Title:
BIOMASS RADIATION-MICROWAVE COUPLED PYROLYSIS SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/016801
Kind Code:
A1
Abstract:
A biomass radiation-microwave coupled pyrolysis system and method. The system comprises a radiation pyrolysis apparatus (5) and a microwave pyrolysis system, which are arranged between a material feeding system and an oil-gas separation system, wherein the radiation pyrolysis apparatus (5) is of a sleeve shape and has an outer layer for flue gas to circulate therein and an inner layer for conveying and feeding a material, and an outlet of the radiation pyrolysis apparatus (5) is respectively connected to the oil-gas separation system and the microwave pyrolysis system; and the microwave pyrolysis system comprises a microwave pyrolysis apparatus (27) and a carbon condensation apparatus (23), an outlet of the microwave pyrolysis apparatus (27) respectively being connected to the carbon condensation apparatus (23) and the oil-gas separation system, the microwave pyrolysis apparatus (27) comprising a microwave generator (20) and a waveguide tube (25) arranged at the internal central axis thereof, and a wave feed port (26) being provided on the waveguide tube (25). In radiation pyrolysis, radiation heat transfer is carried out on biomass by using a high-temperature flue gas, such that carrier-gas-free pyrolysis is realized; and a microwave pyrolysis section can be directly connected, and a material in a fluidized bed (2) is further dried by using the flue gas which has been subjected to heat transfer, such that a gradient utilization of heat is realized.
