Description

Technical Field

[0001] The utility model relates to the technical field of water distribution pipelines in tank areas, and particularly to a temperature-controlled electric tracing structure for water distribution pipelines in tank areas. Background Technique

[0002] The intermediate tank area water distribution pipeline refers to various pipelines and their ancillary facilities used for distributing, transporting, and regulating water flow within the intermediate tank area or in systems associated therewith.

[0003] A small amount of water is contained in the feed components of the tanks in the intermediate tank area. To avoid water accumulation in the tanks, it is necessary to regularly separate water from the above-mentioned storage tanks. Since the steam tracing installed in the early stage has a high temperature, it is easy to cause vaporization of the materials in the water distribution pipeline, resulting in frequent cavitation of the water separation pump. To ensure normal water separation operation in winter, it is necessary to remove the steam tracing of the water distribution pipeline and replace it with temperature-controlled electric tracing. However, after the anti-freezing tracing is put into use in winter, the high tracing temperature is easy to cause vaporization of the materials in the water distribution pipeline, resulting in cavitation of the water separation pump and frequent damage to the water separation pump. Secondly, the steam tracing is prone to freezing and blocking, which is difficult to handle on-site and affects the normal water separation of the storage tank and the stable operation of the system.
