Description

Agricultural sterilization device with variable plasma device {Water sterilization device with variable plasma device}

The present invention relates to an agricultural and fishery water sterilization apparatus including a variable plasma apparatus, and more particularly, to a plasma generating apparatus in the related art, the manufacturing cost is reduced by simplifying the apparatus, and the amount of plasma is changed by changing the frequency. The present invention relates to an agricultural and fishery water sterilization apparatus including a variable plasma device that adjusts and sterilizes harmful bacteria present in seawater and fresh water to increase the productivity of agriculture and fishery, and also to be used as necessary agricultural and fishery water.

In farms, medicines and sterilizers are used to keep fish healthy. Recently, many sterilization apparatuses for preventing environmental pollution have been developed. As a device for sterilizing bacteria in the water as described above in the prior art Patent Publication No. 10-2010-0003341, the water introduced from the outside or the storage water circulated in the device cotton, microfiber fiber, charcoal fiber, Water flows for primary treatment while meandering through a layer or storage case of at least one selected from silver nanofibers, ocher fibers, charcoal, sand, gravel, jade, elvan, zeolite, germanium, chitosan, and reed wood A storage water pretreatment filtration device having a partition wall and at least one selected from among ultraviolet sterilization lamps, ozone generators, and ultrasonic generators installed on the side or bottom by receiving the storage water passing through the storage water pretreatment filtration device through the partition wall are installed. Detoxification device for oxidizing and decomposing heavy metals and residual pesticides in water and sterilizing germs, and through the filter and detoxification device. To the, characterized in that consisting of the discharge pipe and the shut-off valve member to enable the external exhaust, circulation motor for circulating supply the number stored in the pre-filtering device again with water, filtered and Admiral device is disclosed.

In addition, Patent Publication No. 10-0932377 (December 16, 2009) discloses a water treatment technique using plasma as a background art of the invention, generally water treatment technology is largely physical It can be divided into chemical treatment, biological treatment and multi-stage treatment. However, a lot of researches are currently being carried out to see a better water treatment effect beyond these technologies, and a lot of research is being conducted around a so-called advanced water treatment technology. In view of the above-described types of advanced water treatment technology, there are 1) an electrochemical method, 2) water treatment technology using electromagnetism, 3) water treatment technology using ultraviolet light, and 4) water treatment technology using plasma. It belongs to the water treatment technology using, as well as harmful substances in the water as well as harmful gases and odor treatment in the air is possible.

On the other hand, the conventional water treatment technology is agglomeration treatment, ozone oxidation treatment using ozone, activated carbon adsorption to adsorb soluble organic compounds and compounds, biological treatment by microorganisms, fenton oxidation process and the like are widely used. Among them, ozone is the most commonly used, and efforts are being made to apply ozone to environmental improvement and disease prevention in workplaces such as industrial wastewater and landfill leachate. This is because ozone has a strong oxidizing power, which in theory has the potential to completely decompose organic matter into CO 2 and H 2 O and produces no by-products, but the chemical properties and decomposition mechanism of ozone are gradually revealed. It is known that the reaction between ozone and some organic matters is selective or the reaction rate is slow.

In order to overcome the shortcomings of the ozone treatment and the limitations of the conventional oxidation treatment process, advanced oxidation treatment, which is a treatment that can purify contaminated water by promoting the generation of OH radicals having much stronger oxidizing power than general oxidizing agents in water ( The Advanced Oxidation Process (AOP) is considered to be very effective for water treatment.

Advanced oxidation process goes beyond the limitation of the conventional treatment method that directly decomposes organic substances from oxidant injected directly such as ozone, hydrogen peroxide, ultraviolet ray, etc., and combines several unit processes to combine artificially oxidizing OH radicals in water. It is an advanced oxidation treatment that produces and expects water treatment effects. OH Radical is an intermediate produced during the decomposition of ozone, and has a higher redox potential difference (2.80 [V]) than ozone itself. It easily targets unsaturated hydrocarbons and aromatic compounds, and in the case of halogenated compounds, replaces halogen elements. It may also be involved in degradation via pathways. After all, the ultimate goal of AOP is to maximize the concentration of these OH Radicals.

In addition, the types of AOP that can be applied to water treatment in a complex process include O 3 / highpH, O 3 / H 2 O 2 (Peroxone), O 3 / UV, H 2 O 2 / UV, and the like. Underwater high voltage plasma discharge is being actively researched.

In addition, among the advanced water treatment technologies, water treatment technology using plasma is mainly used for removing harmful gases in the air environment field in the past as a low temperature plasma process, but unlike the conventional water treatment technology, it does not require chemical input, and the treatment process is simple, and the second pollution Recently, a new concept of water treatment technology has emerged as an advantage that does not occur, and discharges forming low temperature plasma include pulse streamer discharge, silent discharge, partial discharge, creepage discharge and corona discharge. Electric discharges for water pollutant treatment have been actively conducted in the United States, Japan, the Netherlands, the Czech Republic, Russia and Canada since the late 1980s. The generation of high voltage pulse discharges in water or on the surface initiates a variety of physicochemical processes that generate UV, shock waves, and chemically active species such as H, O, OH, and H 2 O 2 . In the gas discharge, it is known that when oxygen is present in the background gas, high concentrations of ozone and active radicals are generated and easily dissolved in water to participate in the process of removing pollutants.

In particular, when air is used as the inlet gas of the plasma generator, the main reaction equation expected in the plasma generator is as follows, and radicals such as O 3 , O, OH, H, N, and HO 2 are generated and these unstable products are secondary. By reacting with pollutants or oxygen to form peroxide or a new type of radical, a chain oxidative decomposition reaction proceeds. This oxidation reaction is a water purification, such as hardly decomposable substances, harmful gases and odors in the atmosphere, and sterilization of color and wastewater. Can be widely applied to.

At present, the plasma discharge technique for water treatment has been studied so much, and it is already proved by many academic experiments that it is very good effect when the plasma is added to the water has been recognized.

However, to date, almost all technologies are very difficult to generate plasma due to the conductivity of water when plasma is generated in water, and short-circuit prevention technology must be applied. Electrodes on the surface of the surface for water surface discharge or electrodes coated with a coating film.

These devices are difficult to install due to their large size and heavy weight, and have disadvantages due to high power consumption, high price, and difficulty in operation and maintenance.

In addition, recently, techniques for generating discharge in water using various dielectrics have been studied, but problems such as short circuit or sudden decrease in discharge efficiency due to failure to maintain stable discharge in water are still occurring.

Accordingly, Patent Publication No. 10-0932377 relates to a water purification method using a high density underwater plasma torch as a solution thereof. As described in the Abstract, a plasma reactor is introduced into water to prevent deterioration of the reactor. In the water purification method using a high density underwater plasma torch to effectively transmit plasma energy by forming a strong electric field in the water surface and water, the method has an inner diameter of 1.0 ~ 20mm, an outer diameter of 5 ~ 20mm and a thickness of 0.5 ~ 5mm A transparent quartz tube having a length longer than the diameter of phosphorus standard, a conductive discharge electrode having a diameter inserted into the transparent quartz tube to secure an inner diameter and a discharge gap of the quartz tube, and an outer surface of the transparent quartz tube Meshes that form a high-density plasma region by contacting with and concentrating the maximum potential hardness at the conductive discharge electrode Underwater including a conductive counter electrode, an electrode tip assembled on top of the transparent quartz tube to fix the conductive discharge electrode to the inner central axis of the transparent quartz tube to maintain the gap distance, and a radial torch head having a gas inlet and a high voltage cable inlet.

However, the sterilization method by the UV sterilization lamp, ozone generator, and ultrasonic generator does not exhibit sufficient and stable sterilization effect as desired in aquaculture farms, and the conventional sterilization methods using plasma are also activated in the plasma region. Radicals, gases, and the like do not have good diffusion, and the catalytic oxidation reaction does not increase as desired, so that it is difficult to easily and reliably remove environmental pollutants.

1 to 4, the agricultural, fishery water sterilization apparatus including a variable plasma device according to the present invention includes a power supply device for supplying the power required for the device; A water pump 120 receiving electric power from the power supply device 100 to introduce water; Variable plasma generating device capable of controlling and controlling the intensity of the plasma generated by adjusting the frequency of the power supplied from the power supply device 100 to generate and sterilize the water flowing through the water pump 120 200; A first connection pipe 130 having one side communicating with the water pump 120 and the other side communicating with the variable plasma generating device 200; Sterilization water storage tank 400 for storing the water discharged by sterilization by the variable plasma generating device 200; A second connection pipe 140 having one side communicating with the variable plasma generating device 200 and the other side communicating with the sterilizing water storage tank 400; A contaminant and bubble discharge device 500 disposed above the sterilizing water storage tank 400 to discharge bubbles and ozone; And a sterilizing water outlet 600 disposed under the sterilizing water storage tank 400 and discharging the sterilizing water after sterilization is completed in the sterilizing water storage tank 400.

At this time, the variable plasma generating device 200,

A quartz tube 230 having a length longer than the diameter; An air inlet 240 formed at an upper side of the quartz tube 230; A conductive first electrode 210 inserted into the quartz tube 230; A conductive second electrode 220 formed outside the quartz tube 230 to generate a plasma; And control the intensity of the plasma generated between the conductive first pole 210 and the conductive second pole 220 by controlling the frequency of the supplied power by being connected to one side of the power supply device 100 to supply power. Consists of a power frequency control device 110 that can.

Plasma can be used to remove BOD, COD, H 2 S and improve transparency. In addition, the removal and suppression of harmful bacteria such as Vibrio bacteria and fish diseases are made, and can remove the fishy smell of fish tanks, toilets, breeding sites raising livestock.

Let's look at the agricultural, fishery water sterilization process including the variable plasma device.

Water to be sterilized is introduced into the plasma generator 200 through the first connection pipe 130 using the water pump 120. The plasma generator 200 includes a quartz tube 230, an air inlet 240 formed at one side of the quartz tube 230, and a conductive first electrode 210 inserted into the quartz tube 230. ) And a conductive second electrode 220 formed outside the quartz tube 230 to form a plasma region.

Here, the difference from the conventional plasma generator 200 is that if the frequency is changed through the power frequency controller 110, the amount of plasma generated by the plasma generator 200 is changed accordingly.

A graph regarding the amount of plasma generated according to frequency can be seen through FIG. 2. By using this, the user can control the plasma generation amount by adjusting the frequency according to the amount of water to be sterilized.

The unsterilized water introduced by using the water pump 120 is first sterilized by the plasma while passing through the plasma generator 200. The bactericidal power of the plasma can be confirmed through FIG. 3, but the total coliform bacteria count before the plasma treatment is 79 and the general bacterial count is 3500, but after the plasma treatment, the bactericidal power of the plasma can be confirmed through the insignificant residual bacteria.

Thus, the ozone and OH radicals are generated by plasma while passing through the quartz tube 230 in which the conductive first electrode 210 is embedded in the first sterilized water that has undergone the first sterilization process. Ozone and OH radicals are added to the primary sterilization water. Ozone and OH radicals are known for their excellent sterilization ability.

Conventionally, in order to suck air into the quartz tube 230, an air generator, a gas injector, a regulator, or the like is forcibly supplied. In addition, in order to supply ozone and OH radicals generated while passing through the quartz tube 230, water is sprayed using a bubble device or the like.

However, the present invention is configured in one step by simplifying the above two steps. In order to do so, the most important component will be the venturi tube (300).

The venturi tube 300 is one side is in communication with the lower portion of the quartz tube 230 and the other side is in communication with the side of the second connecting tube 140 is installed, forcibly forced air into the variable plasma generating device 200 At the same time as the suction supply and supply the ozone and OH radicals to the second connecting pipe (140). The venturi tube 300 sprays ozone and OH radicals generated from the quartz tube 230 to the tube through which the primary sterilizing water flows. At this time, the pressure inside the quartz tube 230 drops, so that the outside air naturally enters through the air inlet 240 formed on the top surface of the quartz tube 230.

 Therefore, the amount of ozone and OH radicals moved through the venturi tube 300 is determined by the force sucked through the venturi tube 300, that is, the output of the submersible pump, the height of the water (water pressure), etc. In this case, since a large amount of ozone and OH radicals are required, the amount of air flowing through the air inlet 240 naturally increases proportionally, and the air entering the air inlet 240 through the venturi tube 300 is increased. As the amount of increases proportionally, the amount of OH radicals generated increases proportionally.

Figure 4 shows the RNO concentration according to the air amount, it can be seen that the lower the RNO concentration increases the amount of OH radicals generated. 4, it can be seen that the greater the amount of air coming in per unit time, the greater the amount of OH radicals generated.

Secondary sterilization is performed through ozone and OH radicals supplied to the first sterilizing water through the venturi tube 300. OH radical is a kind of oxygen anion-based natural substance produced in the plasma state, which is harmless to human body and has excellent oxidation power. Research conducted in the United States shows that OH radicals have an oxidation rate 2000 times faster than ozone and 180 times faster than the sun's ultraviolet rays.

Since these OH radicals are natural substances, they do not harm the human body and help to improve the environment. The use of other chemicals to sterilize and disintegrate may harm the human body, but OH radicals do not harm the human body. Chemicals may cause secondary environmental pollution, but OH radicals have strong sterilization, deodorization and decomposition effects. It is an eco-friendly material that does not have to worry about secondary pollution.

Secondary sterilization is performed using such OH radicals and ozone, which is well known in the art.

Secondary sterilization water made up to the second sterilization is sprayed to a wide sterilization water storage tank (400). In order to mix the OH radicals and ozone remaining in the second sterilization process with the sterilization water and to discharge the bubbles and remaining pollutants generated at the same time. Above the secondary sterilizing water in the sterilizing water storage tank 400, there are pollutants such as bubbles, ozone, and foreign matter. In case of ozone, the sterilization ability is good, but if it is discharged into the air as it is harmful to human body, it must be discharged after filtering using a filter layer.

Therefore, a contaminant and bubble discharge device 500 capable of discharging bubbles and contaminants is formed at the top of the sterilizing water storage tank 400, and the activated carbon is formed at the end of the contaminant and bubble discharge device 500. The configured activated carbon filter layer 510 is formed. Ozone is filtered and discharged while passing through the activated carbon filter layer 510.

Sterilized water sterilized through the above process is used for groundwater sterilization, rainwater greening sterilization, nutrient cultivation sterilizer, seed disinfection sterilization, low pesticide substitute, plant cultivation, etc. It can be used in various fields such as sterilization, sashimi, or aquarium of seaweed, fresh water sterilizer.

In the above described with reference to the accompanying drawings in order to help understand the technical idea of the present invention, this is merely illustrative of the preferred embodiments of the present invention is not limited thereto, and the scope of the technical idea of the present invention It will be apparent to those skilled in the art that various modifications, substitutions, and the like may be made without departing from the scope of the present invention.
