The ultrahigh-temperature heat-insulation device has the advantages of being simple in structure, mainly applicable to effective heat preservation when the surface of the thermal device or the surface of the pipeline is in the ultra-temperature state with the temperature of more than 650DEG C, and the like.

Description

technical field [0001] The invention relates to an ultra-high temperature heat insulation device mainly used for pipelines or equipment, and belongs to the technical field of heat preservation. Background technique [0002] In order to save energy and reduce energy consumption, some thermal insulation measures are taken for some thermal equipment and thermal fluid transportation pipelines, and thermal insulation materials are used on the surface or pipeline of thermal equipment to reduce the heat dissipation and achieve the purpose of energy saving. However, the above-mentioned thermal insulation measures are basically applicable to ordinary high-temperature equipment and high-temperature pipelines. The surface temperature of thermal equipment and pipelines exceeds what people call high temperatures, such as 100-200°C; but for temperatures of 300°C or even 600°C , it can be said to be ultra-high temperature. At this time, it is basically not suitable to use conventio...

Problems solved by technology

However, the above-mentioned thermal insulation measures are basically applicable to ordinary high-temperature equipment and high-temperature pipelines. The surface temperature of thermal equipment and pipelines exceeds what people call high temperatures, such as 100-200°C; but for temperatures of 300°C or even 600°C , it can be said to be ultra-high temperature. At this time, it is basically not suitable to use conventional fiber insulation materials for insulation, because the ultra-high temperature will burn these fiber insulation materials. It will also turn red under high temperature conditions. Therefore, under ultra-high temperature conditions, conventional inorganic or organic fiber insulation materials or vacuum or thickened material thickness cannot play a good insulation effect
