Detailed Description
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments. Referring to fig. 1, which is an exemplary flowchart of an ion exchange ultrapure water device control method according to some embodiments of the present application, the ion exchange ultrapure water device control method 100 mainly includes the steps of:
in step 101, gel ionization parameter values of gel resin exchange ultrapure water in the ion exchange ultrapure water device are sampled, and a gel ionization parameter value sequence is determined from the sampled gel ionization parameter values.
Ion exchange ultrapure water is a water treatment technology, and the principle is that ion exchange resin is utilized to remove ions in water, the ion exchange resin is a high molecular compound, has a specific structure and can selectively adsorb and release the ions in water, wherein gel resin is one of the ion exchange resins, and the gel resin is suitable for adsorbing inorganic ions and has a smaller diameter of generally 0.3-0.6 nm.
In particular, the gel ionization parameter values when the gel resin exchanges ultrapure water are sampled at equal time intervals, for example, by a gel resin exchange ultrapure water device, the gel ionization parameter values sampled every 1 hour are set, the ionization parameter values sampled at 1 hour are X1, the ionization parameter values sampled at 2 hours are X2, the ionization parameter values sampled at 3 hours are X3, and so on, and all the gel ionization parameter values within the sampling time are obtained.
In specific implementation, the gel ionization parameter values obtained by each sampling are combined according to the time sequence of sampling, so as to obtain a gel ionization parameter value sequence, for example, the gel ionization parameter values are sampled every 1 hour, and the following data are obtained: hour 1: x1=10, 1 h: x2=12, hour 2: x3=15, 3 rd hour: x4=14, 4 th hour: x5=11, 5 th hour: x6=13, then the sequence of gel ionization parameter values is: {10,12,15,14,11,13}.
The gel ionization parameter values include gel ionization pH parameter values, gel ionization temperature parameter values and gel ionization conductivity parameter values, and the gel ionization parameter value sequence is a set of data obtained by sampling the gel ionization pH parameter values, the gel ionization temperature parameter values or the gel ionization conductivity parameter values at different time points when gel resin exchanges ultrapure water in an ion exchange ultrapure water device.
In step 102, a historical gel ionization parameter value sequence is obtained, historical gel ionization parameter values in the historical gel ionization parameter value sequence are discretized to obtain gel ionization parameter dispersion, and gel ionization parameter values in the gel ionization parameter value sequence are selected according to the gel ionization parameter dispersion to obtain gel ionization selection quantity.
In some embodiments, the historical gel ionization parameter value sequence is obtained in a time sequence from an ion exchange ultrapure water parameter log that records all ionization parameter value data of the history.
In some embodiments, discretizing the historical gel ionization parameter values in the historical gel ionization parameter value sequence to obtain the gel ionization parameter dispersion specifically may adopt the following formula, namely:
Acquiring each historical gel ionization parameter value in the historical gel ionization parameter value sequence;
acquiring the total number of historical gel ionization parameter values in the historical gel ionization parameter value sequence;
determining the average value of the historical gel ionization parameter values in the historical gel ionization parameter value sequence to obtain the average value of the historical gel ionization parameter;
Determining a gel ionization parameter dispersion of the historical gel ionization parameter values from the total number of historical gel ionization parameter values and the historical gel ionization parameter mean, wherein the gel ionization parameter dispersion is determined by the following formula:
Wherein M represents the gel ionization parameter dispersion of the historical gel ionization parameter values, K represents the total number of the historical gel ionization parameter values in the historical gel ionization parameter value sequence, x i represents the ith historical gel ionization parameter value in the historical gel ionization parameter value sequence, The average of the historical gel ionization parameter values in the sequence of historical gel ionization parameter values.
It should be noted that, the historical gel ionization parameter value sequence is obtained by combining values acquired by each gel ionization parameter at different historical time points, and the gel ionization parameter dispersion is a value obtained by discretizing the gel ionization parameter values in the historical gel ionization parameter value sequence, and is used for describing trends and rules in the historical gel ionization parameter value sequence and is used as an important reference value for subsequent selected analysis, so that the evaluation of the adjustment effect can be assisted, and if the dispersion of the adjusted parameter value sequence is reduced, the adjustment process is indicated to make the data more stable, thereby achieving a better ionization effect.
In some embodiments, the gel ionization parameter values in the gel ionization parameter value sequence are selected and evaluated according to the gel ionization parameter dispersion, so that the gel ionization selection amount can be obtained specifically by the following ways:
obtaining each gel ionization parameter value from the sequence of gel ionization parameter values;
Acquiring gel ionization parameter dispersion of historical gel ionization parameter values;
Determining a gel ionization parameter adjustment efficiency parameter according to the number of all adjustment parameters involved in the gel ionization process;
determining a time information value corresponding to each gel ionization parameter value collected in the gel ionization parameter value sequence;
determining an acquisition time upper limit information value corresponding to the gel ionization parameter value in the gel ionization parameter value sequence;
Determining a gel ionization selection amount of the gel ionization parameter value according to the gel ionization parameter value, the gel ionization parameter dispersion, the gel ionization parameter adjustment efficiency parameter, the time information value and the acquired time upper limit information value, wherein the gel ionization selection amount is determined by the following formula:
Wherein W represents a gel ionization selection amount of gel ionization parameter values, ρ t represents a gel ionization parameter value with a time information value of t in a gel ionization parameter value sequence, η represents a selection coefficient, the calibration is constant, the value range is between 0 and 1, The average value of the gel ionization parameter values in the gel ionization parameter value sequence is represented, M represents the dispersion of the gel ionization parameter, l represents the acquisition time upper limit information value of the gel ionization parameter value, t represents the time information value of the acquisition gel ionization parameter value, and ω represents the gel ionization parameter adjustment efficiency parameter.
It should be noted that, in the present application, the selection is a process of determining a gel ionization selection amount, the degree of influence of the gel ionization parameter value sequence obtained by sampling on the ion exchange ultrapure water can be known by the size of the selection amount, when the gel ionization selection amount is a larger value, it is indicated that the sampled ionization parameter value is more beneficial to the ion exchange ultrapure water in the ion exchange ultrapure water process, otherwise, the influence effect is small, the beneficial to the ion exchange ultrapure water process is poor, in addition, the gel ionization selection amount is an index value measuring the gel ionization parameter value sequence obtained by sampling, and the determination of the gel ionization selection amount is used for solving the problem of poor beneficial and reference properties of sampled data in the sampling process, so as to improve the stability of the ion exchange ultrapure water process.
It should be noted that the gel ionization parameter adjustment efficiency parameter is a value determined by the number of all adjustment parameters affecting the gel ionization process, and is used to optimize the ionization process to improve the ionization efficiency, for example, 3 adjustment parameters are a gel conductivity adjustment parameter, a gel temperature adjustment parameter, and a gel pH adjustment parameter, and in specific implementation, the gel ionization parameter adjustment efficiency parameter is a value of 3.
In step 103, a desired gel ionization efficiency and a reference gel ionization efficiency of the ion-exchanged ultrapure water at each time point are obtained, a gel ionization efficiency deviation ratio is determined from the desired gel ionization efficiency and the reference gel ionization efficiency at each time point, and a corrected gel ionization value of the ion-exchanged ultrapure water is determined from the gel ionization efficiency deviation ratio and the gel ionization selection amount.
In a specific implementation, the expected gel ionization efficiency of the ion exchange ultrapure water at each time point and the reference gel ionization efficiency are obtained, wherein the expected gel ionization efficiency is determined on the basis of theoretical calculation or experiments, and represents the expected gel ionization efficiency of the gel resin exchange ultrapure water under specific conditions, and the expected gel ionization efficiency at 15 minutes at the time point after the ion exchange ultrapure water is started is 22%, the expected gel ionization efficiency at 30 minutes at the time point is 34% and the expected gel ionization efficiency at 45 minutes at the time point is 41% according to factors such as equipment design and reaction dynamics; the reference gel ionization efficiency is set according to historical data, known parameters or standards, and can be a reference value set by analyzing and processing a plurality of experimental results under similar conditions at a specific time point, for example, the reference gel ionization efficiency at 15 minutes at the time point after the start of the ion exchange of the ultrapure water is 23%, the reference gel ionization efficiency at 30 minutes at the time point after the start of the ion exchange of the ultrapure water is 30%, and the reference gel ionization efficiency at 45 minutes at the time point after the start of the ion exchange of the ultrapure water is 39%.
In some embodiments, determining the gel ionization efficiency deviation ratio from the desired gel ionization efficiency and the reference gel ionization efficiency for each time point may specifically be performed by:
determining residual values of the expected gel ionization efficiency and the reference gel ionization efficiency at each time point to obtain a gel ionization efficiency residual value sequence;
determining the average value of gel ionization efficiency residual values in the gel ionization efficiency residual sequence;
determining the fluctuation rate of gel ionization efficiency residual values in the gel ionization efficiency residual value sequence;
And obtaining the gel ionization efficiency deviation ratio of the ion exchange ultrapure water according to the ratio of the average value of the gel ionization efficiency residual values to the fluctuation rate of the gel ionization efficiency residual values.
In a specific implementation, the gel ionization efficiency residual value sequence is composed of the residual values of the expected gel ionization efficiency and the reference gel ionization efficiency at each time point, for example, the expected gel ionization efficiencies respectively corresponding to time points of 10 minutes, 20 minutes and 30 minutes are 32%, 41% and 45%, and the reference gel ionization efficiencies are 31.5%, 39% and 46%, so that the gel ionization efficiency residual value sequence is [05%,2% and-1% ].
In a specific implementation, the fluctuation rate of the gel ionization efficiency residual value may be obtained by calculating a standard deviation of gel ionization efficiency residual values in the gel ionization efficiency residual value sequence, which is not described herein.
It should be noted that, the deviation ratio of the gel ionization efficiency may help to evaluate the overall performance of the gel ionization efficiency, if the deviation ratio is close to zero or is a negative number, it indicates that the adjustment effect is better, the gel ionization efficiency is closer to the expected value, and if the deviation ratio is a positive number, it indicates that the deviation of the gel ionization efficiency from the expected value is larger, and it is necessary to further optimize the adjustment parameters.
In some embodiments, the determination of the corrected gel ionization value of the ion-exchanged ultrapure water from the gel ionization efficiency deviation ratio and the gel ionization selection amount may specifically be performed in such a manner that:
