The invention relates to a
biomass waste resource
pyrolytic carbon gasification comprehensive conversion and utilization
system and a method employing the
system. In the
system, a
pyrolysis device is connected with a
gas supply device through a gas channel of a multifunctional heat exchange device, and is connected with a carbon
powder collection device through a pneumatic conveying device. A condensation
water channel is connected with a residual warmth heat supplying device through a
heat exchanger of the
pyrolysis device. According to the method,
mixed gas comprising
combustible gas,
tar gas, and
acetic acid gas is produced by high-temperature
pyrolysis of a
biomass raw material in the pyrolysis device, and carbon is also produced; the
mixed gas is absorbed into the multifunctional heat exchanging device and is subjected to heat exchange, and
combustible gas and a mixed liquid of
tar and
acetic acid are separated; water absorbs heat, and enters the
heat exchanger of the pyrolysis device, and heat exchange is continued, such that hot water is formed; hot water and
combustible gas are respectively delivered through the
gas supply device and the residual warmth heat supplying device, such that centralized
gas supply, heating, and hot water for residents are realized;
acetic acid can be used as a foliar
fertilizer or a
biocide, or can be mixed with carbon to form a bio-
fertilizer; and
tar is adopted as an industrial
raw material. With the system and the method, a
biomass waste resource conversion rate is approximately 100%.
