[0018] To address the technical problem of microbial growth in cooling water within novel cooling towers, this invention provides a novel cooling tower capable of killing microorganisms in the cooling water and inhibiting their reproduction.

[0019] Please see Figure 1 , Figure 1 This is a structural schematic diagram of the novel cooling tower provided in this embodiment of the utility model. The novel cooling tower includes a ventilation duct 1, a circulation unit 2, and an ultraviolet germicidal lamp 3.

[0020] A cooling chamber is formed inside the air duct 1. The circulation unit 2 includes a water distribution pipe 21 and a water pump 22. The lower end of the water distribution pipe 21 connects to the bottom of the cooling chamber, and the upper end of the water distribution pipe 21 extends to the upper part of the cooling chamber. The inner wall of the water distribution pipe 21 is coated with an antibacterial agent, which can kill microorganisms in the water. The water pump 22 is connected to the water distribution pipe 21 and drives the cooling water to flow from the lower end to the upper end of the water distribution pipe 21. An ultraviolet germicidal lamp 3 is installed in the cooling chamber to disinfect and sterilize the cooling water.

[0021] In some embodiments, an air inlet 11 communicating with the cooling chamber is formed on the side of the air duct 1, and an air outlet 12 communicating with the cooling chamber is formed on the top surface of the air duct. Cooling airflow flows in from the air inlet 11 and flows out from the air outlet 12, cooling the cooling water in the cooling chamber.

[0022] The ventilation duct 1 is preferably made of advanced composite material SMC (compression molding) molding process, which has high strength, good rigidity, and vibration resistance that is significantly better than conventional products. The ventilation duct 1 has low resistance and low operating energy consumption. In addition, the inner wall surface has good smoothness and strong aging resistance.

[0023] In some embodiments, the antibacterial agent coated inside the water distribution pipe 21 is a nano silver ion antibacterial agent.

[0024] In some embodiments, the circulation unit 2 further includes multiple nozzles 23, with the upper end of the water distribution pipe 21 connected to each nozzle 23, and the nozzles 23 arranged downwards. The nozzles 23 are preferably IN-type uniform splash nozzles, made of reinforced ABS material, with a normal operating pressure ≥0.6mH2O, which have the advantages of uniform water distribution, no hollow areas, anti-clogging, and anti-loosening; the nozzles and water distribution pipes are connected by threads for easy installation and replacement.

[0025] In some embodiments, the ultraviolet germicidal lamp 3 is located below the air inlet 12.

[0026] In some embodiments, the novel cooling tower further includes a fan 4 disposed at the air outlet 12, with the upper end of the water distribution pipe 21 and the nozzle 23 located below the fan 4. The fan 4 is preferably a dedicated axial flow fan, and the impeller of the fan undergoes a static balance test before leaving the factory, with the rigid rotor balance accuracy of the test being G5.6.

[0027] The blades of fan 4 are made of reinforced fiberglass through molding, featuring a high-efficiency airfoil structure. The blade angle is adjustable, and during commissioning and production, the blade angle is set to the highest efficiency setting. The fan blades are molded in one piece, and the windward side of the blades is equipped with polyurethane anti-erosion leading edge blades.

[0028] The fan 4 adopts a double-clamp hub, and the hub material is a new composite material of SS316L+2205. The transmission shaft of the fan 4 adopts a carbon fiber transmission shaft, and the coupling material is SS316. A flying shaft limiting device is additionally provided. The fan 4 has a reverse rotation function to utilize the hot air inside the tower and eliminate the ice curtain at the air inlet.

[0029] The design safety factor of the reducer matched with the fan 4 is 2.0. The reducer is equipped with one non-contact shaft vibration probe, one temperature probe and one oil level probe (signals are introduced into the DCS system) and an oil gauge outside the air duct 1, so as to ensure the reliable operation of the fan. Remote oil filling can be realized for the reducer outside the air duct 1.

[0030] The reducer is required to adopt two-stage gear transmission, the gear material is high-quality alloy steel, and is subjected to process treatments such as carburizing, quenching and gear grinding. The reducer is equipped with a three-parameter probe (for vibration, oil temperature and oil level), special cables and an on-site junction box (arranged outside the air duct 1), instrument signals are connected to the junction box, and 4-20mA signals are output to the DCS.

[0031] In some embodiments, the novel cooling tower further comprises a water eliminator 5 arranged in the cooling cavity, the water eliminator is provided with a plurality of curved through holes, the water eliminator 5 is located below the fan 4 and above the water distribution pipe 21. The water eliminator 5 captures and recovers water droplets rising with airflow by means of inertial collision, so as to reduce the drift loss of cooling water.

[0032] In a preferred embodiment, SJ160-40 high-efficiency low-resistance reinforced arc-shaped water eliminator is adopted. The water eliminator sheet is made of flame-retardant modified PVC Class A new material and formed by extrusion drawing. The flame-retardant oxygen index is greater than 30.

[0033] In some embodiments, the novel cooling tower further comprises a packing part 6 arranged in the cooling cavity, and the packing part 6 is located below the upper end of the water distribution pipe 21. The spray head 23 is arranged toward the packing part 6.

[0034] The packing part 6 preferably adopts IC-C type film packing, which is formed by hot pressing. It adopts a three-dimensional corrugated structure, and forms multi-directional flow channels through the staggered corrugation design, which increases the water film area and the contact time between water and air, improves the heat exchange efficiency by 20%-30%, and reduces the pressure drop by 15%. Gradient porosity design: the porosity of the packing layer gradually decreases from top to bottom, which matches the gravity distribution of water flow, reduces "dry zones" and "dead zones", and makes the water distribution uniformity reach more than 95%, avoiding local scaling. Nano-scale hydrophilic material (such as titanium dioxide) is sprayed on the surface of the packing, which reduces the surface tension of the water film, accelerates the formation speed of the water film, and improves the evaporation efficiency by 10%-15%.

[0035] In some embodiments, the novel cooling tower further comprises a water injection pipe 7 communicating with the bottom of the cooling cavity, and the main water pipe 7 is used for supplementing the consumed cooling water.

[0036] In some embodiments, the novel cooling tower further includes a baffle plate 8 disposed above the air inlet 11. The upper end of the baffle plate 8 is connected to the inner wall of the air duct 1, and its lower end extends inward to prevent cooling water from drifting out of the air inlet 11.

[0037] To better understand this utility model, the following is combined with... Figure 1 The technical solution of this utility model is described in detail below: Water pump 22 draws cooling water from the bottom of the cooling chamber and sprays it onto the packing section 6 through nozzle 23. Fan 4 drives external air to flow in through air inlet 11 and out through air outlet 12. As the cooling water flows through the packing section 6, air also passes through the packing section 6, carrying away the heat from the cooling water. At the same time, some of the cooling water evaporates, also carrying away heat and lowering the temperature of the remaining cooling water. The evaporated cooling water is blocked by water collector 5, turns back into liquid, and flows back to the bottom of the cooling chamber.

[0038] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
