Description

Technical Field

[0001] The present invention relates to the technical field of wastewater oxidation, and in particular to a wastewater advanced oxidation device. Background Art

[0002] Advanced oxidation processes (AOPs) are a technology for treating toxic pollutants that began in the 1980s. They are characterized by the generation of hydroxyl radicals, which are highly oxidizing. These free radical reactions can effectively decompose organic pollutants and even completely convert them into harmless inorganic substances such as carbon dioxide and water. Advanced oxidation technologies are primarily categorized as Fenton oxidation, photocatalytic oxidation, ozone oxidation, ultrasonic oxidation, wet oxidation, and supercritical water oxidation.

[0003] Ozone oxidation uses ozone to oxidize and decompose wastewater. As an excellent strong oxidant, ozone is highly effective in wastewater disinfection, decolorization, deodorization, and removal of organic matter. Ozone oxidation degrades organic matter rapidly, under mild conditions, and without secondary pollution, making it widely used in water treatment. Ozone treatment of wastewater generally manifests itself through direct ozone oxidation and free radical oxidation via the formation of hydroxyl radicals.

[0004] The ozone oxidation device in the prior art can refer to the "Advanced Oxidation Device for Wastewater" of Chinese patent application No. 201911094627.7, which includes an ozone generator and a reaction tank. A gas pipe is provided between the ozone generator and the reaction tank, and the two ends of the gas pipe are connected to the ozone generator and the reaction tank respectively. The reaction tank is provided with a circulation pipe, which is connected to the reaction tank and the gas pipe respectively. The reaction tank is provided with an overflow pipe, which is equipped with a drain valve. The overflow pipe is higher than the connection between the gas pipe and the reaction tank and lower than the connection between the circulation pipe and the reaction tank. The reaction tank is provided with a blower. Ozone is allowed to participate in the reaction multiple times, effectively improving the utilization efficiency of ozone gas, achieving the effect of reducing ozone gas consumption, reducing the energy consumption of the ozone generator, and achieving the effect of saving energy. However, the existing technology has limited ways of mixing ozone and sewage, which is not conducive to the full mixing of sewage and ozone. The main reason is that ozone enters the reaction tank through the air pipe, and the sewage flows downward, and the air pipe is laid flat on a limited position in the reaction tank, resulting in the ozone sprayed from the air pipe being difficult to achieve full contact with all the sewage flowing downward in the reaction tank, which in turn leads to low efficiency of dissolving ozone in sewage, and ultimately affects the oxidation effect of ozone on sewage. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that ozone enters the reaction tank through the air pipe, the sewage flows downward, and the air pipe is laid flat on a limited position in the reaction tank, which makes it difficult for the ozone sprayed from the air pipe to fully contact all the sewage flowing downward in the reaction tank.

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0048] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0049] Example 1

[0050] Reference Figure 1-4 The wastewater advanced oxidation device includes an upstream part 1, a downstream part 2, a conduit 3, an inner positioning tube 30, a flow control member 32, an outer flow area 33 and a reset member 39.

[0051] Reference Figure 1 and Figure 2, wherein the upstream portion 1 and the downstream portion 2 have the same structure, wherein the upstream portion 1 is composed of an upper outer shell 10 and an upper spiral flow groove 11 arranged in the upper outer shell 10, the outer end of the upper outer shell 10 is connected to a water inlet pipe 12, and the conduit 3 is connected to the bottom center of the upper outer shell 10; the downstream portion 2 is composed of a lower outer shell 20 and a lower spiral flow groove 21 arranged in the lower outer shell 20, the outer end of the lower outer shell 20 is connected to a water outlet pipe 22, and the conduit 3 is connected to the top center of the lower outer shell 20. In this embodiment, both the upstream portion 1 and the downstream portion 2 adopt a spiral flow method to realize water flow. Compared with the water pipe method of the prior art, it can reduce the spatial layout, facilitate water flow, and increase the water flow distance to ensure that the ozone mixed gas is fully dissolved after dissolving in the water flow. The spiral flow direction of the upstream portion 1 is from the outside to the center, and the spiral flow direction of the downstream portion 2 is from the center to the periphery.

[0052] Reference Figure 2-Figure 4 An inner positioning tube 30 is provided in the conduit 3, and an ozone inlet is provided at the top of the inner positioning tube 30. The inner positioning tube 30 is hollow and is used for the flow of ozone mixed gas. The inner positioning tube 30 is connected to the upstream part 1. In this embodiment, the top of the inner positioning tube 30 is connected to the inner wall of the upper outer shell 10 and extends into the conduit 3. The outer diameter of the outer wall of the inner positioning tube 30 is smaller than the inner diameter of the conduit 3, and a flow area 31 is formed between the inner positioning tube 30 and the conduit 3.

[0053] Reference Figure 3-Figure 4 A flow control member 32 is provided in the conduit 3, and the flow control member 32 is rotatably sleeved on the bottom end of the inner positioning tube 30, and a plurality of driving blades 320 are provided on the outer wall of the flow control member 32. When the water flows downward, the water flow brakes the driving blades 320 to rotate. An ozone overflow port 36 connected to the inner positioning tube 30 is provided on the flow control member 32. The ozone overflow port 36 continuously outputs the ozone mixed gas downward so that the ozone mixed gas is fully dissolved in the water flow.

[0054] It should be added that a central axis 34 is provided on the top of the flow control member 32, and the central axis 34 is embedded in the inner positioning tube 30. An inverted T-shaped guide port 340 is provided on the top of the central axis 34, wherein the inverted T-shaped guide port 340 is divided into a vertical guide port and a horizontal guide port. Under normal conditions, when the central axis 34 is inserted into the inner positioning tube 30, the horizontal guide port of the inverted T-shaped guide port 340 is limited by the inner wall of the inner positioning tube 30 to prevent the ozone mixed gas from being continuously output downward. When the flow control member 32 is impacted downward by the water flow, the horizontal guide port of the inverted T-shaped guide port 340 is located below the inner positioning tube 30 to ensure the continuous output of the ozone mixed gas, and then continuously output to the water flow below it through the ozone overflow port 36.

[0055] In addition, the top outer wall of the flow control member 32 is preferably set to be a cone shape (not shown in the figure), so that the sewage water flows downward after contacting the top outer wall of the flow control member 32, that is, the top of the flow control member 32 plays the role of guiding flow and reducing impact.

[0056] Reference Figure 3-Figure 4 An extended flow area 33 is provided in the conduit 3, and the extended flow area 33 is provided on the inner wall of the conduit 3, and the driving blade 320 is located in the extended flow area 33. The outer wall of the flow control member 32 cooperates with the inner wall of the conduit 3. When the water flows downward from the conduit 3, the water first impacts the flow control member 32 and moves downward, so that the flow control member 32 moves downward. In this way, the water flows from above the extended flow area 33 to the extended flow area 33, and then flows down to the conduit below the extended flow area 33. When the water flows in the extended flow area 33, it brakes the driving blade 320 to rotate, and then brakes the flow control member 32 to rotate, so that the water flows downward in a spiral shape, which helps the ozone mixed gas to fully contact the spiral water flow when it is continuously output downward from the flow control member 32.

[0057] Reference Figure 3-Figure 4 A reset member 39 is provided in the conduit 3, and the reset member 39 is connected between the inner wall of the extended flow area 32 and the flow control member 32. When the water flow stops impacting the top of the flow control member 32, the reset member 39 causes the flow control member 32 to reset upward, and the outer wall of the flow control member 32 fits the inner wall of the conduit 3, so that the flow control member 32 can be braked to move upward when there is no water flow.

[0058] It should be noted that the reset member 39 is a pulling spring, and the flow control member 32 is braked to move up and down by pulling and contracting the spring, wherein the top of the spring can be connected to the same circular ring, which rotates within the top inner wall of the extended flow area 33.

[0059] It should also be added that: the ozone mixed gas includes atmosphere and ozone, and the ozone concentration is to adjust the content of ozone in the ozone mixed gas. In this embodiment, when the ozone concentration in the ozone mixed gas is adjusted, this embodiment also helps to mix the ozone concentration evenly after adjustment, that is, after the atmosphere and ozone with adjusted content enter the inner positioning tube 30 at the same time, they will enter the inverted T-shaped guide port 340, wherein an inner fan blade structure can be set in the vertical guide port of the inverted T-shaped guide port 340, and a threaded air guide groove is set on the inner wall of the vertical guide port. When the flow control component 32 is braked and rotated by the water flow, the central axis 34 is braked and rotated synchronously, so that the fan blade structure set in the vertical guide port is rotated, so that the atmosphere and ozone are sucked into the fan blade structure. As the fan blade structure rotates, it helps to mix the atmosphere and ozone. At the same time, the mixed gas after coming out of the fan blade structure passes through the threaded air guide groove, which further helps to mix the atmosphere and ozone.

[0060] The working process of this embodiment is as follows:

[0061] Water flows into the water inlet pipe 12 of the upstream part 1, flows along the upper spiral flow groove 11, and enters the flow area 31 formed between the guide tube 3 and the inner positioning tube 30 from the center thereof;

[0062] The flow control member 32 is braked downward by the impact of the water flow, causing the entire flow control member 32 to enter the extended flow area 33. At this time, the water flows downward between the flow control member 32 and the inner wall of the extended flow area 33, thereby causing the driving blade 320 to rotate, thereby driving the flow control member 32 to rotate. At the same time, after the water hits the driving blade 320, it causes the water to flow downward in a spiral.

[0063] The ozone mixture and water flow merge as follows: the ozone mixture enters from the top of the inner positioning tube 30 and flows downward along the inner positioning tube 30. After the flow control member 32 is braked downward by the water flow, the central axis 34 also moves downward, causing the horizontal guide port of the inverted T-shaped guide port 340 to separate from the inner wall of the inner positioning tube 30. This allows the ozone mixture to transition from the inner positioning tube 30 to the inverted T-shaped guide port 340 and then enter the top of the flow control member 32. It is continuously discharged downward from the ozone overflow port 36. After being affected by the driving blades 320, the water flow spirals downward and is fully contacted with the ozone mixture continuously output from the ozone overflow port 36. In this way, the water flow is in continuous contact with the ozone mixture during the flow process, ensuring that the entire water body is in contact with the ozone mixture and that the ozone mixture is uniformly and fully dissolved in the water body. At the same time, the spiral downward flow can further increase the contact between the ozone mixture and the water flow, further ensuring that the ozone mixture is fully in contact with the water flow.

[0064] The water flow after the ozone mixed gas and water flow merge enters the downstream part 2 from the conduit 3, and the water body dissolving the ozone mixed gas enters the downstream part 2 from the center, flows along the lower spiral flow groove 21, and finally flows out from the water outflow pipe 22.

[0065] Example 2

[0066] Based on Example 1, this embodiment further discloses a method for adjusting the overall downward flow rate of the ozone mixed gas, which is specifically set as follows:

[0067] First, refer to Figure 5 The top of the inner positioning tube 30 is threadedly connected to the upstream part 1. This connection method makes it easy to remove the inner positioning tube 30 from the conduit 3. At the same time, the threaded connection method can be used to position the bottom surface of the inner positioning tube 30 in its initial state.

[0068] Secondly, refer to Figure 5 and Figure 6A flow rate adjusting member 35 is sleeved on the central shaft 34. The flow rate adjusting member 35 includes an adjusting ring 350, a connecting rod 351, a baffle 352 and a return spring 353. The flow rate adjusting member 35 cooperates with the inner positioning tube 30 after adjusting the initial position to adjust the flow rate of the ozone mixed gas.

[0069] Reference Figure 6 , the adjustment ring 350 is slidably sleeved on the outer wall of the central shaft 34;

[0070] Reference Figure 6 , both ends of the connecting rod 351 are rotatably connected to the adjusting ring 350 and the stopper 352 respectively;

[0071] Reference Figure 6 There are multiple groups of ozone overflow ports 36, and the multiple groups of ozone overflow ports 36 are arranged axially along the central axis 34. Each group of ozone overflow ports 36 has multiple ozone overflow ports 36, and the multiple ozone overflow ports 36 in each group are arranged radially outward from the center of the central axis 34. The baffle 352 slides on the flow control member 32, and the baffle 352 controls the downward discharge flow rate of the ozone mixed gas by blocking the number of ozone overflow ports 36 in the radial direction;

[0072] It should be supplemented that: an embedded slide rail for the sliding of the blocking piece 352 is provided on the top of the flow control member 32, and the slide rail is used for the blocking piece 352 to slide stably in the slide rail.

[0073] Reference Figure 6 The return spring 353 is connected between the adjustment ring 350 and the flow control member 32 .

[0074] The flow rate regulation principle of the ozone mixed gas in this embodiment is as follows:

[0075] In the initial state, the return spring 353 is compressed.

[0076] When the water impacts the flow control member 32, it moves downward, causing the bottom end surface of the driving blade 320 to contact the bottom end of the inner wall of the extended flow area 33, thereby causing the extended flow area 33 to move to its maximum downward position. At this point, the distance between the bottom end surface of the central axis 34 and the bottom end surface of the inner positioning tube 30 is at its maximum. Under the action of the return spring 353, the top of the adjustment ring 350 is brought into contact with the bottom surface of the inner positioning tube 30. During this process, the baffle 352 is pulled toward the central axis 34 by the connecting rod 351, thereby adjusting the number of ozone overflow ports 36 in the same group that the baffle 352 blocks, thereby adjusting the flow rate of the ozone overflow ports 36 to continuously output the ozone mixed gas downward.

[0077] In this embodiment, by adjusting the distance between the bottom end surface of the central shaft 34 and the bottom end surface of the inner positioning tube 30, under the braking of the return spring 353, the number of ozone overflow ports 36 in the same group blocked by the baffle 352 is adjusted, thereby adjusting the downward flow rate of ozone from the flow control member 32.

[0078] The ozone mixed gas flow rate adjustment process in this embodiment is as follows:

[0079] After the water flow impacts the flow control member 32 , the bottom end surface of the flow control member 32 abuts against the bottom of the inner wall of the extension flow area 33 .

[0080] By rotating the inner positioning tube 30, adjusting the upper and lower positions of the inner positioning tube 30 relative to the upstream part 1, and adjusting the distance between the bottom end face of the central axis 34 and the bottom end face of the inner positioning tube 30, the number of ozone overflow ports 36 in the same group blocked by the adjusting block 352 is adjusted under the braking of the return spring 353, thereby adjusting the flow rate of the ozone mixed gas from the flow control member 32 downward.

[0081] Example 3

[0082] Based on this embodiment, in order to further strengthen the contact between the ozone mixed gas and the water flow, compared with Example 1, this embodiment allows the ozone mixed gas to enter the water flow to dissolve in the water body, thereby enhancing the dissolution effect of the ozone mixed gas. Specifically, this embodiment discloses the following features:

[0083] 1. Reference Figure 8 、 Figure 9 and Figure 10 The flow control member 32 further includes a bottom rotating portion 321 that rotates at the bottom. Preferably, a rotation groove for the bottom rotating portion 321 to rotate is provided at the bottom of the flow control member 32 .

[0084] The bottom rotating part 321 is connected to the bottom of the flow control part 32 through a rotating adjustment part. The preferred structure of the rotating adjustment part in this embodiment is as follows: a central shaft 3210 is provided on the top of the bottom rotating part 321, and a gear 1 3211 is provided on the outside of the central shaft. A fixed shaft 3212 is provided on the inner wall of the rotating groove, and a gear 2 3213 is rotatably connected to the outer wall of the fixed shaft 3212, and the gear 2 3213 is engaged with the gear 1 3211. A gear ring 3214 is fixedly connected to the inner wall of the rotating groove, and the gear ring 3214 is engaged with the gear 2 3213.

[0085] The bottom rotating portion 321 is also provided with a plurality of ozone flow outlets 322 connected to the ozone overflow port 36. The ozone flow outlet 322 in this embodiment includes a transfer chamber 3220, an upper flow outlet 3221 and a lower flow outlet 3222, wherein the upper flow outlet 3221 is connected to the top of the transfer chamber 3220, and the lower flow outlet 3222 is connected to the bottom of the transfer chamber 3220. The ozone mixed gas enters the upper flow outlet 3221 from the ozone overflow port 36, and then is discharged from the lower flow outlet 3222 through the transfer chamber 3220.

[0086] 2. Reference Figure 8 、 Figure 9 and Figure 11A guide plug ring 37 is provided below the ozone overflow port 36. The guide plug ring 37 is provided with an outer flange. The outer diameter of the outer flange is in contact with the inner wall of the extended flow area 33. The bottom surface of the inner wall of the extended flow area 33 has a limiting effect on the outer flange of the guide plug ring 37, which is helpful for the realization of the second embodiment. That is, when the outer flange contacts the bottom surface of the inner wall of the extended flow area 33, the distance between the bottom end surface of the adjustment center axis 34 and the bottom end surface of the inner positioning tube 30 is adjusted and determined.

[0087] In addition, an ozone air guide pipe 38 is connected to the bottom of the ozone flow port 322, that is, the ozone air guide pipe 38 is arranged at the outlet of the downflow port 3222, and a plurality of ozone mixing flow ports 380 with downwardly inclined openings are provided on the ozone air guide pipe 38. The downwardly inclined setting prevents water from entering the ozone air guide pipe 38. The bottoms of the plurality of ozone air guide pipes 38 are fixedly connected to the same rotating ring, and the rotating ring rotates on the top of the guide plug ring 37. That is, the structural setting of the rotating ring and the ozone air guide pipe 38 ensures the stability of the ozone air guide pipe 38, and at the same time ensures the stability of the distance between the guide plug ring 37 and the bottom rotating part 321, thereby ensuring the adjustment of the central axis 34 in the second embodiment. The distance between the bottom end face of the inner positioning tube 30 and the bottom end face is stable; at the same time, the bottom of the rotating ring rotates on the top of the guide plug ring 37 in a contact-resistant manner, wherein the top of the guide plug ring 37 can be provided with an annular rotating groove corresponding to the rotating ring. In this way, based on the action of the rotating adjustment member, when the flow control member 32 is driven to rotate by the water flow, under the action of the gear ring 3214, the gear second 3213 and the gear one 3211, the bottom rotating part 321 is driven to rotate in the opposite direction relative to the flow control member 32, so that the overall rotation direction of the ozone guide tube 38 is opposite to the rotation direction of the water flow after being diverted by the driving blade 320, further ensuring that the ozone mixed gas is in full contact with the water flow.

[0088] 3. In this embodiment, refer to Figure 8 and Figure 11 The reset member 39 is connected between the guide plug ring 37 and the inner wall of the extension flow area 33.

[0089] The working principle of this embodiment is as follows:

[0090] When the water flows through the driving blades 320 to drive the flow control member 32 to rotate, since the bottom of the rotating ring rotates on the top of the guide plug ring 37 in a contacting and resisting manner, the rotating ring, the ozone air guide tube 38 and the bottom rotating portion 321 as a whole are not easily affected by the rotation of the flow control member 32. When the flow control member 32 rotates, the gear ring 3214, the second gear 3213 and the first gear 3211 drive the bottom rotating portion 321 to rotate in the opposite direction relative to the flow control member 32. In this way, the overall rotation direction of the ozone air guide tube 38 is opposite to the rotation direction of the water flow after being diverted by the driving blades 320, further ensuring that the ozone mixed gas is in full contact with the water flow.

[0091] In addition, when the water flow rotates downward through the driving blades 320, the ozone air duct 38 can penetrate into the water flow, and through the multiple ozone mixing flow ports 380 on the ozone air duct 38, the ozone mixture is further brought into contact with the water flow, thereby ensuring that the ozone mixture is fully in contact with the water flow, further ensuring that the water flow fully dissolves the ozone mixture, and ensuring the uniformity of the dissolved ozone mixture.

[0092] The above description is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and changes can be made without departing from the principles of the present invention. These improvements and changes are also considered to be within the scope of protection of the present invention.
