METHOD OF PURIFYING HIGH-TEMPERATURE AEROSOLS Russian patent published in 2018 - IPC B01D53/00 

FIELD: technological processes.

SUBSTANCE: invention relates to the purification of high-temperature aerosols from emissions of harmful substances (including solid particles and substances hazardous to the environment and humans) of industrial production. In the method of cleaning high-temperature aerosols from harmful substances in industrial emissions, carry out a multi-stage cleaning of high-temperature aerosols, at which produce at least one stage of purification of coarse aerosol from the dispersed phase with simultaneous controlled withdrawal of precipitated solid particles from the area of their separation, heat recuperation or recovery and coordinated single-stage or multi-stage reduction of the high temperature of the aerosol to the operating temperature for changing at the subsequent stages the chemical composition of the aerosol and the proportions of the content in the aerosol of its components in different state of aggregation and for the mechanical cleaning of the aerosols from the dispersed phase.

EFFECT: invention is aimed at improving the efficiency of the method and the quality of cleaning aerosols by achieving a deep degree of purification due to the agreement between the stages of purification of temperature regimes, volume and size of solid particles between the stages, which leads to a decrease in the cost of cleaning, reduction of dispersed phases in the atmosphere and their collection, as well as the continuity of cleaning and creating the necessary conditions for the effective cleaning of the aerosol from harmful chemical compounds.
