Abstract

The invention relates to a processing method of recycled illegal cooking oil, which comprises the following steps of: firstly, filtering impurities of collected illegal cooking oil, swilling oil and waste oil and depickling the collected illegal cooking oil, swilling oil and waste oil, then placing the collected illegal cooking oil, swilling oil and waste oil in an agitated reactor, adding 3-6% of carclazyte and 0.5-1.5% of phosphoric acid, mixing, heating and uniformly stirring, heating the uniformly stirred materials, naturally cooling to 34 DEG C-37 DEG C after settling and decomposing, filtering to obtain liquid oil and semi-solid carclazyte after settling and splitting phase, wherein the acid value of oil of the illegal cooking oil, swilling oil and waste oil is reduced from 3.5mg / koh / g to 0.9-1.4mg / koh / g, drying or naturally drying the semi-solid carclazyte in air, then placing the liquid oil and the semi-solid carclazyte in the agitated reactor, adding 3% of cation expression activity emulsifying agent, stirring at high speed for 20-50 minutes at the temperature of 50 DEG C-80 DEG C to enable fatty acid and triglyceride to be micro-emulsified, then adding 0.1% of ionic catalysis stabilizing agent, under the condition of 100-150Mpa pressure, and finally pumping hydrogen for 15-25 minutes by 0.5 per cubic meter per second to obtain biomass fuel. The processing method has the advantages of simple process, low cost, little energy consumption and high efficiency.

Description

technical field [0001] The invention relates to a treatment method for recovered waste oil. Background technique [0002] Our country has a large population, the consumption of vegetable oil and food is huge, and a large amount of catering waste is produced. In our country, catering waste can reach tens of millions of tons every day. Therefore, the developed catering industry in our country makes the output of catering oil extremely large, causing serious environmental pollution. . At the same time, problems such as the use of waste oil on the dining table and food waste to feed livestock have also arisen. At present, my country does not have a unified method to process or recycle waste oil. Contents of the invention [0003] The object of the present invention is to overcome the weak point that exists in the above-mentioned technology, and provides a kind of treatment method of recovering waste oil. [0004] In order to achieve the above object, the technical scheme ad...
