SANITARY CHIMNEY NOZZLE Russian patent published in 2021 - IPC B01D53/60 

FIELD: power engineering.

SUBSTANCE: invention relates to heat power engineering and can be used to clean the flue gases of furnaces burning biological materials from harmful impurities and odorants. The effect is achieved by the fact that the proposed sanitary nozzle for the chimney contains a body made of corrosion-resistant material in the form of a vertical cylindrical toroidal pipe, perforated from the inner and outer sides, closed from the upper and lower ends with the upper and lower end horizontal rings, provided with the bottom an inner vertical mounting ring, to which the guide vanes are attached along the inner perimeter, the outer perimeter of the lower end ring is equipped with an outer annular inclined visor, the cavity of the branch pipe is divided by vertical partitions connected to the upper and lower end horizontal rings, forming a slag and carbon vertical sections, and the upper horizontal ring is perforated in the areas covering the slag sections filled with granules, made of metallurgical slag, the coal section is closed from above with a continuous section of the end horizontal section and filled with granules of activated carbon, and the pipe itself is inserted with an installation ring inside the chimney mouth, and a deflector is put on the toroidal pipe, the diameter of the conical cover of which is equal to the inner diameter of the above pipe.

EFFECT: improvement of method for cleaning the flue gases of furnaces burning biological materials from harmful impurities and odorants.
