Description

Technical Field

[0001] This invention relates to the field of electronic digital data processing technology, and in particular to a design method, apparatus, computer equipment, and storage medium for intelligent chemical equipment. Background Technology

[0002] Chemical process equipment is a key component of normal operation and production in the petrochemical industry. Under the premise of meeting strength and service life requirements, reducing the time required for equipment design and manufacturing processes and delivering the equipment as early as possible are the key points to ensure the timely completion of the project.

[0003] Chemical processing equipment often comprises multiple reaction or storage components, and their designs are frequently interconnected. For example, the design of a drying tower and a regeneration heater in a chemical equipment system typically requires the design parameters of the regeneration heater to be based on parameters of the drying tower. Current chemical equipment designs often involve manual calculations, determining equipment size, packing material, regeneration gas heat load, etc., based on specific equipment requirements, and selecting appropriate corrosion protection and insulation methods according to the local working environment. After calculation, a calculation sheet, drawings, and design flow chart are produced. This entire process requires manual calculation and organization, and errors in the calculation process or parameter selection can affect the use of the entire equipment, causing unnecessary property damage. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention proposes an intelligent chemical equipment design method, device, computer equipment, and storage medium.

[0005] The present invention proposes a design method for intelligent chemical equipment, comprising the following steps:

[0006] S1. Obtain the type of chemical equipment to be designed, as well as the design parameters of the chemical equipment to be designed. Select a three-dimensional model template according to the design parameters of the chemical equipment to be designed. The three-dimensional model template includes the original model and the design model. The original model includes the shape of the equipment, the inlet and the outlet. The design model includes at least one of the following: the shape of the equipment, the inlet and the outlet, accessories, and a specific range of design parameters.

[0007] S2. Calculate the equipment parameters based on the design parameters of the chemical equipment to be designed. The equipment parameters include one or more of the following: equipment dimensions, manufacturing process, main body material of the equipment, and internal packing.

[0008] S3. Adjust the 3D model template according to the equipment parameters, and add or adjust attachments to the adjusted 3D model to form a design model;

[0009] It should be noted that designers can manually input and modify the 3D model template based on equipment parameters, or they can modify the 3D model template through a computer's processor.

[0010] If, during the adjustment of the 3D model, a certain parameter causes a change in size that results in the addition of a specific feature to the 3D model template, then that size is the specific parameter, and the range of specific design parameters corresponding to that specific parameter is obtained.

[0011] S4. Verify the design model. If the design model passes the verification, proceed to the next step. If the design model fails the verification, return to step S3. Verify the design model according to the design specifications.

[0012] S5 outputs equipment calculation sheets, two-dimensional drawings, and design models, while storing the design model and its design parameters, equipment parameters, and specific design parameter ranges. This design model can be used as one of the three-dimensional model templates selected for the next chemical equipment design.

[0013] Preferably, step S1 further includes determining whether the design parameters of the chemical equipment to be designed have specific parameters:

[0014] If the design parameters of the chemical equipment to be designed have specific parameters, determine whether the specific parameters of the chemical equipment to be designed fall within the specific design parameter range of the design model. If the specific parameters of the chemical equipment to be designed fall within the specific design parameter range of the design model, the selected 3D model template is the design model with that specific design parameter range; if the specific parameters do not fall within the specific design parameter range of the design model, the selected 3D model template is the original model.

[0015] If the design parameters of the chemical equipment to be designed do not have specific parameters, the difference between the design parameters of the chemical equipment to be designed and the design parameters of the design model is compared. If the difference is within the set threshold, the 3D model template is the design model; otherwise, the 3D model is the original model.

[0016] The main reason for this step is that in the field of chemical equipment, a chemical system usually consists of multiple chemical equipment. Due to different design parameters, the number of equipment in the entire chemical system may be different. Therefore, the positions of the feed inlets, discharge outlets or accessories on the equipment may be different. By using the 3D model template as the original model when the design parameters exceed the threshold, we can avoid large adjustments to the 3D model in the later stage (step S3). If the design parameters do not exceed the threshold, the 3D model is the design model.

[0017] For example, in a natural gas dehydration system, the temperature of the natural gas entering the absorption tower should be between 15℃ and 48℃. If it is greater than 48℃, a cooling facility should be installed before the inlet separator. If it is less than 15℃, a heating facility should be installed after the separator. The cooling facility and the heating facility are specific characteristics of the separator, and the temperature of the natural gas entering the absorption tower is a specific parameter. 15℃-48℃, less than 15℃, and greater than 48℃ are all specific design parameter ranges.

[0018] The 3D model templates in this method are constantly updated, and the specific design parameter range corresponding to each 3D model template is also updated. For example, if there is only an original model of a separator in the design process, and it is found that the original model has specific parameters during the calculation process, then the design model with the value of the specific parameter within the range can be used as one of the selectable 3D design model templates for the next chemical equipment to be designed.

[0019] Preferably, if the three-dimensional model template selected in step S1 is a design model, then the sum of the differences of all parameters of the design model is minimized.

[0020] Preferably, if the 3D model template selected in step S1 is a design model with a specific range of design parameters, then the selection difference of this design model is minimized.

[0021] Select the difference = a * | Specific parameter - median value of specific design parameter range | + b * | Design parameters of the chemical equipment to be designed - Design parameters of the design model |;

[0022] Where: a+b=1.

[0023] Preferably, a < b. More preferably, since the magnitude of a specific parameter relative to the middle value of the design parameter range affects the parameter of a specific feature to a certain extent, and to a certain extent, a takes 0.3 and b takes 0.7 for this parameter.

[0024] Preferably, if the chemical equipment is connected to a model in the design model, then the design parameters include the equipment parameters of the design model.

[0025] Preferably, step S2 further includes the selection of design parameters and the calculation of equipment parameters according to the equipment parameter calculation formula.

[0026] A design device for intelligent chemical equipment, comprising:

[0027] Input module: Used to input the type of chemical equipment, design parameters, calculation formulas, original model, and adjust the 3D model. The input module is also used to input specific parameters and specific design parameter ranges.

[0029] Extraction module: Used to extract the calculation formulas and design parameters of the storage module;

[0030] Calculation module: Used to calculate equipment parameters based on calculation formulas and design parameters;

[0032] Output module: Used to output one or more of the following: device calculation sheets, two-dimensional drawings, and three-dimensional models.

[0034] A storage medium characterized in that it is used to store a program for implementing the above-described intelligent chemical equipment design method.

[0035] In this invention, the proposed intelligent chemical equipment design method, apparatus, computer equipment, and storage medium select a 3D model template that is closest to the shape, accessories, and size of the chemical equipment to be designed based on its design parameters. This allows for a more intuitive observation of the equipment's appearance and facilitates smaller adjustments to the 3D model after calculating the equipment parameters, ensuring the precision and accuracy of the adjustments. At the same time, a well-designed model can serve as one of the 3D model templates for the next chemical equipment to be designed, further facilitating the design of the next chemical equipment.

[0039] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] like Figure 1-2The intelligent chemical equipment design method shown includes the following steps:

[0041] S1. Obtain the type of chemical equipment to be designed, as well as the design parameters of the chemical equipment to be designed. Select a three-dimensional model template according to the design parameters of the chemical equipment to be designed. The three-dimensional model template includes the original model and the design model. The original model includes the shape of the equipment, the inlet and the outlet. The design model includes at least one of the following: the shape of the equipment, the inlet and the outlet, accessories, and a specific range of design parameters.

[0042] S2. Calculate the equipment parameters based on the design parameters of the chemical equipment to be designed. The equipment parameters include one or more of the following: equipment dimensions, manufacturing process, main body material of the equipment, and internal packing.

[0043] S3. Adjust the 3D model template according to the equipment parameters, and add or adjust attachments to the adjusted 3D model to form a design model;

[0044] It should be noted that designers can manually input and modify the 3D model template based on equipment parameters, or they can modify the 3D model template through a computer's processor.

[0045] If, during the adjustment of the 3D model, a certain parameter causes a change in size that results in the addition of a specific feature to the 3D model template, then that size is the specific parameter, and the range of specific design parameters corresponding to that specific parameter is obtained.

[0046] S4. Verify the design model. If the design model passes the verification, proceed to the next step. If the design model fails the verification, return to step S3. Verify the design model according to the design specifications.

[0047] S5 outputs equipment calculation sheets, two-dimensional drawings, and design models, while storing the design model and its design parameters, equipment parameters, and specific design parameter ranges. This design model can be used as one of the three-dimensional model templates selected for the next chemical equipment design.

[0048] Preferably, step S1 further includes determining whether the design parameters of the chemical equipment to be designed have specific parameters:

[0049] If the design parameters of the chemical equipment to be designed have specific parameters, determine whether the specific parameters of the chemical equipment to be designed fall within the specific design parameter range of the design model. If the specific parameters of the chemical equipment to be designed fall within the specific design parameter range of the design model, the selected 3D model template is the design model with that specific design parameter range; if the specific parameters do not fall within the specific design parameter range of the design model, the selected 3D model template is the original model.

[0050] If the design parameters of the chemical equipment to be designed do not have specific parameters, the difference between the design parameters of the chemical equipment to be designed and the design parameters of the design model is compared. If the difference is within the set threshold, the 3D model template is the design model; otherwise, the 3D model is the original model.

[0051] The main reason for this step is that in the field of chemical equipment, a chemical system usually consists of multiple chemical equipment. Due to different design parameters, the number of equipment in the entire chemical system may be different. Therefore, the positions of the feed inlets, discharge outlets or accessories on the equipment may be different. By using the 3D model template as the original model when the design parameters exceed the threshold, we can avoid large adjustments to the 3D model in the later stage (step S3). If the design parameters do not exceed the threshold, the 3D model is the design model.

[0052] For example, in a natural gas dehydration system, the temperature of the natural gas entering the absorption tower should be between 15℃ and 48℃. If it is greater than 48℃, a cooling facility should be installed before the inlet separator. If it is less than 15℃, a heating facility should be installed after the separator. The cooling facility and the heating facility are specific characteristics of the separator, and the temperature of the natural gas entering the absorption tower is a specific parameter. 15℃-48℃, less than 15℃, and greater than 48℃ are all specific design parameter ranges.

[0053] The 3D model templates in this method are constantly updated, and the specific design parameter range corresponding to each 3D model template is also updated. For example, if there is only an original model of a separator in the design process, and it is found that the original model has specific parameters during the calculation process, then the design model with the value of the specific parameter within the range can be used as one of the selectable 3D design model templates for the next chemical equipment to be designed.

[0054] Preferably, if the three-dimensional model template selected in step S1 is a design model, then the sum of the differences of all parameters of the design model is minimized.

[0055] Preferably, if the 3D model template selected in step S1 is a design model with a specific range of design parameters, then the selection difference of this design model is minimized.

[0056] Select the difference = a * | Specific parameter - median value of specific design parameter range | + b * | Design parameters of the chemical equipment to be designed - Design parameters of the design model |;

[0057] Where: a+b=1.

[0058] Preferably, a < b. More preferably, since the magnitude of a specific parameter relative to the middle value of the design parameter range affects the parameter of a specific feature to a certain extent, and to a certain extent, a takes 0.3 and b takes 0.7 for this parameter.

[0059] Preferably, if the chemical equipment is connected to a model in the design model, then the design parameters include the equipment parameters of the design model.

[0060] Preferably, step S2 further includes the selection of design parameters and the calculation of equipment parameters according to the equipment parameter calculation formula.

[0069] A storage medium characterized in that it is used to store a program for implementing the above-described intelligent chemical equipment design method.

[0070] The above method was used to design an adsorption dehydration process for natural gas.

[0071] Step 1: Designers access the equipment design system, select the required equipment category in the design interface to enter the next level interface, select the equipment type, and then enter the design parameter input interface. The system automatically loads the equipment's reference 3D model, where designers input the equipment design parameters and intended use. Step 2: Based on the data from Step 1, the system calculates the main equipment parameters and intended use, determines the equipment's external parameters, and automatically completes the internal design according to requirements, such as filler type and height. The system then modifies the 3D model based on the calculated parameters and outputs the calculated and modified model to the user interface. Designers add equipment selection options to the completed 3D model, add accessories to the main equipment body, and adjust their positions. The adjusted equipment model and the output data from the equipment calculation process are then submitted to the verification personnel for review.

[0072] Step 3: After receiving the equipment model and calculation process, the verification personnel will verify the equipment. If the equipment verification passes, the equipment design process is completed, and the system will output the equipment calculation sheet, manufacturing documents, equipment drawings, and equipment model. If the equipment verification fails, the designer will reselect the main equipment materials, fillers, and other data in the design interface and repeat the above steps.
