Preparation method and device of oxygen-enriched microemulsion mixed biodiesel

Abstract

The invention relates to a preparation method and a device of oxygen-enriched microemulsion biodiesel. The device comprises a housing, wherein the housing is internally equipped with a vertical stirrer; a power source drives the vertical stirrer to rotate; paddle-type straight stirring paddles or paddle-type folding-blade paddles are mounted on a middle shaft of the vertical stirrer; a turbine or a disc bending-blade paddle is mounted at the lower part of the middle shaft of the vertical stirrer; more than one feed port is formed at the top of the housing; each feed port is connected with a piece of quantitative feeding equipment by a pipeline; a finish product discharge port is formed at the lower part of the housing; and an oxygen-enriched water supply port is formed at the top of the housing. The method comprises the following steps of (1) inputting crude biodiesel into the device for the emulsification biodiesel, starting a stirring system, adding diesel meeting a national Grade III standard, stirring for 5 min, (2) adding a hydrophilc agent, stirring for 1-15 min, (3) adding butanol and isopentane, continuing to stirring a mixed liquid directly, and (4) adding the oxygen-enriched water, stirring for 15 min, standing for a certain time, observing that emulsified oil is clean, transparent and free from layering, and obtaining a finish product.

Description

technical field [0001] The invention discloses a production device and method of oxygen-enriched microemulsion mixed biodiesel, and more particularly relates to a kind of hybrid oil produced in the process of processing kitchen waste, which is converted into biodiesel and then further made into oxygen-enriched microemulsion mixed biodiesel. Method and device for producing biodiesel. Background technique [0002] In the process of food waste treatment, hybrid oil will inevitably be produced, which is a mixture of vegetable oil and animal oil. At present, many methods are to make fatty acid methyl ester fuel through esterification reaction, which can also be called pure biodiesel. Its physical and chemical The characteristics are close to petrochemical diesel, which is a typical renewable energy source. In order to make pure biodiesel closer to the characteristics of mineral diesel, a method of mixing with petrochemical diesel has been produced to make mixed biodiesel ...

[0002] In the process of food waste treatment, hybrid oil will inevitably be produced, which is a mixture of vegetable oil and animal oil. At present, many methods are to make fatty acid methyl ester fuel through esterification reaction, which can also be called pure biodiesel. Its physical and chemical The characteristics are close to petrochemical diesel, which is a typical renewable energy source. In order to make pure biodiesel closer to the characteristics of mineral diesel, a method of mixing with petrochemical diesel has been produced to make mixed biodiesel or micro-emulsion diesel, which is used as a fuel for boilers. Fuels and vehicle fuels, mixed biodiesel and microemulsion biomixed diesel have been found in the current application experience to reduce the emission of harmful substances such as soot, CO and HC, but there are also problems due to the low carbon-hydrogen ratio of fuel and oxygen-supported combustion. Insufficient fuel consumption leads to poor fuel combustion efficiency, carbon deposits on the intake and exhaust valves of engine cylinders, combustion chambers, intake pipes, and oxygen sensors, which increase fuel consumption, poor exhaust, and weak driving. The amount of air is used to meet the oxygen content of the engine, but 78% of the air is nitrogen that cannot support combustion, and only 20% is oxygen that can support combustion, which is not enough to change the combustion environment, but will increase NO X emissions
