Abstract

The invention discloses a device and a method for preparing biodiesel. The device comprises a pipeline system, a reaction system and a measurement system, wherein the pipeline system comprises a raw material circulating storage box, a material circulating pump, an inflow pipeline, a return pipeline, an adjustable butterfly valve, and an unadjustable butterfly valve, the reaction system comprises a hydrodynamic cavitation reactor, a hydrodynamic cavitation porous plate, a striking room, and a motor driving rotating nozzle, and the measurement system comprises an upstream pressure gage and a downstream pressure gage as well as a flowmeter. Based on the coupling hydrodynamic cavitation and rotating impinging stream technologies, the device realizes efficient preparation of biodiesel. Circulating fluid flows through throttling holes in the porous plate inside the cavitation reactor, so that the cavitation phenomenon increases the turbulence intensity of the fluid, and the mass transfer area of an alcohol phase and an ester phase is greatly increased; the rotating impinging stream technology strengthens the tangential force in collision and enhances the cavitation effect on the collision surface; the device runs safely, has low running cost, can greatly improve the preparation efficiency of biodiesel, and shortens the preparation time of the biodiesel.

Description

technical field [0001] The invention patent relates to the fields of hydraulic cavitation and biodiesel preparation. In particular, it refers to a device and method for biodiesel preparation using hydraulic cavitation coupling rotating impinging flow technology. Background technique [0002] With the rapid development of our country's economy, especially the rapid development of the automobile industry, hundreds of millions of automobile exhaust emissions have brought worldwide environmental pollution, and the increasingly serious global energy shortage and environmental deterioration. Therefore, controlling the emission of automobile exhaust and protecting the natural environment on which human beings live have become urgent problems for human beings to solve. From the perspective of environmental protection and resource strategy, energy experts from all over the world are actively exploring and developing alternative fuels and renewable energy, which is of great significa...
