The invention relates to an integrated pretreatment system and method for kitchen waste. The system includes a material bin, a first screw conveyor, an extruder, a second screw conveyor, a residue pitsequentially arranged along the material conveying direction; and a liquid phase outlet of the extruder is in communication with a slurry tank, a solid phase outlet of the extruder is in communication with the inlet end of the second screw conveyor, the outlet end of the second screw conveyor is in communication with the residue pit, the slurry tank is in communication with a material inlet of athree-phase centrifuge through a delivery pump, a water phase outlet of the three-phase centrifuge is in communication with a concentrated water buffer tank, an oil phase outlet of the three-phase centrifuge is in communication with an oil inlet of a grease filter, a solid phase outlet of the three-phase centrifuge is in communication with a material inlet arranged in the middle of the second screw conveyor, and an oil outlet of the grease filter is in communication with an oil collecting tank. The system and method have the following beneficial effects: the pretreatment system and method havethe characteristics of a compact overall structure, a fast treatment speed, safe and convenient operation, a high degree of automation and easy installation and disassembly, and the system has a small floor space, basically does not need civil construction, has no location problem, and can be quickly built and put into use.
Description
technical field [0001] The invention belongs to the technical field of kitchen waste treatment, and in particular relates to an integrated kitchen waste pretreatment system and method. Background technique [0002] Kitchen waste is also called kitchen waste or wet waste. Kitchen waste refers to the waste generated in the daily life of residents and food processing, catering services, unit meals and other activities, including discarded vegetable leaves, leftovers, and leftovers. , peels, eggshells, tea dregs, bones, etc., the main sources of which are home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing. It is also the domestic waste formed by residents in the process of living consumption, which is extremely perishable, emits foul smell, and spreads bacteria and viruses. Its main characteristics are rich in organic matter, high in moisture content, and perishable. Its properties and odor will have a bad impact on enviro...
