Abstract
Abstract An apparatus for reforming fuel oil wherein ultrasonic waves are utilized. The apparatus comprises a closed vessel (15), a rotary collector (25) formed in a cylindrical shape, an inlet conduit (22) for supplying fuel oil to be reformed into the vessel, an outlet conduit (33) for delivering reformed oil from the vessel, and a ultrasonic irradiating device (3). The rotary collector has a layered mesh structure (23) of a fine mesh, preferably of mesh size between 2 pm and 20 µm, mounted thereon so that sludge contained in the fuel oil to be reformed (21) is collected on the layered mesh structure (23). One end of a horn (4) connected to the ultrasonic wave irradiating device (3) faces the layered mesh structure (23) forming a small gap therebetween so that the sludge collected on the layered mesh structure is dispersed by the ultrasonic waves.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
183 words
An apparatus for reforming fuel oil wherein ultrasonic waves are utilized and which comprises: a closed vessel means; a rotary collector means, having a layered mesh structure mounted thereon for continuously collecting sludge contained in said fuel oil and encircling an axis, which means is disposed within said vessel means so that said vessel means is partitioned into inlet and outlet chambers; an inlet conduit, connected to said inlet chamber, for supplying fuel oil to be reformed to said· vessel means; an outlet conduit, connected to said outlet chamber, for delivering reformed fuel oil; and a means for generating ultrasonic waves provided with a device for irradiating said ultrasonic waves into said vessel means, which apparatus is characterized in that: said rotary collector means is supported rotatably about said axis; and the end of said ultrasonic wave irradiating device is positioned adjacent to said rotary collector means forming a small gap therebetween, whereby said sludge collected on said rotary mesh structure is reformed by means of said ultrasonic waves being irradiated from said device as said rotary collector means rotates about said axis.
