Description

Technical Field

[0001] The present invention relates to the technical field of power industry process equipment operation performance prediction, and in particular to a desulfurization equipment operation performance evaluation method, a desulfurization equipment operation performance evaluation system, an electronic device and a computer-readable storage medium. Background Art

[0002] A large amount of coal is burned in the production process of coal-fired power plants, and coal often contains a certain amount of sulfur. After burning, these sulfur elements will release a large amount of SO2. If not managed, it will cause great harm to the environment. For example, sulfur oxides and hydrogen sulfide will pollute the atmosphere, and sulfates and hydrogen sulfide will pollute water bodies. Therefore, desulfurization management of coal-fired power plants is the focus of environmental protection work.

[0003] At present, most coal-fired power plants use the limestone wet flue gas desulfurization (FGD) process to remove SO2 from flue gas. The basic principle of the limestone wet desulfurization process is: limestone powder is added with water to form a slurry as an absorbent and pumped into the absorption tower to fully contact and mix with the flue gas. The sulfur dioxide in the flue gas reacts with the calcium carbonate in the slurry and the air blown in from the bottom of the tower to form calcium sulfate. After the calcium sulfate reaches a certain saturation, it crystallizes to form dihydrate gypsum. The gypsum slurry discharged from the absorption tower is concentrated and dehydrated to make its water content less than 10%, and then it is conveyed to the gypsum storage bin by a conveyor for stacking. The flue gas after desulfurization is passed through a demister to remove droplets, and then heated by a heat exchanger and discharged into the atmosphere through the chimney. Since the absorbent slurry in the absorption tower is repeatedly circulated through a circulating pump to contact with the flue gas, the absorbent utilization rate is very high, the calcium-sulfur ratio is relatively low, and the desulfurization efficiency can be greater than 95%.

[0004] In the above-mentioned limestone wet desulfurization process, a series of equipment used to remove sulfur from coal and prevent the generation of SO2 during combustion can be collectively referred to as desulfurization equipment. There are many types of desulfurization equipment on the current market, and the actual operating performance of desulfurization equipment is also uneven. Accurate evaluation of the operating performance of desulfurization equipment will help coal-fired power plants achieve desulfurization emission standards while reducing the desulfurization process system.

[0005] Operation and maintenance costs.

[0006] However, most of the current desulfurization equipment operating performance evaluation methods are based on the mechanism or experimental model of the desulfurization process, with the help of experimental data of different load sections, and the system performance calculation results are obtained according to the physical and chemical calculation formula. The model given by this method is simple and has low accuracy.

[0038] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0039] Embodiment 1

[0040] Please refer to Figure 1 The first embodiment of the present invention provides a method for evaluating the operating performance of a desulfurization device, the method comprising the following steps:

[0041] Step S101: Acquire actual operation data of the desulfurization equipment.

[0042] It should be noted that the actual operating data of the desulfurization equipment refers to the actual operating data generated by multiple operating parameters of the desulfurization equipment during the actual operation of the desulfurization equipment. The actual operating data of these operating parameters need to be able to fully cover and reflect the actual operating conditions of the desulfurization equipment, and provide rich data support for the subsequent performance evaluation of the desulfurization equipment.

[0043] For example, the actual operation data of the desulfurization equipment may include actual operation data of operation parameters such as slurry pH, sulfur dioxide concentration at the outlet of the desulfurization equipment, sulfur dioxide concentration at the inlet of the desulfurization equipment, actual input power of the desulfurization equipment and actual output power of the desulfurization equipment.

[0044] In addition, actual operation data of several groups of desulfurization equipment can be obtained within a predetermined time range and at predetermined time intervals to ensure that the collected operation data related to the operation parameters are rich and authentic.

[0045] Step S102: Determine the score value of the performance index of the desulfurization equipment based on the actual operation data of the desulfurization equipment.

[0046] It should be noted that the performance indicators of desulfurization equipment should at least include: desulfurization efficiency index, electricity efficiency index and pH control index. The above three performance indicators are important factors affecting the overall operating performance of desulfurization equipment. Among them, the desulfurization efficiency index is used to measure the desulfurization capacity of desulfurization equipment, the electricity efficiency index is used to measure the electric energy conversion capacity of desulfurization equipment, and the pH control index is used to measure the pH control capacity of desulfurization equipment.

[0047] Step S103: Determine the desulfurization equipment operation performance evaluation result based on the score value of the desulfurization equipment performance index and the weight value of the desulfurization equipment performance index.

[0048] According to the above technical scheme, based on the actual operating data of the desulfurization equipment collected, the score values ​​of the desulfurization equipment under different performance indicators can be calculated, and then according to the score values ​​and weight values ​​of these character evaluation indicators, the overall evaluation results of the operating performance of the desulfurization equipment can be obtained, thereby achieving an overall evaluation of the desulfurization equipment.

[0049] Furthermore, in step S102, based on the actual operation data of the desulfurization equipment, the process of determining the score value of the performance index of the desulfurization equipment can be implemented through sub-steps S1021 to S1023.

[0050] Sub-step S1021: Determine the score value of the desulfurization efficiency index based on the sulfur dioxide concentration at the outlet of the desulfurization equipment and the sulfur dioxide concentration at the inlet of the desulfurization equipment.

[0051] Here, the desulfurization efficiency index refers to the percentage of sulfides (such as SO2) removed during the desulfurization process, which is used to evaluate the desulfurization performance of the desulfurization equipment. The calculation formula of the desulfurization efficiency index may vary depending on the desulfurization process and specific conditions. For example, the calculation formula of the desulfurization efficiency index can be:

[0052] Desulfurization efficiency = (sulfur dioxide concentration at the inlet of desulfurization equipment - sulfur dioxide concentration at the outlet of desulfurization equipment) / sulfur dioxide concentration at the inlet of desulfurization equipment.

[0053] In this formula, it is necessary to know the sulfur dioxide concentration at the inlet of the desulfurization equipment and the sulfur dioxide concentration at the outlet of the desulfurization equipment. Usually, these concentrations can be obtained through monitoring and measurement. Substituting these values ​​into the formula, the desulfurization efficiency value can be calculated.

[0054] Sub-step S1022: Determine the score value of the power efficiency index based on the actual input power and the actual output power of the desulfurization equipment.

[0055] Here, the power efficiency index refers to the actual power consumed by the desulfurization equipment during the desulfurization process, which is used to evaluate the power consumption performance of the desulfurization equipment. The power efficiency calculation formula may vary depending on the desulfurization process and specific circumstances. For example, the power efficiency index calculation formula can be:

[0056] Electricity efficiency = actual input power of desulfurization equipment / actual output power of desulfurization equipment.

[0057] In this formula, we need to know the actual input power and output power of the desulfurization equipment. Usually, these powers can be measured by an electric meter or other power measuring equipment. Substituting these values ​​into the formula, we can calculate the value of power efficiency.

[0058] Sub-step S1023: Determine the score value of the pH control index based on the pH value of the slurry and the pH standard range.

[0059] Here, the pH control index refers to the ratio of the number of samples that meet the preset pH standard in the slurry pH value to the total number of samples, which is used to evaluate the qualification of the slurry pH or indicate the effect of slurry pH control. When the ratio is close to 1, it means that most samples meet the pH standard, that is, a high pH compliance rate is achieved.

[0060] It can be determined by judging whether the pH is within the pH standard range. The pH of the slurry within the pH standard range is the qualified pH of the slurry. Then, the number of qualified pHs of the slurry is counted, and its ratio to the total number of pHs of the slurry obtained is calculated, and used as the pH control indicator of the desulfurization equipment.

[0061] The pH value of slurry is an important factor affecting the desulfurization effect of desulfurization equipment. Therefore, for desulfurization equipment, measuring the ability to control pH value is an important part of evaluating the performance of desulfurization equipment.

[0062] Furthermore, in this embodiment, the evaluation method may further include step S104: comparing the desulfurization equipment operation performance evaluation result with a preset operation performance threshold to determine the desulfurization equipment operation performance level.

[0063] For example, multiple operating performance thresholds may be preset, each of which may correspond to a desulfurization equipment operating performance level. By determining which operating performance threshold the desulfurization equipment operating performance evaluation result is within, it is possible to determine which desulfurization equipment operating performance level the current operating state of the desulfurization equipment meets.

[0064] In addition, the implementation environment of this embodiment includes at least one terminal and a server, and the method is executed on the terminal or the server respectively. The terminal and the server can be connected in communication to realize the interactive transmission of information.

[0065] Among them, the terminal can be any electronic product that can interact with the user through one or more methods such as keyboard, touchpad, touch screen, voice interaction, etc., such as PC (Personal Computer), PPC (Pocket Personal Computer), tablet computer, etc.

[0066] The server can be a single server or a server cluster composed of multiple servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), as well as big data and artificial intelligence platforms.

[0067] Embodiment 2

[0068] The second embodiment of the present invention provides another desulfurization equipment operation performance evaluation method, which is applied to a desulfurization equipment operation performance evaluation system. The program code corresponding to the desulfurization equipment operation performance evaluation method is pre-stored in the control center of the desulfurization equipment operation performance evaluation system.

[0069] It should be noted that the desulfurization equipment is mainly composed of flue gas unit, absorption and oxidation unit, lime slurry preparation unit, spray unit, by-product treatment unit, wastewater treatment unit, public unit (including process water, compressed air and accident slurry tank performance evaluation module, etc.) and electrical control unit.

[0070] In the limestone wet desulfurization process, the sulfur-containing flue gas discharged from the boiler induced draft fan is introduced into the desulfurization equipment by the booster fan, and then enters the absorption tower after heat exchange through the gas heater. In the absorption tower, the sulfur-containing flue gas passes through the tower body from bottom to top, and is countercurrently mixed with the mist-like limestone slurry sprayed by the spray unit. The sulfur dioxide in the flue gas reacts with the calcium carbonate in the limestone slurry and the air blown in from the bottom of the tower to form calcium sulfate. After the calcium sulfate reaches a certain saturation, it crystallizes to form dihydrate gypsum. The gypsum slurry discharged from the absorption tower is concentrated and dehydrated to a water content of less than 10%, and then conveyed to the gypsum storage silo by a conveyor for stacking. The desulfurized flue gas passes through the demister to remove the droplets, and then is heated by the heat exchanger and discharged into the atmosphere through the chimney.

[0071] Please refer to Figure 2 A method for evaluating the operating performance of a desulfurization device comprises the following steps:

[0072] Step S201: Acquire actual operation data of the desulfurization equipment.

[0073] Specifically, the sensors pre-installed in the main part of the desulfurization equipment will regularly collect the actual production data of the desulfurization equipment according to the pre-set time period and time interval, that is, the actual operation data of the desulfurization equipment.

[0074] It should be noted that since the desulfurization process of the desulfurization equipment is related to temperature, the temperature may change greatly in a day, so the set time period should include at least three, which are located in the morning, noon and evening of the day. In each time period, the desulfurization equipment operation performance evaluation system obtains the actual operation data of the desulfurization equipment at a predetermined time interval. Then the actual operation data of the desulfurization equipment obtained can be uploaded to the control center of the desulfurization equipment operation performance evaluation system. In this embodiment, various sensors can send a group of actual operation data to the control center of the desulfurization equipment operation performance evaluation system after obtaining a group of actual operation data. It is also possible that after the accumulated data volume of the actual operation data reaches a certain value, the desulfurization equipment operation performance evaluation system will uniformly send the accumulated actual operation data to the control center of the desulfurization equipment operation performance evaluation system.

[0075] The sensors in this embodiment may include: a sulfur dioxide sensor located at the inlet of the absorption tower, a sulfur dioxide sensor located at the outlet of the absorption tower, a pH sensor arranged in the limestone thick slurry tank, and a power sensor for measuring the input power and output power of the desulfurization equipment.

[0076] Therefore, in this embodiment, the actual operation data acquired by the desulfurization equipment operation performance evaluation system may include: the slurry pH of the desulfurization equipment, the sulfur dioxide concentration at the outlet of the desulfurization equipment, the sulfur dioxide concentration at the inlet of the desulfurization equipment, the actual input power of the desulfurization equipment and the actual output power of the desulfurization equipment.

[0077] Step S202: Calculate the score values ​​of the performance indicators of different desulfurization equipment according to the actual operation data of the desulfurization equipment.

[0078] Specifically, the actual operation data of different types of desulfurization equipment are related to the performance indicators of different desulfurization equipment. For example, in this embodiment, the performance indicators that need to be evaluated for the desulfurization equipment include the desulfurization efficiency index, the power efficiency index, and the pH control index. Among them, the desulfurization efficiency index is related to the sulfur dioxide concentration at the outlet of the desulfurization equipment and the sulfur dioxide concentration at the inlet of the desulfurization equipment; the power efficiency index is related to the actual input power of the desulfurization equipment and the actual output power of the desulfurization equipment; the pH control index is related to the desulfurization equipment.

[0079] It is related to the pH value of the concentrated slurry in the limestone concentrated slurry tank.

[0080] After obtaining the actual operating data transmitted by various sensors, the desulfurization equipment operation performance evaluation system will calculate the score values ​​of different desulfurization equipment performance indicators according to the established calculation method.

[0081] Step S203: Calculate the desulfurization equipment operation performance evaluation result according to the score values ​​of different desulfurization equipment performance indicators.

[0082] Specifically, there are three performance indicators for desulfurization equipment. After obtaining the score values ​​corresponding to these three performance indicators, the desulfurization equipment operation performance evaluation system will multiply them by the corresponding weight values ​​respectively, and then add them up to obtain the desulfurization equipment operation performance evaluation result.

[0083] The desulfurization equipment operation performance evaluation result mentioned here refers to the evaluation value of the desulfurization equipment operation performance evaluation system on the overall performance of the desulfurization equipment.

[0084] It should be noted that the weight values ​​corresponding to the performance indicators of the desulfurization equipment are set according to the importance of the performance indicators. The more important the performance indicators are, the greater the corresponding weight values ​​are. In addition, the weight values ​​can be modified by the staff according to the actual operation of the desulfurization equipment, but it is necessary to ensure that the sum of all weight values ​​is 1.

[0085] Step S204: according to the desulfurization equipment operation performance evaluation result, determine the corresponding operation performance level of the desulfurization equipment.

[0086] Specifically, the operating performance levels corresponding to the operating performance evaluation results of different desulfurization equipment may be different. In other words, the operating performance evaluation result corresponding to a performance level should be a range. When the performance evaluation result of the desulfurization equipment falls within a certain range, it means that the performance level of the desulfurization equipment is the performance level within this range.

[0087] The desulfurization equipment operation performance evaluation system is based on the actual operation data of the desulfurization equipment. It uses different performance indicators to score the operation performance of the desulfurization equipment, and then calculates the operation performance evaluation results of the desulfurization equipment according to the score values ​​of different performance indicators, thereby achieving the purpose of evaluating the overall performance of the desulfurization equipment, so that the staff can have a more comprehensive understanding and knowledge of the current desulfurization equipment, and provide data support for the subsequent improvement of certain performance aspects of the desulfurization equipment.

[0088] Furthermore, in this embodiment, the process of calculating the score values ​​of the performance indicators of different desulfurization equipment according to the actual operation data of the desulfurization equipment can be specifically performed in the following sub-steps.

[0089] Sub-step S2021: Calculate the score value of the desulfurization efficiency index based on the sulfur dioxide concentration at the outlet of the desulfurization equipment and the sulfur dioxide concentration at the inlet of the desulfurization equipment.

[0090] Sub-step S2022: Calculate the score value of the power efficiency index according to the actual input power and the actual output power of the desulfurization equipment.

[0091] Sub-step S2023: Calculate the score value of the pH control index according to the pH of the slurry and the pH standard range.

[0092] Furthermore, in this embodiment, in order to more accurately evaluate the desulfurization efficiency of the desulfurization equipment, the process of calculating the score value of the desulfurization efficiency index according to the sulfur dioxide concentration at the outlet of the desulfurization equipment and the sulfur dioxide concentration at the inlet of the desulfurization equipment can be specifically performed as the following sub-steps.

[0093] Sub-step S2021A: Determine several groups of sulfur dioxide concentration data corresponding to the desulfurization equipment.

[0094] Among them, a set of sulfur dioxide concentration data includes: sulfur dioxide concentration at the outlet of desulfurization equipment and sulfur dioxide concentration at the inlet of desulfurization equipment.

[0095] Sub-step S2021B: Substitute the sulfur dioxide concentration at the outlet of the desulfurization equipment and the sulfur dioxide concentration at the inlet of the desulfurization equipment into the desulfurization efficiency calculation formula to obtain several actual desulfurization efficiency values ​​corresponding to the desulfurization equipment.

[0096] The calculation formula of desulfurization efficiency is: desulfurization efficiency = (sulfur dioxide concentration at the outlet of desulfurization equipment - sulfur dioxide concentration at the inlet of desulfurization equipment) / sulfur dioxide concentration at the inlet of desulfurization equipment.

[0097] Sub-step S2021C: determine an average value of a plurality of actual desulfurization efficiency values, and record the average value as a score value of the desulfurization efficiency index corresponding to the desulfurization equipment.

[0098] Since the desulfurization equipment operation performance evaluation system obtains several sets of sulfur dioxide concentration data, the actual desulfurization efficiency value calculated by the desulfurization equipment operation performance evaluation system is not unique. The desulfurization equipment operation performance evaluation system can use the actual desulfurization efficiency value obtained to calculate its average value, and record the calculated average value as the score value corresponding to the desulfurization efficiency index.

[0099] The main task of desulfurization equipment is to separate sulfur dioxide from sulfur-containing flue gas to prevent sulfur-containing flue gas from being discharged into the atmosphere and causing serious air pollution. Therefore, the evaluation of desulfurization efficiency is a very important indicator for desulfurization equipment. The desulfurization equipment operation performance evaluation system measures the desulfurization efficiency of the desulfurization equipment by using the change between the sulfur dioxide concentration at the outlet of the desulfurization equipment and the sulfur dioxide concentration at the inlet of the desulfurization equipment, which can ensure the accuracy and scientificity of the desulfurization efficiency results as much as possible.

[0100] Furthermore, in this embodiment, in order to more accurately evaluate the power efficiency of the desulfurization equipment, the process of calculating the score value of the power efficiency index according to the actual input power and the actual output power of the desulfurization equipment can be specifically performed as the following sub-steps.

[0101] Sub-step S2022A: Determine several groups of power consumption data corresponding to the desulfurization equipment.

[0102] Among them, a set of power consumption data includes: the actual input power of the desulfurization equipment and the actual output power of the desulfurization equipment.

[0103] Sub-step S2022B: Substituting the actual input power and the actual output power of the desulfurization equipment into the power efficiency calculation formula to obtain a number of actual power efficiency values ​​corresponding to the desulfurization equipment.

[0104] The calculation formula for electricity efficiency is: electricity efficiency = actual input power of desulfurization equipment / actual output power of desulfurization equipment.

[0105] Sub-step S2022C: determine an average value of a plurality of actual power efficiency values, and record the average value as a score value of the power efficiency index corresponding to the desulfurization equipment.

[0106] For desulfurization equipment, it is important to convert the input electrical energy into actual work as much as possible and make full use of the electrical energy. Measuring the electricity efficiency of desulfurization equipment can help staff understand the electricity conversion capacity of desulfurization equipment and eliminate some desulfurization equipment with low electricity efficiency, which in turn helps save energy and protect the environment.

[0107] Furthermore, in this embodiment, in order to more accurately evaluate the pH control capability of the desulfurization equipment, the process of calculating the score value of the pH control index according to the slurry pH and the pH standard range can be specifically performed as the following sub-steps.

[0108] Sub-step S2023A: Determine the slurry pH values ​​of several limestone concentrated slurries corresponding to the desulfurization equipment, and record the total number of the slurry pH values ​​as the total pH value.

[0109] Sub-step S2023B: Compare the pH value of each limestone slurry with the endpoint values ​​of the preset pH standard range to determine whether the pH value of each slurry is within the pH standard range.

[0110] For example, the preset pH standard range can be set as 5.2-5.5. If the pH of the limestone concentrate is between 5.2 and 5.5, or the pH of the limestone concentrate is just at a certain endpoint value, it means that the pH of the limestone concentrate is normal and meets the desulfurization process.

[0111] Sub-step S2023C: Count the number of slurry pH values ​​that are within the pH standard range and record it as the pH standard value.

[0112] Sub-step S2023D: Calculate the ratio of the pH value that meets the standard to the total pH value, and determine the ratio as the score of the pH control index.

[0113] The pH value of limestone slurry will change due to many factors. The control unit of the desulfurization equipment will determine whether to add limestone to the limestone slurry pool or reduce the amount of limestone added according to the measured changes in the pH value of the concentrated solution, so as to adjust the pH value of the concentrated solution to meet the pH standard range. Therefore, the ratio of the pH value that meets the standard to the total pH value can more accurately evaluate the desulfurization equipment's ability to control the pH value of the slurry.

[0114] Furthermore, in this embodiment, in order to make the final score value of the pH control index better reflect the control ability of the pH of the desulfurization equipment slurry, after comparing the pH of the slurry with the endpoint value of the preset pH standard range to determine whether the pH of the slurry is within the pH standard range, the following sub-steps may be performed:

[0115] Sub-step S2023E: Determine the slurry pH value that is outside the pH standard range and record it as abnormal pH.

[0116] Sub-step S2023F: traverse all abnormal pH values ​​and determine the adjacent relationship between each abnormal pH value.

[0117] Sub-step S2023G: If there are two abnormal pH values ​​that are adjacent to each other, a deduction value for the pH control index is generated.

[0118] Sub-step S2023H: Count the number of adjacent relationships that determine abnormal pH values ​​and determine the pH value.

[0119] The total deduction value of the degree control index.

[0120] Sub-step S2023I: subtract the total deduction value of the pH control index from the ratio of the pH standard value to the total pH value to update the final score of the pH control index.

[0121] It should be noted that, in the process of obtaining the actual operation data, the desulfurization equipment operation performance evaluation system not only obtains the value of the actual operation data, but also obtains the collection time corresponding to the actual operation data. In the process of traversing the abnormal pH, the desulfurization equipment operation performance evaluation system calculates whether the time difference between the collection times corresponding to the two abnormal pHs is compared with the predetermined time interval. If the two are consistent, the adjacent relationship between the two abnormal pHs can be determined. The desulfurization equipment operation performance evaluation system will count the number of adjacent relationships determined, and when generating the score value corresponding to the pH control index, the product of the predetermined deduction value and the number of adjacent relationships will be subtracted from the original score value to obtain the final score value of the pH control index.

[0122] Among them, the deduction value of the pH control index can be set by the staff according to the actual situation. Since the pH values ​​of the two adjacent slurries are both outside the pH standard range, it can be explained that the control unit of the desulfurization equipment is relatively rough in regulating the amount of limestone and cannot timely regulate the pH value of the limestone slurry within the normal range. Therefore, taking this into account when calculating the performance parameter value can improve the degree of adaptation between the final performance parameter data and the control ability of the desulfurization equipment slurry pH value.

[0123] It should be noted that Figure 2 The flow chart of the desulfurization equipment operation performance evaluation method provided in this embodiment is as follows. It should be understood that although Figure 2The steps in the flowchart are shown in sequence as indicated by the arrows, but the steps are not necessarily executed in the order indicated by the arrows.
