Closed charcoal preparation apparatus

Abstract

The invention relates to a charcoal preparation apparatus, and especially relates to a closed charcoal preparation apparatus. A technical scheme is characterized in that the apparatus comprises a temperature controller (1), a heater box (2) and a pyrolysis tank (9), and when charcoal is prepared, organic matters enter the pyrolysis tank (9), a lid (8) at the upper portion of the pyrolysis tank (9) is screwed up, the pyrolysis tank (9) is put in the heater box (2), and heating pyrolysis is carried out. The heater box is opened after the pyrolysis reaction, the pyrolysis tank (9) is cooled to room temperature, and then the prepared charcoal is taken out. The apparatus has the characteristics of ingenious conception, reasonable design, and realizes reduction of the pyrolysis temperature, shortening of the organic matter pyrolysis time and increase of the charcoal preparation efficiency by preparing charcoal through pyrolysis of organic substances in closed environment; and the apparatus can ensure anaerobic environment and improve the charcoal production rate through pyrolysis of the organic matters in a closed tank.

Description

technical field [0001] The invention relates to a biochar preparation device, in particular to a closed biochar preparation device. Background technique [0002] Biochar refers to the pyrolysis of biomass materials under anoxic or oxygen-limited conditions to remove the oil and gas in the biomass. It has the characteristics of refractory, stable, highly aromatized, and rich in carbon elements. , is generally considered to be a type of black carbon. Relevant studies have shown that biochar has a huge surface area and internal voids, has the characteristics of high negative charge, strong ion exchange capacity, and excellent adsorption performance, and has been widely used in the fields of environment and agriculture. At present, there are many devices for preparing biochar, such as patent 2011202616857, patent 201120403832.X, etc. However, these devices are more complex in structure, larger in size, and higher in price, which will virtually increase the cost of scientific r...

AI Technical Summary

Problems solved by technology

However, these devices are relatively complex in structure, large in size, and high in price, which will increase the cost of scientific research virtually.

When the muffle furnace prepares biochar, dense fumes with high humidity are released at the initial stage of organic matter pyrolysis, which can easily cause the heating wire of the muffle furnace to be short-circuited and damaged, and the production efficiency is low
