DEVICE FOR CLARIFICATION OF A LIQUID Russian patent published in 2004 - IPC

FIELD: devices for purification of natural and waste water from suspended particles and floating impurities. SUBSTANCE: the invention is dealt with devices for purification of natural and waste water from suspended particles and floating impurities and may be used in many industries. The device contains a housing, chambers of flocculation, sedimentation, the thin-layer components, the systems of delivery of an initial liquid, removal of a clarified liquid, a settling, non-floating impurities. Inside the chamber of flocculation there is a circulation chamber, in the lateral walls of which there are windows adjustable in cross-section, and in the bottom there is an automatic discharge valve. The lower parts of chambers of flocculation and settling are fused by a ring channel and in them the radial vanes and ring straightening lobes are installed. The technical result is a decrease of loading on the thin layer components that allows to reduce their area and dimensions of the device. The uniform distribution of a liquid stream along the whole cross-section area of the chamber of clarification ensures stabilization of a design mode of sedimentation in the thin layer components, excludes an outlet of the suspended particles through them and creates in the upper part of the chamber of sedimentation an effect of filtration in the suspended layer. EFFECT: the invention allows to decrease loading on the thin layer components, to reduce their area and dimensions of the device. 3 cl, 3 dwg
