How to Install Silica Aerogel Insulation Blanket in Vaporization Furnace
Silica aerogel blanket, also known as "blue smoke" and "solid smoke", is the lightest solid material known at present, and it is also a material with good thermal insulation properties so far. Because of its nanoporous structure (1~) 100nm), low density (3~250kg/m3), low dielectric constant (1.1~2.5), low thermal conductivity (0.013~0.025W/(mk)), high porosity (80~99.8%), high specific surface area (500~1000m2/g) and other characteristics.
The project is in-situ insulation in the gasification furnace, and the construction is carried out on the inner wall of the vessel according to the construction plan and requirements provided by the construction unit. Precautions before construction:
1. Insulation construction can only be carried out after the pressure strength test, tightness test and anti-corrosion engineering of the equipment to be constructed.
2. When welding the fixing parts of the insulation layer on the anti-corrosion and lining industrial equipment and pipelines, the welding and post-weld heat treatment must be carried out before the anti-corrosion, lining and pressure test.
3. Ensure that all surfaces and equipment that require insulation are clean and dry.
4. Before the construction of the adiabatic project, the quality of the aerogel insulation blanket and its products should be checked to ensure that the aerogel insulation blanket and its products are clean, dry and have good thermal insulation properties.
5. The construction personnel of the thermal insulation project should be equipped with perfect labor protection supplies.
6. The construction site should be equipped with temporary water supply, power supply and other facilities. The road should be smooth and there should be suitable processing sites. The construction machinery should be matched properly.
Security
1. Construction workers must wear gas masks, dust caps and gloves (if you have a conditional wearable overalls) and wear eye masks.
2. When the construction is completed or comes to an end, the tools and venues should be cleaned up.
3. It should ensure good ventilation in the tank and prevent the construction workers from suffocating due to lack of oxygen in the tank. There must be no objects or facilities in the tank that affect safety and there are qualified lighting measures.
The construction is carried out by double-layer aerogel blanket insulation. The joints are tight, the surface is flat, there is no bubbling in the same layer, and the inner and outer lamination seams ensure the heat preservation effect.
Workplace division
1. For the insulation construction to be carried out efficiently, we recommend setting a separate cutting area. The aerogel insulation blanket is cut into the required dimensions for construction in the cutting area, and the cut size is convenient for construction.
2. The setting of the cutting area should pay attention to the following points: The cutting area should have some protective facilities to prevent material damage. The cutting area should be provided with a cutting table or cutting board of suitable length and width, and a bracket for placing the material should be prepared.
3. When cutting, apply a pipe of appropriate strength through the entire roll of aerogel insulation blanket and place it on the bracket. Then, the heat insulating material is laid on the cutting table in front of the bracket, and the tool is selected for cutting according to the size required for the construction.
4. The cut material is recommended to be wrapped or covered with plastic cloth for easy transportation to the construction area.
