Due to the continuous advancement of industrial technology, the cover of the sewage tank has evolved from the traditional capping method to the cover of the membrane structure. A membrane structure is added above the sewage tank. At this time, the waste gas generated in the sewage tank is isolated from the air and is on the surface of the protective cover. Add an air outlet and install a ventilation pipe. The exhaust gas enters the exhaust gas purification tower from the ventilation pipe. In order to increase the collection of exhaust gas, a glass fiber reinforced plastic fan is installed in front of the purification tower. The exhaust gas is sucked into the purification tower by the fan, and the exhaust gas is sprayed in two stages in the tower. If the exhaust gas is acidic, it will be absorbed by lye circulation. If the exhaust gas is alkaline, it will be absorbed by acid circulation spraying. The exhaust gas treatment efficiency is over 90%, and the emission reaches the relevant national standards.
The steel supporting anti-hanging membrane structure uses a membrane material with strong corrosion resistance to cover the exhaust gas, and the steel structure hangs the membrane outside, which not only exerts the corrosion resistance of the membrane material, but also fundamentally solves the problem of the steel structure. Corrosion problems caused by contact with corrosive gases. Therefore, the steel structure can be designed according to the anti-corrosion grade of ordinary building steel structure, with a service life of 50 years, giving play to the performance of the steel structure, and realizing the perfect combination of structural framework and covering materials.
