FIELD: process engineering.
SUBSTANCE: invention relates to heat engineering and may be used for cleaning smoke fumes of harmful impurities. Proposed plant comprises transit gas duct with shut-off valve, processing zone communicated with the latter via opening in its bottom and made up of vertical trunk divided by vertical baffle plates into parallel gas ducts with inlet and outlet valves. Cleaning and recovery units are built in said parallel ducts, each being made up of absorbing air heater with three stages of smoke fumes cleaning. Oxidation chamber is arranged between first and second stages accommodating ozone-air mix feed branch pipe furnished with nozzle made up of cone with hemispherical perforated bottom. Averaging chamber is arranged between second and third cooling stages.
EFFECT: higher efficiency.
