Treatment method of waste kitchen grease

Abstract

The invention provides a treatment method of waste kitchen grease. The method comprises the following steps of S001, screening and impurity removal, wherein collected waste kitchen grease is poured into a receiving device, and the waste kitchen grease passes through a screen net to be screened; S002, heating and melting, wherein screen underflows are heated, and the waste kitchen grease is heatedand molten; and S003, pipeline impurity removal, wherein the molten waste kitchen grease passes through a pipeline impurity removal device, and impurities in the waste kitchen grease can be removed; S004, heating and layering, wherein the waste kitchen grease is heated, and the waste kitchen grease is layered into an oil phase, a liquid phase and a slag phase after heating; and S005, centrifuginglayering, wherein the oil phase is guided into a three-phase centrifugal machine to be centrifuged, and a liquid phase, a slag phase and an oil phase meeting the biomass diesel oil standard can be met. According to the treatment method of the waste kitchen grease, the defects that existing waste kitchen grease treatment is large in manual intensity, low in treatment efficiency, simple in procedure, and poor in environment sanitation and oil quality are overcome.

Description

technical field [0001] The invention relates to the field of waste kitchen fats and oils, in particular to a processing method for waste kitchen fats and oils. Background technique [0002] With the improvement of people's living standards, people's diet has become more and more diversified, and the catering industry has become more and more developed, but it has also brought about great environmental problems. The catering industry will discharge a large amount of waste liquid, and these waste liquids contain a lot of oil, the so-called waste kitchen fat. The production of a large amount of waste kitchen grease will pollute the environment on the one hand, such as clogging the gutter and even stink; [0003] In order to eliminate the safety and environmental hazards caused by the above-mentioned waste kitchen fats and oils, more technologies are currently used to convert waste kitchen fats and oils into biodiesel. However, the waste kitchen fat needs to be refined before ...
