Circulating cooling water system and cooling water circulation method thereof

Abstract

The invention discloses a circulating cooling water system and a cooling water circulation method using the same. The system comprises a cooling device which is connected with a workshop appliance to form a circulating loop. The cooling device comprises a cooling tower, a circulating cooling water supply pool and a mixer which are sequentially connected, wherein the circulating cooling water supply pool is connected with the mixer through at least two pipelines connected in parallel; one pipeline is directly connected with the mixer; the other pipeline is connected with the mixer through a heat exchanger; each pipeline is provided with an adjusting valve. Only a little cooling water is subjected to heat exchange and cooling through the heat exchanger, the number of refrigerators for providing chilled water to the heat exchanger is reduced indirectly, and the operation expenses are greatly reduced. Meanwhile, by the adoption of the circulating cooling water system and the cooling water circulation method using the same, cooling water of the refrigerators can be from the circulating cooling water supply pool for providing cooling water to the workshop appliance, the number of water supply pools and the number of corresponding water supply pumps are reduced, and therefore the technological requirements are met, the purpose of energy conservation is also achieved, and the water temperature control precision is improved.

Description

technical field [0001] The invention relates to the field of circulating cooling, in particular to a circulating cooling water system and a cooling water circulating method. Background technique [0002] In the process of industrial production, such as the production process of rubber tire enterprises, workshop equipment needs a large amount of cooling water. In order to ensure the temperature and flow of cooling water, a circulating cooling water system needs to be configured, usually using a closed circulating cooling water system. This design has disadvantages Large investment and high energy consumption. [0003] The circulating cooling water system generally adopted in the prior art is as figure 2 As shown, the closed circulation cooling water system is adopted. The closed circulation cooling water system completely adopts heat exchanger for indirect heat exchange. The specific working process is (the temperature value is an example, not applicable to all closed-loop...

AI Technical Summary

Problems solved by technology

The system requires large investment and high energy consumption

The water temperature control accuracy is not high, and it cannot be adjusted in real time according to the water temperature, and the error is relatively large. For example, the water temperature is different during the day and at night.
