Problems solved by technology

Both of these two carbon-making methods have certain deficiencies in the production process. The former has strict requirements on the water content and fineness of biomass raw materials during the processing of biomass raw materials. During the curing process of raw materials (that is, during molding), the temperature requirements are also high; while the latter needs to add combustion-supporting, puffing, and binders (charcoal synthetic agents) during the charcoal powder molding process, which also appears in the process of producing charcoal synthetic agents. It is very complicated. It must be made of non-metallic minerals through calcination, cooking, electrolysis and filtration to make this synthetic agent. Not only the production process is relatively complicated, but also the production cost of charcoal is increased; what is more prominent is that the two This method of making charcoal is more polluting to the air

Embodiment Construction

[0009] Put the biomass raw material with a moisture content of 10-60% into the carbonization furnace for carbonization treatment. After the temperature in the furnace reaches 300 °C, the temperature in the furnace can reach above 700 °C by adjusting the size of the air inlet of the carbonization furnace; When the temperature in the furnace is 700°C, the carbonization time is maintained for 10-12 hours, and then the carbon is discharged. 40-45% water, 2.5-3.5% starch and wood tar recovered from the carbonization furnace and drying furnace are added to the carbon material. 4-8%, the crushed carbon powder is kept in the molding machine, and the molding pressure is kept at 10-14kg / cm 2 , and make carbon rods according to the specifications required by customers, and then dry the carbon rods in a drying furnace at a temperature of 70-80 ° C for 29-31 hours. Qualified high-temperature carbon with no broken corners, flat surface and smooth carbon rods is good for packaging.

Abstract

The process of making high temperature charcoal includes the steps of: treating biomass material, charring the biomass material,, crushing charcoal, forming in a forming machine, stoving formed charcoal rod, and packing high temperature charcoal product. The present invention needs additional heat source for baking high temperature charcoal, has wood tar added into crushed charcoal, can produce high temperature charcoal with agricultural and forestry wastes and make best utilization of resource, and is environment friendly.

Description

technical field [0001] The present invention relates to a firing method of high temperature carbon. Background technique [0002] Generally, synthetic charcoal is made by pulverizing various biomass raw materials such as crops, orange stalks, branches and leaves, sawdust, rice husks and wastes after reasonable coordination, extruding into rod-shaped fuel at high temperature, and then carbonizing the rod-shaped fuel through carbonization equipment. Machine-made carbon, also known as the method of forming first and then carbonization, the process flow is: biomass raw material → biomass raw material solidification → molding material → carbonization → molding carbon; Material raw materials such as crop stalks, branches and leaves, sawdust, rice husks and wastes are reasonably combined to form carbon powder under certain conditions, and then calcined, cooked, and electrolyzed with a non-metallic mineral with combustion-supporting, puffing, and bonding effects. , After the charco...
