MAGNETIC FILTER Russian patent published in 2017 - IPC B01D35/06 B03C1/28 

FIELD: chemistry.

SUBSTANCE: invention relates to magnetic cleaning of process liquids and can be especially efficiently used for separation of amine, used for cleaning of natural gas with high content of hydrogen sulphide. Magnetic filter comprises a reservoir, in cover of which there are cylindrical magnetic rods with sludge collecting rings worn thereon, movable plate for displacement of latter along rods, sludge-collecting rings are split and made of hardened alloy, having spring, non-magnetic and anticorrosion properties, for example, precision alloy 36NKHTYU, cladding of rods is made of stainless steel with solid chrome-plating, filter is equipped with a mechanism for post-treatment of sludge and its removal beyond filter, mechanism is made in form of installed in lower part of reservoir on a fixed axis of two pairs of pipes, welded into sleeve, which can rotate on fixed axis, tubes are provided with holes, into which is fed a cleaning medium under pressure, resultant reactive forces of flowing jets generate torque which rotates sleeve with tubes.

EFFECT: invention provides high degree of cleaning filter from slug.
