When installing a fiberglass gas collection cover above the sewage tank, the exhaust gas generated in the tank is isolated from the air. An exhaust outlet is added to the surface of the gas collection cover, and a ventilation pipeline is installed. The exhaust gas enters the exhaust gas purification tower through the ventilation pipeline. To enhance exhaust gas collection, a fiberglass fan is installed before the purification tower, which draws the exhaust gas into the tower. Inside the tower, the exhaust gas undergoes two-stage spraying. If the exhaust gas is acidic, an alkaline solution is used for cyclic absorption; if it is alkaline, an acidic solution is used for cyclic spraying and absorption. The exhaust gas treatment efficiency meets the relevant emission standards.

The fiberglass gas collection cover is made entirely of fiberglass, offering excellent characteristics such as corrosion resistance, flame retardancy, sturdiness, anti-slip properties, lightweight, easy installation, maintenance-free operation, and insulation.
1. Strong corrosion resistance: The product is made using acid and alkali-resistant, corrosion-resistant resin as the base material, with an excellent curing formula and process. Specific molds are used based on the shape and condition of each sewage tank for curing and molding.
2. Low cost and long service life: Compared to other sewage tank deodorization solutions, it has a lower cost, simple installation and construction, and a long service life.
3. Lightweight and high strength, easy installation: The fiberglass gas collection cover weighs only 1/3 to 1/4 of steel products, with a high degree of curing, high load-bearing capacity, and strength, making it suitable for large-span tanks. The cover can also be divided into several small sections for easy transportation and installation.
4. Aesthetic and aging-resistant: The product's surface is treated with aging-resistant, weather-resistant, and UV-resistant gel coat resin, making it smooth, aesthetically pleasing, and brightly colored.
5. Low operating and maintenance costs, easy inspection: Due to its high corrosion resistance and aging resistance, the product does not require regular maintenance like metal products, significantly reducing costs. Observation windows and inspection doors are預(yù)留 on the gas collection cover, allowing for easy maintenance without affecting normal equipment operation.
6. High design flexibility: The product size can be flexibly designed according to the specific conditions of the on-site tank, and shapes can include arched covers, circular covers, flat covers, etc.
