The environmental protection gas film is mainly used in coal mines or large and medium-sized power plant coal storage yards. The material of this product is environmentally friendly new materials and new processes. The main principle is to use the pressure difference between the inside and outside of the product to resist its own weight and wind and snow bearing capacity. The product adopts a fully enclosed structure, which allows workers and vehicles to enter and exit through the pressure relief door. The membrane material has a certain transparency, and the lighting effect in the environmental protection gas film is obvious. The construction of this structure is faster on site and the construction time is a steel structure. 1/3 of the construction cost is relatively economical and reasonable.
The general span of environmental protection gas film is 80-120 meters, and it is built on the retaining wall of 3-4 meters high. The height of the gas film is generally 20-36 meters. The inner space is relatively large, which can store a large amount of coal or raw materials. A 20-meter-long passage is required for vehicle entry and exit, and fast doors are placed on both sides of the passage. The vehicle is opened to the sensing range. The outer logistics door can be opened quickly. All vehicles enter the passage. The door at the outer end of the passage is closed and the inner logistics door is quickly opened to enter , The two doors must be interlocked.
