Title:
HIGH-TEMPERATURE-RESISTANT SMOKE PROTECTION AND EXHAUST DUCT USING AEROGEL
Document Type and Number:
WIPO Patent Application WO/2023/201690
Kind Code:
A1
Abstract:
The present invention relates to the technical field of fire-fighting smoke exhaust. Provided is a technical solution. During the process of installing a high-temperature-resistant smoke protection and exhaust duct, since a heat insulation layer needs to be tightly connected, the installation efficiency is reduced. Provided in the present invention is a technical solution, in which a smoke protection and exhaust duct structure that can be quickly connected and fixed and has a heat insulation function is provided. A rapid connection between smoke protection and exhaust ducts is realized, and the working efficiency is improved; in addition, it is guaranteed that the tightness and fire resistance of the smoke protection and exhaust ducts are not reduced, the practicability is high, and the problems in the background art can be effectively solved.
