Technical Field

The invention relates to the fields of plant fibrosis, straw recycling, agricultural and rural ecology, clean production, circular economy and the like, in particular to straw fibrosis by a hot pressing method.

Technical Field

At present, the majority of domestic waste crop straws are mechanically smashed and buried in farmlands.

Because the parasites of the straws are buried in farmlands along with the straws, the soil diseases and insect pests all over the country are increased to different degrees.

Meanwhile, too many pieces of straws are broken and buried in farmlands, and the straws are not degraded in time, so that the farmland soil all over the country is damaged to different degrees, and the normal growth of crops is influenced.

Therefore, the abandoned crop straws are broken into pieces and buried in the farmland in China, and the method is neither scientific nor sustainable.

It is well known that wood fiber is one of the basic substances of human society; the wood fiber is mainly derived from wood and straw in plants.

Compared with wood, the straw has the advantages that: the straw has a light thin-skin structure, so the straw is suitable for cooking and easy to be ground; however, since the water-absorbing property is very strong, the solid-liquid separation is important; meanwhile, the wood fiber production process using the straw as the raw material has short relative flow and low energy consumption.

At present, wood fiber in the world mainly takes felled forest resources as raw materials. However, the vegetation rate in China is low, so that the lack of forest resources is one of the basic national conditions; meanwhile, the domestic papermaking capacity is about one hundred million tons per year, which accounts for about one fourth of the global capacity, so the domestic papermaking wood fiber raw material mainly depends on import.

In China, straw pulping and papermaking have been carried out, and the main characteristics are as follows: the basic processes of cooking, spraying, washing and the like of wood pulping and papermaking are adopted and used, and laggard equipment and facilities with high energy consumption and heavy pollution are added; wherein, the spraying and washing wastes energy and produces sewage, which is a fatal defect, and is eliminated and banned.

Therefore, in order to overcome the defects of the existing production mode and the technology and equipment thereof, the invention optimizes heat energy, machinery and hot pressing application thereof from the perspective of green ecology, energy conservation and environmental protection, provides a new plant and straw fiberization technology and new equipment, and aims to further promote and improve the resource utilization of crop straws.
