Kitchen waste oil-water-solid separation device of kitchen waste

Abstract

The invention discloses a kitchen waste oil-water-solid separation device consisting of a steam mixing section, a solid-liquid separation section and an oil-water separation section, wherein the steam mixing section is provided with a steam-water mixer; high-temperature steam is input from the steam inlet of the steam-water mixer; the absorption inlet of the steam-water mixer is communicated with a slag-liquid mixing groove; the injection port of the steam-water mixer is communicated with the input end of a solid-liquid separation machine; and the liquid exhaust port of the solid-liquid separation machine exhausts to an oil-water separator. According to the invention, the steam-water mixer for heating directly on a pipeline mixes high-temperature steam in crushing slag liquids, not only can the operation continuity be ensured, but also the whole treatment can be operated in a production line, continuity and scale mode, and moreover, mixed liquids output from the injection port has high temperature and high pressure, and enter the solid-liquid separator directly for solid-liquid separation, and additional delivery equipment is not required; and the efficiency is high, and the separation quality is good.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an oil-water-solid separation device for kitchen waste. Background technique [0002] The dual attributes of hazard and resource coexist in kitchen waste. On the one hand, kitchen waste has a high oil-water content, generally 80% to 90%. It is perishable and produces stench. Improper disposal (landfill or incineration) will cause serious environmental pollution; and the sources are complex, including viruses, pathogenic bacteria, Pathogenic microorganisms can also cause the spread and infection of pathogenic bacteria, which are more harmful. At the same time, kitchen waste is mainly composed of meal leftovers and kitchen waste, with starch, dietary fiber, animal and vegetable oils, fats and other organic substances as the main components, such as meat, fish, fruits, vegetables, Cereals, bones, processed foods, etc. are characterized by high organic matter conte...

Problems solved by technology

This technology not only requires a large container to stratify the kitchen waste, which takes up a large area and takes a long time; moreover, the separation effect is not thorough enough, and the oil yield is low, especially for the northern regions with severe winter climate, where the oil is easily Solidification freezes on a solid surface, making it difficult to separate

In the Chinese patents "201120365212.1---a kitchen waste oil-water separation device" and "201110115100.5---a kitchen waste oil-water separation treatment method", methods such as heating oil heat exchange and steam heating are used to overcome the severe cold and low temperature factors. However, the processing time is still very long, which cannot meet the needs of large-scale continuous processing operations, and also affects the promotion of industrialized processing technology for kitchen waste
