Description
Technical Field
The invention particularly relates to a cooling system and a cooling process of cooling water suitable for northern areas.
Background
The cooling water is used for carrying away the redundant heat generated in the operation of the equipment, so that the equipment can operate at a normal temperature. When the temperature of the equipment is lowered, heat is absorbed by the cooling water, so that the temperature of the cooling water is raised. The cooling water used circularly needs to transfer the absorbed heat, the temperature is recovered to the original value, and then the cooling water is used for cooling the heat-generating equipment, and the transfer of the temperature of the cooling water absorbing the heat is the cooling of the cooling water.
The cooling water is various, and the most common is circulating water. When the heating equipment has a clean requirement on the quality of the cooling water, the equipment needs to be cooled by an independent closed desalted water system, and then the desalted water is cooled by another cooling water with lower temperature, so that the redundant heat of the equipment is indirectly taken away. Because the running cost of the circulating water is low, the temperature of the circulating water on the water is close to the highest average temperature of the region in summer months, the temperature of the conventional circulating water on the water is 29 ℃, and the temperature of the return water is 39 ℃. Therefore, under the condition of meeting the temperature difference heat exchange condition, the circulating water is generally adopted to exchange heat and cool the desalted water, the running cost of the circulating water is lower, and the circulating water is widely used in the chemical field.
The circulating water is divided into a closed circulating system and an open circulating system. Open circulation systems are commonly used in industry due to their large footprint, high construction costs, and the like. The circulating water flows through the water flowing at the leaching tower and the fan to make the air flow and the water evaporate and take away the heat, so the open type circulating system has large water circulation amount and water evaporation loss.
And a large amount of water vapor at the top of the circulating water leaching tower is continuously evaporated into the air, the water-saving vapor has a large influence on the environment in winter in the north, and the research on the influence of the water vapor and the wind speed on the concentration of particulate matters in haze shows that ' the water vapor is positively correlated with the change of PM2.5/PM10 ', the water vapor rising corresponds to the GDS water vapor change and the PM2.5/PM10 mass concentration rising, and the water vapor falling corresponds to the PM2.5/PM10 mass concentration falling '. In order to ensure the environment, the using amount of circulating water is reduced in winter, the using amount of the circulating water is limited, and a high-cost cold medium is required to be used for ensuring the production operation.
In view of the above, the invention provides a cooling water cooling system and a cooling water cooling process suitable for northern areas, which can reduce the cost and improve the environmental quality while ensuring the cooling effect.
