Description

Technical Field

[0001] This application relates to the field of reactant mixing control technology, specifically to a mixing reactor for the production of black medicine and a mixing control method thereof. Background Technology

[0002] In the production of black medicine, a mixing reactor is required to mix the materials. To ensure that the materials in the mixing reactor are fully mixed, the various raw materials are evenly dispersed, and the quality of the obtained product is stable, the rotation speed of the mixing reactor needs to be controlled.

[0003] During the mixing process of materials in a mixing reactor with a fixed rotation speed, the temperature, pressure, and other data at different locations within the reactor will continuously change over time. The data collected at different locations can only reflect the situation at that specific location. It is inaccurate to evaluate the uniformity of material mixing based solely on the temperature, pressure, and other data at a single location. To avoid uneven mixing of materials in the mixing reactor leading to numerous side reactions and affecting product quality, it is necessary to accurately evaluate the uniformity of material mixing within the mixing reactor in order to determine the appropriate rotation speed of the mixing reactor. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this application provides a mixing reactor for the production of black powder and a mixing control method thereof. The specific technical solution adopted is as follows: In a first aspect, one embodiment of this application provides a mixing control method for a mixing reactor used in the production of black medicine, the method comprising the following steps: During the mixing process, the rotational speed of the mixing reactor is collected at different sampling times, and pressure and temperature data are collected at different preset positions on the inner wall of the mixing reactor at different sampling times. Based on the differences in temperature data and pressure data collected at the same time from all preset locations, the attribute count of each preset location at the same time is marked. Based on the differences in the attribute counts of all the same preset locations in the mixing reactor at adjacent times, the mixing uniformity of the mixing reactor at each time is determined. Based on the difference in mixing uniformity between adjacent sampling times and the values ​​of all pressure data of the mixing reactor at the same sampling time, the speed adjustment degree of the mixing reactor at each sampling time is obtained, and it is determined whether the speed of the mixing reactor should be adjusted. If so, the speed of the material mixing process in the mixing reactor is controlled according to the speed adjustment degree and the speed of the mixing reactor.

[0005] Furthermore, the specific method for marking the number of attributes for each preset location at the same acquisition time based on the differences in temperature data and pressure data collected at all preset locations at the same acquisition time includes: Record any acquisition time as the target acquisition time, and record any temperature sensor at any preset location as the target temperature sensor; Based on the temperature data of all preset locations collected at all collection times, obtain the temperature attribute of each preset location at each collection time; Based on the pressure data collected at all preset locations at all acquisition times, the pressure attributes of each preset location at each acquisition time are determined. Based on the temperature and pressure attributes of the same preset location at the target acquisition time, determine the number of attributes of the same preset location at the target acquisition time.

[0006] Furthermore, the specific method for obtaining the temperature attribute of each preset location at each acquisition time based on the temperature data of all preset locations collected at all acquisition times includes: The average value of all pressure data collected at the target acquisition time is recorded as the average pressure at the target acquisition time; the absolute value of the difference between the temperature data collected by the target temperature sensor at the target acquisition time and the average pressure at the target acquisition time is recorded as the first absolute value of the target temperature sensor at the target acquisition time; and the normalized value of the first absolute value of the target temperature sensor at the target acquisition time is recorded as the temperature deviation of the target temperature sensor at the target acquisition time. When the temperature deviation of the target temperature sensor at the target acquisition time is greater than the preset temperature threshold, the temperature attribute of the target temperature sensor at the target acquisition time is marked as 1; when the temperature deviation of the target temperature sensor at the target acquisition time is less than or equal to the preset temperature threshold, the temperature attribute of the target temperature sensor at the target acquisition time is marked as 0.

[0007] Furthermore, the specific method for determining the number of attributes at the same preset location at the target acquisition time based on the temperature and pressure attributes at the same preset location at the target acquisition time includes: The temperature attribute at the same preset location at the target acquisition time is taken as the least significant bit and the pressure attribute is taken as the most significant bit to determine the number of attributes at the same preset location at the target acquisition time. The number of attributes is a binary value.

[0008] Furthermore, the method for determining the mixing uniformity of the mixing reactor at each sampling time based on the difference in the number of attributes at all the same preset locations within the mixing reactor at adjacent sampling times includes the following specific methods: The difference between the number of attributes at the same preset location at the target acquisition time and the acquisition time preceding the target acquisition time is recorded as the attribute number difference at the same preset location at the target acquisition time. The attribute number differences between adjacent locations at the same preset location at the target acquisition time and the acquisition time preceding the target acquisition time are also recorded. The variance of the difference in the number of attributes at each acquisition time is denoted as the difference in the number of attributes at the target acquisition time for the same preset location, where... Indicates the preset numerical parameters; Based on the differences in the number of attributes at all preset locations of the mixing reactor at the target acquisition time, and the differences in the number of attributes at the target acquisition time and the adjacent acquisition time before the target acquisition time, the first cumulative sum and the second cumulative sum of the mixing reactor at the target acquisition time are determined respectively. The negative correlation between the first and second cumulative sums of the mixing reactor at the target sampling time is denoted as the mixing uniformity of the mixing reactor at the target sampling time.

[0009] Furthermore, the method for determining the first cumulative sum and the second cumulative sum is as follows: The sum of the differences in the number of attributes at all preset positions of the mixing reactor at the target acquisition time is recorded as the first sum of the mixing reactor at the target acquisition time. All preset positions of the mixing reactor adjacent to the target acquisition time and before the target acquisition time will be selected. The sum of the differences in the number of attributes at each acquisition time is denoted as the second sum of the mixed reactor at the target acquisition time.

[0010] Furthermore, the method for obtaining the speed adjustment degree is as follows: The difference in mixing uniformity between the target sampling time and the sampling time immediately preceding the target sampling time is denoted as the mixing uniformity difference of the mixing reactor at the target sampling time; the ratio of the mixing uniformity difference of the mixing reactor at the target sampling time to the average pressure at the target sampling time is denoted as the speed adjustment degree of the mixing reactor at the target sampling time.

[0011] Furthermore, the specific method for determining whether to adjust the rotation speed of the mixing reactor is as follows: When the speed adjustment of the mixing reactor at the target acquisition time is greater than the preset speed adjustment threshold, the speed of the mixing reactor is adjusted; when the speed adjustment of the mixing reactor at the target acquisition time is less than the preset speed adjustment threshold, the speed of the mixing reactor is not adjusted.

[0012] Furthermore, the specific method for controlling the speed of the material mixing process in the mixing reactor based on the speed adjustment degree and the speed of the mixing reactor includes: When the speed adjustment of the mixing reactor at the target acquisition time is greater than the speed adjustment threshold, the sum of the speed adjustment of the mixing reactor at the target acquisition time and the number one is recorded as the first sum of the mixing reactor at the target acquisition time; the product of the first sum of the mixing reactor at the target acquisition time and the speed of the mixing reactor at the target acquisition time is recorded as the ideal speed estimate of the mixing reactor at the target acquisition time; the speed of the mixing reactor is adjusted to the ideal speed estimate of the mixing reactor at the target acquisition time.

[0013] Secondly, another embodiment of this application provides a mixing reactor for the production of black medicine, the mixing reactor being used to implement the steps of the above-described mixing control method for the mixing reactor in the production of black medicine.

[0014] The embodiments of this application have at least the following beneficial effects: When materials are mixed in a mixing reactor, the reaction between the materials is exothermic, generating waste gas and causing variations in temperature and pressure conditions at different locations within the reactor. This leads to uneven mixing of phosphorus pentasulfide and butanol, and localized pressure and temperature anomalies. Therefore, this application determines the attribute number of the same preset location at the same sampling time based on the differences in temperature and pressure data collected from all preset locations at the same sampling time. A higher rotational speed in the mixing reactor results in more vigorous material flow and more pronounced local pressure and airflow fluctuations, leading to greater differences in pressure and airflow fluctuations at different preset locations. Therefore, the mixing performance cannot be evaluated solely based on temperature and pressure deviations at a single preset location at the same sampling time. The degree of uniformity of material mixing within the mixing reactor is not determined solely by temperature and pressure deviations at all preset locations within a continuous time period. This comprehensive assessment determines the mixing uniformity at each sampling point. Then, based on the differences in mixing uniformity between adjacent sampling points and the pressure data from all sampling points at the same sampling point, the rotational speed adjustment of the mixing reactor at each sampling point is obtained. This speed adjustment determines the degree to which the reactor's rotational speed needs adjustment. Based on the speed adjustment and the reactor's rotational speed, the mixing process within the reactor is controlled to prevent issues arising from improper reactor speed settings that could affect the quality of the produced black medicine.

Detailed Implementation

[0017] To further illustrate the technical means and effects adopted by this application to achieve the intended purpose of the invention, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of the mixing reactor and its mixing control method for producing black medicine according to this application. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] The following description, in conjunction with the accompanying drawings, details the specific scheme of the mixing reactor and its mixing control method for the production of black medicine provided in this application.

[0020] Please see Figure 1 The diagram illustrates a flowchart of a mixing control method for a mixing reactor in the production of black medicine according to an embodiment of this application. The method includes the following steps: Step S001: During the mixing process, the rotation speed of the mixing reactor is collected at different sampling times, and pressure and temperature data are collected at different preset positions on the inner wall of the mixing reactor at different sampling times.

[0021] A schematic diagram of the mixing reactor for producing black medicine is shown below. Figure 2 As shown. In Figure 2 In this diagram, 1 represents the motor of the mixing reactor; 2, 4, 8, and 9 represent the locations of the pressure and temperature sensors, which are used to collect pressure and temperature data from the inner wall of the reactor during the mixing process; 3 represents the cooling device for the mixing reactor, used to lower the temperature inside; 5 and 6 together form the agitator, which is controlled by a motor and generates shear force during rotation; 7 represents the heating device for the mixing reactor, used to raise the temperature inside; 10 represents the complete mixing reactor; 11 represents the material storage container for the mixing reactor, which contains liquid ammonia; and 12 represents the exhaust device for the mixing reactor, used for vacuuming and removing impurities from the reaction process. The waste gas, 13, and 14 together form the storage device for the synthetic materials of dibutyl dithiophosphoric acid. In this embodiment, the synthetic materials for dibutyl dithiophosphoric acid are butanol and phosphorus pentasulfide. The heating and cooling devices of the mixing reactor are used together to control the temperature inside the reactor.

[0022] During the operation of the mixing reactor, a vacuum is drawn inside the reactor using an exhaust device. After the vacuum is removed, butanol is added through the dibutyl dithiophosphate synthesis material storage device. The stirring device is then activated to stir the butanol. Phosphorus sulfide is added to the stirred butanol through the dibutyl dithiophosphate synthesis material storage device, and the two begin to react. Simultaneously, the temperature inside the reactor is controlled by cooling and heating modules. After a period of reaction, the waste gas generated during the reaction process is extracted through the exhaust device. At the same time, ammonia gas from the material storage device is introduced into the mixing reactor to mix the material in the mixing reactor with the ammonia gas, thereby obtaining the black powder.

[0023] During the operation of the mixing reactor, pressure and temperature data of the inner wall of the mixing reactor are collected by pressure and temperature sensors, respectively. An electromagnetic speed sensor is installed on the surface of the mixing reactor to collect the rotation speed of the mixing reactor.

[0024] Preferably, in one embodiment of this application, when collecting pressure data, temperature data, and rotational speed, the sampling time interval is 1 second. Pressure sensors and temperature sensors are positioned at preset locations on the inner wall of the mixing reactor at intervals of 10 centimeters. In practical applications, as other implementation methods, the implementer can determine the value of the sampling time interval and the method of preset sensor locations according to the actual situation; this application does not impose any special restrictions.

[0025] Thus, pressure, temperature, and rotational speed data were obtained at different sampling times during the mixing process in the mixing reactor.

[0026] Step S002: Based on the differences in temperature data and pressure data collected at the same time from all preset locations, mark the number of attributes at the same time from the same preset location. Based on the differences in the number of attributes at adjacent times from all the same preset locations in the mixing reactor, determine the mixing uniformity of the mixing reactor at each time from each time.

[0027] During the mixing process in a mixing reactor, reactions occur between the materials. These reactions place specific demands on the temperature, pressure, and dispersion of the materials within the reactor. Therefore, it is necessary to adjust the rotation speed of the mixing reactor to ensure material uniformity and to maintain suitable temperature and pressure conditions at different locations within the reactor for optimal reaction. Specifically, the reactions occurring during mixing in the reactor are exothermic, producing... The exhaust gas will cause changes in temperature and pressure conditions at different locations within the mixing reactor, resulting in uneven mixing of phosphorus pentasulfide and butanol, and abnormal local pressure and temperature.

[0028] Record any acquisition time as the target acquisition time, record any temperature sensor at a preset location as the target temperature sensor, and record the average of all pressure data at the target acquisition time as the average pressure at the target acquisition time. Record the absolute value of the difference between the temperature data acquired by the target temperature sensor at the target acquisition time and the average pressure at the target acquisition time as the first absolute value of the target temperature sensor at the target acquisition time, and record the normalized value of the first absolute value of the target temperature sensor at the target acquisition time as the temperature deviation of the target temperature sensor at the target acquisition time.

[0029] It is understood that in the process of calculating the first absolute value, it is necessary to calculate the difference between the temperature data and the average pressure value. Before calculating the difference, the temperature data and the average pressure value are dimensionless. In this embodiment, the Z-Score standard normalization method is used to perform dimensionless processing on the temperature data and the average pressure value. In practical applications, implementers can use other methods such as the existing technology of maximum and minimum value normalization to perform dimensionless processing, which is not limited here.

[0030] When the temperature deviation of the target temperature sensor at the target acquisition time is greater than the temperature threshold, the temperature attribute of the target temperature sensor at the target acquisition time is marked as 1. A temperature attribute of 1 indicates that the temperature data acquired by the target temperature sensor at the target acquisition time has deviated. When the temperature deviation of the target temperature sensor at the target acquisition time is less than or equal to the temperature threshold, the temperature attribute of the target temperature sensor at the target acquisition time is marked as 0. A temperature attribute of 0 indicates that the temperature data acquired by the target temperature sensor at the target acquisition time has not deviated.

[0031] The temperature threshold is a preset parameter value, and in this embodiment, the temperature threshold is set to 0.68.

[0032] The same method can be used to obtain the temperature attributes of any temperature sensor at any acquisition time.

[0033] Based on the method of obtaining the temperature attribute of any temperature sensor at any acquisition time by using the temperature data collected by all temperature sensors at all acquisition times, the method of obtaining the pressure attribute of any pressure sensor at any acquisition time by using the pressure data collected by all pressure sensors at all acquisition times.

[0034] The temperature attribute at the same preset location at the target acquisition time is taken as the least significant bit and the pressure attribute is taken as the most significant bit, to determine the number of attributes at the same preset location at the target acquisition time.

[0035] It is understandable that since the temperature and pressure attributes take values ​​of 0 or 1, the attribute count is a binary value, with values ​​ranging from 01, 00, 10, to 11. For example, when the temperature attribute of the temperature sensor at a preset location is 0 and the pressure attribute of the pressure sensor is 1 at the target acquisition time, the attribute count at the preset location at the target acquisition time is 10.

[0036] The same method can be used to obtain the number of attributes at any preset location at any collection time.

[0037] The higher the rotational speed of the mixing reactor, the more vigorous the material flow within the reactor, and the more pronounced the local pressure and airflow fluctuations. This also leads to greater differences in pressure and airflow fluctuations at different preset locations. Therefore, the uniformity of material mixing within the mixing reactor cannot be evaluated solely based on the temperature and pressure deviations at a single preset location at the same sampling time. Instead, the uniformity of material mixing should be comprehensively determined based on the temperature and pressure deviations at all preset locations within a continuous time period, thereby identifying whether the rotational speed of the mixing reactor needs to be adjusted.

[0038] The difference between the number of attributes at the same preset location at the target acquisition time and the acquisition time preceding the target acquisition time is recorded as the attribute number difference at the same preset location at the target acquisition time. The attribute number differences between adjacent locations at the same preset location at the target acquisition time and the acquisition time preceding the target acquisition time are also recorded. The variance of the attribute count difference at each acquisition time is denoted as the attribute count stage difference at the target acquisition time for the same preset location. The sum of the attribute count stage differences at all preset locations of the mixing reactor at the target acquisition time is denoted as the first sum of the mixing reactor at the target acquisition time; the sum of the attribute count stage differences at all preset locations of the mixing reactor at and before the target acquisition time is denoted as the first sum of the mixing reactor at the target acquisition time. The sum of the differences in the number of attributes at each sampling time is denoted as the second sum of the mixing reactor at the target sampling time. The negative correlation between the first and second sums of the mixing reactor at the target sampling time is denoted as the mixing uniformity of the mixing reactor at the target sampling time.

[0039] It is understood that a negative correlation is applied to the first and second cumulative sums of the mixing reactor at the target sampling time, ensuring that the first cumulative sum is positively correlated with the mixing uniformity and the second cumulative sum is negatively correlated with the mixing uniformity. It is understood that the negative correlation in this application refers to the relationship between the independent and dependent variables, where the independent variables are the first and second cumulative sums, and the dependent variable is the mixing uniformity. The negative correlation means that the dependent variable decreases (increases) as the independent variable increases (decreases), and can be an inverse relationship, a subtraction relationship, etc.

[0040] Preferably, as an embodiment of this application, the product of the first summation and the second summation of the mixing reactor at the target sampling time is denoted as the first product of the mixing reactor at the target sampling time. The negative of the first product of the mixing reactor at the target sampling time is used as the exponent, and the exponent with the natural constant as the base is used as the power of the exponent, which is denoted as the mixing uniformity of the mixing reactor at the target sampling time.

[0041] in, This represents a preset numerical parameter; in this embodiment, the value of the numerical parameter is 10.

[0042] The mixing uniformity of the mixing reactor at the target sampling time is used to evaluate the deviation of the temperature and pressure of the mixing reactor within a preset time period before the target sampling time.

[0043] The same method can be used to obtain the mixing uniformity of the mixing reactor at any sampling time.

[0044] Thus, the mixing uniformity of the mixing reactor at all sampling times was obtained.

[0045] Step S003: Based on the difference in mixing uniformity between adjacent sampling times and the values ​​of all pressure data of the mixing reactor at the same sampling time, obtain the speed adjustment degree of the mixing reactor at each sampling time, and determine whether to adjust the speed of the mixing reactor. If so, control the speed of the material mixing process in the mixing reactor according to the speed adjustment degree and the speed of the mixing reactor.

[0046] During the operation of the mixing reactor for producing black powder, it is necessary to mix phosphorus pentasulfide and butanol, and also to fuse the materials in the mixing reactor with ammonia. When the rotation speed is too fast, it will affect the mixing effect of liquid and gas, while the pressure will improve the mixing effect of liquid and gas. Therefore, it is necessary to evaluate the deviation of temperature and pressure in the mixing reactor and adjust the rotation speed of the mixing reactor, thereby adjusting the temperature and pressure inside the mixing reactor.

[0047] The difference in mixing uniformity between the target sampling time and the sampling time immediately preceding the target sampling time is denoted as the mixing uniformity difference of the mixing reactor at the target sampling time; the ratio of the mixing uniformity difference of the mixing reactor at the target sampling time to the average pressure at the target sampling time is denoted as the speed adjustment degree of the mixing reactor at the target sampling time.

[0048] Among them, the mixing uniformity difference of the mixing reactor at the target sampling time can be negative. When the mixing uniformity difference of the mixing reactor at the target sampling time is negative, the mixing reactor rotates too fast at the target sampling time, generating a large number of bubbles.

[0049] Mixing can be completed while keeping the rotation speed of the mixing reactor constant at the target acquisition time, but the mixing effect is poor or the mixing time is too long. Therefore, it is necessary to determine whether the rotation speed of the mixing reactor needs to be adjusted based on the speed adjustment degree.

[0050] When the speed adjustment of the mixing reactor at the target acquisition time is greater than the speed adjustment threshold, the speed of the mixing reactor is adjusted to the ideal speed estimate of the mixing reactor at the target acquisition time; when the speed adjustment of the mixing reactor at the target acquisition time is less than the speed adjustment threshold, the speed of the mixing reactor is not adjusted.

[0051] The sum of the speed adjustment of the mixing reactor at the target acquisition time and the number one is recorded as the first sum of the mixing reactor at the target acquisition time; the product of the first sum of the mixing reactor at the target acquisition time and the speed of the mixing reactor at the target acquisition time is recorded as the ideal speed estimate of the mixing reactor at the target acquisition time.

[0052] The speed adjustment threshold is a preset parameter, and in this embodiment, the speed adjustment threshold is set to 0.8.

[0053] At this point, the rotation speed of the material mixing process in the mixing reactor is controlled.

[0054] This application also proposes a mixing reactor for the production of black powder, which is used to implement the above-described steps. Since the mixing control method for the mixing reactor used in the production of black powder has been described in detail above, it will not be repeated here.

[0055] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them; modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
