Description

Technical Field

[0001] This utility model relates to the field of thermal pipeline equipment technology, and in particular to a thermal pipeline insulation and energy-saving device. Background Technology

[0002] Insulation of heating pipelines is intended to reduce heat loss from the pipelines, their accessories, and equipment to the surrounding environment. Its function is to reduce heat loss of the heating medium during transportation, save fuel, and ensure heating quality to meet user needs. With increasing environmental pollution, industrial wastewater and acid rain carrying chemicals are worsening soil contamination, leading to corrosion of water pipelines and subsequent ruptures and leaks.

[0003] Therefore, insulation devices are needed to insulate the heat pipes and avoid heat waste. Existing heat insulation and energy-saving devices are basically just a layer of insulation cotton or anti-corrosion layer attached to the surface of the heat pipes. The insulation effect on liquids is poor, resulting in a large amount of heat loss. At the same time, the outer insulation coating of the heat pipes cannot protect them and is easily damaged by external impact. Therefore, a heat insulation and energy-saving device for heat pipes is proposed. Utility Model Content
