Development and research of a three-phase induction device for heating and mixing liquids

Abstract


The questions of the development of design and operating parameters of a three-phase induction device combining the functions of heating and mixing viscous liquids, in particular oil and viscous oil products, are considered. Specific features of the process of transporting viscous fluids through pipelines are noted. It is shown that the high viscosity of the pumped fluids leads to high energy costs. One way to reduce energy consumption is to heat the liquid before transporting it. To increase the intensity of heat transfer between the pipe wall and the heated fluid stream, an induction device built into the pipeline system is proposed that simultaneously performs the function of driving the rotation of the mixer wheel and the heating device. The results of a numerical calculation of the electrical parameters of the device are presented. It is shown that the power supplied to the inductor is distributed into two flows - the power of internal heat generation in the rotor wall and the power of rotation of the rotor. The relationship between the thermal energy released in the rotor wall and the energy used to rotate the rotor on the frequency of rotation of the inductor field is established. Calculations showed that an increase in frequency leads to an increase in the fraction of power for heating, and a decrease in frequency leads to an increase in torque. The resulting conclusion allows you to use the frequency to select the effective mode of operation of the mixer. The proposed device is advisable to use in multi-section heating systems in order to optimize the design and operating parameters of a multi-section heater.
