[0002] Sewage treatment is the process of purifying sewage to make it meet the water quality requirements for discharge into a certain water body or reuse. 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 without secondary pollution. It produces oxygen after decomposition and has no chemical residues. It is mainly used for the treatment of difficult-to-degrade organic matter, disinfection and sterilization, decolorization and deodorization, and removal of micro-pollutants. It has good treatment effects in industrial wastewater fields such as pharmaceuticals, printing and dyeing, and petrochemicals, disinfection and sterilization of hospital sewage, and pesticide residues.

[0003] There are many ways to produce ozone, such as electrolysis, dielectric barrier discharge and ultraviolet irradiation. Currently, ozone generating equipment for sewage treatment mostly adopts electrolysis.

[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 6As shown, this embodiment proposes an ozone generating device for sewage treatment, which is applied to ozone supply in sewage treatment, including a shell 1, an air inlet 2 for air entry and an air outlet 3 for ozone discharge are connected on the shell 1, a gas mass flow controller 4 is installed at the air inlet 2, and also includes an ultraviolet lamp 5, a shading plate 6, an air supply pipe 7, a driving component and an agitating component. The present invention emits 185nm ultraviolet rays through the ultraviolet lamp 5 to irradiate the oxygen or pure oxygen entering the shell 1 to generate ozone, and the ozone enters the sewage through the air supply pipe 7 to purify the sewage, and the shading plate 6 is driven by the precision screw 201 to move accurately, and the irradiation area of ​​the ultraviolet rays is finely adjusted. At the same time, the incoming air flow is controlled by the gas mass flow controller 4, so as to adjust the concentration of the ozone. Control, ultraviolet rays are emitted to the sewage in the sewage pool through the ultraviolet lamp 5, and auxiliary disinfection and sterilization are performed above the sewage pool to reduce the impact of bacteria in the sewage on the surrounding environment. Ozone enters the interior of the driving tube 301 through the air supply pipe 7 and is sent into the interior of the sewage through the exhaust port 303. The reaction force of the sewage on the discharge of ozone pushes the air supply pipe 7 to move along the limit rod 304, thereby expanding the transmission range of ozone. At the same time, ozone enters the interior of the stirring tube 402 through the rotating tube 401 and is discharged through the vent 403. The reaction force of the sewage on the discharge of ozone 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, thereby expanding the contact area between the sewage and ozone and improving the uniformity of the ozone, thereby ensuring the purification effect of the sewage.

[0022] The ultraviolet lamp 5 is installed inside the shell 1. To ensure the stability of the ultraviolet lamp 5, a mounting seat 8 electrically connected to the ultraviolet lamp 5 is installed at one end of the shell 1. A stabilizing component for limiting the ultraviolet lamp 5 is provided at the other end of the shell 1. The stabilizing component includes a slide plate 101 and a clamping plate 102. The slide plate 101 is slidably connected to the end of the shell 1 away from the mounting seat 8. The clamping plate 102 is connected to the slide plate 101 through a clamping spring 103 and a telescopic rod. The clamping plate 102 is in contact with the end of the ultraviolet lamp 5. To reduce gas leakage, a mounting port for the ultraviolet lamp 5 to pass through is opened on the shell 1. A sealing ring 9 is fixedly connected to the inside of the mounting port. The sealing ring 9 and the ultraviolet lamp 5 The outer wall of the housing 1 is in contact with the ultraviolet lamp 5. One end of the ultraviolet lamp 5 is provided with a metal joint, and one end of the metal joint is extended into the interior of the mounting seat 8 through the two mounting openings. The interior of the mounting seat 8 is provided with a metal connecting seat electrically connected to the metal joint. The ultraviolet lamp 5 is electrically connected to the external power supply equipment through the metal connecting seat. After the ultraviolet lamp 5 is installed, the sealing of the mounting opening is ensured by the sealing ring 9 to prevent the gas in the housing 1 from escaping. At the same time, the sliding slide 101 is used to limit the end of the ultraviolet lamp 5 under the action of the pressing spring 103 to ensure the stability of the ultraviolet lamp 5. The ultraviolet lamp 5 emits 185nm ultraviolet rays. The vacuum ultraviolet rays of 185nm can convert O in the air into 2 The chemical bonds are broken, making O 2 Becomes monatomic oxygen and undergoes photochemical reaction: O 2 +hν(<200nm)→2O O+O 2 (hν)→O 3 O 3 +253.7nm→O 2 +O In the photochemical reaction, VUV has a strong ability to produce 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 rays and generates O 2 The stronger the 253.7nm ultraviolet intensity is, the easier it is for ozone to be consumed. The ultraviolet rays emitted by the ultraviolet lamp 5 irradiate the oxygen entering the shell 1 to produce ozone, and the ozone is sent into the sewage through the outlet 3 to purify the sewage.

[0023] 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.

[0024] 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.

[0025] The stirring assembly stirs the sewage under the reaction force of the ozone discharge, and the stirring assembly includes a rotating pipe 401 and a stirring pipe 402. The rotating pipe 401 is connected to the air supply pipe 7 by rotation, and the stirring pipe 402 is connected to the rotating pipe 401. The stirring pipe 402 is connected to the air outlet 403 through a one-way valve. The air outlet direction of the air outlet 403 is the tangential direction of the rotation of the stirring pipe 402. Part of the ozone enters the interior of the rotating pipe 401 through the air supply pipe 7. The stirring pipe 402 is horizontally arranged. The ozone passes through the stirring pipe 4 02 and the air outlet 403 are discharged into the interior of the sewage. Under the reaction force of the sewage on the discharged ozone, the stirring tube 402 is pushed to rotate. The stirring tube 402 rotates to mechanically stir the sewage. At the same time, ozone enters the sewage to form bubbles to pneumatically stir the sewage, thereby improving the contact between ozone and sewage, thereby further improving the purification efficiency and purification effect of the sewage. By allowing ozone to enter the sewage, the movement range of ozone is increased and the contact effect between ozone and sewage is enhanced, which has a synergistic effect.

[0026] In order to improve the disinfection and sterilization effect of sewage, the shell 1 is arranged on the top of the sewage pool. The shell 1 can be installed above the sewage pool through a mounting frame or other supporting structure, so that the ultraviolet lamp 5 can irradiate the sewage pool. The shell 1 is made of transparent quartz. In addition, the sewage pool in the accompanying drawings is a schematic diagram, not an actual size. It is drawn for the convenience of understanding this embodiment. In order to ensure that the ultraviolet lamp 5 irradiates the sewage in the sewage pool, an isolation plate 10 is fixedly connected to the inside of the shell 1. The isolation plate 10 divides the inside of the shell 1 into a reaction chamber and a disinfection chamber. The isolation plate 10 is made of transparent quartz. The shell 1 and the isolation plate 10 can be made of high-purity quartz, so that the ozone gas is highly pure, and no metal oxides and nitrogen oxides are generated, and there is no electromagnetic radiation interference. The ultraviolet lamp 5 and the isolation plate 10 are located inside the reaction chamber, and the air inlet 2 and the air outlet 3 are both connected to the reaction chamber. The shading plate 6 and the isolation plate The isolation plate 10 is in contact with the isolation plate 10, and the isolation plate 10 is in the middle position of the shell body 1. The lower part of the shell body 1, that is, the side facing the sewage pool, is a disinfection chamber. The upper part of the shell body 1 connected with the air inlet 2 and the air outlet 3 is a reaction chamber. Oxygen enters the interior of the reaction chamber, and the ultraviolet lamp 5 reacts with the oxygen above to generate ozone. The upper side of the ultraviolet lamp 5 is moved and shielded by the shading plate 6 to control the irradiation amount. The lower side of the ultraviolet lamp 5 is always in an on state to continuously disinfect and sterilize the sewage pool. At the same time, the existence of the isolation plate 10 prevents the oxygen and ozone on the upper side of the shell body 1 from entering the lower side, thereby ensuring the irradiation adjustment effect of the shading plate 6 on the ultraviolet lamp 5. Oxygen enters the lower side. Since the lower side of the ultraviolet lamp 5 is always in an irradiation state to disinfect the sewage pool, it is not convenient to control the ozone concentration. Therefore, the upper and lower sides of the ultraviolet lamp are separated for different divisions of labor.

[0027] In order to prolong the time that air stays in the shell 1 and ensure the ozone preparation effect, a plurality of partitions 11 are fixedly connected to the inside of the shell 1. The partitions 11 are located inside the reaction chamber. Vents are opened on the partitions 11. The vents between two adjacent partitions 11 are staggered. Oxygen enters the inside of the shell 1 through the air inlet 2 and is guided under the action of the plurality of partitions 11 to prolong the time that oxygen stays in the reaction chamber, thereby ensuring sufficient contact between oxygen and ultraviolet rays and ensuring the ozone preparation effect.

[0028] It should be noted that the air pressure is regulated by an air compressor and a pressure reducing valve, the air is diverted by a needle valve, and part of the diverted air is humidified by a water vapor volatilizer, and then the humidified air is mixed with another part of dry air to adjust the air humidity, and the humidity of the mixed gas is monitored by a humidity probe, and the humidity of the gas is regulated in coordination with the regulation of the needle valve, and then the pressure- and humidity-regulated gas enters the interior of the shell 1 for reaction, and the ultraviolet radiation is controlled by the gas mass flow controller 4 and the sunshade 6 to achieve fine regulation of the ozone concentration.

[0029] The working principle or use process of the ozone generator for sewage treatment is: The ozone generator gas source is connected, and the air compressor outlet gas is reduced to 0.4MPa through the pressure reducing valve. After preliminary filtration and drying, a 3mm polytetrafluoroethylene tube is used to connect to the equipment air inlet 2. The equipment pressure reducing valve is adjusted to reduce the pressure to 0.2MPa. The air source is dried twice in 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 using a needle valve, one path enters the water vapor volatilizer, and the other path enters the mixing pipe. The wet air from the water vapor volatilizer enters the mixing pipe and mixes with the dry air. The purpose of adjusting the humidity is achieved by adjusting the needle valve. The humidity probe automatically monitors and measures the gas humidity at the outlet of the mixing pipe online. The outlet gas of the mixing pipe enters the interior of the shell 1 through the air inlet 2. The gas passes through the reaction chamber through the vents on the multiple partitions 11 in turn. The oxygen or pure oxygen source in the gas is irradiated with 185nm ultraviolet rays to produce ozone. Ozone enters the interior of the air supply pipe 7 through the air outlet 3, and part of the ozone is discharged through the driving pipe 301 and the discharge port, pushing the air supply pipe 7 to move along the limit rod 304, and part of the ozone is discharged through the stirring pipe 402 and the air outlet 403, pushing the stirring pipe 402 to rotate, while the sewage is mechanically stirred, the ozone pneumatically stirs the sewage, and the sewage is fully purified. At the same time, the ultraviolet lamp 5 irradiates the upper part of the sewage, thereby achieving the effect of auxiliary disinfection and sterilization; When the ozone concentration needs to be adjusted, the amount of gas entering the shell 1 is adjusted by the gas mass flow controller 4. At the same time, the motor 202 drives the precision screw 201 to rotate and adjust the position of the shading plate 6, that is, the irradiation area of ​​the ultraviolet lamp 5 to oxygen is adjusted, thereby controlling the concentration of ozone preparation to meet different needs for sewage treatment.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
