The invention provides a cascaded excrement rapid resource utilization device for hydrothermal carbonization using ship waste heat, and belongs to the technical field of ship excrement resource utilization. The device includes a feed unit, a hydrothermal carbonization unit, a waste heat cascade utilization unit, and a hydrothermal product collection unit. The feed unit, hydrothermal carbonization unit, waste heat cascade utilization unit, and hydrothermal product collection unit are connected in sequence. The sewage intercepting backboard can adjust the proportion of feces and urine in the feces, effectively meeting the rough sailing conditions of the ship. The device obtains high calorific value hydrothermal charcoal and liquid by subjecting manure to hydrothermal carbonization reaction, which has the advantages of miniaturization of the device, small footprint, high degree of automation, adaptability to navigation conditions, and high processing efficiency; the hydrothermal charcoal prepared by it can be As high-quality fuel, biochar fertilizer, etc.; the liquid prepared by it can be used as liquid fertilizer, and can also be used as a supplementary carbon source for denitrification of ship domestic sewage treatment equipment.
Description
technical field [0001] The invention relates to the technical field of ship manure recycling, in particular to a manure rapid recycling device that utilizes ship waste heat for hydrothermal carbonization. Background technique [0002] The human navigation industry and ocean development have achieved unprecedented development. More than 90% of the world trade transportation volume is borne by shipping: ship manure (feces and urine), as a mobile pollution source, is one of the main sources of water pollution. With the continuous increase of the number of ships, the water environment pollution caused by their random discharge is becoming more and more serious. After the nutrients in the ship's domestic sewage enter the water environment, even if the content is 0.01 mg / L, it can cause excessive growth and reproduction of algae, cause eutrophication of the water body, reduce the content of dissolved oxygen in the water, and lead to marine animals and plants. Aerobic groups (like...
