PARTITION DESIGN IN JET-FILM CONTACT DEVICES
In modern energy, chemical, petrochemical production, a cooling device is a necessary element of circulating water supply systems. The entire production, its energy efficiency, and durability rely on the efficiency of this device. Liquid cooling, which is observed in cooling towers using the evaporative effect, is considered an important process for most enterprises due to the fact that the specific energy consumption for water cooling is a large part of the total energy consumption. Currently, the most effective way to remove low-potential heat from the process equipment is the use of evaporative fan cooling towers. Despite its popularity, fan cooling towers have a number of drawbacks: they are energy-consuming and most of the existing devices have low liquid cooling performance. This is due to the fact that the contact surface of the liquid and gas phase has a small area, and the water does not have enough time to evaporate. A new design of jet-film contact device partitions has been developed, which allows increasing the liquid-gas contact surface and the overall efficiency of mass transfer. The main task in designing new type contact devices is to ensure high efficiency of water cooling with a fairly simple design. To study the flow of liquid through the partitions, we have developed an experimental unit and run a series of experiments on it. The paper considers necessary partitions with different radius of dislodged lobes and revels the dependence of the behavior of the fluid flow through the plates on the geometric dimensions of the lobe was determined. Studies have shown that the location of the flow source in relation to the first row of lobes has an important effect on the dynamics of fluid motion later. The use of this design for cooling the circulating water at industrial enterprises will significantly increase the efficiency of heat and mass transfer processes due to the large liquid and gas contact area and minimize the total water consumption.
