The waste gas collection method of the anti-hanging film project:
1. Check the local environment. Due to the difference in climate between the north and the south, the climatic factor should be considered when covering the sewage tank. The corrosion resistance of the membrane material should be strong. It can improve its own oxidation resistance and extend the membrane material according to the difference of the external climate.
2. For the composition of exhaust gas, determine the use of membrane materials. The composition of waste gas pools in various industries is different, and the use of membrane materials is different. When the sewage tank is covered with a membrane, the composition of the waste gas in the tank must be considered, and the performance of the membrane material used can be determined to purify the waste gas.
3. According to the structure of the tank, determine the membrane structure. Before carrying out the capping operation on the pool body, a site survey should be done, and the structure of the capping can be determined according to the structure of the pool body. Common capping structures include steel frame membrane structure capping, tensile membrane structure capping and inflatable membrane structure capping.
Installation method of anti-hanging membrane project:
1. Ex-situ tension hoisting method
Membrane structure with rigid boundary shall be installed by pulling on the nearby ground/hoisting together with boundary members. The tensioning process of the ex-situ tensioning hoisting method is completed on the ground, which is convenient to operate/save time and effort. However, large-scale lifting equipment is required for hoisting, and corresponding working space is required.
2. Lifting in place and gradually tensioning method
After the anti-hanging membrane structure is hoisted in place on the membrane surface, the edge steel cables and membrane gusset plates are gradually stretched to apply pretension to the membrane surface.
3. Aerial assembly tensioning method
The supporting structure is picked out from the facade of a building, with a larger picking distance of 16 meters. Due to site conditions, if the structure is assembled into units, it cannot be lifted, so the aerial assembly/ aerial tensioning method is adopted.
