It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] Embodiment 1, as Figure 1 As shown, a novel circulating water auxiliary cooling pipeline includes a water tank 1, which is used to store cooling water and condensed water of water vapor to maintain the normal operation of the cooling system. A fan 4 is arranged on the top of the water tank 1, and the fan 4 generates air flow through the rotation of the fan blades of the fan 4 to force evaporation, so as to promote the rapid dissipation of water vapor and reduce the water temperature of the cooling water in the water tank 1. A water diversion pipe 5 is arranged at the bottom of the water tank 1, and the water diversion pipe 5 draws cooling water from the water tank 1 for circulating cooling. A water diversion pump 6 is arranged on the water diversion pipe 5, and the water diversion pump 6 is used to provide power to accelerate the flow of cooling water.

[0021] The water supply pipe 5 is connected to the water-using equipment 8, which receives cooling water for cooling to ensure its normal operation. The water-using equipment 8 is connected back to the water storage tank 1 through the return pipe 10, and the cooling water passing through the water-using equipment 8 is sent back to the water storage tank 1 through the return pipe 10 for recycling.

[0022] An outlet pipe 11 is provided on the water inlet pipe 5. The outlet pipe 11 leads out the cooling water in the water inlet pipe 5. The outlet pipe 11 is connected to a cooling water pan 13. The cooling water pan 13 has a large surface area and can accommodate cooling water. The cooling water pan 13 is arranged above the fan 4. The cooling water pan 13 realizes rapid cooling and condensation of the water vapor rising by the fan 4 through surface heat exchange. The condensed water falls from the cooling water pan 13 into the water storage tank 1 for reuse. The cooling water pan 13 is connected to the return pipe 10 through a connecting pipe 15. The cooling water in the cooling water pan 13 is sent to the return pipe 10 through the connecting pipe 15 after heat exchange and then returns to the water storage tank 1.

[0023] The following is a detailed description of the design of the above key components:

[0024] The top of the water tank 1 is provided with a water supply pipe 2, and a water supply valve 3 is provided on the water supply pipe 2. The water supply pipe 2 ensures the stability of the water level of the water tank 1. When the water level in the water tank 1 is low, new water can be added to the water tank 1 through the water supply pipe 2. The water supply valve 3 can control the opening and closing of the water supply pipe 2 to control the flow rate of the water supply, so that the water level is kept within an appropriate range.

[0025] A number of fans 4 are arranged horizontally on the top of the water storage tank 1. The cooling efficiency is improved by using multiple fans 4, the evaporation rate of water vapor is increased, and the water temperature is reduced.

[0026] There are a number of water diversion pipes 5, and the number of water diversion pumps 6 corresponds to the number of water diversion pipes 5. Multiple water diversion pipes 5 are converged into one and connected outward. Multiple water diversion pipes 5 speed up the outflow of cooling water. Multiple water diversion pipes 5 are converged into one and connected outward, and then can be divided and connected according to the number of water-using equipment 8 to ensure that it can be effectively delivered to each water-using equipment 8.

[0027] The water-using equipment 8 is provided with an electric control valve 9 on the water diversion pipe 5 at both sides. The setting of the electric control valve 9 can realize the precise control of the cooling water flow, adjust the flow rate and flow velocity of the cooling water inflow and outflow as needed, and ensure that the cooling effect of the water-using equipment 8 reaches the best state.

[0028] The outlet pipe 11 is provided with an outlet valve 12, and a connecting valve 14 is provided on the outlet pipe 11 at the front side of the cooling water tray 13. The outlet valve 12 can control the outflow of water from the outlet pipe 11. The setting of the connecting valve 14 can conveniently control the flow rate of cooling water entering the cooling water tray 13.

[0029] Water diversion valves 7 are provided on the water diversion pipe 5 at both sides of the water diversion pump 6. The setting of the water diversion valve 7 can adjust the working state and flow rate of the water diversion pump 6, so as to make the delivery of cooling water more accurate and effective, and ensure the normal operation of the cooling system.

[0030] Example 2, as described in Example 1, a new type of circulating water auxiliary cooling pipeline, the temperature of the low-temperature circulating water rises after cooling the equipment. When cooling through the fan 4, a large amount of high-temperature water vapor is forced to evaporate by the airflow of the rotating blades of the fan 4, causing the water level of the water storage tank 1 to drop, and a large amount of new water needs to be added. The water vapor evaporated from the fan 4 contains various drugs such as scale inhibitors and preservatives, and the evaporation of water also causes the loss of drugs.

[0031] In order to reduce the loss of water vapor, a cooling water pan 13 is placed above the fan 4. The cooling water pan 13 is round or square. Low-temperature water is passed into the cooling water pan 13. The evaporated water vapor naturally flows upward and encounters the cooling water pan 13. After condensation occurs through surface heat exchange, the condensed water naturally falls into the water storage tank 1, completing partial recovery of evaporated water vapor. The outlet water temperature of the cooling water pan 13 increases after heat exchange with water vapor, and is merged into the return pipe 10 again, and enters the water storage tank 1 together to complete normal heat exchange. The cooling water pan 13 completes the heat exchange recovery process.

[0032] The center point of the cooling water pan 13 should be consistent with the center point of the fan 4, so as to achieve the maximum contact area for water vapor evaporation. The cooling water pan 13 needs to be kept a distance above the highest point of the fan 4. If the distance is too high, the steam will be affected by the wind and deviate, and the area of ​​water vapor contacting the cooling water pan 13 will be reduced, resulting in poor recovery effect. If the distance is too low, steam evaporation will be blocked, the steam circulation speed will decrease, and the cooling effect will be poor.

[0033] At present, if the two fans 4 run uninterruptedly for 24 hours, the pool needs to be replenished with 200 tons of new water per hour. After the cooling water pan 13 connecting valve 14 is opened, low-temperature circulating water is introduced into the cooling water pan 13, and the water vapor evaporating upwards falls into the pool after heat exchange and condensation with the cooling water pan 13. Under the condition that the replenishment amount remains unchanged, the water level of the pool rises. At this time, the replenishment valve 3 of the water storage tank 1 can be closed, and the replenishment amount of the pool per hour is reduced from the original 200 tons to 150 tons, and 50 tons of circulating water can be recycled per hour.
