1. Safety
In the planning of gas film coal shed construction, safety guarantee is the most important. Safety accidents of steel structure grid coal shed often occur. The gas film coal shed is a type of structure supported by pressure equipment, which transmits air to a sealed indoor space and forms a large tension on the surface of the gas film. Even if there is a wind leak, it will not collapse. The upper layer of the air film building takes about 30 minutes from the road surface, about 2 meters from the road surface, and has sufficient time to ensure the evacuation of the staff in the shed. If the gas storage room is damaged or leaked, the system will immediately give an alarm and notify the maintenance personnel. And automatically control the fan to increase the amount of air supply to ensure the balance of the air pressure inside and outside the membrane structure until it is repaired.
2. Confined space
In the control of coal yard dust pollution, the traditional structure uses steel structure, but the steel structure is mainly used for the closure of small-span coal yard, and the construction time is long, even if it cannot meet the requirements of environmental protection related emission standards. The gas film coal shed has excellent sealing performance. The coal dust in the room is not easy to spread to the outside to prevent secondary pollution to the surrounding environment. The room is a positive pressure environment. Outdoor smoke and dust will not enter the room. The fully enclosed nature of the gas film coal shed greatly hinders the diffusion of coal dust.
3. Mid-to-late maintenance
Under a high-pollution environment, the structural members of the steel structure coal storage yard must be coated with anticorrosive paint for 3-5 years. After replacement for 5-7 years, the total maintenance cost should account for 1% of the original investment. The gas film coal shed is a kind of gas film material that is resistant to various types of strong acids, alkali corrosion, anti-aging, and zero maintenance for 25 years.
4. Construction period
Large-span coal shed, when the coal shed reaches tens of thousands of square meters, the completion time of the steel structure coal shed is 6-8 months, and the construction time of the gas film coal shed is not half of the construction time of the steel structure coal shed. It only takes two months from design conception, production to installation. There is no noise, no dust, and no construction waste in construction.
