Carbonization furnace for producing biomass charcoal

Abstract

The invention discloses a carbonization furnace for producing biomass charcoal. The carbonization furnace comprises a smoke tube, a rotary furnace body, a feeding hopper, a discharging hopper and an oil and gas discharging pipe, wherein the rotary furnace body is supported by rotary supporting rollers; the feeding hopper, the discharging hopper and the oil and gas discharging pipe are arranged on the rotary furnace body; the smoke tube is arranged in the rotary furnace body and is coaxial with the rotary furnace body; and the inner wall of the rotary furnace body is provided with helical blades or an angle which is more than 5 degrees and less than 30 degrees is formed between the coaxial line of the smoke tube and the rotary furnace body and the horizontal plane. The biomass charcoal is produced by the following steps that: a biomass material enters the carbonization furnace from the feeding hopper; a motor drives the carbonization furnace to rotate; the helical blades in the furnace stir the material and push the biomass material to move forwards or from top to bottom; the material absorbs the heat of the outer wall so as to evaporate the moisture; and the biomass material is carbonized and discharged from the discharging hopper. The carbonization furnace has the advantages of realizing continuous production, saving the energy resource, improving the production efficiency and reducing the labor intensity, along with simple production process, high efficiency, low labor consumption and low labor intensity.

Description

Technical field: [0001] The invention relates to the field of biomass charcoal, in particular to a carbonization furnace for producing biomass charcoal. technical background: [0002] Biomass charcoal (also known as charcoal) is a solid charcoal left by biomass bark, branches, fruit shells, sawdust, etc. put into a pyrolysis furnace for thermal decomposition. my country is a big country that produces and uses charcoal. The use of biochar At present, the existing biomass carbonization furnace cannot continuously produce charcoal. For example, the oxidation prevention pyrolysis furnace (patent number ZL200920062938.0) produces biomass charcoal. Every time a furnace of biomass charcoal is produced, the furnace must be shut down, the furnace cover is opened, and at a high temperature of several hundred degrees, water is artificially sprinkled to cool down the charcoal. Shovel it out again with a shovel, take out the biomass charcoal, then add biomass, cover the furnace cover and...

For example, the oxidation prevention pyrolysis furnace (patent number ZL200920062938.0) produces biomass charcoal. Every time a furnace of biomass charcoal is produced, the furnace must be shut down, the furnace cover is opened, and at a high temperature of several hundred degrees, water is artificially sprinkled to cool down the charcoal. Shovel it out again with a shovel, take out the biomass charcoal, then add biomass, cover the furnace cover and slowly heat up and carbonize; since the furnace body is cooled during the process of sprinkling water to cool down the charcoal, in the next carbonization process It needs to be re-heated, resulting in a large amount of heat loss, prolonging the carbonization time, complex production process, low efficiency, and people working at high temperature, physical exertion and labor intensity
