Biomass gasification and carbonization treatment method and integrated device

Abstract

The invention discloses a biomass gasification and carbonization treatment method and an integrated device. The biomass gasification and carbonization treatment method comprises the following steps: S1. arranging a gasification furnace, a carbonization furnace, a separator, a stock returning device, a cyclone separator, a bag-type dust collector and a cooling device; S2. burning a biomass raw material through the gasification furnace; S3. separating burnt biomass through the separator, so as to obtain high-temperature flue gas and incomplete-burnt biomass; S4. extracting part of the high-temperature flue gas, and mixing the extracted high-temperature flue gas with air, so as to obtain fluidized air; S5. returning the incomplete-burnt biomass into the gasification furnace for re-combustionthrough the stock returning device; S6. dedusting the high-temperature flue gas through the cyclone separator; S7. subjecting the dedusted high-temperature flue gas to oxygen-deficient cracking gasification in the carbonization furnace, so as to obtain fixed carbon and combustible gas; S8. dedusting the combustible gas through the bag-type dust collector, so as to obtain clean combustible gas; S9.cooling the fixed carbon through the cooling device, thereby obtaining available fixed carbon. According to the biomass gasification and carbonization treatment method and the integrated device, theutilization ratio of the biomass raw material is effectively increased, and large-scale and continuous production can be achieved.

Description

[0001] method field [0002] The invention belongs to a biomass treatment method, in particular to a biomass gasification and carbonization treatment method. Background technique [0003] Energy is the material basis for human survival and the basic support of the national economy. my country is a big energy consumption country. The current energy supply mainly relies on fossil energy such as coal, oil and natural gas. However, the limitation of fossil energy resources and the huge pressure on the environment and ecology caused by the development and utilization process seriously restrict the sustainable development of the economy and society. At the same time, my country is a large agricultural country, and a large amount of plant biomass such as crop stalks, livestock and poultry manure, agricultural product processing by-products and energy crops are produced every year. Biomass gasification technology uses plant biomass as raw material, adopts pyrolysis method and thermo...
