Description

Technical Field

[0001] The utility model relates to the technical field of chlor-alkali industry and is a circulating water pipeline high-pressure cleaning device. Background Art

[0002] At present, the domestic chlor-alkali industry generally uses circulating water as a cooling medium. Circulating water provides cooling capacity for the normal production of the device through heat exchange equipment such as surface condensers and plate heat exchangers. Circulating water is stored in a circulating water pool, transported to each device by a circulating water pump, and returned to the circulating water pool after passing through the heat exchange equipment of each device. The circulating water is cooled by the cooling fan above the circulating water pool. During the operation, the circulating water will exchange heat with different acids, alkalis, etc. At the same time, chemicals, acids or alkalis will be added to adjust the water quality of the circulating water.

[0003] Since the pH value of circulating water and indicators such as calcium, magnesium, and microorganisms in the water will fluctuate during operation, the return water temperature will rise after passing through the heat exchanger, which will cause scaling on the heat exchanger and return water pipeline, resulting in blockage of the heat exchanger and return water pipeline. If the return water pipeline is blocked during production, the production unit needs to be stopped to clean or replace the pipeline, which seriously affects the stable operation of the unit. Summary of the invention
