company news about High Temperature Aerobic Organic Fertilizer Compost Fermentation Tank

Vertical fermentation tank
The vertical fermentation tank mainly conducts high-temperature aerobic fermentation of livestock and poultry manure, kitchen waste, domestic sludge and other wastes, and uses the activity of microorganisms to decompose the organic matter in the waste to achieve harmlessness and stability. Integrated sludge treatment equipment for reduction and resource utilization. The working principle of the equipment is to mix the waste (livestock and poultry manure, kitchen waste, domestic sludge, etc.), biomass (straw and sawdust, etc.) and return materials in acertain proportion, so that the moisture content reaches the design requirement of 60-65%. Entering the three-dimensional aerobic system, by adjusting the moisture oxygen content and temperature changes of the raw materials, the materials are fully decomposed by aerobic fermentation. The heat released during the decomposition process can increase the temperature of the sludge itself, and the temperature can reach up to 80 ℃. As the temperature rises, the water in the mud is evaporated, and part of the organic matter is decomposed, thereby reducing the volume of the pile and achieving the reduction of waste. The organic fertilizer fermentation tank controls the temperature between 55 and 60 °C through ventilation, oxygenation, stirring, etc.,to achieve the best temperature for material fermentation treatment. At this temperature, a large number of pathogenic bacteria and parasites in the heap can be killed. At the same time, the deodorization system is used to carry out biological odor to the exhaust gas to achieve the purpose of harmless treatment. The product obtained after high temperature aerobic fermentation can be used for soil improvement, landscaping, landfill cover soil, etc.
The whole equipment mechanism is divided into three parts, the lower base part is distributed with hydraulic station, vortex air pump, oil cylinder, heating system and stirring shaft; It is lined with 304 stainless steel plate, the middle interlayer is filled with polyurethane foaming agent, and the outer wall is made of thickened steel plate to support the tank body; Ancillary equipment includes automatic tipping bucket elevator, exhaust gas filtration and deodorization system and heat exchange system device.

Working principle
The fermentation tank is a biological fermentation system that feeds from the top and discharges the decomposed materials from the bottom. The sludge is added from the top of the tank and stirred by the internal stirring blades. The stirring blades have a high-pressure fan for forced ventilation and oxygen supply, and the materials in the tank are good. oxygen fermentation. The ventilation system allows the air to pass through the material from the bottom of the fermentation tank, and after being collected in the upper part of the fermentation tank, the exhaust gas is treated by the deodorization system and discharged up to the standard. The effect of high-temperature aerobic bacteria makes the fermentation temperature reach 60-70 degrees, fully kills various pathogenic bacteria, evaporates the moisture in the sludge,and converts organic wastes such as sludge into organic nutrients. A single device can process 5-10 tons of fresh sludge with a moisture content of 60-80%, the fermentationperiod is about 7 days, and the moisture content of the organic material after fermentation is about 30%.

Features:
1. The structure design is very user-friendly and easy to operate. Smooth transmission

and low noise.
2. Appropriate diameter-to-height ratio design, customized stirring device on

demand, energy saving, good stirring and fermentation effect.
3. The surface of the inner tank body is mirror polished (roughness Ra≤0.4μm); the

process openings such as inlet and outlet nozzles, sight glasses, manholes and the

welding of the inner tank body adopt the arc transition of the stretching flanging

process, which is smooth and smooth. Easy to clean and no dead ends, to ensure the

reliability and stability of the production process, in line with "cGMP" and other

specifications.
