BIOMASS GAS AND BIOMASS CHARCOAL PREPARATION SYSTEM

摘要

The present invention relates to a biomass gas and biomass charcoal preparation system, including three successive working units: a feeding unit, a pyrolysis reaction unit, and a discharging unit, and further having a pyrolysis reaction control system. The pyrolysis reaction unit has a pyrolysis reaction body. The pyrolysis reaction body is provided therein with a helical propulsion device and an air supply device. The pyrolysis reaction body is a rectangular cavity having a metal shell. The cavity of the pyrolysis reaction body is divided into two parts: an upper part and a lower part that are separable. In the present invention, the pyrolysis reaction body is provided therein with a thermal insulating layer, which effectively separates the metal shell from a high-temperature reaction medium, so requirements for the heat resistance of the material of the cavity of the pyrolysis reaction body are lowered, a common carbon steel material can be used and the cost is reduced, and the metal shell is effectively relieved of thermal deformation, and heat loss is reduced; the pyrolysis reaction body is divided into an upper part and a lower part, so it is easier to disassemble wearing parts on the bottom of the reaction body to facilitate maintenance and replacement.
