ENVIRONMENTALLY FRIENDLY NOZZLE FOR CHIMNEY Russian patent published in 2020 - IPC B01D53/60 

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat engineering and can be used for cleaning of flue gases of heat generators of autonomous and apartment heat supply against harmful impurities. Proposed eco-friendly nozzle for chimney comprises housing made of corrosion-resistant material, in form of vertical cylindrical toroidal perforated from all sides of branch pipe, which cavity is filled with pumice granules, made from metallurgical slag with basicity module M>1 and granules diameter from 5 to 10 mm, equipped from below with inner vertical mounting ring 3, to which along inner perimeter guide blades are attached, on toroidal branch pipe there is a deflector, which conical cover diameter is equal to inner diameter of the above branch pipe, and the branch pipe itself is inserted by the mounting ring into the mouth of the chimney, which is equipped with an external circular inclined shield, wherein angles of inclination of the conical cover of the deflector and the inclined shield are equal to the angle of the natural slope of water.

EFFECT: higher efficiency of environmentally friendly nozzle for chimney.
