Comprehensive utilization system and comprehensive utilization method for biomass

Abstract

The invention discloses a comprehensive utilization system and a comprehensive utilization method for biomass. The comprehensive utilization system comprises a carbonization unit, a purification treatment unit, a gas mixing unit and a biomass charcoal recycling unit; and the comprehensive utilization method comprises the following steps: adding biomass raw materials into the carbonization unit, then, feeding air into the carbonization unit, controlling a carbonization temperature and an air flow for carbonizing and co-producing the biomass raw materials to obtain biomass gas and biomass charcoal; feeding the biomass gas obtained after carbonization into the purifying treatment unit, purifying the biomass gas to obtain purified biomass gas; mixing the obtained purified biomass gas with other combustible gases, conveying the mixed gas to users; and recycling the biomass charcoal obtained after carbonization. The comprehensive utilization system and the comprehensive utilization method for biomass, provided by the invention, develop and utilize agricultural and forestry wastes, realize comprehensive utilization of biomass, increase a utilization value and a conversion rate of the biomass raw materials, and improve the living environment of urban and rural residents.

Description

technical field [0001] The invention belongs to the technical field of biomass comprehensive utilization, and in particular relates to a biomass comprehensive utilization system and a comprehensive utilization method. Background technique [0002] At present, most regions in my country mainly adopt two methods to deal with agricultural and forestry wastes, that is, landfill in landfill or incineration. These two methods neither meet the requirements of environmental protection, but also waste money. Therefore, seeking harmless treatment and energy utilization of agricultural and forestry wastes is of great significance for saving natural resources, preventing environmental pollution, and realizing a virtuous circle of ecological economy. [0003] At present, the demand for natural gas consumption continues to be strong, and the new demand for "coal-to-gas" is released intensively. The peak-to-valley gap in some areas will be further widened. The situation is more serious. ...
