The column type ultrafine bubble reactor 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. As shown in fig. 1 to 5, a tower type ultrafine bubble reactor 1 according to an embodiment of the present invention includes a body 10, a primary bubble breaker 102, and a secondary bubble breaker 103.
The body 10 is provided with a reaction chamber 101, and the wall of the reaction chamber 101 is provided with a through hole, a liquid inlet 104, an air inlet 105, a circulating gas outlet 106, a circulating liquid outlet 107 and a liquid outlet 108. A part of the primary bubble breaker 102 passes through the through hole and extends into the reaction chamber 101, wherein the primary bubble breaker 102 has a circulating liquid inlet 1021, a circulating gas inlet 1022 and a gas-liquid mixture outlet 1028, the circulating liquid inlet 1021 is communicated with the circulating liquid outlet 107, and the circulating gas inlet 1022 is communicated with the circulating gas outlet 106. The secondary bubble breaker 103 has a feed port communicating with a gas-liquid mixture outlet 1028 and a discharge port 1033.
The operation of the column type ultrafine bubble reactor 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 5. Fresh feed liquid is added to reaction chamber 101 from inlet 104 and gas is added to reaction chamber 101 from inlet 105 until the desired pressure is reached in reaction chamber 101. The feed liquid in the reaction chamber 101 is pumped out from the circulating liquid outlet 107 and is driven by the pump to enter the primary bubble breaker 102. Advantageously, the feed liquid may be heat exchanged before entering the primary bubble breaker 102.
Meanwhile, since the high-speed circulation feed liquid forms a negative pressure in the primary bubble breaker 102, the high-speed circulation feed liquid brings the circulation gas into the primary bubble breaker 102 and mixes and shears the circulation gas to generate a large amount of bubbles, so as to form a gas-liquid mixture. Specifically, the recycle gas exits the reaction chamber 101 through the recycle gas outlet 106 and enters the primary bubble breaker 102 through the recycle gas inlet 1022.
The gas-liquid mixture is ejected from the gas-liquid mixture outlet 1028 of the primary bubble breaker 102 and enters the secondary bubble breaker 103, the gas-liquid mixture rotates at a high speed in the secondary bubble breaker 103, and due to the density difference, the gas gathers near the axis of the secondary bubble breaker 103, is compressed and sheared by the liquid to generate a large amount of ultrafine bubbles having a diameter of 50 μm or less, and is ejected from the discharge port 1033 of the secondary bubble breaker 103 and enters the reaction chamber 101. The smaller the diameter of the bubble, the lower the rising speed of the bubble in the liquid. Therefore, the reaction chamber 101 is filled with a large amount of ultra fine bubbles to form an emulsion, so that the reaction can be rapidly performed.
The tower-type ultrafine bubble reactor 1 according to the embodiment of the present invention is provided with the secondary bubble breaker 103 connected to the primary bubble breaker 102, so that the mechanical energy of the gas-liquid mixture ejected from the primary bubble breaker 102 can be sufficiently utilized to convert the mechanical energy of the gas-liquid mixture ejected from the primary bubble breaker 102 into the surface energy of bubbles, so that bubbles having a diameter of 2mm in the gas-liquid mixture are changed into ultrafine bubbles having a diameter of 50 μm or less. Compared with the gas-liquid interfacial area of the existing gas-liquid reactor, the gas-liquid interfacial area of the tower type ultrafine bubble reactor 1 according to the embodiment of the invention can be increased by more than 40 times under the same input power.
Moreover, the smaller the diameter of the bubble is, the higher the mass transfer coefficient of the bubble is, so that the reaction efficiency of the tower type ultrafine bubble reactor 1 can be greatly improved. Therefore, the tower type ultrafine bubble reactor 1 provided by the embodiment of the invention has the advantages of high mass transfer efficiency, high reaction rate, low energy consumption and the like, and can greatly shorten the reaction time and reduce the size of the reactor.
As shown in fig. 1 to 3, the ratio of the height to the diameter of the reaction chamber 101 is 3 to 20. A circulating gas outlet 106 is provided on the ceiling of the reaction chamber 101, and a liquid inlet 104 and a gas inlet 105 are provided on the upper portion of the side wall of the reaction chamber 101. As reaction product is withdrawn from circulating liquid outlet 107, feed liquid may be replenished through liquid inlet 104 in order to maintain a steady level of liquid in reaction chamber 101. The gas is supplemented through the gas inlet 105 to stabilize the pressure in the reaction chamber 101.
The circulating liquid outlet 107 is arranged on the side wall of the reaction chamber 101, and the circulating liquid outlet 107 is positioned below the liquid inlet 104 and the gas inlet 105. Advantageously, the wall of the reaction chamber 101 is further provided with a liquid outlet 108, and the liquid outlet 108 is arranged at the central position of the bottom wall of the reaction chamber 101.
In some embodiments of the present invention, as shown in fig. 1-3, the tower type ultrafine bubble reactor 1 further comprises an overflow baffle 109, the overflow baffle 109 is disposed on the wall of the reaction chamber 101 and adjacent to the circulating liquid outlet 107, and the upper edge of the overflow baffle 109 is located above the circulating liquid outlet 107. Thereby the structure of the tower type superfine bubble reactor 1 can be more reasonable.
Specifically, the overflow baffle 109 comprises a horizontal plate welded to the wall of the reaction chamber 101 and a vertical plate welded at its lower edge to the horizontal plate and at its upper edge above the circulating liquid outlet 107
As shown in fig. 1 to 5, the primary bubble breaker 102 includes a suction chamber 1023, a mixing tube 1024, and an injection tube 1026. The suction chamber 1023 has a circulation gas inlet 1022, the injection pipe 1026 has a circulation liquid inlet 1021, and a nozzle 1025 is formed at an end of the injection pipe 1026, and the nozzle 1025 extends into the suction chamber 1023. The mixing tube 1024 communicates with the suction chamber 1023, and a front port of the mixing tube 1024 is fitted with the nozzle 1025. The mixing tube 1024 has a gas-liquid mixture outlet 1028.
Specifically, the front end of the injection tube 1026 is opened to form a circulation liquid inlet 1021, and the suction chamber 1023 may be located outside the reaction chamber 101 (as shown in FIG. 1, the injection nozzle 1025 is located outside the reaction chamber 101, respectively). A portion of the mixing tube 1024 is located within the reaction chamber 101 (shown in fig. 1). The circulating liquid flows from the front end of the injection pipe 1026 to the rear end of the injection pipe 1026.
In one embodiment of the present invention, as shown in fig. 1-2, the tower type microbubble reactor 1 further comprises fixing ribs 1027. One end of the fixing rib plate 1027 is disposed on the inner wall of the reaction chamber 101, and the other end of the fixing rib plate 1027 is disposed on the outer wall of the mixing pipe 1024. Whereby the primary bubble breaker 102 can be more securely mounted on the body 10.
Advantageously, there are a plurality of fixing rib plates 1027, and there are 2-6 fixing rib plates 1027 distributed along the axis of the primary bubble generator 102.
Each of the suction chamber 1023, the injection tube 1026, and the mixing tube 1024 is horizontally disposed.
As shown in fig. 1 to 2, the suction chamber 1023 includes a front section 10231 and a rear section 10232 connected to each other, a circulation air inlet 1022 is provided on a side wall of the front section 10231, a cross-sectional area of the front section 10231 is constant in a front-rear direction, and a cross-sectional area of the rear section 10232 is reduced from a front to a rear direction.
Wherein the rear end of the rear section 10232 is open and connected to the front end of the mixing tube 1024, and the nozzle 1025 protrudes into the suction chamber 1023 through the front wall of the suction chamber 1023. Advantageously, the nozzle 1025 is adjacent to the mixing tube 1024. More advantageously, the nozzle 1025 is located in front of the mixing tube 1024.
As shown in fig. 1 to 4, in a specific example of the present invention, the injection tube 1026 includes a cylindrical portion and a circular truncated cone portion connected to the cylindrical portion. The ratio of the diameter of the cylindrical part to the minimum diameter of the circular table part is 2-6: 1, the cone apex angle of the circular table part is 20-80 degrees. Wherein the dome is configured as a nozzle 1025.
The circulating liquid enters the injection pipe 1026 through the circulating liquid inlet 1021, and is injected from the nozzle 1026 to form a high-speed liquid. The high-speed liquid forms a negative pressure in the suction chamber 1023 to suck the circulation gas into the suction chamber 1023. Since the nozzle 1025 is fitted to the mixing tube 1024, i.e., the nozzle 1025 is opposite to the mixing tube 1024 and in front of the mixing tube 1024, the high-speed liquid brings the circulating gas into the mixing tube 1024 and mixes and shears to generate a large number of bubbles so as to form a gas-liquid mixture.
As shown in fig. 1-2, the cross-sectional area of the mixing tube 1024 remains constant in the front-to-back direction. Advantageously, a gas-liquid mixture outlet 1028 is provided on a side wall of the mixing tube 1024 adjacent to a rear end of the mixing tube 1024.
As shown in fig. 3-5, in some examples of the invention, the secondary bubble breaker 103 includes a connecting tube 1031 and a receiving chamber 1032. A first end of the connection pipe 1031 is connected to the gas-liquid mixture outlet 1028. The feed and discharge ports 1033 are provided on the wall of the accommodation chamber 1032.
The accommodation chamber 1032 is provided with discharge ports 1033 at first and second axially opposite ends thereof. In other words, a first end of the accommodating chamber 1032 is opposite to a second end of the accommodating chamber 1032 in the axial direction of the accommodating chamber 1032, and the discharge port 1033 is disposed at each of the first end and the second end of the accommodating chamber 1032. Wherein, the second end of the connecting pipe 1031 is connected with the feed inlet, and the length direction of the connecting pipe 1031 is tangent to the circumference of the accommodating chamber 1032.
Since the length direction of the connection pipe 1031 is tangential to the circumferential direction of the accommodation chamber 1032, the gas-liquid mixture ejected from the primary bubble breaker 102 (i.e., the gas-liquid mixture ejected from the mixing pipe 1024) enters the accommodation chamber 1032 tangentially through the connection pipe 1031, whereby the gas-liquid mixture can be made to rotate at a high speed in the accommodation chamber 1032. Due to the difference in density, the gas collects near the axis of the housing chamber 1032, and is compressed and sheared by the liquid to generate a large number of ultrafine bubbles having a diameter of 50 μm or less (advantageously, 50 μm or less). The liquid containing the ultrafine bubbles is ejected from the discharge ports 1033 at both ends of the accommodation chamber 1032 and enters the reaction chamber 101. Since the smaller the diameter of the bubble, the lower the rising speed of the bubble in the liquid, the reaction chamber 101 is filled with a large amount of ultrafine bubbles to form an emulsion, thereby enabling the reaction to proceed quickly.
In one example of the present invention, the housing 1032 may be a swivel body. The structure of the secondary bubble breaker 103 can thereby be made more rational. The rotation bus of the accommodating cavity 1032 can be a circular arc line, and the rotation bus of the accommodating cavity 1032 can also be a straight line parallel to the axis of the accommodating cavity 1032 and a curve formed by two straight lines. In addition, the rotation generatrix of the housing chamber 1032 may be a curve composed of a straight line parallel to the axis of the housing chamber 1032 and two circular arc lines. Advantageously, the straight line parallel to the axis of the housing cavity 1032 is tangent to the two circular lines at their intersection.
As shown in fig. 5, the feed port is located in the middle of the housing chamber 1032 in the axial direction of the housing chamber 1032, and the cross-sectional area of the housing chamber 1032 decreases from the middle of the housing chamber 1032 to the end of the housing chamber 1032. Specifically, the cross-sectional area of the accommodating chamber 1032 decreases from the middle of the accommodating chamber 1032 to the first end of the accommodating chamber 1032, and the cross-sectional area of the accommodating chamber 1032 decreases from the middle of the accommodating chamber 1032 to the second end of the accommodating chamber 1032. The structure of the secondary bubble breaker 103 can thereby be made more rational. Advantageously, the cross-section of the connection pipe 1031 is a flat rectangular structure, thereby minimizing resistance generated when the gas-liquid mixture enters the accommodation chamber 1032.
Advantageously, the housing 1032 is symmetrical with respect to a cross section passing through the axial center of the housing 1032. The structure of the secondary bubble breaker 103 can thereby be made more rational.
