Detailed Description
For the purpose of making apparent the objects, technical solutions and advantages of the present application, the present application will be further described in detail with reference to the following examples and the accompanying drawings, wherein the exemplary embodiments of the present application and the descriptions thereof are for illustrating the present application only and are not to be construed as limiting the present application.
Example 1: a method for adaptively regulating and controlling the feeding amount of a reaction container is shown in figure 1, and is specifically realized by the following steps.
Step one: and collecting a real-time temperature value of a chemical reaction system in the reaction container, and generating a start regulation signal when the real-time temperature value reaches a constant temperature value. Wherein, the real-time temperature value can adopt a temperature sensor or other devices capable of temperature acquisition.
It should be noted that the chemical reaction system in this embodiment refers to all materials in the reaction vessel, and assuming that the initial mixture in the chemical reaction system includes materials a and B, with the addition of material C (to be added), the whole reaction system includes materials A, B, C and the mixed reaction products of materials A, B and C.
Step two: and determining the material quantity of the to-be-added substances corresponding to the critical points of the temperature and the concentration on the reaction rate as an initial material quantity according to a reaction rate table, wherein the reaction rate table comprises the reaction rates of the to-be-added substances with different concentrations in chemical reaction systems at different temperatures.
Specifically, the reaction rate table is established by the following steps: determining the maximum concentration value of the substance to be added in the chemical reaction system according to the total material quantity of the substance to be added and the volume of the chemical reaction system, and obtaining a concentration variable range; determining a temperature variable range according to a constant temperature value of an object to be added in a chemical reaction system; and establishing a reaction rate table of the concentration of the substance to be added in a concentration variable range and the temperature of the chemical reaction system in a temperature variable range.
Taking the example that the initial mixture in the chemical reaction system includes substances A and B, the temperature value in the chemical reaction system is T1. If the molar amount of substance C to be added is X to ensure adequate reaction of substances A, B and C, the constant temperature required for the reaction is T2, T2 being greater than T1.
If the substance C is added to the initial mixture at one time, the lowest temperature of the substance C is the temperature T0 when the substance C is not added, the highest temperature of the substance C is the constant temperature value required by the reaction and is T2, so the temperature variable range is T0-T2.
The lowest value in the concentration variable range is 0 when the substance C is not added yet; the concentration C1 at the time of adding the substance C having the molar amount X is the maximum concentration, so that the concentration variable range is 0 to C1.
The established reaction rate table includes all reaction rates at which substance C reacts with substances a and B when the reaction conditions consisting of the concentration variable range and the temperature variable range are satisfied.
It should be noted that, each reaction rate in the reaction rate table may be obtained by adopting an analog simulation method, or may be obtained by performing a limited experiment after taking points at intervals of temperature and concentration, and then performing a least square method on limited experimental data to perform fitting so as to complement missing data.
In addition, the reaction rate table may be represented by a specific reaction rate value; the method can also normalize each reaction rate, retain normalized standard values, and can be used for solving the specific reaction rate in an inverse way by combining the standard values after reading the normalized values; the reaction rate may also be represented by a gray value, and the reaction rate table is displayed in a gray map.
Specifically, the determination process of the initial material amount is as follows: acquiring a first temperature-rising change curve of a chemical reaction system, wherein the first temperature-rising change curve is obtained by heating to a constant temperature value after adding a material to be added with a preset material quantity; obtaining a second temperature-rising change curve of the total material amount added to the chemical reaction system, wherein the temperature of the material to be added is raised to a constant temperature value; intercepting a temperature rise change curve section of corresponding time from the second temperature rise change curve according to the temperature rise time of the first temperature rise change curve; and solving by taking the first material quantity consumed by the reaction in the first temperature rise change curve not smaller than the second material quantity consumed by the reaction in the temperature rise change curve section as an optimization target to obtain the minimum preset material quantity, wherein the minimum preset material quantity is used as the initial material quantity.
The first temperature rise change curve and the second temperature rise change curve are both T-T curves, the abscissa is time T, and the ordinate is temperature T.
It should be noted that the initial material amount to be solved is required to ensure that the concentration of the material to be added is not 0 before the temperature is raised to a constant temperature value.
Because the preset material amount is smaller than the total material amount, the reaction rate of the first temperature rising change curve in the initial stage is necessarily smaller than that of the second temperature rising change curve in the initial stage under the condition that the initial temperature of the chemical reaction system is the same. And the temperature of the object to be added is slowly increased and then rapidly increased under the action of the constant temperature heat source, so that the reaction rate in the unit time at the tail stage of the temperature increase is greatly changed; at a constant temperature, the reaction rate decreases rapidly and then slowly as the concentration of the reactant decreases. It is found that, when the concentration is not large, the reaction rate changes less in the stage unit time as the concentration is smaller. The reaction rate of the first heating-up change curve in the initial part time is smaller than that of the heating-up change curve section in the initial part time, then the reaction rate of the first heating-up change curve section in the middle part time can be reversely exceeded by the reaction rate of the first heating-up change curve section in the middle part time, then the reaction rate of the heating-up change curve section in the last part time can be reversely exceeded by the reaction rate of the first heating-up change curve section in the later part time, and therefore the reaction rates corresponding to the first heating-up change curve and the heating-up change curve section inevitably have crossing points.
Assuming that the preset material amount is X1, the total material amount is X, and X1 is smaller than X. If X1 is added to the initial mixture, the time required for the temperature to rise to T2 is T1. If the substance to be added of X is added to the initial mixture, the time required for heating to T2 is T2, and T1 is smaller than T2. The temperature rise change curve segment is a curve corresponding to the time 0-t 1 in the second temperature rise change curve. At this time, in combination with the reaction rate table, the first material amount y1 consumed by the reaction in the first temperature-raising change curve and the second material amount y2 consumed by the reaction in the temperature-raising change curve section are respectively statistically analyzed by adopting accumulation summation, and the unique minimum preset material amount is obtained by solving under the constraint condition that y1 is larger than y2, namely, the initial material amount.
The application shortens the time of constant temperature value of the temperature rising value of the chemical reaction system by reducing a certain amount of materials, and can use the larger influence of temperature on the reaction rate to mention the smaller influence of concentration on the reaction rate, thereby improving the overall reaction rate.
It should be noted that, in the process of optimizing and solving the initial material quantity, the preset material quantity may dynamically change according to the difference between the first material quantity and the second material quantity; if the second material quantity is larger than the first material quantity, presetting the material quantity to be presented and changed; if the first material amount is larger than the second material amount, the preset material amount is changed in a decreasing manner. For example, a dichotomy method is adopted to quickly solve the initial material quantity, taking 0-100 as an example, assuming that one preset material quantity is randomly selected to be 50, and if the calculated second material quantity is larger than the first material quantity, the preset material quantity randomly selected in the next optimization solution is 75; otherwise, if the first material amount is larger than the second material amount, the preset material amount randomly selected in the next optimization solving is 25, and so on until the minimum preset material amount is obtained by solving and is used as the initial material amount.
In addition, the dynamic change process of the preset material quantity specifically comprises the following steps: determining the absolute value of the difference value between the second material quantity and the first material quantity to obtain a difference value; the single variation of the preset material quantity is positively correlated with the difference quantity.
In the process of optimizing and solving the initial material quantity, the method dynamically regulates and controls the single variation of the preset material quantity according to the absolute value of the difference value between the second material quantity and the first material quantity, and can quickly solve the initial material quantity.
Step three: and collecting or simulating and analyzing the total material amount of the material to be added in the chemical reaction system in the reaction container, and outputting a closing regulation signal after the total material amount of the material to be added exceeds the initial material amount.
In addition, the method can also be used for circularly adding the adding amount of the object to be added after the chemical reaction system is heated to a constant temperature value, and generating a closing regulation and control signal after the feeding component outputs the adding amount.
As an alternative embodiment, the calculation process of the addition amount specifically includes: calculating the consumption of the to-be-added object between the last cyclic addition of the to-be-added object and the current moment; the consumption is taken as the addition amount of the substance to be added in the current cycle period. According to the application, the consumption of the to-be-added substances in the previous cycle is used as the addition of the to-be-added substances in the current cycle, the integral reaction rate is improved by continuously shortening the time of the cycle, and the method is more suitable for a chemical reaction system which is easy to heat.
As another alternative, the amount of material to be added is the initial material amount for each cycle. According to the application, the to-be-added substances with the initial material quantity are added in each circulation, and the integral reaction rate is improved by continuously improving the concentration in each circulation period, so that the method is more suitable for a chemical reaction system which is easy to diffuse uniformly.
Step four: and controlling the feeding assembly to add the substance to be added into the reaction vessel after responding to the start regulation signal, and controlling the feeding assembly to stop adding the substance to be added into the reaction vessel after responding to the stop regulation signal.
As shown in FIG. 2, the reaction rate of the material to be added is controlled by the method according to the application at intervals, the abscissa is time, and the ordinate is reaction rate, compared with the single-peak reaction rate variation form of the conventional material added at one time, the reaction rate is more balanced and stable in the reaction process.
Example 2: a reaction vessel feeding amount self-adaptive regulation and control system is shown in fig. 3, and comprises a temperature acquisition module, a critical analysis module, a material monitoring module and a response control module.
The temperature acquisition module is used for acquiring a real-time temperature value of a chemical reaction system in the reaction container and generating a starting regulation signal when the real-time temperature value reaches a constant temperature value; the critical analysis module is used for determining the material quantity of the to-be-added substances corresponding to the critical point of the influence of the temperature and the concentration on the reaction rate as an initial material quantity according to a reaction rate table, wherein the reaction rate table comprises the reaction rates of the to-be-added substances with different concentrations in chemical reaction systems at different temperatures; the material monitoring module is used for collecting or simulating and analyzing the total material amount of the to-be-added material in the chemical reaction system in the reaction container, and outputting a closing regulation signal after the total material amount of the to-be-added material exceeds the initial material amount; and the response control module is used for controlling the feeding assembly to add the substance to be added into the reaction vessel after responding to the start regulation signal and controlling the feeding assembly to stop adding the substance to be added into the reaction vessel after responding to the closing regulation signal.
Working principle: the method reduces the concentration of the substances to be added in the early temperature rising stage in the chemical reaction system to optimize the temperature rising speed of the chemical reaction system, and controls the feeding amount circularly by balancing the influence of the temperature and the concentration on the reaction rate of the substances to be added and controlling the total amount of the substances to be added to be not lower than the initial material amount, thereby not only improving the overall reaction rate to a certain extent, but also enabling the reaction rate of the whole reaction process to fluctuate in a smaller range, being beneficial to accurately controlling the gas to be treated in the chemical reaction system and ensuring the stability of the chemical reaction process; in addition, in the whole reaction process, a constant-temperature heat source with fixed power can be adopted for heating, and the power of the constant-temperature heat source is not required to be regulated and controlled.
