Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bubble generator used for water purification and the like, and more particularly to an ultrafine bubble generator capable of generating ultrafine bubbles.
[0002]
[Prior art]
Since fine bubbles can adsorb organic substances contained in water to the surface of the bubbles and float on the water surface, it is said that they are effective for water purification and aquatic organism growth. No.-325042 discloses a water purification apparatus for fish farming that purifies the water for fish farming by generating bubbles using a diffuser module made of porous pumice or the like. .
[0003]
[Problems to be solved by the invention]
However, in the case of a purification device that adsorbs and disperses water-borne pollutants by bubbles generated from the air diffusion module, it can be purified to a certain level, but extremely fine (ultrafine) contaminant particles. It was difficult to adsorb and collect the pollutant, and the contaminants could not be completely removed.
[0004]
In order to adsorb and collect fine pollutant particles (pollutant substances), it is necessary to generate a large number of fine bubbles comparable to that to have a large contact area with the treated water. Porous materials such as pumice have a limit on the size of bubbles, and in the case of fine holes, there is a problem that bubbles cannot be generated due to the clogging of contaminants.
[0005]
Also, if you send strong air to eliminate the clogging of the pollutants, you will need to increase the capacity of the pump and the pressure resistance of the piping. There was a problem.
[0006]
Therefore, the technical problem of the present invention is to provide an ultrafine bubble generating apparatus capable of continuously generating ultrafine bubbles using an apparatus having a relatively simple structure.
[0007]

It becomes ultrafine bubbles and gradually rises in the water to be treated. By continuously circulating the water to be treated and heating and boiling, it is possible to continuously generate ultrafine bubbles. enable.
[0012]
According to the measures according to claim 2 as described above (2), making the passage of a conductive pipe, such as a metal pipe, or heated by applying a current to the pipe, or by heating at a high frequency, some If heating is performed using a heat generating element and water is heated to boiling and sent to the water to be treated, ultrafine bubbles can be generated.
Therefore, it is possible to further promote the supply of oxygen to the water to be treated.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of an ultrafine bubble generating device according to the present invention will be described with reference to the drawings. FIG. 1 shows a configuration of an ultrafine bubble generating device according to the present invention configured in a throw-in manner. The throw-in type bubble generator 5 includes a filter 6, a pump chamber 8 connected to the filter 6 via a communication pipe 7, a flow path 8 ′ projecting from the pump chamber 8, and a flow path 8 ′. The heating device 9 (boiling means) and the power supply line 10 are provided.
[0015]
When the bubble generating device 5 configured as described above is thrown (submitted) into the processing target water 1W placed in the water tank and the operation is started, a micropump (not shown) provided in the pump chamber 8 is processed. 1 W is filtered and taken in by the filter 6, heated and boiled by the heating device 9, converted into water vapor from the head of the flow path 8 ′ and discharged (reduced) into the water 1 W to be treated, so that ultrafine bubbles are treated with water to be treated As long as it can be generated at 1 W and the operation of the pump and the heating of the heating device 9 are continued, ultrafine bubbles can be generated continuously.
[0016]
FIG. 2 is an exploded perspective view showing a specific configuration example of the above-described flow path 8 ′, in which 11 is a cover plate provided with an injection port 11T, 12 is a substrate made of glass or ceramic, 13 Is a water conduit, 14 is a conductor, 15 is a heat generating element, and the heat generating element 15 is formed by fixing the cover plate 11 on the substrate 12 so that the convex portion 11A provided on the bottom surface thereof coincides with the concave portion 12B. A water conduit 13 having a conductor 14 that generates heat is configured, and the supply water 2W or circulating water sent from the direction of the arrow shown in the figure can be heated and boiled and then discharged from the injection port 11T.
[0017]
Since the ultrafine bubble generating device according to the present invention has the above-described configuration, as shown in FIG. 1 , the throwing-type bubble generating device 5 is thrown into the water to be treated 1W placed in the water tank , and then the pump and By turning on the heating device 9 and discharging the heated and boiled water from the flow path 8 ', ultrafine bubbles can be generated in the water 1W to be treated.
[0018]
In addition, as a method of moving water in each channel 8 ', there are a method using a pump, a method based on the generation of negative pressure in the channel 8' after the generated bubbles are discharged to the water 1W to be treated, and the like. However, the selection is arbitrary.
[0019]
【The invention's effect】
As described above, according to the ultrafine bubble generator according to the present invention, a large amount of ultrafine bubbles are continuously generated in the water to be treated using an apparatus having a relatively simple structure. Therefore, fine pollutants (organic substances) present in the water to be treated can be adsorbed on the surface of the bubbles and floated on the surface of the water. It can demonstrate excellent effects for raising children.
