Description
Technical field
The present invention relates to heat preservation construction material and industrial heat preservation industry and the useless field of environmental protection and energy saving profit, particularly magnesite straw ash heat insulating products.
Background technology
Society, along with rapid development of economy, energy development and ecological protection problem also more and more cause people's concern.How between making rational use of resources and preserving the ecological environment, to find balance, development sustainable development path, development new forms of energy, energy-conserving profit waste reduces discharging, the ecological permanent objective that has just become people constantly deliberately to pursue of protection.
In recent years, a kind of emerging renewable energy resources constantly cause various countries to be paid close attention to, and Here it is the straw energy.Stalk is that farm crop are by plucking the cauline leaf staying after threshing.Mainly contain the straw kinds such as corn, wheat, paddy rice, Chinese sorghum, soybean, bark.China is traditional agriculture big country, it is estimated that agricultural crop straw annual production reaches more than 700,000,000 ton, wherein can be used as the straw total amount that the energy is used and approximately reaches 3.76 hundred million tons.Owing to lacking effectively management and utilizing, most stalks are destroyed by fire privately, have not only caused the huge wasting of resources, and the destruction of environment has also been produced to immeasurable impact.Therefore, aspect the Infrastructure of reinforcement rural area, the generating of develop actively straw, improves rural power grids, is also put in the 11 five-year plan of country.Since First straw combustion power generation factory is built up in Jinzhou City, Hebei province, the straw power generation project that national each province and city also start in succession as Jiangsu, Anhui and other places.This has not only effectively carried out effective centralized management utilization to straw, and the environmental disruption of avoiding random crop straw burning among the people to bring, simultaneously again for people provide a kind of novel renewable energy source.
Yet just when people start just to taste straw power generation and offer convenience to people's lives, new difficult problem is going in face of people silently again.That is exactly the byproduct of straw generating, the processing problem of straw ash.A middle-size and small-size straw power house, straw ash average year output just can reach 40,000 tons more than.The reasons such as the industrial or agricultural industrial structure due to China, so the straw ash of enormous amount cannot effectively be processed or be used, not only badly influenced the normal operation of straw electricity power enterprise, hindered further developing of the straw energy, even environment has been caused to destruction to a certain degree.As can be seen here, how the surprising straw ash of these quantity is used, Cheng Liao entire society urgently wishes the new problem solving again.
Meanwhile, people start the sight of dealing with problems to invest building heat preservation building materials and industrial heat preservation industry because building materials and industrial heat preservation industry not only consumption is huge, and lasting demand property is strong.Especially emerging heat preservation construction material industry, consistent advocating utilized waste recovery recycling, can solve on the one hand a processing difficult problem for dead meal, can better people's living environment for building energy-saving reduces discharging again on the other hand, improves the quality of living and makes huge contribution.Therefore, research and develop a kind of heat insulating products that is raw material by straw ash, just become the key point overcoming the above problems.
