China finds a prominent solution to wind turbine blades that are stopped

Several wind turbine blades in China are close to retirement, and researchers have reached a creative way to reuse giant ingredients.

in Ticket It was published earlier this summer in the Journal of the Magazine for the Preservation of Soil and International Water. Scientists propose wind turbine blades that have been turned on in the anti -sand measures. It is in sand barriers. The approach can be the solution to two problems: dealing with old blades and finding controlled sand control measures.

The researchers wrote in the paper: “The wind blades of wind turbines with high strength and durability can be cut and drilled in sand barriers,” the researchers wrote in the paper. “This approach not only addresses the challenges of recycling for the window turbine blades that have been stopped, but also reduces the lack of wind and sand installation materials in the desert and the Gobi areas.”

Two birds with one stone

In arid and similar areas, winds can cause chaos on both human and natural landscapes, and control of sand controls such as sand barriers aim to reduce the resulting economic losses and protect habitats. While sand barriers such as reeds and branches are inexpensive, easy to create, and environmentally friendly, they are short -lived and do not withstand well for harsh environments.

The most effective artificial sand controls do not provide perfect solutions, as they also face challenges in very great areas along the railway. As such, people sometimes resort to stronger barriers made of materials such as cement, minerals and rock sand. In the end, the materials should be strong, long -term, wind -resistant, thermally stable, available, affordable, and perfect firmness.

As for the wind energy industry, the issue of what must be done with old wind turbines faces high costs and complex traditional recycling operations, in addition to the risk of pollution in the case of incorrect management.

As such, the researchers have investigated the effectiveness of sand barriers made of rural turbine blades that have been suspended or damaged. “First, we tested the mechanical properties of this substance, including the resistance of UV (UV) aging, thermal stability, the power of bending, and the resistance of corrosion,” the researchers explained in the paper. “Second, through the experiences of wind tunnels and numerical simulation, we have analyzed the effects of shelter stabilization and sand in the new sand barriers with a different porous compared to the traditional nylon sand barriers.”

Apply real life

The approach revealed that the new barrier erosion can be 56 % less than the wooden compound materials, and the bending power was 14 times larger. The researchers also found that the 20 % porosity was the best to reduce the transfer of deposits.

“Therefore, the sandy barriers that are easy to penetrate from the rural turbine blades that have been suspended or damaged have an excellent resistance to UV rays, corrosion, high strength, thermal stability, recycling, and long service life,” and the researchers concluded. “It combines the porous structure of flexible sand barriers with solid sand barriers, which makes it good suitable for areas with strong winds, changes in large temperatures, and intense ultraviolet radiation, which have great potential for application in sand control practices.”

The study is the final reminder of an old saying-the trash of one person is the treasure of another person. Or, in this case, the garbage in the industry is a solution to the other.
