Kitchen waste oil-water separation apparatus and oil-water separation method thereof

Abstract

The invention discloses a kitchen waste oil-water separation apparatus. The kitchen waste oil-water separation apparatus comprises a vertical tank body, wherein an oil-water interface measurement instrument, a temperature sensor, a rotating oil scraper and a waste oil collection groove are arranged inside the tank body; a waste water inlet and a waste gas outlet are formed in the top of the tank body; a steam inlet and a waste oil outlet communicated with the waste oil collection groove are formed in the bottom of the side wall of the tank body, a micro-bubble generator connected with the steam inlet is also arranged inside the tank body, and bubbles are generated from steam by virtue of the micro-bubble generator to enable an oil component of oil-containing compressed waste water in the tank body to float; the floating oil component is scraped by the rotating oil scraper into the waste oil collection groove and then discharged by virtue of the waste oil outlet; and the bottom of the tank body is provided with a water outlet valve, the oil-water separation apparatus is also provided with an automatic control mechanism, and the automatic control mechanism is respectively electrically connected with the oil-water interface measurement instrument, the temperature sensor and the micro-bubble generator so as to automatically control the oil-water separation. The invention also discloses a method for separating oil and water of kitchen wastes by utilizing the kitchen waste oil-water separation apparatus.

Description

technical field [0001] The invention relates to the field of separation devices, in particular to a kitchen waste oil-water separation device and an oil-water separation method thereof. Background technique [0002] With the rapid development of my country's social economy and the continuous improvement of people's living quality, the amount of kitchen waste is also increasing day by day. Most of them become kitchen waste and have not been effectively recycled, which not only seriously affects the urban environment but also causes serious damage Waste of resources and many food safety hazards, among which the food safety problems caused by kitchen waste oil (ie waste oil) are the most prominent. Slurry kitchen waste with extremely high water content can be separated and collected after the oil-water separation treatment, that is, the deoiling process is completed before it can enter the subsequent deep processing process. Therefore, oil-water separation treatment occupies a ...

AI Technical Summary

Problems solved by technology

Large pieces of solid animal fats (such as agglomerated tallow, etc.) that adhere to the surface of solid-phase kitchen waste are difficult to dissolve, so they cannot be formed into liquid oil to be put into subsequent deep processing links, thus making the kitchen waste Grease recycling rate is not high

And kitchen waste oil is mostly composed of fatty acid triglycerides, so it has stronger polarity than mineral oil, so it is more difficult to separate from water

[0004] At present, the existing oil-water separation devices and methods all focus on removing the oil in the water, rather than enriching the oil in the water

In addition, the separation effect of a single oil-water separation technology is generally low
