Abstract
The invention discloses a method for producing charcoal by dryly distilling and pyrolyzing saw dust. The method is characterized by comprising the following steps: (1) heating and drying the saw dust at 265-272 DEG C and finishing drying until no steam is generated; (2) heating the saw dust dried in the step (1) to 360-380 DEG C and finishing pre-charring until no smoke is generated; and (3) heating the saw dust pre-charred in the step (2) to 495-510 DEG C, entering a charring stage and stopping heating when the smoke yield is reduced. According to the method, the saw dust is subjected to the steps of drying, pre-charring and charring, the steam heat energy generated by drying and the fuel gas generated by pre-charring and charring are recycled and the utilization efficiency of biomass is increased.
Description
Technical field
The invention belongs to biomass processes technical field, in particular it relates to a kind of use sawdust carbonization production Linesless charcoal
Method.
Background technology
Biomass energy is exactly the form of energy that solar energy is stored in chemical energy form in biomass, i.e., with biomass to carry
The energy of body.It directly or indirectly from the photosynthesis of green plantss, can be converted into conventional solid-state, liquid and gaseous state
Fuel, it is inexhaustible, nexhaustible, it is a kind of regenerative resource, while a kind of and unique reproducible carbon source.Biomass energy
Source technology is a kind of new energy technology with broad based growth future.
The content of the invention
It is an object of the invention to provide a kind of method that use sawdust carbonization produces Linesless charcoal.
The purpose of the present invention is by the following technical programs implementing：
A kind of method that use sawdust carbonization produces Linesless charcoal, comprises the steps：
（1）By sawdust heat drying, temperature is 265-272 DEG C, after producing without steam completes drying；
（2）By step（1）Dried sawdust is heated to 360-380 DEG C, after smokeless is produced completes pre- carbonization；
（3）By step（2）Sawdust after pre- carbonization is heated to 495-510 DEG C, into carbonization stage, when smoke yields reduce
Stop heating.
Further, step（1）The steam of generation carries out recuperation of heat；
Step（2）The off-gas recovery of generation；
Step（3）The flue gas of generation carries out dedusting, cooling, purified treatment.
The invention has the advantages that：
The present invention provide use sawdust carbonization produce Linesless charcoal method, sawdust is dried, pre- carbonization, carbonization,
Reclaim and be dried the steam thermal energy and pre- carbonization, the fuel gas of carbonization generation for producing, improve the utilization ratio of biomass.
