Abstract

The invention discloses a biomass carbonization pretreatment process, which comprises a step of heating biomass at a temperature of 270 to 280 DEG C to dispel the water steam. The biomass carbonization pretreatment has the advantages that before pyrolysis, biomass is pre-heated to remove water in biomass in advance, the carbonization effect in pyrolysis is improved, the pyrolysis carbonization effect is enhanced, the discharged water is condensed, the environment is not polluted, and raw material drying equipment is not needed.

Description

Biomass carbonated preprocessing process
Technical field
The present invention relates to charring process field, especially a kind of biomass carbonated preprocessing process.
Background technology
Biomass can produce many by-products, such as coal gas, tar in carbonization process.Need to make in carbonization process simultaneously Substantial amounts of heat is used, high-temperature retorting (about 900～1100 DEG C), medium temperature carbonization (about 660～750 DEG C) can be divided into and low temperature distillation is (about 500～580 DEG C).Which type of pyrolysis temperature selected actually in actual production, because when, because of ground, because of product structure, because of life Depending on producing purpose, the control of pyrolysis temperature can be adjusted by switch board.
The content of the invention
The present invention is directed to the deficiencies in the prior art, proposes a kind of biomass carbonated preprocessing process, easy to operate, carbonization effect It is really good.
In order to realize foregoing invention purpose, the present invention provides technical scheme below：A kind of biomass carbonated preprocessing process, Including procedure below：By biomass in 270～280 DEG C of heating, vapor is discharged.
Further, the vapor to discharging carries out condensation process, obtains condensed water.
If due to containing large quantity of moisture in biomass, during pyrolysis charring, the quality and yield of charcoal can be affected, while secondary Product species can roll up, and cause the difficulty that reclaims and classify.
Compared with prior art, the present invention has advantages below：Biomass to being pyrolyzed carry out prior the pre-heat treatment, discharge Moisture in biomass, improves pyrolysis charring effect, and the moisture to discharging carries out condensation process, free from environmental pollution and be not required to another It is equipped with raw material drying apparatus.
Specific embodiment
Describe the present invention with reference to embodiment, the description of this part be only it is exemplary and explanatory, no Reply protection scope of the present invention has any restriction effect.
Embodiment 1
A kind of biomass carbonated preprocessing process, including procedure below：By biomass in 270 DEG C of heating, vapor is discharged.
Further, the vapor to discharging carries out condensation process, obtains condensed water.
Embodiment 2
A kind of biomass carbonated preprocessing process, including procedure below：By biomass in 280 DEG C of heating, vapor is discharged.
Vapor to discharging carries out condensation process, obtains condensed water.
Embodiment 3
A kind of biomass carbonated preprocessing process, including procedure below：By biomass in 275 DEG C of heating, vapor is discharged.
Vapor to discharging carries out condensation process, obtains condensed water.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should It is considered as protection scope of the present invention.
