Emulsified biodiesel preparation device

Abstract

The invention provides an emulsified biodiesel preparation device. The emulsified biodiesel preparation device comprises a liquid-liquid electrostatic dispersion device, a square column, four rib plates, electrode plates, one or more porous nozzle sets, a high-voltage electrostatic generator, a dispersed phase liquid storage tank, and a continuous phase liquid storage tank; the liquid-liquid electrostatic dispersion device is provided with a flow guiding section, an emulsifying section and an outflow section; the square column is arranged in the emulsifying section; the four rib plates are connected with the side edges of the square column and the inner wall of the emulsifying section correspondingly; the electrode plates are arranged on the four side faces of the square column; the one ormore porous nozzle sets are arranged on the side faces of the emulsifying section and each provided with four porous nozzles which are evenly distributed in the circumferential direction, and the porous nozzles are submerged in continuous phase liquid; the high-voltage electrostatic generator is connected with the porous nozzles; the dispersed phase liquid storage tank is connected with the porous nozzles; and the continuous phase liquid storage tank is connected with a flow guiding inlet. According to the emulsified biodiesel preparation device, charged dispersed phase liquid is atomized through the porous nozzles and then sprayed to the electrode plates, thus symmetrical annular flowing is formed, and dispersed phase liquid droplets are formed and evenly dispersed in the continuous phase liquid, and the emulsified biodiesel preparation device does not need any emulsifier and co-emulsifier or any stirring device, and has the general applicability on to the dispersed phase liquid withthe different density.

Description

technical field [0001] The invention relates to the field of biodiesel emulsification, in particular to an emulsified biodiesel preparation device. Background technique [0002] With the gradual depletion of petroleum resources and the increasing environmental pollution caused by fuel combustion, countries all over the world have begun to devote themselves to the development of renewable and environmentally friendly alternative fuels to save energy and alleviate the environmental crisis. [0003] Compared with petrochemical diesel, burning biodiesel can significantly reduce the emission of carbon monoxide CO, hydrocarbon HC and particulate matter PM10, but the disadvantage is that the emission of nitrogen oxides NOx has increased. Nitrogen oxides participate in the destruction of the ozone layer and are also one of the main causes of acid rain and photochemical smog. Reducing nitrogen oxide emissions has become a major research direction in the international environmental pr...

Ionic surfactants contain sulfur, which often form sulfides after combustion and increase air pollution. The cost of non-ionic surfactants Span and Tween series is expensive, and the compounding process of emulsifiers is complicated. These reasons make emulsified biodiesel widely used Limited, in the prior art, static electricity is used to atomize distilled water to form small droplets and then sink into diesel oil to form emulsified diesel oil, trying to reduce the amount of emulsifier, but the emulsification process still needs to be stirred with a magnetic stirrer, requiring a variety of emulsifiers and Co-emulsifiers are difficult to compound and used in large quantities. Therefore, the role of static electricity in the prior art is limited, and the generation of micro-emulsified diesel oil relies more on the traditional stirring method and the addition of various emulsifiers
