Description

{GREEN ALGAE ELIMINATE APPARATUS}

Generally, green algae refers to algae having green color due to a large amount of chlorophyll (chlorophyll) as shown in Fig. 1 attached hereto.

These green algae consist of about 6,000 species. Green algae have central vacuoles, and pigments are contained in the pigment. Photosynthetic starch is formed and stored in a protein body called pyrenoid in the pigment. There are many kinds of sexual reproduction, and the spouse has two or four whip-like flagella. Asexual reproduction is made by cell division, mobility and non-homogeneous spores, or by segmentation. Most of them grow in fresh water, usually in rocks that are submerged in water, or they grow on garbage in water that is attached to the trees, or live on the ground or in the sea. Freely floating tiny algae are also sources of nutrients and oxygen to the creatures living in the water. It is important as a material to study the evolution of plants.

However, in eutrophicated lakes and slow-flowing streams, floating birds, that is, phytoplankton, are proliferating and accumulating on the surface of water, resulting in significantly changing the color of the water. These green algae occur only in freshwater, and are caused by the inflow of various land pollutants such as industrial wastewater, domestic sewage, fertilizer, pesticides, livestock and human manure into rivers or lakes, decomposed by bacteria, decomposed organisms Nitrogen and phosphorus, which feed on plankton, are generated and green tides occur in seawater and fresh water.

When such green algae are deepened, they decrease the dissolved oxygen in the water. They produce toxic green algae and various kinds of algae plankton to kill fishes and aquatic organisms. Also, in the bottom part of the sediments, It causes a lot of problems such as pollution of fresh water, poisoning of fish, and damage of environment and natural beauty. Therefore, conventionally, as shown in FIG. 2 of the accompanying drawings, it was only the operator to take off the harmful algae floating on the ship and to supply and distribute the loess.

To solve these problems, until now, many techniques for removing harmful algae have been introduced.

In addition, since the nano bubbles emitted from the nano bubble generator 100 installed in the harmful-bird-removing device 10 act near the water surface, the nano-bubbles directly act on the harmful birds, To remove harmful algae or inhibit proliferation.

In the present invention as described above, the nano bubble generator 100 outputs ultrasound waves at a nano bubble generation level that varies according to the water quality detected by the water quality detector 200 to decompose and remove harmful birds, To minimize the power consumption due to the continuous output of the nano bubbles.

In the present invention as described above, when the communication unit 300 sends the operation state of each unit to the control unit 20 or the communication unit 16 receives the signal transmitted from the control unit 20, And performs the control operations and displays the operation state visually or audibly through the input / output unit 17. [

Hereinafter, the nano bubble generation will be described in more detail.

First, when the main power switch of the input / output unit 400 is turned on, electric power is supplied to the electrical components of the apparatus. As a result, as shown in FIG. 9, The motors of the first and second bubble generating units 110 and 120 are rotated and the impellers 1 and 2 and 112 and 122 of the first and second bubble generating units 110 and 120 are rotated, Power is applied and the outside air is sucked.

The outside air forcedly sucked by the suction means F flows into the impeller 1 112 side of the first bubble generator 110 through the gas discharge pipe 1 152 and flows into the gas discharge pipe 2 (122) of the second bubble generator (120) through the first bubble generator (153).

At this time, the gas discharge pipe 1 (152) passes through a through hole (one end side of the outer tube of the housing 121 is bent and extends so as not to contact with the rotation axis L) Since the impeller 1 112 is located close to the front of the nut portion fixed to the rotation axis L, in a process of being discharged while being accelerated in a narrow gap between the tip portion of the gas discharge pipe 1 152 and the nut in the process of discharging the gas It produces pressure and velocity changes and at the same time cleaves or explodes and mixes with the fluid to create a fine bubble.

The gas discharge pipe 2 153 is provided with a gas inlet 142b (for example, a fixing nipple) fixed to the through hole of the carbody 142 constituting the tip end closing part 140 and a through hole (Not shown in the drawings) of the gas discharge pipe 2 (153) in the process of discharging the gas through the through hole (141a, 141a, the through hole not in contact with the rotation axis L) and located close to the tip end portion of the shaft fixing projection 122b of the impeller 2 It accelerates in a narrow gap between the tip end and the shaft fixing protrusion 122b, and causes a pressure and a velocity change in the process of discharging, and at the same time, splits or explodes and mixes with the fluid to generate a fine bubble.

As the water and air move as described above, the water collides with the fine particles while colliding with the water. In this crushing process, a pressure drop (negative pressure) is generated, and air collides with the inflow of the air, So that a nano bubble having a maximized dissolution rate is produced.

The fine bubbles are micro bubbles having a size of 1/100 to 1/1000 mm, that is, bubbles of 50 μm or less.

At the same time, since the impeller 1 112 of the first bubble generator 110 rotates, the fluid, that is, the water of the lake, is sucked into the fluid inflow hole 121a of the housing 121 and flows between the outer cylinder and the inner cylinder Through which the outer cylinder body is folded and extended so as not to contact with the rotation axis L, is accelerated and mixed with the gas in the process of passing through the narrow aperture.

At the same time, the impeller 2 122 of the second bubble generator 120 rotates, so that fluid, that is, water in the lake is sucked into the fluid inlet hole 142a of the drum 142, Through the narrow through hole 141a while being accelerated and mixed with the gas.

As described above, the fine bubbles generated in the first bubble generator 110 are mixed with the fluid by the thrust of the impeller 1 112, and the fine bubbles generated in the first bubble generator 110, Bubbles are generated while being split or exploded while being repeatedly caused by a change in pressure and speed, and are discharged to the vicinity of the main body of the nano bubble generator 100.

As described above, in the process of mixing the fine bubbles generated by the second bubble generator 120 with the fluid by the thrust of the impeller 2 122, the fine bubbles are discharged from the discharge tube 123 Bubbles are generated while being repeatedly subjected to pressure and speed changes while being cleaved or exploded, and are strongly discharged to the rear of the nano bubble generator 100.

The nano bubbles are ultrafine bubbles which can not be confirmed by eyes of 5 占 퐉 (micrometers, or microns, 1 占 퐉 = 0.001 mm) or less. Such nano bubbles increase the amount of dissolved oxygen, and pollutants including harmful algae It inhibits the proliferation of anaerobic bacteria and simultaneously destroys them. It activates and simultaneously increases aerobic bacteria to improve water quality, while the negative ions of nano bubbles combine with contaminants that are in a positive ion state, removing pollutants and heavy metals Or to neutralize them.

The nano bubbles can adsorb pollutants adhered to soil with a small particle diameter to separate contaminants from the soil and can more easily remove pollutants by chemical treatment. At this time, contaminants can be removed by neutralizing or oxidizing organic substances including heavy metals according to the nature of the nano bubble itself as described above.

In addition, in the first and second bubble generators 110 and 120 of the nano bubble generator 100 of the present invention, the air and water introduced due to the rotation of the ampere and the pressure of the discharge path, By forming a vortex in the water containing air, a large specific gravity is pushed outwardly by the centrifugal force and the air with a small specific gravity is pushed to the inner side to move. As the water and the air move in this way, water collides with the fine particles while colliding with the water. In this crushing process, a pressure drop (negative pressure) region is generated, and air collides with the inflow of such air, Thereby maximizing the dissolution rate.

The nano bubble generator 100 may further include a coil for electrically applying power to the interior of the first and second bubble generators 110 and 120 of the nano bubble generator 100 As the power is applied, the water passing through the nano bubble generator 100 is allowed to pass through the magnetic field to have an activity.

By adding the activity to the nano-bubble having the employment rate as described above, it is possible to double the efficiency of removing heavy metals and organic matters including toxic algae. In the above description, the term "having activity" means that hydroxyl ion (OH-) is generated in water to have anionic surface-active property, thereby facilitating sterilization and binding with harmful metal ions due to an electric field effect with a surfactant, The purification efficiency is improved.

Hereinafter, the effect of the nano-bubble suppressing the proliferation of harmful algae and removing heavy metals has been introduced through a lot of papers and research results, and a detailed explanation of the principle is omitted.

The present invention may further include a cooling unit for lowering the temperature of the gas through heat exchange on the gas supply unit 150, for example, the gas inlet pipe 151. In this case, the cooling unit may be a refrigerant circulation type cooling water single unit including a compressor in which a refrigerant circulates in an outer appearance, and is formed of a double pipe, and a semiconductor type cooling water which is formed by zigzagging the gas inlet pipe 151 and having Peltier elements stacked on both sides thereof It can be single.

In this case, the gas to be sucked is made low in temperature and introduced into the first and second bubble generators 110 and 120 to increase oxygen saturation during mixing with the fluid, while the temperature of the nano bubbles to be discharged or discharged To lower the surrounding water temperature and thereby to inhibit the diffusion of harmful algae (which can not propagate at lower temperatures).

Also, in the present invention, the discharge tube 123 may be configured to multistage a plurality of tubes having different diameters in a slidable state, and to insert an elastic body between the tube ends.

If the pressure is applied to the tip of the small tubular body inserted into one end of the large tubular body by increasing the power of the driving unit M to increase the discharge or discharge intensity of the nano bubble, The elastic body S located between the one end of the elastic body S contracts and the tube having a small diameter is pulled out to extend the length, so that the nano bubbles can be discharged farther.

The present invention is characterized in that the second bubble generator 120 is excluded so that the partition wall 141 which is the end finishing portion 140, the car body 142 and the gas discharge pipe 2 153 ) May be combined.

In this case, it is possible to provide a low-cost device with a reduced size and efficiency of the nano bubble generator 100, so that the consumer can select the product as needed.
