Description

Degas for manufacturing of gas / liguid mixing ozone solution watar

The present invention relates to an apparatus for producing gas / liquid mixed ozone dissolved water, and more particularly, dissolving gas such as ozone oxygen in sewage or wastewater, which is treated water, to obtain a high concentration of dissolution efficiency and maximized dissolution rate. The present invention relates to an apparatus for producing gas / liquid mixed ozone dissolved water that can be reused as drinking water or heavy water by filtering ozone remaining in the wastewater and various heavy metals and inorganic matters.

Recently, the technology related to the domestic and foreign environmental industry has been advanced so that BOD, SS, and COD treatments have been researched and developed in the water treatment field so that there is no problem, and now, in the stage of effectively removing nitrogen (TN) and phosphorus (TP), In order to prevent water-borne infectious diseases due to the disinfection problem in water purification treatment of water supply, it is at the point where advanced treatment of sewage, sewage, and wastewater is being reused for water resources that are gradually depleted and depleted. The situation requires more advanced processing.

Conventional gas dissolving device for advanced treatment of sewage or wastewater developed to solve this problem is air diffusion type gaseous gas in which air, pure oxygen or ozone is introduced into the treated water using a porous diffuser. (Ozone) dissolving unit; It is roughly classified into two types of mechanical gas (ozone) dissolving devices having a structure in which water is disturbed to dissolve air in the atmosphere.

That is, ozone dissolved water uses strong oxidizing power to disinfect, sterilize, and decompose or harm the contaminants in water, and the oxidation treatment plays an important role in water treatment. For example, the complete oxidization of harmful organic substances changes to carbon dioxide (CO₂), water (H₂O), nitrogen (N₂) gas, etc., and water-soluble metal ions such as iron (Fe + ²) and manganese (Mn + ²) are insoluble hydroxides. And BOD and COD are also decomposed into CO 2 or H 2 O by ozone and treated.

Among the apparatuses for making ozone dissolved water, the conventional air diffusion type gas-based gas dissolving device has a disadvantage of low dissolution efficiency. Recently, a mixture of an ejector method or a static mixer method is used. It was developed by injecting bubbles into a constant water tank. Unlike conventional acid method, it can get high concentration of dissolved water, but it is frequently blocked in ejector or static mixer part during the pretreatment of wastewater. There are too many problems.

In addition, there is a problem in that the treatment water discharge concentration is irregular and the amount of ozone is increased due to the vortex phenomenon in the unstable tank because there is no device for preventing the vortex in the tank reaction tank.

In addition, the dissolution efficiency is slightly improved, but the length of the treatment device is longer, which takes up a lot of installation place.When the pressure pump method is bonded to this method, the dissolution efficiency is relatively high. It is difficult to increase the capacity by the existing method alone and there is a problem of low stability of the solution.

And mechanical gas dissolving device is divided into two kinds of water stirring and surface stirring, both of which dissolve air or gas in water by drastically changing the contact area of gas and water by introducing air into the water stirred by impeller. It is. However, this method is also insufficient to obtain high concentration dissolution efficiency of air or gas.

Therefore, the present invention was developed to improve the performance by improving and supplementing the existing dissolution device in order to solve the conventional problems as described above, the object of the present invention is to develop to enable the dissolution of oxygen or other gases. In addition, the present invention provides an apparatus for preparing gas / liquid mixed ozone dissolved water, which can reduce high power maintenance costs or machine maintenance costs according to operation, and further enhance gas dissolution efficiency and stability.

The first step: primary air / liquid mixture ozone dissolved water (hereinafter referred to as "first ozone dissolved water") in which ozone gas is dissolved in the treated water by mixing and mixing ozone gas into the treated water during the process of pumping and circulating the treated water in the intake tank. Generation step (S210);

Second step: Secondary air / liquid mixed ozone dissolved water (hereinafter referred to as “secondary ozone dissolved water”) in which ozone gas is added to the primary gas / liquid dissolved water generated in the above step to replenish and dissolve ozone. Generation step (S220);

The third step: making the bubble particles of the secondary ozone dissolved water produced in the step into a micro bubble by a screw-type impeller rotating at high speed into the pressurized melt reaction tank of the pressurized method, and then between the inner / outer cylinder of the pressurized melt reaction tank Zigzag to increase the contact area with the secondary ozone dissolved water and prolong the residence time and stabilize the vortex to increase the ozone dissolution rate to a high concentration (S230);

Fourth step: Ozone treatment step (S240) for collecting and treating the ozone gas discharged from the pressurized lysis reaction tank separately to discharge to the atmosphere;

Step 5: Part of the secondary ozone dissolved water in which ozone is dissolved at high concentration in the pressurized lysis tank is recycled to the intake tank, and the remaining part is passed through the ozone lysis reaction tank to the final treatment tank and the first and second pressurized filtration tanks. Final treatment water filtration and discharge step of using as a discharge or heavy water re-use during the process of repeated circulation (S250); Consists of

Hereinafter, a process of making ozone dissolved water by the above steps using the apparatus for preparing gas / liquid mixed ozone dissolved water of the present invention will be described.

2 is a process chart of the gas / liquid extrusion dissolution reaction system in which the present invention is carried out, in the gas / liquid mixed extrusion process system of the present invention, the intake tank 10 stores treated water for generating dissolved gas, and The treated water of the water intake tank 10 is pumped along the line by the primary pressure pump 20 and injected into the injection nozzle 31 of the first ejector 30.

FIG. 5A is a structural diagram of the first ejector, in which the injection nozzle 31 and the discharge pipe 34 are spaced apart from each other in the tank 32 of the first ejector 30, and an ozone inlet port is formed at one side of the tank 32. 33) is formed. Therefore, in the tank 32, when ozone is mixed by the pressure when the treated water is injected from the injection nozzle 31 to the discharge pipe 34, primary ozone dissolved water is produced and discharged.

4 is an internal structural diagram of the gas / liquid mixture extruder used in the present invention, and the primary ozone of the first ejector 30 is located at one side of the gas / liquid secondary mixture 41 of the gas / liquid mixture extruder 40. An inlet 42 through which dissolved water flows is formed, and a gas inlet 43 through which ozone gas is introduced is formed at the other side.

In the gas / liquid secondary mixture cylinder 41 and the lower case 45, the melted water of the gas / liquid secondary mixture cylinder 41 is rotated at a high speed by the motor 44 through the through hole 48. A hollow shaft 46 introduced into the inside is installed, and a screw type impeller 47 having a discharge hole 49 is installed at an end of the hollow shaft 46 exposed to the lower portion of the case 45, and the impeller ( The hollow shaft 46 and the case 45 including 47 are assembled into the inner cylinder 51 of the pressure melting reaction tank 50 described below.

Therefore, the primary ozone dissolved water that is ejected from the first ejector 30 always flows into the gas / liquid secondary of the gas / liquid mixture extruder 40 before it flows into the inner cylinder 51 of the pressure-dissolving reaction tank 50. Firstly introduced into the mixing cylinder 41, and the ozone gas introduced through the gas inlet 43 is supplementally mixed again to make the secondary ozone dissolved water of the second step.

When the impeller 47 of the gas / liquid mixture extruder 40 rotates at a high speed, the lower end thereof becomes a vacuum state, and thus the secondary ozone dissolved water generated in the gas / liquid secondary mixture 41 is a hollow shaft 46. Through the screw-type impeller 47 that rotates at high speed, the bubble particles are once again broken into fine bubbles and introduced into the pressure-dissolving reaction tank 50.

3 is an internal structural diagram of the pressure lysis reaction tank in the system of the present invention, the pressure lysis reaction tank 50 is a plurality of inclined plate (53a) 53b on both sides between the inner / outer cylinder (51, 52) Towards each other in a zigzag-facing state is installed, the upper end is formed with an ozone exhaust pipe 55 connected to the ozone inlet (63) of the second ejector (60).

In this pressurized lysis reaction tank 50, while the contact area with the dissolved ozone water is maximized, the dissolution rate of ozone is faster, and the dissolved solution is pressurized because the pressurized lysis reaction tank 50 is also pressurized. The ozone concentration of ozone dissolved water is about 10 ~ 15mg / l, and the dissolution reaction takes place, which is much different from the method of increasing the gas dissolution rate through the static mixer as in the conventional dissolution method. It's a better way.

That is, the inclined plates 53a and 53b zigzag downwardly between the inner / outer cylinders 51 and 52 are ozone dissolved water extruded from the gas / liquid mixture extruder 40 into the inner cylinder 51. 51) (52), when it is raised through the stable immersion of the ozone dissolved water, and the gas / liquid mixture extruder 40 acts like a static mixer during the operation of the pressure melting reaction tank ( Continuous circulation along the inclined plates (53a) (53b) of 50 can achieve a higher concentration of dissolution rate.

In other words, the inclined plates 53a and 53b extend the contact residence time of ozone drastically while increasing and decreasing the flow of ozone dissolved water in the direction of the arrow as shown in FIG. In this case, the turbulence is changed to laminar flow and stabilized. Therefore, the dissolution effect is several times higher than the dissolution effect of the conventional static mixer, which stabilizes the flow of dissolved ozone water and dissolves the gas in the liquid at a high concentration.

5B is an internal structural view of the second ejector of the present invention, wherein the second ejector 60 having the ozone inlet 63 formed at one side of the tank 62 is a secondary pressure pump 70 of the intake tank 10. When the treated water is injected from the injection nozzle 61 to the discharge pipe 64, the ozone introduced through the ozone inlet 63 is mixed and mixed into the ozone collecting tank 80 in the intake tank 10 in a mixed state. After being treated, it is processed in the ozone treatment unit 81 so as to be released into the atmosphere.

Therefore, in spite of the above process, the gas (ozone) which is not dissolved or incompletely dissolved in the pressurized lysis reaction tank 50 is separated from the dissolving liquid and then discharged through the second ozone exhaust pipe 55 through the upper ozone exhaust pipe 55. 60 is sent to the ozone inlet 63 and collected into the ozone collection tank 80 in the intake tank 10, and then the gas of incomplete dissolution is treated in the ozone treatment unit 81 and then released into the atmosphere.

And one end of the discharge line of ozone dissolved water treated in the pressurized lysis reaction tank 50 is connected to the ozone lysis reaction treatment tank 90 and the other end of the discharge line is connected to the intake tank 10 is configured to be recycled. The ozone dissolved water overflowed from the ozone dissolution reaction treatment tank 90 is then introduced into the final treatment tank 100 which is the next treatment tank.

The final treatment water tank 100 is provided with first and second pressure filtration tanks 110a and 110b for sequentially filtering the dissolved ozone water supplied through the pressure filtration pump 111 and the second pressure filtration tank ( Ozone dissolved water passed through 110b) is recycled to the final treatment tank (100).

Here, the first pressure filtration tank 110a is composed of a filtration tank combining sand, zeolite, and ceramic particle media, and the second pressure filtration tank 110b is preferably composed of an AC filter filtration tank. When the first and second pressure filtration tanks (110a, 110b) in order to pass through the residual ozone is very effectively removed and complete purification process can be completely removed to chromaticity, pathogens, and other foreign matter.

And the final treated water filtered in this way is to be used as a discharge or heavy water material is recycled to the final treatment tank 100, if necessary, the ozone dissolved water manufacturing apparatus of the present invention, unlike other existing treatment apparatus It has the following features.

First: the secondary ozone dissolved water generated in the pressure lysis reaction tank 50 is recycled to the intake tank.

Second: Repeated recycling of the final treated water filtered in the pressure filtration tanks 110a and 110b is performed.

Third: By using special method of inclined plate stabilization method, more powerful and high concentration of dissolved gas can be produced than other methods, and more reliable and stable treated water can be produced.

Therefore, the dissolved gas produced by the present invention can be utilized as reused water such as heavy water or beverage, and can be utilized in various industrial fields depending on the dissolved gas, and the dissolved ozone is used for final treatment of water and sewage, marine products, It can be used in various fields such as fishing, livestock, agriculture, medical, semiconductor optics, sterilization, color and odor removal.

As described above, the present invention allows gas and liquid to be injected at the same time as passing the treated water of the intake tank in the first ejector, and mixes ozone to the treated water in such ejector to make the gas / liquid dissolution reaction first. In the liquid mixing extruder to make the second more powerful dissolution, the structure is simple, the installation cost is low, and the process is simple to reduce the processing cost.

Therefore, the conventional process structure for introducing the nozzle into the water or the conventional mechanical gas dissolution method has problems such as cavitation, the installation of the shield plate is essential for efficient dissolution, so the overall process is complicated and the installation cost increases In order to solve the problem, gas and liquid injection are separated, and the gas / liquid dissolution efficiency can be significantly enhanced compared to the conventional method of only mixing the primary.

In addition, the ozone dissolved water extruded by a screw-type impeller rotating at high speed when the ozone dissolved water is extruded into the lower extruding port of the gas / liquid mixture extruder is dispersed into very small micro bubbles, so the contact area is maximized to increase the dissolved efficiency. Rotating the liquid-extruder at high speed increases the vortex of the water, but the present invention has the effect of producing a high concentration of dissolved gas because the zigzag inclined plate forms water and stabilizes the laminar flow.
