Description

Technical Field

[0001] This invention relates to the field of pressure vessel technology, and in particular to a method for steam transfer from an autoclave, a control device, electronic equipment, and a storage medium. Background Technology

[0002] An autoclave is a large and heavy pressure vessel. Autoclaves are widely used for the autoclaving of building materials such as aerated concrete blocks, concrete pipe piles, sand-lime bricks, fly ash bricks, microporous calcium silicate boards, new lightweight wall materials, thermal insulation asbestos boards, and high-strength gypsum.

[0003] Existing technology typically involves introducing steam into an autoclave via a boiler to autoclave the building materials inside for steam curing. After the autoclave curing is complete, to reduce energy waste, the steam from the autoclave is not usually released directly into the atmosphere. Instead, the steam from the autoclave (or discharge autoclave) is poured into a new autoclave (or receiving autoclave) that has been evacuated. As steam is poured out of the discharge autoclave, the pressure in the discharge autoclave gradually decreases, while the pressure in the receiving autoclave gradually increases. When the pressure in the discharge autoclave drops to the same level as that in the receiving autoclave, steam can no longer be poured out, and the remaining steam in the discharge autoclave is directly released into the atmosphere.

[0004] Then, to improve production efficiency, existing technologies typically involve not just two autoclaves, but six, eight, or even more. To transfer steam from one autoclave to another, certain conditions must be met. For example, the autoclave to be discharged cannot be under maintenance, and the autoclave to be filled cannot be under vacuum. Therefore, both autoclaves may experience waiting periods. For the autoclave to discharge steam, the positive pressure of the steam gradually decreases as the waiting time increases; for the autoclave to fill steam, the negative pressure gradually decreases. In other words, the longer the waiting time, the less usable steam is discharged, and the lower the utilization rate of the discharged steam, thus still resulting in energy waste. Summary of the Invention

[0005] This invention provides a method for steam removal from an autoclave, a control device, an electronic device, and a storage medium to solve the technical problem of low utilization rate of steam in the autoclave in the prior art and reduce energy waste.

[0006] This invention provides a method for transferring steam from an autoclave, comprising: sorting the data of autoclaves to which steam is to be transferred in ascending order to form a steam transfer request stack; sorting the data of autoclaves to which steam is to be transferred in descending order to form a steam transfer request stack; transferring a first predetermined amount of steam from the first autoclave in the steam transfer request stack to the first autoclave in the steam transfer request stack; wherein the data represents pressure.

[0007] In an embodiment of the present invention, after pouring a first predetermined amount of steam from the first autoclave in the steam discharge request stack into the first autoclave in the steam input request stack, the autoclave steam discharge method further includes: pouring a second predetermined amount of steam from the first autoclave in the steam discharge request stack into the second autoclave in the steam input request stack.

[0008] In an embodiment of the present invention, after pouring a second predetermined amount of steam from the first autoclave in the steam discharge request stack into the second autoclave in the steam input request stack, the autoclave steam discharge method further includes: pouring a third predetermined amount of steam from the second autoclave in the steam discharge request stack into the second autoclave in the steam input request stack.

[0009] In an embodiment of the present invention, the process of transferring a second predetermined amount of steam from the first autoclave in the steam discharge request stack to the second autoclave in the steam input request stack includes: opening the steam discharge valve corresponding to the first autoclave in the steam discharge request stack; and controlling the opening degree of the steam discharge valve corresponding to the second autoclave in the steam input request stack according to a predetermined pressure rise curve using a fuzzy PID controller, so as to transfer the second predetermined amount of steam from the first autoclave in the steam discharge request stack to the second autoclave in the steam input request stack.

[0010] In an embodiment of the present invention, the first predetermined amount is less than the second predetermined amount.

[0011] In an embodiment of the present invention, when a first predetermined amount of steam from the first autoclave in the steam discharge request stack is poured into the first autoclave in the steam input request stack, the data in the first autoclave in the steam discharge request stack is greater than the data in the first autoclave in the steam input request stack.

[0012] In an embodiment of the present invention, when a first predetermined amount of steam is poured into the first autoclave in the steam discharge request stack and into the first autoclave in the steam input request stack, the pressure difference between the first autoclave in the steam discharge request stack and the first autoclave in the steam input request stack is 0.2 MPa-0.25 MPa.

[0013] The present invention also provides a control device, comprising: a first sorting unit for sorting data of autoclaves to be discharged steam in ascending order to form a discharge steam request stack; a second sorting unit for sorting data of autoclaves to be poured into steam in descending order to form a pouring steam request stack; and a steam pouring unit for pouring a first predetermined amount of steam from the first autoclave in the discharge steam request stack into the first autoclave in the pouring steam request stack; wherein the data represents pressure.

[0014] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps of the above-described autoclave steam reversal method.

[0015] The present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the above-described autoclave steam reversal method.

[0016] The autoclave steam transfer method, control device, electronic equipment, and storage medium provided by this invention can first sort the data of each autoclave to know the waiting time of each autoclave. For autoclaves with steam to be transferred out, the higher the pressure, the shorter the corresponding waiting time, and the lower the pressure, the longer the corresponding waiting time. For autoclaves with steam to be transferred in, the higher the pressure, the longer the corresponding waiting time, and the lower the pressure, the shorter the corresponding waiting time. Based on this, autoclaves with longer waiting times for transferring out steam and autoclaves with longer waiting times for transferring in steam can be transferred first. That is, the first predetermined amount of steam from the first autoclave in the steam transfer request stack is transferred into the first autoclave in the steam transfer request stack. The data represents the pressure, which can reduce the waiting time of autoclaves with steam to be transferred out and the waiting time of autoclaves with steam to be transferred in, reduce energy loss and waste, improve steam utilization, enable autoclaves to operate regularly, and solve the technical problem of low steam utilization in the transfer autoclaves in the prior art.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0025] Figures 1 to 6 This invention illustrates the autoclave steam transfer method, control device, electronic equipment, and storage medium provided by embodiments of the present invention. Figure 1 As can be seen from the embodiments of the present invention, the autoclave steam transfer method includes:

[0026] S110. Sort the data of the autoclaves to be discharged steam in ascending order to form a discharge steam request stack.

[0027] The details are shown in Table 1 below:

[0028] Table 1: Steam Removal Request Stack Cauldron No. 2 Cauldron No. 4 Cauldron No. 3 Cauldron No. 1

[0029] In this embodiment, the data can be pressure, that is, the pressure in the autoclave from which steam is to be discharged. By sorting the pressures of the autoclaves from which steam is to be discharged, the waiting time of the autoclaves from which steam is to be discharged can be determined. For example, the lower the pressure of the autoclave from which steam is to be discharged, the longer the waiting time of the corresponding autoclave from which steam is to be discharged.

[0030] S120. Sort the data of the autoclave to be filled with steam in descending order to form a steam filling request stack.

[0031] The details are shown in Table 2 below:

[0032] Table 2: Gas Injection Request Stack Cauldron No. 6 Cauldron No. 8 Cauldron No. 7 Cauldron No. 5

[0033] In this embodiment, the data can be pressure, that is, the pressure in the autoclave to which steam is to be poured. By sorting the pressures of the autoclaves to which steam is to be poured, the waiting time of the autoclaves to which steam is to be poured can be determined. For example, the higher the pressure of the autoclave to which steam is to be poured, the longer the waiting time of the autoclave to which steam is to be poured.

[0034] S130, pour a first predetermined amount of steam from the first autoclave in the steam discharge request stack into the first autoclave in the steam input request stack; wherein, the data represents the pressure.

[0035] That is, a first predetermined amount of steam from the autoclave with the lowest pressure to be discharged is poured into the autoclave with the highest pressure to be poured in. For example, a pressure sensor can be installed in the autoclave to obtain data from the autoclave.

[0036] The autoclave steam transfer method provided by this invention can first sort the data of each autoclave to know the waiting time of each autoclave. For autoclaves with steam to be transferred out, the higher the pressure, the shorter the corresponding waiting time, and the lower the pressure, the longer the corresponding waiting time. For autoclaves with steam to be transferred in, the higher the pressure, the longer the corresponding waiting time, and the lower the pressure, the shorter the corresponding waiting time. Based on this, autoclaves with longer waiting times for transferring out steam and autoclaves with longer waiting times for transferring in steam can be transferred first. That is, the first predetermined amount of steam from the first autoclave in the steam transfer request stack is transferred into the first autoclave in the steam transfer request stack. The data represents the pressure, which can reduce the waiting time of autoclaves with steam to be transferred out and the waiting time of autoclaves with steam to be transferred in, reduce energy loss and waste, improve steam utilization, enable autoclaves to operate regularly, and solve the technical problem of low steam utilization in the transfer autoclaves in the prior art. Furthermore, since the first predetermined amount of steam from the first autoclave in the steam discharge request stack is poured into the first autoclave in the steam inlet request stack, during the steam discharge process, steam is discharged from one autoclave and steam is introduced into another autoclave. By carrying out the steam discharge in an orderly manner according to this rule, the phenomenon of "steam crosstalk" can be prevented from occurring when multiple autoclaves waiting to discharge steam discharge simultaneously discharge steam.

[0037] In some implementations, the data may characterize temperature. In some implementations, a timer may be used to calculate the waiting time.

[0038] like Figure 2 As shown, specifically, pouring a first predetermined amount of steam from the first autoclave in the steam discharge request stack into the first autoclave in the steam input request stack includes:

[0039] S131. Open the steam discharge valve corresponding to the first autoclave in the steam discharge request stack;

[0040] S132. According to the predetermined pressure rise curve, the opening degree of the steam transfer valve corresponding to the first autoclave in the steam transfer request stack is controlled by the fuzzy PID controller so as to transfer the steam from the first autoclave in the steam transfer request stack to the first autoclave in the steam transfer request stack.

[0041] In practice, the parameters can be dynamically adjusted according to the situation through the above settings, so that it can stably follow the preset pressure curve throughout the entire pressurization process to meet people's needs.

[0042] like Figure 3 As shown, further, after pouring a first predetermined amount of steam from the first autoclave in the steam discharge request stack into the first autoclave in the steam input request stack, the autoclave steam discharge method further includes:

[0043] S140. Pour the second predetermined amount of steam from the first autoclave in the steam discharge request stack into the second autoclave in the steam input request stack. That is, after pouring the first predetermined amount of steam from the autoclave with the lowest pressure steam to be discharged into the autoclave with the highest pressure steam to be input, the second predetermined amount of steam from the autoclave with the lowest pressure steam to be discharged can be poured into the autoclave with the second highest pressure steam to be input. In other words, the steam from the autoclave with the lowest pressure steam to be discharged can be poured into two autoclaves, namely the autoclave with the highest pressure steam to be input and the autoclave with the second highest pressure steam to be input.

[0044] In practical implementation, the steam in the first autoclave in the steam discharge request stack can be fully utilized to reduce the amount of steam emitted into the atmosphere. Compared with the single steam discharge of the prior art, the autoclave of the present invention can perform two steam discharges. For example, usually, before the steam enters the autoclave to be discharged, a vacuum operation needs to be performed on the autoclave to be discharged, so that a negative pressure is formed inside the autoclave to be discharged. For example, the pressure of autoclave No. 2 is 1.2 MPa and the pressure of autoclave No. 6 is -0.5 MPa. When autoclave No. 2 is discharged, the steam discharge can be discharged. When steam from reactor #2 is poured into reactor #6, due to the pressure difference between reactors #2 and #6, steam from reactor #2 will enter reactor #6 under pressure. When the pressure difference is approximately zero, the steam transfer stops. For example, when the pressure in both reactors #2 and #6 is approximately 0.6 MPa, the steam transfer stops. In the prior art, after completing this steam transfer, the steam in reactor #2 is discharged. That is, the prior art only performs one steam transfer, while the present invention can perform two transfers. For example, after steam from reactor #2 is poured into reactor #6, steam from reactor #2 will also be poured into reactor #8.

[0045] Understandably, in the multi-reactor fully automatic steam curing process, the steam from the autoclave that is about to discharge steam after the constant pressure process is completed (e.g., the autoclave at the first position in the discharge steam request stack) is poured into the autoclave that is about to receive steam (e.g., the autoclave at the first position in the input steam request stack) to perform the first-stage steam transfer. When the pressure between the two autoclaves is balanced, the autoclave at the first position in the input steam request stack switches to the steam inlet mode, that is, the steam inlet valve can be opened to allow fresh steam from the boiler to enter the autoclave at the first position in the input steam request stack. The residual steam in the first autoclave in the steam discharge request stack is further discharged into the next autoclave awaiting steam discharge (e.g., the second autoclave in the steam discharge request stack) for a second-stage steam discharge. When the pressure between the two autoclaves is basically balanced, the autoclave discharging steam in the second stage (e.g., autoclave No. 2) switches to exhaust mode to discharge the residual steam to the atmosphere. The autoclave receiving steam in the second stage (the second autoclave in the steam discharge request stack) can switch to intake mode, allowing fresh steam from the boiler to enter, or allowing steam from the second autoclave in the steam discharge request stack to be discharged into the autoclave receiving steam in the second stage. Thus, each autoclave can automatically manage the residual steam during production according to the production schedule, reducing energy consumption while meeting the requirements of the steam curing production process.

[0046] like Figure 4 As shown, in one embodiment of the present invention, pouring a second predetermined amount of steam from the first autoclave in the steam discharge request stack into the second autoclave in the steam input request stack includes:

[0047] S141. Open the steam discharge valve corresponding to the first autoclave in the steam discharge request stack;

[0048] S142. According to the predetermined pressure rise curve, the opening degree of the steam transfer valve corresponding to the second autoclave in the steam transfer request stack is controlled by the fuzzy PID controller so as to transfer the second predetermined amount of steam from the first autoclave in the steam transfer request stack into the second autoclave in the steam transfer request stack.

[0049] In practice, the parameters can be dynamically adjusted according to the situation through the above settings, so that the pressure can stably follow the preset pressure curve throughout the entire pressurization process to meet people's needs.

[0050] It is understandable that traditional PID controllers use fixed parameters, while the fuzzy PID controller of this invention dynamically adjusts the parameters. When setting the pressure rise curve (preset pressure curve), due to process requirements, steam needs to be introduced very slowly in the initial stage of pressure rise to ensure gradual pressure increase and heating of the billet inside the reactor. However, in the later stage of pressure rise, the pressure inside the reactor needs to quickly reach a constant value. Therefore, the rate of change of the pressure rise curve is very different before and after. Traditional PID controllers with fixed parameters will either adjust too slowly in the later stage to follow the earlier stage, or cause oscillations and overshoot in the earlier stage. In other words, the fuzzy PID controller can dynamically adjust its parameters according to the situation, ensuring stable tracking of the preset pressure curve throughout the entire pressure rise process.

[0051] like Figure 3 As shown, further, after pouring a second predetermined amount of steam from the first autoclave (e.g., autoclave No. 2) in the steam discharge request stack into the second autoclave (e.g., autoclave No. 8) in the steam input request stack, the autoclave steam discharge method may also include:

[0052] S150. A third predetermined amount of steam from the second-ranked autoclave (e.g., autoclave No. 4) in the steam discharge request stack is poured into the second-ranked autoclave (e.g., autoclave No. 8) in the steam input request stack. In specific implementation, through the above settings, steam can be added twice to the second-ranked autoclave (e.g., autoclave No. 8) in the steam input request stack. Compared with the prior art, there is no need for a steam compressor to pressurize the steam in the discharge autoclave, and the structure is simple. This further solves the technical problem of low steam utilization rate in the discharge autoclave in the prior art and reduces energy waste.

[0053] Specifically, a multi-level queuing order stack for pouring out and pouring in can be generated based on the pouring out request stack and the pouring in request stack mentioned above, as shown in Table 3 below:

[0054]

[0055] The data of the autoclaves to be discharged steam are sorted in ascending order: autoclaves 2, 4, 3, and 1. The data of the autoclaves to be poured into steam are sorted in descending order: autoclaves 6, 8, 7, and 5. That is, the first predetermined amount of steam from the first autoclave in the discharge request stack is poured into the first autoclave in the pouring request stack, which is equivalent to pouring the first predetermined amount of steam from autoclave 2 into autoclave 6. This is the first order. The second predetermined amount of steam from the first autoclave in the discharge request stack is poured into the second autoclave in the pouring request stack, which is equivalent to pouring the second predetermined amount of steam from autoclave 2 into autoclave 8. That is, each steam valve can automatically and orderly perform steam transfer according to the order of the multi-stage queuing sequence stack in Table 3, and the controller can control the steam transfer to achieve fully automatic steam transfer.

[0056] It is understandable that in some implementations, it may also be a third-order or fourth-order, etc.

[0057] In some implementations, it can be determined whether the priority autoclave has met the conditions for pouring out or pouring in (for example, due to autoclave cycle and production turnover, it is not possible to ensure that when one autoclave meets the conditions for pouring out steam, the other autoclave also meets the conditions for inlet steam, as ideally).

[0058] When one autoclave meets the conditions for steam discharge, if the autoclave receiving residual steam (the autoclave receiving steam) does not meet the conditions for steam inflow, the autoclave discharging steam enters the steam discharge waiting stage. If multiple autoclaves have already passed the constant pressure stage and entered the steam discharge stage at this time, they need to wait, that is, the steam discharge queue needs to be formed.

[0059] When one autoclave meets the conditions for steam pouring, if the autoclave for steam discharge does not yet meet the conditions for steam discharge, the autoclave for steam pouring enters the steam pouring waiting stage. If multiple autoclaves have entered the steam pouring stage after the vacuuming stage, they need to wait, that is, the steam pouring queue is formed.

[0060] When both the steam-exporting autoclave and the steam-in autoclave meet the conditions, the two autoclaves enter the steam-reversing stage. The steam-reversing valve corresponding to the steam-exporting autoclave is fully open, and the steam-reversing valve corresponding to the steam-injecting autoclave is adjusted according to the set pressure rise curve using PID (Proportion Integration Differentiation) to control the steam-reversing speed by following the pressure curve.

[0061] When the pressure of the autoclave that discharges steam (e.g., autoclave No. 2) and the autoclave that receives steam (e.g., autoclave No. 6) reaches pressure balance, the autoclave that discharges steam (e.g., autoclave No. 2) closes its steam discharge valve and enters the second-stage discharge waiting stage. The autoclave that receives steam (e.g., autoclave No. 6) switches from the steam discharge valve to the steam inlet valve and performs PID regulation of the steam inlet according to the set pressure rise curve.

[0062] When the autoclave waiting for steam discharge (e.g., autoclave No. 2) is matched with an autoclave that meets the steam discharge conditions, the second stage of steam discharge begins. The remaining steam after the first stage discharge is discharged into a new autoclave that has been evacuated and has not yet received steam (e.g., autoclave No. 8).

[0063] When the pressure balance is reached between the autoclave that discharges steam (e.g., autoclave No. 2) and the autoclave that receives steam (e.g., autoclave No. 8), the autoclave that discharges steam (e.g., autoclave No. 2) stops discharging steam, and the autoclave that receives steam (e.g., autoclave No. 8) waits for the next autoclave (e.g., autoclave No. 4) that meets the discharge conditions to continue discharging steam into that autoclave (e.g., autoclave No. 8).

[0064] In this embodiment, the first predetermined amount is less than the second predetermined amount. This structural arrangement ensures the normal operation of subsequent processes and improves steam transfer efficiency and energy utilization.

[0065] In practice, before steam enters the autoclave to be filled with steam, a vacuum operation needs to be performed on the autoclave to create a negative pressure inside, for example, the pressure of autoclave No. 6 is -0.5 MPa. When steam from autoclave No. 2 is poured into autoclave No. 6, for example, the pressure of autoclave No. 2 is 1.2 MPa, due to the pressure difference between autoclave No. 2 and autoclave No. 6, the steam from autoclave No. 2 (the first predetermined amount) will enter autoclave No. 6 under the pressure. When the pressure difference is approximately zero, the steam transfer automatically stops. For example, when the pressure of both autoclave No. 2 and autoclave No. 6 is approximately 0.6 MPa, the steam transfer stops. Then, when steam from autoclave No. 2 is poured into autoclave No. 8, before the steam from autoclave No. 2 enters autoclave No. 8, due to the pressure difference between autoclave No. 2 and autoclave No. 6, the steam transfer will be automatically stopped. The reactors are also evacuated. For example, the pressure of reactor No. 8 is -0.5 MPa. Due to the pressure difference between reactor No. 2 (0.6 MPa) and reactor No. 8 (-0.5 MPa), steam from reactor No. 2 (second predetermined amount) will enter reactor No. 8 under the pressure. When the pressure difference is basically zero, the steam transfer stops. For example, when the pressure of both reactor No. 2 and reactor No. 8 is basically 0.3 MPa, the steam transfer stops. Then, when steam from reactor No. 4 (third predetermined amount) is transferred into reactor No. 8, for example, the pressure of reactor No. 4 is 1.2 MPa and the pressure of reactor No. 8 is 0.3 MPa, due to the large pressure difference, more steam can be transferred into reactor No. 8 to ensure the normal operation of subsequent processes and improve the steam transfer efficiency and energy utilization rate.

[0066] In one embodiment of the present invention, when a first predetermined amount of steam from the first autoclave in the steam discharge request stack is poured into the first autoclave in the steam input request stack, the data in the first autoclave in the steam discharge request stack is greater than the data in the first autoclave in the steam input request stack.

[0067] In practice, when the first predetermined amount of steam from the first autoclave in the steam discharge request stack is being discharged into the first autoclave in the steam input request stack, if the pressure difference between the two autoclaves is 0, the steam discharge speed will be slow, or there may even be a situation where steam discharge is waiting, which will affect the steam discharge efficiency and thus the overall turnover efficiency.

[0068] Furthermore, when a predetermined amount of steam is poured into the first autoclave in the steam discharge request stack and into the first autoclave in the steam input request stack, the pressure difference between the first autoclave in the steam discharge request stack and the first autoclave in the steam input request stack is 0.2 MPa - 0.25 MPa.

[0069] In practice, controlling the pressure difference between 0.2MPa and 0.25MPa can improve the steam transfer efficiency, thereby increasing the turnover efficiency. In other words, the next step can be carried out after the steam transfer is basically completed, thus solving the technical problem of slow steam transfer speed.

[0070] like Figure 3 As shown, in one embodiment of the present invention, after pouring a first predetermined amount of steam from the first autoclave in the steam discharge request stack into the first autoclave in the steam input request stack, the autoclave steam discharge method further includes:

[0071] S160. Close the steam discharge valve corresponding to the autoclave, which is the first item in the steam discharge request stack;

[0072] S170. According to the predetermined pressure rise curve, the opening degree of the steam inlet valve corresponding to the first autoclave in the steam pouring request stack is controlled by the fuzzy PID controller so as to put the boiler steam into the autoclave with the largest data to be poured steam.

[0073] In practice, the parameters can be dynamically adjusted according to the situation through the above settings, so that it can stably follow the preset pressure curve throughout the entire pressurization process to meet people's needs.

[0074] like Figure 5As shown, this embodiment of the invention also provides a control device, including a first sorting unit 210, a second sorting unit 220, and a steam pouring unit 230. The first sorting unit 210 is used to sort the data of the autoclaves to which steam is to be poured out in ascending order to form a steam pouring request stack. The second sorting unit 220 is used to sort the data of the autoclaves to which steam is to be poured in in descending order to form a steam pouring request stack. The steam pouring unit 230 is used to pour a first predetermined amount of steam from the first autoclave in the steam pouring request stack into the first autoclave in the steam pouring request stack. The data represents pressure.

[0075] The control device provided in this embodiment of the invention can first sort the data of each autoclave to know the waiting time of each autoclave. For autoclaves waiting to discharge steam, the higher the pressure, the shorter the corresponding waiting time, and the lower the pressure, the longer the corresponding waiting time. For autoclaves waiting to receive steam, the higher the pressure, the longer the corresponding waiting time, and the lower the pressure, the shorter the corresponding waiting time. Based on this, autoclaves with longer waiting times for discharge and receiving steam can be processed first. That is, the first predetermined amount of steam from the autoclave at the top of the discharge request stack is poured into the autoclave at the top of the receiving request stack. The data represents the pressure, which can reduce the waiting time of autoclaves waiting to discharge steam and autoclaves waiting to receive steam, reduce energy loss and waste, improve steam utilization, enable autoclaves to operate regularly, and solve the technical problem of low steam utilization in discharge autoclaves in the prior art.

[0076] like Figure 6 As shown, this embodiment of the invention also provides an electronic device, which may include: a processor 310, a communication interface 320, a memory 330, and a communication bus 340, wherein the processor 310, the communication interface 320, and the memory 330 communicate with each other through the communication bus 340. The processor 310 can call logical instructions in the memory 330 to execute a steam transfer method for autoclaves. The steam transfer method for autoclaves includes: sorting the data of autoclaves to which steam is to be transferred in ascending order to form a steam transfer request stack; sorting the data of autoclaves to which steam is to be transferred in descending order to form a steam transfer request stack; and transferring a first predetermined amount of steam from the first autoclave in the steam transfer request stack to the first autoclave in the steam transfer request stack; wherein the data represents pressure.

[0077] The electronic device provided in this invention can first sort the data of each autoclave to know the waiting time of each autoclave. For autoclaves waiting to discharge steam, the higher the pressure, the shorter the corresponding waiting time, and the lower the pressure, the longer the corresponding waiting time. For autoclaves waiting to receive steam, the higher the pressure, the longer the corresponding waiting time, and the lower the pressure, the shorter the corresponding waiting time. Based on this, autoclaves with longer waiting times for discharge and autoclaves with longer waiting times for receiving steam can be discharged first. That is, the first predetermined amount of steam from the autoclave at the top of the discharge request stack is poured into the autoclave at the top of the receiving request stack. The data represents the pressure, which can reduce the waiting time of autoclaves waiting to discharge steam and autoclaves waiting to receive steam, reduce energy loss and waste, improve steam utilization, enable autoclaves to operate regularly, and solve the technical problem of low steam utilization in discharge autoclaves in the prior art.

[0078] This invention also provides a non-transitory computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the steps of the above-described autoclave steam reversal method.

[0079] The non-transitory computer-readable storage medium provided in this invention can first sort the data of each autoclave to know the waiting time of each autoclave. For autoclaves waiting to discharge steam, the higher the pressure, the shorter the corresponding waiting time, and the lower the pressure, the longer the corresponding waiting time. For autoclaves waiting to receive steam, the higher the pressure, the longer the corresponding waiting time, and the lower the pressure, the shorter the corresponding waiting time. Based on this, autoclaves with longer waiting times for discharging steam and autoclaves with longer waiting times for receiving steam can complete the steam transfer first. That is, the first predetermined amount of steam from the first autoclave in the steam discharge request stack is transferred to the first autoclave in the steam inlet request stack. The data represents the pressure, which can reduce the waiting time of autoclaves waiting to discharge steam and autoclaves waiting to receive steam, reduce energy loss and waste, improve steam utilization, enable autoclaves to operate regularly, and solve the technical problem of low steam utilization in discharge autoclaves in the prior art.
