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.

Description

technical field [0001] The invention relates to the technical field of biomass pyrolysis, in particular to a biomass pyrolysis coproduction method for recycling pyrolysis oil. Background technique [0002] Biomass pyrolysis cogeneration is based on pyrolysis technology. Under the condition of isolating air or a small amount of air, biomass is used to cut off the chemical bonds in macromolecules by using heat energy to generate gas, liquid and solid small molecular substances; With carbonization technology as the core, various products such as pyrolysis gas, biochar, and tar are produced through solid gas, gas-liquid separation, and gas purification and upgrading. The product can be applied in many fields, effectively improving the comprehensive utilization efficiency of biomass. Pyrolysis gas is clean, environmentally friendly and renewable, and can be used as an important alternative energy source in rural areas. Biochar can be used as adsorption material, soil improver, ...
