Continuous charcoal production equipment and method

Abstract

The invention discloses continuous charcoal production equipment and method, and the continuous charcoal production equipment comprises a splitting can, a stove, a metal shell, an insulation can, a support frame, a charging / discharging system, an air supply system, a cooling system and a temperature measurement system, wherein the splitting can is arranged on the metal shell; the upper end opening of the splitting can is communicated with a charging hopper and the lower end outlet thereof is communicated with a discharging conveyer; the upper end inlet of an oil / gas collecting and conveying system is connected with the splitting can through an oil / gas outlet on the splitting can; the lower end of the oil / gas collecting and conveying system extends to the upward side of the stove; the lower end outlet of the oil / gas collecting and conveying system is wrapped in an air outlet of the air supply system and faces toward the stove; and the stove is arranged below the discharging conveyer. According to the continuous charcoal production equipment, the continuous batch production of charcoal can be carried out in a low-speed heating condition, so that the difficulty that the pipelines are blocked by splitting oil / gas is solved; and the continuous charcoal production equipment has the characteristics of low energy consumption, no pollution and high efficiency, and can be widely applied to the carbonization of biomass.

Description

technical field [0001] The invention relates to a continuous biochar production equipment and method, belonging to the technical field of biomass carbonization. Background technique [0002] China's rapid economic development and massive consumption of fossil fuels have resulted in a continuous increase in greenhouse gas emissions. In response to climate change, China has put forward its own action target, that is, "by 2020, emissions per unit of GDP will be reduced to 40%-45% of the 2005 level." This target was included as a binding indicator in the mid- and long-term planning for national economic and social development during the "Twelfth Five-Year Plan" period and later, and corresponding measures were formulated to implement it. China is a large agricultural country, and the production of crop straw alone can recover 900 million tons of CO from the atmosphere every year. 2 . If pathways for carbon sequestration can be found in agriculture, the CO recovered from bioma...
