Description

Technical Field

[0001] This utility model relates to the field of plasma ignition system technology, and specifically to an integrated gas-water skid-mounted device for a plasma ignition system. Background Technology

[0002] Plasma ignition systems, as a highly efficient and environmentally friendly ignition technology, have been widely used in energy, industry and other fields. Their stable operation depends on the stable supply of carrier air and the effective cooling of the igniter's anode and cathode.

[0003] Regarding carrier air supply, existing technologies offer solutions to the problem of carrier air pressure fluctuations. For example, patent CN220489211U discloses a carrier air filtration device for a plasma ignition system. This device uses a pressure sensor and regulating valve to regulate pressure, mitigating the problem of unstable compressed air flow to some extent. However, this technology employs a split-type layout, resulting in a large footprint and increased installation difficulty and site costs. Furthermore, its valve regulator uses a pneumatic shut-off valve, which can easily lead to insufficient air supply during pressure reduction operations, thus limiting the power output of the plasma ignition system and affecting the ignition effect.

[0004] Regarding igniter cooling, patent CN203190449U discloses a cooling device for a plasma ignition system. By using parallel cooling water pumps and incorporating shut-off and check valves, the cooling method is optimized, achieving reduced energy consumption and improved operating efficiency. However, this cooling device also employs a split-type layout, further expanding the overall equipment's footprint and making the cooling system and carrier air system independent, thus preventing coordinated control.

[0005] Furthermore, in existing technologies, the carrier air duct and cooling water duct are dispersed and controlled separately, lacking integrated design. On the one hand, it is impossible to monitor key parameters such as temperature, pressure, and flow rate of the anode and cathode cooling systems of the plasma ignition system separately and accurately, making it difficult to detect local anomalies in a timely manner. On the other hand, the operating parameters of the carrier air system and cooling water duct system cannot be monitored in real time, resulting in poor integration and a lag in the overall system regulation response, which further affects the operational stability and safety of the plasma ignition system.

[0006] Therefore, there is an urgent need for a device that is highly integrated, occupies little space, can simultaneously meet the needs of stable air supply and efficient cooling, and can achieve comprehensive parameter monitoring and precise control, so as to solve the many defects of existing technologies. Utility Model Content

[0007] This invention provides an integrated gas-water skid-mounted device for a plasma ignition system, which aims to optimize the layout and reduce the footprint.

[0008] This utility model is achieved through the following technical solution: an integrated gas-water skid-mounted device for a plasma ignition system, comprising a base, an air inlet pipe assembly, a water return pipe assembly, a water inlet pipe assembly, and auxiliary components for intelligent control and monitoring, all integrated and mounted on the base; the air inlet pipe assembly, the water return pipe assembly, and the water inlet pipe assembly each include monitoring elements for monitoring the internal temperature and / or flow rate and / or pressure of the pipe, as well as control elements for controlling the on / off state of the pipe and / or for regulating the pressure of the pipe.

[0009] Compared with existing technologies, this solution has the following advantages and beneficial effects: This solution integrates the air intake pipe assembly (carrier air supply), water intake pipe assembly (cooling water input), return water pipe assembly (cooling water recovery), and auxiliary components into one unit via a base. This optimizes the layout and structure of each component, completely abandoning the separate arrangement of the carrier air system and cooling system in existing technologies. The overall size of the equipment is effectively reduced compared to traditional separate systems, thereby significantly reducing the space requirements, making it particularly suitable for application scenarios with limited space.

[0010] Furthermore, the intake pipe assembly is an intake pipe for conveying carrier air, including monitoring elements disposed on the intake pipe. The monitoring elements include a first intake air valve, a first pressure reducing valve, a second intake air valve, a proportional pressure valve, and a second pressure reducing valve disposed sequentially on the intake pipe. The control elements include an intake pipe pressure gauge, an intake pipe pressure transmitter, and an intake pipe flow meter disposed at the outlet end of the second pressure reducing valve. A bypass is also branched off at the outlet end of the first pressure reducing valve. The bypass is connected to a third intake air valve, and one end of the bypass returns to the inlet end of the second pressure reducing valve.

[0011] Beneficial effects: This solution adopts a multi-stage adjustment architecture consisting of a first pressure reducing valve, a proportional pressure valve, and a second pressure reducing valve, forming a gradient pressure reduction and precise pressure control logic: The first pressure reducing valve initially reduces the pressure of the front-end high-pressure carrier air (compressed air / nitrogen), laying the foundation for subsequent precise adjustment; the proportional pressure valve can be remotely controlled by the existing controller, and the pressure can be dynamically adjusted according to system requirements to achieve flexible pressure adaptation; the second pressure reducing valve finally stabilizes the pressure to the working pressure adapted to the plasma igniter (e.g., 20 kPa), ensuring that the carrier air pressure output has small fluctuations and high stability.

[0012] The multi-stage adjustment design completely solves the contradiction between pressure reduction and air supply caused by the pressure reduction of pneumatic shut-off valve in the existing technology. By reducing pressure in stages, it avoids the air loss caused by excessive pressure reduction in a single step. While ensuring that the pressure meets the standard, it ensures that the carrier air supply is sufficient, providing a continuous and stable air source support for the plasma ignition system. This avoids problems such as limited ignition power and ignition failure caused by insufficient air supply, and significantly improves ignition efficiency and reliability.

[0013] The second pressure reducing valve integrates an inlet pipe pressure gauge, an inlet pipe pressure transmitter, and an inlet pipe flow meter at its outlet end. This enables full-parameter monitoring of the carrier air terminal output pressure, real-time pressure feedback, and actual flow rate. The pressure gauge can intuitively display the terminal pressure, facilitating on-site inspection. The pressure transmitter converts the pressure signal into an electrical signal and transmits it to the auxiliary components, providing data for remote control. The flow meter monitors the air supply in real time and can promptly detect abnormal air volume (such as a sudden drop in flow rate caused by pipeline blockage).

[0014] The full-process monitoring design overcomes the shortcomings of the single carrier air system monitoring in the existing technology, realizing dynamic tracking of the carrier air supply status. Operators can monitor parameter changes in real time through local or remote terminals, predict potential faults in advance (such as abnormal pressure fluctuations or insufficient flow), and take timely control measures to reduce the risk of system downtime caused by abnormal carrier air parameters.

[0015] In this embodiment, the bypass design of the intake pipe assembly can be activated during main pipeline maintenance or pressure fluctuations to assist in adjusting pressure stability, further ensuring the continuity of carrier air supply and reducing the risk of system downtime. On the one hand, during maintenance or repair of the main pipeline (from the first pressure reducing valve to the second pressure reducing valve section), the third intake air valve can be opened to continuously supply carrier air to the second pressure reducing valve via the bypass, avoiding system downtime, ensuring continuous operation of the plasma ignition system, and improving maintenance convenience. On the other hand, when the main pipeline pressure fluctuates slightly, the opening of the third intake air valve can be adjusted to divert or supplement some carrier air to the inlet of the second pressure reducing valve, helping to stabilize the inlet pressure and further improving the stability of the terminal pressure output.

[0016] The bypass design breaks through the limitations of the traditional single-path carrier air duct, which not only solves the contradiction between maintenance and continuous operation, but also enhances the flexibility of pressure regulation, so that the air inlet pipe assembly can be adapted to the carrier air supply needs under different working conditions (such as normal operation, maintenance and repair, and pressure fluctuation adjustment), thereby improving the overall applicability of the device.

[0017] In addition, the first, second, and third inlet ball valves in this solution realize the start-up and shutdown of the main pipeline, the segmented on / off and bypass control, respectively. The pipeline on / off state can be flexibly switched according to actual needs, which facilitates the individual maintenance of single components (such as proportional pressure valves and needle valves) without having to shut down the entire inlet pipe assembly, thus reducing operation and maintenance costs. At the same time, the ball valve has a simple structure and good sealing performance, which can reduce the risk of carrier air leakage.

[0018] The proportional pressure valve supports remote control via PLC. With the signal feedback from the pressure transmitter, a monitoring-control closed loop is formed. Operators do not need to manually adjust the valve on-site. They only need to set the target parameters in the control room to achieve automatic pressure regulation. This not only improves the ease of operation but also avoids the safety risks of on-site operation, making it suitable for the centralized control needs of industrial scenarios.

[0019] Furthermore, a needle valve is installed between the outlet end of the proportional pressure valve and the inlet end of the second pressure reducing valve.

[0020] Beneficial effects: The needle valve in this solution further refines the accuracy of flow and pressure regulation, making up for the shortcomings of traditional regulating valves in terms of coarse regulation.

[0021] Furthermore, the carrier air is compressed air or nitrogen.

[0022] Beneficial effects: Compressed air is the most readily available air source in industrial scenarios and is widely used in various factories, power plants and other application environments. Choosing compressed air as the carrier air can directly utilize the existing air source system on site without the need for additional dedicated air supply equipment, which reduces the deployment cost and usage threshold of the device. Nitrogen possesses the characteristics of an inert gas (chemically stable, non-flammable and non-explosive). Under special working conditions such as high temperature and flammable and explosive conditions (e.g., gas boiler ignition, chemical raw material ignition scenarios), it can prevent the carrier air from reacting with the flammable medium in the ignition environment, reduce safety risks, and enable the device to adapt to both conventional and special hazardous working conditions, significantly broadening its application range.

[0023] The dual-source design allows users to switch flexibly according to actual needs, satisfying both economic requirements under normal operating conditions and safety requirements under special operating conditions, thereby enhancing the market applicability and competitiveness of the device.

[0024] Furthermore, the water inlet pipe assembly is a pipeline assembly for conveying cooling water to the plasma igniter. The water inlet pipe assembly includes a cooling water pipeline and control elements and monitoring elements connected to the cooling water pipeline. The control elements include a first water inlet pipe ball valve connected to the cooling water pipeline. The monitoring elements include a water inlet pipe pressure gauge, a water inlet pipe pressure transmitter, and a water inlet pipe thermometer connected in sequence to the outlet end of the first water inlet pipe ball valve. One end of the cooling water pipeline is divided into two paths, namely a cathode water inlet pipe and an anode water inlet pipe. Both the cathode water inlet pipe and the anode water inlet pipe are equipped with water inlet pipe flow meters.

[0025] Beneficial effects: In this solution, the cooling water pipeline is designed with separate inlet pipes for the cathode and anode, enabling independent water supply to the anode and cathode of the plasma igniter. This solves the problem that traditional cooling systems with single-channel water supply cannot accurately match the different cooling needs of the anode and cathode. This solution can allocate appropriate flow rates according to the differences in heat generation power and heat loss of the anode and cathode through subsequent regulation (such as valve fine-tuning), ensuring that both are in the best cooling state, avoiding igniter burnout due to insufficient local cooling or energy waste caused by excessive cooling.

[0026] The independent branch structure ensures that the cooling water supply to the anode and cathode does not interfere with each other. Even if a slight abnormality occurs in one branch (such as flow fluctuation), it will not directly affect the cooling effect of the other branch, thus improving the cooling system's fault resistance and ensuring the operational stability of the plasma igniter.

[0027] In this solution, the outlet end of the ball valve on the first inlet pipe is sequentially equipped with an inlet pipe pressure gauge, an inlet pipe pressure transmitter, and an inlet pipe thermometer. This enables full-parameter monitoring of the cooling water inlet pressure, pressure signal feedback, and water supply temperature. The pressure gauge displays the inlet pressure directly, facilitating on-site inspection. The pressure transmitter transmits the pressure signal to auxiliary components, providing data support for remote control. The inlet pipe thermometer monitors the initial water supply temperature in real time, preventing excessively high inlet water temperatures from affecting the cooling effect.

[0028] The cathode and anode water inlet pipes are each equipped with a water inlet pipe flow meter to enable separate monitoring of the cooling water volume of the cathode and anode. Compared with the shortcomings of traditional cooling systems that cannot distinguish the flow of the cathode and anode, this design can accurately detect single-path flow anomalies (such as a sudden drop in flow caused by pipe blockage or flow loss caused by leakage), and provide timely warning of the risk of local cooling failure, so as to avoid shortened igniter life or malfunction shutdown caused by uneven cooling of the cathode and anode.

[0029] The first inlet ball valve serves as the core control element, enabling rapid on / off control of the cooling water pipeline, facilitating system start-up and shutdown operations and pipeline maintenance. The monitoring element and auxiliary components form a collaborative closed loop. Signals from the inlet pressure transmitter, thermometer, and flow meter are fed back to the auxiliary components in real time. If situations arise such as pressure falling below the threshold, inlet water temperature exceeding the standard, or abnormal flow in a branch, the auxiliary components can be linked to control the situation, preventing the anomaly from escalating. This eliminates the need for manual on-site troubleshooting, reducing maintenance workload and fault handling time.

[0030] Furthermore, the return water pipe assembly is a pipeline assembly for recovering the cooling water after heat exchange of the plasma igniter. The return water pipe assembly includes a cathode return water pipe and an anode return water pipe that are respectively connected to the cathode and anode of the plasma igniter. The outlet ends of the cathode return water pipe and the cathode return water pipe merge into a return water branch. Monitoring elements are installed on both the cathode return water pipe and the anode return water pipe. The monitoring elements include a loop flow meter and a loop thermometer. A control element is installed on the return water branch. The control element includes a first loop ball valve installed at the outlet end of the cathode return water pipe and the anode return water pipe.

[0031] Beneficial effects: The separate design of the cathode and anode return water pipes corresponding to the inlet pipe components continues the independent monitoring logic of the anode and cathode. By installing loop flow meters and loop thermometers on the two return water pipes respectively, the flow rate and temperature data of the cooling water after heat exchange between the anode and cathode can be collected independently. The two return water pipes merge into a single return water branch, realizing centralized recycling of cooling water, avoiding the pipe clutter and energy waste caused by separate return flows, while simplifying the overall layout of the return water system. This aligns with the integrated design concept of the inlet pipe components and further enhances the modularity of the entire air-water skid-mounted unit.

[0032] Furthermore, an ambient temperature and humidity sensor for detecting ambient temperature and humidity is installed on the base.

[0033] Beneficial effects: The ambient temperature and humidity sensor installed on the base in this solution is beneficial for real-time monitoring of the temperature and humidity in the area, ensuring the stable operation of the plasma ignition system.

[0034] Furthermore, both sides of the base are connected to lifting lugs.

[0035] Beneficial effects: The modular integrated design allows each component to be pre-installed and debugged before leaving the factory. On-site installation can be quickly achieved by simply using the lifting lugs on the base, avoiding the complex procedures of scattered installation and pipeline connection of traditional split equipment. This reduces installation difficulty and labor costs, while also reducing the problem of messy on-site wiring and improving the neatness of equipment layout.

[0036] Furthermore, the auxiliary component includes a junction box, which is used to centrally connect the signal lines of each monitoring element and control element in the air intake pipe assembly, the return water pipe assembly, and the water inlet pipe assembly, so as to realize signal transfer and centralized management.

[0037] Beneficial effects: In this solution, auxiliary components are centrally connected to the monitoring and control signal lines of each component through a junction box, achieving unified signal transfer and centralized management. This breaks through the limitations of existing technologies where the carrier air system and cooling system are separately controlled and cannot be linked. It can monitor the pressure, temperature, flow rate, and ambient temperature and humidity parameters of the entire device in real time, providing comprehensive data support for control decisions. Furthermore, the centralized wiring design avoids the problems of messy on-site wiring and numerous interfaces in traditional split-type equipment, reduces the risk of signal line cross-interference, and improves the stability and accuracy of signal transmission. In particular, it ensures the signal accuracy of precision components such as pressure transmitters and flow meters, providing reliable data support for precise control.

[0038] As a signal transfer hub, the junction box enables centralized transmission of monitoring signals and control commands. Data such as pressure, flow, and temperature collected by the monitoring elements are uniformly transmitted to the existing PLC controller through the junction box. Control commands are then accurately distributed to the corresponding control elements (such as proportional pressure valves and ball valves) through the junction box, forming a centralized control closed loop of data acquisition and command issuance.

[0039] Operators no longer need to operate each pipeline component on-site. They can monitor and control the parameters of the entire system (such as adjusting the carrier air pressure, switching on and off the cooling water pipeline, and checking the operating status of each branch) through the remote terminal in the control room. This greatly reduces the labor intensity and safety risks of on-site operation, adapts to the centralized control needs of industrial scenarios, and improves the convenience and efficiency of operation.

[0040] Furthermore, the base is provided with a support frame, and there are two sets of support frames, namely a first support frame and a second support frame. The two sets of support frames are arranged side by side. The air intake pipe assembly is fixed on the first support frame, and the water return pipe assembly and the water intake pipe assembly are fixed on the second support frame, with the water return pipe assembly located below the water intake pipe assembly.

[0041] Beneficial effects: In this design, the support frame is used to support and fix the air intake pipe assembly, water return pipe assembly, and water inlet pipe assembly, allowing the three components to be neatly and compactly integrated on the base. Furthermore, the two sets of support frames arranged side-by-side, combined with the layered layout of the second support frame, allow for the orderly accommodation of the three major pipeline components (air intake, water inlet, and water return) within the limited footprint of the base. Compared to the traditional split-type equipment that occupies a dispersed space, this further reduces the overall volume, making it particularly suitable for installation scenarios with limited space, such as factories and power plants, thus improving the spatial adaptability of the device.

[0042] Furthermore, in this design, the return water pipe assembly is located below the inlet water pipe assembly, which is beneficial for the return water of the plasma igniter, while the inlet water pipe assembly is located on the upper layer, making installation more convenient.

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0046] As one embodiment of this application, such as Figures 1-2As shown, this embodiment provides an integrated gas-water skid-mounted device for a plasma ignition system, including a base 4, an air inlet pipe assembly 1, a water return pipe assembly 2, a water inlet pipe assembly 3 integrated and installed on the base 4, and auxiliary components for realizing intelligent control and monitoring. The air inlet pipe assembly 1, the water return pipe assembly 2, and the water inlet pipe assembly 3 all include monitoring elements for monitoring the internal temperature and / or flow rate and / or pressure of the pipe, as well as control elements for controlling the on / off of the pipe and / or for regulating the pressure of the pipe. Auxiliary components are used to monitor and regulate the operating parameters of the entire device.

[0047] like Figure 1 As shown, in this embodiment, a support frame is provided on the base 4. There are two sets of support frames, namely the first support frame 7 and the second support frame 8. The two sets of support frames are arranged side by side. The air intake pipe assembly 1 is fixed on the first support frame 7, and the water return pipe assembly 2 and the water intake pipe assembly 3 are fixed on the second support frame 8. The water return pipe assembly 2 is located below the water intake pipe assembly 3.

[0048] In one embodiment, such as Figure 1 As shown, in this embodiment, the support frame is equipped with multiple clamps 9 for fixing the pipes in the air intake pipe assembly 1, the return water pipe assembly 2, and the water intake pipe assembly 3. The pipes are fixed to the support frame by the clamps 9 and bolts, thereby realizing the installation of the three components. The clamp 9 is a split structure, consisting of an upper clamp and a lower clamp. The pipe passes through the lower clamp, and then the upper clamp is fastened to the lower clamp. The upper and lower clamps are then fixed by bolts to secure the pipe.

[0049] In one embodiment, such as Figure 1 As shown, in this embodiment, lifting lugs 400 are connected to both sides of the base 4. In this embodiment, four lifting lugs 400 are provided, with two of the four lifting lugs 400 forming a group, and the two groups of lifting lugs 400 are located on both sides of the base 4 respectively. The lifting lugs 400 facilitate the hoisting of the base 4, thereby hoisting the air intake pipe assembly 1, water return pipe assembly 2, and water inlet pipe assembly 3 integrated on the base 4 to the designated position.

[0050] In addition, in this embodiment, two bolt mounting holes 410 are provided on each side of the base 4. The bolt mounting holes 410 are provided so that after the base 4 is hoisted to the designated position, the base 4 can be fixed with bolts, thereby ensuring the stability of the entire device.

[0051] In one embodiment, combined Figure 1 and Figure 3As shown, in this embodiment, the intake pipe assembly 1 is an intake pipe for conveying carrier air, including monitoring elements installed on the intake pipe. These monitoring elements include a first intake balloon valve 100, a first pressure reducing valve 110, a second intake balloon valve 101, a proportional pressure valve 120, a needle valve 130, and a second pressure reducing valve 111, all sequentially installed on the intake pipe. Control elements are also installed on the intake pipe, including an intake pipe pressure gauge 140, an intake pipe pressure transmitter 150, and an intake pipe flow meter 160, all installed at the outlet end of the second pressure reducing valve 111. A bypass branch is also branched off at the outlet end of the first pressure reducing valve 110, connected to a third intake balloon valve 102, with one end of the bypass returning to the inlet end of the second pressure reducing valve 111. In this embodiment, the needle valve 130 installed between the outlet end of the proportional pressure valve 120 and the inlet end of the second pressure reducing valve 111 further refines the flow and pressure regulation accuracy, overcoming the shortcomings of traditional regulating valves in terms of coarse regulation.

[0052] In this embodiment, the first pressure reducing valve 110 in the intake pipe assembly 1 is used to initially reduce the pressure of the carrier air input from the front end. The proportional pressure valve 120 is controlled by an auxiliary component to precisely adjust the outlet pressure. The needle valve 130 is used to finely regulate the flow rate or pressure of the carrier air passing through the proportional pressure valve 120. The second pressure reducing valve 111 is used to further stabilize and adjust the inlet pressure to a pressure value suitable for the operation of the plasma igniter before delivering it to the plasma igniter. In this embodiment, the carrier air delivered is compressed air or nitrogen.

[0053] In one embodiment, such as Figure 1 and Figure 3 As shown, the water inlet pipe assembly 3 is a pipeline assembly used to transport cooling water to the plasma igniter. The water inlet pipe assembly 3 includes a cooling water pipeline and control elements and monitoring elements connected to the cooling water pipeline. The control elements include a first water inlet pipe ball valve 320 connected to the cooling water pipeline. The monitoring elements include a water inlet pipe pressure gauge 340, a water inlet pipe pressure transmitter 350, and a water inlet pipe thermometer 360 connected in sequence to the outlet end of the first water inlet pipe ball valve 320. One end of the cooling water pipeline is divided into two paths, namely a cathode water inlet pipe 300 and an anode water inlet pipe 310. A water inlet pipe flow meter 370 is installed on both the cathode water inlet pipe 300 and the anode water inlet pipe 310. In this embodiment, a second water inlet pipe ball valve 330 is also installed on the cathode water inlet pipe 300.

[0054] In one embodiment, such as Figure 1 and Figure 3 As shown, the return water pipe assembly 2 is a pipeline assembly used to recover the cooling water after heat exchange of the plasma igniter. The return water pipe assembly 2 includes a cathode return water pipe 200 and an anode return water pipe 210, which are respectively connected to the cathode and anode of the plasma igniter. The outlet ends of the cathode return water pipe 200 and the cathode return water pipe 210 merge into a return water branch. Monitoring elements are installed on both the cathode return water pipe 200 and the anode return water pipe 210. The monitoring elements include a loop flow meter 220 and a loop thermometer 230. A control element is installed on the return water branch. The control element includes a first loop ball valve 250 installed at the outlet end of the cathode return water pipe 200 and the anode return water pipe 210. In this embodiment, a second loop ball valve 240 is installed on the cathode return water pipe 200 near its outlet end.

[0055] In one embodiment, combined Figure 1 As shown, an ambient temperature and humidity sensor 6 for detecting ambient temperature and humidity is installed on the base 4. In this embodiment, a bracket 610 is vertically fixed to the base 4 by bolts, and the ambient temperature and humidity sensor 6 is installed on the top of the bracket 610. The ambient temperature and humidity sensor 6 is an integrated component that combines a temperature sensor and a humidity sensor.

[0056] In one embodiment, the pipes in the return water pipe assembly 2, the inlet water pipe assembly 3, and the air inlet pipe assembly 1 are all made of 304 stainless steel, which has high overall strength and corrosion resistance.

[0057] In one embodiment, such as Figure 1 As shown, the auxiliary components include a junction box 5, which is mounted on the base 4. The junction box 5 is used to centrally connect the signal lines of each monitoring element and control element in the air intake pipe assembly 1, the return water pipe assembly 2, and the water intake pipe assembly 3, so as to realize signal transfer and centralized management.

[0058] Junction box 5 needs to be connected to signal source equipment, remote control terminal (such as PLC controller), etc. The PLC controller receives the monitoring signals relayed by junction box 5, such as pressure, flow and temperature data, for system status judgment (such as whether there is overpressure or whether the flow rate meets the standard). The PLC controller outputs control commands to the junction box 5, such as adjusting the opening of the proportional pressure valve 120 and controlling the switch of the electric valve. The commands are then transferred to the corresponding actuators via the junction box 5.

[0059] This utility model adopts a modular design to integrate carrier gas supply (such as nitrogen and compressed air), water cooling circulation and pressure regulation functions. The entire skid-mounted device has a reasonable and neat layout, and its volume is reduced by 200% compared with the traditional split system. It is easy to install and can be disassembled as a whole.

[0060] Furthermore, by incorporating multi-stage pressure regulation devices and intelligent temperature and humidity control, the plasma ignition system ensures its intelligence and stability, reducing the need for manual on-site valve operation. Operation can be performed solely from the control room.

[0061] This invention features distributed monitoring points for the anode and cathode water inlet and outlet, enabling real-time monitoring of their operating status and improving the safety and operational stability of the plasma ignition system.

[0062] In this embodiment, the intake pipe assembly 1 incorporates multi-stage pressure regulation and control elements (such as pressure reducing valve, proportional pressure valve 120, needle valve 130) and pressure and flow monitoring elements. Through precise regulation, it achieves stable output of carrier air pressure, effectively solving the problem of insufficient air supply caused by pressure reduction of pneumatic shut-off valve in the prior art. This ensures that the plasma ignition system obtains a continuous and sufficient supply of carrier air, avoids power limitation due to air shortage, and improves ignition efficiency and stability. The inlet pipe assembly 3 and the return pipe assembly 2 are equipped with independent pipes for the anode and cathode of the plasma igniter, and are equipped with temperature, pressure and flow monitoring elements to realize individual and real-time monitoring of key parameters of the anode and cathode cooling system. This solves the defect of existing technology that cannot accurately capture local cooling anomalies, and can detect problems such as pipe blockage, insufficient flow and excessive temperature in time, so as to avoid igniter burnout due to cooling failure. The coordinated operation of monitoring and control components forms a closed-loop control system, which can adjust the control strategy in real time according to changes in operating parameters (such as automatically adjusting the opening of the proportional pressure valve to 120 degrees when pressure fluctuates), avoiding abnormal expansion of parameters, significantly improving the overall operational stability and reliability of the plasma ignition system, and reducing maintenance costs and failure rate.

[0063] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
