Анализ процесса получения биодизельного горючего и обоснование основных параметров реактора-разделителя

The paper gives the results of a theoretical research on determining the main parameters of a reactor-divider for obtaining diesel fuel from vegetable oils. The hydro-station operation-regimes which provide minimum energy consumption for emulsion mixing have been determined. A number of experiments in three dimension plan of an isolation ward banquet in which the dependence between the power used for mixing, hydropump revolutions, and the diameter of a injector come has been determined. The optimal mixers parameters, which will provide a necessary reaction of methanolysis with a minimum energy consumption have been determined and given. The obtained biodiesel quality corresponds to the requirements of state standards of Ukraine 6081:2009 as to kinematic elasticity, density as well as to the flash temperature in a closed crucible. The biodiesel obtained can be used in diesel generators of tractors as well as in other mobile machines after some modernization. For non-modernized generators a part of volatile acids methyls in a mineral diesel fuel must not exceed 30%. It has been proved that the lowest indexes of power density of emulsion mixing while producing diesel biofuel in a circulating mixer-divider will range in diameter of an injector cone from 10 to 30mm and will reach minimum index of 9,8Ut/m3 Under a working volume of 50m3 in a circulating mixer-divider. A number of a hydropump revolutions and an injector cone diameter have an essential impact on an actual power, which is used for the emulsion mixing and circulating in a mixer. The angle of setting the injector doesn`t have any impact on energy consumption as well as on mixing and emulsion circulating. A consumed density in the range of hydropump revolutions from 800 to 1400 revolutions per minute considerably falls when the injector cone diameter ranges from 9 to 30mm; if the range is from200 to 800 revolutions per minute and the injector cone diameter ranges from 9 to 30mm, the consumed density remains practically same. The minimum energy consumption when mixing and emulsion circulating (0,15m3 in volume) in a circulating mixer CRPR-2 can be achieved under the hydropump P-100 revolutions frequency of 400 revolutions per minute and herewith sufficient emulsion mixing intensity is being provided.
