Description

Technical Field

[0001] The utility model relates to the technical field of air cooling towers, in particular to an energy-saving air cooling tower. Background Art

[0002] An air-cooling tower uses water as a circulating coolant, absorbing heat from the system and releasing it into the atmosphere to lower the air temperature. The principle is that water and air flow in contact, exchanging heat to generate steam. The steam evaporates and removes heat, achieving evaporative, convective, and radiant heat transfer, thereby dissipating excess heat generated by industrial equipment and ensuring the normal operation of the system.

[0003] During the production process, due to the high temperature in summer, the cooling demand of the air-cooling tower increases, but the problem of insufficient cooling efficiency may occur. When the cooling efficiency of the air-cooling tower is insufficient, its outlet water temperature will rise, causing the outlet water temperature of the chiller to also increase. This will directly affect the stable operation and production efficiency of the equipment, and will also accelerate the wear of the equipment, shorten its service life, increase the failure rate of the equipment, and affect the continuity of the production line.

[0004] Furthermore, air-cooling towers consume significant amounts of coolant, leading to increased operating costs. This high coolant consumption requires frequent purchases and refills, increasing refill costs. Once coolant is insufficient, the equipment consumes more energy to maintain normal operation. This not only wastes energy but also increases operating costs. Utility Model Content

[0005] To solve the problem that the cooling efficiency of the current air cooling tower cannot meet the production requirements at high temperatures and the power consumption is too high;

[0006] The utility model provides an energy-saving air cooling tower. The air cooling tower is provided with an air inlet at the bottom and an air outlet at the top. The tower also includes a cooling water recovery device. A collecting box is provided on the inner wall of the air cooling tower to collect cooling water. A discharge pipe is provided in the collecting box to connect with the cooling water recovery device. A reflux pipe is provided at the bottom of the cooling water recovery device to connect with the upper part of the air cooling tower to recover cooling water after nitrogen cooling. The reflux pipe is provided with an ammonia cooling device and a chiller in parallel.

[0007] As a preferred solution, the air cooling tower is provided with a circulating water supply pipe to cool the air.

[0008] As a preferred solution, the cooling water recovery device is provided with a normal pressure nitrogen pipeline and a dirty nitrogen pipeline.

[0009] As a preferred solution, a low-temperature water pump is provided in the reflux pipeline, and the low-temperature water pump is provided between the cooling water recovery device and the ammonia cooling device.

[0010] As a preferred solution, the discharge pipe is provided with a three-way pipe connected to the cooling water input pipe.

[0011] As a preferred solution, a return water pipe is provided at the bottom of the air cooling tower to discharge the deposited cooling water.

[0012] As a preferred solution, a wire mesh demister is provided on the top of the cooling water recovery device to separate moisture from the air.

[0013] The beneficial effects of the utility model are:

[0014] 1. This utility model effectively improves the coolant supply efficiency of the air-cooling tower by adopting a parallel ammonia cooling device and chiller design, allowing the coolant to be more quickly and fully utilized in the heat exchange process, thereby significantly improving the cooling efficiency of the entire refrigeration system. Compared with traditional single cooling methods, this utility model not only ensures efficient cooling, but also enhances the stability and reliability of the system, making it suitable for various applications requiring high-efficiency cooling.

[0015] 2. This utility model effectively avoids energy waste by introducing a cooling water recycling mechanism. After completing a heat exchange, the cooling water is collected and reintroduced into the system for reuse, rather than being discharged directly. This measure not only significantly reduces water consumption but also reduces the additional costs associated with wastewater treatment. This not only reduces operating costs for businesses, but also aligns with current trends in sustainable development and brings significant economic benefits to the company.
