Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular, to an ozone generating device for sewage treatment. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Ozone has strong oxidizing properties and preferentially attacks compounds containing double bonds and aromatic rings (such as dyes and drug residues), destroying complex molecular structures, and has no secondary pollution. After decomposition, it generates oxygen and has no chemical residues. It is mainly used in the treatment of refractory organic matter, disinfection and sterilization, decolorization and deodorization, and the removal of micro-pollutants, and has good treatment effects in industrial wastewater fields such as pharmaceuticals, printing and dyeing, and petrochemicals, the disinfection and sterilization of hospital sewage, and the residues of pesticides, etc.

[0003] There are also many methods for generating ozone, such as the electrolysis method, the dielectric barrier discharge method, and the ultraviolet irradiation method. Currently, most of the ozone generating devices for sewage treatment use the electrolysis method. Most of the power supply for traditional domestic high-power ozone generators adopts the power frequency boosting scheme or hard switching technology. The power switch tube has a low frequency, large loss, large occupied space, high noise, and poor anti-interference ability to the outside world. Especially when adjusting the ozone concentration, it is necessary to frequently adjust the power switch, with low adjustment efficiency and slow switch response, which affects the fine treatment effect of sewage. At the same time, currently ozone enters the interior of the sewage at a fixed position, and the ozone concentration in each part of the sewage, or rather the contact situation between the sewage and ozone in each part, is different, which is not convenient for comprehensively and effectively treating the sewage. Summary of the Invention

[0004] The present invention provides an ozone generating device for sewage treatment, which solves the problems in the prior art that the response of ozone concentration adjustment is slow and it is difficult to achieve uniform and fine treatment of each part of the sewage.

[0013] A stirring pipe that is communicated with the rotating pipe. The stirring pipe is communicated with an air release port through a one-way valve, and the air outlet direction of the air release port is the tangent direction of the rotation of the stirring pipe.

[0014] To ensure the stability of the movement of the air supply pipe, a limiting component is further included. The limiting component is used to make the air supply pipe move along a specific track. The limiting component includes:

[0015] A limiting rod that is fixedly connected to the sewage tank, and the driving pipe is in sliding fit with the limiting rod.

[0016] To improve the disinfection and sterilization effect on the sewage, the housing is arranged on the top of the sewage tank, and the housing is made of transparent quartz material.

[0017] To ensure the irradiation of the ultraviolet lamp on the sewage in the sewage tank, a partition board is fixedly connected inside the housing. The partition board divides the interior of the housing into a reaction chamber and a disinfection chamber. The partition board is made of transparent quartz material. The ultraviolet lamp and the partition board are located inside the reaction chamber. The air inlet and the air outlet are both communicated with the reaction chamber, and the light-shielding board is in contact with the partition board.

[0018] To extend the time of air in the housing and ensure the ozone preparation effect, a plurality of partition boards are fixedly connected inside the housing. The partition boards are located inside the reaction chamber. Ventilation openings are formed on the partition boards, and the ventilation openings between adjacent two partition boards are arranged in a staggered manner.

[0019] To ensure the stability of the ultraviolet lamp, a mounting seat electrically connected to the ultraviolet lamp is installed at one end of the housing, and a stabilizing component for limiting the ultraviolet lamp is arranged at the other end of the housing. The stabilizing component includes:

[0020] A skateboard, which is slidably connected to one end of the housing away from the mounting base;

[0021] A pressing plate, which is connected to the skateboard through a pressing spring and a telescopic rod, and the pressing plate contacts the end of the ultraviolet lamp.

[0022] To reduce gas leakage, an installation opening for the ultraviolet lamp to pass through is provided on the housing, and a sealing ring is fixedly connected inside the installation opening, and the sealing ring contacts the outer wall of the ultraviolet lamp.

[0028] 3. In the present invention, the ultraviolet lamp emits ultraviolet rays to the sewage in the sewage tank to assist in disinfection and sterilization above the sewage tank, reducing the impact of bacteria in the sewage on the surrounding environment. At the same time, the partition plate prevents air from entering the interior of the disinfection chamber, while controlling the ozone concentration, avoiding affecting the ultraviolet irradiation of the sewage;

[0029] 4. In the present invention, ozone enters the interior of the drive tube through the air supply pipe and is sent into the interior of the sewage through the exhaust port to purify and pneumatically stir the sewage. At the same time, the reaction force of the sewage against the discharged ozone pushes the air supply pipe to move along the limit rod. The connection between the drive tube and the air supply pipe is controlled by a valve, thereby controlling the moving direction of the air supply pipe, expanding the transmission range of ozone. Meanwhile, ozone enters the interior of the stirring tube through the rotating tube and is discharged through the air release port.

[0043] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0044] As Figures 1 to 6 As shown, this embodiment proposes an ozone generation device for sewage treatment, which is applied to the ozone supply in sewage treatment. It includes a housing 1, an air inlet 2 for air to enter and an air outlet 3 for ozone to discharge are connected to the housing 1. A gas mass flow controller 4 is installed at the air inlet 2. It also includes an ultraviolet lamp 5, a light shielding plate 6, an air delivery pipe 7, a driving component and a stirring component. The present invention emits 185nm ultraviolet rays through the ultraviolet lamp 5 to irradiate the oxygen or pure oxygen entering the housing 1 to generate ozone. The ozone enters the interior of the sewage through the air delivery pipe 7 to purify the sewage. The precision lead screw 201 drives the light shielding plate 6 to move precisely to finely adjust the irradiation area of the ultraviolet rays. At the same time, the gas mass flow controller 4 controls the air flow entering to control the concentration of ozone. The ultraviolet lamp 5 emits ultraviolet rays to the sewage in the sewage tank to assist in disinfection and sterilization above the sewage tank, reducing the impact of bacteria in the sewage on the surrounding environment. The ozone enters the interior of the driving pipe 301 through the air delivery pipe 7 and is sent into the sewage through the exhaust port 303. The reaction force of the sewage on the ozone discharge pushes the air delivery pipe 7 to move along the limit rod 304 to expand the ozone delivery range. At the same time, the ozone enters the interior of the stirring tube 402 through the rotating tube 401 and is discharged through the air vent 403. The reaction force of the sewage on the ozone discharge pushes the stirring tube 402 and the rotating tube to rotate. The stirring tube 402 mechanically stirs the sewage, and at the same time the ozone pneumatically stirs the sewage to expand the contact area between the sewage and the ozone and improve the uniformity of the ozone, thereby ensuring the purification effect of the sewage.

[0045] The ultraviolet lamp 5 is installed inside the housing 1. To ensure the stability of the ultraviolet lamp 5, a mounting base 8 electrically connected to the ultraviolet lamp 5 is installed at one end of the housing 1, and a stabilizing component for limiting the ultraviolet lamp 5 is provided at the other end of the housing 1. The stabilizing component includes a sliding plate 101 and a pressing plate 102. The sliding plate 101 is slidably connected to the end of the housing 1 away from the mounting base 8. The pressing plate 102 is connected to the sliding plate 101 through a pressing spring 103 and a telescopic rod. The pressing plate 102 contacts the end of the ultraviolet lamp 5. To reduce gas leakage, an installation opening for the ultraviolet lamp 5 to pass through is provided on the housing 1, and a sealing ring 9 is fixedly connected inside the installation opening. The sealing ring 9 contacts the outer wall of the ultraviolet lamp 5. One end of the ultraviolet lamp 5 is provided with a metal connector. One end of the metal connector passes through the two installation openings and extends into the interior of the mounting base 8. A metal connection base electrically connected to the metal connector is provided inside the mounting base 8. The ultraviolet lamp 5 is electrically connected to an external power supply device through the metal connection base. After the ultraviolet lamp 5 is installed, the sealing performance at the installation opening is ensured by the sealing ring 9 to prevent the gas inside the housing 1 from escaping. At the same time, the sliding plate 101 is slid, and under the action of the pressing spring 103, the pressing plate 102 limits the end of the ultraviolet lamp 5 to ensure the stability of the ultraviolet lamp 5. The ultraviolet lamp 5 emits 185nm ultraviolet light. The 185nm vacuum ultraviolet light can break the chemical bond of O2 in the air, making O2 become single atomic oxygen and undergo a photochemical reaction:

[0046] O2 + hν(<200nm) → 2O

[0047] O + O2(hν) → O3

[0048] O3 + 253.7nm → O2 + O

[0049] In the photochemical reaction, VUV has a strong ability to generate ozone. Ozone has a very strong oxidizing property. It can decompose harmful substances and play a role in disinfection and deodorization. Ozone absorbs 253.7nm ultraviolet light and generates O2 again. The stronger the intensity of the 253.7nm ultraviolet light, the easier it is for ozone to be consumed. The oxygen entering the housing 1 is irradiated by the ultraviolet light emitted by the ultraviolet lamp 5 to generate ozone, and the ozone is sent into the interior of the sewage through the air outlet 3 to purify the sewage.

[0050] The shading plate 6 is movably arranged inside the shell 1, and the shading plate 6 and the shell 1 are in a sealed sliding fit. The shading plate 6 is used to adjust the irradiation area of ​​the ultraviolet lamp 5. In order to realize the movement of the shading plate 6, an adjustment component is also included. The adjustment component is used to move the shading plate 6. The adjustment component includes a precision screw 201, and the precision screw 201 is rotatably arranged on the shell 1. A motor 202 is installed on the shell 1. The precision screw 201 is fixedly connected to the output end of the motor 202. The shading plate 6 is fixedly connected with a screw nut 203 matching the precision screw 201. The precision screw 201 can be driven to rotate by the motor 202, thereby driving the The rod nut 203 and the sunshade 6 move precisely. The sunshade 6 is made of opaque material and can block ultraviolet rays. As the sunshade 6 moves, the irradiation area of ​​ultraviolet rays is adjusted, thereby adjusting the concentration of ozone. At the same time, by cooperating with the gas mass flow controller 4 installed at the air inlet 2, the amount of oxygen entering the shell 1 is also adjusted, which can achieve precise adjustment of the ozone concentration to meet different requirements for sewage treatment. A support frame 204 is fixedly connected to the shell 1, and the precision screw rod 201 and the support frame 204 are rotatably connected, which can ensure the stability of the precision screw rod 201, thereby ensuring the stability of the movement of the sunshade 6.

[0051] The air supply pipe 7 is connected to the air outlet 3 and is used to transport ozone to the interior of the sewage pool. The driving component pushes the air supply pipe 7 to move under the reaction force of the ozone discharge. The driving component includes a driving pipe 301, which is connected to the air supply pipe 7. A valve 302 is installed on the driving pipe 301. The driving pipe 301 is provided with two groups. The two groups of driving pipes 301 are symmetrically arranged relative to the air supply pipe 7 along the moving direction of the air supply pipe 7. The driving pipe 301 is connected to the exhaust port 303 through a one-way valve. The exhaust direction of the exhaust port 303 coincides with the moving direction of the air supply pipe 7. In order to ensure the stability of the movement of the air supply pipe 7, a limit assembly is also included. The limit assembly is used to move the air supply pipe 7 along a specific trajectory. The limit assembly includes a limit rod 304, which is fixedly connected to the sewage pool. The driving pipe 301 and the limit rod 304 are in sliding fit, and the shell Ozone generated by the reaction in the body 1 enters the interior of the air supply pipe 7 through the air outlet 3, and is then discharged into the interior of the sewage through the driving pipe 301 and the exhaust port 303. The driving pipe 301 is located inside the sewage. The reaction force between the gas discharged through the exhaust port 303 and the sewage pushes the air supply pipe 7 to move in the opposite direction of the exhaust. By controlling the opening and closing of the two valves 302, the outlet direction of the exhaust port 303 can be controlled, thereby controlling the moving direction of the air supply pipe 7. The air supply pipe 7 is limited by the limiting rod 304, so that the air supply pipe 7 moves along the limiting rod 304 to ensure the stability of the air supply pipe 7. Through the movement of the air supply pipe 7, ozone is distributed to the entire sewage pool as much as possible, thereby improving the comprehensiveness and uniformity of sewage treatment. The one-way discharge of ozone is achieved by the one-way valve to prevent sewage from entering the interior of the air supply pipe 7 through the exhaust port 303.

[0052] The stirring assembly stirs the sewage under the reaction force of the discharged ozone. The stirring assembly includes a rotating pipe 401 and a stirring pipe 402. The rotating pipe 401 is rotationally connected to the air supply pipe 7 in a communicating manner. The stirring pipe 402 is connected to the rotating pipe 401. The stirring pipe 402 is connected to an air outlet 403 through a one-way valve. The air outlet direction of the air outlet 403 is the tangent direction of the rotation of the stirring pipe 402. Part of the ozone enters the inside of the rotating pipe 401 through the air supply pipe 7. The stirring pipe 402 is horizontally arranged. The ozone is discharged into the sewage through the stirring pipe 402 and the air outlet 403. Under the reaction force of the sewage on the discharged ozone, the stirring pipe 402 is pushed to rotate. The rotation of the stirring pipe 402 mechanically stirs the sewage. At the same time, the ozone enters the sewage to form bubbles to pneumatically stir the sewage, improving the contact between the ozone and the sewage, thereby further improving the purification efficiency and purification effect of the sewage. By the ozone entering the sewage, the moving range of the ozone is increased and the contact effect with the sewage is enhanced, having a synergistic effect.

[0053] To improve the disinfection and sterilization effect on the sewage, the housing 1 is arranged on the top of the sewage tank. The housing 1 can be installed above the sewage tank through a mounting frame or other supporting structures, so that the ultraviolet lamp 5 can irradiate the sewage tank. The housing 1 is made of transparent quartz material. In addition, the sewage tank in the attached drawing is a schematic diagram, not the actual size, and is drawn for the convenience of understanding this embodiment. To ensure the irradiation of the ultraviolet lamp 5 on the sewage in the sewage tank, a partition plate 10 is fixedly connected inside the housing 1. The partition plate 10 divides the inside of the housing 1 into a reaction chamber and a disinfection chamber. The partition plate 10 is made of transparent quartz material. Both the housing 1 and the partition plate 10 can be made of high-purity quartz, making the ozone gas highly pure, and no metal oxides and nitrogen oxides are generated, and there is no electromagnetic radiation interference. The ultraviolet lamp 5 and the partition plate 10 are located inside the reaction chamber. The air inlet 2 and the air outlet 3 are both communicated with the reaction chamber. The light-shielding plate 6 contacts the partition plate 10. The partition plate 10 is in the middle position of the housing 1. The lower side of the housing 1, that is, the side facing the sewage tank, is the disinfection chamber. The upper side of the housing 1 and the side communicated with the air inlet 2 and the air outlet 3 is the reaction chamber. Oxygen enters the inside of the reaction chamber, and ozone is generated by reacting the oxygen above through the ultraviolet lamp 5. By moving and blocking the upper side of the ultraviolet lamp 5 through the light-shielding plate 6, the irradiation amount is controlled. The lower side of the ultraviolet lamp 5 is always in the on state to continuously disinfect and sterilize the sewage tank. At the same time, the presence of the partition plate 10 prevents the oxygen and ozone on the upper side of the housing 1 from entering the lower side, thereby ensuring the irradiation adjustment effect of the light-shielding plate 6 on the ultraviolet lamp 5. Oxygen enters the lower side. Since the lower side of the ultraviolet lamp 5 is always in the irradiation state to disinfect and sterilize the sewage tank, it is not convenient to control the ozone concentration. Therefore, the upper side and the lower side of the ultraviolet are separated for different divisions of labor.

[0054] To extend the residence time of air inside the housing 1 and ensure the ozone production effect, a plurality of partitions 11 are fixedly connected inside the housing 1. The partitions 11 are located inside the reaction chamber, and ventilation openings are formed on the partitions 11. The ventilation openings between two adjacent partitions 11 are arranged staggeredly. Oxygen enters the inside of the housing 1 through the air inlet 2 and is guided by the plurality of partitions 11, extending the residence time of oxygen in the reaction chamber, thereby ensuring sufficient contact between oxygen and ultraviolet light and ensuring the ozone production effect.

[0055] It should be noted that the air pressure is regulated by an air compressor and a pressure reducing valve. The air is shunted by a needle valve and part of the shunted air is humidified by a water vapor volatilization tank. Then, the humidified air is mixed with the other part of the dry air to adjust the air humidity. The humidity of the mixed gas is monitored by a humidity probe and coordinated with the regulation of the needle valve to achieve the regulation of the gas humidity. Then, the gas after pressure regulation and humidity adjustment enters the inside of the housing 1 for reaction, and the ozone concentration is finely adjusted by controlling the ultraviolet irradiation amount through the gas mass flow controller 4 and the light shielding plate 6.

[0056] The working principle or usage process of this ozone generation device for sewage treatment is as follows:

[0057] Connect the gas source of the ozone generator. The air outlet of the air compressor is depressurized to 0.4 MPa by a pressure reducing valve, and after preliminary filtration and drying, it is connected to the equipment air inlet 2 using a 3 mm polytetrafluoroethylene tube. The pressure reducing valve of the equipment is adjusted to reduce the pressure to 0.2 MPa. The gas source is secondarily dried inside the equipment to reduce the air humidity to 0%RH. The gas mass flow controller 4 is adjusted to the required flow rate. The air is divided into two paths by a needle valve, one path enters the water vapor volatilization tank, and the other path enters the mixing pipe. The humid air coming out of the water vapor volatilization tank enters the mixing pipe and mixes with the dry air. By adjusting the needle valve, the purpose of adjusting the humidity is achieved. The humidity probe automatically monitors and measures the humidity of the gas at the outlet of the mixing pipe online. The gas coming out of the mixing pipe enters the inside of the housing 1 through the air inlet 2. The gas passes through the ventilation openings on the plurality of partitions 11 in sequence and passes through the reaction chamber. The oxygen in the gas or pure oxygen source generates ozone after being irradiated by 185 nm ultraviolet light;

[0058] Ozone enters the inside of the air delivery pipe 7 through the air outlet 3. Part of the ozone is discharged through the driving pipe 301 and the discharge port, pushing the air delivery pipe 7 to move along the limiting rod 304. Part of the ozone is discharged through the stirring pipe 402 and the air release port 403, pushing the stirring pipe 402 to rotate. While mechanically stirring the sewage, the ozone performs pneumatic stirring on the sewage, fully purifying the sewage. At the same time, the ultraviolet lamp 5 irradiates the upper part of the sewage, thereby achieving the effect of auxiliary disinfection and sterilization;

[0059] When the ozone concentration needs to be adjusted, the gas mass flow controller 4 is used to adjust the amount of gas entering the housing 1. At the same time, the motor 202 drives the precision lead screw 201 to rotate, adjusting the position of the light-shielding plate 6, that is, adjusting the irradiation area of the ultraviolet lamp 5 on oxygen, so as to control the concentration of ozone preparation and meet different requirements for sewage treatment.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
