According to the "Medium and Long-Term Development Plan for Renewable Energy", by 2020, the total annual utilization of biogas in my country will reach 44 billion m3. While the biogas project consumes organic waste and produces clean energy, it also produces a large amount of anaerobic digestion residues. Material - biogas residue and biogas slurry. Especially in some large and medium-sized aquaculture biogas projects, the amount of biogas slurry produced every day can reach hundreds of thousands of tons. If these biogas slurry and biogas slurry are not properly disposed of, it will not only waste resources, but also harm the air, Soil and water bodies cause secondary pollution. Biochar, pyrolysis oil and pyrolysis gas can be obtained by drying the biogas residue obtained by centrifugation and then pyrolysis. As the pyrolysis temperature increases, the carbon yield gradually decreases and the gas yield gradually increases. Biogas residue pyrolysis is a waste recycling and harmless treatment process.
☆Advantages of anaerobic fermentation by-product pyrolysis treatment system
★ Realized waste reduction and recycling
★ Emissions are environmentally friendly and environmentally friendly
★ Biochar can effectively adsorb harmful substances and ammonia nitrogen in biogas slurry
★ Can transfer 80% of energy to biochar, pyrolysis oil and raw pyrolysis gas
★ It has a wide range of applications and can be used for pyrolysis of different anaerobic fermentation by-products.
