ンテナンスを必要とする課題があった。The conventional device is constructed as described above, and a voltage is applied to the liquid in order to electrostatically agglomerate the impurity particles in the liquid. When the liquid is oil-based, for example, a high voltage of 450 V can be applied, so that the oil molecules and the impurity particles in the oil have the same potential, and the potential difference between them causes
The zeta potential generated at the interface between the oil molecules and the impurity particles in the oil is canceled, and electrostatic coagulation occurs immediately as shown by the characteristic curve iii in FIG. 10 if the liquid is water
When energizing at a current of mA or more, hydrogen gas is generated, so that only a low voltage of about 2 V can be applied, and there is a problem that electrostatic agglomeration does not occur as shown by the characteristic curve ii in FIG. Further, since the electrode cassette 24 is composed of the first and second mesh electrodes 25 and 26 made of stainless steel, it is expensive, the electrode cassette 24 cannot be discarded, and dirty maintenance for exchanging the adsorbent 7 is required. There was a task to do.

る。Next, this operation will be described with reference to FIG. FIG. 3 shows a potential characteristic curve in which the vertical axis represents the repulsive force P 1 and the attractive force P 2 , and the horizontal axis represents the interparticle distance L between the impurity particles A and B. When the impurity particles A and B are mixed in the liquid,
The potential of the liquid molecules themselves around the impurity particles A and B,
Due to the potential difference between the potentials of the impurity particles A and B themselves, a zeta potential is generated around the impurity particles A and B. Impurity particles other than metals - has a potential, - repelled by zeta potential of comrades, repulsive force P 1 at a distance L 1 is 0
And is stable. In this state, if some force is applied and the distance between the impurity particles A and B is reduced, the repulsive force P 1 increases as shown by the characteristic curve i in FIG.
When approaching 2 or less, attractive force P 2 acts to cause electrostatic aggregation.
When the liquid is oil, a high voltage DC450V is applied, so that both the oil molecules and the impurity particles A and B are DC450V,
The zeta potential is canceled and immediately causes electrostatic aggregation as shown by the characteristic curve iii in FIG. When the liquid is water-based, hydrogen gas is generated when the energization current value exceeds 10 mA, so that, for example, only a low voltage DC2V can be applied. With DC2V,
Since there is no great difference from the ground potential, electrostatic aggregation does not occur as shown by the characteristic curve ii in FIG. In order to generate electrostatic agglomeration under any condition, the distance L between the impurity particles A and B is set to a distance L 2 or less by the action of the adsorbent 7 so that no static voltage is applied. Electrocoagulation can occur.

Glass wool or cellulose is the main component, and the impurity particles A and B are entangled or aggregated to bring the distance between the impurity particles A and B close to a distance L 2 or less shown in FIG. It causes electrocoagulation. This is a special one that does not cause electrostatic cohesion at all with generally known adsorbents, activated carbon, activated clay and the like. For example, an adsorbent 7 whose main component is magnesium
Reacts magnesium sulfate with magnesium hydroxide in the presence of special phosphate to produce fibrous crystals by hydrothermal reaction. The components are, for example, basic magnesium sulfate: 80 to 100%, magnesium hydroxide: 0 to 20%, and magnesium sulfate: 0 to 5%. Further, the adsorbent 7 containing calcium as a main component produces fibrous crystals by hydrothermal reaction of slaked lime and silica, and the components thereof are, for example, silica: 20% to 80%,
Calcium oxide: 20% to 80%. Further, the adsorbent 7 containing cellulose as a main component is produced by acid-hydrolyzing the selected pulp, washing with filtered water, dehydration and drying, and then pulverizing, or separating the selected pulp into short fibers and then dehydrating and drying,

The liquid that flows into the container 11 from the electrode passes through the electrode 19 and the first filtration layer 3 and reaches the adsorbent 7. The adsorbent 7 causes the electrostatic particles to agglomerate by entanglement or agglomeration of the impurity particles to bring the mutual distance between the impurity particles closer to the distance L 2 or less shown in FIG. The impurities, which have been formed into hundreds of lumps due to the electrostatic aggregation, are accumulated on the outer periphery of the second filtration layer 4 having a sufficiently coarse mesh with respect to each impurity particle, and are cake-filtered. The liquid filtered in the second filtration layer 4 is
It flows out of the container 11 from the outflow port 13 via the pipe 16.

方が効果が得られる。In the embodiment shown in FIGS. 1 and 2, a voltage may be applied to the electrode 19 to assist the electrostatic aggregation action of the adsorbent 7. For example, cleaning solution: Neos Detergent 1
700%, 5% dilution, 3% machine oil (30,000
ppm) is mixed, an adsorbent containing magnesium as a main component is used, a filter is 10 μm, a DC voltage of +2 V is applied to the electrode 19, and a cleaning liquid is not applied. The effect of removing oil content is 30,000 ppm when a voltage is applied when the cleaning liquid is circulated 20 times in the apparatus of FIG.
To 810 ppm, and from 30,000 ppm to 1,400 ppm when no voltage is applied. Therefore, even if the voltage is 2 V, the effect is obtained when the voltage is applied.

The blind membrane 22 is provided, and even if the adsorbent 7 is worn out, the blind membrane 2
At 2, the liquid is prevented from flowing through the cavity of the adsorbent 7 and passing through the adsorbent 7 as it is. Furthermore, when the adsorbent 7 is mainly composed of a substance such as cellulose that is easily worn out, if a substance having a mass close to the mass such as cellulose, for example, a granular state or a powdered state such as cork or polypropylene, is mixed as a measure against the loss, the loss will be reduced. Is improved. The mixing volume ratio is preferably adsorbent: mixture = 0.5 to 5: 1. Furthermore, the blind plate 23 is provided to prevent the adsorbent 7 from being blown off by the flow rate of the liquid from the inflow port 12 and the second filter layer 4 having a coarse mesh being exposed. Although the blind plate 23 is provided on the electrode 19,
The portion of the electrode 19 facing the inflow port 12 may be formed in a blind shape, or the portion of the tubular body 1 facing the inflow port 12 may be formed in a blind shape.

にすることができる効果を有する。According to the invention of claim 1, the adsorbent is composed of a granular or powdery material containing at least one of magnesium, potassium, aluminum borate, glass wool and cellulose as a main component. The interatomic distance of the impurity particles in the liquid passing through is narrowed by entanglement or agglomeration of the impurity particles to a distance at which the mutual impurity particles can cause electrostatic coagulation, and the microparticles in the liquid are adsorbent. After passing through the inside, after causing electrostatic agglomeration, the impurity particles are filtered with a sufficiently coarse second filtration layer, and the adsorbent is stored in a resin container. Since it is made into a cassette, there is an effect that electrostatic coagulation can be surely caused by a simple device and maintenance can be facilitated.
