請されている。[Problems of the Prior Art to be Solved by the Invention] Conventionally, as a device for removing carbon particles in lubricating oil, there is a device called a roll tissue vapor filter, which is mainly a cotton linter valve wound into a roll. However, such a filter has a problem in that the removal rate of carbon particles is extremely low. On the other hand, for example,
In JP 8-137452, a filter body 8 is constructed in which a collection member made of a porous dielectric material is interposed between both positive and negative electrodes for the purpose of improving the collection rate! (electrostatic oil purifier) has been proposed. Although this device improves the collection rate, the device is large in size for diesel engines, so there is a need for a smaller oil purifying device with a higher collection rate.

対応する捕集部材の位置にシール部材を設けている。[Means for Solving Technical Problems] The present invention has been made in response to such a request, and includes disposing a spacer member through which contaminated oil flows on the negative potential side of the electrode and removing carbon particles from the contaminated oil. A collection member to be collected is arranged on the positive potential side of the electrode, and a seal member is provided at a position of the collection member corresponding to the outlet on the downstream side of the contaminated oil of the spacer member.

時間に効率良く汚染油中のカーボン捕集が可能となる。By providing a sealing member at a position within the collection member corresponding to the contaminated oil downstream outlet of the spacer member, separation of carbon deposits accumulated on the collection member due to the flow of contaminated oil is prevented,
Confinement within the collection member can be effectively performed, and carbon in contaminated oil can be efficiently collected in a short time.

の方法で設けられる。2 is a flat plate electrode made of aluminum foil, to which a negative potential is applied. Electrodes 1 and 2 and electrodes 1' and 2 each constitute a pair of electrodes. Reference numeral 3 denotes a porous spacer member made of an electrically insulating material, which is arranged on the electrode 2 side to which the negative potential of the DC high voltage source 7 is applied, and contaminated oil flows from upstream to downstream (from the bottom to the top in the drawing). Reference numeral 4 denotes a collection member made of a porous material, which is disposed on the side of the electrodes 1 and 1' to which a positive potential is applied, and collects carbon particles from contaminated oil flowing through the spacer member 3. 5 is a porous dielectric film having micropores;
It is formed between the spacer member 3 and the collection member 4, and allows carbon particles in the contaminated oil to permeate from the spacer member 3 to the collection member 4. , 6 is a sealing member made of silicone rubber or the like, and is provided by adhesive or the like on the entire downstream outlet end of the spacer member 3 at a position within the collecting member 4 corresponding to the vicinity of the contaminated oil downstream outlet.

A porous body is used.

心円筒部上端方向から流入され、ろ過体下端部の複数の
開口から噴出される。The electrostatic oil purification filtration unit F shown in FIG. 1 and having the above configuration is configured into an electrostatic oil purification filter body by stacking the oil purification filters in an a-layer winding shape as shown in FIG. 2. Contaminated oil flows in from the upper end of the central cylindrical portion of the roll-shaped filter and is ejected from a plurality of openings at the lower end of the filter.
この汚染油はろ過ユニットＦのＦＭ側（上流側）から流
入し、上端側（下流側）出口から浄油として流出する。This contaminated oil flows into the filtration unit F from the FM side (upstream side) and flows out from the upper end side (downstream side) outlet as purified oil.
汚染油中のカーボン粒子は正常分散剤と結合し。The carbon particles in the contaminated oil are normally combined with the dispersant.
てミセル構造を形成し負に帯電しているため、カーボン
粒子は正の電極１の方向に引き寄せられる。Since the carbon particles form a micelle structure and are negatively charged, the carbon particles are attracted toward the positive electrode 1.

子は凝集しつつ捕集部材４の骨格上に堆積していく。However, when they come into contact with the polarized dielectric film 5, the micelle structure is destroyed, the charge on the carbon particles disappears, and the carbon particles begin to aggregate. The average particle size of the carbon particles grows from 0.4 μm to about 1.5 μm. after that,
The carbon particles that have passed through the II body membrane 5 due to Brownian motion or the like are deposited on the skeleton of the collection member 4 while being aggregated.

問題にならない。The oil downstream side of the collection member 4 is sealed with a seal member 6. However, the negatively charged carbon particles are attracted to the positive electrode side and collect on the collection member 4, but the purified oil with the carbon particles removed and the viscosity lowered flows through the spacer member 3 side, so it is sealed. Distribution resistance due to this is not a particular problem.

た。The collection performance when the seal member 6 was provided was 40% more collected than when the seal member was not provided. or,
When a seal member was provided on the upstream side of the oil, the amount collected was 10% less than when no seal member was provided here. From this result, it was found that providing the seal member downstream of the collection member is effective in trapping carbon particles.
