Purpose. Self-priming stirrers can be used in gas-liquid reactors for the processes of sulfonation of hydrocarbons with a gas reagent, chlorination, oxidation (ozonation) and at the stages of cleaning waste liquids from chemical contamination.
Application area. In the chemical and oil refining industry.
Advantages. Unlike known mixing devices, the developed designs use an energy conversion mechanism to ensure the suction of a gas reagent through the hollow channels of the stirrer, using the action of centrifugal force and the formation of a turbulent zone along the blades. The use of self-priming stirrers in industrial reactors allows, as a rule, to reduce the reaction time, increase the degree of conversion of the gas reagent and obtain a higher quality product, especially at low pressure of the gas reagent. This allows for a significant economic effect in real technological processes at minimal cost.
Description. Reactors with devices for dispersing gases in liquids used in the chemical and oil refining industries make it possible, in comparison with classical bubbling devices, to ensure a higher gas content in gas-liquid mixtures and high values of the mass transfer coefficient, as well as intensive circulation of the gas phase in volumetric devices.
