SANITARY ATTACHMENT FOR AUTONOMOUS HEAT GENERATORS OF HEAT SUPPLY SYSTEMS Russian patent published in 2019 - IPC E04H12/28 F23J15/02 B01D53/46 

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat engineering and can be used for cleaning of flue gases of heat generators of roof boiler rooms and apartment heating systems from harmful impurities. Sanitary attachment for heat generators of autonomous heat supply systems comprises a box made of corrosion-resistant material, laid on the upper floor of the building, connected on the side edges to the atmosphere through stacks of height H, equipped with deflectors, wherein inside box at variable height H₁ from its bottom are laid on support plates and vertical partitions perforated baskets filled with pumice granules made of metallurgical slag with basicity module M > 1 and diameter of granules from 5 to 10 mm, above baskets at height H₂ under box cover there are flushing, perforated from below pipes, connected from outside box with collector of water supply, front edge of box is connected to gas-sewer header, bottom of the box is sloped I, equal to angle of natural slope of water, directed towards gas-sewer collector, which bottom is equipped with holes connected to channels of individual chimneys and sewer stands, in which upper edges of pipes of individual chimneys are located above level of surface of its bottom by value δ, and upper edges of sewer stands are located at level of surface of its bottom.

EFFECT: technical result is higher reliability and efficiency of sanitary attachment.
