Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection devices, in particular to a water quality detection device for a cooling circulating water system. Background Art

[0002] Circulating cooling water refers to the water that exchanges heat through a heat exchanger or direct contact heat exchange to exchange the heat of the medium and is cooled by a cooling tower and then recycled to save water resources. Water quality testing equipment is used to test water quality standards. In addition to physical and chemical indicators, there are also microbial indicators. For industrial water, whether it affects product quality or is easy to damage containers and pipes is considered.

[0003] When the existing water quality detection device for cooling circulating water system detects the water quality of cooling circulating water, it is often necessary to extract the cooling circulating water from the cooling tower, and then drip the cooling circulating water onto the detection device through a dropper for detection. The detection process is relatively cumbersome, and the cooling circulating water is easily affected by external factors during transportation, resulting in inaccurate inspection results of the cooling circulating water. In addition, after multiple inspections, impurities will be attached to the inner wall of the detection cylinder of the existing water quality detection device for cooling circulating water system, resulting in errors in the subsequent water quality inspection results due to the influence of impurities. For this reason, we propose a water quality detection device for cooling circulating water system. Utility Model Content
