APPARATUS FOR CLEANING DIESEL FUEL Russian patent published in 2014 - IPC C10G31/09 B01D36/04 

FIELD: chemistry.

SUBSTANCE: invention relates to an apparatus having a housing 1 with a pipe for discharging a portion of diesel fuel to be cleaned 10 in a perforated bottom 9, a cover 2 with an inlet pipe 3, a hydrodynamic filter element mounted by a spring 4, having a porous partition wall 6 made in form of a truncated regular hexagonal pyramid from hydrophobic resin-separating material and placed between flat bases, the top 5 one of which is connected to the inlet pipe 3 and the bottom 7 one is connected to the pipe for discharging a portion of the diesel fuel to be cleaned 10. A cylindrical nozzle 12 is mounted on the outer side of the bottom 9, said nozzle being equipped with an outlet pipe for cleaned diesel fuel 19 and a pipe for draining sludge 17, in which there is an additional hydrodynamic filter element, having a porous partition wall 14, made in form of a truncated regular hexagonal pyramid from hydrophobic resin-separating material, top and bottom flat bases 13 and 15, connected to the pipe for discharging a portion of the diesel fuel to be cleaned 10 and the pipe for draining sludge 17, respectively. The ratio of the total area of the side faces of the porous partition wall 14 of the additional filter element to the total area of the side faces of the porous partition wall 6 of the filter element placed in the housing 1 is equal to 1:10.

EFFECT: high efficiency of cleaning diesel fuel by filtering by avoiding removal of a portion of diesel fuel in order to remove oxidation products.
