High-efficiency heat exchange type cooling circulating water system and working method thereof

Abstract

The invention discloses a high-efficiency heat exchange type cooling circulating water system. The high-efficiency heat exchange type cooling circulating water system involves a cooling tower, a cooling fan, a water collecting tank, a circulating water pump, a water supplying pipe, a condenser and an auxiliary cooler, wherein the cooling fan is arranged at the top of the cooling tower, the water collecting tank is arranged at the bottom of the cooling tower, the circulating water pump is connected to the water collecting tank , the water supplying pipe is arranged at the output end of the circulating water pump, the water supplying pipe is connected with the cooling tower, the condenser is arranged on the water supplying pipe, and the auxiliary cooler is arranged on the condenser. On one hand, the cooling tower is improved, the evaporation of heat is improved, and meanwhile, an additional cooling structure is additionally arranged, higher cooling capacity can be provided according to the actual temperature, and the cooling speed of the equipment is further increased; and on the other hand, the air purifying capacity is improved, the pollution of air to circulating water is reduced,the number of suspended matter in the water is reduced, the cooling effect of the equipment is improved, and the quality and the practicability of the equipment are improved.

Description

technical field [0001] The invention belongs to the field of circulating water systems, in particular to a high-efficiency heat exchange cooling circulating water system and its working method. Background technique [0002] The function of the circulating water system is to send cooling water (sea water) to the high and low pressure condensers to cool the exhaust steam of the low pressure cylinder of the steam turbine, so as to maintain the vacuum of the high and low pressure condensers, so that the circulation of steam and water can continue. In addition, it supplies water to the open water system and the ash flushing system. At present, the circulating water system has been developed to a relatively high level. Because the country attaches great importance to energy conservation, emission reduction and environmental protection, industrial sewage treatment is a rigid condition for enterprise investment and construction, which makes the demand for industrial sewage treatment...

AI Technical Summary

Problems solved by technology

[0005] 1. Most of the current circulating water systems have problems of low efficiency, slow cooling speed, high minimum cooling temperature that can be achieved, and poor equipment practicability

[0006] 2. Most of the current circulating water systems do not have the ability to purify air. Suspended solids are likely to be generated during the cooling process, resulting in poor water quality, weakened equipment cooling effect, and poor equipment quality.
