Description

Technical Field

[0001] The present invention relates to the field of industrial production technology, and in particular to a method, device, equipment and medium for controlling production load and temperature of multiple reactors. Background Art

[0002] R142b, also known as monochlorodifluoroethane, has a chemical formula of C2H2ClF2. It can be used as a raw material for high-performance functional fluorinated polymer PVDF (polyvinylidene difluoride). It is also mainly used as a refrigerant, foaming agent, intermediate for producing vinylidene fluoride, temperature controller medium and aviation propellant. It is a type of Freon product and belongs to hydrochlorofluorocarbons. It is one of the important chemical raw materials. In the actual production process of R142b, since the R142b load is affected by downstream devices, there are often conditions where the production load is frequently adjusted. Due to the limitation of manual operation capabilities, the use of multiple reactors will increase a large amount of manual operation load and potential risks of accidents. There is an urgent need for a technical means to automatically control the load distribution of multiple reactors and the temperature control of reactors. Summary of the invention

[0031] If there is a reactor to be deactivated, the reactor to be currently deactivated is determined according to the reactor to be deactivated, and the process jumps again to the step of determining whether the reactor to be currently deactivated needs to perform multiple load reduction operations based on historical data;

[0032] If there is no reactor to be deactivated, the process jumps again to the step of allocating the load components to be reduced of each reactor based on the preset load reduction threshold.

If so, the current operating condition of the reactor is determined according to the current load of the reactor and the preset load. If the current operating condition is the preset load lifting condition, the load to be lifted is used to determine whether to start a new reactor, and the reactor to be currently loaded is determined according to the corresponding first judgment result. Based on historical data, it is determined whether the reactor to be currently loaded needs to perform multiple load lifting operations to obtain a second judgment result. Then, according to the second judgment result, the reactor to be currently loaded is controlled to perform the corresponding load lifting operation until the current load of the reactor is equal to the preset load, and the operation is re-executed. The steps of identifying and controlling the hot spot temperature and buffer tank pressure of the reactor; if the current working condition is the preset load reduction working condition, the load to be reduced is used to determine whether there is a reactor to be deactivated, the reactor to be currently loaded is determined according to the corresponding third judgment result, and whether the reactor to be currently loaded needs to perform multiple load reduction operations based on historical data, and a fourth judgment result is obtained; then, the reactor to be currently loaded is controlled to perform the corresponding load reduction operation according to the fourth judgment result, until the current load of the reactor is equal to the preset load, and the steps of identifying and controlling the hot spot temperature and buffer tank pressure of the reactor are re-executed; finally, in the process of performing the load increase operation or the load reduction operation on the reactor, the temperature of the reactor is controlled based on the target spray regulating valve of each reactor. It can be seen that the present application determines the load lifting control and temperature control step by step through a series of judgments, performs different operations under different circumstances, realizes cyclic control of the load lifting control process, and effectively reduces the time and operation frequency of manual judgment. At the same time, spray protection control is established, which greatly reduces the risk of high temperature in the reactor during the load lifting process, ensures the stability of the device production and reduces the risk.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] At present, in view of the problems of production load control and temperature control of multiple R142b reactors, the production workshop generally adopts manual adjustment of production load and temperature, that is, high-frequency operation is performed on multiple reactors, the feed of multiple reactors is changed, and the reaction cooling unit is adjusted to adjust the hydrochloric acid spraying amount, or a new reactor is opened or a reactor is stopped to adapt to the changed load. Manual adjustment of production load and temperature is cumbersome, difficult to operate, long operation time, extensive operation, prone to error, poor safety, easy to cause the back-end reaction cooling system to be handled in time, and the operation methods of each team are not unified. And because the production device generally includes multiple reactors in parallel production, improper handling of a single reactor may cause the distillation unit at the rear end of the reaction to fluctuate, affecting the quality of the final product. In order to solve the above-mentioned technical problems, the present application discloses a method, device, equipment and medium for controlling production load and temperature of multiple reactors, which can realize automatic control of the lifting load and temperature of multiple reactors, and effectively reduce the time and operation frequency of manual judgment.

[0053] See also Figure 1 As shown, the embodiment of the present invention discloses a method for controlling production load and temperature of a multi-branch reactor, comprising:

[0054] Step S11, determine whether the load lifting confirmation switch is turned on. If not, identify and control the hot spot temperature of the reactor and the pressure of the buffer tank. If so, determine the current operating condition of the reactor based on the current load of the reactor and the preset load.

[0055] In this embodiment, after the load lifting module is started, the present application first confirms whether the load lifting confirmation switch is turned on. If the load lifting confirmation switch is not turned on, that is, no load lifting operation is required, the corresponding reactor hot spot temperature and buffer tank pressure are automatically identified, and the reactor hot spot temperature setting value T and buffer tank pressure P are automatically controlled. If the load lifting confirmation switch is turned on, it is necessary to determine whether the current working condition of the reactor is to increase or decrease the load according to the current load of the reactor and the preset load.

[0056] Step S12: If the current operating condition is a preset load increase condition, the load to be increased is used to determine whether to start a new reactor, the reactor to be currently loaded is determined according to the corresponding first judgment result, and based on historical data, it is determined whether the reactor to be currently loaded needs to perform multiple load increase operations to obtain a second judgment result.

[0057] In the present embodiment, the number of reactors participating in the control, the hot spot temperature threshold of the reactor and the preset load are first determined by the input information of the staff. If the preset load is higher than the current load, it is determined to be a load increase. At this time, the load to be increased is used to determine whether to start a new reactor, and the reactor to be currently loaded is determined according to the corresponding first judgment result. That is, after clicking the load increase confirmation button, the load increase is used to automatically determine whether a new reactor is needed. If a new reactor is started, the new reactor is determined as the reactor to be currently loaded. At the same time, the hydrochloric acid spray regulating valve of this reactor is opened by itself (if multiple units, 1 unit is opened in sequence first), and the corresponding feed valve is opened 5 minutes after the hydrochloric acid spray regulating valve is opened. If a new reactor is not started, each reactor participating in the control is determined as the reactor to be currently loaded. Then the historical data is used to calculate whether the reactor to be currently loaded needs to be loaded multiple times.

[0058] Step S13, according to the second judgment result, control the reactor to be loaded to perform the corresponding load increase operation until the current load of the reactor is equal to the preset load, and re-execute the steps of identifying and controlling the hot spot temperature of the reactor and the pressure of the buffer tank.

[0059] In the present embodiment, if the current reactor to be loaded needs to perform a load-raising operation, the current reactor to be loaded is directly controlled to perform the load-raising operation based on the load to be raised. That is, when only one load-raising operation is needed, the remaining load is directly raised in full. If the new reactor needs to perform multiple load-raising operations, the new reactor is controlled to perform the load-raising operation based on the preset load-raising threshold and the preset timing time, and after the timing ends, it is judged again whether the new reactor needs to perform multiple load-raising operations until the new reactor needs to perform a load-raising operation. Specifically, if multiple load-raising operations are required, the load is raised by 50kg each time, and the timing is 10 minutes. The reactor temperature is automatically adjusted by spraying hydrochloric acid to avoid raising the load too quickly, resulting in temperature rise. After the timing ends, it is judged again whether the load-raising amount needs to be raised and lowered multiple times. The above operation is repeated until it is judged that only one load-raising operation is needed, and the remaining load is fully raised. And if the load of the new reactor rises to the target value, it is determined whether to start the new reactor based on the remaining load increase amount; if the new reactor is started, the reactor to be loaded is determined based on the new reactor, and the process jumps back to the step of determining whether the reactor to be loaded needs to perform multiple load increase operations based on historical data; if the new reactor is not started, the process jumps back to the step of allocating the load components to be increased to each reactor based on the preset load increase threshold. That is, if the load of the new reactor rises to the same level as the reactor with the lowest load at present, it is determined again whether the remaining load increase amount requires a new reactor to be opened. If a new reactor is still required, the reactor to be loaded is determined based on the new reactor, and the process jumps back to the step of determining whether the reactor to be loaded needs to perform multiple load increase operations based on historical data; if it is determined that a new reactor is not required, the process jumps back to the step of allocating the load components to be increased to each reactor based on the preset load increase threshold, so as to realize load increase cycle control.

[0060] At the same time, if each reactor involved in the control needs to perform multiple load raising operations, the load component to be raised of each reactor is allocated based on the preset load raising threshold, and each reactor is controlled to perform the load raising operation by the load component to be raised and the preset timing time, and after the timing ends, it is judged again whether each reactor needs to perform multiple load raising operations until each reactor needs to perform a load raising operation. In other words, if the m reactors involved in the control need to raise and lower the load multiple times, the load is raised by 50kg each time, and the m reactors automatically allocate the load raising amount, and the timing is 10 minutes. Hydrochloric acid spray is used to adjust the temperature of the m reactors to avoid raising the load too quickly, which causes temperature rise. After the timing ends, it is judged again whether the load raising amount needs to be raised multiple times, and the above operation is repeated until only one load raising is required, and the remaining load is fully raised. It should be pointed out that in the overall process of load increase, the m reactors automatically adjust the corresponding hydrochloric acid spray and continuously control the reactor temperature. After the hydrochloric acid spray reaches the spray upper limit, the corresponding reactor load is automatically reduced and distributed to the remaining reactors. At the same time, in the process of load increase, the pressure of the buffer tank is controlled to be stable to avoid the pressure of the buffer tank being too high or too low. After reaching the set load, the load increase is completed and the process returns to the step of determining whether the load lifting confirmation switch is turned on, thereby realizing the overall automatic cycle control of the load lifting module.

[0061] Step S14: If the current operating condition is a preset load reduction condition, the load to be reduced is used to determine whether there is a reactor to be deactivated, the reactor to be currently loaded with load reduction is determined according to the corresponding third judgment result, and based on historical data, it is determined whether the reactor to be currently loaded with load reduction needs to perform multiple load reduction operations to obtain a fourth judgment result.

[0062] In this embodiment, if the preset load is lower than the current load, it is determined to be a load reduction, that is, the current operating condition is a preset load reduction condition, and then the load to be reduced is used to determine whether there is a reactor to be deactivated. After clicking the load increase and decrease confirmation button, it is automatically determined whether there is a reactor that needs to be deactivated. If there is a reactor to be deactivated, the reactor to be deactivated is determined as the reactor to be currently deactivated; if there is no reactor to be deactivated, each reactor involved in the control is determined as the reactor to be currently deactivated. Afterwards, it is determined based on historical data whether the reactor to be currently deactivated needs to perform multiple load reduction operations.

[0063] Step S15, according to the fourth judgment result, control the reactor to be loaded down to perform the corresponding load reduction operation until the current load of the reactor is equal to the preset load, and re-execute the steps of identifying and controlling the hot spot temperature of the reactor and the pressure of the buffer tank.

[0064] In this embodiment, after judging whether the reactor to be deactivated needs to perform multiple load reduction operations based on historical data, if the reactor to be deactivated needs to perform multiple load reduction operations, the reactor to be deactivated is controlled to perform the load reduction operation based on the preset load reduction threshold and the preset timing time, and after the timing ends, it is judged again whether the reactor to be deactivated needs to perform multiple load reduction operations, until the reactor to be deactivated needs to perform a load reduction operation to reduce the load of the reactor to be deactivated to zero. Specifically, if the deactivation reactor needs multiple load reductions, the load is reduced by 50kg each time, and the timing is 10 minutes. Hydrochloric acid spray is used to adjust the reactor temperature to avoid too fast load reduction, which leads to insufficient reaction. After the timing ends, it is judged again whether the load reduction amount needs multiple load reductions, and the above operations are repeated until only one load reduction is required and the load of the reactor can be reduced to 0. If the load of the reactor to be deactivated drops to zero, it is re-determined whether there is a reactor to be deactivated; if there is a reactor to be deactivated, the reactor to be currently deactivated is determined based on the reactor to be deactivated, and the process is re-judged to determine whether the reactor to be currently deactivated needs to perform multiple load reduction operations based on historical data; if there is no reactor to be deactivated, the process is re-judged to allocate the load components to be deactivated to each reactor based on the preset load reduction threshold, thereby realizing load reduction cycle control.

[0065] At the same time, if each reactor involved in the control needs to perform multiple load reduction operations, the load components to be reduced of each reactor are allocated based on the preset load reduction threshold, and each reactor is controlled to perform the load reduction operation by the load components to be reduced and the preset timing time, and after the timing is over, it is judged again whether each reactor needs to perform multiple load reduction operations until each reactor needs to perform a load reduction operation. Specifically, whether the m-branch reactor needs to lift and lower the load multiple times, and if it needs to lift and lower the load multiple times, then the load is reduced by 50kg each time, and the m-branch reactor automatically allocates the load reduction amount, and the timing is 10 minutes. The m-branch reactor corresponds to the hydrochloric acid spray and automatically adjusts, and the reactor temperature is continuously controlled to avoid the load reduction being too fast, resulting in insufficient reaction. After the timing is over, it is judged again whether the load reduction amount needs to be reduced multiple times, and the above operation is repeated until only one load reduction is required, and the remaining load amount is completely reduced. In the overall process of lifting and lowering the load, the hydrochloric acid spray will continue to control the reactor temperature. In the process of reducing the load, the pressure of the buffer tank is controlled to be stable at the same time to avoid the pressure of the buffer tank being too high or too low. After it drops to the set load, the load reduction ends, and it returns to the step of judging whether the lifting and lowering load confirmation switch is turned on, and the load reduction automatic cycle control is realized.

[0066] In this embodiment, if the reactor to be currently loaded with load reduction needs to perform a load reduction operation, the reactor to be currently loaded with load reduction is directly controlled to perform the load reduction operation based on the load amount to be reduced.

[0067] Step S16: Controlling the temperature of the reactor based on the target spray regulating valve of each reactor during the load increase operation or the load decrease operation of the reactor.

[0068] In this embodiment, during the whole process of lifting and lowering the load, the hydrochloric acid spray will continue to control the reactor temperature. For example, during the process of lifting the load, if the amount of hydrochloric acid sprayed by a reactor is too large, the load of this reactor will be automatically reduced, and the load will be distributed to (m-1) reactors. In this way, by establishing the hydrochloric acid spray protection control, the risk of high temperature of the reactor during the process of lifting and lowering the load is greatly reduced, ensuring the stability of the device production and reducing the risk. In addition, in the process of controlling the production load and temperature of the reactor, if the hot spot temperature of the reactor is greater than the preset temperature threshold or the pressure of the buffer tank is greater than the preset pressure threshold, a voice alarm will be issued. Specifically, when the load is automatically lifted, a voice alarm will pop up, "Start lifting and lowering the load", if a new reactor needs to be opened, "This time the load needs to be lifted and lowered, a new reactor will be opened, and the minimum load will be reached. The new reactor will pop up, "The new reactor has reached the minimum load, and the load will continue to be lifted and lowered", and the new reactor needs to be stopped. "This time the load needs to be stopped". After the reactor stops, "One reactor has been stopped" pops up, and when the load lifting is over, "This time the load lifting has ended" pops up. In the overall process, if the temperature is too high or the pressure is too high, a voice alarm "The reactor temperature is high" or "The reactor pressure is high" will pop up. At the same time, the reactor being reported is a specific reactor. Through the configured voice alarm function, when the conditions are not met or abnormal conditions occur and the program running conditions cannot be met, voice reminders or program execution will be suspended, which not only ensures the safety of operation but also reduces the risk of slow manual intervention.

[0069] To sum up, when controlling the production load and temperature of multiple reactors, the present application first determines whether the load lifting confirmation switch is turned on. If not, the hot spot temperature of the reactor and the buffer tank pressure are identified and controlled. If so, the current operating condition of the reactor is determined according to the current load of the reactor and the preset load. If the current operating condition is the preset load lifting condition, the load to be lifted is used to determine whether to start a new reactor, and the reactor to be currently loaded is determined according to the corresponding first judgment result. Based on historical data, it is determined whether the reactor to be currently loaded needs to perform multiple load lifting operations to obtain a second judgment result. Then, according to the second judgment result, the reactor to be currently loaded is controlled to perform the corresponding load lifting operation until the current load of the reactor is equal to the preset load, and the operation is re-executed. The step of identifying and controlling the hot spot temperature and buffer tank pressure of the reactor; if the current working condition is a preset load reduction working condition, the load to be reduced is used to determine whether there is a reactor to be deactivated, the reactor to be reduced is determined according to the corresponding third judgment result, and the reactor to be reduced is determined based on historical data whether multiple load reduction operations need to be performed to obtain a fourth judgment result; then the reactor to be reduced is controlled to perform the corresponding load reduction operation according to the fourth judgment result until the current load of the reactor is equal to the preset load, and the step of identifying and controlling the hot spot temperature and buffer tank pressure of the reactor is re-executed; finally, in the process of performing the load increase operation or the load reduction operation on the reactor, the temperature of the reactor is controlled based on the target spray regulating valve of each reactor. It can be seen that the present application determines the load lifting control and temperature control step by step through a series of judgments, performs different operations under different circumstances, realizes cyclic control of the load lifting control process, and effectively reduces the time and operation frequency of manual judgment. At the same time, spray protection control is established, which greatly reduces the risk of high temperature in the reactor during the load lifting process, ensures the stability of the device production and reduces the risk.

[0070] Based on the previous embodiment, the present application discloses a method for controlling the production load and temperature of multiple reactors, which can control the reactors under different conditions to perform different operations, realize cyclic automatic control of the lifting load control process, and effectively reduce the time and operation frequency of manual judgment. Next, the control process of the production load and temperature of the reactor under different conditions will be described in detail.

[0071] In the operating environment of load lifting control of multiple reactors (Advanced Process Control software (APC (Advanced Process Control) software), the load lifting module is divided into two major working conditions, normal working conditions and load lifting working conditions. In the load lifting working condition, it is further subdivided into load raising working conditions and load lowering working conditions, so as to realize automatic determination from normal working conditions to load lifting working conditions, automatic selection of reactor start and stop, and cycle control of returning to normal working conditions after the load lifting working condition ends, as well as overall control of the reactor temperature by the hydrochloric acid spraying amount during the overall load lifting process. The specific various working conditions are as follows.

[0072] Working condition 1: After the load lifting module is started, the load lifting confirmation switch is not turned on, that is, no load lifting operation is required. The corresponding reactor hot spot temperature and buffer tank pressure are automatically identified, and the reactor hot spot temperature setting value T and buffer tank pressure P are automatically controlled.

[0073] Working condition two: The load lifting confirmation switch is turned on, and load lifting operations are required. First, manually confirm that the m reactors are initially given to participate in the control, the reactor set temperature T, and the load lifting setting value F. If the set load is higher than the current load, it is determined to be a load lifting condition. After clicking the load lifting confirmation button, the load increase is used to automatically determine whether a new reactor needs to be started. If it is determined that a new reactor needs to be started, open the hydrochloric acid spray regulating valve of this reactor automatically (if there are multiple reactors, open one in sequence first). After opening the hydrochloric acid spray regulating valve for 5 minutes, open the corresponding feed valve, and use historical data to calculate whether the new reactor needs to increase the load multiple times. If multiple load increases are required, the load is increased by 50kg each time, and the timing is 10 minutes. The hydrochloric acid spray is automatically used to adjust the reactor temperature to avoid increasing the load too quickly, which will cause temperature rise. After the timing ends, it is determined again whether the reactor needs to be lifted. Check whether the load needs to be raised or lowered multiple times, repeat the above operation until it is determined that only one load increase is needed, and then all the remaining load will be increased. During the entire process of load increase, the hydrochloric acid spray will continue to control the reactor temperature. After the load reaches the set load, the load increase is completed and the system returns to operating condition one to achieve automatic cycle control of the load increase module as a whole. If the load increases to the same level as the current minimum load reactor, return to operating condition one to determine whether the remaining load increase requires a new reactor to be opened. If a new reactor is still required, repeat operating condition two. If it is determined that a new reactor is not needed, jump to operating condition three to achieve load increase cycle control.

[0074] Working condition three: using the load increase, the program automatically determines that there is no need to open a new reactor, and automatically calculates through historical data whether the m reactors involved in the control need to increase or decrease the load multiple times. If multiple load increases are required, the load is increased by 50kg each time, and the m reactors automatically distribute the load increase. The timing is 10 minutes, and the temperature of the m reactors is adjusted by hydrochloric acid spraying to avoid increasing the load too quickly and causing temperature rise. After the timing ends, it is determined again whether the load increase requires multiple load increases. Repeat the above operation until only one load increase is required, and the remaining load is increased. During the overall process of load increase, the m reactors automatically adjust the corresponding hydrochloric acid spray to continuously control the reactor temperature. After the hydrochloric acid spray reaches the spray upper limit, the corresponding reactor load is automatically reduced and distributed to the remaining reactors. At the same time, during the load increase process, the pressure of the buffer tank is controlled to be stable to avoid the pressure of the buffer tank being too high or too low. After reaching the set load, the load increase ends and returns to working condition one to achieve overall automatic cycle control of the load lifting module.

[0075] Working condition 4: First, manually confirm the initial given m reactors participating in the control, the reactor set temperature T, and the lifting load set value F. If the set load is lower than the current load, it is determined to be a load reduction. After clicking the lifting load confirmation button, it is automatically determined whether there is a reactor that needs to be deactivated. If there is a reactor that needs to be deactivated, the load reduction will start automatically. The historical data is used to calculate whether the deactivation of the reactor requires multiple load reductions. If multiple load reductions are required, the load is reduced by 50kg each time, and the timing is 10 minutes. Hydrochloric acid spray is used to adjust the reactor temperature to avoid excessive load reduction, resulting in insufficient reaction. After the timing ends, it is determined again whether the load reduction amount requires multiple load reductions. Repeat the above operations until only one load reduction is required or the reactor load is reduced to 0. During the overall load reduction process, hydrochloric acid spray will continue to control the reactor temperature. After it drops to the set load, the load reduction ends and returns to working condition 1 to achieve the overall automatic cycle control of the lifting load module; if the load of a single reactor has dropped to 0, return to working condition 1 to determine the conditions. If there is still a need to stop the reactor, repeat the operation of working condition 2. If there is no reactor to be stopped, jump to working condition 5 to achieve load reduction cycle control.

[0076] Working condition five: automatically judge whether there is no need to stop the reactor, calculate through historical data whether the m reactors need to raise and lower the load multiple times, if multiple times are needed, then reduce the load by 50kg each time, and the m reactors automatically allocate the load reduction amount, and time for 10 minutes. The m reactors automatically adjust the corresponding hydrochloric acid spray, and continuously control the reactor temperature to avoid reducing the load too quickly, resulting in insufficient reaction. After the timing ends, judge again whether the load reduction amount needs multiple load reductions, repeat the above operation until only one load reduction is needed, and reduce the remaining load. In the whole process of lifting and lowering the load, the hydrochloric acid spray will continuously control the reactor temperature. In the process of load reduction, the pressure of the buffer tank is controlled to be stable at the same time to avoid the pressure of the buffer tank being too high or too low. After it drops to the set load, the load reduction ends and returns to working condition one to achieve automatic cycle control of load reduction.

[0077] As a result, the load lifting control process is implemented in a cycle control, effectively reducing the time and frequency of manual judgment. At the same time, spray protection control is established to greatly reduce the risk of high temperature in the reactor during the load lifting process, ensuring the stability of the device production and reducing risks.

[0078] See also Figure 2 As shown, the embodiment of the present invention discloses a production load and temperature control device for multiple reactors, comprising:

[0079] The working condition determination module 11 is used to determine whether the load lifting confirmation switch is turned on. If not, the hot spot temperature of the reactor and the pressure of the buffer tank are identified and controlled. If yes, the current working condition of the reactor is determined according to the current load of the reactor and the preset load.

[0080] The second judgment result acquisition module 12 is used to determine whether to start a new reactor based on the load to be increased if the current working condition is a preset load increase working condition, determine the reactor to be currently loaded according to the corresponding first judgment result, and determine whether the reactor to be currently loaded needs to perform multiple load increase operations based on historical data to obtain a second judgment result;

[0081] A first jump module 13 is used to control the reactor to be loaded at present to perform the corresponding load-increasing operation according to the second judgment result, until the current load of the reactor is equal to the preset load, and re-execute the step of identifying and controlling the hot spot temperature of the reactor and the pressure of the buffer tank;

[0082] The fourth judgment result acquisition module 14 is used to determine whether there is a reactor to be deactivated by using the load to be reduced if the current working condition is a preset load reduction working condition, determine the reactor to be currently loaded with reduced load according to the corresponding third judgment result, and determine whether the reactor to be currently loaded with reduced load needs to perform multiple load reduction operations based on historical data to obtain a fourth judgment result;

[0083] The second jump module 15 is used to control the reactor to be loaded at present to perform the corresponding load reduction operation according to the fourth judgment result, until the current load of the reactor is equal to the preset load, and re-execute the step of identifying and controlling the hot spot temperature of the reactor and the pressure of the buffer tank;

[0084] The temperature control module 16 is used to control the temperature of the reactor based on the target spray regulating valve of each reactor during the process of performing the load increase operation or the load decrease operation on the reactor.

[0085] To sum up, when controlling the production load and temperature of multiple reactors, the present application first determines whether the load lifting confirmation switch is turned on. If not, the hot spot temperature of the reactor and the buffer tank pressure are identified and controlled. If so, the current operating condition of the reactor is determined according to the current load of the reactor and the preset load. If the current operating condition is the preset load lifting condition, the load to be lifted is used to determine whether to start a new reactor, and the reactor to be currently loaded is determined according to the corresponding first judgment result. Based on historical data, it is determined whether the reactor to be currently loaded needs to perform multiple load lifting operations to obtain a second judgment result. Then, according to the second judgment result, the reactor to be currently loaded is controlled to perform the corresponding load lifting operation until the current load of the reactor is equal to the preset load, and the operation is re-executed. The step of identifying and controlling the hot spot temperature and buffer tank pressure of the reactor; if the current working condition is a preset load reduction working condition, the load to be reduced is used to determine whether there is a reactor to be deactivated, the reactor to be reduced is determined according to the corresponding third judgment result, and the reactor to be reduced is determined based on historical data whether multiple load reduction operations need to be performed to obtain a fourth judgment result; then the reactor to be reduced is controlled to perform the corresponding load reduction operation according to the fourth judgment result until the current load of the reactor is equal to the preset load, and the step of identifying and controlling the hot spot temperature and buffer tank pressure of the reactor is re-executed; finally, in the process of performing the load increase operation or the load reduction operation on the reactor, the temperature of the reactor is controlled based on the target spray regulating valve of each reactor. It can be seen that the present application determines the load lifting control and temperature control step by step through a series of judgments, performs different operations under different circumstances, realizes cyclic control of the load lifting control process, and effectively reduces the time and operation frequency of manual judgment. At the same time, spray protection control is established, which greatly reduces the risk of high temperature in the reactor during the load lifting process, ensures the stability of the device production and reduces the risk.
