Modern requirements for heat-exchange equipment. Constructive evolution of vortex spraying devices

Abstract

The paper deals with the modern requirements of a new technology. Indicate the direction of the development of science and technology on the problem of heat and mass transfer. Due to the sharp rise in price of energy in the world and a deficit of water resources modern heat and mass transfer devices shall meet the requirements such as: energy-intensive, highly efficient and intensive, to be universal, simple to constructively and to provide convenience of installation and operation. The possibility of combining and intensifying physical and chemical processes in gas-liquid systems due to the creation of a developed turbulent phase movement in one apparatus allows us to achieve high efficiency of mass transfer and gas purification. Despite the fact that the construction of hollow vortex spray devices have been developed for a long time, they did not find until recently widespread use for a number of reasons, among which should be noted as deficient researched description of their work and the lack of scientifically grounded methods of calculation and disinterest of enterprises in qualitative clearing of industrial gas emissions. Based on the experience of use industrial vortex equipment, the main requirements for the design of new heat and power equipment have been developed and the possibility of creating such equipment, which meets the proposed criteria, is shown. Based on the above it can be argued that further research aimed at a thorough study of issues related to the problem of complex processing technology and industrial waste gases and the choice and design of highly vortex heat and mass transfer equipment is relevant and make it possible to reduce the environmental impact. A new multistage design of the vortex apparatus is proposed.

Results of a Study of the Ammonia Absorption Efficiency by a Brinе in a Vortex Device

“…After analyzing the known designs of heat and mass transfer devices and contact devices [6,7], the task is to develop and justify a promising design of a highly efficient contact device that provides increased gas and liquid throughput with the least hydraulic resistance. A promising direction in the field of intensification of ammonia absorption processes are vortex devices [8].…”
