How to ensure the structural strength and anti-corrosion performance of FRP adsorption tank during long-term operation?

As a key equipment in the waste gas treatment system, the long-term operation stability of the FRP adsorption tank has a direct impact on the reliability of the entire environmental protection system. During use, the adsorption tank needs to face various corrosive gases, high humidity environments, and mechanical and thermal stresses caused by continuous operation.
In terms of the selection of raw materials, FRP adsorption tanks usually use resins with strong corrosion resistance as the base material, and combine with glass fiber to form a reinforced structure. Through scientific proportioning and lamination methods, the material itself has good compressive resistance and toughness, and can withstand the stress generated under negative or positive pressure. In addition, different types of corrosive gases have different tolerance to resins. Therefore, before the equipment is manufactured, suitable resin types are usually selected according to specific working conditions, such as resin systems with special properties such as acid resistance, alkali resistance, and solvent resistance, to further enhance the anti-corrosion effect.
Structural design also plays a key role in ensuring strength and anti-corrosion. The wall thickness, number of layers, fiber orientation, and end cover structure of the adsorption tank have all been mechanically calculated and simulated to ensure that no deformation or structural damage occurs during long-term load operation. At the same time, the internal structure design focuses on fluid uniformity and gas impact relief to avoid material wear caused by local airflow scouring. The tank body is often equipped with an inner lining layer, which not only isolates harmful gases, but also further improves the corrosion resistance of the inner wall, thereby reducing the direct exposure time of the main structural material.
In terms of manufacturing technology, FRP adsorption tanks generally use a variety of processes such as winding, hand lay-up or injection molding. Through multiple curing, the bonding strength between layers is ensured, and the key stress-bearing parts are thickened or reinforced to enhance the overall compression and impact resistance. The surface treatment process is also very important. The outer surface is often treated with anti-ultraviolet and anti-aging coatings to delay the natural weathering process in the outdoor environment.
During daily operation and maintenance, the FRP adsorption tank also needs to regularly check whether its lining and tank surface have cavitation, blistering or cracks. If initial damage is found, timely repair can effectively extend the service life. In addition, for some high-temperature exhaust gas or particulate matter working conditions, it is also possible to consider installing a pretreatment device at the front end of the system to reduce the direct impact on the FRP tank body.
When designing and manufacturing FRP adsorption tanks, manufacturers usually conduct a series of static pressure and corrosion resistance tests to verify the performance stability of the product under simulated extreme working conditions. At the same time, during on-site installation and commissioning, structural safety checks will be conducted based on actual parameters to ensure that the equipment maintains its structural integrity and corrosion resistance during long-term continuous operation.
