Air pollution by dust of industrial origin since the beginning of the century has acquired the character of a technogenic catastrophe. At the same time, the deterioration of the ecological state of the air environment is clearly localized not only in industrial and transport areas, but also began to spread to cities, towns and recreation areas. The volumes of harmful emissions of suspended solids are hundreds of thousands of cubic meters, and only a non-waste part of them passes will be provided in the treatment facilities of enterprises. Due to the imperfection of technological and auxiliary treatment equipment, imperfection of technological processes of transshipment of bulk cargo, significant volumes of dusty air are formed in sea and river ports. At the same time, insufficiently high efficiency of polluted air purification leads to deterioration of cargo quality, excessive wear of equipment and a sharp deterioration of the environmental situation. One of the dominant factors in the formation of contaminated areas is the negative impact on human health. A wide range of methods and tools are used to combat dust pollution. Technical means are used to suppress dust with different physical and chemical properties, work in a wide range of temperatures and concentrations of pollutants. At the same time, due to the imperfection of the known structures and the insufficient development of the theoretical foundations of the processes, dust cleaners are unable to effectively capture small fractions of dust from the gas streams. In the current conditions, it became expedient to develop a new circuit solution of the modifier. the proposed rotary dust separator differs in that the housing comprises outlets and a cover in the upper part, a low-pressure flow nozzle and a high-pressure flow nozzle coaxial with the diffuser with blades, which is connected to the bearing housing and, separated from the bearings by a sealed seal.
