Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment, specifically a high-efficiency ozone dissolved gas device. Background Technology

[0002] In the field of advanced wastewater treatment and reuse, ozone oxidation technology has attracted widespread attention due to its strong oxidizing and broad-spectrum bactericidal properties. Ozone can oxidize and decompose most of the organic matter in water and kill bacteria in a short time without producing secondary pollution. It is considered an efficient and environmentally friendly water treatment method. However, especially in sewage or industrial wastewater environments, water bodies often contain suspended particulate matter, grease, flocculent matter and impurities. These factors can adversely affect the dissolution of ozone. These impurities in the water can hinder the direct contact between the gas and the water body, resulting in reduced dissolution efficiency and even the phenomenon of concentrated bubbles rising and ozone dissipation, resulting in low ozone utilization.

[0003] In the prior art, such as a high-efficiency ozone dissolution device (application number CN202022644265.9), a heating mechanism is used. In winter or when the ambient temperature is low, the oil supply pipe can be connected to a container filled with heat transfer oil, and a small oil pump can be started. Under the action of the small oil pump, the heat transfer oil can enter the heat transfer pipe through the oil outlet pipe. The spirally distributed heat transfer pipe can uniformly heat the outer shell, thereby increasing the ambient temperature inside the outer shell. This ensures that ozone still has a considerable solubility in winter or when the ambient temperature is low, thus ensuring the treatment effect on wastewater.

[0004] However, during use, when the inlet pipe passes through sewage, small impurities in the sewage are blocked by the filter screen. At this time, it needs to be removed to prevent blockage. When the filter screen is removed, the impurities will be discharged along with some sewage. If no treatment is done, the sewage will carry the floating impurities back. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency ozone dissolution device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a tank body, an inlet pipe installed on the top surface of the tank body, a drain outlet for drainage at the bottom end of the tank body, a cavity inside the tank body, a filter disc fixed inside the inlet pipe, a sewage pipe and a diversion pipe installed around the outer ring of the inlet pipe, a connecting pipe connected to the sewage pipe via a flange, and a sewage discharge structure installed inside the connecting pipe.

[0007] Preferably, the cavity is connected to a water inlet pipe and a drain outlet.

[0008] Preferably, the filter disc is inclined and made of a rigid material.

[0009] Preferably, the drain pipe is located directly above the inlet pipe, the drain pipe is inclined, and the inclination angle of the drain pipe is the same as the inclination angle of the filter disc, and the lowest point of the drain pipe is flush with the lowest point of the filter disc.

[0010] Preferably, a collection tank is screwed to the tail end of the connecting pipe. The collection tank is used to collect impurities discharged from the connecting pipe, and the connecting pipe has an obtuse "L" shaped structure.

[0011] Preferably, the sewage discharge structure includes an overflow pipe, a drain plate, and a filter screen. The overflow pipe is fixed to the outside of the connecting pipe, and an installation cap is fixed to the tail end of the overflow pipe. The installation cap is fitted onto the outside of the drain pipe and is made of a tough material. The drain plate is fixed to the inner wall of the connecting pipe and is inclined and semi-enclosed. The connection between the overflow pipe and the connecting pipe is located on the left side of the drain plate. The filter screen is fixed inside the overflow pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The high-efficiency ozone dissolved gas device proposed in this utility model allows small impurities that are not treated in time to fall onto the filter disc when wastewater passes through the inlet pipe. Due to the inclined shape of the filter disc, the impurities are continuously washed away until they move to the lowest point of the filter disc, and then move into the drain pipe. The impurities entering the drain pipe are discharged into the collection tank through the connecting pipe. Since the impurities contain some wastewater, they are discharged into the collection tank together. In order to prevent the wastewater from carrying the floating impurities back into the inlet pipe, when the wastewater rises to a certain height in the connecting pipe, the wastewater flows out from the overflow pipe and is discharged into the inlet pipe through the guide pipe. The filter screen of the overflow pipe prevents the impurities from flowing back.

[0014] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Example 1 Please see Figures 1-5 This utility model provides a technical solution: a high-efficiency ozone dissolved gas device, including a tank 1, a water inlet pipe 2 installed on the top surface of the tank 1, a drain outlet 4 for draining water opened at the bottom end of the tank 1, and a cavity 3 opened inside the tank 1, the cavity 3 connecting the water inlet pipe 2 and the drain outlet 4. Specifically, the dissolved ozone device generally consists of a tank 1, a cavity 3, a water inlet pipe 2, a drain outlet 4, an air inlet pipe, an air outlet pipe, a guide plate, a static mixer, and a diffuser. Wastewater first enters the cavity 3 from the tank 1 through the water inlet pipe 2 and flows under the guidance of the guide plate. At the same time, ozone gas is injected from the lower left side of the tank through the air inlet pipe. Under the action of the diffuser, it is dispersed into a large number of fine bubbles, forming a counter-current or cross-flow with the water flow, thereby significantly prolonging the gas-liquid contact time. When the water flows through the static mixer, the fluid is forced to stratify, shear, and remix, so that the ozone bubbles are fully broken and diffused in the water, increasing the mass transfer area and accelerating the ozone dissolution process. After being fully mixed, the ozone-rich water is discharged from the drain outlet 4, while the undissolved residual ozone gas naturally floats to the top of the tank due to density differences, is discharged through the air outlet pipe, and introduced into the exhaust gas treatment system.

[0016] Example 2 Based on Example 1, to prevent impurities in the wastewater from entering the tank 1 and affecting the ozone dissolution efficiency, a filter disc 5 is fixed inside the inlet pipe 2. The filter disc 5 is inclined and made of rigid material. A drain pipe 6 and a guide pipe 11 are installed around the outer ring of the inlet pipe 2. The drain pipe 6 is located directly above the guide pipe 11 and is inclined, with the inclination angle of the drain pipe 6 being the same as that of the filter disc 5. The lowest point of the drain pipe 6 is flush with the lowest point of the filter disc 5. The drain pipe 6 is connected to a connecting pipe 7 via a flange, and a collection tank 8 is screwed to the end of the connecting pipe 7. Used to collect impurities discharged from connecting pipe 7, connecting pipe 7 has an obtuse "L" shaped structure. A sewage discharge structure is installed inside connecting pipe 7, which includes overflow pipe 9, drain plate 12 and filter screen 13. Overflow pipe 9 is fixed to the outside of connecting pipe 7. A mounting cap 10 is fixed to the tail end of overflow pipe 9. The mounting cap 10 is sleeved on the outside of drainage pipe 11. The mounting cap 10 is made of tough material. Drain plate 12 is fixed to the inner wall of connecting pipe 7. Drain plate 12 is inclined and semi-enclosed. The communication port between overflow pipe 9 and connecting pipe 7 is located on the left side of drain plate 12. Filter screen 13 is fixed inside overflow pipe 9. Specifically, when sewage flows into the inlet pipe 2, small impurities that are not treated in time will be intercepted by the filter disc 5. Because the filter disc 5 is inclined and made of rigid material, the continuous flushing of water causes the impurities to slide along the inclined surface to the lowest point, and then enter the drain pipe 6. It then flows along the drain pipe 6 through the flange-connected connecting pipe 7 to the collection tank 8. Inside the connecting pipe 7, the drain plate 12, the overflow pipe 9, and the filter screen 13 of the sewage discharge structure work together. The drain plate 12 is semi-enclosed and inclined to guide the impurities into layers. The overflow pipe 9 is fixed to the outside of the connecting pipe 7 and passes through the filter screen 13. The cap 10 is fitted onto the outside of the drain pipe 11 so that when impurities flow into the connecting pipe 7 along with some sewage, the water level rises to a certain height, and the sewage can flow from the overflow pipe 9 into the drain pipe 11 and back into the inlet pipe 2. The filter screen 13 prevents impurities from flowing back with the water, thereby achieving continuous removal of impurities and circulation of sewage, ensuring that the ozone dissolution efficiency in the tank 1 is not affected by impurities. The baffle plate 12 prevents impurities from floating on the water surface when sewage rises. The semi-enclosed inclined baffle plate 12 prevents impurities from flowing out and restricts their position.

[0017] To reiterate, the filter disc 5 is made of a rigid material, which can maintain a stable shape during sewage flushing and is not easily deformed or damaged, thus effectively intercepting and holding small impurities; the mounting cap 10 is made of a tough material, which has good elasticity and flexibility, and is effectively connected to the drain pipe 11 to prevent it from falling off.

[0018] In operation, when wastewater enters the device through the inlet pipe 2, small impurities that are not treated in time are intercepted by the inclined filter disc 5 fixed inside the inlet pipe 2. Under the scouring of the water flow, these impurities slide continuously along the inclined surface until they reach the lowest point of the filter disc 5, and then enter the drain pipe 6. The wastewater then flows to the collection tank 8 through the connecting pipe 7, which is connected to the flange of the drain pipe 6. The wastewater discharge structure inside the connecting pipe 7 includes an inclined perforated plate 12 fixed to the inner wall of the pipe, an overflow pipe 9 on the outside, and a filter screen 13 inside, ensuring that the discharged impurities enter the collection tank with the water flow in the pipe. 8. Simultaneously, when the water level in the pipe rises, excess sewage flows out from the overflow pipe 9 and is guided back to the inlet pipe 2 through the installation cap 10 fitted on the drain pipe 11. This prevents floating impurities in the pipe from returning to the inlet pipe with the return water. At the same time, the filter screen 13 can intercept impurities, achieving effective separation and circulation discharge of impurities from the water flow, ensuring the cleanliness and efficiency of the water in the subsequent ozone dissolution process. When the inside of the connecting pipe 7 is blocked and cannot be used again, one end of the connecting pipe 7 is flanged, and the overflow pipe 9 on the outside of the connecting pipe 7 is fitted, making it easy to replace with a new one and continue to use it.
