Introduction

As equipment gradually ageing, most and wind- driven dynamo also arrived to retire time. Should demolished wind- driven dynamo manage like where? The only question after fan is demolished is blade processing. Wind cable industry is developing new-style lamina to handle way, for instance blade recycle or production can reclaim blade.

General view:

• The material of 90% can be in French wind-force dynamo directly mainland undertakes reclaiming.
• The only question after fan is demolished is blade processing. Blade is made by composite material, optimal processing technique is the recycle after coming out depart of every kinds of composition.
• But, decompose polymer from inside aggrandizement fiber very complex.
• Industry of French wind cable needs every year to handle since 2008 1 to 15 thousand tons of polymer.
• Wind cable industry is developing new-style lamina to handle way, for instance blade recycle or production can reclaim blade.

As equipment gradually ageing, wind cable industry is about to reach the turning point of the industry. Denmark enlists in army the wind- driven dynamo that time exceeds 15 years occupies gross 50% , germany achieves 40%[1] . Although wind- driven dynamo carries travel life is 20 years, but wind- driven dynamo of Europe changes actually time is in 9 to 27 years between. The wind- driven dynamo that France enlists in army more than 15 years occupies total installed capacity to be less than only 5% . French environment and energy management board point out, most dynamo is enlisting in army 15 after coming 20 years, change. According to report of association of European wind energy, in the near future European dynamo changes speed may be accelerated, change capacity from 2020 annual 3 auspicious tile covers with tiles to the 6 auspicious 2030 [2] .

01 retire fan processing

So new issue appeared, if why is demolished wind- driven dynamo handled? According to France department of housing of program of environment of large area of large the eastpart part says [3] , wind- driven dynamo 90% form by concrete and steel material, average weight mixes 246 tons for 840 tons respectively. Concrete and steel reclaim very easily use, the market is very big. The other data such as cast-iron, copper can reclaim likewise, secondhand the market is very mature, and Europe has big company to buy the home. The Amandine Volard of French environment and energy management board also thinks, the compositive material of 90% can be in generator of every typhoon power French mainland reclaims, the market perfect and body amount is large.

The compositive material of 90% can be in generator of power of “ every typhoon French mainland reclaims. ”

Reclaim only question is blade. Blade is made by composite material, with polymer (epoxy resin, polyurethane, polyester) for matrix, fiber (maritime wind report is commonly used fibre glass or carbon fiber) to strengthen put oneself in another's position. Optimal processing technique is the recycle after coming out depart of every kinds of composition. But Confucianism strap 0 waste of lamina of institute of technology of · Fan Erna to study a project (ZEBRA project) chief Céline Largeau points out, detached fiber and polymer are very difficult. Depart has —— of a few kinds of methods to heat up solution, chemical dissolvent to decompose, aerification, abrade.

These craft can realize fiber and polymer to reclaim, but efficiency is not tall [4] . Hot solution, abrade the physical property that waits for the existing technology that uses maturely, extensively to be able to change fibre glass, not only cost is high, and reclaim the fiber photograph of earning compares common thread price expensive, quality is low. Deliquescent can reclaim only the fibre glass with whole pattern and can reclaim colophony.

Industry of cable of “ France wind begins from 2028, every year will 1 need to handle to 15 thousand tons of polymer. ”

Answer knock off art very small effect, need to waste a large number of solution, water, the sources of energy, still immature. Abandon the processing technology that old lamina matures exclusively, it is to send cement plant to burn as fuel. Germany is undertaking a large number of equipment change, those who adopt is to burn method [5] , the grog of residual interfuse cement after burning. Confucianism strap institute of technology of · Fan Erna to estimate, industry of French wind cable begins from 2028, every year will 1 need to handle to 15 thousand tons of polymer [6] . But a lot of industries need to handle waste through cement line of business, more than it is wind report. Rely on cement line of business to cannot digest so many blade polymer only.

02 reclaim with recycle

Because a variety of elements are affected (the article after seeing) , wind cable industry is winding debit way in the lamina with new research and development. A little detached craft still is in development the test is inchoate, wait like electrolysis of deliquescent, aerification, high pressure. Wait for relatively mature craft to heating up solution, reforming inside course of study optimize, with period fiber of special type of translate into of will useless old lamina. For instance, the Bcircular of newly established enterprise that devotes oneself to polymer to reclaim is in its R3FIBRE project [in 7] , will reclaim fiber adds business to use cement in, enhance cement performance. Supplying chain also is the ground of blade fibrous use force. Largeau says, 0 waste study blade one of targets of the project are to seek industry of need lamina fibrous, automobile manufacturing industry is a very good example. Still having kind of a kind of processing is recycle. Advisory company Bax &Company reports in an analysis middle finger goes out [8] , although reclaim,not be optimal processing technique, but still be to use most method, can consider to use blade at the wall outside the building.

Still having a kind of way is the new-style lamina that research and development can reclaim completely. Some manufacturer with “ 0 wasteful ” are a target, be dedicated to finishing new lamina to develop before 2040 [9] . But first of beautiful Sa of Xi Menzi song of company of second birth energy can reclaim completely blade appeared on the market 2021. This lamina uses the composite material of new-style colophony and fibre glass, chemical method depart can be passed after demolishing. The ZEBRA project that French scholar straps institute of technology of accept of · every Er pays close attention to —— of colophony of another kind of innovation mainly thermoplastic colophony. Thermoplastic colophony and the composite material that a kind of high-powered fibre glass constitutes also can pass chemical method to reclaim. Largeau says, the high-powered fibre glass of research and development of composite material company includes Ouwensikening can reclaim fibre glass, because recycle can undertake after this depart. The colophony after depart is OK also recycle. The one big challenge that these new-style lamina face is how to measure its footmark of complete lifecycle carbon. Analysis of this kind of complete lifecycle still does not have pattern plate, nevertheless Largeau expresses, the institute is about to develop the analytic model that applies to ZEBRA lamina, show level to check a result good.

Wind report lamina reclaims, imperative

Retire fan is increasing, wind cable industry is beginning to answer. France promulgated on June 22, 2020 " wind- driven dynamo installs act " [10] , ask the implementation before July 2022 retires fan lamina 90% recycle or reclaim, 95% recycle come true before January 2024 or reclaim. Amandine Volard points out, the wind power plant that France dismantles the first times already reached afore-mentioned goals. Recently, the standards of grading that windward cable project bids increased French sea to reclaim rate, drive of this kind of economy conduces to raise an industry to reclaim rate. Besides legislation, economic crisis also promoted the development that blade reclaims. Largeau points out, the production of fibre glass needs a large number of the sources of energy, nearly a few months because economy is stagnant, manufacturing cost jumps, the price competition ability that brings about reclaiming fibre glass rises. In addition, will deserted lamina burns simply or fill bury go against trade figure, public opinion might cannot small inspect.
