A POWER CALCULATION METHOD FOR SELF-SUCKING MIXERS

Sergey Shabratsky, Vitaliy Storogenko

Abstract


Most recently, in tank vessels designed for gas-liquid reactions, self-sucking mixers have been used as mixing devices. Great interest is the issue of mixing power determination of mixers designed for processes in gas-liquid systems, which can be an essential component in designing reaction vessels using effective mixing devices of self-sucking type for both liquid and gaseous phases. The efficiency of a mixing device is determined by evaluating the intensity of circulation of the mixed reaction mass, gas content and the ratio between the power consumption to create a gas-liquid medium and the total power consumption for mixing. In spite of a considerable number of publications on the determination of mixing power nowadays, there are no simple methods in existence for determination of mixing power of self-sucking mixers in vessels for gas-liquid reactions. For this reason, the mixing power calculation of self-sucking mixers for gas-liquid processes is an important part in the design of reaction vessels.
