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.

The article is devoted to the issues of reducing the negative impact on the environment of the production of soda ash, which is achieved by reducing the formation of gas and dust emissions, as well as their deeper cleaning. The problem of cleaning gas emissions from the production of soda ash is solved by using hollow vortex devices, their comparison with operating apparatus is given. The advantages of multi-stage vortex-type apparatuses for cleaning large volumes of industrial gas emissions are noted. The article states that the task of cleaning of industrial gas emissions is significantly complicated by their large volumes, which makes it difficult to use traditional treatment equipment. Most of the devices currently used to clean gases from gaseous, liquid and solid impurities are characterized by low throughput due to small maximum permissible gas velocities in the apparatus.The necessity of using multistage vortex devices for cleaning gas emissions from ammonia and soda dust is substantiated. The advantages of the apparatus of this group are noted -low hydraulic resistance, high efficiency and low energy and metal capacity. The comparison of vortex devices with other active gas cleaning devices according to fractional efficiency is given. The scheme of purification of gas emissions from soda dust, with its further utilization, is proposed. The efficiency of submicron particle deposition in a vortex apparatus with intensive phase interaction may exceed 95 %.

Object of research: vortex mass transfer device for the effective absorption of ammonia by brine in soda production. Investigated problem: intensification of mass transfer processes and ensuring effective absorption of ammonia with small dimensions of the device and low hydraulic resistance Main scientific results: studies of ammonia absorption efficiency in a laboratory device are carried out, which confirm the operability of the proposed device design. The dependences of the efficiency of the vortex device on the ammonia concentration and the brine consumption are revealed. The flow velocity and pressure in the device are simulated at various capacities. Scope of practical use of the research results: the research results can be used in the design of mass transfer equipment, primarily equipment for purifying emissions from ammonia and gas breakers from soda ash columns. Innovative technological product: the design of the vortex device, which allows achieving a high degree of absorption in ammonia with a concentration of up to 130 g/m3 of the order of 99 % at low operational (due to low hydraulic resistance) and capital (due to the compactness and small size of the installation) costs. Scope of the innovative technological product: the vortex device of the proposed design can be used to clean emissions, absorption of ammonia vapor or other mass transfer processes.
