Hot compression plasticizing molding bamboo charcoal and manufacturing method thereof

Abstract

Raw materials of hot compress plasticizing molding bamboo charcoal at least include two components of bamboo processing residuum and alkali lignin. A molding method of the bamboo charcoal 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 bamboo charcoal is obtained by cooling after full carbonization. A manufacturing method of the hot compress plasticizing molding bamboo charcoal takes full advantages of characteristics of high heat value and high viscosity performance of alkali lignin, full utilizes leftover materials, fractured bamboo, bamboo roots, bamboo tips, bamboo branches and the like after selection of materials of bamboo products, bamboo flooring, bamboo plywood and the like. In addition, products are standard and high in fixed carbon content and charcoal obtaining rate, production time is short, the output is high, and large-scale production can be achieved. Besides, a large amount of lignin is generated in the process of pulping and papermaking, and the stress of environmental management is reduced. By means of the hot compression plasticizing molding bamboo charcoal and the manufacturing method of the hot compression plasticizing molding bamboo charcoal, two resources placed in wrong places are placed together and are changed into energy.

Description

Technical field

[0001] The invention relates to the technical field of carbon production.

Background technique

[0002] In the utilization of biomass energy in the prior art, biomass is used as raw material for mechanism carbon, but except for sawdust left over from the wood industry, due to the high requirements of dryness and fineness of crushed materials by rod making machinery, the utilization of biomass in general There is a problem of difficult crushing, such as bamboo processing residues, which mainly include bamboo tips, cut ends, bamboo branches, bamboo chips, etc. The large bamboo processing residues are almost difficult to crush and be used. Bamboo chips are flammable, and they are lost by flue drying It is also large, so in actual production and consumption, bamboo charcoal is basically obtained by firing raw bamboo or pyrolyzing carbonization kettles, and the resulting charcoal has irregular shapes, including flakes, cylinders, and granular and Powder, etc....

Examples

Embodiment 1

[0014] Take bamboo chips as raw material, dry them until the moisture content is below 15%, add 110Kg of dried bamboo chips to each equal part, add 50Kg of alkali lignin, stir evenly, weigh and reset the frame-type hopper, pave and organize embryos and enter the hot press, at a maximum of 5MPa Under the conditions of pressure and temperature of 155°C, the molding specification is 2400mm*1200mm*50mm semi-finished products; after being discharged, it is cut into 400mm*200mm*50mm specifications and stacked into a carbonization furnace for carbonization.

Embodiment 2

[0016] Take small-diameter bamboo and bamboo branches as raw materials, air-dry them naturally until the moisture content is below 20%, weigh 120 kg per bundle, put the above materials in a frame-type hopper while paving, and evenly apply 40 kg of alkali lignin to form embryos into the hot press , under the highest pressure of 5MPa and temperature of 165°C, the molding specifications are 2400mm*1200mm*50mm semi-finished products; after being discharged, they are cut into 400mm*200mm*50mm specifications and stacked into the carbonization furnace for carbonization. Shaped bamboo charcoal.
