Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cooling towers, in particular to a countercurrent energy-saving natural ventilation cooling tower. Background Technique
[0002] The countercurrent energy-saving natural ventilation cooling tower is an efficient, energy-saving and environmentally friendly cooling device. Its working principle is to utilize the countercurrent contact of air and water, and reduce the water temperature through the evaporation heat dissipation of water. Its structure is relatively simple, and the natural ventilation method reduces the wear of mechanical components, reduces the maintenance and repair costs, and does not produce harmful substances during operation, which is friendly to the environment.
[0003] The existing natural ventilation of cooling towers is mainly through two methods. One is that the outside wind blows into the cooling tower; the other is the heat exchange inside the cooling tower. The air at the bottom of the tower is heated and rises to form a pressure difference with the outside, and is inhaled from the outside. In order to ensure the cooling effect, the existing cooling towers are built higher to accelerate the air circulation in the tower, reducing the retention time of natural wind in the tower, resulting in insufficient utilization of natural wind. Content of the Utility Model
[0004] The purpose of the utility model is to provide a countercurrent energy-saving natural ventilation cooling tower to solve the above deficiencies in the prior art.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A countercurrent energy-saving natural ventilation cooling tower includes a tower body. An air inlet is opened at the lower side of the tower body. A wind guiding component is installed inside the tower body. The wind guiding component includes an upper mounting plate and a lower mounting plate that are circumferentially arranged on the inner wall of the tower body. A plurality of wind guiding plates are rotatably connected between the upper mounting plate and the lower mounting plate. The wind guiding plates are arranged in a ring shape, and adjacent wind guiding plates form a wind guiding channel.
[0007] Further, the wind guiding plate includes a connecting plate whose two ends are respectively rotatably connected to the upper mounting plate and the lower mounting plate, and an arc plate is connected to the end of the connecting plate.
[0008] Further, the arc plates on each wind guiding plate have the same orientation.
[0009] Further, the upper ends of the connecting plate and the arc plate are both arc-shaped.
[0010] Further, upper diversion plates and lower diversion plates are respectively installed on the outer surface of the tower body. The upper diversion plates and the lower diversion plates are both arranged in a ring shape, and are respectively arranged on the upper side and the lower side of the air inlet. The upper diversion plates and the lower diversion plates form an air diversion opening.
[0011] Furthermore, the cross-sections of the upper air guide plate and the lower air guide plate are rectangular or arc-shaped.
[0012] In the above technical solution, the beneficial effects of a countercurrent energy-saving natural ventilation cooling tower provided by the present utility model are as follows:
[0013] Through the provided air guiding assembly, when the outside air flows from outside the tower to inside the tower through the air guiding channel, under the action of the air guiding plate, the outside air changes from the original direct linear movement towards the middle of the tower body to a rotational movement gradually approaching the middle, and under the action of the pressure difference inside the tower, it moves upward. On the one hand, it prolongs the retention time of the air inside the tower, thereby making full use of the outside air for heat exchange; on the other hand, it changes the air distribution at the bottom of the tower. Compared with the traditional direct movement towards the middle, it avoids the reduction of the air flow velocity caused by the contact of air from all directions, thereby improving the heat exchange effect.
[0014] It should be understood that the foregoing general description and the following detailed description are both exemplary and explanatory and are not intended to limit the present disclosure.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.
[0022] Please refer to Figure 1-2 , a countercurrent energy-saving natural ventilation cooling tower, comprising a tower body 1. An air inlet 11 is provided at the lower side of the tower body 1. A wind guiding assembly is installed inside the tower body 1. The wind guiding assembly includes an upper mounting plate 21 and a lower mounting plate 22 that are circumferentially arranged on the inner wall of the tower body 1. A plurality of wind guiding plates 23 are rotatably connected between the upper mounting plate 21 and the lower mounting plate 22. The wind guiding plates 23 are arranged in a ring shape, and adjacent wind guiding plates 23 form a wind guiding channel 24.
[0023] Through the provided wind guiding assembly, when the outside wind flows from outside the tower to inside the tower through the wind guiding channel 24, under the action of the wind guiding plates 23, the outside wind changes from the original direct linear movement towards the middle of the tower body 1 to a rotational movement gradually approaching the middle, and under the action of the pressure difference inside the tower, it moves upward. On the one hand, it prolongs the retention time of the air inside the tower, thereby making full use of the outside wind for heat exchange; on the other hand, it changes the air distribution at the bottom of the tower. Compared with the traditional direct movement towards the middle, it avoids the reduction of the air flow velocity caused by the contact of air from all directions, thereby improving the heat exchange effect.
[0024] Further, the wind guiding plate 23 includes a connecting plate 230 whose two ends are respectively rotatably connected to the upper mounting plate 21 and the lower mounting plate 22. An arc-shaped plate 231 is connected to the end of the connecting plate 230. The arc-shaped plate 231 can guide the outside wind to make a rotational movement approaching the middle component.
[0025] Further, the arc-shaped plates 231 on each of the wind guiding plates 23 have the same orientation. Thus, it avoids the reduction of speed caused by the contact of winds in different directions.
[0026] Further, the upper ends of the connecting plate 230 and the arc-shaped plate 231 are both arc-shaped. Thus, the cooling water falling on the upper ends of the connecting plate 230 and the arc-shaped plate 231 can fall to the bottom of the tower body 1, improving the water circulation utilization rate.
[0027] Furthermore, an upper air deflector 31 and a lower air deflector 32 are respectively installed on the outer surface of the tower body 1. Both the upper air deflector 31 and the lower air deflector 32 are annularly arranged and are respectively disposed on the upper side and the lower side of the air inlet 11. The upper air deflector 31 and the lower air deflector 32 form an air guiding opening 33. When there is wind outside, the air guiding opening 33 can guide more vertically-directed wind into the tower, improving the utilization rate of natural wind.
[0028] Furthermore, the cross-section of the upper air deflector 31 and the lower air deflector 32 is rectangular or arc-shaped.
[0029] Working principle: When the outside wind flows from outside the tower to inside the tower through the air guiding channel 24, under the action of the arc-shaped plate 231 of the air deflector 23, the original straight-line movement directly towards the middle of the tower body 1 is changed into a rotational movement gradually approaching the middle, and under the action of the pressure difference inside the tower, it moves upward. On the one hand, it prolongs the retention time of the air inside the tower, thereby making full use of the outside wind for heat exchange; on the other hand, it changes the air distribution at the bottom of the tower. Compared with the traditional direct movement towards the middle, it avoids the reduction of the air flow velocity caused by the contact of air from all directions, thereby improving the heat exchange effect.
[0030] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
