DETAILED DESCRIPTION

[0021] The technical solutions of the present application will be described clearly and completely below in combination with the drawings of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Please refer to the drawings of the present application Figures 1-6 The embodiment of the present application provides a space gas particle differentiation system, comprising: The gas particle separation module comprises an air inlet 1, a cyclone separation cylinder 2 and a detachable dust collection cylinder 3. The cyclone separation cylinder 2 separates the particulate matter in the air by centrifugal force. The separated particulate matter falls into the bottom dust collection cylinder 3. The ultraviolet catalysis module comprises an ultraviolet reaction chamber 4. The inner wall of the ultraviolet reaction chamber 4 is coated with a photocatalyst and is configured with a UV-C light source for decomposing organic pollutants and microorganisms. The electron-ozone reaction module comprises an electron acceleration section 5, an ozone acceleration section 6, an electron generator 7, an ozone generator 8, an electron emitter 10 and an ozone emitter 11. The electron acceleration section 5 and the ozone acceleration section 6 accelerate the electron flow and the ozone flow to the reaction chamber 12 by high-voltage electric field, respectively. The air flow circulation module comprises a mixed flow pipeline fan 13 and an air outlet 14. The mixed flow pipeline fan 13 forms a negative pressure air flow in the system. The purified air is discharged through the air outlet 14.

[0023] Specifically, in the gas particle separation module, after the air enters the system through the air inlet 1, it first flows through the cyclone separation cylinder 2. The cyclone separation cylinder 2 uses centrifugal force to separate the particulate matter. The particulate matter (such as dust and pollen) is thrown to the cylinder wall in high-speed cyclone and settles along the wall, finally falling into the bottom detachable dust collection cylinder 3. The smaller particulate matter continues to enter the subsequent processing link with the airflow, thereby significantly reducing the subsequent processing load through physical separation, without relying on consumables such as HEPA filter screens, reducing maintenance costs, and the detachable dust collection cylinder 3 is easy to clean regularly, avoiding secondary pollution.

[0024] The inner wall of the UV reaction chamber 4 in the UV catalytic module is coated with nanoscale photocatalyst (such as titanium dioxide). Under the irradiation of the UV-C light source, the photocatalyst absorbs photon energy to generate electron-hole pairs, which react with water molecules and oxygen in the air to produce active oxygen free radicals. The active oxygen free radicals can efficiently decompose volatile organic compounds (VOCs), odor molecules, and microbial cell membranes / genetic material, achieving the mineralization of organic pollutants (conversion to CO2 and H2O) and the inactivation of bacteria / viruses. The UV-C light source directly damages the DNA / RNA structure of microorganisms, and the dual action ensures no chemical residues and secondary pollution. In the electronic-ozone reaction module, the electron generator 7 generates a high-speed electron stream in the electron acceleration section 5 through a high-voltage electric field, which is injected into the reaction chamber 12 through the electron emitter 10. The ionized pollution particles are charged and agglomerated. The ozone generator 8 ionizes oxygen to generate ozone in the ozone acceleration section 6, which is injected into the reaction chamber 12 through the ozone emitter 11. The strong oxidizing property of ozone can decompose bacteria, viruses, and odor molecules. The electron stream and ozone form a reverse vortex in the reaction chamber 12, promoting collision reactions and mutual decomposition, which not only enhances the purification efficiency but also avoids the escape of excess electrons and ozone. In the air flow circulation module, the mixed flow pipe fan 13 forms a stable negative pressure in the system, driving the air flow to pass through each processing module in turn, ensuring that the pollutants and reaction substances (electrons, ozone, and free radicals) are fully mixed and contacted. The fan speed can be dynamically adjusted to control the air flow speed and improve the decomposition efficiency. At high speed, the processing flux is increased to adapt to high pollution scenarios. The purified air is discharged through the exhaust port 14.

[0025] A gas sensor is provided at the outlet of the exhaust port 14 to detect air quality. An ozone sensor is provided at the outlet of the reaction chamber 12 to detect ozone concentration.

[0026] Specifically, the gas sensor at the outlet of the exhaust port 14 detects the particulate matter concentration and volatile organic content of the purified air in real time, and feeds the data back to the electrical control system controller 15 to form a terminal closed-loop control. The ozone sensor 11 at the outlet of the reaction chamber 12 monitors the ozone concentration generated during the reaction in real time and feeds the data back to the electrical control system controller 15. When the ozone concentration exceeds the preset safety threshold, the electrical control system controller 15 immediately reduces the output power of the ozone generator 8 or shuts it down. At the same time, the mixed flow pipe fan 13 is accelerated to dilute the residual ozone, preventing excess ozone from escaping to the external environment through the exhaust port 14, and eliminating the potential harm to the respiratory system and the ecological environment.

[0027] The system also includes an electrical control system controller 15, which includes an air pollution particle control system, an ozone concentration control system and an air flow control system, and all use closed-loop control methods and are controlled by an FPGA or a single-chip microcomputer. Users control it through a physical application interface and a software application interface, which interacts with the FPGA or the single-chip microcomputer through a program application interface.

[0028] Specifically, the electrical control system controller 15 integrates the air pollution particle control system, the ozone concentration control system and the air flow control system, takes the FPGA or the single-chip microcomputer as the core, uses the closed-loop control method to real-time coordinate the operation of the gas-particle separation module, the ultraviolet catalysis module, the electron-ozone reaction module and the air flow circulation module, dynamically adjusts the electron emission intensity of the electron generator 7, the ozone generation rate of the ozone generator 8 and the air flow speed of the mixed flow pipe fan 13 based on the feedback data of the gas sensor at the exhaust port 14 and the ozone sensor 11 at the reaction chamber 12, ensures efficient decomposition of pollution particles while strictly inhibiting ozone concentration, and sends instructions through the program application interface by the physical application interface or the software application interface. After the controller 15 analyzes the instructions, it optimizes the parameters of each module to realize precise purification without consumables and low maintenance, and supports integration with other systems through the interface to expand into an intelligent air purification network.

[0029] The air pollution particle control system controls the number of electrons generated by the electron generator 7 through a closed-loop control architecture.

[0030] Specifically, the air pollution particle control system adjusts the number of electrons released by the electron generator 7 in real time through a closed-loop control architecture, transmits the feedback data of the pollution particle concentration detected by the gas sensor to the electrical control system controller, generates a control signal by the FPGA or the single-chip microcomputer, dynamically controls the high-voltage output power of the electron generator 7 and the electron flow intensity of the electron emitter 10, and the electrons are accelerated by the high-voltage line 9 and shot into the reaction chamber 12, collide with the pollution particles and make them charged and agglomerate or ionize and decompose, while the number of electrons is accurately controlled to avoid excessive electrons causing equipment overload or energy waste.

[0031] The ozone concentration control system controls the generation of ozone concentration by the ozone generator 8 through a closed-loop control architecture, and the ozone concentration control system has a safety mechanism. When the ozone concentration is higher than the set safety value, the ozone generator is temporarily turned off.

[0032] Specifically, the ozone concentration control system monitors the ozone concentration at the outlet of the reaction chamber 12 in real time through a closed-loop control architecture, dynamically adjusts the power output of the ozone generator 8 such as adjusting the high-voltage field strength or the ultraviolet lamp irradiation time, and ensures that the ozone generation amount accurately matches the purification demand.

[0033] Air flow control system, for controlling the mixed flow duct fan 13 to change the pressure, while changing the mixing speed of the electrons or ozone in the reaction chamber 12 by changing the speed of part of the airflow.

[0034] Air flow control system, for controlling the mixed flow duct fan 13 to change the pressure, while changing the mixing speed of the electrons or ozone in the reaction chamber 12 with pollutants.

[0035] Specifically, the air flow control system dynamically adjusts the speed of the mixed flow duct fan 13 through a closed-loop control architecture to change the airflow pressure and flow rate in the system, such as increasing the wind speed to increase the air treatment flux in high pollution scenarios, and reducing the wind speed to prolong the reaction time of the electron acceleration section 5 and the ozone acceleration section 6 in low pollution scenarios, while adjusting the airflow direction or local flow rate to optimize the mixing uniformity of the electron flow of the electron emitter 10 and the ozone of the ozone emitter 11 in the reaction chamber 12, ensuring that the electrons and ozone fully contact the pollution particles, improving the decomposition efficiency, and reducing ozone residue.

[0036] Program application interface enables components such as physical application interface and software application interface to communicate with the system, and other systems such as building heating, ventilation and air conditioning systems can also be integrated into the system through this interface.

[0037] Specifically, the program application interface serves as a communication bridge between the system and internal and external components, enabling data interaction between the physical application interface and the software application interface and the electrical control system controller 15 through standardized protocols, allowing users to send control instructions and obtain real-time system operation status through multiple terminals; at the same time, the interface supports seamless integration with third-party systems, triggering collaborative control through data sharing, thereby achieving fine control of global air quality and improving operation and maintenance efficiency.

[0038] Physical application interface, including OLED display screen 17 and button 16, for inputting start-up instructions and reading system status.

[0039] Specifically, the physical application interface receives user input start, stop, mode switching and other instructions through the button 16, and displays the system operation status in real time through the OLED display screen 17, forming a direct channel for human-computer interaction.

[0040] Software application interface, users input start-up instructions and read system status through software application programs, including mobile applications or web applications, through wired or wireless protocols.
