Desciption

System Introduction
“Continuous rotatory drying and carbonizing system” is an efficient carbonization system specially designed for processing biomass raw material. This system make the raw materials undergo drying, pre-carbonization and carbonization in turn, and finally deeply converted into biocarbon and pyrolysis gas by a series of fine temperature control in an oxygen-free environment. The pyrolysis gas in the system provides self-heating for the carbonization system through combustion, and the surplus hot flue gas is used for heating the drying process. After the high-temperature flue gas is used for thermal energy, it is purified through the flue gas purification system to ensure that it is emitted to the standard.

Principle  Rotert  Braised Biomass is thermally degraded under oxygen-free conditions and ultimately generates biochar and combustible gas. The char yield is high.  Biomass is burned in an anoxic (low oxygen content) environment to finally obtain biochar, and the char yield is relatively low. 
Production cycle  2 days 23 days The processing is divided into 7 steps: "coarse crushing, fine crushing, waste heat kiln drying (1 d), continuous pyrolysis carbonization, molding (1 d), low-temperature drying, and packing (1 d)", with a total processing cycle of 3 days.  The processing is divided into "coarse crushing, fine crushing, fermentation (12d), powdering, drying, rod extrusion (1d), kiln loading, heating, smoldering (5d), cooling (5d), sorting, and packing (1d) )" 12 processes, with a total processing cycle of 25 days. 
Energy utilization  All production heat sources are self-supplied, saving 30% of electricity.  Production requires other heat sources.  When biochar is obtained through pyrolysis, a large amount of flammable gas is obtained. Its gas combustion meets the entire production heat source supply, and its energy is fully utilized.  Stewing requires part of the fuel to ignite the mechanism rod to finally obtain biochar. The combustible gas generated during the process is used for the kiln body to stew. The drying of biomass raw materials requires the supply of other heat sources, and the energy utilization rate is low. 
Quality assurance  Mechanized automatic control  Manual experience control  The production line adopts PLC/DCS intelligent control system to realize automatic control and linkage adjustment of control points, and has functions such as data collection, calculation, alarm and automatic correction.  The carbonization process is entirely controlled by human intervention and experience, making it impossible to form a standardized operating process and causing unstable product quality. 
Environmental situation  It occupies a small area, has a clean environment, has low exhaust emissions and has been treated to meet emission standards.  The workshop has a large amount of smoke and dust, pungent odor, and direct or partial direct discharge of vapor and liquid.  The continuous furnace is fully closed to collect pyrolysis gas. After the gas is fully burned in the hot blast furnace, the waste heat is supplied to each process. After the utilization is completed, the exhaust gas is environmentally friendly and discharged to meet standards.  Hundreds of equipment are scattered and arranged, covering a large area. When the raw materials are formed, thick smoke is generated due to high temperature, high pressure and surface carbonization, and cannot be collected in an organized manner. The pyrolysis gas and liquid produced by carbonization are usually arranged in line or partially arranged in line. 

Features
1. The traditional carbon production procedure was optimized from 12 to 7, and the processing cycle was shortened from 23 days to 2 days.
2. Fully enclosed oxygen-free rapid carbonization, combustible gas recycling, saving 30% energy and 20% raw materials than traditional processes.
3. Intelligent control system, product standardization.
4. The production environment is good. The exhaust gas is discharged up to standards after environmental protection treatment.
