High temperature aerobic fermentation equipment for kitchen waste

High temperature aerobic fermentation equipment for kitchen wasteBy rotating the cylinder itself, the material inside the cylinder is horizontally pushed and repeatedly rotated and stirred to achieve the purpose of material degradation and fermentation. Specifically, a push plate is installed inside the cylinder, which is fixed at a set angle inside the cylinder. The cylinder is driven to rotate around its own axis by a power device, and during the rotation process, the cylinder drives the push plate to rotate; When the push plate rotates, due to the angle between the surface of the push plate and the centerline of the cylinder, the push plate can push the material from the feeding port to the discharging port. At the same time, the material rotates together with the cylinder, achieving more uniform contact between the material and oxygen, and increasing the degradation of the material. At the same time, during the degradation process of the material, a large amount of oxygen needs to be introduced. The inlet of the fermentation cylinder is set at one end of the outlet of the cylinder. After the gas enters, it directly contacts the main fermented material, causing the biological bacteria to proliferate in an explosive manner. A large number of biological bacteria quickly decompose the material into various organic components and generate heat and water. The heat generated not only further heats up the main fermentation stage, but also heats up and humidifies the new material entering the inlet as the gas enters the inlet, promoting bacterial growth and providing better conditions for the main fermentation stage. Furthermore, the exhaust port is set at one end of the feeding port of the cylinder to facilitate the collection of exhaust gas generated during the fermentation process, avoid air pollution caused by exhaust gas leakage, and not affect people's lives. Its structure is simple and reasonable, with low energy consumption. During the fermentation process of kitchen waste, the degradation efficiency of organic matter is high, the degradation effect is good, and the fertilizer efficiency is high, making it suitable for large-scale promotion. The large amount of heat generated during the fermentation process is effectively utilized, saving resources. Compared with the main fermentation stage of existing technology, which mainly relies on continuous heating, stirring, drying, and partial carbonization, the energy utilization rate is high, the energy distribution is more reasonable, and does not require a large amount of electricity consumption. The fermentation method of existing technology consumes over 500 kWh of electricity per ton of kitchen waste, resulting in high processing costs and no practical value; And drum typeHigh temperature aerobic fermentation equipment for kitchen wasteBy comprehensively utilizing the heat generated by biological aerobic fermentation without the need for heating devices, the energy consumption is 14 kWh/ton, saving over 95% of energy. After the exhaust system discharges the exhaust gas, it is collected and purified by a purification device. The purified exhaust gas can be discharged into the air without polluting the environment.
