FIELD: technological processes. ^ SUBSTANCE: invention may be used in garbage incineration plants in various industries. Gaseous wastes produced in combustion chamber 1, 3 and cooled in jacket 5 are supplied into dust arrester 7, and then in the first scrubber 8. In scrubber 8 via pipeline 19 water is supplied, and hydrochloric acid is discharged via pipeline 16. Partially cleaned gases are sent into the second scrubber 9, where selective cleaning of sulfur dioxide SO2 is carried out with the help of supplied ammonia solution 12. Produced aqueous solution of ammonium sulfate/sulfite is fully or partially returned to combustion chamber. ^ EFFECT: simultaneous reduction of carbon monoxide, halogenated organic compounds and nitrogen oxides NOx. ^ 4 cl, 5 dwg, 1 ex |
