Dry-wet combined industrial circulating water cooling system

Abstract

The invention relates to a dry-wet combined industrial circulating water cooling system, which is mainly applied to an industrial circulating water cooling process in the industries of chemical industry, metallurgy and the like. The dry-wet combined industrial circulating water cooling system comprises a dry cooling tower (1), a closed wet cooling tower (2), a water inlet main pipe (3), a water return main pipe (4), a bypass pipe (5), a valve (6) and cooled equipment, wherein the dry cooling tower (1) comprises a dry cooling tower body (1-2) and an air cooling radiator (1-1); the closed wet cooling tower (2) comprises a wet cooling tower body (2-3), a cooling fan (2-1), a cooling water pipeline (2-4), a cooling water nozzle (2-2) and a cooling coil (2-5); the dry cooling tower (1) and theclosed wet cooling tower (2) are arranged in series; and a pipeline through which industrial circulating water is discharged out of the dry cooling tower (1) and enters the closed wet cooling tower (2) is provided with the bypass pipe (5) which is communicated with the water return main pipe (4). According to the industrial circulating water cooling system, the water consumption is lowered, the water resource is saved, the temperature of circulating water can be lowered, and higher requirements are met.

Description

technical field [0001] The invention relates to an industrial circulating water cooling system. It is mainly used in the cooling process of industrial circulating water in chemical industry, metallurgy, building materials, coking, electric power and other industries. Background technique [0002] Factories and enterprises will generate a lot of heat during the production process, and part of the heat will be discharged through the industrial circulating water cooling system. [0003] The most common industrial circulating water cooling system is a wet circulating water cooling system, which is cooled by a wet cooling tower. There are two types of wet cooling towers: open type and closed type. The cooling process requires water evaporation and consumes a lot of water. Therefore, the application of wet circulating water cooling systems in water-scarce areas is limited. [0004] Another cooling method that can be used for industrial circulating water is air cooling, that is,...

AI Technical Summary

Problems solved by technology

The advantage of the dry cooling system is that it consumes very little water. However, due to the influence of the ambient temperature outside the tower, when the ambient temperature is high in summer, the outlet temperature of the circulating water is high, which often cannot meet the requirements of industrial production.

Therefore, the system has not been widely used
