Cooling Method of Industrial Circulating Water
The cooling method of industrial circulating water is divided into direct cooling method and indirect cooling method. The cooling method of industrial circulating water is basically the same as that of ordinary circulating water, except that the flow rate is large, the temperature difference is large, and the internal composition is complex.
The cooling method of industrial circulating water is divided into direct cooling method and indirect cooling method. The cooling method of industrial circulating water is basically the same as that of ordinary circulating water, except that the flow rate is large, the temperature difference is large, and the internal composition is complex.
For example, iron and steel metallurgy, petrochemical industry and large machinery and equipment, often tens of thousands of cubic meters of flow, small also in hundreds of cubic meters of flow. Some cooling methods with injection flow are difficult to meet the process requirements, and only the corresponding production process is adopted.
1. direct cooling mode
It is sent to the open cooling tower, and the water pool is built at the bottom, which is sprayed downward through the top of the tower, and directly mixed with the air entering from the lower part to cool down. Open cooling tower has a round or square difference, power plants generally use tall hyperbolic cooling tower, but also this form of direct cooling. General bottom excavation pool, mainly for reserve and buffer use.
2. indirect cooling method
1, the introduction of air cooler, through the finned tube, by the high-speed sweep of a large number of air, convection heat transfer to the outside world. It is more suitable for use in areas with severe drought and water shortage, sufficient electricity and abundant land resources.
2. Introduce a closed cooling tower to absorb the latent heat of vaporization through the water film evaporation outside the tube bundle, and reduce the temperature of the circulating water in the tube bundle. This is the current use of more ways, economic analysis is feasible, reliable and stable operation, long life.
At present, the closed cooling tower is more in line with the long-term development of the enterprise cooling equipment.
