Multilevel-control polyradical biomass-gasification energy regeneration system

Abstract

The invention provides a multilevel-control free-polyradical biomass-gasification energy regeneration system, which can transform extensive biomass and carbon-containing raw materials, including energy crops, agriculture-forestry byproducts, organic waste, industrial and dangerous waste and the like, into high-grade energy. The system is designed for continuous operation. Gasification comprises the following steps of performing pretreatment, performing pyrolysis, transforming carbon, fusing ash, cracking tar, reforming syngas and utilizing waste heat, wherein the steps are precisely controlled one by one and integrated so as to achieve optimum; moisture from the pretreatment of the materials is led into a carbon-transforming unit so as to realize oxygen-free pyrolysis; gasification gas is in contact with a large number of free polyradicals in a free-polyradical reaction-accelerating unit; and the obtained product is purified and then enters downstream application, such as power generation, hydrogen production and biomass methanol / ethanol production. The system has the advantages of needing no auxiliary fuel, maximizing gasification efficiency and thoroughly cracking tar and clearing pollutants, and is an upstream technique for the application of biomass renewable energy. As energy utilization meets all strict environmental protection standards, the system is also an energy-saving environment-friendly technique for non-incineration harmless treatment.

Description

technical field

[0001] The invention relates to a biomass gasification renewable energy system, in particular to a biomass gasification renewable energy system utilizing a free radical acceleration reaction device. Background technique

[0002] Energy is the basis for the survival and development of modern society. The supply capacity of energy is closely related to the sustainable development of the national economy and is one of the foundations of national strategic security. China's current energy supply situation is grim, and the burden on environmental quality is heavy. Due to the dwindling reserves of fossil energy, large fluctuations in oil prices, concerns about energy security and global warming, the development of clean and renewable energy has become an urgent issue, and the new energy industry is showing high growth. According to the widely demonstrated industrial background and development overview of renewable energy, biomass gasification power generation repr...
