Abstract

PURPOSE:To obtain an electrostatic purifier which is small-sized and less in dangerous properties by providing the electrodes having mutually different polarities to the inside of a vessel in which liquid is flowed and making the distance between the electrodes constant and below. CONSTITUTION:The electrodes 15, 16 having mutually different polarities are provided to the inside of a vessel 2 in which liquid is flowed and the distance between the electrodes 15, 16 are regulated to <=6mm. DC voltage is impressed between the electrodes 15, 16 to collect the fine granular substances and to remove them. By this method, the whole apparatus can be made small-sized and also even if high voltage is not used, the trapping capacity is large and the energy consumption is less and the dangerous properties are decreased.

比べればその差は明瞭である。According to the membrane specimen in Figure 4, as the distance between the electrodes is shortened from Experimental Example 1 to Experimental Example 6, the voltage decreases from 1000V to 100V in proportion to the distance between the electrodes, and the electric field It is observed that the color tone has become lighter even though the experiment was conducted under conditions of strength. When comparing Experimental Example 1 and Experimental Example 6, the difference is clear.

すなわち、静電浄化装置により不純微粒子を捕獲する度
合いは、単に電場強さに影響されるばかりでなく、電極
間距離が極めて大きな影響を及ぼしていることが判る。In other words, it can be seen that the degree to which impure particles are captured by the electrostatic purification device is not only affected by the electric field strength, but also greatly influenced by the distance between the electrodes.

第５図の写真により比較すると実験例３の方が参考例２
よりも同等もしくはそれ以上に色調が薄くなっている。Comparing the photos in Figure 5, Experimental Example 3 is better than Reference Example 2.
The color tone is the same or even lighter than that of .

つまり、電極間距離を６ａｍ以下であれば市販の濾過式
オイルフィルターよりも捕集効果が高い静電浄化装置と
なる。In other words, if the distance between the electrodes is 6 am or less, the electrostatic purification device will have a higher collection effect than commercially available oil filters.

また、電圧について検討すると、実験例３から実験例６

In the range of , the applied voltage is 600 V or less, and if the distance between the electrodes is 6 am or less, electrostatic purification can be performed using a low voltage without using the high voltage specified in the electrical equipment technical standards.

なお、第６図および第７図の写真から分るように、電極
間距離１を１〜４麿にすれば一層効果がある。In addition, as can be seen from the photographs in FIGS. 6 and 7, it is more effective if the distance 1 between the electrodes is set to 1 to 4 mm.

It gets expensive. Furthermore, the container of the electrostatic purifier can be made much smaller than the conventional electrostatic purifier which has a distance between electrodes of 50 cm. For example, even assuming an automobile engine room, by reducing the distance between the electrodes to 6 layers or less, the filter will be about the same size as a normal full-flow type filter, and will fit in the automobile engine room.

。Further, FIG. 10 shows still another embodiment of the present invention. In this embodiment, a strainer 30 is located above the 7 flange portion 3a of the lower container 3 and in front of the oil flow of the electrode assembly 1.
This prevents coarse particles from entering the electrode assembly 1 and prevents short circuits between the electrodes due to coarse particles. Note that such a strainer 30 may be attached to the inflow lower.

Because it demonstrates the ability to capture more than
Power consumption can be reduced and danger can be reduced.

Scope of Claims (1) Electrodes with different polarities are provided in a container through which a liquid flows, and a direct current voltage is applied between these electrodes to generate an electric field in the liquid. In a purification device that collects and removes carbon dioxide on electrodes, the distance between the electrodes is set to 6.
A liquid electrostatic purification device characterized in that the electrostatic purification device is set to less than m. (2) The liquid electrostatic purification device according to claim aE1, wherein the liquid is engine oil. (3) A device for electrostatic purification of liquid according to claim 1 or 2, characterized in that an insulating filter is provided between the electrodes, which serves both to collect particulate matter and to insulate between the electrodes. . (4) The electrostatic charge of liquid according to claim 1, 2 or 3, characterized in that a strainer for capturing coarse substances is provided on the liquid inflow side of the container rather than the electrode.
