Physical method straw fibrosis

Abstract

Physical method straw fibrosis is characterized in that a high-solid preparation technology based on heat and pressure for plant and straw fibrosis and an efficient mechanism of the high-solid preparation technology are conceived, and the physical method fibrosis taking whole-process sealing and temperature and pressure bearing as a cleaning mechanism is constructed. Main components are a wind power raw material preparation part, a forced raw material input part, a raw material medicine-free digester and heat supply part, a material discharging and differential pressure conveying part, a primary high-solid defibrator set and solid-steam separation part, a plurality of primary fiber discharging and differential pressure conveying parts, a plurality of high-solid defibrator sets and solid-steam separation parts, a forced fiber output and waste heat recycling part, a separation steam recycling and reusing part, a preheating water supply part and the like. The physical method straw fibrosis disclosed by the invention has the beneficial effects that a physical method is adopted to fibrillate plants and straw, so that the last kilometer of efficient and large-scale conversion between straw disposal and recycling can be promoted and broken through.

Description

technical field [0001] The invention relates to the fields of plant fibrosis, straw resource utilization, agricultural and rural ecology, clean production, circular economy, energy saving and environmental protection, and specifically relates to the physical method of straw fibrosis. [0002] technical background [0003] The current straw is mainly smashed and buried in the field. First, it affects soil planting because it is not degraded in time, and second, it increases soil diseases and insect pests in farmland because the straw carries parasites. So, it's neither scientific nor sustainable. [0004] Both wood and straw are the main source of lignocellulosic fiber, but straw is a metabolic renewable resource; straw is suitable for cooking and easy to grind for fiber production, and because of its strong water absorption, it is important to control the solid-liquid ratio or improve the solid-liquid separation efficiency. [0005] The former straw pulping and papermaking h...
