The present invention relates to a vortex fluid mixing reactor and a high-efficiency ozone dissolving apparatus using the same, and more particularly, to expand the gas-liquid interface and to increase the number of contact and at the same time the water by the microbubble formation and the continuous synergy of vortex and turbulence. By increasing the residence time of ozone, the ozone dissolution efficiency is increased to 95% or more, and the waste and sewage treatment efficiency is increased, so the required ozone input amount is reduced, and the initial investment cost and energy for the ozone generator can be saved. As the ozone dissolution efficiency is maximized, the existing 60-minute ozone contact residence time can be drastically reduced to less than 3 minutes, so it can be applied to large-capacity waste and sewage treatment, and it is economical and can reduce the amount of ozone generation. A high efficiency ozone dissolving device.

In general, ozone treatment system is applied as a third advanced treatment device for advanced treatment of BOD, COD, E. coli sterilization, color removal, and odor removal in wastewater, sewage and sewage treatment. It is applicable to sewage treatment plants or sewage treatment plants with less than 5,000 ~ 10,000 tons per day, but large capacity sewage treatment plants with more than 100,000 tons per day requires expensive large-capacity ozone generators and huge civil structures. Although the third advanced treatment performance by ozone is very good, it is not applicable.

In addition, the pressurized injection method, which has been used for swimming pool water treatment, is used by pressurizing the pressure in the ozone reactor to 3kg / cm ² or more, and the pressure difference (△ p) before and after the injector should be about 1.5 to 2kg / cm ² . Pressurized injection pumps should be 5 to ⁶ kg / cm ^{2 high} lift pumps.

Therefore, if this technology is applied to sewage treatment of more than 100,000 tons per day, it will not be able to afford a large capacity pump and electric power ratio.

Accordingly, it is urgent to develop a low lift pump of ^{1 to 2} kg / cm ² and a high-efficiency ozone dissolving device that can be processed under a commercial pressure, and also has an ozone dissolution efficiency of 60 to 70% and an ozone contact time based on an existing diffuser type. This 60 minutes was difficult to apply to large-capacity waste, sewage treatment plants over 100,000 tons per day.

An object of the present invention for solving the above-mentioned problems is to widen the gas-liquid interface and to increase the number of times of contact and at the same time increase the ozone residence time than water by the formation of fine bubbles and the continuous synergy of vortex and turbulence. As the efficiency of waste and sewage treatment is increased by increasing the melting efficiency to more than 95%, the required amount of ozone input is reduced, which saves the initial investment cost and energy for the ozone generator, and the existing method as the ozone melting efficiency is maximized. It is possible to significantly reduce the 60-minute ozone contact residence time to less than 3 minutes, and to provide a large volume waste and sewage treatment, thereby providing a vortex fluid mixing reactor that can reduce the amount of ozone generation and a high-efficiency ozone dissolving device using the same. .

Vortex fluid mixing reactor of the present invention for achieving the above object, the reaction tank is formed with an inlet pipe on the lower side so that the mixed fluid mixed with ozone, waste, sewage flows into the interior; Partition plates for partitioning the inside of the reaction tank in the upper and lower stages to form a plurality of spaces; A plurality of pieces are coupled to each partition plate to communicate the respective spaces, thereby moving the mixed fluid introduced into the inlet pipe to the uppermost space, and protruding a predetermined length to the lower side of the partition plate to form an ozone layer by protruding length. Mixing fluid upper transfer pipe to increase the residence time of the ozone more; And an ozone treated water discharge pipe for discharging ozonated treated water moved to the uppermost space of the reactor to the outside and an ozone discharge pipe formed at the top of the reactor to discharge ozone separated from the ozone treated water. do.

In addition, the high-efficiency ozone dissolving device of the present invention comprises: ozone dissolving means for receiving waste and sewage stored in a sump tank by a pressure pump and mixing waste, sewage and ozone into a continuous gas-liquid collision of vortex and turbulence; A turbulent spray nozzle connected to one side of the ozone dissolving means and having a turbulent spray tube having a plurality of nozzle holes formed therein to separate and spray the turbulence of the mixed fluid passing through the ozone dissolving means; A vortex fluid mixing reactor connected to one side of the turbulent jet nozzle and increasing the residence time of ozone in the mixed fluid passing through the turbulent jet nozzle to increase ozone dissolution efficiency and separating and discharging ozone treated water and ozone; It is connected to the ozone discharge pipe of the vortex fluid mixing reactor, characterized in that it comprises a ozone radiator separation device for separating the water passed with ozone.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Fig. 7 is a cross-sectional view showing a vortex fluid mixing reactor and an ozone degassing device in the high efficiency ozone dissolving device according to the present invention, and Fig. 7 is a cross-sectional view showing the ozone water separator in the high efficiency ozone dissolving device according to the present invention.

First, the vortex fluid mixing reactor 500 according to the present invention will be described together with the description of the high efficiency ozone dissolving apparatus 1 to be described below.

As shown, the high-efficiency ozone dissolving device 1 according to the present invention is largely ozone dissolving means 300 (sliding injector, vortex mixer, impact spray nozzle), turbulent spray nozzle 400, vortex fluid mixing reactor 500 , The ozone degassing apparatus 550, the ozone degassing apparatus 600, and the destroyer 700.

The ozone dissolving means 300 receives waste and sewage stored in the sump tank 100 by the pressure pump 200 and mixes the waste, sewage and ozone into a continuous gas-liquid collision of vortex and turbulence.

Here, the pressure pump 200 uses a booster pump or a self-suction pump depending on the site conditions, the head is 18 ~ 22mH or so. Conventional pressurized injector pumps have to use high lift pumps at 50 to 60 mH.

The ozone dissolving means 300 is composed of a sliding injector 310, a vortex mixer 320, a collision spray nozzle 330.

First, the sliding injector 310 is formed with a plurality of inclined turning nozzles 312 at the inlet side (6 in the drawing) at the inlet side so that the waste and sewage supplied from the pressure pump 200 causes swirl flow. At the same time, one main nozzle 313 is formed at the center, and an ozone inlet 314 is formed at one side to receive ozone from the ozone generator 315.

In addition, a passage 311 is formed inside the sliding injector 310. The passage cross-sectional area of the portion where the waste, sewage and ozone are mixed in the passage 311 is narrowly formed, thereby increasing the flow velocity in the portion. Ozone can be sucked through the ozone inlet 314.

Accordingly, in the sliding injector 310, the inhaled water and ozone rapidly turn into a swirling flow and are pulverized like a mist to be in an emulsion state, thereby maximizing ozone dissolution efficiency.

At this time, the front and rear stage pressure difference (Δp) of the sliding injector 310 should be maintained at ¹ to 1.5kg / cm ² or more, it is preferable that the gas-liquid ratio of water and ozone is 10% or less.

Next, the vortex mixer 320 is connected to one side of the sliding injector 310 and has two spiral plate springs 321 therein to form vortices and turbulence in the mixed fluid passing through the sliding injector 310. A plurality of pairs are installed in pairs, but the rotation directions of each other are repeatedly installed in a forward direction and a reverse direction. Therefore, a gaseous fluid collides while the mixed fluid of water and ozone introduced through the sliding injector 310 repeats the forward and reverse rotations. It is mixed and absorbed by the pulverizing action, and the ozone is finely divided into 2 ⁿ .

Here, the pair of helical plate springs 321 used two helical plate springs 321, the diameter of which is reduced toward the direction facing each other.

In addition, since the turbulent flow guide plate 322 is formed between the forward spiral plate spring 321 and the reverse spiral plate spring 321 to collect the mixed fluid toward the center, the mixed fluid is dispersed and collected. That is, the gas-liquid mixture is maximized by the continuous interaction between the vortex and the turbulence.

In addition, the impingement nozzle 330 is connected to one side of the vortex mixer 320 and the nozzles for injecting toward both ends inwardly so as to quantify the mixed fluid passing through the vortex mixer 320 in front ( 331 is coupled to one side, the outlet 332 is formed to match the impingement mixed fluid to supply to the turbulent jet nozzle (400).

The outlet of each nozzle 331 is preferably to reduce the diameter in order to increase the flow rate to increase the impact effect, to maximize the ozone dissolution efficiency by the front collision of the mixed fluid.

The turbulent jet nozzle 400 is connected to one side of the collision jet nozzle 330 of the ozone dissolving means 300 and passes through the collision jet nozzle 330 to separate / spray the turbulence of the mixed fluid again. The turbulent injection pipe 410 having a plurality of nozzle holes 411 is provided therein.

That is, the turbulent jet nozzle 400 has a structure in which the turbulent jet pipe 410 is inserted / combined inside a tube with a central side of the tube, and the nozzle hole 411 of the turbulent jet pipe 410 has a mixed fluid. It is formed to be inclined in one direction so that the vortex is formed by turning the inside of the turbulent injection nozzle 400 in one direction.

In addition, the sum of the size of all the nozzle holes 411 is preferably equal to or smaller than the inlet size of the turbulent injection pipe 410 (about 80 to 100%).

On the other hand, the turbulent injection nozzle 400 has a turbulent injection pipe 410 having a nozzle hole 411 therein to serve as a strainer function.

The vortex fluid mixing reactor 500 is connected to one side of the turbulent jet nozzle 400 and increases ozone dissolution efficiency by increasing the residence time of ozone in the mixed fluid that has passed through the turbulent jet nozzle 400. It separates and discharges ozone treated water and ozone.

In other words, the conventional pressure dissolving device is based on Henry's Law for forcibly dissolving gas by applying a pressure of 3 to ⁵ kg / cm ^{2 in} the reactor to increase the dissolution efficiency of ozone gas. There was a problem of polluting the surroundings due to a lot of power and natural degassed in the ozone treatment tank and effluent.

Therefore, in the present invention, instead of breaking the conventional stereotypes and dissolving the gas into the liquid by the reverse idea, instead of finely splitting, the method by the double diaphragm snow so that the gas is absorbed into the liquid at the gas-liquid interface. In this case, since there is no need to pressurize, there is an advantage that the electric energy is greatly reduced, and since it is dissolved by natural principle at normal pressure, there is no worry of secondary ozone pollution because excess dissolved ozone is not degassed in ozone treated water. none.

The vortex fluid mixing reactor 500 includes a reaction tank 510 having an inlet pipe 511 formed at a lower side thereof so that a mixed fluid having passed through the turbulent jet nozzle 400 is introduced therein;

A partition plate 520 partitioning the inside of the reaction tank 510 in multiple stages up and down to form a plurality of spaces 520a;

A plurality of partitions are coupled to each of the partition plates 520 to communicate the respective spaces 520a to move the mixed fluid introduced into the inlet pipe 511 to the uppermost space 520a. A mixed fluid upper transfer pipe 521 for increasing the residence time of ozone than water by forming an ozone layer 525 by protruding a predetermined length below the protruding length;

Ozone treated water discharge pipe 512 for discharging the ozonated treated water moved to the uppermost space 520a of the reactor 510 to the outside and ozone formed at the top of the reactor 510 is separated from the ozone treated water. Consists of the ozone discharge pipe 513 to discharge to the ozone water separator 600.

Here, the inlet pipe 511 is preferably eccentrically installed to one side of the reaction tank 510 to form a swirl flow in the mixed fluid introduced through the inlet pipe 511.

The mixed fluid upper transfer pipe 521 is pivotally coupled to the partition plate 520 in one direction to move the mixed fluid introduced into the lower portion of the reaction tank 510 through the inflow pipe 511 to the uppermost space 520a. By forming a flow, the ozone dissolution efficiency is increased by increasing the vortex.

In addition, the remaining partition plate 520 except for the uppermost partition plate 520 includes ozone and some mixed fluids remaining in the upper ozone layer 525 based on the partition plate 520. An ozone / mixed fluid return tube 522 is returned to the interior.

That is, the mixed fluid flowing into the lower portion of the reaction tank 510 through the inlet pipe 511 and moving to the uppermost space 520a through the mixed fluid upper transfer pipe 521 is located in each of the upper and lower spaces 520a. In the temporary storage, the water surface of the mixed fluid is up to the lower end of the mixed upper transfer pipe 521, so that the ozone gas separated from the water stays in the ozone layer 525 above the water surface of the mixed fluid.

Accordingly, some of the ozone gas remaining in the ozone layer 525 is dissolved again in water, and the other is mixed in the lower space () through the ozone / mixed fluid return pipe 522 together with some mixed fluid. By increasing the vortex while recycling into the fluid, the ozone dissolution efficiency is increased.

As such, the basic principle that the vortex fluid mixing reactor 500 has excellent ozone dissolution efficiency even at normal pressure is that the residence time of water and ozone gas can be different and can be adjusted.

That is, the conventional pressurized injection reactor is forcibly pressurized and dissolved at the same time so that water and ozone are discharged at the same time, so the residence time of water and ozone is the same and cannot be adjusted. Because of the longer residence time, the ozone dissolution efficiency is 10 to 20 times higher than that of the pressure dissolving device.

For example, if the gas-liquid ratio is 10%, if the residence time of water is 1 minute, the residence time of ozone gas into which only 1/10 of the water is injected is 10 minutes, and if the gas-liquid ratio is 5%, it is 20 minutes. Therefore, the ozone dissolution efficiency is improved by the difference in residence time.

In addition, the ozone treatment water discharge pipe 512 has an inlet located in the uppermost space 520a, and the outlet is vertically extended downward from the inlet, and is bent to the outside of the reaction tank 510, that is, The outlet of the ozonated water discharge pipe 512 is preferably located below the inlet side so that the ozone treated water can flow downward.

In addition, a strainer network 512b is provided at an inlet side of the ozone treatment water discharge pipe 512 to remove foreign substances, and a mixed fluid overflows into the ozone treatment water discharge pipe 512 at the lower end of the strainer network 512b. The hat shade 512a is installed to be introduced.

On the other hand, the reactor 510 is preferably the upper hard plate 510a is detachably coupled to the upper end so as to clean the foreign matter caught in the strainer network (512b).

In addition, an ozone degassing apparatus 550 is installed in the reactor 510 to separate excess ozone that is not completely dissolved in the ozone treated water.

The ozone degassing apparatus 550 is made by installing a plurality of beads 551 in a predetermined section of the ozone treatment water discharge pipe 512, and the perforated network 552 above and below the plurality of beads 551. It is installed to accommodate the beads 551.

Therefore, when the ozonated water flows downward through the inlet of the ozonated water discharge pipe 512, the ozonated water passes through the plurality of stacked round beads 551 (diameter 20 to 30 mm), that is, In addition, the ozone treated water flows around the surface of the round bead 551, and a thin film is formed so that the excess ozone which is not completely dissolved is degassed and separated.

Here, it is preferable that the pressure should not be applied downstream of the ozone degassing apparatus 550 or the water should be filled to give a drop. Therefore, it is preferable that the diameter of the ozone treatment water discharge pipe 512 is made about 120% larger than the inlet pipe 511 of the reaction tank 510.

The ozone separated by the ozone degassing device 550 is moved upward and discharged through the ozone discharge pipe 513.

In addition, the ozone ozone separator 600 is connected to the ozone discharge pipe 513 of the vortex fluid mixing reactor 500 and separates water that has passed with ozone.

The ozone ozone separator 600 is connected to the ozone discharge pipe 513 of the vortex fluid mixing reactor 500, the inlet 611 is formed so that ozone is introduced into one side, the water is removed at the top A pure water ozone discharge port 612 is formed to discharge pure ozone, and a tank 610 formed with a drain pipe 613 at which water is separated from ozone at the bottom thereof;

A plurality of water separation balls 620 for separating water from ozone and installed between the upper and lower perforation networks 621 in the tank 610;

The tank 610 is provided with a plurality of spaced apart from each other at a predetermined interval on the upper perforated network 621 inside the ozone discharge holes (630a) (631a) is formed alternately at the edge and the center of the separation ball ( The water separation plate 630 (631) for separating the water again with respect to the ozone passed through 620.

In addition, a protruding portion 613a protruding the drain tube 613 inwardly is formed at an inner lower end of the tank 610, and an ozone is prevented from being discharged to the drain tube 613 above the protruding portion 613a. The blocking plate 614 is formed so that the edge thereof has a larger diameter than the protrusion 613a and is bent / extended below the end of the protrusion 613a.

That is, since the lower end of the blocking plate 614 is located below the water surface, ozone is prevented from being discharged through the drain pipe 613.

On the other hand, the water temporary storage unit 615 is installed on the upper side of the water separation plate 630, 631 to separate the water again with respect to ozone discharged through the pure ozone outlet 612. The temporary storage unit 612 opens the upper end of the tank 610 and then discharges the stored moisture.

Thus, ozone water separator 600 is to increase the life of the ozone decomposition heater (not shown) of the destroyer 700 to be described below by separating and discharging the excess water with ozone.

In addition, a destroyer 700 having an ozone decomposition heater (not shown) is provided at one side of the ozone dewatering device 600 so as to thermally destroy the pure ozone passing through the ozone water separating device 600. Is installed.

Hereinafter, the operation of the high-efficiency ozone dissolving device according to the present invention will be described.

Waste and sewage stored in the sump tank 100 is introduced into the sliding injector 310 by the pressure pump 200, and at the same time, the ozone gas produced by the ozone generator 315 is also passed to the ozone inlet 314 of the sliding injector 310. Inflow. At this time, the water flowing into the sliding injector 310 passes through the turning nozzle 312 and the main nozzle 313 to form a rapid swirling flow with ozone to be crushed like a mist and the emulsion after the vortex mixer 320 Will be moved to.

The mixed fluid moved to the vortex mixer 320 repeats the forward rotation and the reverse rotation while passing through the forward / reverse spiral plate spring 321, and the gas-liquid is mixed and absorbed by the collision and the crushing action. It will split. In addition, the mixed fluid is collected and dispersed by the turbulence induction plate 322 in the process of passing between the spiral plate spring 321 to maximize the gas-liquid mixture by the continuous interaction of the vortex and the turbulence. .

Subsequently, the mixed fluid having passed through the vortex mixer 320 is divided into two, flows into the nozzles 331 provided at both ends of the collision spray nozzle 330, collides with the front face, and is then mated again to form the turbulent spray nozzle 400. Will be moved to.

The turbulence of the mixed fluid introduced into the turbulent jet pipe 410 of the turbulent jet nozzle 400 after the frontal collision by the collision jet nozzle 330 is inclined through the nozzle hole 411 of the turbulent jet pipe 410. It is separated / injected again, causing swirling flow. In this process, the foreign matter contained in the mixed fluid is filtered by the turbulence jet pipe 410.

The mixed fluid passing through the turbulent jet nozzle 400 flows into the inlet pipe 511 of the vortex fluid mixing reactor 500.

The mixed fluid introduced into the lower portion of the vortex fluid mixing reactor 500 causes swirling flow while passing through the mixed fluid upper feed pipe 521 of each partition plate 520 installed up and down to move to the uppermost space 520a. At this time, the ozone gas separated from the water in each space 520a is to stay in the ozone layer 525 under each partition plate 520, and a part of the ozone gas remaining in the ozone layer 525 is dissolved again in water. The rest is recycled into the mixed fluid in the lower space 520a through the ozone / mixed fluid return pipe 522 together with some mixed fluid to increase the vortex.

Therefore, when the mixed fluid passes through the vortex fluid mixing reactor 500, the ozone dissolution efficiency is maximized because the residence time of ozone gas is considerably longer than water.

Subsequently, the ozonated treated water in the vortex fluid mixing reactor 500 is discharged to the outside through the ozone treated water discharge pipe 512, and ozone separated from the ozonated water is discharged to the ozone discharge pipe 513. Through the ozone separation unit 600 is moved through.

Here, the foreign matter contained in the ozonated water passing through the ozonated water discharge pipe 512 is filtered by the strainer network 512b, and the ozone treated water falling along the ozonated water discharge pipe 512 is degassed in the ozone zone. Through the round bead 551 of the device 550, the ozone treated water flows around the surface of the round bead 551, a thin film is formed, the excess ozone that is not completely dissolved is degassed and separated.

The ozone separated in this way is moved to the ozone separator separation apparatus 600 through the ozone discharge pipe 513.

In addition, the ozone moved to the ozone separation device 600 separates the water contained in the ozone while passing through the water separation ball 620, and the separated water is the drain pipe at the bottom of the tank 610. Ozone gas is discharged to the outside through 613 and the water is separated again while passing through the water separation plates 630 and 631 to discharge the pure ozone through the pure ozone outlet 612.

The pure ozone discharged to the ozone water separator 600 is moved to the destroyer 700 and thermally destroyed by the ozone decomposition heater of the destroyer 700.
