High-temperature harmless treatment method for kitchen waste

Abstract

The invention discloses a high-temperature harmless treatment method for kitchen waste. The high-temperature harmless treatment method for kitchen waste comprises collection and solid-liquid separation of kitchen waste, solid-liquid separation and classification screening of kitchen waste, crushing treatment of recyclable solid waste, oil refining, separation of oil residues, filtration and collection of oil, pressing and packaging of residues, purification and recycling of waste water, waste gas treatment, and solid waste treatment. The high-temperature harmless treatment method for kitchen waste utilizes the technologies such as PLC (Programmable Logic Controller) automatic control, an assembly line type extraction technology, a heat conduction oil repeated circulation technology, boilerconcurrent heating, fully enclosed type high-temperature sterilization, zero-pressure production, waste gas and waste water purification treatment in a combination manner, and achieves the harmless,reduction and resourceful treatment of kitchen waste. Compared with other domestic technologies, the high-temperature harmless treatment method for kitchen waste has the characteristics of low cost, efficient treatment, environmental protection and safety, low energy consumption, and turning waste into treasure.

Description

Technical field:

[0001] The invention relates to the technical field of kitchen waste treatment and recycling, in particular to a high-temperature method for harmless treatment of kitchen waste. Background technique:

[0002] Kitchen waste is the most common waste generated in people's daily life. It belongs to the main urban domestic waste. Its main components include organic matter such as starchy food, plant fiber, animal protein and fat. High content, perishable and smelly, not conducive to the transportation of ordinary garbage trucks, etc. If this kind of waste is not treated by special classification, it will cause great harm to the environment.

[0003] Kitchen waste mainly comes from food processing leftovers (meal waste) and use residues produced by the catering service industry, family and unit canteens. With the rapid development of my country's economy and the gradual acceleration of urbanization, the amount of kitchen waste The production is showing an increasi...

Embodiment 1

[0057] The high-temperature French method for harmless treatment of kitchen waste includes ① collection of kitchen waste and solid-liquid separation: after the kitchen waste is produced, it is collected in standard collection barrels by hotels, canteens, etc. , and then uniformly collected by the kitchen waste collection truck, the thrown waste is squeezed by a powerful push plate to achieve preliminary solid-liquid separation, the separated liquid enters the liquid storage part at the bottom of the tank, and the solid waste is compressed Stored in the tank, the volume becomes smaller. After repeated filling, it is sent to the food waste recycling plant. All operations on the vehicle are hydraulic automatic control, which can be operated separately in the cab and beside the vehicle;

[0058] ② Solid-liquid separation, sorting and screening of kitchen waste: transport the kitchen waste collected by the kitchen waste collection vehicle to the sorting and screening workshop, open ...

Embodiment 2

[0077] The harmless treatment method of kitchen waste of the present invention is realized by the following equipment: the equipment includes: kitchen waste collection vehicle 1, kitchen waste vibration screening machine 2, crushing conveyor 3, oil refining device 4, oil residue Separation device 5 , grease collection device 6 , residue press packaging machine 7 , waste water purification and circulation device 8 , waste gas treatment device 9 .

[0078] Kitchen waste collection vehicle 1 is used for unified collection and first solid-liquid separation of kitchen waste;

[0079] The kitchen waste vibrating screening machine 2 is used to screen the non-recyclable solid waste and recyclable solid waste in the kitchen waste through the filter screen according to the volume of the solid waste after the first solid-liquid separation , the liquid waste after the solid-liquid separation is passed through the filter screen for the second solid-liquid separation;
