Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a system and method for the synergistic treatment of waste gas and wastewater based on nuclear photonic radiation. Background Technology

[0002] With the acceleration of industrialization, large amounts of industrial waste gas generated by industries such as petrochemicals, pharmaceutical manufacturing, and surface coating have become one of the main sources of air pollution. These waste gases typically contain volatile organic compounds (VOCs), odorous substances, and other complex components, characterized by large concentration fluctuations, complex composition, and difficulty in biodegradation, posing a serious threat to the ecological environment and human health.

[0003] Currently, industrial waste gas treatment technologies mainly include adsorption, catalytic combustion, biodegradation, and plasma oxidation. While adsorption can effectively enrich pollutants, it requires regeneration or disposal of secondary solid waste after adsorption saturation. Catalytic combustion has high energy consumption for treating low-concentration waste gases, and the catalyst is prone to poisoning and inactivation. Biological methods are limited by microbial activity, resulting in low removal efficiency for hydrophobic or recalcitrant organic matter. Conventional plasma technology, while generating high-energy electrons and active groups, is insufficient for treating high-concentration or complex waste gases and easily produces byproducts, posing a risk of secondary pollution.

[0004] In summary, existing waste gas treatment technologies struggle to balance treatment efficiency, energy consumption control, and secondary pollution prevention, particularly lacking a universally applicable deep purification method capable of efficiently, rapidly, and without secondary pollution for low-concentration, recalcitrant organic waste gases. Therefore, developing a novel waste gas treatment system to achieve efficient, rapid, and pollution-free deep purification of waste gases using an energy source has become a pressing technical challenge in this field. Summary of the Invention

[0005] To address the problems existing in the prior art, a co-treatment system and method for waste gas and wastewater based on nuclear photonic energy excitation is provided. By setting up a cyclone generator to adjust the rotation path length of the waste gas when it enters the treatment chamber, the residence time of the waste gas can be precisely controlled. Combined with the synergistic effect of nuclear photonic energy and high-voltage electric field, the problems of low waste gas treatment efficiency, uncontrollable residence time, and difficulty in adapting to the treatment needs of different waste gas components in the prior art are solved.

[0006] To address the problems of existing technologies, this invention provides a waste gas treatment system based on nuclear photonic radiation excitation, comprising: a reaction chamber containing a reaction cavity; an inlet duct, one end of which is located outside the reaction chamber, and the other end of which penetrates the reaction chamber and extends into the reaction cavity to form an outlet port; and an outlet duct, one end of which penetrates the reaction chamber and extends into the reaction cavity to form an inlet port, and the other end of which is located outside the reaction chamber; the outlet port of the inlet duct and the inlet port of the outlet duct are arranged opposite to each other and form a gap between them. The system includes a processing chamber of predetermined length; a nuclear photoelectric ray generator disposed within the reaction chamber with its ray-generating end facing the processing chamber; a high-voltage electrode assembly disposed within the reaction chamber for applying a high-voltage electric field to the processing chamber; and a vortex generator disposed at the air inlet port of the air outlet duct, comprising a flow-guiding structure circumferentially distributed along the inner wall of the air outlet port of the air inlet duct. The flow-guiding structure has an adjustable degree of freedom to change the airflow guiding angle, thereby adjusting the rotation path length of the waste gas within the processing chamber to regulate the residence time of the waste gas within the processing chamber. The flow-guiding vane extends axially along the air inlet duct and has a predetermined width radially along the air inlet duct. One end of the flow-guiding vane is fixedly connected to the inner wall of the air inlet duct, and the other end is a movable end capable of circumferentially swinging relative to the air inlet duct about its axis.

[0007] Preferably, the vortex generator further includes: an adjusting ring, coaxially rotatably disposed on the outside of the air inlet duct, the movable end of the guide vane being connected to the adjusting ring; and a rotary drive assembly, disposed outside the reaction chamber, the drive end of which is drively connected to the adjusting ring.

[0008] Preferably, the adjusting ring has a insertion groove at one end facing the air outlet of the air inlet pipe, and the insertion groove extends circumferentially along the adjusting ring; the movable end of the guide plate extends radially outward along the air inlet pipe and then extends axially along the air inlet pipe to form an insertion piece; the insertion piece is inserted into the insertion groove and slides in cooperation with the insertion groove.

[0009] Preferably, the rotary drive assembly includes: an arc-shaped rack coaxially disposed on the outer periphery of the adjusting ring; a worm gear rotatably disposed in the reaction chamber and meshing with the arc-shaped rack, one end of the worm gear extending outside the reaction chamber; and a motor disposed outside the reaction chamber, with its output shaft connected to the worm gear drive.

[0010] Preferably, the end of the adjusting ring facing away from the air outlet duct is provided with a stepped groove, and the vortex generator further includes two semi-circular clamps coaxially disposed on the outer wall of the air inlet duct, the two semi-circular clamps being rotatably connected to the stepped groove in a circular ring shape.

[0011] Preferably, the air outlet port of the air inlet duct is coaxially arranged with the air inlet port of the air outlet duct; the diameter of the air outlet port of the air inlet duct is smaller than the diameter of the air inlet port of the air outlet duct.

[0012] Preferably, the nuclear photoelectric beam generator is configured to generate a beam with an energy range of 2.0 MeV to 2.5 MeV and a beam current intensity range of 40 mA to 50 mA. Preferably, the electric field voltage generated by the high-voltage electrode assembly within the processing chamber is not less than 2.5 megavolts.

[0013] The waste gas treatment method based on nuclear photonic energy excitation employs a waste gas treatment system based on nuclear photonic energy excitation, and includes the following steps: Step 1: Introduce the waste gas to be treated into the reaction chamber through the air inlet pipe, and discharge the waste gas from the air outlet port of the air inlet pipe; Step 2: Adjust the airflow guiding angle of the guide structure through the cyclone generator so that the exhaust gas enters the treatment chamber with a preset rotation path length; Step 3: Activate the nuclear photoelectric ray generator to irradiate the processing cavity with nuclear photoelectric rays. At the same time, activate the high-voltage electrode assembly to apply a high-voltage electric field to the processing cavity. The nuclear photoelectric rays and the high-voltage electric field work together to excite and generate active oxygen, ozone and hydroxyl radicals, which oxidize and decompose the waste gas molecules. Step 4: The treated clean gas enters the air outlet duct through the air inlet port and is discharged to the outside of the reaction chamber.

[0014] The advantages of this application compared to the prior art are: This application achieves precise control of the waste gas residence time by adjusting the rotation path length of the waste gas using a cyclone generator. This allows waste gases of different compositions and concentrations to achieve optimal treatment results, significantly improving the system's adaptability and treatment efficiency. The synergistic effect of nuclear photon energy rays and a high-voltage electric field can generate high-concentration active particles within milliseconds, achieving rapid and deep oxidation of the waste gas and avoiding the long treatment cycles of traditional processes. The rotating airflow increases the contact probability and contact time between waste gas molecules and active particles, making the treatment more thorough and preventing incomplete treatment due to insufficient residence time. The entire treatment process requires no chemical reagents and does not generate secondary pollution, achieving green and environmentally friendly waste gas purification. The system has high integration, stable and reliable operation, and is suitable for the comprehensive treatment of recalcitrant industrial waste gases in industries such as petrochemicals, pharmaceutical manufacturing, and surface coating.

[0026] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 6As shown, a waste gas treatment system based on nuclear photonic radiation excitation includes: a reaction chamber 1, which has a reaction cavity inside; an air inlet duct 2, one end of which is located outside the reaction chamber 1, and the other end of which passes through the reaction chamber 1 and extends into the reaction cavity to form an air outlet port; and an air outlet duct 3, one end of which passes through the reaction chamber 1 and extends into the reaction cavity to form an air inlet port, and the other end of which is located outside the reaction chamber 1; the air outlet port of the air inlet duct 2 and the air inlet port of the air outlet duct 3 are arranged opposite each other and form a predetermined length between them. The system includes: a processing chamber; a nuclear photoelectric ray generator 4, disposed within the reaction chamber 1 with its ray-generating end facing the processing chamber; a high-voltage electrode assembly, disposed within the reaction chamber 1, used to apply a high-voltage electric field to the processing chamber; and a vortex generator 5, disposed at the air inlet port of the air outlet duct 3, comprising a flow guide structure circumferentially distributed along the inner wall of the air outlet port of the air inlet duct 2, the flow guide structure having an adjustable degree of freedom to change the airflow guiding angle, used to adjust the rotation path length of the exhaust gas within the processing chamber, thereby adjusting the residence time of the exhaust gas within the processing chamber.

[0028] The system includes a reaction chamber 1, which contains a reaction cavity to provide a closed reaction space for waste gas treatment. One end of an inlet duct 2 is located outside the reaction chamber 1, and the other end penetrates the reaction chamber 1 and extends into the reaction cavity to form an outlet port for introducing the waste gas to be treated into the reaction cavity. One end of an outlet duct 3 penetrates the reaction chamber 1 and extends into the reaction cavity to form an inlet port, and the other end is located outside the reaction chamber 1 to discharge the treated clean gas. The outlet port of the inlet duct 2 and the inlet port of the outlet duct 3 are positioned opposite each other, forming a treatment cavity of predetermined length between them. This treatment cavity is the core area for receiving and treating the waste gas.

[0029] The nuclear photoelectric ray generator 4 is located inside the reaction chamber 1, with its ray-generating end facing the processing cavity. It is used to emit high-energy rays into the processing cavity to excite gas molecules to produce ionization and excitation. The high-voltage electrode assembly is located inside the reaction chamber 1 and is used to apply a high-voltage electric field to the processing cavity. It works synergistically with the nuclear photoelectric ray to excite and generate highly oxidizing reactive particles such as reactive oxygen species, ozone, and hydroxyl radicals within milliseconds.

[0030] The vortex generator 5 is located at the air inlet of the air outlet duct 3. It includes a flow guide structure distributed circumferentially along the inner wall of the air outlet of the air inlet duct 2. This flow guide structure has the degree of freedom to adjust the airflow guiding angle. By adjusting the guiding angle of the flow guide structure, the rotation path length of the exhaust gas when it enters the treatment chamber can be changed, thereby precisely controlling the residence time of the exhaust gas in the treatment chamber.

[0031] During operation, the waste gas to be treated is introduced into the reaction chamber through the inlet duct 2 and discharged from the outlet port of the inlet duct 2. Before entering the treatment chamber, the cyclone generator 5 adjusts the guiding angle of the guide structure according to the composition of the waste gas and the treatment requirements, so that the waste gas enters the treatment chamber with a preset rotation path length. The waste gas moves forward in a rotating state in the treatment chamber, while being irradiated by nuclear light rays and subjected to the action of a high-voltage electric field. Under the synergistic excitation of high-energy rays and high-voltage electric field, a large amount of active oxygen, ozone and hydroxyl radicals are generated in the treatment chamber. These active particles come into full contact with the waste gas molecules, breaking the molecular bonds of complex organic matter and deeply oxidizing it into carbon dioxide and water. The treated clean gas enters the outlet duct 3 through the inlet port of the outlet duct 3 and is finally discharged to the outside of the reaction chamber 1.

[0032] In a treatment chamber of fixed length, the residence time of exhaust gas typically depends on the airflow velocity and the chamber length. This solution utilizes an adjustable-angle guide structure to allow the exhaust gas to enter the treatment chamber along a spiral trajectory at different angles. When the guide structure is adjusted to a larger angle, the exhaust gas moves forward along a large-angle spiral path, and its actual travel path length is significantly greater than the straight-line length of the treatment chamber, thus extending the residence time within the chamber. Conversely, when the guide structure is adjusted to a smaller angle, the exhaust gas spiral path becomes gentler, and the actual path length approaches the straight-line length of the treatment chamber, resulting in a correspondingly shorter residence time.

[0033] During operation, the spiral angle of the exhaust gas entering the treatment chamber is controlled by adjusting the guiding angle of the flow guiding structure, based on the composition, concentration, and ease of oxidation of the exhaust gas. For high-concentration exhaust gas that is difficult to degrade, increasing the flow guiding angle causes the exhaust gas to move along a large spiral path, extending its residence time in the region of synergistic effect of high-energy rays and electric field, ensuring sufficient oxidation; for low-concentration exhaust gas that is easy to treat, decreasing the flow guiding angle appropriately shortens the residence time, improving treatment efficiency while ensuring treatment effect.

[0034] like Figures 6 to 10 As shown, preferably, the guide vane 51 extends along the axial direction of the air inlet pipe 2 and has a predetermined width along the radial direction of the air inlet pipe 2; one end of the guide vane 51 is fixedly connected to the inner wall of the air inlet pipe 2, and the other end is a movable end, which can swing circumferentially relative to the air inlet pipe 2 around the axis of the air inlet pipe 2.

[0035] During operation, when it is necessary to increase the length of the exhaust gas rotation path, the movable end of the drive guide vane 51 is swung circumferentially to a larger angle, causing the airflow to generate a stronger tangential velocity as it passes through the guide vane 51, resulting in vigorous rotation. When it is necessary to reduce the length of the rotation path, the movable end is swung to a smaller angle, allowing the airflow to enter the treatment chamber in a weaker rotational state. The swaying angle of the guide vane 51 can be precisely adjusted according to the exhaust gas composition, concentration, and treatment requirements, achieving continuous adjustability of the rotation path length.

[0036] The cantilever structure of the guide vane 51, with one end fixed and the other swinging, is simple and reliable, with fewer moving parts, reducing manufacturing and maintenance costs. By changing the guiding angle through circumferential swing, stepless adjustment of the airflow rotation path length is achieved, offering a wide adjustment range and high precision to meet the treatment needs of different waste gases. The axial extension design of the guide vane 51 ensures sufficient guidance of the airflow as it passes through it, avoiding the insufficient guidance problem caused by short guide vanes 51. The radial width design of the guide vane 51 balances guiding effect and airflow resistance, minimizing pressure loss while ensuring effective guidance. Multiple guide vanes 51 are evenly distributed circumferentially, ensuring uniform and symmetrical airflow rotation and avoiding uneven treatment problems caused by eccentric rotation.

[0037] like Figure 7 and Figure 9 As shown, preferably, the vortex generator 5 further includes: an adjusting ring 52, which is coaxially rotatably disposed on the outside of the air inlet duct 2, and the movable end of the guide vane 51 is connected to the adjusting ring 52; and a rotation drive assembly 53, which is disposed outside the reaction chamber 1, and its drive end is connected to the adjusting ring 52 in a transmission manner.

[0038] During operation, the operator or control system outputs driving force through the rotary drive assembly 53 to drive the adjusting ring 52 to rotate, according to the waste gas treatment requirements. The rotation of the adjusting ring 52 causes the movable ends of all the guide vanes 51 connected to it to swing synchronously in the circumferential direction, thereby precisely changing the guiding angle of each guide vane 51. After the angle of the guide vane 51 changes, the rotation path length of the waste gas entering the treatment chamber changes accordingly, realizing online adjustment of the waste gas residence time. The rotary drive assembly 53 is located outside the reaction chamber 1, which facilitates operation and maintenance, and avoids the influence of the harsh internal environment on the drive mechanism.

[0039] The synchronous linkage of all guide vanes 51 is achieved through the adjusting ring 52, ensuring the consistency of the angle changes of each guide vane 51 and avoiding airflow deviation or uneven rotation caused by inconsistent angles. The external design of the rotation drive assembly 53 allows operators to complete the adjustment without entering the reaction chamber, improving operational convenience and safety, while also facilitating heat dissipation and maintenance of the drive assembly. The connection structure between the adjusting ring 52 and the guide vanes 51 is simple and reliable, with a short transmission path, reducing transmission gaps and energy losses, and improving adjustment accuracy and response speed. This design enables online real-time adjustment of the guide angle, allowing the system to dynamically optimize the rotation intensity according to changes in exhaust gas parameters, always maintaining the best treatment effect. The overall structure is compact, does not occupy internal space of the treatment chamber, and avoids interference with airflow from additional structures.

[0040] like Figure 8As shown, preferably, the adjusting ring 52 has a insertion groove 521 at one end facing the air outlet port of the air inlet pipe 2, and the insertion groove 521 extends circumferentially along the adjusting ring 52; the movable end of the guide plate 51 extends radially outward along the air inlet pipe 2 and then extends axially along the air inlet pipe 2 to form an insertion piece 511; the insertion piece 511 is inserted into the insertion groove 521 and slides in cooperation with the insertion groove 521.

[0041] During operation, when the rotary drive assembly 53 drives the adjusting ring 52 to rotate around the axis of the air inlet duct 2, the insertion slot 521 rotates synchronously with the adjusting ring 52. Since the insertion piece 511 is inserted into the insertion slot 521, the circumferential movement of the insertion slot 521 drives the movable end of the guide vane 51 to swing synchronously through the insertion piece 511. The insertion piece 511 can slide freely circumferentially within the insertion slot 521, accommodating the relative movement between the guide vane 51 and the adjusting ring 52 during the swinging process.

[0042] The sliding fit structure of the insertion slot 521 and the insertion piece 511 is simple and reliable, eliminating the need for complex hinges or fasteners, thus reducing manufacturing costs and assembly difficulty. The L-shaped insertion piece 511 design ensures a stable connection between the guide vane 51 and the adjusting ring 52, while allowing for adaptive adjustment of their relative positions during movement, avoiding jamming or interference. The insertion slot 521 extends continuously circumferentially along the adjusting ring 52, ensuring a reliable connection between the guide vane 51 and the adjusting ring 52 at any swing angle, guaranteeing consistent and reliable transmission. This connection method facilitates the installation and removal of the guide vane 51; during maintenance, simply pull the insertion piece 511 out of the insertion slot 521 without disassembling the entire adjusting ring 52. The sliding fit between the insertion piece 511 and the insertion slot 521 has a certain self-lubricating property, maintaining smooth movement even after long-term operation, reducing maintenance frequency.

[0043] like Figure 7 and Figure 9 As shown, preferably, the rotary drive assembly 53 includes: an arc-shaped rack 531, coaxially disposed on the outer periphery of the adjusting ring 52; a worm gear 532, rotatably disposed in the reaction chamber and meshing with the arc-shaped rack 531, one end of the worm gear 532 extending outside the reaction chamber 1; and a motor 533, disposed outside the reaction chamber 1, with its output shaft connected to the worm gear 532 in a transmission manner.

[0044] During operation, after the motor 533 starts, it drives the worm gear 532 to rotate around its own axis. The worm gear 532 transmits the rotational motion to the adjusting ring 52 through meshing with the arc-shaped rack 531, driving the adjusting ring 52 to rotate around the axis of the air inlet duct 2. The rotation of the adjusting ring 52 then drives the guide vane 51 connected to it to swing synchronously, realizing precise adjustment of the guide angle. The self-locking characteristic of the worm gear 532 transmission allows the adjusting ring 52 to stop at any angle without the need for an additional braking device. By controlling the forward and reverse rotation and the rotation angle of the motor 533, the swing direction and swing angle of the guide vane 51 can be precisely controlled.

[0045] like Figure 6 and Figure 7 As shown, preferably, the end of the adjusting ring 52 facing away from the air outlet duct 3 is provided with a stepped groove, and the vortex generator 5 also includes two semi-circular clamps 54 coaxially disposed on the outer wall of the air inlet duct. The two semi-circular clamps 54 are in a ring shape and are rotatably connected to the stepped groove coaxially.

[0046] During operation, as the adjusting ring 52 rotates around the axis of the air inlet duct 2 under the drive of the rotary drive assembly 53, the stepped groove slides relative to the semi-circular clamp 54. The semi-circular clamp 54 provides radial support and axial restraint for the adjusting ring 52, ensuring that the adjusting ring 52 remains coaxial with the air inlet duct 2 while allowing it to rotate smoothly. The cooperation between the stepped groove and the semi-circular clamp 54 restricts the axial displacement of the adjusting ring 52, preventing it from shifting during rotation.

[0047] like Figure 3 As shown, preferably, the air outlet port of the air inlet duct 2 is coaxially arranged with the air inlet port of the air outlet duct 3; the diameter of the air outlet port of the air inlet duct 2 is smaller than the diameter of the air inlet port of the air outlet duct 3.

[0048] During operation, exhaust gas is ejected at high speed from the small-diameter outlet port of inlet duct 2, forming a jet with high momentum. Because the inlet port of outlet duct 3 has a larger diameter and is coaxial with the jet, even if the jet diffuses slightly during its forward movement, it can still completely enter the inlet port of outlet duct 3. The velocity difference between the jet boundary and the gas inside the treatment chamber creates a suction effect, drawing surrounding active gases into the core area of ​​the jet and enhancing the mixing effect. Simultaneously, the small-inlet, large-outlet design creates a certain negative pressure zone within the treatment chamber, which helps to prolong the residence time of the exhaust gas in the reaction zone.

[0049] Preferably, the nuclear photoelectric ray generator 4 is configured to generate a ray beam with an energy range of 2.0 MeV to 2.5 MeV and a beam current intensity range of 40 mA to 50 mA. The core energy source of this system is a nuclear photoelectric beam generator 4. This generator produces a nuclear photoelectric particle beam (preferably a nuclear photoelectric electron beam) with an energy range of 2.0 MeV to 2.5 MeV through a high-voltage acceleration device, and its maximum beam current intensity can reach 40 mA to 50 mA. This nuclear photoelectric beam has extremely strong penetrating power and energy deposition efficiency, providing the initial driving force for the physicochemical reactions in the subsequent waste gas treatment process.

[0050] Preferably, the electric field voltage generated by the high-voltage electrode assembly within the processing chamber is not less than 2.5 megavolts.

[0051] The exhaust gas purification process occurs in the system's exhaust gas treatment zone. This zone contains two key fields: a nuclear radiation field and a strong alternating electric field (voltage not less than 2.5 MV) established by high-voltage electrode components. Their synergistic effect is as follows: Molecular activation and bond weakening: The industrial waste gas to be treated enters this synergistic field region. Nuclear light rays act directly on the waste gas molecules, transferring high energy directly to the molecules through Compton scattering, electronic excitation, and other effects, putting them into an electronically or vibrationally excited state, thereby significantly weakening or even preparing to break their chemical bonds.

[0052] Strong electric field-induced polarization collisions: Simultaneously, exhaust gas molecules are forcibly polarized in a strong alternating electric field and rotate at high frequency with the direction of the electric field, generating intense intermolecular rotation and frictional collisions. This physical process gives molecules additional kinetic energy and increases the collision probability of active sites.

[0053] Generation of active substances and chain oxidation: Under the synergistic effect of the above two fields, background gas molecules such as oxygen and water vapor in the reaction zone are efficiently ionized and dissociated, instantly generating extremely high concentrations of active oxygen atoms (O), ozone (O3), and hydroxyl radicals (·OH). These strong oxidizing substances undergo chain oxidation reactions with the activated and weakened bond energy of the waste gas pollutant molecules, completely breaking their chemical bonds within milliseconds, and ultimately oxidizing them to generate stable and harmless small molecules such as carbon dioxide (CO2) and water (H2O).

[0054] The waste gas treatment method based on nuclear photonic energy excitation employs a waste gas treatment system based on nuclear photonic energy excitation, and includes the following steps: Step 1: Introduce the waste gas to be treated into the reaction chamber through the air inlet pipe 2, and discharge the waste gas from the air outlet port of the air inlet pipe 2; Step 2: Adjust the airflow guiding angle of the guide structure through the swirl generator 5 so that the exhaust gas enters the treatment chamber with a preset rotation path length; Step 3: Start the nuclear photoelectric energy ray generator 4 to irradiate the processing cavity with nuclear photoelectric energy rays. At the same time, start the high voltage electrode assembly to apply a high voltage electric field to the processing cavity. The nuclear photoelectric energy rays and the high voltage electric field work together to excite and generate active oxygen, ozone and hydroxyl radicals, which oxidize and decompose the waste gas molecules. Step 4: The treated clean gas enters the air outlet duct 3 through the air inlet port and is discharged to the outside of the reaction chamber 1.

[0055] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.

A waste gas treatment method based on nuclear photonic radiation excitation, employing the waste gas treatment system based on nuclear photonic radiation excitation as described in any one of claims 1-4, characterized in that, Includes the following steps: Step 1: Introduce the waste gas to be treated into the reaction chamber through the air inlet pipe, and discharge the waste gas from the air outlet port of the air inlet pipe; Step 2: Adjust the airflow guiding angle of the guide structure through the cyclone generator so that the exhaust gas enters the treatment chamber with a preset rotation path length; Step 3: Activate the nuclear photoelectric ray generator to irradiate the processing cavity with nuclear photoelectric rays. At the same time, activate the high-voltage electrode assembly to apply a high-voltage electric field to the processing cavity. The nuclear photoelectric rays and the high-voltage electric field work together to excite and generate active oxygen, ozone and hydroxyl radicals, which oxidize and decompose the waste gas molecules. Step 4: The treated clean gas enters the air outlet duct through the air inlet port and is discharged to the outside of the reaction chamber.
