AERATOR Russian patent published in 2013 - IPC C02F3/18 

FIELD: chemistry.

SUBSTANCE: invention relates to aerator and can be applied in biological purification of sewage. Device includes dispersing element in form of porous pipe, which surrounds bearing pipe with clearance. Each end of porous pipe of dispersing element is hermetically surrounded by demountable ring-shaped cuff, which has possibility of holding porous pipe coaxially to bearing pipe. Ring-shaped cuff is made from flexible polymeric material or flexible-elastic material. Bearing pipe has possibility of reciprocal travel along ring-shaped cuffs, and ends of porous pipe have possibility of reciprocal travel between ring-shaped cuffs. Each ring-shaped cuff has possibility of hermetic surrounding of screw nut on bearing pipe.

EFFECT: increase of reliability of compressed air dispersion.
