Background Technology

[0002] Glow discharge is a process in which a specific gas is ionized to produce plasma by applying a high DC voltage across an electrode plate. During the discharge process, a unique glow is generated. Glow discharge plasma is a low-pressure, low-temperature plasma. Because it contains a large number of high-energy ions such as electrons, ions, and free radicals with active properties, it transfers energy to atoms and molecules through collisions, causing them to dissociate and ionize. In addition, it has a relatively low gas temperature, which can avoid the damage to the catalyst structure and the sintering of metals caused by high temperatures. This method is widely used in the production of catalysts. Summary of the Invention

[0003] To achieve efficient, precise, and intelligent multi-channel glow discharge catalytic reactions, this invention provides an intelligent multi-channel glow discharge device, the technical solution of which is as follows:

[0018] Furthermore, it offers flexible channel usage, allowing for single-channel or multi-channel operation, and even expansion beyond the current number of channels to achieve true multi-channel simultaneous response.

[0019] Furthermore, the electrode spacing is dynamically and precisely controlled through electrode position detection and adaptive adjustment algorithms. Combined with multi-channel fluid monitoring and collaborative feedback mechanisms, the flow rate and droplet size of each channel are independently adjusted in a closed loop. During the discharge process, the voltage, current and fluid parameters are automatically adjusted based on real-time status signals, thereby achieving efficient, intelligent, precise and safe control of the glow discharge process.

[0036] Example 1: Overall structure of intelligent multi-channel glow discharge device, as follows Figure 1 As shown, the intelligent multi-channel glow discharge device of the present invention includes: a high-voltage power supply unit 1; a positive electrode integrated unit 2; a negative electrode integrated unit 3; an electrode position control unit 4; a droplet flow control unit 5; a magnetic stirring unit 6; and an intelligent control unit 7.

[0037] The high-voltage power supply unit 1 includes a high-voltage DC power supply 1.1, providing a stable high-voltage DC power supply for the entire device. The positive electrode integration unit 2 and the negative electrode integration unit 3 integrate the positive and negative electrode components for glow discharge, respectively, achieving a compact structure, safe insulation, and convenient operation. The electrode position control unit 4 can precisely adjust the distance between the positive and negative electrodes to ensure discharge uniformity; the droplet flow control unit 5, through a multi-channel adjustable flow peristaltic pump 5.1 and a peristaltic pump connecting pipe 5.2, delivers droplets to the reaction position at a suitable flow rate, forming a circulation loop; the magnetic stirring unit 6, through a multi-connected magnetic stirring platform 6.1, prevents droplet sedimentation and improves reaction uniformity; the intelligent control unit 7, through a PLC control program, achieves precise intelligent control of each unit, reducing human error.

[0038] Example 2: Positive electrode integrated unit structure and installation, such as Figure 3 , 4 As shown, the positive electrode integrated unit 2 consists of the following components: a positive electrode bakelite insulating base plate 2.1, a positive electrode integrated copper busbar 2.2, an embedded crown spring 2.3, a platinum wire electrode 2.4, and a positive electrode bakelite insulating top plate 2.5. The installation steps are as follows: Insert the embedded crown spring 2.3 into the corresponding hole on the positive electrode bakelite insulating base plate 2.1; fix the positive electrode integrated copper busbar 2.2 to the base plate 2.1 with bolts according to the groove position, while simultaneously pressing the embedded crown spring 2.3 to achieve electrical contact; insert the platinum wire electrode 2.4 into the embedded crown spring 2.3. The embedded crown spring structure both fixes the platinum wire electrode and ensures voltage conduction; cover the base plate and components with the positive electrode bakelite insulating top plate 2.5 and fix it with bolts to avoid exposing high-voltage components and ensure operational safety. Through the above integration, the voltage of each positive electrode channel is evenly distributed, and it can achieve insulation and safety, ensuring stable and reliable glow discharge.

[0039] Negative electrode integrated unit structure and installation, such as Figure 5 , 6As shown, the negative electrode integrated unit 3 includes: a negative electrode bakelite insulating base plate 3.1, a negative electrode integrated copper busbar 3.2, an embedded crown spring 3.3, a quartz capillary tube 3.4, a hollow graphite rod 3.5, a negative electrode bakelite insulating top plate 3.6, an O-ring 3.7, and a 500ml beaker with double top spouts 3.8. The installation steps are as follows: Install the O-ring 3.7 onto the base plate 3.1, and fix the 500ml beaker with double top spouts 3.8 onto the base plate 3.1; insert the embedded crown spring 3.3 into the corresponding hole on the base plate 3.1; insert the hollow graphite rod 3.5 into the hole on the base plate, making it coaxial with the embedded crown spring 3.3; fix the negative electrode integrated copper busbar 3.2 onto the base plate 3.1 with bolts, while simultaneously pressing the hollow graphite rod 3.5 to achieve electrical conduction; pass the quartz capillary tube 3.4 through the hollow graphite rod, and use the embedded crown spring to fix the droplet reaction position; cover the base plate and components with the top plate 3.6, and fix the bolts to prevent high-voltage components from being exposed and to ensure safety. This structure ensures a complete connection of the negative electrode circuit, facilitates adjustment and use, and is very convenient for droplet flow and collection. The droplet flow is smooth and adjustable, and the operation is safe and reliable.

[0040] Droplet flow control, such as Figure 7 As shown, a multi-channel adjustable flow peristaltic pump 5.1, connected to a peristaltic pump pipe 5.2, draws droplets from a 500ml beaker with two upper nozzles 3.8, which then flows through a capillary quartz tube 3.4 to the discharge reaction position. After the reaction, the droplets flow back to the 500ml beaker with two upper nozzles 3.8 along the gap between the outer wall of the quartz capillary tube 3.4 and the hollow graphite rod 3.5, while a multi-link magnetic stirring platform 6.1 prevents sedimentation, achieving a circulating reaction. Droplets flow from the peristaltic pump outlet pipe through the beaker's upper nozzle to the quartz capillary tube, participate in the reaction at the top of the capillary tube, and then return to the inside of the beaker. They then flow through a pipe through the other upper nozzle of the beaker to the peristaltic pump inlet, forming a circulation. The intelligent control system can adjust the flow rate, droplet size, generation interval, and circulation speed in real time, and precisely control the multi-channel fluid through the control unit 7. The entire process operates automatically in a semi-sealed environment, requiring no manual contact, making it highly efficient and safe.

[0041] Intelligent control systems, such as Figure 8As shown, the intelligent control unit 7 uses a PLC controller and includes: a data acquisition module for real-time monitoring of flow rate, voltage, current, and temperature in each channel; an algorithm processing module for running adaptive control algorithms to automatically adjust flow rate and discharge parameters; and a safety monitoring module for continuously monitoring insulation status and abnormal conditions, implementing automatic alarm and cut-off mechanisms. The process involves three steps: First, the reaction begins; second, the system starts with preset settings; third, each component provides feedback parameters (voltage, flow rate, position, temperature, insulation) to reflect the reaction parameters; fourth, each parameter is evaluated, and if the insulation and temperature feedback values ​​are abnormal, the system shuts down. The remaining parameter feedback values ​​are adjusted using an intelligent algorithm, and the reaction parameters are monitored. If the adjusted values ​​exceed preset safety values, the system shuts down again; if the reaction is optimized after adjustment, the reaction continues until the experiment is completed. Through this control, high-precision intelligent operation of the entire device is achieved, improving catalyst modification efficiency and ensuring experimental safety.
