Abstract

The invention relates to a device and method for pressing biomass particles by utilizing fermented biogas residues, and aims to solve the problems that effective utilization of massive straws of current peasant households is hard to achieve, and biomass residues after straws are utilized for biogas fermentation cannot be effectively recycled. The method for pressing biomass particles by utilizing fermented biomass residues comprises the following steps: conveying straws to a pulverizer by virtue of a conveying pipe; pulverizing straws into straw powder, and conveying the straw powder to a fermentation tank; fermenting the straw powder in the fermentation tank to generate methane, and filtering the straw powder which is fermented in the fermentation tank to generate biogas residues; detecting the moisture content of the biogas residues by utilizing a moisture content meter, adding straw powder into the biogas residues if the moisture content is higher than a set threshold value until the moisture content is lower or equal to the set threshold value; and conveying the biogas residues to a granulator by virtue of the conveying pipe, and pressing the biogas residues into straw particles. The device and method can be applied to straw application in the agricultural industry.

Description

technical field [0001] The invention relates to a device for pressing biomass granules by using fermented biogas residue and a method for pressing biomass granules. Background technique [0002] At present, straw resources in rural areas are extremely rich, and straws are mainly disposed of by low-efficiency and extensive combustion, resulting in great energy waste and environmental pollution. The development of straw fermentation biogas production and biomass straw granulation technology provides two efficient energy utilization approaches for straw treatment. [0003] The ideal use of the biogas residue produced by straw fermentation is to sprinkle it on the farmland as a fertilizer, but the biogas residue just out of the pond cannot be applied to the farmland immediately, and generally needs to be stacked for 5-7 days before application. Before use, it needs to be blended with water, applied in furrows and holes, and then covered with soil. Insufficient biogas residue m...
