NOVELTY - Energy-saving and emission-reducing process flow of wood-based panel enterprise with crop straw as energy comprises (a) straw material; (b) unitizing straw; (c) manufacturing straw solid micro fuel; (d) burning straw solid micro fuel; (e) transforming heat amount; (f) heat amount utilization unit; (g) recycling waste heat; and (h) returning ash fertilizer into soil.    USE - The energy-saving and emission-reducing process flow is useful for wood-based panel enterprise with crop straw as energy (claimed).    ADVANTAGE - The evaluation index of combustion apparatus of straw fuel is greater than or equal to 95%; thermal efficiency is greater than or equal to 85%; it substitutes coal and waste wood and can realize the purpose of saving energy and material, protecting environment and reducing the cost on the premise of ensuring enterprise to normally produce; the energy conservation and emission reduction of enterprise is realized, which has important practical significance. The farmer can increase income through selling the crop straw as fuel. The product quality index accords with the demand of standard of middle density fiberboard of China.    DETAILED DESCRIPTION - Energy-saving and emission-reducing process flow of wood-based panel enterprise with crop straw as energy comprises (a) straw material; (b) unitizing straw; (c) manufacturing straw solid micro fuel; (d) burning straw solid micro fuel; (e) transforming heat amount; (f) heat amount utilization unit; (g) recycling waste heat; and (h) returning ash fertilizer into soil; the straw material of (a) uses corn straw and wheat straw which the water contents are not greater than 20%; uniting straw of (b), machining the crop straw into unit crushed aggregates according to demand of process through chaff-cutter and straw disintegrator; in order to obtain good granulation effect, sometimes adding proper accessory ingredient; manufacturing straw solid micro fuel of (c), manufacturing grain fuel with density of 1.1-1.4 g/cm3 and length of 10-30 mm and diameter of 6-8 mm through straw micro granulator; the heat productivity is reached to 4500-5000 kcal/kg; (d) burning straw solid micro fuel; transforming heat amount of (e), transforming the heat energy into steam or hot oil heating medium through heat transforming device; heat amount utilization unit of (f), using different heating devices according to the demand of production, for example, separating fiber through steam by thermofiner; or plate blank hot pressing through hot oil by hot-press; recycling waste heat of (g), the heat carrier transformed by heat energy has higher temperature and more heat amount; the pre-heated material and heat medium are used for recycling waste heat; and returning ash fertilizer into soil of (h), returning the ash component containing farm potash fertilizer remained after burning straw solid fuel into soil.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram for an energy-saving and emission-reducing process flow for wood-based panel enterprise with crop straw as energy (Drawing shows non-English language text).
