Description

Technical Field

[0001] The invention belongs to the engineering field and relates to a thermal insulation structure, in particular to a modular curved thermal insulation layer frame. Background Art

[0002] Insulation and heat insulation are one of the basic industrial technologies. The application of efficient insulation technology is crucial for energy-intensive industries and is one of the key factors for the sustainable development of the industry. The application of efficient insulation technology can effectively reduce the operating costs of industrial facilities or equipment and accumulate considerable economic benefits in long-term operation; at the same time, reducing energy consumption can reduce greenhouse gas emissions, thereby achieving huge social benefits. After entering the 21st century, modular technology has become one of the technical foundations for major engineering construction. Off-site pre-installation of modules and precise installation of modules on site can effectively improve construction efficiency, achieve safety, quality assurance and cost goals, and minimize environmental impact.
