Abstract

A system for cyclic use of biomass resource is composed of a fermenting unit consisting of filling tank and multi-stage fermenting pool, a fuel battery unit with negative electrode connected via desulfurizer to H2 and methane discharging outlet of fermenting pool, a soilless culture unit connected to residual liquid discharging outlet of fermenting pool and the CO2 discharging outlet of fuel battery unit, and a granulating machine connected to the residual dreg discharging outlet of fermenting pool.

Description

technical field [0001] The invention relates to a technology for comprehensive utilization of biomass waste, and more specifically, the invention relates to a system for recycling and utilizing biomass resources. Background technique [0002] The utilization of biomass waste has many specific applications, which can be generally summarized as energy utilization and resource utilization of biomass waste. Among them, the energy utilization of biomass waste is the mainstream of research at home and abroad, but the resource utilization of biomass waste has not yet formed a scale. [0003] (1) Energy utilization of biomass waste [0004] In terms of biomass energy utilization, the biogas power generation technology that converts biomass waste into electricity and heat energy through anaerobic fermentation to obtain biogas has become a representative research direction. Biogas power generation technology can be roughly divided into two categories: one is to obtain electricity th...
