DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 5 , the utility model provides a technical solution:

[0028] A ventilation device for a cooling tower, comprising a body 1, a vent 2 is provided on the top of the body 1, a tuyere pipe 3 is fixedly installed on the top of the vent 2, a first condensation component 4 is arranged inside the tuyere pipe 3, a ventilator 7 is fixedly installed inside the body 1, the first condensation component 4 comprises a mounting ring 41, the mounting ring 41 is fixedly installed on the inner wall of the tuyere pipe 3, a first mesh cover 42 is fixedly installed on the bottom of the mounting ring 41, the first mesh cover 42 is concave, and a guide column 5 is fixedly installed on the bottom of the first mesh cover 42 A second water condensation component 6 is provided at the bottom of the guide column 5, and the second water condensation component 6 includes a second mesh cover 61 fixedly connected to the bottom of the guide column 5, and a guide ring 62 is fixedly installed at the bottom of the second mesh cover 61. The outer wall and the inner wall of the guide ring 62 and the surface of the guide column 5 are provided with a guide groove 63. The second mesh cover 61 and the first mesh cover 42 are both made of aluminum metal. The second mesh cover 61 is convex, and the second mesh cover 61 and the first mesh cover 42 are hourglass-shaped and the area of ​​the second mesh cover 61 is larger than that of the first mesh cover 42.

[0029] By adopting the above technical solution, the main body 1 turns on the internal ventilator 7 when working to improve the ventilation in the main body 1. The ventilator 7 guides the water vapor in the main body 1 to the ventilating port 2 when working. When the water vapor passes through the second mesh cover 61 and the mounting ring 41, since the second mesh cover 61 and the mounting ring 41 are made of metal and the temperature is lower than the temperature of the water vapor, the water vapor contacts the second mesh cover 61 and the mounting ring 41 to produce a condensation effect, causing a large amount of water in the water vapor to be retained on the surfaces of the second mesh cover 61 and the mounting ring 41. As the amount of water retained on the surfaces of the second mesh cover 61 and the mounting ring 41 increases, and since the mounting ring 41 is concave, the amount of water increases and then flows out along the vent 2. The water flows toward the bottom along the mounting ring 41, and finally converges with the guide column 5, and then flows toward the second mesh cover 61 at the bottom through the guide column 5. When the water flows on the surface of the second mesh cover 61, since the second mesh cover 61 is convex, the water will flow to the bottom of the second mesh cover 61. While flowing, the water retained on the surface of the second mesh cover 61 will converge, and finally flow down through the guide ring 62 at the bottom of the second mesh cover 61. The surfaces of the guide column 5 and the second mesh cover 61 are also provided with guide grooves 63 to improve the efficiency of the downward flow of water. The design of the second mesh cover 61 and the mounting ring 41 greatly improves the ability of the fan 7 to recycle water resources when in use, thereby avoiding a large amount of water loss.

[0030] Specifically, Figures 1 to 3 As shown, a cooling component 8 is provided inside the air outlet pipe 3, and the cooling component 8 includes a heat-conducting ring 81, and the heat-conducting ring 81 is fixedly installed inside the air outlet pipe 3. A heat dissipation pipe 82 is fixedly installed on the outer surface of the air outlet pipe 3, and a heat dissipation fan 84 is movably installed inside the heat dissipation pipe 82. A dust-proof net 85 is fixedly installed on the side of the heat dissipation pipe 82 away from the air outlet pipe 3, and the heat dissipation fan 84 blows air toward the heat-conducting ring 81. An air outlet 83 is provided on the surface of the heat dissipation pipe 82 close to the heat-conducting ring 81. The heat-conducting ring 81 is made of heat-conducting material, and the inner wall of the heat-conducting ring 81 is in contact with the mounting ring 41, and the outer wall of the heat-conducting ring 81 is fixedly connected to the heat dissipation pipe 82.

[0031] By adopting the above technical scheme, the key point of the condensation effect caused by the contact between water vapor and the second mesh cover 61 and the mounting ring 41 lies in the temperature of the second mesh cover 61 and the mounting ring 41 themselves. If the temperature of the second mesh cover 61 and the mounting ring 41 increases after working for a long time, the hydrocondensation efficiency will be reduced. A heat-conducting ring 81 is installed inside the air outlet pipe 3. The heat-conducting ring 81 is made of a heat-conducting material and is in contact with the mounting ring 41. A heat dissipation structure composed of a heat dissipation pipe 82, a heat dissipation fan 84 and other components is installed on the surface of the air outlet pipe 3. The heat dissipation fan 84 blows air to the heat-conducting ring 81 to reduce the temperature of the heat-conducting ring 81. The wind blown by the heat dissipation fan 84 to the heat-conducting ring 81 can be discharged through the air outlet 83. After the temperature of the heat-conducting ring 81 is reduced, it is beneficial for the first mesh cover 42 to dissipate heat through the mounting ring 41, thereby ensuring the temperature of the first mesh cover 42 when working. The low temperature of the first mesh cover 42 itself is beneficial to the hydrocondensation effect, thereby ensuring the recovery of water resources by the device and further improving the water resource recovery capacity of the device.

[0032] Working principle: When the main body 1 is working, the internal fan 7 is turned on to improve the ventilation inside the main body 1, and the moisture in the water vapor is recovered through the second mesh cover 61 and the mounting ring 41 installed inside. The water condenses on the surface of the second mesh cover 61 and the mounting ring 41 and then flows downward. The setting of the first condensation component 4 and the second condensation component 6 greatly improves the water resource recovery capacity of the device. At the same time, a cooling component 8 is provided on the air outlet pipe 3. The cooling component 8 ensures the temperature of the mounting ring 41 itself when it is working, so as to avoid the problem of reduced condensation efficiency due to the increase of the temperature of the mounting ring 41 itself.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
