FILTER FOR BIODIESEL FUEL Russian patent published in 2017 - IPC F02M37/22 F23K5/18 B01D29/56 

FIELD: power industry.

SUBSTANCE: filter for biodiesel fuel contains a housing 1 with inlet 2 and outlet 3 channels, the inlet cavity 4, formed by coaxially located outer 5 and inner 6 walls, in which a blade hydrocyclone swirler 7, a sediment bowl 8 with drain cock 9 and sludge level sensor 10, filter element 11 and a flows spreader 12 is located . The blade hydrocyclone swirler 7 is located at the outlet 13 from the inlet cavity 4 and made as a ring, on which the blades 14 are formed along the outer edge with the inclination from the axis line from 8° to 12° to the cross-section plane 15, and the total average blade length projection 14 is larger than the average length of the inlet cavity circle 4 at 8-12% for each of the radial distances from the filter axis. The flows separator 12 is designed as a plate part 16 with a truncated cone 17 and radial ribs 18, the larger base 19 of which is directed to the filter element 11, and the ribs 18 are arranged along the plane 20 of the longitudinal section from the sediment bowl 8, and a sediment bowl 8 is made of two coupled between each other parts, the upper cylinder 21 and the lower conical 22, and the upper point 23 of the sludge level sensor 10 is located in the interface plane 24 of the cylindrical 21 and conical 22 parts of the sediment bowl 8.

EFFECT: invention improves the reliability and efficiency of the biodiesel fuel filter.
