Description

Technical Field

[0001] The present invention belongs to the field of benzene hydrogenation loading and unloading, and relates to safety supervision technology. Specifically, it is a safety multi-level collaborative processing system for the loading and unloading vehicle process in the benzene hydrogenation process. Background Art

[0002] Benzene hydrogenation loading and unloading refers to the key operation links of receiving, storing, transporting and transferring crude benzene raw materials, hydrogen and products such as cyclohexane in the benzene hydrogenation production process. The core is to realize the closed and safe transfer of hazardous chemicals through special equipment, and meet the safety and environmental protection requirements such as explosion prevention and leakage prevention.

[0003] The existing safety multi-level collaborative processing system for the loading and unloading vehicle process in the benzene hydrogenation process can only collect and analyze the risk parameters at the loading and unloading site, and evaluate the safety of the loading and unloading site according to the analysis results. However, it is unable to investigate the influencing factors when the safety risk is abnormal, resulting in low risk handling efficiency.

[0004] In view of the above technical problems, the present application proposes a solution. Summary of the Invention

[0005] The purpose of the present invention is to provide a safety multi-level collaborative processing system for the loading and unloading vehicle process in the benzene hydrogenation process, which is used to solve the problem that the existing technology cannot investigate the influencing factors when the safety risk is abnormal;

[0006] The technical problem to be solved by the present invention is: how to provide a safety multi-level collaborative processing system for the loading and unloading vehicle process in the benzene hydrogenation process that can investigate the influencing factors when the safety risk is abnormal.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] A safety multi-level collaborative processing system for the loading and unloading vehicle process in the benzene hydrogenation process includes a loading and unloading risk monitoring module, a loading and unloading risk assessment module, and a risk investigation module that are connected in sequence. The loading and unloading risk monitoring module, the loading and unloading risk assessment module, and the risk investigation module are all in communication connection with the database;

[0009] The loading and unloading risk monitoring module is used to conduct safety risk monitoring and analysis on the loading and unloading vehicle process of the benzene hydrogenation process: mark the loading and unloading vehicle process of the benzene hydrogenation process as the monitoring process, set a number of monitoring time points with equal time intervals during the monitoring process, and obtain the risk coefficient FX of the loading and unloading site at the monitoring time points; send the risk coefficient FX of the loading and unloading site at the monitoring time points to the loading and unloading risk assessment module;

[0010] The loading and unloading risk assessment module is used to conduct a safety risk assessment and analysis on the loading and unloading process of the benzene hydrogenation process, and generate a risk investigation signal and send it to the risk investigation module when the safety risk at the monitoring time point does not meet the requirements;

[0011] The risk investigation module is used to conduct an investigation and analysis on the safety risk factors at the loading and unloading site.

[0012] Further, the process of obtaining the risk coefficient FX at the monitoring time point includes: obtaining the benzene concentration data BN, ventilation data TF, and static electricity data JD at the monitoring time point and performing numerical calculations to obtain the risk coefficient FX at the monitoring time point. The benzene concentration data BN is the concentration value of benzene vapor in the air at the loading and unloading site, the ventilation data TF is the air flow velocity at the loading and unloading site, and the static electricity data JD is the amount of electric charge during loading and unloading.

[0013] Further, the specific process of the loading and unloading risk assessment module conducting a safety risk assessment and analysis on the loading and unloading process of the benzene hydrogenation process includes: obtaining the risk threshold FXmax through the database, and comparing the risk coefficient FX with the risk threshold FXmax: if the risk coefficient FX is less than the risk threshold FXmax, it is determined that the safety risk at the loading and unloading site of the benzene hydrogenation process meets the requirements at the monitoring time point; if the risk coefficient FX is greater than or equal to the risk threshold FXmax, it is determined that the safety risk at the loading and unloading site of the benzene hydrogenation process does not meet the requirements at the monitoring time point.

[0014] Further, the specific process of the risk investigation module conducting an investigation and analysis on the safety risk factors at the loading and unloading site includes: obtaining the air pressure value of the loading and unloading conveying pipeline and marking it as the pressure monitoring value, determining whether the safety risk factor is pipeline leakage through the pressure monitoring value. If it is not pipeline leakage, obtain the air temperature value at the loading and unloading site and mark it as the temperature monitoring value, and mark the safety risk factor as high-temperature volatilization or poor ventilation through the temperature monitoring value.

[0015] Further, the specific process of determining whether the safety risk factor is pipeline leakage includes: obtaining the pressure monitoring threshold through the database, and comparing the pressure monitoring value with the pressure monitoring threshold: if the pressure monitoring value is less than the pressure monitoring threshold, mark the safety risk factor as pipeline leakage, generate a leakage treatment signal and send the leakage treatment signal to the mobile terminal of the management personnel; if the pressure monitoring value is greater than or equal to the pressure monitoring value, the safety risk factor is not pipeline leakage.

[0016] Further, the specific process of marking safety risk factors as high-temperature volatilization or poor ventilation includes: obtaining the temperature monitoring threshold through the database, and comparing the temperature monitoring value with the temperature monitoring threshold. If the temperature monitoring value is greater than the temperature monitoring threshold, the safety risk factor is marked as high-temperature volatilization, a spray settlement signal is generated and sent to the mobile terminal of the management personnel. If the temperature monitoring value is less than or equal to the temperature monitoring threshold, the safety risk factor is marked as poor ventilation, a ventilation optimization signal is generated and sent to the mobile terminal of the management personnel.

[0017] Further, the working method of the loading and unloading vehicle process safety multi-level collaborative processing system applied to the benzene hydrogenation process includes the following steps:

[0018] Step 1: Conduct safety risk monitoring and analysis on the loading and unloading vehicle process of the benzene hydrogenation process;

[0019] Step 2: Conduct safety risk assessment and analysis on the loading and unloading vehicle process of the benzene hydrogenation process;

[0020] Step 3: Conduct investigation and analysis on the safety risk factors at the loading and unloading vehicle site.

[0021] The present invention has the following beneficial effects:

[0022] 1. Through the loading and unloading risk monitoring module, safety risk monitoring and analysis can be carried out on the loading and unloading vehicle process of the benzene hydrogenation process, multiple risk parameters at the loading and unloading site of the benzene hydrogenation process are collected and comprehensively calculated to obtain a risk coefficient, and the risk degree at the loading and unloading site is fed back through the risk coefficient;

Through the loading and unloading risk assessment module, safety risk assessment and analysis can be carried out on the loading and unloading vehicle process of the benzene hydrogenation process, and it is determined whether the safety risk at the loading and unloading vehicle site meets the requirements at the monitoring time point through the risk coefficient. Furthermore, when the safety risk does not meet the requirements, an early warning is given in a timely manner, and at the same time, a risk investigation signal is generated to improve the timeliness of risk handling;

[0024] 3. Through the risk investigation module, investigation and analysis can be carried out on the safety risk factors at the loading and unloading vehicle site, the safety risk factors are investigated one by one in combination with the air pressure value and air temperature value of the conveying pipeline at the loading and unloading vehicle site, and the safety risk factors are marked according to the investigation results to improve the risk handling efficiency.

[0028] Next, the technical solutions of the present invention will be described clearly and completely in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: As Figure 1 shown, a multi-level collaborative processing system for the safety of the loading and unloading process of the benzene hydrogenation process includes a loading and unloading risk monitoring module, a loading and unloading risk assessment module, and a risk investigation module that are connected in sequence. The loading and unloading risk monitoring module, the loading and unloading risk assessment module, and the risk investigation module are all communicatively connected to the database.

[0030] The loading and unloading risk monitoring module is used to conduct safety risk monitoring and analysis on the loading and unloading process of the benzene hydrogenation process: mark the loading and unloading process of the benzene hydrogenation process as the monitoring process, set a number of monitoring time points with equal time intervals during the monitoring process, obtain the benzene concentration data BN, ventilation data TF, and static electricity data JD at the loading and unloading site at the monitoring time point. The benzene concentration data BN is the concentration value of benzene vapor in the air at the loading and unloading site, the ventilation data TF is the air flow velocity at the loading and unloading site, and the static electricity data JD is the charge amount of the loading and unloading vehicle. Obtain the risk coefficient FX at the monitoring time point through the formula FX = k1×BN - k2×TF + k3×JD, where k1, k2, and k3 are the preset weight coefficients of the benzene concentration data BN, ventilation data TF, and static electricity data JD respectively, and the values of k1, k2, and k3 are 3.25, 2.51, and 3.37 respectively; send the risk coefficient FX at the loading and unloading site at the monitoring time point to the loading and unloading risk assessment module; conduct safety risk monitoring and analysis on the loading and unloading process of the benzene hydrogenation process, collect and comprehensively calculate multiple risk parameters at the loading and unloading site of the benzene hydrogenation process to obtain the risk coefficient, and feedback the risk degree of the loading and unloading site through the risk coefficient.

[0031] The loading and unloading risk assessment module is used to conduct a safety risk assessment and analysis on the loading and unloading process of the benzene hydrogenation process: obtain the risk threshold FXmax through the database, and compare the risk coefficient FX with the risk threshold FXmax. If the risk coefficient FX is less than the risk threshold FXmax, it is determined that the safety risk at the loading and unloading site of the benzene hydrogenation process meets the requirements at the monitoring time point. If the risk coefficient FX is greater than or equal to the risk threshold FXmax, it is determined that the safety risk at the loading and unloading site of the benzene hydrogenation process does not meet the requirements at the monitoring time point, generate a risk investigation signal and send the risk investigation signal to the risk investigation module. Conduct a safety risk assessment and analysis on the loading and unloading process of the benzene hydrogenation process, determine whether the safety risk at the loading and unloading site meets the requirements at the monitoring time point through the risk coefficient, and then give an early warning in time when the safety risk does not meet the requirements. At the same time, generate a risk investigation signal to improve the timeliness of risk handling.

[0032] The risk investigation module is used to conduct a screening and analysis on the safety risk factors at the loading and unloading site: obtain the air pressure value of the loading and unloading conveying pipeline and mark it as the pressure monitoring value, obtain the pressure monitoring threshold through the database, and compare the pressure monitoring value with the pressure monitoring threshold. If the pressure monitoring value is less than the pressure monitoring threshold, mark the safety risk factor as pipeline leakage, generate a leakage treatment signal and send the leakage treatment signal to the mobile terminal of the management personnel. If the pressure monitoring value is greater than or equal to the pressure monitoring value, obtain the air temperature value at the loading and unloading site and mark it as the temperature monitoring value, obtain the temperature monitoring threshold through the database, and compare the temperature monitoring value with the temperature monitoring threshold. If the temperature monitoring value is greater than the temperature monitoring threshold, mark the safety risk factor as high-temperature volatilization, generate a spray settlement signal and send the spray settlement signal to the mobile terminal of the management personnel. If the temperature monitoring value is less than or equal to the temperature monitoring threshold, mark the safety risk factor as poor ventilation, generate a ventilation optimization signal and send the ventilation optimization signal to the mobile terminal of the management personnel. Conduct a screening and analysis on the safety risk factors at the loading and unloading site, conduct a one-by-one screening of the safety risk factors in combination with the air pressure value and air temperature value of the conveying pipeline at the loading and unloading site, and mark the safety risk factors based on the screening results to improve the efficiency of risk handling.

[0033] Example 2: As Figure 2 shown, a multi-level collaborative processing method for the safety of the loading and unloading process of the benzene hydrogenation process includes the following steps:

[0034] Step 1: Conduct a safety risk monitoring and analysis on the loading and unloading process of the benzene hydrogenation process: Mark the loading and unloading process of the benzene hydrogenation process as the monitoring process, set several monitoring time points with equal time intervals during the monitoring process, and obtain the risk coefficient FX of the loading and unloading site at the monitoring time point.

[0035] Step 2: Conduct a safety risk assessment and analysis on the loading and unloading process of the benzene hydrogenation process: Compare the risk coefficient FX with the risk threshold FXmax, and determine whether the safety risk at the loading and unloading site meets the requirements at the monitoring time point based on the comparison result.

[0036] Step 3: Conduct a screening and analysis of the safety risk factors at the loading and unloading site: Obtain the pressure monitoring value and temperature monitoring value at the loading and unloading site, and mark the safety risk factors based on the pressure monitoring value and temperature monitoring value.

[0037] The multi-level collaborative safety processing system for the loading and unloading process of the benzene hydrogenation process, during operation, marks the loading and unloading process of the benzene hydrogenation process as the monitoring process, sets several monitoring time points with equal time intervals during the monitoring process, and obtains the risk coefficient FX at the loading and unloading site at the monitoring time point; compares the risk coefficient FX with the risk threshold FXmax, and determines whether the safety risk at the loading and unloading site meets the requirements at the monitoring time point based on the comparison result; obtains the pressure monitoring value and temperature monitoring value at the loading and unloading site, and marks the safety risk factors based on the pressure monitoring value and temperature monitoring value.

[0038] The above content is only an example and explanation of the structure of the present invention. Those skilled in the art of this technology can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, as long as they do not deviate from the structure of the invention or exceed the scope defined by this claim book, they should all fall within the protection scope of the present invention.

[0039] The above formulas are all obtained by collecting a large amount of data for software simulation and selecting a formula close to the true value. The coefficients in the formula are set by those skilled in the art according to the actual situation; for example: the formula FX = k1×BN + k2×TF + k3×JD; those skilled in the art collect multiple groups of sample data and set corresponding risk coefficients for each group of sample data; substitute the set risk coefficients and the collected sample data into the formula, and any three formulas form a system of linear equations with three variables. Screen and take the average value of the calculated coefficients to obtain the values of k1, k2, and k3 as 3.25, 2.51, and 3.37 respectively.

[0040] The magnitude of the coefficient is a specific value obtained by quantifying each parameter for subsequent comparison. Regarding the magnitude of the coefficient, it depends on the amount of sample data and the risk coefficients initially set by those skilled in the art for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantified value, for example, the risk coefficient is proportional to the value of the benzene concentration data.
