Technological Parameters for the Production of Selidition-Resistant Liquid Mixtures

All existing calculation methods involve finding the operating characteristics of dispersion, emulsification or homogenization. There are different ways to obtain emulsions and their further processing. Rotary-pulsation processing of dispersed systems in rotary-pulsation devices and impact-type pulsation dispersants is promising. The processes for preparing stable liquid water-oil fuels are one of the most energy-intensive processes in industry, which is associated with a significant overconsumption of heat and energy required for crushing the dispersed phase. To create dispersed systems, the most widely used method is mechanical crushing. It is possible to use dynamic effects when boiling droplets of small sizes to crush larger droplets. Almost every method of calculating the processes of crushing particles of the dispersed phase of an emulsion comes down to considering the main types of instability caused by the speed or acceleration of the flow. In this work, to crush particles of the dispersed phase, it is proposed to use a sharp release of pressure and the resulting sharp boiling of the thermolabile part of the emulsion (water). In this case, mechanical mixing devices are not used, and the crushing process itself involves particles of different sizes, which create various dynamic forces leading to the crushing of large particles by the forces acting from small particles when they boil. The paper describes the basic methodology for determining the technological parameters of the process of homogenization of emulsion media, at which it is possible to achieve the lowest energy consumption for carrying out the process itself and obtaining an emulsion resistant to separation. Conducted studies of the reuse of waste cutting fluids after technological production zones based on the developed new technologies for crushing the dispersed phase of emulsions have shown that with the design parameters for a hydrothermal emulsification apparatus determined using this method, it is possible to bring the dispersed composition of cutting fluids to the standard and, as a result, repeatedly return and use the used cutting fluids processed after each cycle.
