Description

Technical Field

[0001] This utility model relates to the technical field of cooling water towers, and in particular to a cooling water tower. Background Technology

[0002] A cooling tower is a device that cools water. It utilizes the contact between water and air to dissipate waste heat generated in industrial processes or refrigeration and air conditioning systems through evaporation. Its basic working principle is as follows: dry (low enthalpy) air is drawn into the cooling tower through the air inlet by a fan; high-temperature water molecules with high saturated vapor pressure flow towards the low-pressure air, and hot, humid (high enthalpy) water is sprayed into the tower through the water distribution system. When the water droplets come into contact with the air, heat transfer occurs directly between the air and water, and the pressure difference between the water vapor surface and the air causes evaporation, carrying away heat from the water—this is evaporative heat transfer—thus achieving the purpose of cooling. A cooling tower generally consists of three parts: upper, middle, and lower. Its internal structure, from top to bottom, includes a fan (for mechanically ventilated counter-flow cooling towers), a water collector (or dewatering device), a water distribution system, water spray packing, air inlet windows, and a base (or water tank). In current cooling towers, when cooling water is being cooled, the fan draws air from the bottom of the cooling tower into the interior. The air carries away the heat after passing through the hot water and is then discharged from the top of the cooling tower. However, if the air is mixed with dust or other dirt when the fan draws air into the cooling tower, it can easily make the water inside the cooling tower dirty. Utility Model Content

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] This utility model discloses a cooling water tower, such as Figure 1-4 As shown, the system includes a tower body 1, with an air outlet at the top and an exhaust fan 2 fixedly mounted on the outlet. Multiple air inlets 11 are sealed at the bottom of the side wall of the tower body 1, spaced apart along the circumference of the tower body 1. When the exhaust fan 2 operates, it draws air into the tower body 1 through the air inlets 11 and then discharges it through the outlet. Simultaneously, the tower body 1 is equipped with a water inlet pipe and a water outlet pipe. A spray pipe is fixedly installed inside the tower body 1, with the water inlet pipe connected to a water pump. The spray pipe has multiple spray holes. The water pump pumps high-temperature water through the water inlet pipe into the spray pipe, which then sprays water through the spray holes. Air flowing over the high-temperature water dissipates the heat, and the water falls to the bottom of the tower body 1 and is discharged through the water outlet pipe. In addition, a packing layer is provided inside the tower body 1. The packing layer is located directly below the spray pipe. The packing layer is existing technology and will not be described in detail here. The packing layer has a large specific surface area. After the high-temperature water is sprayed down, it enters the packing layer, which can increase the contact area between the high-temperature water and the air, thereby enabling the airflow to better carry away heat and improve the heat dissipation efficiency.

[0023] In addition, a support net 31 is provided on the air inlet 11, and a fixing frame 3 is provided on the support net 31. The edge of the support net 31 is fixedly connected to the inner wall of the fixing frame 3. The fixing frame 3 is sealed to the air inlet 11. A fixing plate 33 is welded to the edge of the fixing frame 3. The fixing plate 33 is attached to the outer wall of the tower body 1, and bolts 331 are fixedly connected between the fixing plate 33 and the side wall of the tower body 1. The operator installs the fixing frame 3 into the air inlet 11, and then uses bolts 331 to thread the fixing plate 33 to the tower body 1, thereby fixing the fixing frame 3 to the tower body 1. In addition, a filter cloth 32 is provided on the support net 31. The filter cloth 32 is attached to the outer surface of the support net 31. The support net 31 supports and shapes the filter cloth 32. When the air is drawn into the tower body 1, it is filtered by the filter cloth 32, which can filter out dust and other dirt in the air, thus making it less likely to contaminate the water. In addition, an adhesive layer is provided between the edge of the filter cloth 32 and the carrier mesh 31, which bonds and fixes the filter cloth 32 and the carrier mesh 31 together. Furthermore, the carrier mesh 31 is wavy, which increases the area of ​​the filter cloth 32, thereby increasing the air intake efficiency. Meanwhile, a filter screen 34 is provided on the fixed frame 3, located on the surface of the filter cloth 32 facing away from the carrier mesh 31. The filter screen 34 can block some large-diameter particles and provides a certain degree of protection for the filter cloth 32. The filter screen 34 is threadedly connected to the fixed frame with a screw 341. The operator places the fixed frame 3 on it and then uses the screw 341 to fix the filter screen 34 and the fixed frame 3 together. The filter screen 34 is made of stainless steel, which is rust-resistant, corrosion-resistant, and has a long service life.

[0024] The implementation principle of a cooling water tower according to this utility model embodiment is as follows: When the exhaust fan 2 is working, it draws air into the tower body 1 from the air inlet 11. The water pump pumps high-temperature water into the spray pipe. The high-temperature water sprays down, and the air carries away the heat of the high-temperature water and then discharges it from the air outlet. When the air is drawn into the tower body 1, the filter screen 34 and the filter cloth 32 filter out dust particles and other dirt in the air, thereby preventing contamination of the water in the tower body 1.
