分離した後の液体に気泡が再混入することが防げる。By applying the multi-phase AC electrodes of three or more phases, the liquid in the container is moved by the electrohydrodynamic effect due to the unequal traveling wave electric field generated in the container, and the bubbles in the liquid also form a mesh. It is moved towards the electrodes. The bubbles carried to the mesh electrode are pushed to the center of the mesh electrode where the electric field is weak. At this time, the mesh electrode is
Since the gradient of the electric field is large, the force acting on the bubbles is large,
Therefore, the bubbles are easily collected in the central portion of the mesh electrode. The collected bubbles are pushed out to the external space by a force proportional to the lines of electric force generated in the external space, and are discharged by coming into contact with the gas in the external space. If the circulation line is provided, the liquid moved to the mesh-shaped electrode together with the bubbles can be returned to the bottom of the container, so that the bubbles can be prevented from being remixed in the liquid after the bubbles are separated.

By applying a voltage to each of the electric wires 11a, 11b, and 11c, an unequal traveling wave electric field is generated in the inner peripheral portion and the outer peripheral portion of the electrohydrodynamic pump element 12, and the electrohydrodynamic effect due to the unequal traveling wave electric field is generated. A force for moving the liquid 2 contained in the container 1 from the lower part to the upper part of the container 1 is applied.

Due to the electrohydrodynamic effect of the electric field, it is carried toward the mesh-shaped electrode 8 at the upper position, and at the same time, it is moved toward the center as it goes upward.

The bubble 3 in the inside receives the interaction force between the polarized electric charge of the bubble and the electric field due to the electric field along the tangent line of the electric force line 10 generated between the electric wires 4 and 5 of the mesh-shaped electrode 8.
According to the equation (1), the electric field is collected in the weak direction, that is, in the central portion of the mesh electrode 8 (position A in FIG. 2). or,
As shown in FIG. 1B, the electric wires 4, 5 of the mesh electrode 8
Since the lines of electric force 10 generated between them also exist in the external space 15, the bubbles 3 collected in the central portion of the mesh electrode 8 are formed.
Are extruded into the external space 15. 16 is a liquid surface.
At this time, since the mesh-shaped electrode 8 is woven by the electric wire 4 corresponding to the warp thread and the electric wire 5 corresponding to the weft thread, the gradient of the electric field is large (that is, gradE 2 in the above formula (1) is large). Since the force acting on the bubbles 3 is large, the action of separating and collecting the bubbles can be surely performed.

There is no risk that the separated bubbles 3 will be mixed again in the liquid.
At this time, if the position above the circulation pipe 14 is near the wall of the container 1 having few bubbles 3, the effect can be further enhanced.

Although the AC power source 9 is used as the power source of the above, the wires 4 and 5 may be connected to the DC power source 15 as shown in FIG. 4, and the mesh size of the mesh electrode 8 is arbitrary. In addition, it is possible to easily remove bubbles having a large diameter, and the electrohydrodynamic pump element 12 for liquid transfer has a three-phase AC electrode.
Although the multi-phase AC electrode having more than one phase may be used, and the mesh-shaped electrode 8 has a structure in which the electric wires 4 and 5 are woven in a plain weave shape, the electric wires 4 and 5 arranged in parallel are simply superposed in a right angle direction.

Further, the electrohydrodynamic pump element is formed by densely winding it in a spiral shape, and liquid and bubbles moved by an unequal electric field generated in the electrohydrodynamic pump element are separated and collected in a weak electric field direction. Since the mesh electrode is arranged on the upper part of the container, when the liquid in the container and the bubbles in the liquid are carried to the mesh electrode by the electrohydrodynamic effect, the electric field of the mesh electrode is bubbled to the central part where the electric field is weak. The air bubbles are collected, and the collected air bubbles are separated and discharged by contacting the outside gas. Therefore, it is possible to easily remove the air bubbles without passing through the gas permeable membrane due to the pressure difference as in the conventional method, and the mesh Since the electrode has a large electric field gradient, the force acting on the bubbles is large, the discharge effect is large, and the electrostatic field causes no power consumption, and the circulation pipe is installed in the container to move the electrode. By circulating the generated liquid, there is no risk that the separated bubbles will be re-mixed in the liquid, and the mesh-shaped electrode can remove bubbles with a large diameter in the container by changing the mesh openings. There is also an effect that it can be achieved.
