Environment-friendly rotational type multi-layer dry-distillation, drying and carbonization integrated furnace

Abstract

The invention belongs to the technical field of carbonization furnaces and provides an environment-friendly rotational type multi-layer dry-distillation, drying and carbonization integrated furnace. The furnace comprises an outer rotating cylinder, a middle rotating cylinder and an inner rotating cylinder which are arranged from outside to inside sequentially, wherein the outer rotating cylinder and the middle rotating cylinder are opened oppositely, and the outer rotating cylinder and the inner rotating cylinder are opened in the same direction; the outer rotating cylinder is arranged in a combustion chamber; a drying layer, a pre-carbonization layer, a carbonization layer which are communicated sequentially are arranged in the inner rotating cylinder, between the inner rotating cylinder and the middle rotating cylinder as well as between the outer rotating cylinder and the middle rotating cylinder; the inner rotating cylinder is connected with a feeding bin; a gas outlet is formed in one end of the outer rotating cylinder, and the other end is connected with a collecting tank; the gas outlet is connected with a flue gas recovery unit through a gas collecting device; guide plates are arranged on the outer rotating cylinder, the middle rotating cylinder and the inner rotating cylinder. The furnace is ingenious in conception, and solves the technical problems of simple design, lower heat energy utilization rate, high fuel consumption, long production cycle and unstable product quality of a single carbonization furnace in the prior art.

Description

technical field [0001] The invention belongs to the technical field of carbonization furnaces, and relates to an environment-friendly rotary multi-layer dry distillation, drying and carbonization integrated furnace. Background technique [0002] As people pay more attention to the living environment, the traditional carbonization process is gradually replaced by the environment-friendly continuous carbonization furnace. The continuous carbonization furnace is to carry out dry distillation, anaerobic carbonization and carbonization rate of wood chips, rice husks, peanut shells, plant straws, bark and other carbon-containing woody materials (particles or blocks with a diameter of less than 150mm) under high temperature conditions in the furnace. High-end charcoal machine series equipment. [0003] The continuous carbonization furnace adopts the advanced technology of recovery, purification and circular combustion of combustible gases such as carbon monoxide, methane and oxyge...
