[0064] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0065] At present, the inventors have found that under some special working conditions, such as too high starting temperature, too fast raw material feeding or non-adiabatic working conditions, if only focusing on the heat release characteristics of the material and ignoring the heat transfer capacity of the reaction vessel, it will not meet the HAZOP analysis principle on the one hand, and on the other hand may lead to too harsh detection process and sacrifice the feasibility of the process. Therefore, how to provide an over-temperature detection method for a reaction vessel has become a technical problem to be solved urgently.

[0066] In order to solve the above technical problems, the embodiments of the present application provide the following technical concepts for solving the problems: first, sort out the possible abnormal working conditions of the reaction container, then perform an adiabatic test on the material in the reaction container, use the heat release characteristic parameters of the material to correct the temperature rise rate of the material, obtain the relationship between the actual temperature rise rate of the material under adiabatic conditions and time, and then calculate the heat release rate and heat transfer rate corresponding to the initial temperature of the material under abnormal working conditions. Then, the temperature rise of the material and the temperature of the reaction container during the residence time of the abnormal working condition are calculated by the heat release rate and the heat transfer rate, and the detection result of whether the reaction container has the hidden danger of overheating is obtained based on the temperature of the reaction container and the pre-designed design temperature.

[0067] Figure 1 A schematic diagram of an application scenario of an over-temperature detection method for a reaction container provided in an embodiment of the present application, such as Figure 1 As shown, it includes: a terminal 101 and a server 102.

[0068] The terminal 101 is used for the test personnel to view the test results, the data changes during the over-temperature detection process, and to issue control instructions. The server 102 is used to receive the parameter or temperature data transmitted from the cloud, other servers or mobile terminals, perform the detection operation, generate the over-temperature detection results and send them to the terminal 101.

[0069] Figure 2 The flowchart of the over-temperature detection method for a reaction container provided in the embodiment of the present application is shown in FIG. Figure 1 The server 102 in the illustrated embodiment may also be other computer-related devices, and there is no particular limitation on this embodiment.

[0070] like Figure 2 As shown, the over-temperature detection method for a reaction container comprises:

[0071] S201: Obtaining initial temperature data and material residence time under various abnormal working conditions corresponding to the reaction container.

[0072] In this embodiment, the reaction vessel can be a container device such as a reactor, a reaction pot, a decomposition pot or a polymerization kettle that provides a physical or chemical reaction space for the material. The initial temperature data under various abnormal working conditions corresponding to the reaction vessel can be determined according to the process characteristics and deviations when the reaction vessel is working, and the initial temperature data under different working conditions are different. For example: 1. The normal preheating temperature of the reaction raw material before the reaction is 50°C. When the preheater fails and the heating power is increased, the preheating temperature can reach 60°C to enter the reactor. At this time, the initial temperature of the abnormal working condition is 60°C; 2. Normal operation is 50°C, the reaction is exothermic, if the heat transfer of the reactor is interrupted, the initial temperature will increase to (normal operating temperature + adiabatic temperature rise of the reaction), and this corresponds to the adiabatic working condition; 3. The operating temperature is 50°C. Under the abnormal working condition of stopping stirring, the initial temperature will not increase and is still 50°C. At this time, the heat transfer capacity of the reaction vessel is normal, corresponding to the non-adiabatic working condition. The material residence time refers to the residence time of the material under abnormal working conditions. Step S201 can be obtained by sorting out data such as relevant parameters of the reaction container when it leaves the factory, which are pre-uploaded and stored from the cloud and the manufacturer's server. These data list as many abnormal operating conditions that the container may encounter and the corresponding design parameters under each abnormal operating condition as possible.

[0073] S202: When the material is subjected to an adiabatic test, the relationship between the temperature and time, the relationship between the temperature rise rate and the temperature, and the starting heat release temperature of the material are obtained.

[0074] In this embodiment, the adiabatic test refers to a test performed on the reaction vessel under adiabatic conditions, which is intended to detect the performance of the reaction vessel when it is isolated from external heat exchange. The temperature-time relationship of the material refers to the relationship between the temperature change over time during the adiabatic test. The temperature rise rate-temperature relationship refers to the relationship between the temperature rise rate and the temperature change. The starting exothermic temperature refers to the temperature corresponding to the starting time point of the exothermic section actually measured during the adiabatic test.

[0075] In this embodiment, when the material is subjected to an adiabatic test, the relationship between the temperature and time of the material, the relationship between the temperature rise rate and the temperature, and the initial exothermic temperature can be acquired through an adiabatic calorimeter, and the test steps of the adiabatic calorimeter are as follows: 1.559g of reaction liquid is weighed as material in a reaction vessel made of high-pressure stainless steel, the "heating-waiting-searching" mode is selected, the temperature step is set to 5°C, the detection sensitivity is 0.02°C / min, the temperature range of the test is 25-190°C, and the mass of the reaction vessel is 11.142g. Then an adiabatic test is performed, and the required data is collected in real time from the start of the test as the initial time, and returned to the execution subject of the method for subsequent steps of over-temperature detection.

[0076] S203: Correction processing is performed according to the relationship between temperature and time, the initial heat release temperature, and the preset basic test parameters to obtain a true temperature rise rate versus time curve of the material under adiabatic conditions.

[0077] In this embodiment, the correction process refers to the process of correcting the temperature rise rate of the heat release section in the adiabatic test of the material by using the relationship between temperature and time, the starting heat release temperature and the preset basic parameters. The preset test basic parameters can be obtained from the data in the operation manual or product manual of the reaction vessel and the initial data set during the actual adiabatic test: for example, the preset test basic parameters can include the maximum operating temperature of the reaction vessel, the type of cooling medium used, the specific heat capacity of the reaction vessel and the mass of the reaction vessel.

[0078] Specifically, the preset test basic parameters include the specific heat capacity of the reaction container, the mass of the reaction container, the specific heat capacity of the material, the mass of the material, the quasi-rate constant, the initial concentration of the reactant, the pre-exponential factor, the pre-stored reaction order and the gas constant; accordingly, in an optional embodiment of the present application, step S203 includes the following steps:

[0079] S203a: Determine the inertia factor according to the specific heat capacity of the reaction container, the mass of the reaction container, the specific heat capacity of the material, and the mass of the material in the preset basic test parameters.

[0080] In an optional embodiment of the present application, the calculation formula for determining the inertia factor in step S203a is:

[0082] In the formula, C p,b is the specific heat capacity of the reaction vessel, m b is the mass of the reaction vessel, C p,s is the specific heat capacity of the material, m s The quality of the material.

[0083] S203b: Determine the activation energy based on the quasi-rate constant, initial concentration of reactants, pre-exponential factor, pre-existing reaction order, gas constant and temperature-time relationship in the preset test basic parameters.

[0087] In this embodiment, the test curve during the adiabatic test is pre-selected to make lnk * The relationship with (1 / T) is linear. If the appropriate reaction order n is selected, the slope of the test curve is the activation energy E.

[0088] S203c: Determine the temperature rise rate during the test based on the relationship between temperature and time.

[0089] In this embodiment, by plotting the relationship between temperature and time and calculating the corresponding slope of the temperature and time curve in the graph, the temperature rise rate during the test can be obtained to represent the value of the temperature rise per unit time during the adiabatic test.

[0090] S203d: Determine the corrected starting exothermic temperature, temperature rise rate and temperature data during the exothermic process according to the gas constant, starting exothermic temperature, temperature rise rate, activation energy and thermal inertia factor in the preset test basic parameters.

[0091] In an optional embodiment of the present application, the calculation formula for determining the corrected starting heat release temperature, temperature rise rate and temperature data during the heat release process in step S203d is:

[0092]

[0093] Where T0 is the starting exothermic temperature, T0′ ,ad is the corrected onset exothermic temperature, is the thermal inertia factor, is the corrected temperature rise rate, T a ' d is the corrected temperature of the entire exothermic process, is the temperature rise rate, E is the activation energy, R is the gas constant, and T is the temperature value determined according to the relationship between temperature and time.

[0094] In this embodiment, the temperature rise rate It refers to the temperature rise rate of the material (sample) and the reaction container system containing the test object during the actual test.

[0095] S203e: Based on the corrected initial exothermic temperature, temperature rise rate and temperature data during the exothermic process, determine the actual temperature rise rate versus time curve of the material under adiabatic conditions.

[0096] In this embodiment, when the material is subjected to an adiabatic test under adiabatic conditions, a curve of the temperature rise rate versus time can be drawn by using the relevant data obtained in steps S203a to S203d.

[0097] S204: Determine the heat release rate corresponding to the material at the initial temperature of the abnormal working condition according to the preset test basic parameters and the actual temperature rise rate versus time curve under the material adiabatic condition.

[0098] In an optional embodiment of the present application, the calculation formula for determining the heat release rate corresponding to the material at the initial temperature of the abnormal operating condition in step S204 is:

[0099]

[0100] In the formula, q rx is the heat release rate of the material at the initial temperature, m is the mass of the material in the reaction vessel, C p is the specific heat capacity of the material, is the temperature rise rate corresponding to the initial temperature.

[0101] From the calculation formula of step S204, it can be seen that:

[0102] S205: Determine the heat transfer rate corresponding to the material at the initial temperature of the abnormal working condition according to the preset test basic parameters and the actual temperature rise rate versus time curve under the material adiabatic condition.

[0103] Based on the above embodiment, in an optional embodiment of the present application, the preset test basic parameters also include the preset material reaction temperature of the abnormal working condition, the preset cooling medium temperature, the heat transfer coefficient and the heat transfer area; accordingly, the calculation formula for determining the heat transfer rate corresponding to the material at the initial temperature of the abnormal working condition in step S205 is:

[0104] q ex =US(T A -T0)

[0105] In the formula, q ex is the heat transfer rate of the material at the initial temperature, U is the heat transfer coefficient, S is the heat transfer area, T A is the preset material reaction temperature under abnormal working conditions, and T0 is the preset cooling medium temperature.

[0106] In this embodiment, the preset material reaction temperature of abnormal working conditions can be the original parameter of the reaction vessel when it is produced and shipped, which refers to the standard temperature of the material reaction in the reaction vessel under abnormal working conditions. The preset cooling medium temperature refers to the temperature of the cooling medium required to be used determined according to the different operating conditions of the reaction vessel, the properties of the reacted materials and the temperature control requirements to be achieved. For example: when the internal temperature of the reaction vessel is lower than 60°C, cooling water can be used as the cooling medium, and the preset cooling medium temperature at this time can be 55°C.

[0107] In this embodiment, it can be seen from step S204 and step S205 that these abnormal operating conditions have heat transfer rate and heat release rate corresponding to the material, which means that the over-temperature detection method for the reaction container provided in the embodiment of the present application can be used to detect whether the reaction container is over-temperature under non-adiabatic conditions.

[0108] S206: When it is detected that the heat transfer rate is less than or equal to the heat release rate, the temperature rise of the material during the residence time of the abnormal operating condition is determined according to the heat release rate and the heat transfer rate, the preset basic test parameters and the temperature and time relationship of the material when the material is subjected to an adiabatic test, and the final temperature of the reaction vessel is determined according to the temperature rise of the material during the residence time of the abnormal operating condition.

[0109] In an optional embodiment of the present application, in step S206, according to the heat release rate and heat transfer rate, the preset basic test parameters and the temperature and time relationship of the material obtained when the material is subjected to an adiabatic test, the calculation formula for determining the temperature rise of the material during the residence time of the abnormal working condition is:

[0110]

[0111] In the formula, C p is the specific heat capacity of the material, m is the mass of the material in the reaction vessel, T a ' d is the corrected temperature of the entire exothermic process, T0′ ,ad is the corrected starting exothermic temperature, T and t can be respectively determined based on the temperature and time relationship of the material obtained during the adiabatic test of the material. The temperature and time relationship is plotted, and the temperature rise during the residence time is read from the graph to calculate the final temperature of the reaction vessel.

[0112] In an optional embodiment of the present application, in step S206, the final temperature of the reaction container is determined according to the temperature rise of the material during the residence time of the abnormal operating condition, and the calculation formula is:

[0113] T A,f =T A,0 +ΔT

[0114] Where, T A,f is the final temperature of the reaction vessel under abnormal conditions, T A,0 is the initial temperature of the reaction vessel under abnormal conditions, and ΔT is the temperature rise of the material during the residence time of the reaction vessel under abnormal conditions.

[0115] S207: When it is detected that the final temperature of the reaction container is higher than the pre-stored design temperature, a first over-temperature detection result is generated, indicating that the reaction container has a potential over-temperature risk.

[0116] In this embodiment, the pre-stored design temperature refers to the temperature value pre-specified when the reaction container leaves the factory. The temperature value may be the highest operating temperature that the reaction container can withstand. For example, the pre-stored design temperature of a glass distillation flask is 200°C.

[0117] In this embodiment, the generated first over-temperature detection result may be feedback information such as text description, voice, numerical value or chart that can indicate that the reaction container has a potential over-temperature risk.

[0118] In an optional embodiment of the present application, the over-temperature detection method for a reaction container further includes:

[0119] Step A: When it is detected that the heat removal rate is greater than or equal to the heat release rate, a second over-temperature detection result indicating that the reaction container is safe is generated.

[0120] In this embodiment, the generated second over-temperature detection result may be feedback information in the form of text description, voice, numerical value or chart, etc., which can indicate that the reaction container has no risk of over-temperature.

[0121] In order to facilitate the understanding of the content of the above method embodiment, the present application embodiment also provides an example of using the over-temperature detection method for a reaction container provided in the above embodiment to perform over-temperature detection, as follows:

[0122] Assume that the volume of a reaction vessel is 500L, the pre-stored design temperature is 150℃, the operating temperature is 35℃, the heat is transferred by external circulation, the mass of the material is 1.559g, and the mass of the reaction vessel is 11.142g. Under the condition that the catalyst feed rate of the reaction vessel is too fast, the main reaction is accelerated and the temperature rises to 110℃. At this time, it is necessary to evaluate whether the reaction vessel is overheated during the reaction process.

[0123] Figure 3 This is a schematic diagram of the relationship between temperature and time of the material provided in the embodiments of the present application.

[0124] Figure 4 A schematic diagram of the relationship between the temperature rise rate and temperature provided in an embodiment of the present application.

[0125] Figure 5 A schematic diagram of the relationship between the corrected temperature rise rate and temperature provided in an embodiment of the present application.

[0126] In this example, the temperature and time relationship, temperature rise rate and temperature relationship, and starting exothermic temperature of the material obtained by the adiabatic test are as follows: for example, the starting temperature of the material is 105°C, and the adiabatic temperature rise is 150°C. The data obtained by the adiabatic test can be automatically drawn into a corresponding test curve using drawing software in the server 102, such as Figure 3 and Figure 4 As shown, the starting temperature is 105°C. At this time, according to:

[0127]

[0128] It can be calculated is 2.5. According to:

[0129]

[0130] The fitting results show that n is 1.16 and E is 115080 J / mol.

[0131]

[0132] The relationship between the corrected temperature rise rate and temperature is shown in Figure 3 , the temperature rise rate at 110℃ is 0.1K / min. The specific heat capacity of the material is 22kJ / (kg·K), the mass of the reaction liquid in the reaction container is 2t, according to

[0133]

[0134] The heat release rate of the reaction liquid is 800w. According to the inventor's practice, the heat transfer capacity of the reactor is 2000w. The heat transfer power of the reaction container at 110°C is greater than the heat release power. The secondary reaction of the material will not cause the temperature of the reaction container to continue to rise. Therefore, the first over-temperature detection result that will not cause the reaction container to overheat is generated for the inspector to review.

[0135] In summary, the over-temperature detection method for a reaction vessel provided in the embodiment of the present application first obtains the initial temperature data and the material residence time under various abnormal working conditions corresponding to the reaction vessel, and then obtains the temperature and time relationship, the temperature rise rate and temperature relationship, and the initial heat release temperature of the material when the material is subjected to an adiabatic test. Then, a correction process is performed to obtain the true temperature rise rate over time curve of the material under adiabatic conditions, and then determine the heat release rate corresponding to the initial temperature material of the abnormal working condition. Then determine the heat transfer rate corresponding to the initial temperature material of the abnormal working condition to achieve the purpose of obtaining the corresponding test data under non-adiabatic working conditions. Then, when it is detected that the heat transfer rate is less than or equal to the heat release rate, the temperature and time relationship of the material is obtained according to the heat release rate and the heat transfer rate, the preset basic test parameters, and the adiabatic test of the material, and the temperature rise of the material during the residence time of the abnormal working condition is determined, and then the final temperature of the reaction vessel is determined. When it is detected that the final temperature of the reaction vessel is higher than the pre-stored design temperature, the first over-temperature detection result indicating that the reaction vessel has an over-temperature hazard is generated. Therefore, the present application can not only ensure the severity of over-temperature detection without sacrificing the process, but also quickly check whether the reaction container has over-temperature risks under adiabatic conditions, and can also check whether the reaction container has over-temperature risks under non-adiabatic conditions.
