The provided is energy storage method and device for biomass cascade pyrolysis coupled with new energy power generation. The key point of the technical solution is that, with inexpensive, clean and safe biomass as energy storage medium, the redundant unstable electric energy is converted by a cascade pyrolysis energy storage system into an easy-to-store liquid and solid chemical energy in biomass pyrolytic products, and based on use requirements, can be further converted into clean fuels for power generation or exported renewable chemicals, so as to realize continuous stable output of the new energy power generation systems. Furthermore, the cascade pyrolysis energy storage system can, based on the principle of 'energy level matching', fully recover and utilize the electric energy, high-temperature heat energy and low-temperature heat energy generated in pyrolysis processes, thereby maximizing the energy utilization efficiency of the system.

The present disclosure relates to a pyrolysis bio-oil fractional condensation device and method capable of cooling medium self-circulation. The device includes a primary condensation system, a secondary condensation system and a cooling medium self-regulation heat exchange system. The primary condensation system uses the temperature-regulated cooling medium to condense the macromolecular tar by direct heat exchange with the pyrolysis volatiles. The condensed tar is heated, pushed and scraped with a rotary mechanism to prevent adhesion. The spray liquid in the secondary condensation system exchange heat with the uncondensed volatiles directly for secondary condensation. The cooling medium self-regulation heat exchange system realizes self-circulation and self-balance of the cooling medium mass flow and energy flow by integrating heat absorption during biomass raw material feeding and drying, heat release during volatiles condensation, and heat absorption during pyrolysis char cooling, and realized the independent operation of the condensation device in the mobile biomass pyrolysis system.

A pyrolysis vapor outlet anti-coking device of adsorbing medium self-recycling regeneration includes a particle flow adsorbing system and a medium burning regeneration recycling system in mutual communication. The particle flow adsorbing system is configured to enable an easy-to-coke component to be adsorbed on an outer surface of an adsorbing medium to form a coking layer, and convey the a coking adsorbing medium into the medium burning regeneration recycling system. The medium burning regeneration recycling system is configured to quickly burn the coking layer on the outer surface of the adsorbing medium to realize regeneration of the adsorbing medium and convey the regenerated adsorbing medium into the particle flow adsorbing system for recycling use.
