The invention belongs to the technical field of biomass pyrolysis and discloses a device for continuously pyrolyzing biomass all day by solar energy. The device comprises a condenser, a reactor, a low-temperature molten salt tank, a high-temperature molten salt tank and a product collector, wherein the condenser reflects energy of sunlight and transmits the energy to the reactor to increase the temperature, and to-be-pyrolyzed biomass enters the reactor for a pyrolytic reaction; a molten salt pipeline with two ends connected with the low-temperature molten salt tank and the high-temperature molten salt tank is arranged on a central shaft of the reactor, when the sunlight is sufficient, low-temperature molten salt enter the molten salt pipeline to absorb heat in the reactor to form high-temperature molten salt so as to store solar energy; when the sunlight is insufficient, high-temperature molten salt in the high-temperature molten salt releases heat for pyrolysis of biomass, so that the to-be-pyrolyzed biomass is pyrolyzed continuously all day. The biomass is heated by solar energy continuously all day to be subjected to pyrolytic reactions, and the device is green, environmentallyfriendly and pollution-free.
Description
technical field [0001] The invention belongs to the technical field of biomass pyrolysis, and more particularly relates to a device for uninterrupted pyrolysis of biomass using solar energy throughout the day. Background technique [0002] Solar energy has been paid special attention because of its renewable, wide distribution, huge reserves, and simple utilization. Since solar energy belongs to radiant energy and has the characteristics of instantaneousness, it cannot guarantee the continuous and stable output of solar energy. In order to overcome the shortcoming of the instantaneous nature of solar energy, solar energy utilization technologies often need to be used in conjunction with energy storage devices or to convert solar energy into chemical energy and store it. [0003] Biomass is an important renewable energy with the characteristics of green, low-carbon, clean, and the only renewable carbon source. However, due to its low energy density, the utilization efficien...
