Description

Technical Field

[0001] This invention relates to the fields of water treatment and advanced oxidation technology, specifically to a reaction device that utilizes pressurized ozone atmosphere, liquid atomization to enhance gas-liquid mass transfer, and ultraviolet light synergistic oxidation to treat pollutants in water. Background Technology

[0002] Pharmaceutical wastewater, medical wastewater, industrial wastewater, and effluent from wastewater treatment plants may contain antibiotics, drug residues, endocrine disruptors, and other recalcitrant organic pollutants. These pollutants are characterized by low concentrations, complex structures, and poor biodegradability, and conventional biological treatment processes have limited removal capabilities.

[0003] Ozone has strong oxidizing properties and can directly oxidize some organic pollutants. Under ultraviolet light, it can generate even more reactive oxidizing species. However, traditional ozone treatment often involves introducing ozone bubbles into a continuous aqueous phase, which has problems such as limited gas-liquid contact area, high ozone mass transfer resistance, and a large amount of residual ozone in the exhaust gas. At the same time, ultraviolet light may cause uneven irradiation and insufficient effective optical path inside the reactor.

[0004] Therefore, it is necessary to provide a reaction device that enables the liquid to be treated to enter the ozone phase reaction zone in the form of micro-droplets, and to improve the ozone mass transfer and pollutant degradation efficiency through positive pressure ozone atmosphere, ultraviolet reflection structure and optional catalytic module. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art. This invention provides a pressurized atomized ozone ultraviolet reaction device and its usage method to increase the contact area between ozone and the liquid to be treated, improve ozone mass transfer efficiency and ultraviolet light utilization, and make the device structure adaptable to different processing scales and installation spaces.

[0006] The technical solution of the present invention: a pressurized atomized ozone ultraviolet reaction device, comprising: The reactor has a hollow interior forming a closed and pressure-resistant reaction chamber. The reaction chamber is bounded by the highest water level line. Above the highest water level line is the gas phase reaction zone, and below the highest water level line is the liquid collection zone. The reactor is provided with an inlet and an outlet corresponding to the liquid collection zone. The atomization module includes an atomizing tube, an atomizer, and a liquid pressurization and delivery assembly. The atomizing tube is located in the gas phase reaction zone or along the inner wall of the reactor. The atomizer is located on the atomizing tube and atomizes the liquid to be treated and sprays it toward the gas phase reaction zone. The atomizing tube is connected to the liquid collection zone or an external water tank through a circulation pipeline. The liquid pressurization and delivery assembly is provided on the circulation pipeline. An ozone generating module includes an ozone generator and an air intake control component. The ozone generator is located outside the reactor, and the reactor is provided with an air inlet. The ozone generator delivers ozone into the reaction chamber through the air inlet, and the air intake control component adjusts the ozone intake volume. An ultraviolet irradiation module includes an ultraviolet lamp strip, which is disposed in the gas phase reaction zone, and the inner wall of the reaction chamber is provided with an ultraviolet reflective surface; The pressure detection and regulation module includes a pressure gauge and an exhaust control component. The pressure gauge is mounted on the reactor and its end extends into the reaction chamber. The exhaust control component includes an exhaust port on the reactor, through which exhaust gas is discharged from the reaction chamber. An ozone detection module includes an ozone detector. The reactor is equipped with a detection port, and the ozone detector is connected to the gas phase reaction zone through the detection port to detect the gas phase ozone concentration.

[0007] Furthermore, the reactor has at least one mounting port on its side wall corresponding to the gas phase reaction zone. The mounting port communicates with the reaction chamber. A fan is installed in the mounting port to promote the circulation of ozone gas in the gas phase reaction zone. The fan is equipped with an ozone-resistant sealing and isolation structure.

[0008] Furthermore, the reaction chamber is also equipped with a suspended catalytic module for promoting ozone decomposition or photocatalytic reaction. The suspended catalytic module includes a catalytic support and catalytic material disposed on the catalytic support.

[0009] Further, the catalytic material is one or more of metal oxides, carbon-based catalytic materials, or photocatalytic materials.

[0010] Further, the ultraviolet reflective surface is at least one of a mirror stainless steel surface, an aluminum reflective layer, a silver reflective layer, or an ozone-resistant ultraviolet reflective film.

[0011] Further, the atomizer is at least one of a pressure atomizing nozzle, a gas-liquid two-phase atomizing nozzle, or an ultrasonic atomizer, and the median droplet size formed by the atomizer is 10–200 μm.

[0012] Further, the ultraviolet lamp strip is at least one of a low-pressure mercury lamp, a medium-pressure mercury lamp, or an ultraviolet LED lamp, with an ultraviolet wavelength of 185–365 nm and a power of 10–200 W for a single ultraviolet lamp; the ultraviolet lamp strip is disposed on the inner wall of the reaction chamber, and an ultraviolet-transmitting protective sleeve and an ozone-resistant sealing element are provided outside the ultraviolet lamp strip.

[0013] Furthermore, the reactor is made of stainless steel or plastic material with a pressure resistance rating.

[0014] Further configuration: the exhaust port is positioned above the highest water level line, and the exhaust port is connected to the ozone exhaust gas decomposition device via a pressure regulating valve.

[0015] Another technical solution, a method for treating water using a pressurized atomized ozone ultraviolet reaction device, includes the following steps: S1, Liquid inlet, close the outlet, introduce the liquid to be treated into the collection area through the inlet and make the liquid level lower than the highest water level line; S2, ozone input: Before the atomization process begins, the ozone generator and fan are started. Ozone is input into the reaction chamber through the ozone generator to replace the original gas in the reaction chamber, so that an ozone atmosphere is pre-formed in the gas phase reaction zone. S3, Ozone input pressurization, continuously input ozone into the reaction chamber to increase the pressure inside the reactor. By adjusting the ozone inlet flow rate and the exhaust flow rate of the outlet, the pressure inside the reactor is slowly increased to the set range of 0.01~0.30MPa. The pressure gauge continuously monitors the pressure in the reaction chamber, and the ozone detector continuously monitors the gas phase ozone concentration in the reaction chamber. S4, atomization and ultraviolet reaction: the liquid pressurization and delivery component and ultraviolet lamp bar are activated. The liquid to be treated in the collection area enters the atomization tube and is sprayed by the atomizer to form micro-droplets. The droplets come into contact with ozone, are irradiated by the ultraviolet lamp bar, and come into contact with the catalytic material in the gas phase reaction zone. S5, collection and circulation: the droplets after the reaction flow into the collection area under the action of gravity and can be circulated and atomized multiple times. S6, shutdown and discharge: After the set treatment time is reached or the water quality meets the standard, the ozone generator and liquid pressurization and delivery components are stopped, the fan continues to run, and the exhaust gas is sent to the ozone exhaust gas decomposition device through the exhaust port. After the pressure inside the reaction chamber reaches equilibrium with the outside and the ozone concentration reaches the safe condition, the treated liquid is discharged from the outlet and the fan is turned off. During the atomization process, ozone can be continuously introduced into the reaction chamber to replenish the ozone consumed by the reaction and maintain the set ozone concentration.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: (1) The continuous liquid phase is transformed into dispersed micro-droplets, which increases the gas-liquid interface area and shortens the mass transfer distance of ozone in the droplets; (2) Ozone can be pre-introduced or continuously introduced during the treatment process, which can maintain the ozone concentration in the gas phase reaction zone, and can also form a positive pressure through ozone input, thereby improving the ozone partial pressure, mass transfer driving force and ozone effective utilization rate, and facilitating centralized treatment of exhaust gas; (3) Expand the ultraviolet light coverage range by using ultraviolet reflective surfaces to improve the light energy utilization rate of ozone / ultraviolet synergistic oxidation; (4) Improve ozone distribution in the gas phase reaction zone through gas circulation components, and further enhance the reaction through optional suspended catalytic modules; (5) The reactor can be square, cylindrical or other shapes, without restriction. The treated liquid can be discharged in one pass or circulated and atomized, which is convenient for modular design according to the treatment scale. Attached Figure Description

Example

[0023] like Figure 1-7 As shown, reactor 1 has a square, sealed, pressure-resistant structure. Reactor 1 can be made of 304 stainless steel or 316L stainless steel, and the inner surface is mirror-polished. The inner wall of the reactor is provided with a reflective surface. When the reactor is made of stainless steel, the reflective surface is a mirror stainless steel surface, an aluminum reflective layer, and a silver reflective layer. Alternatively, it can be made of PP, PVDF, or other ozone-resistant engineering plastics with corresponding pressure resistance levels, and an ozone-resistant ultraviolet reflective film is provided on its inner surface to form a reflective surface. The external dimensions of reactor 1 can be determined according to the processing capacity. The square shape is not a limitation on the appearance of this invention.

[0024] The reactor 1 has a hollow interior forming a sealed, pressure-resistant reaction chamber. The reaction chamber is divided by the highest water level line 11. Below the highest water level line 11 is the collection zone 12. The side wall of the reactor 1 is provided with an inlet 14 and an outlet 15, which are connected to the collection zone 12. Above the highest water level line 11 is the gas phase reaction zone 13, which is equipped with an atomizing module 2, an ultraviolet irradiation module, and a fan 18. During operation, the liquid level in the collection zone 12 is controlled below the highest water level line 11, so that a continuous gas phase reaction zone 13 is maintained above the highest water level line 11. Inlet pipes and outlet pipes can be installed at the inlet 14 and outlet 15, respectively, and control valves are installed on the inlet pipes and outlet pipes. The outlet 15 is used to discharge the treated liquid and can also be connected to an external circulating water tank.

[0025] The atomization module 2 includes an atomizing tube 21 and an atomizer 22. Multiple atomizing tubes 21 can be provided. The atomizing tubes 21 are arranged along the top and / or side of the reactor 1. One atomizer 22 can be installed on the atomizing tube 21, or multiple atomizers 22 can be installed at intervals. The atomizing tube 21 is connected to the liquid collection area 12 or an external raw water tank through a circulation pipeline. A liquid pressurization and delivery assembly is provided on the circulation pipeline. The liquid pressurization and delivery assembly includes an ozone-resistant liquid pressurization pump, a filter, a flow regulating valve, and a check valve. The liquid pressurization pump delivers the liquid to be treated to the atomizing tube 21 and sprays it towards the gas phase reaction zone 13 through the atomizer 22, so that the liquid forms micro-droplets with a median volume droplet size of 10 to 200 μm. The spray direction can be downward, oblique, or staggered. The coverage areas of multiple atomizers 22 overlap to reduce the spray blind zone in the gas phase reaction zone.

[0026] The ozone generating module includes an ozone generator 31, which is located outside the reactor 1 or installed on the outside of the reactor 1. The reactor 1 is provided with an inlet, and the outlet of the ozone generator 31 is connected to the reaction chamber through the inlet. The ozone generator 31 may include a matching gas source treatment and pressurization supply component. Ozone can be introduced into the reaction chamber before the working state to complete the pre-charge, or it can be continuously introduced during the working process. The continuously introduced ozone is used to supplement the ozone consumption caused by direct oxidation, ultraviolet photolysis, and natural decomposition, so that gaseous ozone... The concentration is maintained within the set range; the ozone detection module includes an ozone detector 61, which is connected to the gas phase reaction zone 13 through a detection port to detect the gas phase ozone concentration. The set value of the gas phase ozone concentration is determined according to the type of pollutant, the quality of the influent water, the droplet size, and the residence time, and is jointly regulated by the output and exhaust volume of the ozone generator 31. The gas phase ozone concentration is expressed in ppm or mg / m³; when detecting dissolved ozone in the liquid phase, it is expressed in mg / L to avoid mixing the gas phase and liquid phase concentration units.

[0027] The ultraviolet irradiation module includes an ultraviolet lamp strip 41, which is installed on the inner wall of the reactor 1 and located above the highest water level line 11. Multiple sets of ultraviolet lamp strips 41 can be installed. The ultraviolet lamp strip 41 is equipped with an ultraviolet-transmitting quartz protective sleeve and an ozone-resistant seal. An ultraviolet reflective surface is provided on the inner wall of the reactor 1, so that the ultraviolet light is reflected multiple times in the gas phase reaction zone, thereby expanding the irradiation range of micro-droplets. The ultraviolet lamp strip 41 can use an ultraviolet light source in the 185 nm, 254 nm or other 185-365 nm wavelength band; the power of a single set can be 10-200 W.

[0028] The pressure detection and regulation module includes a pressure gauge 51 and an exhaust control component. The pressure gauge 51 is located above the reactor 1, with its end extending into the reaction chamber. The exhaust control component includes an exhaust port 52 on the reactor 1, positioned above the highest water level line 11. The exhaust port 52 is connected to the ozone tail gas decomposition device via a pressure regulating valve, allowing tail gas to be discharged from the reaction chamber. When the ozone input exceeds the controlled exhaust volume, the pressure inside the sealed reaction chamber increases. The ozone intake and exhaust volumes are adjusted based on the readings from the pressure gauge 51 to maintain the pressure inside the reactor 1 at 0.01–0.30 MPa, preferably 0.02–0.31 MPa. The operating pressure of the safety relief device is higher than the normal operating pressure but does not exceed the design allowable pressure of the reactor 1.

[0029] The suspended catalytic module 7 is positioned in the droplet movement path below the atomizer 22 and is spaced apart from the liquid collection area 12. The suspended catalytic module 7 includes a catalytic support and catalytic material disposed on the catalytic support. The catalytic support can be a mesh, sheet, strip, or porous structure, and can be made of stainless steel mesh, ceramic, porous carbon material, or ozone-resistant polymer material. The catalytic material can be TiO2, ZnO, manganese oxide, iron oxide, carbon-based catalytic material, or a combination thereof. The catalytic support can be installed in the reaction chamber through a detachable bracket for cleaning and replacement.

[0030] The fan 18 is located at the rear or side of the reactor 1 and above the highest water level 11. An ozone-resistant sealing and isolation structure is provided between the driving component of the fan 18 and the reaction chamber. The impeller or the component in contact with ozone is made of ozone-resistant material. The fan 18 drives the circulation of ozone gas in the gas phase reaction zone, making the ozone concentration and droplet distribution more uniform.

[0031] The operation process of this embodiment is as follows: S1, liquid inlet, close the outlet 15, and introduce the liquid to be treated into the collection area through the inlet 14 and make the liquid level lower than the highest water level line 11. S2, ozone is input. Before the atomization process begins, ozone generator 31 and fan 18 are started. Ozone is input into the reaction chamber through ozone generator 31 to replace the original gas in the reaction chamber and to pre-form an ozone atmosphere in the gas phase reaction zone. S3, Ozone input pressurization, continuously input ozone into the reaction chamber to increase the pressure inside reactor 1. By adjusting the ozone inlet flow rate and the exhaust flow rate of exhaust port 52, the pressure inside reactor 1 is slowly increased to the set range of 0.01~0.30MPa. Pressure gauge 51 continuously monitors the pressure in the reaction chamber, and ozone detector 61 continuously monitors the gas phase ozone concentration in the reaction chamber. S4, atomization and ultraviolet reaction, start the liquid pressurization and delivery component and ultraviolet lamp strip 41, the liquid to be treated in the collection area enters the atomization tube 21 and is sprayed by the atomizer 22 to form micro-droplets. The droplets come into contact with ozone in the gas phase reaction zone, are irradiated by the ultraviolet lamp strip 41, and come into contact with the catalytic material. S5, collection and circulation: the droplets after the reaction flow into the collection area under the action of gravity and can be circulated and atomized multiple times. S6, shutdown and discharge: After the set treatment time is reached or the water quality meets the standard, the ozone generator 31 and the liquid pressurization and delivery component are stopped, the fan 18 continues to run, and the exhaust gas is sent to the ozone exhaust gas decomposition device through the exhaust port 52. After the pressure inside the reaction chamber is reduced to balance with the outside and the ozone concentration reaches the safe condition, the treated liquid is discharged from the outlet 15 and the fan 18 is turned off. During the atomization process, ozone can be continuously introduced into the reaction chamber to replenish the ozone consumed by the reaction and maintain the set ozone concentration. Example

[0032] like Figures 8-11 As shown, the reactor 1 in this embodiment adopts a cylindrical, sealed, pressure-resistant structure. The atomizing tube 21 can be arranged circumferentially and axially, and the atomizer 22 sprays towards the central area of ​​the cylinder; the suspended catalytic module 7 is spaced apart along the circumferential direction; the ultraviolet lamp strip 41 is arranged circumferentially or axially along the inner wall of the cylinder; the fan 18 is located at the rear of the reactor 1, and the functions and connections of the water inlet 14, water outlet 15, highest water level line 11, ozone generator 31, air inlet, pressure gauge 51, ozone detector 61, detection port, and exhaust port 52 are the same as in embodiment 1.

[0033] A cylindrical reactor 1 is advantageous for withstanding internal positive pressure, but the present invention is not necessarily limited to a cylindrical shape. For reactors 1 with square, polygonal, or other shapes, the design pressure requirements can be achieved by adding reinforcing ribs, rounded corner transitions, or an external pressure-bearing frame. The material, wall thickness, connection method, and safety relief parameters of reactor 1 should be determined based on the volume, operating pressure, and applicable specifications.

[0034] Example 3: Sample Operating Parameters Taking water containing recalcitrant organic pollutants as an example, the median particle size of the atomized droplets can be set to 20–100 μm, the internal pressure of reactor 1 can be set to 0.02–0.20 MPa, the wavelength of the ultraviolet light source can be set to 254 nm, and an ultraviolet lamp group of 10–200 W can be configured according to the effective volume of reactor 1.

[0035] First, input ozone and turn on fan 18. After the gas phase ozone concentration reaches the preset value, start the atomization cycle and ultraviolet lamp 41. The treatment time can be determined according to the pollutant removal rate, ozone utilization rate or effluent index. The above parameters are only used to illustrate the possible implementation methods and do not constitute a limitation on the scope of protection of the present invention.

[0036] It should be understood that the appearance, number of atomizers, number of ultraviolet lamps, number of catalytic modules and their arrangement of reactor 1 can all be adjusted according to the processing scale; as long as a closed positive pressure ozone phase reaction zone is used, so that the liquid to be treated reacts synergistically with ozone and ultraviolet light after atomization, it is all within the concept of this invention.
