FILTER FOR PURIFICATION OF LIQUID MEDIUMS Russian patent published in 2004 - IPC

FIELD: filters for purification of liquid mediums.

SUBSTANCE: the invention is dealt with devices for purification of liquid mediums (solutions, suspensions, dispersions, etc.) from dissolved organic substances and mechanical impurities also may be used in different industries, in particular, for purification of working mixtures of absorbents, potable water, alcohol, sewage, dissolvents, etc. The filter contains a vertical cylindrical body with an inlet branch-pipe, branch-pipes and a filtering member installed with a ring-type clearance with regard to the body. In the ring-type clearance there is accumulative-distributive section with one or two channels for distribution of a liquid. At that the section is linked to the inlet branch-pipe and the channel or channels - with a cavity of the body. The accumulative-distributive section and the channel or channels for distribution of a liquid are formed by an inner surface of the body and an installed in the body vertical guide of a curvilinear profile, bounded above and from below by plates. At that the channel or channels have a profile of the diffuser type in a cross-section. In the ring-type clearance between the body and the filtering member there are guiding plates equal in height to the filter member and mounted tangentially to its surface with a positive allowance with respect to each other. At that the total flow cross-section of the positive allowances does not exceed three flow cross-sections of the inlet branch-pipe. The guiding plates are made with the bent inside edges. The technical effect is an increase of efficiency of purification of liquid mediums from dissolved organic matters and mechanical impurities and elongation of service life of the filter.

EFFECT: the invention ensures increased efficiency of purification of liquid mediums from dissolved organic matters and mechanical impurities and elongation of service life of the filter.
