The content of R & D project implies in the significant improvement of purification quality of gas streams from polydisperse dust through the realization of separate purification principle and isolation of dusted stream from environment. Double effect closed system is designed for aspiration air purification from polydisperse dust on small enterprises and productions.
Environmental effect is achieved through separate purifying of dust masses with diverse fractional composition and through total isolation of system from environment. Technology does not require major investments.
The methodology of purification system design is developed, which allows to perform its design calculation and the calculation of the main indicators of purification quality. Documentation for patenting initiation is developed.
