INVESTIGATION INTO THE PROCESS OF INTERACTION OF THE LIQUID AND THE GAS IN A JET-FILM CONTACT DEVICE

With the aim of increasing the capacity of commercial cooling towers and enhancing heat-transfer processes, the authors have developed a structure of a jet-fi lm contact device. An experimental setup was assembled that permits investigating the hydrogasdynamics of a liquid in the operating region of the device. Results of investigation into the infl uence of the fl ow rate of the liquid and the gas on the hydraulic resistance of the contact device have been presented. A mathematical dependence has been obtained for calculating the pressure difference of a dry packing of the jet-fi lm contact device on the velocity factor. It has been established that with increase in the water concentration, the hydraulic resistance changes only slightly, which is a great advantage among the existing structures. The heat output of a cooling tower has been determined; the criterion of energy effi ciency has been considered which takes account of the expenditure of energy to pump air. The high energy effi ciency of a jet-fi lm contact device compared to various types of water-cooling devices has been proved
