes I are arranged at intervals along the spiral direction of the guide plate on the guide plate. Both ends of each water hole I penetrate the inner and outer sides of the guide plate respectively. A water hole II is arranged on the air duct opposite to one end of the water hole I, and a water hole III is arranged on the peripheral wall of the bearing cylinder opposite to the other end. The water outlet end of the water inlet pipe penetrates the air duct and is connected to the upper end of the bearing cylinder, and the water inlet end of the water outlet pipe is communicated with the inside of the sleeve.

[0007] Further, a fan is arranged at the upper end of the air duct, and the motor of the fan is connected to the inner wall of the air duct through a plurality of connecting rods.

[0008] Further, the bearing cylinder is arranged inside the air duct below the fan and is coaxially arranged with the air duct. The bearing cylinder is a cylindrical body with an open upper end and a closed lower end.

[0009] Further, the water holes I, II, and III are all circular holes with the same diameter, and the water hole I is coaxially arranged with the water holes II and III on both sides.

[0010] Further, each of the first water holes, together with the second and third water holes on both sides, forms a communication hole, and the bearing cylinder and the sleeve are communicated through the communication hole.

[0011] Further, the guide plate is a plate made of stainless steel material, and a spiral channel is formed jointly among the guide plate, the bearing cylinder and the air duct; grid-like protrusions are arranged on the upper and lower side surfaces of the guide plate.

[0012] By the above technical solution, the beneficial effects of the present utility model are as follows:

[0013] When the hot air in the tower body is driven by the fan to flow upward, the hot air flows in a spiral shape through the spiral channel, and the cooling water flows to cool the guide plate. Therefore, the spiral channel can cool the liquid droplets in the hot air, the cooled guide plate can contact the hot air, condense the liquid droplets in the hot air, and make the condensed water return to the tower body again; reduce the moisture flowing out of the air duct along with the hot air.

[0014] The grid-like protrusions on the guide plate of the present utility model can increase the contact between the hot air and the guide plate, so that more moisture in the hot air can be condensed by the guide plate. Description of the Drawings

Detailed Embodiments

[0019] The present utility model will be further described below in conjunction with the drawings and detailed embodiments:

[0020] As Figures 1 to 3As shown in the figure, a guiding device for the cooling tower air duct includes a tower body 1. The upper end of the tower body 1 is connected to an air duct 2. The air duct 2 is a cylindrical body with openings at both ends. It also includes a bearing cylinder 3, a guide vane 4, and a condensation member. The bearing cylinder 3 is arranged inside the air duct 2. A spiral guide vane 4 is sleeved and fixed outside the bearing cylinder 3. The outer edge of the guide vane 4 is fixedly connected to the inner wall of the air duct 2. The condensation member includes a sleeve 5, a water inlet pipe 7, and a water outlet pipe 8. The sleeve 5 is a cylinder with closed ends and an inner diameter larger than the outer diameter of the air duct 2. The sleeve 5 is sleeved and fixed outside the air duct 2 through connection holes 6 opened at the upper and lower ends. Water holes 9 are arranged at intervals along the spiral direction of the guide vane 4 on the guide vane 4. Both ends of each water hole 9 penetrate the inner and outer sides of the guide vane 4 respectively. A water hole 10 is provided on the air duct 2 opposite to one end of the water hole 9, and a water hole 11 is provided on the peripheral wall of the bearing cylinder 3 opposite to the other end. The water outlet end of the water inlet pipe 7 penetrates the air duct 2 and is connected to the upper end of the bearing cylinder. The water inlet end of the water outlet pipe 8 is communicated with the inside of the sleeve 5.

[0021] A fan 14 is provided at the upper end of the air duct 2. The fan 14 drives the air in the tower body 1 to flow upward through the air duct 2. The motor of the fan 14 is connected to the inner wall of the air duct 2 through a plurality of connecting rods 13.

[0022] The bearing cylinder 3 is arranged inside the air duct 2 below the fan 14 and is coaxially arranged with the air duct 2. The bearing cylinder 3 is a cylindrical body with an open upper end and a closed lower end.

[0023] The water holes 9, water holes 10, and water holes 11 are all circular holes with the same diameter. The water holes 9 are coaxially arranged with the water holes 10 and water holes 11 on both sides.

[0024] Each water hole 9 and the water holes 10 and water holes 11 on both sides together form a communication hole. The bearing cylinder 3 and the sleeve 5 are communicated through the communication hole.

[0025] The guide vane 4 is a plate body made of stainless steel material. The stainless steel material has excellent heat conduction ability and corrosion resistance. A spiral channel is jointly formed among the guide vane 4, the bearing cylinder 3, and the air duct 2. Grid-like protrusions 12 are provided on the upper and lower side surfaces of the guide vane 4. The grid-like protrusions 12 are beneficial to the formation of gas turbulence.

[0026] During use, cooling water is introduced into the water inlet pipe 7. The cooling water enters the bearing cylinder through the water inlet end of the water inlet pipe 7. The cooling water in the bearing cylinder enters the sleeve 5 through a plurality of communication holes. The cooling water in the sleeve 5 flows out through the water outlet pipe 8. When the cooling water flows through the flow guide plate 4 via the communication holes, the flow guide plate 4 is cooled, and the temperature in the spiral channel also decreases. The fan 14 operates to drive the hot air in the tower body 1 to flow upward from bottom to top in the air duct 2. Since the spiral flow guide plate 4 is provided in the air duct 2, the hot air entering the air duct 2 is in a spiral shape and flows upward from bottom to top in the spiral channel. Therefore, the spiral channel can cool the droplets in the hot air. When the hot air flows through the spiral channel, the flow path has a certain rotational characteristic, resulting in vortices and non-linear flow during the flow of the hot air. The cooled flow guide plate 4 can contact more with the hot air, condensing the droplets in the hot air. The droplets accumulate on the flow guide plate 4 and can gather into large droplets. The large droplets flow downward along the flow guide plate 4 and return to the tower body 1 again.

[0027] The flow guide plate 4 is provided with grid-like protrusions 12, which can increase the surface roughness of the flow guide plate 4. The grid-like protrusions 12 can break the boundary layer smoothness between the hot air and the flow guide plate 4 in the spiral channel, enabling the hot air to form more turbulence in the spiral channel, thereby enabling the hot air to contact the flow guide plate 4 more, and further enabling more moisture in the hot air to be condensed and refluxed.

[0028] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Without departing from the spirit of the present invention, that is, within the scope of disclosure, any equivalent or equivalent deformation or replacement of the technical solutions of the present invention belongs to the protection scope of the present invention.
