Hot compression plasticizing molding charcoal and manufacturing method thereof

Abstract

Raw materials of hot compression plasticizing molding charcoal comprises at least fuel wood, shrubs, branches, bark, wood processing residuum or waste artificial boards and the like, with alkali lignin serving as two components. A molding method is hot compression plasticizing molding. After being molded, discharged materials are cut into required specifications through saws and enter a carbonization furnace to be carbonized in a pile mode. The hot compression plasticizing molding charcoal is obtained by cooling after full carbonization. The fuel wood, the shrubs, the branches, the bark, the wood processing residuum, the waste artificial boards and the like are difficult to utilize when machine-made charcoal is manufactured. The fuel wood, the shrubs, the branches, the bark, the wood processing residuum, the waste artificial boards and the like are burned or corrupted, and therefore the utilization degree is not high. The alkali lignin is a difficult problem of black liquid recycling management, generated through acid-out treatment after pulping by means of a caustic soda method or a sulfate method, has the characteristics of high viscosity and a high heat value. After being mixed, the two components are molded by means of the hot compression plasticizing molding technology and carbonized, and therefore the charcoal is obtained with the high heat value.

Description

【Technical field】 [0001] The invention relates to the technical field of carbon production. 【Background technique】 [0002] The firing of charcoal in the prior art is mainly the firing method of machine-made charcoal, and the traditional earth kiln firing wood or fuelwood has been basically replaced by machine-made charcoal due to resource problems and national policies. [0003] Mechanism charcoal firing method generally uses wood sawdust as the main raw material, branches, rice husks, bamboo chips, peanut skins, sunflower seed husks, furfural residues, wine residues, bagasse, corn cobs, coconut shells, coffee shells and north-south charcoal Square crop straws can also be used after being crushed, but the machine-made rod and screw extruder has strict requirements on the moisture content and fineness of the raw materials, and often needs to be repeatedly crushed several times. Energy consumption and labor increase the manufacturing cost, which is very difficult in actual pr...
