Abstract
Description
Technical Field
[0001] This invention relates to the field of air tritized water sampling, and more particularly to an air tritized water sampling method and system for all climates. Background Technology
[0002] Existing air tritized water sampling methods typically operate based on fixed or empirical parameters (such as sampling flow rate, adsorbent replacement cycle, and temperature control threshold). However, under "all-climate" conditions (i.e., environments that change rapidly or are extremely cold and dry to hot and humid), these fixed parameters significantly reduce sampling efficiency and accuracy. Specifically, under low temperature and high humidity conditions, water vapor easily condenses or freezes, blocking the flow path; under high temperature and dry conditions, the adsorbent may become saturated prematurely or undergo desorption; and under rapidly changing climate conditions, a single parameter cannot adaptively optimize, leading to incomplete tritized water collection or distorted concentration measurements. Currently, there is a lack of an intelligent control method capable of sensing multi-dimensional environmental variables in real time and dynamically and collaboratively adjusting key sampling parameters to ensure stable, efficient, and high-precision tritized water sampling under any climatic conditions.

[0032] Example 1
[0033] like Figure 1 As shown, Embodiment 1 of this application provides a method for sampling air tritium water for all climates, including:
[0034] Step S10: Real-time acquisition of four environmental parameters at the sampling point: temperature, relative humidity, atmospheric pressure, and air velocity;
[0035] A multi-parameter environmental sensing unit is deployed at the sampling point. This unit includes at least a temperature sensor, a relative humidity sensor, an atmospheric pressure sensor, and an air velocity sensor. Each sensor is located near the sampling inlet and exposed to the same environmental conditions to ensure that the measured parameters are consistent with the state of the air to be sampled. The output signals of each sensor are collected synchronously at a preset sampling frequency (once per second to once per minute, which can be configured according to requirements). The acquisition process is marked with timestamps to ensure that the four types of data, namely temperature, relative humidity, atmospheric pressure, and air velocity, are aligned in time. Based on the sensor calibration parameters and conversion relationship, the digital signals are converted into actual physical quantity values.
[0036] Step S20: Input the real-time acquired environmental parameters into the preset dynamic parameter generator and output a set of optimized key sampling parameter combinations;
[0037] The dynamic parameter generator is a virtual dynamic system describing the interaction between the microclimate and sampling processes. By solving the optimization problem of this system under specific boundaries, the optimal control parameters are derived. The specific construction and solution process is as follows:
[0038] Step S21: Define the system state variables and control input vector of the sampling device;
[0039] The system state variables of the sampling device are described by two coupled variables: A dimensionless state quantity used to characterize the effective adsorption potential of the adsorbent for tritized water at time t. The icing / over-analysis risk coefficient is used to characterize the sampling flow path interface at time t.
[0040] The control input vector is defined as , Let be the normalized rate of the sampling pump at time t. The temperature adjustment amount of the temperature control device at time t (relative to the ambient temperature).
[0041] Step S22: Using the obtained environmental parameters, construct the evolution equations of the system state variables;
[0042] Based on the principles of mass and energy transfer, the system state variables are constructed using real-time acquired data such as temperature T, relative humidity H, atmospheric pressure P, and air velocity V. and Evolution equation:
[0043]
[0044]
[0045] in For reference relative humidity, it is usually set to the humidity value under standard operating conditions or typical working environment. In this embodiment, it is set to 50%, which is used to perform dimensionless normalization of real-time humidity. The optimal temperature for the adsorbent to operate; The temperature-sensitive time constant is used to reflect the sensitivity of the adsorption process to temperature. It is estimated by conducting adsorption kinetic experiments under different isothermal conditions and fitting the curve of adsorption capacity changing with time. Standard atmospheric pressure; Let t be the normalized rate of the sampling pump at time t; The dissipation coefficient of the adsorption potential is given by the risk of freezing / over-desorption, characterizing the dissipation coefficient of the adsorption potential when the risk coefficient is... Exceeding the safety threshold At that time, its effective adsorption potential The degradation rate was obtained by fitting the adsorption performance decay data under ideal and disturbed conditions under conditions with the risk of condensation or high temperature. The intensity coefficient of the high-temperature analytical effect; The shape parameter is used to clarify the effect of high-temperature analysis, i.e., it intensifies with increasing temperature. and The results were obtained by fitting the analytical kinetics data of the adsorbent at high temperature. The high-temperature desorption risk threshold is the rate at which the adsorbent desorbs (desorbs) the captured tritium water when the temperature exceeds this value. This value is determined by thermogravimetric analysis (TGA) or temperature-programmed desorption (TPD) experiments on the adsorbent material. This is the critical threshold for high humidity condensation. When the relative humidity of the environment exceeds this value, the risk of water vapor condensation or ice formation on the flow path or adsorbent surface increases sharply. Its value is obtained through experimental observation. To mitigate the risk of condensation at critical humidity The smaller the value of the transition width, the more abrupt the transition, indicating that condensation occurs faster near the critical point. This parameter can be identified through experiments on humidity step changes and by observing the system response (such as the time it takes for an optical sensor to detect condensation). The reference air velocity is the rated operating velocity of the sampling pump. The temperature adjustment amount of the temperature control device at time t; This is a scaling parameter for temperature deviation, used to measure temperature deviation. Dimensionless; The weighting coefficients for the tendency of condensation are determined through condensation experiments under controlled humidity and flow rate. The weighting coefficient for the impact of temperature deviation on risk reflects the enhanced effect of actual temperature deviating from the optimal temperature on the risk coefficient. It is calibrated by testing the change of the risk coefficient under different temperature settings. Risk decay rate is the rate at which the risk coefficient decreases by the system itself (e.g., through equilibrium diffusion) without external driving force. It can be estimated by observing the decay process of risk indicators (e.g., pressure difference, humidity) after temperature control is stopped in a stable environment.
[0046] The coefficient characterizes the rate at which the risk of condensation increases, driven by both ambient humidity and flow velocity. Its specific calibration procedure is as follows:
[0047] Keep the ambient temperature within a safe range to avoid triggering the risk of high-temperature desorption, turn off the temperature control device, fix the atmospheric pressure and air flow rate, and rapidly increase the relative humidity from a low level (30%) to above the critical value and keep it stable.
[0048] An optical transmittance sensor was used to monitor changes in light scattering intensity in the flow path window caused by fogging / icing, and the monitored raw signal was normalized to a risk factor. ;
[0049] Under these experimental conditions, the risk coefficient will be... The dynamic evolution equation is discretized, and a formula for the sum of squared errors between predicted and measured values is constructed. This sum of squared errors is then minimized using an optimization algorithm (such as Levenberg-Marquardt) to obtain the result. ;
[0050] After discretization, Predicted value of risk coefficient at any time The calculation formula is expressed as: , where i is a discrete sampling node, for The relative humidity measurement at that moment. The sampling time interval, for The predicted risk coefficient at time 1, the predicted risk coefficient at the initial time 2, i.e. Let the measured initial value be used. It is the calibrated and known natural decay rate of risk;
[0051] The formula for the sum of squared errors is then expressed as: Where SS is the result of the sum of squared errors. for The measured risk coefficient at time SS is used, where i ranges from 1 to n, and n is the total number of sampling nodes. A nonlinear least squares optimization algorithm is employed to find the value that minimizes the SS value. The parameters are used as the final calibration result.
[0052] Step S23: Construct the decision function of the dynamic parameter generator by coupling the evolution equations of the system state variables, obtain the optimal solution of the control input vector in the finite time domain, and output the combination of key sampling parameters;
[0053] The decision function based on the dynamic parameter generator can be used in the finite time domain. Internal solution of control input vector The optimal solution is expressed mathematically as follows:
[0054]
[0055] Where J is the return value of the decision function. , , , These are weighting coefficients, used to balance adsorption efficiency, pump speed regulation energy consumption, temperature control energy consumption, and system risk, respectively. for The effective adsorption potential of the adsorbent for tritium-treated water at any given time. for The icing / over-analysis risk coefficient at the sampling flow path interface is obtained through the evolution equation of the system state variables. Specifically, based on the above evolution equation, combined with the effective adsorption potential given by the technician when the sampling device is turned on, the initial value of the risk coefficient, the real-time acquired environmental parameters, and the current... , The iterative values are calculated directly at each time step using numerical integration. and ; for Normalized rate of the sampling pump at any given time. for The temperature adjustment amount of the temperature control device is constantly monitored. This is a reference value for pump speed; The initial time of the prediction window, This is the preset prediction window size;
[0056] Its constraints are: ; ; ; ;in , These represent the upper and lower boundaries of the normalized rate of the sampling pump, ensuring that the optimized pump speed command is within the actual operating capacity of the sampling pump; T represents the current ambient temperature. , The upper and lower temperature limits that the temperature control device can adjust;
[0057] Numerical optimization methods (such as direct transcription) are used to solve for the control input vector that satisfies the above constraints and minimizes the J value. In the finite time domain Find the optimal discrete time series within the range; use this time series as the key sampling parameter combination for output.
[0058] Step S30: Dynamically adjust the sampling pump and temperature control device according to the optimized combination of key sampling parameters to perform the sampling operation;
[0059] Normalize the sampling pump rate in the key sampling parameter combination in chronological order. ,and The temperature regulation amount is converted into an actual control signal and simultaneously sent to the sampling pump and temperature regulation device of the sampling device to continuously perform the sampling operation.
[0060] Step S40: Continuously monitor the effective adsorption capacity of the adsorbent throughout the entire sampling cycle and provide users with early warning information for adsorbent replacement; specifically, this is divided into the following sub-steps:
[0061] Step S41: Calculate the remaining effective adsorption capacity of the adsorbent using the system state variables output by the dynamic parameter generator;
[0062] The real-time system state variables derived from the evolution equations of the system state variables received by the dynamic parameter generator are the effective adsorption potential at the current moment. and risk coefficient Based on the formula: Real-time calculation of the remaining effective adsorption capacity of the adsorbent ,in This represents the maximum theoretical adsorption capacity of the adsorbent. Let t be the initial time of adsorbent use, and t be the current time. As a preset risk threshold, The risk reduction factor is determined through a controllable risk experiment: under stable, non-high-temperature conditions, artificially induced... And maintain, and measure the difference in actual adsorption capacity of the adsorbent before and after. Using the formula The results were obtained through reverse fitting. for Temperature measurement at time, The preset high-temperature analysis risk threshold, The high-temperature decomposition reduction factor was calibrated through a stepped temperature rise decomposition experiment: under low-risk conditions, the temperature was stabilized at multiple levels higher than [a certain value]. The adsorbent was measured at each step of the ladder to determine its capacity loss. Using the formula The results were obtained through reverse fitting. For indicator functions, when The value is 1 if it is true, and 0 otherwise.
[0063] Step S42: Based on the historical monitoring sequence of the remaining effective adsorption capacity of the adsorbent, estimate the adsorbent failure time and generate early warning information for adsorbent replacement;
[0064] The system records the calculation results of the remaining effective adsorption capacity of the adsorbent in real time and organizes them into a time series; a linear fitting method is used to establish the historical remaining effective adsorption capacity. The formula relating to time t is: ,in Let be the decay rate, and b be the fitting constant. The solution is obtained using the least squares method. With b; then let the fitting formula in (Preset adsorbent failure threshold) to deduce failure time Calculate the current remaining usage time. (Current moment); A warning message will be displayed to the user via a pop-up window: The estimated remaining usage time of the adsorbent is...
