Abstract
The invention relates to the technical field of combustible gas preparation by virtue of biomass pyrolysis and gasification and further relates to the clean energy field of combustible gas preparation by virtue of pyrolysis and gasification of waste polymer compounds. The device consists of a gasification furnace, a plasma generation device, an oxygen-enriched combustion-supporting device, a biomass transporting device, a cyclone separation conveying device, a steam generation device, an air blower and a slag processing device, wherein the plasma generation device, an oxygen-enriched combustion-supporting pyrolysis region, a steam-adding thermalization reaction region and a second cracking region are arranged in a gasifying hearth; and multiple operation and control means are set, thereby conveniently regulating and controlling the furnace temperatures of various functional regions in the furnace to the optimal temperatures for gasifying the biomass or polymer compounds. By using the device, the generation of tar and K and Na metal salt gases can be avoided, thus the device provided by the invention is a combustible gas preparing device capable of improving the gasifying efficiency and the product quality, reducing the energy consumption and prolonging the service life of equipment.
Description
technical field [0001] The invention relates to the technical field of biomass pyrolysis and gasification to prepare combustible gas, and further relates to the field of clean energy for pyrolysis and gasification of waste polymer compounds to prepare combustible gas. Background technique [0002] With the decreasing reserves of traditional fossil energy (coal, oil, natural gas) and the environmental pollution caused by the use of fossil energy, the survival and development of human beings are directly threatened. Biomass is a kind of renewable energy with abundant reserves, which can be used as an alternative energy to achieve CO 2 Zero emission, and the content of S and N is low, which greatly reduces the greenhouse effect and environmental pollution. Recently, there are a lot of researches at home and abroad on biomass thermal cracking gasification to produce combustible gas, and the use of plasma technology in media gasification, natural gas cracking to produce acetylen...
