China Finds Ingenious Solution for Its Decommissioned Wind Turbine Blades

Many of China’s wind turbine blades are moving towards retirement, and researchers have come up with a creative way to re -use giant elements.

A Study Earlier this summer, published in International Soil and Water Conservation Research Journal, scientists suggested to rebuild the decomitioned wind turbine blades in the sand control system. Namely, sand barriers. The two problems of the procedure can be solved: dealing with old blades and looking for the best sand control system.

Researchers wrote on the paper, “With high strength and durability, air turbine blades can be cut directly into sand barriers.” “This approach does not only address the recycling challenges of decomitioned wind turbine blades, but also reduces the deficiency of windbreaks and sand stability materials in the desert and in Gobi regions.”

Two birds with a stone

In dry and semierid regions, both air can destroy both human and natural landscapes, and sand control system such as sand barriers aims to reduce economic loss and protect habitat. Although the sand and branches made of reeds and branches are cheap, easy to build and environmentally friendly, they are short -lived and do not hold well for the extreme environment.

More effective artificial sand control materials do not provide the perfect solution, as they face challenges in the high -air regions as well as in high air. Like this, people sometimes become a strong barrier made of cement, metal and rocky sand. In the end, the materials should be strong, long-lasting, air-abrasion-resistant, thermally stable, available, with reasonable prices and optimal pooroi.

In the case of the air energy industry, the question of what should be done with the old air turbine blades face high expenditure and complex traditional recycling processes, in addition to the risk of pollution in inappropriate management.

As a result, researchers investigated the effectiveness of sand barriers made from decomised or damaged air turbine blades. “First, we have tested the mechanical properties of these elements, in which ultraviolet (UV), including aging, thermal stability, curved energy and loss resistance,” researchers explained on paper. “Secondly, through the air tunnel tests and numerical simulations, we have analyzed the traditional nylon net sand barriers and analyzed the stable effects of new sand barriers and sand.”

The application of real -life

The method reveals that the new barrier loss rate can be 56% lower than wood compound materials and its curved energy was 14 times higher. Researchers also learned that 20% of Porosis was the best for the reduction of sediment transport.

“Therefore, new perforated sand barriers made from decomitioned or damaged air turbine blades are of great UV and decay resistance, high energy and thermal stability, recycling and long service life,” researchers said in conclusion. “It combines the perforated structure of flexible sand barriers with the energy of flexible sand, it makes it suitable for strong air, large temperature variations and acute UV radiant zones, which have significant potential to apply in sand control practice.”

The study is the final reminder of an age-of-one-person’s trash to another person’s treasure. Or, in this case, the garbage of an industry is the solution of another.
