Embodiment Construction

[0015] The present invention will be further described below in conjunction with the examples.

[0016] Such as figure 1 with figure 2 As shown, the wood residue dryer used in the present invention for removing hard impurities is provided with a heating chamber 1, a feeder 2, a drying cylinder 3 and an exhaust fan 5, and one end of the drying cylinder 3 is connected to the heating chamber 1, The other end is connected to the exhaust fan 5; the drying cylinder 3 is provided with a feeder 2. By setting the waste discharge hole 4, the waste discharge pipe 6 and the waste discharge rack 7 at the discharge end of the drying cylinder 3, the hard impurities that have been at the bottom during the drying and rotating process can be removed, thereby reducing the abnormality of the subsequent pressing abrasive wear and tear, saving costs and ensuring production efficiency.

[0017] The waste discharge rack 7 is a U-shaped groove with a slope, which is convenient for the centralized ...

Abstract

The invention provides a preparation method of biomass fuel and special equipment thereof, which solves the technical problems of wasting resources of dryers, low production efficiency and environmental pollution in the prior preparation method of biomass fuel. Mix wood and straw; crush the above raw materials into granules; send the granules to a wood slag dryer for removing hard impurities and dry them; send the dried materials to an extruder for extrusion to obtain raw Material fuel; the wood residue dryer for removing hard impurities is equipped with a heating chamber, a feeder, a drying cylinder and an exhaust fan, one end of the drying cylinder is connected to the heating chamber, and the other end is connected to the dryer; the drying cylinder There is a feeder on the top, a waste discharge hole is provided at the discharge end, a waste discharge pipe is provided below the waste discharge hole, and a waste discharge rack is provided below the waste discharge pipe. The invention can be widely used in the field of biomass fuel preparation.

Description

technical field [0001] The invention relates to a fuel preparation method and its special equipment, in particular to a biomass fuel preparation method and its special equipment. Background technique [0002] Biomass fuel, as a new type of clean fuel using waste as raw material, has been vigorously promoted due to its advantages of energy saving, environmental protection, high calorific value and low price. [0003] The Chinese invention patent application with publication number CN 104073316 A discloses a production method of biomass fuel, and relates to a production method of low slagging biomass fuel. Biomass such as crop stalks, landscaping waste and sawdust is used as the main raw material, after being pulverized and dried, oxidant and anti-slagging agent are added, and biomass pellet fuel is obtained after mixing and granulating. [0004] However, this method also has some problems, for example, the ratio of raw materials is not perfect, and the calorific value of fue...
