Research Dispersing Liquid and Gas in the Contact Device with an Increased Range of Stable Operation

Abstract

To increase the efficiency of mass-transfer apparatus, a jet-bubbling contact device is suggested. The article considers perspectives for using of jet-bubble contact devices for heat and mass transfer apparatus. The distinctive feature of the developed device is an intensive countercurrent contact between the gas (vapor) and liquid in each element. The authors conducted experimental studies of dispersing liquid and gas in the proposed contact devices. Powerful turbulent axisymmetric perturbations occur in the bubbling layer, which affect the initial oscillations of the jet and determine the length of its decay. In the jets larger diameter distances between the involved gas bubbles less. Therefore, the resulting local jet are usually a smaller amount of liquid, which is decomposed accordingly into smaller drops.
