METHOD OF AND PLANT FOR COMPLEX CLEANING OF DIESEL FUEL Russian patent published in 2005 - IPC

FIELD: mechanical engineering; diesel engines.

SUBSTANCE: invention can be used for preparing for combustion diesel fuels with improved ecological and operating characteristics. Proposed method of complex cleaning of diesel fuel includes heating of diesel fuel, homogenization and separation in field of centrifugal forces with saturation of air with oxygen in process of circulation in closed circuit including intake space, heat exchanger and open-type rotary disk swirler, and subsequent fine filtering. In process of circulation of diesel fuel along closed circuit, fuel is exposed to action of ultraviolet radiation at v=380-460 nm, and then separation and fine filtering are carried out. Proposed plant for complex cleaning of diesel fuel contains open-type rotation disk swirler with inlet, outlet and drain branch pipes placed in circulation circuit together with intake reservoir, pressure pump and heat exchanger, transfer pump whose input is connected to outlet branch pipe of open-type rotary disk swirler, and output is connected with fine cleaning filter, supply and outlet pipelines connected, respectively, to intake reservoir and fine filter. Ultraviolet radiation unit is connected additionally to circulation circuit between outlet branch pipe of open-type rotary disk swirler and intake reservoir. Heater with bypass main line is connected between heat exchanger and inlet branch pipe of open-type rotary disk swirler.

EFFECT: improved efficiency of removal of polycyclic hydrocarbons including gummy-asphaltene compositions, from diesel fuel in process of its treatment using open-type rotary disk swirler.
