In order to increase the solubility of the gas and the liquid, the gas is injected at a high pressure using an injection nozzle, or a turbulent flow is formed in the reactor. However, since the gas has a density lower than that of the liquid, it is degassed from the liquid too quickly, so there is a limit in that the treatment reaction rate, i.e., the treatment yield, is low.

Further, since the undissolved residual gas is discharged to the outside of the reactor, there is a problem that the gas consumption is large compared to the reaction rate.

1 is a schematic view schematically showing a configuration of a gas-liquid reactor 1 according to the present invention. As shown in the figure, the gas-liquid reactor 1 according to the present invention includes a reactor body 100 in which treated water B is accommodated, a bubble generator 100 for supplying MB 200).

Here, the raw water A refers to a liquid which is not mixed with the gas supplied to the initial reactor body 100, the treated water B refers to a liquid in which the gas is partially mixed although the reaction has not been completed, MBL) refers to a liquid in which the desired reaction is completed by dissolution of minute bubbles.

The gas-liquid reactor 1 according to the present invention is characterized in that the gas-liquid reactor 1 according to the present invention is characterized in that the water (MB) containing micro-bubbles containing gas in the form of microbubbles in the treated water is supplied to the treated water B to increase the contact area between the treated water B and the gas The yield can be improved and the processing time can be shortened.

The gas-liquid reactor 1 according to the present invention can be used for various purposes depending on the kind of the raw water A and the supplied gas. The raw water (A) can be used not only in water but also in various types such as lubricating oil and ethanol, and various kinds of gases can also be used.

The gas-liquid reactor (1) of the present invention is applied to a bubble column for absorption of an acidic gas, a stirrer turret for chlorination, a gravel column for ozone and water treatment, a gaseous report reactor for absorption of corals, a venturi reactor for absorption of SO ₂ , . In addition, the gas-liquid reactor 1 of the present invention can be applied to various forms, and in some cases, it can be applied to a multiphase reactor in which a catalytic reaction is required together.

The gas-liquid reactor 1 according to the present invention may further include a heat application unit (not shown) for applying heat to the reactor body 100 and a pressure application unit (not shown) for applying pressure, .

The reactor main body 100 receives the raw water A and the treated water B therein as shown in the figure. The reactor main body 100 is formed in the shape of an enclosure having a volume capable of accommodating raw water (A) and treated water (B). The reactor body 100 is formed to maintain airtightness.

The inside of the reactor main body 100 is filled with a raw water storage space 113, a treated water storage space 115, and a treated water storage tank 115 to suppress mixing of raw water A, treated water B, and mixed treated water MBL with each other. And the reaction space 117. To this end, the reactor main body 100 is provided with an upper partition 110 and a lower partition 120, respectively.

The upper partition wall 110 is formed at a predetermined length in the transverse direction at the upper portion of the reactor body 100 to block the raw water storage space 113 and the process water storage space 115 from each other. A vertical wall 111 is formed at an end of the upper partition 110 at a predetermined height.

The raw water A supplied from the raw milk inflow inlet 130 flows into the raw water storage space 113 blocked by the upper partition wall 110. The raw water A is moved upward to the treated water storage space 115 through the raw water discharge port 114 formed in the upper partition wall 110 with the water level gradually increasing in the raw water storage space 113. At this time, the flow rate of the raw water A, which is moved to the treated water storage space 115 through the raw water discharge port 114, corresponds to the flow rate of the mixed treated water MBL discharged through the mixed treated water discharge pipe 160.

The lower partition wall 120 is formed at a lower portion of the reactor body 100 to have a predetermined length in the transverse direction to separate the process water storage space 115 from the process water reaction space 117. The lower partition wall 120 forms the treated water flow passage 121 so that the treated water in the treated water storage space 115 can flow into the treated water reaction space 117 at a constant flow rate. The treated water B flowing into the treated water reaction space 117 through the treated water flow passage 121 reacts with the fine particle containing effluent MB discharged from the bubble generator 200 and is converted into the mixed treated water MBL do. The mixed process water MBL thus converted is discharged to the outside through the mixed process water discharge pipe 160.

The treated water B stored in the treated water storage space 115 remains mixed with the gas G moved through the treated water flowing path 121.

Here, it is preferable that the treated water flow passage 121 is formed to have a predetermined length in the central region of the reactor main body 100 as shown in the figure for the purpose of improving the reaction yield. However, it may be eccentrically formed on one side of the reactor main body 100 as occasion demands. At this time, the bubble generator 200 is disposed on the path through which the treated water flows into the treated water reaction space 117 through the treated water flow passage 121, and the contact between the micro- The time can be increased, which is preferable in terms of treatment yield.

The raw water inlet pipe 130, the raw water circulation pipe 140, the mixed treatment water discharge pipe 160, and the gas discharge pipe 170 are respectively connected to the reactor main body 100. The raw milk infusion inlet 130 introduces the raw water A into the raw water storage space 113. The raw water A may be provided with various kinds of liquids including water as described above.

The raw milk feed pipe 130 is connected to the raw water inlet 131 of the reactor body 100 to supply the raw water A to the bubble generator 200. At this time, the raw water inlet 131 is disposed at an upper portion of the raw water storage space 113, that is, at a position higher than the vertical partition wall 111.

The raw water circulation pipe 140 supplies raw water to the bubble generator 200 so that the microbes containing water MB is supplied to the treated water reaction space 117 of the reactor main body 100. The raw water circulation pipe 140 interconnects the raw water discharge port 141 disposed in the raw water storage space 113 and the bubble generator 200. A circulation pump 150 is provided on the path of the raw water circulation pipe 140 to provide power to move the raw water A.

Normally, circulation pump 150 may cause a malfunction when a gas is introduced into the circulation pump 150. Accordingly, the raw water circulation pipe 140 circulates the raw water A, which is a pure liquid in which the gas is not mixed. However, if the upper partition wall 110 is not formed in the reactor main body 100 and the raw water A and the treated water B are mixed and accommodated together as the case may be, That is, apart from the bubble generator 200.

The mixed treatment water discharge pipe 160 discharges the treated water B and the microbubble-like gas G contained in the microbes contained in the treated water B in the treated water reaction space 117 MBL to the outside. The mixed treatment water discharge pipe 160 is connected to the outer wall of the reactor main body 100.

The gas discharge pipe 170 discharges the gas G that has not reacted with the treated water to the outside. A gas exhaust pipe 170 is provided at an upper portion of the reactor main body 100.

The bubble generator 200 generates gas MB containing microbes by flowing gas into the raw water supplied through the raw water circulation pipe 140 and supplies it to the treatment water reaction space 117.

3 is an exploded perspective view explaining the configuration of the bubble generator 200. FIG. 4 is a cross-sectional view of the bubble generator 200, Fig.

The bubble generator 200 includes a front end nozzle 230 connected to the raw water circulation pipe 140 and a rear end nozzle 210 for spraying the MB water containing micro-scale into the process water reaction space 117 ). The shear nozzle 230 has a shear flow path 235 formed therein and a shear inlet 237 and a shear outlet 236 are formed at both ends of the shear flow path 235.

The front end inlet 237 of the shear nozzle 230 is connected to the raw water circulation pipe 140 and the raw water A introduced into the front end nozzle 230 through the front end inlet 237 is discharged through the front end discharge port 236 do. In the preferred embodiment, the diameter of the shear flow path 235 is gradually reduced. Therefore, the raw water A introduced into the shear nozzle 230 gradually decreases in diameter from the internal flow path 235, and thus the flow velocity increases as the flow direction toward the front end discharge port 236 becomes.

The rear end nozzle 210 is a cylindrical member having a rear end flow path 217 therein and has a rear end inlet port 216 and a rear end outlet port 215. The diameter of the rear end inlet port 216 is larger than the diameter of the front end outlet port 236 and the diameter of the rear end outlet port 215 is larger than the diameter of the rear end inlet port 216. Accordingly, the rear end nozzle 210 has a rear end flow path 217 whose diameter gradually increases from the rear end inlet 216 to the rear outlet 215.

Meanwhile, the front end nozzle 230 and the rear end nozzle 210 are detachably coupled to each other. 3, a protrusion 218 having a step is formed around the periphery of the rear end inlet 216 of the rear end nozzle 210. The protrusion 218 protrudes from the front end outlet 236 of the front end nozzle 230, The front end nozzle 230 and the rear end nozzle 210 may be coupled to each other.

The front end discharge port 236 of the front end nozzle 230 and the rear end inlet port 216 of the rear end nozzle 210 are spaced apart from each other by a predetermined distance so that the gas G can enter the space A gas inflow hole 213 is formed on the surface of the rear end nozzle 210. The gas inflow hole 213 is connected to the gas supply pipe 220 so that the gas G can be introduced from the outside.

When the raw water A discharged from the front end nozzle 230 flows into the rear end inlet 216 of the rear end nozzle 210 through the front end discharge port 236, 220 and the gas inflow hole 213 into the rear inlet 216. [

The raw water A and the base G which have been introduced into the rear end inlet 216 are mixed in the rear end nozzle 210 and flowed through the rear end flow path 217 to become the bubble- ). ≪ / RTI >

The microbes containing effluent MB discharged into the tail end outlet 215 flows into the treatment water reaction space 117 and reacts with the treatment water B to produce mixed treatment water MBL. The micro-bubbles generated in the bubble generator 200 are formed in a micro-sized or nano-sized form. Therefore, the area of each fine bubble contacting with the treated water B becomes larger, so that the solubility increases relatively. As a result, the mixing amount with the treated water according to the same gas supply amount is increased, and the treatment yield can be improved. In addition, the processing time can be shortened thereby.

5 is a cross-sectional perspective view illustrating the configuration of the bubble generator 200a according to another embodiment of the present invention.

The bubble generator 200 according to the preferred embodiment of the present invention may be configured such that the gas supply pipe 220 is connected to the gas inlet hole 213 of the rear end nozzle 210 so that the external gas G flows into the rear inlet port 216 .

In the meantime, the bubble generator 200a according to another embodiment of the present invention is formed with gas inflow holes 216a passing through the inner wall surface of the rear end inflow hole 216 at regular intervals. The gas inlet pipe 220a is disposed in such a manner as to surround the joint region of the front end nozzle 230 and the rear end nozzle 210. [ A gas flow path 216b is formed along the outer periphery of the front end nozzle 230 and the rear end nozzle 210,

The gas G flowing through the gas supply pipe 220 is moved along the gas flow path 216b and flows into the rear end flow path 217a through the plurality of gas inflow holes 216a. The raw water A discharged from the front end nozzle 230 and the gas G are mixed to produce bubble-like micro-scale-containing water MB and discharged to the rear end discharge port 215.

The operation of the gas-liquid reactor 1 according to the present invention having such a configuration will be described with reference to FIGS. 1 to 5. FIG.

The raw water A is introduced into the raw water storage space 113 of the reactor main body 100 through the raw milk inflow pipe 130. The water level in the raw water storage space 113 increases and the raw water A overflows to the vertical partition wall 111 and moves to the treated water storage space 115 as the raw water A continues to flow.

The raw water circulation pipe 140 connected to the raw water storage space 113 supplies the raw water A to the bubble generator 200. The raw water A is supplied to the bubble generator 200 as the circulation pump 150 is driven. The raw water circulation pipe 140 is connected to the front end nozzle 230, and the raw water A flows into the front end nozzle 230.

The raw water A introduced through the front end discharge port 236 of the front end nozzle 230 is moved to the rear end nozzle 210. The raw water A moved to the rear end nozzle 210 flows together with the gas G introduced through the air supply pipe 220 and the air inflow hole 213 and the rear end inflow hole 216 as shown in FIG. And the rear-end flow path 217, and is converted into a micro-organ containing water (MB). The fine bubbles are formed in a micro-sized or nano-sized form.

The microbes containing water MB enter the treated water reaction space 117 and the treated water B transferred to the treated water reaction space 117 through the treated water passage 121 is included in the MB containing microorganism And contacted with the micropore. The mixed treated water (MBL) thus completed is discharged to the outside through the mixed treated water discharge pipe 160.

As described above, the gas-liquid reactor according to the present invention supplies the micro-bubble reactor water mixed with the raw water in the form of micro-bubbles to the treated water. Therefore, it is possible to increase the contact area between the micro-sized bubbles and the treated water, thereby improving the treatment yield of the gas and treated water.

The treatment yield of the treated water with respect to the same gas supply amount can be remarkably improved as compared with the case where the gas is simply supplied to the conventional treatment water. In addition, the processing time can be shortened.

6 is a schematic view schematically showing the configuration of a gas-liquid reactor 1a according to another embodiment of the present invention.

The gas-liquid reactor 1 according to the preferred embodiment of the present invention as described above moves the minute bubbles MB into the treated water storage space 115 through the treated water flow passage 121 of the lower partition wall 120, 170). Accordingly, the time required for the minute bubbles MB to stay in the treated water storage space 115 is short, so that the contact time between the treated water B and the minute bubbles MB is shortened.

The gas-liquid contactor 1a according to another embodiment of the present invention includes a bubble guide plate 180 for forming a movement path for moving the minute bubbles MB between the upper partition wall 110 and the lower partition wall 120, Is formed.

The bubble guide plate 180 is coupled to the inside of the reactor main body 100, and the guide passage 181 is formed through the bubble guide plate 180. The guide passage 181 is formed on both sides of the treated water flow passage 121 so that the minute bubbles MB are diffused from the central region to the outer region of the reactor main body 100. Therefore, since the minute bubbles MB are diffused and moved throughout the treated water storage space 115, the contact time between the treated water B and the minute bubbles MB can be increased and the reaction yield can be improved.

Here, as shown in FIG. 7A, the guide passage 181 may be formed on the guide plate 180 with a predetermined width in the form of a trench. In this case, the minute bubbles MB generated in the bubble generator 200 are moved to the outer region and moved to the guide passage 181. [

On the other hand, the guide passage 181a may be formed in a circular shape having a predetermined diameter on the outer circumferential surface of the guide plate 180a as shown in FIG. 7B.

In the meantime, the gas-liquid reactor 1a according to another embodiment of the present invention includes a plurality of blocking plates 190 and 195 between the lower partition 120 and the bottom surface of the reactor body 100. The blocking plate 190 blocks the minute bubbles MB generated in the bubble generator 200 from being discharged through the mixed processing water discharge pipe 160 without being moved to the processing water storage space 115.

The blocking plates 190 and 195 are coupled to the lower portion of the bubble generator 200 to block the movement path of the minute bubbles MB. Mixed process water flow paths 191 and 196 for guiding the mixed treatment water MBL to the mixed treatment water discharge pipe 160 are formed through the plate surfaces of the first blocking plate 190 and the second blocking plate 195.

At this time, the first mixed-treatment-water flow path 191 is disposed on both sides of the bubble generator 200, and the second mixed-treatment-water flow path 196 is formed coaxially with the bubble generator 200 . Thus, the fine bubbles MB are prevented from being discharged directly to the mixed treatment water discharge pipe 160 along the straight path, and the mixed treatment water MBL is moved to the mixed treatment water discharge pipe 160.

On the other hand, FIG. 8 is a schematic view showing a configuration of a gas-liquid reactor 1b according to another embodiment of the present invention.

The gas-liquid reactor 1a according to another embodiment of the present invention described above is formed in such a manner that the guide passage of the minute bubbles MB is branched from the center to the outer peripheral region around the bubble generator 200. On the other hand, in the gas-liquid reactor 1b according to another embodiment of the present invention, the guide passage is formed in a zigzag shape from one side of the reactor main body 100 to the other side with the bubble generator 200 as a center. To this end, a plurality of guide plates 180a, 183, and 185 are coupled to the interior of the reactor body 100 in directions opposite to each other.

Thus, since the length of the guide channel becomes longer than the gas-liquid reactor 1a described above, the time required for the minute bubbles MB to stay in the treated water storage space 115 becomes longer, so that the reaction yield with the treated water B also increases .

In this case, the blocking plate 190a may also be arranged to be biased to one side of the reactor main body 100 in the same manner.

The embodiments of the gas-liquid reactor of the present invention described above are merely illustrative and those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. There will be. Therefore, it is to be understood that the present invention is not limited to the above-described embodiments. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims. It is also to be understood that the invention includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
