FIELD: processing and recycling of wastes; ecology.
SUBSTANCE: invention relates to purification of flue gases emitted in atmosphere by industrial vertical pipes. Proposed method includes assembling of horizontal pipe barrel to preset length of links, made of sheet steel, wherein outer surface of horizontal pipe barrel is coated with metal coating, filled with water for cooling of passing hot smoke flow. Wherein flue gas from emission source is directed to soot trap and then it is directed to initial part of horizontal pipe with help of smoke exhaust, where it is mixed with atmospheric air flow by means of artificial draft. Obtained smoke mixture is directed at rate of 8-14 m/s through conical part of horizontal pipe, length of which is equal to 1/4 of horizontal pipe length, diameter is 1/10 of horizontal pipe diameter, to surface purification plant for semifine purification by sprinkling neutralizing chemical solution and then for fine purification by means of filters of metal shavings and self-purifying filters, where smoke mixture is purified with coefficient of up to 98 %, avoiding hazardous gas emissions into atmosphere.
EFFECT: technical result is prevention of hazardous gas emissions into atmosphere.
