Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment equipment, specifically relating to a vertical jet ozone dissolving device. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] In ozone oxidation processes in the water treatment field, jet aeration equipment is a core supporting device to ensure process efficiency. Its core performance revolves around the efficient integration of ozone into the water body. As a key link connecting the ozone source and the water to be treated, it can transform ozone gas into a form that is easily mixed with water through specific fluid dynamics design, greatly enhancing the gas-liquid contact effect. This helps ozone fully exert its role in degrading pollutants, inactivating microorganisms, and removing odors and color from the water, thereby supporting the water quality improvement needs of scenarios such as water supply treatment, deep purification of industrial wastewater, and circulating water maintenance.

[0004] Jet aeration equipment is widely used in ozone oxidation processes due to its high mass transfer efficiency. In engineering applications, it significantly improves the transfer and dissolution efficiency of ozone in water. However, jet aeration equipment has certain requirements for the reaction distance after the outlet. In the ozone treatment unit of water treatment plant, due to the small ozone dosage and short residence time, most ozone reactors are small in size and cannot meet the requirements of the optimal spray distance at the outlet. Therefore, when the size of the ozone reactor is limited, the outlet distance of the jet aerator is short. After the gas and liquid are sprayed from the outlet of the jet aerator, they encounter the tank wall obstacle, resulting in vertical rebound on the tank wall, bubble accumulation, and a sharp decrease in the transfer and dissolution efficiency of ozone. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A vertical jet ozone dissolving device includes a jet inlet pipe, a jet contraction pipe, a nozzle, an intake chamber, a tail pipe, a guide tube, and a conical disperser. The upper end of the jet inlet pipe is connected to the guide tube, the lower end of the jet inlet pipe is provided with the jet contraction pipe, the lower end of the jet contraction pipe is provided with the nozzle, the lower end of the nozzle is provided with the intake chamber, and the lower end of the intake chamber is provided with the tail pipe.

[0007] As a further technical solution, the jet inlet pipe, jet contraction pipe, nozzle, air intake chamber, tail pipe, guide tube, and conical disperser are coaxially arranged in the vertical direction.

[0008] As a further technical solution, the upper end of the jet inlet pipe extends out of the guide tube, and the jet inlet pipe and the guide tube are fixedly connected by support strips, with several support strips spaced apart; one end of the support strip is connected to the guide tube, and the other end of the support strip is connected to the side wall of the jet inlet pipe.

[0009] As a further technical solution, the upper end of the jet contraction tube is fixedly connected to the inner wall of the jet inlet tube, and the lower end of the jet contraction tube is fixedly connected to the nozzle.

[0010] As a further technical solution, the jet contraction tube is a tapered pipe, and the inlet opening of the jet contraction tube near the jet inlet pipe is greater than the outlet opening near the nozzle.

[0011] As a further technical solution, the diameter of the nozzle is the same as the outlet diameter of the jet contraction tube, and the diameter of the jet inlet tube is the same as the inlet diameter of the jet contraction tube; the outlet of the nozzle extends into the intake chamber.

[0012] As a further technical solution, the tailpipe is a tapered pipe, the opening of the inlet of the tailpipe near the air intake chamber is greater than the opening of the outlet; the length of the tailpipe is greater than the diameter of the jet inlet pipe; the outlet diameter of the tailpipe is smaller than the diameter of the jet inlet pipe; and the tailpipe has an angle with the air intake chamber. As a further technical solution, the guide tube is disposed on the outer periphery of the jet inlet pipe, and the diameter of the guide tube is larger than the diameter of the jet inlet pipe; the top and bottom of the guide tube are open, the bottom is flush with the end of the tail pipe, and the top is flush with the upper end of the jet contraction pipe.

[0013] As a further technical solution, the air intake pipe is a bent pipe, one end of which passes through the guide tube and communicates with the air intake chamber, and the other end of which is parallel to the jet inlet pipe.

[0014] As a further technical solution, the conical disperser has a conical structure, the diameter of the cone bottom of the conical disperser is larger than the diameter of the guide tube, and the distance from the end of the tail pipe to the cone top of the conical disperser is larger than the diameter of the jet inlet pipe; the guide tube and the conical disperser are fixedly connected by multiple fixed steel pipes evenly distributed in a circle, and one end of the fixed steel pipe passes through the conical disperser and is fixedly connected to the support plate.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are: This invention vertically and coaxially arranges and sequentially connects a jet inlet pipe, a jet contraction pipe, a nozzle, an intake chamber, a tailpipe, and a conical disperser. The water to be treated enters through the jet inlet pipe, is accelerated by the jet contraction pipe, sprayed through the nozzle, and then guided by the tailpipe, flowing vertically throughout. The jet contraction pipe is a tapered pipe; as the water flows through it, its velocity increases. After being sprayed through the nozzle into the intake chamber, it rapidly exits through the tailpipe. Due to the viscosity of the rapidly sprayed liquid, a negative pressure is created within the intake chamber. An air inlet pipe connected to the intake chamber introduces ozone gas, which is efficiently absorbed and initially mixed with the water using the negative pressure environment, ensuring a preliminary gas-liquid mixing effect. The tailpipe is a tapered pipe with a length greater than the diameter of the jet inlet pipe, an outlet diameter smaller than the inlet pipe diameter but larger than the nozzle diameter, and forms a specific angle with the intake chamber. When the vertically flowing gas-liquid mixture passes through the tailpipe, the pressure is further increased and maintained, the ozone solubility is improved, and the gas-liquid mixing is more thorough. At the same time, the gas-liquid mixture is sprayed from the tailpipe to the conical disperser below. The distance between the tailpipe and the conical disperser can be appropriately adjusted according to the spray velocity and the gas-liquid mixing ratio so that the gas-liquid mixture contacts the conical disperser with minimal resistance. This allows the vertical jet ozone dissolved gas device to be applied to ozone reactors of various sizes and environmental conditions, overcoming the problem of limited reaction distance at the jet outlet of conventional horizontally installed jet aerators, and broadening the application range of jet aerators.

[0016] At the same time, the conical disperser causes the water jet ejected from the jet outlet to continuously increase in size until it collides with the inclined surface of the disperser at a certain angle. Then, it gradually and evenly disperses along the inclined surface of the disperser to the area around the jet, further extending the reaction time and gradually starting to move upward. This can increase the ozone dissolution and utilization efficiency by 60-80%.

[0017] This invention features a guide tube around the ejector. The high-speed water flow at the ejector outlet, driven by viscosity, propels the water flow from top to bottom through the guide tube. Water containing ozone bubbles enters the guide tube from the top and flows rapidly downwards, moving together with the high-speed water flow at the ejector outlet to participate in the secondary dissolution reaction, thereby further improving the ozone dissolution efficiency.

Detailed Implementation

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] Jet aeration equipment is widely used in ozone oxidation processes due to its high mass transfer efficiency. In engineering applications, it significantly improves the transfer and dissolution efficiency of ozone in water. However, jet aeration equipment has certain requirements for the reaction distance after the outlet. In the ozone treatment unit of water treatment plant, due to the small ozone dosage and short residence time, most ozone reactors are small in size and cannot meet the requirements of the optimal spray distance at the outlet. Therefore, when the size of the ozone reactor is limited, the outlet distance of the jet aerator is short. After the gas and liquid are sprayed from the outlet of the jet aerator, they encounter the tank wall obstacle, resulting in vertical rebound on the tank wall, bubble accumulation, and a sharp decrease in the transfer and dissolution efficiency of ozone.

[0022] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a vertical jet ozone dissolving device, such as... Figure 1 and Figure 2 As shown, the system includes a jet inlet pipe 1, a jet contraction pipe 2, a nozzle 3, an intake chamber 4, a tailpipe 5, a guide tube 8, and a conical disperser 7. The upper end of the jet inlet pipe 1 is connected to the guide tube 8. The lower end of the jet inlet pipe 1 is provided with the jet contraction pipe 2, the lower end of the jet contraction pipe 2 is provided with the nozzle 3, the lower end of the nozzle 3 is provided with the intake chamber 4, and the lower end of the intake chamber 4 is provided with the tailpipe 5. The conical disperser 7 is provided below the outlet of the tailpipe 5, and the air inlet pipe 6 is provided on the side of the guide tube 8. The jet inlet pipe 1, the jet contraction pipe 2, the nozzle 3, the intake chamber 4, the tailpipe 5, the guide tube 8, and the conical disperser 7 are coaxially arranged in the vertical direction.

[0023] Specifically, the jet inlet pipe 1, jet contraction pipe 2, nozzle 3, intake chamber 4, and tail pipe 5 are sequentially and sealed together. A conical diffuser 7 is installed below the outlet of the tail pipe 5, and an air inlet pipe 6 is installed on the side of the intake chamber 4 and the guide tube 8.

[0024] By vertically and coaxially arranging and sequentially connecting the jet inlet pipe 1, jet contraction pipe 2, nozzle 3, air intake chamber 4, tail pipe 5, and conical disperser 7, the water to be treated enters through the jet inlet pipe 1, is accelerated by the jet contraction pipe 2, sprayed by the nozzle 3, and then guided by the tail pipe 5, flowing vertically throughout the entire process. The jet contraction pipe 2 is a gradually narrowing pipe, and the flow velocity of the water to be treated increases when it flows through the jet contraction pipe 2, forming a negative pressure in the air intake chamber 4. At the same time, the air inlet pipe 6 can introduce ozone gas into the air intake chamber 4, and utilize the negative pressure environment to efficiently absorb ozone and initially mix it with the water, without being affected by vertical gravity, ensuring the initial gas-liquid mixing effect.

[0025] The tailpipe 5 is a tapered pipe, with a length greater than the diameter of the jet inlet pipe 1 and an outlet diameter smaller than the diameter of the jet inlet pipe 1 but larger than the nozzle diameter, forming a specific angle with the intake chamber 4. When the vertically flowing gas-liquid mixture passes through the tailpipe 5, the pressure is further increased and maintained, resulting in more thorough gas-liquid mixing. Simultaneously, the gas-liquid mixture is sprayed through the tailpipe 5 onto the conical disperser 7 below. This enables ozone reactors to be applied to various sizes and environmental conditions, overcoming the limitation of reaction distance at the jet outlet in conventional horizontally installed jet aerators, and broadening the application range of jet aerators.

[0026] At the same time, the conical disperser 7 causes the water jet ejected from the jet outlet to continuously increase in size until it collides with the inclined surface of the disperser at a certain angle. Then, it gradually and evenly disperses along the inclined surface of the disperser to the area around the jet injector, further extending the reaction time and gradually starting to move upward, which can improve the efficiency of ozone dissolution and utilization.

[0027] A guide tube 8 is installed around the jet injector. The high-speed water flow at the jet outlet is driven by the viscosity force to flow water from top to bottom through the guide tube 8. Water containing ozone bubbles outside the guide tube 8 enters the guide tube 8 from the top and flows rapidly downwards. It moves together with the high-speed water flow at the jet outlet and participates in the secondary dissolution reaction, further improving the ozone dissolution efficiency.

[0028] The upper end of the jet inlet pipe 1 extends out of the guide tube 8. The jet inlet pipe 1 and the guide tube 8 are fixedly connected by support strips 11, and several support strips 11 are arranged at intervals. One end of the support strip 11 is connected to the guide tube 8, and the other end of the support strip 11 is connected to the side wall of the jet inlet pipe 1.

[0029] Specifically, in the assembly of the jet inlet pipe 1 and the guide tube 8, the upper end of the jet inlet pipe 1 extends upwards out of the top opening of the guide tube 8. To achieve a stable connection between the two, several support strips 11 are arranged at intervals along the outer periphery of the jet inlet pipe 1. One end of each support strip 11 is fixed to the inner wall of the guide tube 8, and the other end is fixed to the side wall of the jet inlet pipe 1. Through the synergistic effect of multiple support strips 11, the jet inlet pipe 1 maintains a stable coaxial position inside the guide tube 8, avoiding displacement caused by water flow impact.

[0030] More specifically, the length-to-diameter ratio of the jet inlet pipe 1 is 5-7:1.

[0031] The upper end of the jet contraction tube 2 is fixedly connected to the inner wall of the jet inlet tube 1, and the lower end of the jet contraction tube 2 is fixedly connected to the nozzle 3.

[0032] Specifically, the upper end of the jet contraction tube 2 is tightly fixed to the inner wall of the jet inlet tube 1, and the lower end of the jet contraction tube 2 is fixed to the upper end of the nozzle 3, so that the water flow accelerated by the jet contraction tube 2 can directly enter the nozzle 3, ensuring a smooth fluid flow path.

[0033] The jet contraction tube 2 is a tapered pipe, and the inlet opening of the jet contraction tube 2 near the jet inlet pipe 1 is greater than the outlet opening near the nozzle 3.

[0034] Specifically, the jet contraction tube 2 adopts a tapered structure design. The pipe opening at the end near the inlet of the jet inlet pipe 1 is larger. As it extends towards the nozzle 3, the pipe opening gradually decreases, eventually forming a smaller opening at the outlet end near the nozzle 3. This allows the water flow velocity to gradually increase as the pipe cross-section gradually shrinks during the process of flowing through the jet contraction tube 2.

[0035] The diameter of nozzle 3 is the same as the outlet diameter of jet contraction tube 2, and the diameter of jet inlet tube 1 is the same as the inlet diameter of jet contraction tube 2; the outlet of nozzle 3 extends into the air intake chamber 4.

[0036] Specifically, the size matching relationship between nozzle 3, jet contraction tube 2, and jet inlet tube 1 is determined so that the diameter of nozzle 3 is consistent with the diameter of the outlet of jet contraction tube 2, ensuring that the water flow does not generate turbulence due to a sudden change in diameter when entering nozzle 3 from jet contraction tube 2. At the same time, the diameter of jet inlet tube 1 is the same as the diameter of the inlet of jet contraction tube 2, ensuring that the water flow enters jet contraction tube 2 smoothly. Furthermore, the outlet end of nozzle 3 extends downward into the internal space of air intake chamber 4, so that the water flow sprayed from nozzle 3 can directly contact and mix with the ozone gas in air intake chamber 4.

[0037] More specifically, the outlet of nozzle 3 extends into the interior of the intake chamber 4, the length of the extension tube of nozzle 3 is 2-3:1 to the diameter of nozzle 3, the diameter of intake tube 6 is 0.7-0.9:1 to the diameter of nozzle 3, the center line of intake tube 6 is flush with the end of the extension tube of nozzle 3, and the length of intake chamber 4 is 2.5-3.5:1 to the diameter of intake chamber 4.

[0038] Tailpipe 5 is a tapered pipe. The opening of the inlet of tailpipe 5 near the intake chamber 4 is greater than the opening of the outlet. The length of tailpipe 5 is greater than the diameter of jet inlet pipe 1. The outlet diameter of tailpipe 5 is smaller than the diameter of jet inlet pipe 1. Tailpipe 5 and intake chamber 4 have an angle.

[0039] Specifically, the tailpipe 5 is designed as a tapered pipe. The inlet end of the pipe near the intake chamber 4 has a larger opening to facilitate the reception of the gas-liquid mixture from the intake chamber 4. As it extends towards the outlet, the pipe opening gradually decreases, resulting in a smaller opening at the outlet end. At the same time, the overall length of the tailpipe 5 is designed to be greater than the diameter of the jet inlet pipe 1, and the diameter of the tailpipe 5 outlet is smaller than the diameter of the jet inlet pipe 1. Furthermore, the connection between the tailpipe 5 and the intake chamber 4 forms a certain angle, which allows the gas-liquid mixture to be accelerated and guided downward in a specific direction when flowing in the tailpipe 5.

[0040] More specifically, the length of the tailpipe 5 is 5-7 times the diameter of the jet inlet pipe 1, the outlet diameter of the reduced tailpipe 5 is 0.6-0.8 times the diameter of the jet inlet pipe 1, and the angle β between the reduced tailpipe 5 and the intake chamber 9 is 165°-178°.

[0041] The guide tube 8 is set on the outer periphery of the jet inlet pipe 1, and the diameter of the guide tube 8 is larger than the diameter of the jet inlet pipe 1; the top and bottom of the guide tube 8 are open, the bottom is flush with the end of the tail pipe 5, and the top is flush with the upper end of the jet contraction pipe 2.

[0042] Specifically, the guide tube 8 is fitted around the outer periphery of the jet inlet pipe 1. The inner diameter of the guide tube 8 is designed to be larger than the outer diameter of the jet inlet pipe 1, forming an annular space between the two. The top and bottom of the guide tube 8 are both designed as open structures. The open end at the bottom is flush with the end of the tail pipe 5, and the open end at the top is flush with the upper end of the jet contraction pipe 2, so that the guide tube 8 can completely cover the key areas related to gas-liquid mixing in the jet inlet pipe 1.

[0043] More specifically, the diameter of the guide tube 8 is 6 to 8 times the diameter of the jet inlet pipe 1. The top and bottom of the guide tube 8 are open, the bottom is flush with the end of the tail pipe 5, and the top is flush with the beginning of the jet contraction pipe 2. The air inlet pipe 6, which is sealed and fixedly connected to the side wall of the air intake chamber 4, extends to the outside of the guide tube 8 and then bends at 90° to the inlet end of the jet inlet pipe 1, parallel to the jet inlet pipe 1.

[0044] The intake pipe 6 is a bent pipe. One end of the intake pipe 6 passes through the guide tube 8 and is connected to the jet inlet pipe 1. The other end of the intake pipe 6 is parallel to the jet inlet pipe 1.

[0045] Specifically, the intake pipe 6 adopts a bent pipe structure, with one end passing through the side wall of the guide tube 8 and connecting to the jet inlet pipe 1, ensuring that ozone gas can enter the interior of the jet inlet pipe 1 through the intake pipe 6. The other end of the intake pipe 6 is bent towards the inlet end of the jet inlet pipe 1, ultimately forming a state parallel to the jet inlet pipe 1, which facilitates connection with the external ozone source pipeline and avoids interference with other components of the equipment caused by the pipeline layout.

[0046] The conical disperser 7 has a conical structure. The diameter of the cone bottom of the conical disperser 7 is larger than the diameter of the guide tube 8. The distance from the end of the tail pipe 5 to the cone top of the conical disperser 7 is larger than the diameter of the jet inlet pipe 1. The guide tube 8 and the conical disperser 7 are fixedly connected by multiple fixed steel pipes 9 that are evenly distributed around the circumference. One end of the fixed steel pipe 9 passes through the conical disperser 7 and is fixedly connected to the foot plate 10.

[0047] Specifically, the conical disperser 7 is manufactured with a conical structure. The diameter of its cone bottom is designed to be larger than the diameter of the guide tube 8, ensuring that the gas-liquid mixture ejected from the tail pipe 5 can completely impact the inclined surface of the conical disperser 7. The distance from the end of the tail pipe 5 to the cone top of the conical disperser 7 is set to be larger than the diameter of the jet inlet pipe 1, providing sufficient spray space for the gas-liquid mixture. The guide tube 8 and the conical disperser 7 are fixed by multiple fixed steel pipes 9. The fixed steel pipes 9 are evenly distributed along the circumference. One end of each fixed steel pipe 9 is fixed to the outer wall of the guide tube 8, and the other end passes through the conical disperser 7 and is fixed to the foot plate 10, so that the conical disperser 7 and the guide tube 8 maintain a relatively fixed positional relationship.

[0048] More specifically, the conical diffuser 7 is located below the outlet of the tailpipe 5, with a cone angle of 120°-135°, a cone bottom diameter of 1.3 to 1.5 times that of the guide tube 8, and a distance from the end of the tailpipe 5 to the cone top of 20 to 30 times that of the jet inlet pipe 1.

[0049] The guide tube 8 and the conical disperser 7 are fixedly connected by multiple circumferentially distributed fixed steel pipes 9 to ensure the stability of the overall structure. After passing through the conical disperser 7, the fixed steel pipes 9 continue to extend for a distance and connect to a foot plate 10. The foot plate 10 can be square or round and is used to fix it to the bottom of the reactor.

[0050] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
