Description

Technical Field

[0001] This utility model relates to the field of cooling tower water replenishment technology, and in particular to a water replenishment device for a thermal power generation cooling tower. Background Technology

[0002] Cooling towers for thermal power plants are crucial pieces of equipment. Their main function is to reduce the temperature of cooling water through heat exchange between water and air, ensuring the normal operation of the generator set and extending the equipment's lifespan.

[0003] Utility model patent application publication number 202323042761.7 discloses a water replenishment device for a thermal power plant cooling tower, specifically relating to the field of cooling tower water replenishment technology. The device includes: a cooling tower with a water storage tank on one side, a transition water tank between the water storage tank and the cooling tower, and a first pumping mechanism between the water storage tank and the transition water tank; a controller with a first temperature sensor installed on the cooling tower and a second temperature sensor installed at the bottom front end of the transition water tank; a cold medium heat-conducting pipe; and a hot medium heat-conducting pipe. This utility model uses a transition water tank to transition the water replenished into the circulating water inside the cooling tower. Inside the transition water tank, the temperature of the replenished water is adjusted to the required temperature, ensuring that the temperature of the water after mixing with the circulating water is the same as the temperature of the water required for power generation. This results in a stable and suitable temperature of the water entering the power plant for power generation, leading to better power generation performance and strong overall practicality.

[0004] However, the above-mentioned devices still have some drawbacks in actual use. The most obvious one is that the circulating water is often lost during the operation of the cooling tower due to evaporation, periodic discharge, and splashing. Therefore, it is necessary to replenish the cooling tower water pool regularly to ensure the heat exchange efficiency of the cooling tower. Most existing cooling tower water replenishment devices replenish the cooling tower by setting up a water storage tank. However, due to the limited capacity of the water storage tank, it is not possible to effectively utilize the natural resource of rainwater for water replenishment. This results in the need to replenish the water regularly, which is time-consuming and labor-intensive. It requires manual supervision and water replenishment, causing inconvenience in use.

[0005] Therefore, it is necessary to invent a water supply device for thermal power generation cooling towers to solve the above problems. Utility Model Content

This effectively filters and purifies the collected rainwater, making the water cleaner and more convenient for subsequent use. This addresses the problem mentioned in the background art: circulating water in the cooling tower is often lost due to evaporation, periodic discharge, and splashing during operation, thus requiring regular replenishment of the cooling tower water tank to ensure the heat exchange efficiency of the cooling tower. Most existing cooling tower water replenishment devices use a water storage tank, but due to the limited capacity of the storage tank, it cannot effectively utilize the natural resource of rainwater for replenishment, resulting in the need for periodic refilling, which is time-consuming, labor-intensive, and requires manual supervision, causing inconvenience.
