Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and more specifically, to a wastewater ozone catalytic oxidation device. Background Technology

[0002] Currently, there are not many feasible technologies for advanced wastewater treatment: activated carbon adsorption, other chemical adsorbents, Fenton process (an advanced oxidation process), membrane processes, and aerated biological filters, etc., each have their own advantages and limitations. In comparison, catalytic ozone oxidation is a green process. Activated carbon adsorption has good water treatment effects, but besides its high cost, the main problem is the need for regenerating approximately 0.01% waste carbon, making activated carbon regeneration a challenge. Other chemical adsorbents require acid or alkali for desorption, resulting in desorption solutions with a concentration of 3- 5% COD removal is also a challenge. The Fenton process, a high-level oxidation method, has a relatively good effect on organic matter removal, but with the addition of ferrous sulfate at dosages exceeding 1000 ppm, along with hydrogen peroxide and liquid alkali, only about 100 ppm of COD is removed. Sludge and salt production are becoming increasingly problematic. Membrane processes and aerated biological filters both have their limitations. In principle, the catalytic ozone process and the Fenton process oxidize organic matter in the same way, relying on •OH, but the pathways for generating •OH differ. The Fenton process relies on Fe2+ to catalyze H2O2 under acidic conditions, which is homogeneous catalysis. This not only requires the addition of chemical reagents but also produces large amounts of iron sludge and sulfuric acid after neutralization. The root cause is that ozone catalysis relies on "transition metal compounds," and the catalyst is solid-phase, heterogeneous catalysis, a true catalyst. Moreover, it catalyzes under neutral pH conditions, without producing sludge or salt. Although ozone is a strong oxidant that can oxidize many kinds of organic matter, oxidation does not mean complete oxidation. It oxidizes large organic molecules into small organic molecules such as alcohols, aldehydes, and organic acids, but the organic matter is not removed, and the TOC value does not even change. Moreover, ozone cannot directly oxidize many kinds of organic matter in biological wastewater. Numerous experiments have shown that direct ozone oxidation only achieves a COD removal rate of 10-20% for most biological wastewater effluents. However, after catalysis, ozone decomposes to produce •OH, which not only has a stronger oxidizing ability but also oxidizes a wider variety of organic matter.

[0003] After the pretreated organic wastewater is put into the catalytic oxidation tower, the organic wastewater and granular sludge layer are stirred and mixed by a stirrer. At the same time, water is sprayed from the bottom of the granular sludge layer through a water distributor to mix the organic wastewater and granular sludge layer, so as to achieve anaerobic treatment of wastewater. However, during operation, the organic wastewater and granular sludge layer can easily cover the oxygen catalytic gas outlet, causing nozzle blockage and affecting the wastewater treatment efficiency. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a wastewater ozone catalytic oxidation device. An oxygen pump is connected to an oxygen catalytic gas inlet pipe to introduce catalytic gas, allowing oxygen to flow into the interior of a gas exhaust ring and exit through bubble outlet slots inside the gas exhaust ring, generating bubbles that catalyze the wastewater. Simultaneously, an airflow booster ring is installed on the inner wall of the gas exhaust ring, positioned on one side of the bubble outlet slot. This reduces the diameter of the bubble outlet slot, pressurizing the oxygen catalytic gas as it flows out, resulting in denser bubbles and increased contact with the wastewater, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wastewater ozone catalytic oxidation device, comprising a reinforced support base, a protective plate fixedly connected to the top of the reinforced support base, a bubble guide support inner ring provided on the inner wall of the protective plate, a connecting head provided between the protective plate and the bubble guide support inner ring, a connecting nut fixedly connected inside the connecting head, a fixing nut threadedly connected to one end of the connecting nut, and a reinforcing keel strip fixedly connected to the bottom of the bubble guide support inner ring.

[0006] In a preferred embodiment, there are multiple sets of connectors, connecting nuts, and fixing nuts, and these multiple sets of connectors, connecting nuts, and fixing nuts are arranged in a ring array about the outer wall of the inner ring of the bubble guide support.

[0007] In a preferred embodiment, a snap-fit ​​ring is fixedly connected to the outer wall of the inner ring of the bubble guide support, a matching ring is fixedly connected to the joint between the reinforced support base and the protective plate, and a pressure-resistant support column is fixedly connected between the snap-fit ​​ring and the matching ring.

[0008] In a preferred embodiment, the number of reinforcing keel strips is multiple sets, and the multiple sets of reinforcing keel strips are arranged in a circular array about the bottom of the inner ring of the bubble guide support.

[0009] In a preferred embodiment, a suction cup connector is fixedly connected to the top of the inner ring of the bubble guide support, and a gas exhaust ring is fixedly connected to the top of the suction cup connector. The top of the gas exhaust ring is provided with an insertion groove.

[0010] In a preferred embodiment, a supporting keel is fixedly connected inside the gas exhaust ring, and a keel bracket is fixedly connected to the outer wall of the supporting keel, with the keel bracket located inside the gas exhaust ring.

[0011] In a preferred embodiment, an airflow booster ring is fixedly connected to the inner wall of the gas exhaust ring sleeve. A bubble outlet groove is opened inside the gas exhaust ring sleeve and is located at the fitting point between the airflow booster ring and the gas exhaust ring sleeve. An oxygen catalytic gas inlet pipe is fixedly connected to the top of the insertion groove and communicates with the interior of the gas exhaust ring sleeve through the insertion groove.

[0012] The technical effects and advantages of this invention are as follows: The oxygen pump is connected to the oxygen catalytic gas inlet pipe to introduce catalytic gas, allowing oxygen to flow into the interior of the gas exhaust ring. The oxygen then exits the gas exhaust ring through the bubble outlet groove inside the gas exhaust ring, generating bubbles that catalyze the wastewater. At the same time, an airflow booster ring is set on the inner wall of the gas exhaust ring. The airflow booster ring is set on one side of the bubble outlet groove, reducing the diameter of the bubble outlet groove. This pressurizes the oxygen catalytic gas as it flows out of the bubble outlet groove, making the bubbles denser and increasing the contact with the wastewater, preventing sludge and debris from clogging the bubble outlet groove. The snap-fit ​​ring is fitted onto the bottom of the inner ring of the bubble guide support. The matching ring is snapped into the connection between the reinforced support base and the fixing nut, so that the entire pressure support column supports the snap-fit ​​ring and the matching ring, and supports the entire protective plate and the inner ring of the bubble guide support, preventing deformation of the entire protective plate and the inner ring of the bubble guide support. The reinforced support base is fixedly connected to the bottom of the protective plate. By bending the entire reinforced support base, the entire reinforced support base changes from its original parallel state to a vertical state, so that the entire protective plate and the inner ring of the bubble guide support can be supported.

The number of connecting heads 3, connecting nuts 4, and fixing nuts 5 are multiple sets, and these multiple sets of connecting heads 3, connecting nuts 4, and fixing nuts 5 are arranged in a ring array about the outer wall of the bubble guiding support inner ring 6. The outer wall of the bubble guiding support inner ring 6 is fixedly connected to... A snap-fit ​​ring 7 is provided, and a matching ring 8 is fixedly connected at the joint between the reinforced support base 1 and the protective plate 2. The fixing nut 5 is threadedly connected to the protective plate 2 and the inner ring 6 of the bubble guide support, so that the reinforced support base 1 and the inner ring 6 of the bubble guide support are initially fixed. Then, the snap-fit ​​ring 7 is sleeved on the bottom of the inner ring 6 of the bubble guide support, and the matching ring 8 is snapped into the joint between the reinforced support base 1 and the fixing nut 5, so that the pressure support column 9 supports the snap-fit ​​ring 7 and the matching ring 8, and supports the protective plate 2 and the inner ring 6 of the bubble guide support as a whole, preventing the protective plate 2 and the inner ring 6 of the bubble guide support from deforming. Refer to the instruction manual appendix Figure 1-3Furthermore, a pressure support column 9 is fixedly connected between the snap ring 7 and the matching ring 8. A reinforcing keel rib 10 is fixedly connected to the bottom of the inner ring 6 of the bubble guide support. Multiple sets of reinforcing keel ribs 10 are arranged in a circular array around the bottom of the inner ring 6 of the bubble guide support. A suction cup connector 11 is fixedly connected to the top of the inner ring 6 of the bubble guide support. A gas exhaust ring sleeve 12 is fixedly connected to the top of the suction cup connector 11. An insertion point is provided on the top of the gas exhaust ring sleeve 12. The gas exhaust ring 12 is internally fixedly connected to a support keel rib 14, and the outer wall of the support keel rib 14 is fixedly connected to a keel bracket 15. The keel bracket 15 is located inside the gas exhaust ring 12. The keel bracket 15 is indirectly set at one end of the support keel rib 14 to support the entire support keel rib 14, thereby increasing the overall strength and toughness of the gas exhaust ring 12 and preventing it from contacting foreign objects in wastewater, which could cause pitting on the surface of the gas exhaust ring 12 and affect the flow of oxygen catalytic gas. Refer to the instruction manual appendix Figure 1-3 Furthermore, an airflow booster ring 16 is fixedly connected to the inner wall of the gas exhaust ring 12. A bubble outlet groove 17 is provided inside the gas exhaust ring 12. A catalytic gas is introduced by connecting an oxygen pump to an oxygen catalytic gas inlet pipe 18, allowing oxygen to flow into the interior of the gas exhaust ring 12 and exit through the bubble outlet groove 17, generating bubbles that catalyze the wastewater. Simultaneously, an airflow booster ring 16 is provided on the inner wall of the gas exhaust ring 12. The airflow booster ring 16 is positioned on one side of the bubble outlet groove 17, reducing the diameter of the bubble outlet groove 17. This pressurizes the oxygen catalytic gas as it flows out of the bubble outlet groove 17, resulting in denser bubbles and increased contact with the wastewater. An oxygen catalytic gas inlet pipe 18 is fixedly connected to the top of the insertion slot 13, and the oxygen catalytic gas inlet pipe 18 communicates with the interior of the gas exhaust ring 12 through the insertion slot 13.

[0023] Working principle: When the equipment is in use, the fixing nut 5 is threaded to the protective plate 2 and the inner ring 6 of the bubble guide support, so that the reinforced support 1 and the inner ring 6 of the bubble guide support are initially fixed. Then, the snap ring 7 is sleeved on the bottom of the inner ring 6 of the bubble guide support, and the matching ring 8 is snapped on the connection between the reinforced support 1 and the fixing nut 5, so that the pressure support column 9 supports the snap ring 7 and the matching ring 8, and supports the protective plate 2 and the inner ring 6 of the bubble guide support, preventing the protective plate 2 and the inner ring 6 of the bubble guide support from deforming. The reinforced support 1 is fixedly connected to the bottom of the protective plate 2. By bending the reinforced support 1, the reinforced support 1 is changed from the original parallel state to the vertical state, so that the protective plate 2 and the inner ring 6 of the bubble guide support can be supported. The inner wall of the bubble guide support inner ring 6 is wavy. A suction cup connector 11 is installed at the top of the bubble guide support inner ring 6, and a gas exhaust ring 12 is installed at the top of the suction cup connector 11. When the user performs ozone catalytic oxidation on wastewater, the user connects an oxygen pump to the oxygen catalytic gas inlet pipe 18 to introduce catalytic gas, allowing oxygen to flow into the interior of the gas exhaust ring 12 and exit through the bubble outlet groove 17 inside the gas exhaust ring 12, generating bubbles to catalyze the wastewater. At the same time, an airflow booster ring 16 is installed on the inner wall of the gas exhaust ring 12, and the airflow booster ring 16 is integrally set in the bubble outlet groove 17. On the side, the diameter of the bubble outlet groove 17 is reduced so that when the oxygen catalytic gas flows out of the bubble outlet groove 17, it is pressurized, making the bubbles denser and increasing the contact with wastewater. This prevents sludge and debris from clogging the bubble outlet groove. At the same time, a supporting keel rib 14 is set inside the gas exhaust ring sleeve 12 to support the inner wall of the gas exhaust ring sleeve 12. Furthermore, a keel bracket 15 is indirectly set at one end of the supporting keel rib 14 to support the entire supporting keel rib 14, increasing the overall strength and toughness of the gas exhaust ring sleeve 12. This prevents contact with foreign objects in the wastewater, which could cause pitting on the surface of the gas exhaust ring sleeve 12 and affect the flow of oxygen catalytic gas.
