A biomass pyrolysis co-production method for pyrolysis oil reuse

Abstract

The invention discloses a biomass pyrolysis coproduction method for pyrolysis oil reuse, which includes a biomass pyrolysis coproduction process, a pyrolysis oil atomization combustion recovery process, and a solar drive process; the biomass pyrolysis coproduction process The pyrolysis oil produced in the process is recovered and stored in the pyrolysis oil storage tank; the pyrolysis oil in the pyrolysis oil storage tank is pressurized into the pyrolysis oil preheater, and enters the atomization after preheating chamber atomization, and provide thermal energy for the biomass pyrolysis coproduction process through burner combustion; the solar drive process provides a heat source to heat the pyrolysis oil to a set temperature; The heat provided by the preheater can enhance the fluidity of the pyrolysis oil, reduce the external energy consumed by heating the pyrolysis oil, and reduce the operating cost. At the same time, because the fluidity of the pyrolysis oil is improved, the atomization effect of the pyrolysis oil is solved Poor and unstable combustion recycling system, realized the direct and effective utilization of pyrolysis oil.
