Description

Technical Field

[0001] This invention relates to the field of environmental protection technology, and in particular to an oxidation device for enhancing the treatment of toxic wastewater. Background Technology

[0002] Chemical industry wastewater is characterized by its high toxicity, recalcitrant nature, and multi-component coupled toxicity, presenting key challenges such as "overlapping toxicity profiles," "synergistic toxicity from multiple factors," and "inhibition of conventional microbial reaction chains." Therefore, a process principle of "reducing toxicity first, followed by regeneration treatment" is necessary. Current conventional physicochemical treatment methods focus solely on removing visible indicators such as COD, color, and SS, neglecting the reduction of wastewater toxicity. This can easily lead to frequent poisoning of subsequent biological systems, production shutdowns, and difficulties in microbial community recovery. Therefore, there is an urgent need for supporting biological pretreatment equipment, and ozone oxidation tanks are a typical choice—relying on the catalytic oxidation of ozone, they can effectively destroy the stable molecular structure of toxic organic matter, achieving the dual goals of reducing wastewater toxicity and improving biodegradability, thereby ensuring the stable operation of subsequent biological systems. A raw water tank is usually connected to the ozone oxidation tank. The raw water tank can store chemical multi-polluting wastewater to be treated and is a water storage unit that stably supplies the pre-treated water to the ozone oxidation tank. After the wastewater inside is pressurized by the booster pump, it is fully mixed with the ozone gas delivered by the ozone generator and then transported to the ozone oxidation tank for catalytic oxidation treatment. The connecting pipe on the ozone oxidation tank and the connecting pipe on the raw water tank are usually connected by flanges. This has the disadvantages of complicated disassembly and assembly procedures, high requirements for the flatness of the flange sealing surface, and easy leakage due to seal aging or loose bolts.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1, referring to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides an oxidation device for enhancing the treatment of toxic wastewater. The oxidation device for enhancing the treatment of toxic wastewater includes a main component 1 and a connecting component 2. The two components work together to facilitate pipeline connection and enhance its sealing performance.

[0027] The main component 1 includes an ozone oxidation tank 11, one end of which is connected to a first connecting pipe 12, one end of which is provided with a second connecting pipe 13, and one end of which is connected to a raw water tank 14.

[0028] An ozone generator is also installed on one side of the ozone oxidation tank 11. The wastewater from the raw water tank 14 is pressurized by a booster pump and fully mixed with the ozone gas delivered by the ozone generator before entering the ozone oxidation tank 11 through two connecting pipes. One end of the raw water tank 14 is connected to a booster pump.

[0029] The ozone oxidation tank 11 is the core reaction equipment. Through the thorough mixing of ozone and wastewater and the catalytic effect of the catalyst inside the tank, it can efficiently degrade the recalcitrant toxic organic matter in the wastewater, reduce the toxicity of the wastewater and improve its biodegradability. The first connecting pipe 12 and the second connecting pipe 13 are used to transport the gas-liquid mixed wastewater to be treated, so that the water in the raw water tank 14 is transported to the inner wall of the ozone oxidation tank 11 through the dual pipelines, ensuring the uniformity of water distribution. The wastewater in the raw water tank 14, pressurized by the booster pump, is thoroughly mixed with ozone gas delivered by the ozone generator. It then enters the tank through the first connecting pipe 12 and the second connecting pipe 13. After being evenly dispersed by the water distributor, it comes into full contact with the catalyst packed in the tank. The catalyst promotes the decomposition of ozone to generate highly oxidizing hydroxyl radicals (OH). Through the synergistic effect of the non-selective oxidation of hydroxyl radicals and the direct oxidation of ozone, the stable molecular structure of toxic organic matter in the wastewater, such as benzene rings and heterocycles, is destroyed, and they are degraded step by step into small molecule organic acids, and finally mineralized into carbon dioxide, water and inorganic ions, thus achieving the treatment goal of reducing wastewater toxicity and improving its biodegradability.

[0030] This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand its working principle.

[0031] The connecting component 2 is disposed on the first connecting pipe 12 and includes a connector 21. The first connecting pipe 12 includes a movable plate 211 disposed on the first connecting pipe 12. A support plate 212 is fixed to one end of the movable plate 211, and a pressing plate 213 is fixed to one end of the support plate 212. A roller 214 is disposed on the inner wall of the pressing plate 213.

[0032] There are four sets of connectors 21.

[0033] A positioning post is fixed on the first connecting pipe 12. When it is necessary to connect the two connecting pipes, the positioning post on the second connecting pipe 13 is aligned with the positioning hole and inserted to connect the first connecting pipe 12 and the second connecting pipe 13. Then, the four moving plates 211 are moved. The movement of the moving plates 211 drives the support plate 212 to move. The movement of the support plate 212 drives the pressing plate 213 to move synchronously. The movement of the pressing plate 213 drives the roller 214 to move. The movement of the roller 214 can press the second connecting pipe 13, so that the second connecting pipe 13 is firmly aligned with the first connecting pipe 12, ensuring the stability of the connection.

[0034] Example 2, refer to Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the connecting component 2 also includes a support member 22. The support member 22 includes a support column 221 inserted into the inner wall of the roller 214. A support block 222 is fixed to the outside of the support column 221. One end of the support block 222 is fixed to the extrusion plate 213.

[0036] The support column 221 is used to support the roller 214, and the support block 222 is used to support the support column 221.

[0037] A turntable 223 is provided on one side of the first connecting pipe 12, and a groove 223-1 is provided on the inner wall of the turntable 223.

[0038] By rotating the turntable 223, the turntable 223 rotates the slide groove 223-1, which in turn squeezes the extrusion shaft 224, thereby driving the moving plate 211 to move. The moving plate 211 drives the support plate 212 to move in conjunction, which in turn pushes the extrusion plate 213 and the roller 214 to move synchronously. The roller 214 applies extrusion pressure to the outer wall of the second connecting pipe 13, so that the second connecting pipe 13 and the first connecting pipe 12 fit tightly together, ensuring the stability of the connection. Through the connection of the two connecting pipes, the raw water tank 14 is connected to the ozone oxidation tank 11.

[0039] An extrusion shaft 224 is inserted into the inner wall of the chute 223-1, and one end of the extrusion shaft 224 is fixed to the moving plate 211.

[0040] Rotating the turntable 223 synchronously drives the slide 223-1 to rotate. During rotation, the slide 223-1 exerts a squeezing effect on the extrusion shaft 224, thereby driving the moving plate 211 to move. The moving plate 211 drives the support plate 212 to move in conjunction, which in turn pushes the extrusion plate 213 and roller 214 to move synchronously. The roller 214 applies extrusion pressure to the outer wall of the second connecting pipe 13, making the second connecting pipe 13 fit tightly with the first connecting pipe 12, ensuring the structural stability of the connection. After the two connecting pipes are connected, the pipeline between the raw water tank 14 and the ozone oxidation tank 11 is connected.

[0041] The turntable 223 has a slot 223-2, and a block 225 is provided in the slot 223-2. A fixed shaft 226 is inserted into the inner wall of the block 225. A torsion spring 227 is sleeved on the outside of the fixed shaft 226. One end of the torsion spring 227 is fixed to the block 225, and the other end is fixed to the fixed shaft 226.

[0042] In the initial state, the turntable 223 continuously applies pressure to the locking block 225, causing the locking block 225 to compress the torsion spring 227 and maintain a stored force. When the pipeline needs to be connected, the turntable 223 is rotated, which synchronously drives the locking groove 223-2 and the sliding groove 223-1 to rotate. When the locking groove 223-2 rotates to the edge of the locking block 225, the rebound force of the torsion spring 227 pushes the locking block 225 to precisely engage with the locking groove 223-2, realizing the positioning and locking of the turntable 223. At the same time, the sliding groove 223-1, which rotates synchronously with the turntable 223, drives the subsequent actuator to move, thereby completing the docking and limiting fixation of the two connecting pipes.

[0043] Example 3, referring to Figures 4-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0044] Specifically, the connecting component 2 also includes a seal 23, which includes a sealing ring 231 disposed within the first connecting pipe 12.

[0045] Except for the sealing ring 231, there are four of each of the other sealing components 23.

[0046] After the two connecting pipes are connected, the wastewater from the original water tank 14 is transferred through the two connecting pipes by the booster pump. The impact force of the wastewater during transportation enhances the sealing performance of the sealing ring 231, which can effectively prevent leakage at the connection of the two connecting pipes and improve the safety and stability of pipeline operation.

[0047] A fixing frame 232 is fitted on the outside of the sealing ring 231. One end of the fixing frame 232 is fixed to the inner wall of the first connecting pipe 12, and a compression ring 233 is fixed to one end of the sealing ring 231.

[0048] The fixing frame 232 is used to protect the sealing ring 231 and prevent the sealing ring 231 from being damaged.

[0049] The impact force during wastewater transportation will cause the squeezing ring 233 to move. The movement of the squeezing ring 233 will drive the sealing ring 231 to move and fit with the connection of the two connecting pipes, thereby achieving self-reinforcing sealing and effectively preventing leakage at the pipe connection.

[0050] One end of the compression ring 233 is provided with a movable column 234, a connecting rod 235 is provided on one side of the movable column 234, and a movable strip 236 is provided on one side of the connecting rod 235. The movable strip 236 is inserted into the inner wall of the fixed frame 232 and moves.

[0051] The impact force generated during wastewater transport pushes the moving strip 236 to displacement, which in turn squeezes the connecting rod 235. The connecting rod 235 has beveled ends, which exert a squeezing effect on the bottom of the moving column 234 during its displacement. A positioning sleeve is fixed to the surface of the moving column 234, and the inner wall of the positioning sleeve is inserted into the positioning strip fixed to the inner wall of the fixed frame 232. The positioning sleeve can slide along the outer side of the positioning strip. After being squeezed, the moving column 234 moves along the direction of the positioning strip, thereby pushing the squeezing ring 233 to displacement. The squeezing ring 233 then causes the sealing ring 231 to fit tightly against the pipe connection.

[0052] An expansion plate 237 is provided on one side of the movable strip 236.

[0053] There are four expansion plates 237.

[0054] The impact force of the wastewater will squeeze the four expansion plates 237, causing one end of the expansion plates 237 to lift up. The movement of the expansion plates 237 will squeeze the moving strip 236, which in turn will squeeze the connecting rod 235. The connecting rod 235 will squeeze the moving column 234. The movement of the moving column 234 will drive the compression ring 233 to move. The compression ring 233 and the sealing ring 231 will move and fit together with the connection of the two connecting pipes, achieving self-reinforcing sealing and effectively preventing leakage at the pipe connection.

[0055] A positioning post 238 is inserted into the inner wall of the expansion plate 237, and one end of the positioning post 238 is fixed to the fixing frame 232.

[0056] The positioning post 238 is used to support the expansion plate 237, which rotates outside the positioning post 238 when it moves.

[0057] During use, when connecting, align the positioning hole of the second connecting pipe 13 with the positioning post and insert it to complete the initial connection of the two pipes. Then, rotate the turntable 223, which synchronously drives the slide groove 223-1 and the slot 223-2 to rotate. During the rotation of the slide groove 223-1, the extrusion shaft 224 inserted into the inner wall is squeezed, driving the four sets of moving plates 211 to move synchronously, thereby driving the support plate 212, the extrusion plate 213 and the roller 214 to move together. The roller 214 applies extrusion force to the outer wall of the second connecting pipe 13, so that the two pipes fit tightly together. At the same time, the locking block 225, which is initially squeezed by the turntable 223 and compressed by the torsion spring 227, precisely engages with the slot 223-2 with the rebound force of the torsion spring 227 when the slot 223-2 rotates to the corresponding position, realizing the positioning and locking of the turntable 223, ensuring the stability of the pipe connection, and finally completing the pipe connection between the raw water tank 14 and the ozone oxidation tank 11. After the pipeline connection is completed, the booster pump pressurizes and transports the wastewater in the original water tank 14. The impact force of the wastewater first acts on the four expansion plates 237 in the fixed frame 232, causing one end of the expansion plate 237 to lift and squeeze the moving strip 236. After the moving strip 236 is displaced, it squeezes the connecting rod 235 with inclined structure at both ends, thereby pushing the moving column 234 to slide along the positioning strip direction. During the movement of the moving column 234, it squeezes the compression ring 233, causing the sealing ring 231 to fit tightly with the connection of the two connecting pipes. With the impact force of the wastewater transportation, the sealing performance is self-reinforced, effectively preventing leakage problems at the pipeline connection.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
