The Benefits of Using Chicken Manure Biogas for Power Generation

Greenhouse Gas Emission Reduction: Biogas power generation from chicken manure can reduce greenhouse gas emissions by 80,000 tons annually.
Biogas Slurry and Residue: Liquid fertilizer and organic fertilizer.
Utilization of Generator Waste Heat: The waste heat from flue gas (550°C) is recovered to generate high-value steam, which is used to increase the temperature of the secondary pre-treatment pool, ensuring the activity of acid-producing bacteria. The waste heat from cooling the generator cylinder jackets and lubricating oil, recovered in the form of 90°C hot water, is used for the circulation and heating of the anaerobic fermenter spiral heating pipes.

Raw Material Collection: A traction-type ground scraper removes chicken manure and transports it to the power plant (twice daily). Underground sewage pipes directly transport sewage to the power plant.
Primary Treatment: Removal of debris from chicken manure and sewage.
Secondary Treatment: Hydrolytic acid-producing bacteria separate the sand from the chicken manure; optimal working conditions are: temperature 30°C~35°C, pH value: 6.0~6.5, reaction time: 6 hours.
Anaerobic Fermentation: The slurry with a solid content of 8% is sequentially sent to primary, secondary, and tertiary anaerobic fermentation tanks for fermentation. Optimal working conditions: corrosion-resistant, well-sealed Lepu tanks, temperature: 35°C~38°C (in northern winters, fermentation temperature is increased by circulating the generator's cylinder jacket water through spiral heating pipes), pH value: 8~8.5.
Biological Desulfurization: Reduces hydrogen sulfide content to below 300 ppm.
Biogas Storage: Uses double-layer membrane dry gas storage tanks (utilizing blowers and safety valves to maintain constant biogas outlet pressure).
Chicken Manure Biogas Power Generation: Employing chicken manure biogas gas-powered generators, where the biogas burns in the engine cylinder to perform work, driving the piston movement. The piston's movement drives the engine crankshaft, which in turn drives the generator connecting rod to cut through magnetic field lines to generate electricity.
