Embodiment

[0035] Construct a circulating cooling water system of the present invention (its flow process sees figure 1 ), the water retention capacity of the circulating cooling water system is 100m 3 , circulation capacity (R) is 2000m 3 / h, and its supplementary water is urban water (tap water), and the concentration of water treatment agent (phosphorus system) in the system is set to 5.0mg / L (based on PO 4 3- count). According to the operation method described above (namely: install flow monitoring device A (Hangzhou Tellus UTG28 electromagnetic flowmeter) at the water replenishment end of the system, measure the replenishment water volume (M) of the system, and install a water quality indicator monitoring device (US meter) at the water replenishment end of the system Dunluo company DC4500 conductivity value controller), measure the conductivity of the make-up water, and transmit it to the online monitoring system C; and the (environment) temperature (T) measured online, the cooli...

Abstract

The invention relates to a circulating cooling water system and an operation method thereof. The circulating cooling water system provided by the invention is characterized in that a supplemented water quantity detection device is arranged between a water supplementing device and a cooling water circulator. By measuring the supplemented water quantity of the system, the addition quantity of a water treatment agent for maintaining the concentration of the water treatment agent in the system can be calculated. By using the circulating cooling water system and operation method provided by the invention, the difference between the actual concentration and set concentration of the water treatment agent in the circulating cooling water in the circulating cooling water system can be further reduced, thereby being beneficial to the stable and safe operation of the circulating cooling water system.

Description

technical field [0001] The invention relates to a circulating cooling water system and its operating method, in particular to a circulating cooling water system comprising an open cooling water circulating device and its operating method. Background technique [0002] The existing circulating cooling water system (especially the circulating cooling water system including the open cooling water circulation device) is prone to problems such as corrosion, fouling and bacterial growth. In this way, not only will the heat exchange efficiency be reduced, but also the equipment will be damaged. [0003] So far, the water quality monitoring of the circulating cooling water in the circulating cooling water system including the open cooling water circulation device is usually carried out (the circulating cooling water that does not meet the water quality requirements can be discharged from the system in time, and supplementary water can be added at the same time) and in the circulatin...
