Description

Technical Field

[0001] This invention relates to the field of metal powder metallurgy preparation and industrial gas recovery energy efficiency management technology, and particularly to an argon recovery energy efficiency management method and intelligent system in the titanium powder manufacturing process. Background Technology

[0002] Electrode induction melting gas atomization is a common method for producing metal powders such as titanium powder. This production process requires a large amount of high-purity argon gas as a protective atmosphere and atomizing medium. To save production costs and achieve gas recycling, industrial sites typically have closed-loop argon recovery networks. In the exhaust gas recovery and recycling process, multi-stage pressurization equipment releases waste heat by pressurizing the fluid. The liquid argon vaporization module at the source needs to continuously absorb the latent heat of phase change when converting liquid argon into gaseous argon, and the purification equipment on the main pipeline also needs to maintain a specific high-temperature operating environment for catalytic deoxygenation and dehydration. Using a closed-loop cooling water network to collect the waste heat released during the compression process and directionally transport it to the aforementioned heat-using nodes for heat reuse is a commonly adopted energy efficiency management solution in the industry.

[0003] In actual continuous pulverization operations, the gas atomization equipment experiences fluctuating gas loads due to variations in process cycle time. When the overall gas pressure in the pipeline drops, the liquid argon vaporization module must immediately increase the evaporation rate of gaseous argon to compensate for the pressure gap, causing a sudden surge in cooling load at the front-end heat exchange interface. The heat transfer of cooling fluid within the physical pipeline is limited by spatial distance and flow velocity; the delivery of wastewater hot water from the compressor's heating end to the vaporization module inevitably faces a transmission lag. This physical time delay means that heat replenishment cannot be perfectly synchronized with the sudden vaporization cooling load. If, during the water flow lag, the heat medium intended for the purifier is urgently diverted to the vaporization module for emergency use, the deoxygenation and dehydration bed inside the purifier faces the risk of heat source interruption and environmental cooling. Industrial impurity removal materials require a set temperature threshold to exert normal catalytic activity; any temperature drop directly affects the purity of the final recovered gas and the stability of system operation. Summary of the Invention

[0004] The purpose of this invention is to provide an argon recovery energy efficiency control method and intelligent system for titanium powder manufacturing process, in order to solve the technical problems in the prior art where the waste heat cannot be timely compensated for the surge in cooling load at the front end due to the transmission delay in the long-distance transportation of cooling fluid, and the subsequent purification module is prone to inaccurate cooling when local emergency heat energy is transferred.

[0005] In a first aspect, the present invention provides an argon gas recovery energy efficiency control method for the titanium powder manufacturing process, applied to an intelligent system, wherein the intelligent system is connected to a liquid argon vaporization module, an argon gas blower, a medium-pressure compressor, a purifier, a high-pressure compressor, a heater, and an electrode induction melting gas atomization device; the control method includes: Liquid argon is controlled to enter the liquid argon vaporization module to absorb heat and transform into gaseous argon. The gaseous argon is mixed with the recovered argon and then processed by the medium-pressure machine, the purifier, the high-pressure machine and the heater before being sent to the electrode induction melting gas atomization device; The exhaust gas discharged from the electrode induction melting gas atomization device is controlled to be drawn by the argon blower to form the recovered argon gas; The cooling water of the dispatching system absorbs the waste heat discharged from the argon blower, the medium-pressure machine and the high-pressure machine, and transports the waste heat to the liquid argon vaporization module, the purifier and the heater for heat reuse; The control method also includes: Real-time extraction of the dynamic gas pressure drop slope generated during the operation of the electrode-induction melting gas atomization device; When the slope of the dynamic gas pressure drop exceeds the set alarm limit, the fluid transport lag time window faced by the system cooling water in transporting the waste heat of the intermediate compressor to the liquid argon vaporization module is calculated. Within the fluid transport hysteresis time window, an internal airflow swirl command is sent to the intermediate compressor to control the intermediate compressor to generate transient compensation heat energy by gas compression and friction self-excitation; The waste heat that was originally intended to be delivered to the purifier is urgently diverted to the liquid argon vaporization module to compensate for the surge in cooling load caused by vaporization; The transient compensation thermal energy is transferred to the purifier nearby to maintain the set temperature threshold required for impurity removal.

[0006] Optionally, the step of the dispatching system absorbing the waste heat discharged from the argon blower, the medium-pressure compressor, and the high-pressure compressor by cooling water, and then transferring the waste heat to the liquid argon vaporization module, the purifier, and the heater for heat reuse includes: The initial cooling water is driven by a cooling water pump to flow through the argon gas blower, the medium-pressure machine, and the peripheral heat exchange jacket of the high-pressure machine; The high-temperature heat emitted by the gas during the extraction and compression stages is absorbed, and the initial cooling water is converted into a heated cooling water. The heated cooling water is channeled through pipes to the evaporation and heat absorption end of the liquid argon vaporization module, the heat preservation end of the purifier, and the bottom preheating interface of the heater.

[0007] Optionally, the step of controlling liquid argon to enter the liquid argon vaporization module to absorb heat and transform into gaseous argon includes: Monitor the real-time operating gas pressure value inside the main gas supply pipeline connected to the liquid argon vaporization module; Determine whether the real-time operating air pressure value is lower than the lower limit of safe production; When the real-time operating gas pressure value is determined to be lower than the lower limit of safe production, the liquid argon input valve of the liquid argon vaporization module is opened; The latent heat of vaporization is provided by the cooling water flowing into the evaporation end, and the generated gaseous argon is transported to the inside of the main gas supply pipeline.

[0008] Optionally, the step of controlling the mixing of gaseous argon with recovered argon gas, followed by processing through the medium-pressure press, the purifier, the high-pressure press, and the heater, before being fed into the electrode induction melting gas atomization device includes: Monitor the oxygen and moisture content parameters of the gas processed inside the purifier; If the oxygen content parameter or the moisture content parameter deviates from the preset impurity removal qualification line, the electric regulating valve of the water circuit is controlled to increase the opening degree, so as to increase the flow rate of the heated cooling water flowing into the heat preservation end, thereby improving the catalytic impurity removal efficiency. The purified gas is controlled to enter the high-pressure machine for secondary pressurization; The gas after secondary pressurization is controlled to enter the heater, and the temperature is raised to the set operating temperature by the auxiliary heating wire installed inside the heater.

[0009] Optionally, the step of controlling the exhaust gas discharged from the electrode induction melting gas atomization device to be drawn by the argon blower to form the recovered argon gas includes: A dust filter screen is installed at the end of the exhaust channel of the electrode induction melting gas atomization device; The negative pressure suction force of the argon gas fan is used to draw the exhaust gas containing metal dust to the dust filter screen for solid-gas separation. The purified gas after the dust has been separated is sent into the inlet of the medium-pressure machine as the recovered argon gas.

[0010] Optionally, the step of calculating the fluid transport hysteresis time window encountered by the system cooling water in transporting the waste heat from the intermediate compressor to the liquid argon vaporization module includes: Read the total length of the physical pipeline in space between the heat exchange port of the intermediate pressure machine and the heat exchange port of the liquid argon vaporization module; Obtain the current delivery speed of the system cooling water in the main pipeline; Divide the total length of the space physical pipeline by the current delivery speed to obtain the basic physical transmission time. By introducing the thermal conductivity hysteresis coefficient of the equipment housing to correct and extend the basic physical transmission time, the fluid transmission hysteresis time window is obtained.

[0011] Optionally, the step of issuing an internal airflow swirl command to the intermediate compressor to control the intermediate compressor to generate transient compensation heat energy through gas compression and frictional self-excitation includes: Calculate the total amount of heat energy loss faced by the purifier due to the emergency diversion of the waste heat; While maintaining the gas flow rate output from the intermediate compressor to the purifier, increase the operating frequency of the intermediate compressor. The bypass return channel inside the medium-pressure unit is opened simultaneously, allowing the additional gas drawn in to circulate at a high frequency between the internal cylinder and the bypass return channel. By utilizing the intermolecular shear forces and aerodynamic friction forces on the tube wall caused by high-frequency reciprocating cycles, the additional mechanical work is converted into transient compensating thermal energy that matches the total amount of thermal energy loss.

[0012] Optionally, the step of transferring the transient compensation thermal energy to the purifier nearby to maintain the set temperature threshold required for impurity removal includes: Monitor the real-time temperature slope of the catalytic bed inside the purifier; The generation rate of transient compensation heat energy is dynamically controlled by adjusting the throttling opening of the bypass return channel. The generated transient compensating thermal energy is directionally conducted to the catalytic bed through a local short heat conduction pipe.

[0013] Optionally, the control method further includes a smooth recovery step after the fluid transport hysteresis time window ends: Start a time accumulation counter and continuously track and record the length of time consumed; When the time consumed reaches the boundary node of the fluid transport hysteresis time window, it is determined that the waste heat discharged by the intermediate compressor has arrived at the heat distribution hub along with the system cooling water. Immediately cancel the emergency diversion action of the waste heat to the liquid argon vaporization module and restore the normal waste heat distribution ratio; The internal airflow swirl command is terminated simultaneously, causing the medium-pressure compressor to return to the standard power consumption operating mode.

[0014] Secondly, the present invention provides an intelligent system for energy efficiency control of argon recovery in titanium powder manufacturing process. The intelligent system is equipped with a processor and a computer-readable storage medium, and the computer-readable storage medium contains an executable logic code sequence. When the processor calls and runs the executable logic code sequence, it implements all the control steps covered by the argon recovery energy efficiency control method for titanium powder manufacturing process described in any one of the first aspects.

[0015] The present invention has achieved the following beneficial effects: This invention, by extracting the slope of the dynamic gas pressure drop in the electrode sensing molten gas atomization device, can calculate the fluid transport lag time window encountered when the gas supply pressure fluctuates, specifically the time required for the compressor waste heat to be transported to the liquid argon vaporization module. During the gap period when cooling water cannot arrive immediately due to the time required for physical transport, the control system urgently redirects the waste heat originally destined for the purifier to the liquid argon vaporization module, promptly filling the latent heat gap caused by the surge in the vaporization process. Simultaneously, the system issues an internal airflow swirl command to the intermediate compressor, utilizing the internal compression and aerodynamic friction of the return gas to generate compensating heat energy locally, and transfers this heat to the purifier nearby, compensating for the heat energy loss faced by the purifier due to the temporary allocation of waste heat. This thermal scheduling method overcomes the time misalignment obstacle of long-distance transmission of the heat medium in the spatial pipeline, ensuring the underlying process heat demand of each related module while smoothing out pressure fluctuations in the main gas supply network, avoiding the risk of impurity removal and deoxygenation cooling caused by emergency local heat energy transfer, and achieving closed-loop thermal balance in the multi-node dynamic flow process of the argon recovery system.

Detailed Implementation

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] This embodiment discloses a method and intelligent system for controlling the energy efficiency of argon gas recovery in the titanium powder manufacturing process. For example... Figure 1 As shown, the intelligent system connects a liquid argon vaporization module, an argon blower, a medium-pressure compressor, a purifier, a high-pressure compressor, a heater, and an electrode induction melting gas atomization device. The physical modules are sequentially connected in spatial layout, forming a closed-loop material circulation system through a pressurized metal pipe network and a heat exchange and balance circulation system through a closed-loop cooling water pipe network. The liquid argon vaporization module is located at the source of the gas supply physical topology, and its output interface is connected to the main gas supply pipeline. The medium-pressure compressor, the purifier, the high-pressure compressor, and the heater are sequentially connected in series on the main pressurization and purification branches. The heater's end interface is directly connected to the main inlet control valve of the electrode induction melting gas atomization device. The negative pressure suction port of the argon blower is connected to the exhaust chamber of the electrode induction melting gas atomization device, and the positive pressure exhaust port of the argon blower is connected to the inlet node of the medium-pressure compressor. The main body of the intelligent system integrates a processor and a programmable logic circuit board, and communicates bidirectionally with the actuation mechanism of the aforementioned fluid module and the sensor array distributed at the pipeline nodes through a field-isolated communication bus.

[0021] Specifically, the energy efficiency control method for argon gas recovery in the titanium powder manufacturing process is applied to the aforementioned intelligent system, such as... Figure 2 As shown, the control method includes the following steps: Step S10: Control the liquid argon to enter the liquid argon vaporization module to absorb heat and transform into gaseous argon; Step S20: After the gaseous argon is mixed with the recovered argon, it is processed by the medium-pressure machine, the purifier, the high-pressure machine and the heater, and then sent to the electrode induction melting gas atomization device; Step S30: Control the tail gas discharged from the electrode induction melting gas atomization device to be drawn by the argon blower to form the recovered argon gas; Step S40: The system cooling water absorbs the waste heat discharged by the argon blower, the medium-pressure machine and the high-pressure machine, and transports the waste heat to the liquid argon vaporization module, the purifier and the heater for heat reuse; Step S50: Extract the dynamic gas pressure drop slope generated during the operation of the electrode induction melting gas atomization device in real time; Step S60: When the slope of the dynamic gas pressure drop exceeds the set alarm limit, calculate the fluid transport lag time window faced by the system cooling water in transporting the waste heat of the intermediate compressor to the liquid argon vaporization module; Step S70: Within the fluid transport hysteresis time window, an internal airflow swirl command is sent to the intermediate compressor to control the intermediate compressor to generate transient compensation heat energy by utilizing gas compression and friction self-excitation; Step S80: The waste heat that was originally intended to be delivered to the purifier is urgently diverted to the liquid argon vaporization module to compensate for the surge in cooling load caused by vaporization; Step S90: The transient compensation thermal energy is transferred to the purifier nearby to maintain the set temperature threshold required for impurity removal, thereby effectively eliminating the global thermal imbalance caused by pipeline transmission delay.

[0022] Furthermore, regarding step S40, such as Figure 3 As shown, the process of the scheduling system absorbing waste heat from the argon gas blower, the intermediate-pressure compressor, and the high-pressure compressor, and then transferring this waste heat to the liquid argon vaporization module, the purifier, and the heater for heat reuse includes: driving initial-state cooling water through the heat exchange jackets of the argon gas blower, the intermediate-pressure compressor, and the high-pressure compressor via a cooling water pump; absorbing the high-temperature heat emitted by the gas during extraction and compression, converting the initial-state cooling water into heated cooling water; and using pipelines to guide the heated cooling water to the evaporation heat absorption end of the liquid argon vaporization module, the insulation end of the purifier, and the bottom preheating interface of the heater. It is understood that when the compressor performs volumetric compression, the enthalpy of the gas increases, transferring sensible heat to the outer equipment housing. The cooling water pump provides a constant circulating head, forcing the water medium to flow through the outer heat exchange jackets. A convective heat transfer process occurs between the water and the equipment housing, with the water medium carrying away waste heat and forming the heated cooling water. Electric proportional three-way regulating valves distributed at multiple branch nodes control the flow of cooling water during the heating state, thus constructing a heat transfer hardware channel within the system.

[0023] Furthermore, regarding step S10, such as Figure 4As shown, the step of controlling liquid argon to enter the liquid argon vaporization module to absorb heat and transform into gaseous argon includes: monitoring the real-time operating gas pressure value inside the main gas supply pipeline connected to the liquid argon vaporization module; determining whether the real-time operating gas pressure value is lower than the safety production lower limit; when it is determined that the real-time operating gas pressure value is lower than the safety production lower limit, opening the liquid argon input valve of the liquid argon vaporization module; and using the heating state cooling water flowing into the evaporation heat absorption end to provide the latent heat of vaporization, transporting the generated gaseous argon to the inside of the main gas supply pipeline.

[0024] The underlying data acquisition link of the intelligent system is connected to an absolute pressure piezoresistive transmitter. The pressure-sensing diaphragm of the piezoresistive transmitter undergoes physical deformation under pressure, generating a corresponding differential analog level signal. The analog input channel samples and quantizes the differential analog level signal. During periodic acquisition, the processor uses a digital filtering algorithm to process discrete sampling points, generating a stable real-time operating pressure value. The microprocessor's arithmetic logic module compares the real-time operating pressure value with the safety production lower limit stored in a non-volatile block. When the comparison result indicates that the pressure parameter is lower than the calibrated threshold, the program thread activates the output channel. The digital-to-analog conversion module outputs a continuous analog current signal to the servo positioner of the liquid argon input valve. The servo positioner drives the valve stem to generate linear mechanical displacement, setting the valve's flow cross-sectional area. Liquid argon flows into the heat exchange pipeline inside the liquid argon vaporization module. Simultaneously, the heated cooling water flowing into the outer shell space transfers heat flux to the inner wall of the pipeline. The liquid argon medium absorbs the latent heat of phase change and undergoes a boiling physical transformation, turning into room temperature gas molecules and being forced into the main gas supply pipeline to maintain macroscopic aerodynamic pressure.

[0025] Specifically, for the aforementioned digital filtering algorithm, to reduce computational complexity, this system preferably adopts an industrial-grade first-order inertial hysteresis filtering formula. Its discrete difference equation, embedded within the microprocessor, is as follows: .in, For the first The smoothed output value of each discrete sampling period; For the first The original digital sampled values ​​of the barometric modulus conversion obtained in each cycle; For the first The smoothed output value for each cycle; This is the filtering time constant factor; This represents the discrete sampling period number, which is a positive integer. Based on the high-frequency gas pulse characteristics caused by the rotation of the high-power argon fan impeller, in this embodiment... Setting the threshold between 0.15 and 0.25, the system can effectively filter out sensor resonance glitches using simple algebraic iterations at the lower level, saving computational resources. The aforementioned lower limit for safe production is derived based on the critical point in fluid mechanics. .in, This represents the minimum safe operating limit within the main gas supply pipeline. To maintain the critical back pressure required for the Laval nozzle in the end electrode induction molten gas atomization device to establish a supersonic airflow in order to effectively overcome high surface tension and pulverize titanium droplets; This represents the sum of the maximum pressure drop along the main gas supply line and the local pressure drop. For typical medium-sized titanium alloy powder preparation conditions, this safe production lower limit is precisely quantified and set at 3.5 MPa (absolute pressure).

[0026] Furthermore, regarding step S20, such as Figure 5 As shown, the step of controlling the mixing of gaseous argon and recovered argon, followed by processing through the medium-pressure press, the purifier, the high-pressure press, and the heater, before being fed into the electrode induction melting gas atomization device includes: monitoring the oxygen content and moisture content parameters of the gas processed inside the purifier; if the oxygen content parameter or the moisture content parameter deviates from the preset impurity removal qualification line, controlling the electric regulating valve of the water circuit to increase the opening degree to increase the flow rate of the heated cooling water flowing into the heat preservation end, thereby improving the catalytic impurity removal efficiency; controlling the impurity-removed gas to enter the high-pressure press for secondary pressurization; controlling the secondary pressurized gas to enter the heater, and using the auxiliary heating wire installed inside the heater to raise the temperature to the set operating temperature.

[0027] The newly generated gaseous argon mixes with the recovered argon and enters the inlet of the intermediate-pressure compressor. An internal variable-frequency motor drives a piston to perform primary volumetric compression of the gas. The initially pressurized fluid is then fed into the purifier container. The purifier is filled with deoxygenation catalytic metal particles and porous molecular sieve dehydration material. A solid electrolyte probe and a capacitive dew point module are installed at the purifier outlet. The analog level output by the probe is calculated by the processor into digital values ​​corresponding to the oxygen and moisture content parameters. Since the chemical kinetic reaction rates of catalytic oxidation and molecular sieve adsorption depend on the physical temperature range, when the control program determines that the component parameters deviate from the preset impurity removal qualification line, it indicates that the impurity removal rate has decreased. The processor calculates the adjustment deviation and outputs a drive pulse to the electric regulating valve in the water circuit at the front end of the insulation end. Increasing the valve opening allows more heat transfer fluid to enter the insulation jacket, injecting heat into the internal bed and raising the reaction physical temperature. The purified gas is discharged into the high-pressure compressor, where a multi-stage series cylinder performs secondary compression until the critical process pressure is reached. Subsequently, the high-pressure gas flows through the heater, and the auxiliary heating wire inside, which is energized with alternating current, transfers sensible heat to the gas flow through electrothermal effect, thus locking the final delivered gas flow within the set operating temperature range.

[0028] Specifically, because high-temperature molten titanium powder is highly sensitive to interstitial solid solution impurities (easily causing hydrogen embrittlement or oxygen weight gain), the preset impurity removal qualification line has a strict industrial metallurgical composition boundary: that is, the absolute value of the real-time oxygen content in the purifier outlet gas must be... Furthermore, the pressure dew point temperature corresponding to the moisture content must be... .

[0029] When a parameter deviates from the above limits, the system invokes the incremental PI (proportional-integral) control equation to output a drive pulse. Taking excessive oxygen content as an example, the physical deviation of the concentration in the current control cycle is defined as follows: (Unit: ppm). The formula for calculating the percentage increment instruction for the opening step output by the processor to the electric regulating valve of the water circuit is as follows: .in, For the first The opening step percentage increment instruction output in each control cycle; For the first Physical deviation of oxygen concentration in each control cycle; For the first The absolute value of real-time oxygen content monitored in each control cycle; This is the proportional gain coefficient; This is the integral accumulation coefficient (used specifically to offset the static temperature difference caused by the heat capacity of the water jacket). For the first Concentration deviation per control cycle; This represents the discrete control cycle number, which is a positive integer. In practical engineering applications, the proportional gain coefficient... With integral cumulative coefficient The algebraic increment is obtained during the system's factory commissioning phase using the Ziegler-Nichols step response method, based on the specific thermal capacity and inertia of the purifier's insulation jacket. This value is then permanently stored in the processor's non-volatile memory. It is directly mapped to a duty cycle-controlled PWM (Pulse Width Modulation) analog signal, which precisely drives a stepper motor to change the valve core displacement. This rule establishes a deterministic mathematical linkage between microscopic impurity concentration deviation and macroscopic mechanical valve action step size.

[0030] Furthermore, regarding step S30, the step of controlling the exhaust gas discharged from the electrode induction melting gas atomization device to be drawn by the argon blower to form the recovered argon gas includes: setting a dust filter screen at the end of the exhaust channel of the electrode induction melting gas atomization device; using the negative pressure suction force of the argon blower to draw the exhaust gas containing metal dust to the dust filter screen for solid-gas separation; and sending the purified gas after the dust separation as the recovered argon gas into the air inlet of the medium-pressure machine.

[0031] The exhaust chamber of the electrode-induction melting gas atomization device is filled with a mixed fluid containing solid metal particles. The dust filter screen is composed of multiple layers of sintered metal wires woven to form a microscopic obstruction path. The intelligent system regulates the operation of the argon gas fan, and the rotating impeller creates a suction negative pressure flow field. Fluid dynamic pressure controls the mixed exhaust gas to pass through the obstruction path. Solid metal dust is retained on the surface of the metal wires due to the inertial deposition effect caused by streamline deflection. The gas after solid-gas separation flows through a sealed duct into the front-end convergence node of the gas supply return flow, serving as recovered material for subsequent pressurization processes.

[0032] Furthermore, regarding steps S50 and S60, the step of calculating the fluid transport lag time window encountered by the system cooling water in transporting the waste heat of the intermediate compressor to the liquid argon vaporization module includes: reading the total length of the physical pipeline between the heat exchange port of the intermediate compressor and the heat exchange port of the liquid argon vaporization module; obtaining the current transport speed of the system cooling water in the main pipeline; dividing the total length of the physical pipeline by the current transport speed to obtain the basic physical transport time; and introducing the thermal conductivity resistance coefficient of the equipment shell to correct and extend the basic physical transport time to obtain the fluid transport lag time window.

[0033] In the calculation model for acquiring the slope parameter, the processor acquires real-time pipeline pressure digital sequences under fixed-clock sampling interruption. The algorithm model uses the discrete difference formula to extract the pressure difference value corresponding to adjacent sampling nodes, and performs a quotient operation with the time step to obtain the dynamic gas pressure drop slope parameter that quantifies the attenuation rate of the pressure field. When the calculated value exceeds the set alarm limit, it indicates that the external supplementary heat flux required by the gasification module has increased. The processor reads the total length of the spatial physical pipeline stored in the memory parameter table. A time-difference ultrasonic flow probe is attached to the main pipeline. The time difference between the downstream and upstream transmission of the ultrasonic signal is interpreted as a variable of the linear velocity of the water body and assigned to the current delivery speed. The arithmetic module executes a division instruction to calculate the basic physical transmission time based on the quotient of length and speed. Thermodynamic control incorporates the thermal conductivity time resistance of the metal entity and retrieves the thermal conductivity hysteresis coefficient of the equipment shell determined by the physical material properties. The hysteresis coefficient is accumulated and calculated into the transmission time through arithmetic compensation operation to lock the fluid transmission hysteresis time window. The fluid transport hysteresis time window parameter defines the deterministic physical time period from the waste heat generation node to the liquid argon heat exchange interface.

[0034] Furthermore, in steps S70 and S80, within the defined fluid transmission period, the system executes the water distribution valve to cut off the heat transfer fluid originally intended to be delivered to the heat preservation end of the purifier, and urgently directs the waste heat intended to be delivered to the purifier to the liquid argon vaporization module to compensate for the surge in cold load caused by vaporization.

[0035] The step of issuing an internal airflow swirl command to the intermediate compressor and controlling the intermediate compressor to generate transient compensating heat energy through gas compression and frictional self-excitation includes: calculating the total amount of heat energy loss faced by the purifier due to the emergency diversion of the waste heat; increasing the operating frequency of the intermediate compressor while maintaining the gas flow rate output from the intermediate compressor to the purifier; simultaneously opening the bypass return channel inside the intermediate compressor, allowing the additional gas to perform high-frequency reciprocating circulation between the internal cylinder and the bypass return channel; and using the intermolecular shear force and aerodynamic friction force of the pipe wall caused by the high-frequency reciprocating circulation to convert the additional mechanical work into transient compensating heat energy that matches the total amount of heat energy loss.

[0036] Under the influence of this guided transfer physical action, the purifier faces the risk of cooling. The processor extracts the mass flow rate variable of the transferred heat medium water, and performs definite integral calculations based on the constant pressure specific heat capacity constant and temperature difference variable to obtain the total amount of heat energy missing that the system needs to maintain the baseline temperature for catalytic purification. After locking the target heat value, the microprocessor maintains the normal exhaust main valve opening parameter, and simultaneously inputs a high-level control command to the variable frequency drive terminal of the medium-pressure motor, increasing the AC power supply frequency of the motor stator. The increased spindle speed increases the cylinder throughput. The processor synchronously outputs an opening signal to the electromagnetic bypass valve connecting the high-pressure exhaust chamber and the low-pressure intake chamber of the medium-pressure motor, opening the bypass return channel. The overflowing extra compressed gas enters the bypass return channel under the pressure difference inside the chamber and returns to the intake end. The gas molecules are confined within the return path, undergoing compression work, passing through the throttling orifice, and experiencing frictional damping along the way. The extra mechanical work output by the motor is converted into dissipated heat energy through the physical effect of gas friction, forming the transient compensation heat energy.

[0037] Furthermore, regarding step S90, the step of transferring the transient compensation heat energy to the purifier nearby to maintain the set temperature threshold required for impurity removal includes: monitoring the real-time temperature slope of the catalyst bed inside the purifier; dynamically controlling the generation rate of the transient compensation heat energy by adjusting the throttling opening of the bypass reflux channel; directionally conducting the generated transient compensation heat energy to the catalyst bed through a local short heat conduction pipe; ensuring that the real-time temperature slope remains stable at all times to avoid the effective failure of the impurity removal process due to the impact of cold airflow.

[0038] The armored thermocouples embedded inside the catalytic bed continuously return voltage fluctuation signals. The processor performs periodic discrete sampling and slope analytical differential calculations to obtain the real-time temperature slope variable representing the dynamic changes in the temperature field. Based on the calculated slope deviation, the control program outputs adjustment parameters to fine-tune the bypass reflux channel valve, reducing or increasing its size. The change in the throttling opening alters the fluid resistance coefficient encountered by the circulating gas, dynamically adjusting the heating power generated per unit time from mechanical work. Relying on the physical layout of the adjacent spatial arrangement between the medium-pressure compressor shell and the purifier shell, the dissipated heat is injected into the purifier's insulation jacket area via the local short heat-conducting pipe, ensuring stable material purification temperature indicators.

[0039] Specifically, the discrete difference calculation formula for the slope of the dynamic gas pressure drop is defined as follows: .in, The slope of the dynamic gas pressure decrease; This is the digital sample value of the absolute air pressure in the pipeline for the current cycle; This is the air pressure sampling value from the previous cycle; The fixed sampling time step is set (preferably set to 0.5 seconds to filter out high-frequency aerodynamic noise).

[0040] The set alarm limit is defined based on the ultimate drop rate of the physical volume of the gas supply network under conditions that do not trigger process pressure loss and backflow. The derivation formula is as follows: .in, To set alarm limits; This refers to the maximum gas consumption volume flow rate of the electrode induction melting gas atomization equipment under peak operating conditions. To calibrate the working air pressure; The total physical buffer volume of the main gas supply pipeline; This is a safety margin conversion factor for the pipeline network (with a value between 0.80 and 0.85). Based on the hardware specifications of a conventional medium-sized titanium powder atomization system, the calibration is performed. In this embodiment, the engineering value range for the set alarm limit is configured between 0.05 MPa / s and 0.15 MPa / s.

[0041] Furthermore, the penetration of waste heat from the inner cavity of the intermediate compressor to the external cooling water inevitably involves a time delay due to the thermal inertia of the metal physical entity. The thermal resistance coefficient of the equipment casing is here quantified as a heat transfer time constant. (Unit: seconds). Based on the transient heat conduction reduced-order physical equation, the specific derivation formula is as follows: .in, is the heat transfer time constant (i.e., the thermal resistance coefficient of the equipment shell). Density of the metal shell material for the heat exchange jacket of the medium-pressure compressor (unit: ); The specific heat capacity of this material (unit: ); The average physical wall thickness between the jacket and the cylinder cavity (unit: ); The thermal conductivity of this material (unit: The arithmetic compensation process for obtaining the fluid transport hysteresis time window is to reduce the basic physical transport time. With this constant Perform linear summation in the time dimension, i.e. .in, This is the final calculated fluid transport hysteresis time window; This is based on the physical transmission time. This process effectively eliminates the time prediction blind spot caused by heat exchange delay at the physical level.

[0042] Furthermore, definite integral calculations are used to accurately quantify the sensible heat gap in the purifier faced by the system within the time window of water flow lag. The specific mathematical expression is as follows:

[0043] in, Represents the calculated total heat energy deficit target value (unit: joules); lower limit of integration This represents the start time of the action that triggers the emergency diversion of the predetermined waste heat; the upper limit of integration is the duration of the fluid transport hysteresis window calculated above. ; The instantaneous mass flow rate of the heat transfer medium water that was forcibly transferred was obtained in real time using an ultrasonic flow probe (unit: ); The constant pressure specific heat capacity constant of cooling water (values) ); The steady-state inlet temperature of the water flow originally intended to flow into the purifier at the thermal hub; To maintain the activity of the porous molecular sieve and deoxygenation catalyst inside the purifier, a minimum operating critical temperature was set (calibrated to 160°C in this embodiment). This is the independent variable for continuous-time integration within the fluid transport hysteresis window. The formula precisely quantifies the heat flux transferred by fluid reversal into the exact Joule value required for subsequent mechanical friction compensation. The processor internally has precisely defined step-wise dead-zone control criteria. The formula for calculating the real-time temperature slope deviation of the catalytic bed in the extraction purifier is as follows: .in, This represents the real-time temperature slope deviation. The actual temperature change slope (negative values ​​represent temperature loss and cooling, positive values ​​represent temperature increase, unit: ...) ); The ideal constant-temperature slope for the process.

[0044] In addition, the system follows the action instruction determination mapping table as follows: when When the heat compensation is determined to be within the dead zone range where the system's thermal inertia can be mitigated, a maintenance command is output to keep the current throttling opening of the bypass return channel and the current operating frequency of the intermediate compressor unchanged. when When a slow temperature loss is detected, a step amplification command is output to increase the throttling opening by 15% based on the current command, thereby increasing the internal circulating air volume and enhancing the power of fluid shearing and aerodynamic friction heating. when When the system is deemed to be facing a serious risk of failure of the catalytic microstructure due to cold penetration, it triggers a step intervention command to adjust the throttling opening to 80% of the physical safety limit and simultaneously sends a command to the medium-pressure machine frequency converter to increase the operating frequency by 5Hz, instantly maximizing the use of mechanical compression and pipe wall friction to convert peak compensation heat energy. when When the system determines that excessive compensating heat energy has caused temperature overshoot, it outputs a step reduction command, decreasing the throttling opening by 10% per second until the bypass return channel is completely closed. This rule table establishes a direct and unique execution relationship between the cooling gradient and the mechanical heating power.

[0045] To achieve decoupled control between constant output fluid and compensating heat generation, this system constructs a feedforward algebraic analytical model based on the laws of mass conservation in fluid mechanics and energy conservation in engineering thermodynamics. Specifically, the steps for solving the simultaneous equations of the specific parameters executed by the processor are as follows: The system extracts the total amount of heat energy deficit calculated above. Duration of fluid transport hysteresis window The target compensation heat power that must be continuously supplied during this lag period is obtained through quotient calculation: (Unit: W). Among them, To compensate for thermal power for the target.

[0046] Because the mechanical shaft work undergoes irreversible thermodynamic dissipation during pneumatic compression, bypass throttling, and heat conduction through the shell, the system incorporates a comprehensive heat transfer efficiency coefficient. (Given that the intermediate-pressure compressor and the purifier are directly connected via a short local heat-conducting pipe and a jacket, this embodiment uses the thermal resistance properties of solid metal materials to fix the coefficient between 0.80 and 0.85.) The actual effective mechanical power that the intermediate-pressure compressor must add is calculated as follows: .in, The effective mechanical power that must be added to the medium-pressure press.

[0047] To ensure the intermediate-pressure compressor accurately outputs this mechanical power, the microprocessor invokes the underlying physical equations of power loss during multi-directional adiabatic compression of single-atom gas, and inversely calculates the increment of the reference operating frequency that the variable frequency drive motor must adjust upwards. (Unit: Hz), the formula is: ; In the formula, The increment of the reference operating frequency; The physical geometric displacement constant of a single reciprocating motion of the piston in the cylinder inside the intermediate pressure compressor ( ); The number of pole pairs of the variable frequency motor (used to establish the ratio of frequency to speed); This represents the actual volumetric efficiency of the cylinder under the current pressure drop condition. and These are the absolute pressure parameters (Pa) at the compressor intake and exhaust ends, respectively, collected in real time by the bottom absolute pressure sensor. The adiabatic index of gaseous argon (argon is a monatomic ideal gas, and this physical constant is 1.66). The processor generates feedforward frequency step control instructions based on this equation: , and issued. The target operating frequency for the feedforward frequency step control command. This represents the motor's current actual operating frequency.

[0048] Finally, to meet the control boundary condition of constant gas flow rate output to the downstream pipeline network, the additional gas volumetric throughput caused by the aforementioned frequency increase must be completely intercepted by the internal return path through a closed loop. The control program synchronously calculates the instantaneous bypass volumetric flow rate based on the volumetric flow law: .in, For instantaneous bypass volumetric flow rate, the processor utilizes the standard flow coefficient equation for fluid control valves: .in, This is the standard flow coefficient for fluid control valves (i.e., bypass valves); This represents the real-time density under gaseous argon inlet conditions. The chip uses reverse addressing of the built-in electromagnetic bypass valve. The factory physical characteristic mapping table for the value-mechanical opening percentage directly outputs the initial opening displacement level corresponding to the cross-sectional area. This factory physical characteristic mapping table is a deterministic data array pre-programmed offline into the system's read-only memory during system initialization configuration or hardware replacement, strictly adhering to the datasheet provided by the selected electromagnetic bypass valve hardware manufacturer, without relying on dynamic learning during runtime.

[0049] Through simultaneous algebraic decoupling of the aforementioned physical equations, the system effectively quantifies macroscopic functional requirements into microscopically determined motor Hertz (Hz) increments and valve opening step sizes. This model establishes the compensation benchmark, and combined with the variable temperature slope feedback dead zone fine-tuning (feedback correction) mentioned in point four above, a combined electromechanical linkage architecture of feedforward tuning and feedback closed-loop optimization is constructed. The physical mapping relationship determined by the above decoupling model avoids the risk of global thermodynamic imbalance caused by parameter uncertainties.

[0050] Furthermore, such as Figure 6 As shown, the control method further includes a smooth recovery step after the fluid transport hysteresis time window ends: Step S100: Start the time accumulation counter and continuously track and record the length of time consumed; Step S110: When the time consumed reaches the boundary node of the fluid transport hysteresis time window, it is determined that the waste heat discharged by the intermediate compressor has arrived at the heat distribution hub along with the system cooling water. Step S120: Immediately cancel the emergency guidance action of the waste heat to the liquid argon vaporization module and restore the normal waste heat distribution ratio; Step S130: Simultaneously terminate the internal airflow swirl command, causing the medium-pressure compressor to return to the standard power consumption operation mode.

[0051] Within the same clock cycle that triggers the heat compensation action, the microprocessor's internal timing structure is activated. The algorithm model performs discrete-time step-by-step accumulation, generating a count value of the consumed time length. The control program cyclically compares the time count value with the fluid transport hysteresis time window parameter. When the values ​​are equal, the logical calculation result indicates that the heat front previously extracted at the intermediate-pressure side has moved along the pipeline to the distribution node. The system then sends a power control reset signal to the branch reversing valve to reconstruct the normal heat medium transport ratio to the multiple heat load nodes. Simultaneously, the microprocessor outputs a control command to cut off the physical path of the gas bypass circulation and instructs the motor inverter to lower its operating frequency to the steady-state parameter point required for normal transport, stopping internal frictional heat generation. The entire system's flow field and thermodynamic field transition complete the physical steady-state recovery.

[0052] Furthermore, regarding the core scheduling indicators in the aforementioned smooth recovery steps, the normal waste heat allocation ratio is a benchmark parameter established based on the differences in steady-state thermodynamic loads of each physical module. Specifically, the allocation is based on the following physical basis: the phase change of liquid argon (approximately -186°C) to gaseous argon requires the absorption of a large latent heat of vaporization (approximately 161.6 kJ / kg), making its required heat flux the most significant; while the purifier only needs to supplement the heat leakage from the outer shell to maintain the activation temperature of the internal catalytic bed (approximately 160°C), and the heater is used for basic gas sensible heat preheating. Therefore, by adjusting the basic flow resistance coefficient (Cv value) of the electric regulating valves at the front end of each branch pipeline during system initialization, the normal waste heat allocation ratio is set as follows: the heat medium flow rate allocated to the liquid argon vaporization module accounts for 60%–65% of the total system circulation flow rate, the allocation to the purifier accounts for 15%–20%, and the allocation to the heater accounts for 15%–20%. The aforementioned three-way static flow ratio, locked by physical hardware, provides a fundamental thermodynamic origin reference for the transient thermodynamic scheduling and precise reset initiated by this invention when facing fluid hysteresis.

Through internal logic computing power and interconnection with field hardware, the intelligent system independently completes a closed-loop control process including parameter acquisition, fluid measurement, timing determination, and mechanism driving, establishing a thermal compensation and pipeline balance architecture under physical constraints.
