Water-cooled continuous dry distillation type stalk powdered carbon machine

Abstract

This invention relates to a water-cooling continuous carbonization machine for producing carbon powder from stalk. Multi-stage carbonization pipes are set in a carbonization chamber. A screw conveyer is set in each carbonization pipe. The screw conveyers are connected via double wheels and double chains. The screw conveyers in two carbonization pipes in upper and lower stages have reverse propelling directions. The propelling endpoint of the upper stage carbonization pipe and the propelling start point are through connected via a discharge passage. A gas collection chamber is set in the carbonization chamber to recover and recycle residual gas by an injection blower. An adjustment valve and a pressure reducer are set on the air return pipe. A discharge hopper is set in the circulating cooling water tank, and isolated from the circulating cooling water tank to realize dry cooling of carbon powder. The machine can ensure even speed continuous propelling of the raw material. The flue gas can be re-combusted, thus can avoid coal tar harm. The machine has such advantages as high carbonization temperature, no exhaust gas, low labor intensity, high production efficiency and high carbon powder quality.

Description

technical field [0001] The invention relates to a device for making charcoal by using straw, in particular to a water-cooled continuous dry distillation straw charcoal powder machine. Background technique [0002] At present, the production method of straw charcoal powder mostly adopts the soil method pit method, that is, dig a pit on the ground and ignite it, sprinkle the straw on it, carbonize one layer and sprinkle one layer, after reaching a certain amount, seal the soil, compact it and cool it down to produce charcoal share. Although this process is simple, the carbonization temperature is low and the carbonization quality is poor; it is naturally cooled and cannot be continuously operated, and the production efficiency is low; the production cycle is long and the labor intensity is high; a large amount of smoke is emitted during the production process, which seriously pollutes the environment. [0003] In the coke production process, the continuous production method o...
