Issues related to protection of the air basin from pollution by industrial and ventilation emissions, which is one of the most important problems of our time, study of the principles of sustainable nature management based on new effective methods and cleaning devices, improvement of existing gas cleaning equipment, search for solutions. problems of the industry and formation of the effective dust-cleaning equipment. Possible ways to improve the equipment for cleaning gases from dust by creating dust collectors, where the principles of operation of several devices are combined, are considered. This can not only increase the degree of cleaning, but also reduce the production area occupied by dust cleaning equipment, reduce energy costs for the cleaning process and thus reduce the cost of cleaning compared to using several separate devices, the principles of which are combined in this equipment. It is proposed to improve the dust collector while eliminating the shortcomings identified during testing and operation. It is shown that in order to use the obtained advantages in the improvement and creation of devices of other types it is necessary to develop scientific bases of creation of these devices, to develop methods of their experimental researches and processing of the received results. The ultimate goal of any design development is to reduce the cost of products with high quality. The existing methods of extracting dust particles from the stream are analyzed. Methods and equipment for dust collection are considered. The necessity of creating highly efficient devices for air purification from fine dust has been proved. The limits of influence of various factors on the processes of dust collection are revealed. The purpose of determining the application of existing dry methods in the field of dust extraction from the stream is considered. The analysis of existing methods of air purification from dust on the basis of modeling is carried out. The influence of air environment on particle motion is shown. The method of calculation of designs of development of highly effective dust-cleaning equipment and its successful practical operation is given.
