Description

Technical Field

[0001] The present invention relates to the field of energy technology, and in particular to a control method for a supporting energy storage system for waste incineration power generation. Background Art

[0002] With the acceleration of urbanization and the improvement of people's living standards, the amount of garbage generated is increasing. Waste incineration power generation, as an effective way of garbage disposal, can generate electricity while achieving garbage reduction and harmlessness. However, the output power of waste incineration power generation is not stable and will be affected by many factors such as garbage composition and incineration conditions.

[0003] At the same time, with the growth of energy demand and the improvement of requirements for grid stability, energy storage technology has gradually received attention. The energy storage system can store excess energy when the power of waste incineration power generation is high, and release energy when the power is low or the grid demand is peak, thereby playing a role in peak shaving and valley filling, balancing supply and demand, improving the grid's ability to accept waste incineration power generation, and ensuring the stable operation of the grid.

[0004] For example, the existing Chinese patent with patent number CN202410458467.4 discloses a garbage pool control method and system for a waste incineration power plant based on artificial intelligence. This scheme realizes the evaluation of the operability of the garbage pool by placing and processing the garbage to be detected stored in the garbage pool and analyzing the relevant parameters. It can accurately judge whether the garbage pool can operate normally. By obtaining the operating process parameters of the garbage pool and comprehensively evaluating them, a comprehensive evaluation of the operating status of the garbage pool is achieved, which helps to discover problems in time and take corresponding control measures. By matching the control scheme and performing corresponding control, the garbage pool is accurately regulated to ensure the stable operation of the waste incineration power plant.

[0005] However, the above patent has the following problems: First, the solution mainly focuses on the evaluation of the operability of the garbage pool, but does not elaborate on whether and how to analyze and consider the availability of calorific value based on the amount and composition of the garbage. It is impossible to accurately optimize the power generation process based on the specific characteristics of the garbage, which may cause energy waste or lack of power generation stability, and is not conducive to more refined and efficient management and utilization of garbage resources.

[0006] Second, the plan focuses on the operability, operating conditions and control of the garbage pool, but the factors affecting the energy conversion of garbage incineration, such as temperature changes and incineration efficiency, are not clearly reflected. This may lead to insufficient control over the overall garbage incineration process and inability to make timely and precise adjustments and optimizations to some problems in the incineration process.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1 As shown, the present invention provides a control method for a supporting energy storage system for waste incineration power generation, the method comprising the following steps: S1. Monitoring of waste processing volume: real-time monitoring of the processing volume of various types of waste for detection.

[0042] See also Figure 2 As shown, the specific analysis method for monitoring the amount of garbage processed is as follows: the first step is to record the sources of the garbage within a set time period, and divide the garbage into several batches according to the sources of the garbage, which are recorded as batches of garbage; after classification into batches, the processing work can be carried out in a more orderly manner to avoid confusion, thereby improving overall efficiency.

[0043] The second step is to classify each batch of garbage one by one according to the set type and record it as different types of garbage; after classification, the processing process can be arranged more efficiently, reducing unnecessary links and costs.

[0044] It should be noted that the classification is divided into recyclables, hazardous waste, kitchen waste and other waste according to the material and purpose of the waste.

[0045] The third step is to set up a scale at the garbage collection point to weigh each type of garbage when it enters the incineration plant, and record it as the amount of garbage processed. This can accurately grasp the actual processing volume of different types of garbage, and reasonably arrange the operation of the incineration plant and resource allocation based on the processing volume of each type of garbage.

[0046] S2. Garbage composition monitoring: monitor the composition parameters of various types of garbage, including organic matter ratio and moisture content.

[0047] The specific analysis method of the garbage composition monitoring is as follows: the first step is to read the amount of garbage processed by each type, recorded as , Indicates The number of the garbage category, , two set amounts of garbage are selected from each type of garbage treatment volume as sampling samples, which are recorded as various types of garbage organic matter samples and various types of garbage moisture content samples, and various types of garbage organic matter samples are weighed and recorded as , burn various types of garbage organic matter samples, and weigh them again after the burning time is set, recorded as , through the formula Get the organic matter ratio of each type of garbage Accurately understanding the organic matter content in garbage and better evaluating the potential of recyclable resources will help to improve waste incineration and other treatment processes in a targeted manner and improve treatment effects and efficiency.

[0048] In the second step, the moisture content samples of various types of garbage are weighed at the same time, recorded as , put various types of garbage moisture content samples into the oven, set the oven to a fixed temperature, and take several time points at the set time intervals, and conduct real-time detection of the weight of various types of garbage moisture content samples at each time point when drying at a fixed temperature, and record it as the moisture content sample weight of various types of garbage at each time point , substituting it into the formula Get the difference in moisture content sample volume between each time point and the previous time point for each type of garbage , Indicates The number of the time point, , select the minimum value from the difference between the moisture content sample quantity of each type of garbage at adjacent time points and the previous time point, record the time point corresponding to the minimum difference between the moisture content sample quantity of each type of garbage and the previous time point as the drying time point of each type of garbage, and extract the moisture content sample quantity corresponding to the drying time point of each type of garbage from the moisture content sample quantity of each type of garbage at each time point, and record it as , through the formula Get the moisture content of various types of garbage ; According to accurate moisture content information, adjust the parameters of waste incineration and other treatment processes to improve treatment efficiency and effects, ensure stable quality during waste treatment, and avoid substandard treatment due to moisture content problems.

[0049] It should be noted that the setting of fixed temperature in garbage drying usually takes into account the composition and characteristics of the garbage, as well as the performance of the drying equipment. Under normal circumstances, when calculating the moisture content of garbage drying, the fixed drying temperature is set at around 105°C.

[0050] S3. Analysis of garbage calorific value: The availability of garbage calorific value is obtained based on the processing volume and component parameters of each type of garbage.

[0051] The specific analysis method of the garbage calorific value analysis is: read the treatment amount of each type of garbage respectively , organic matter ratio , moisture content , substituting it into the formula Get the available calorific value of garbage , They represent the weight factors of the set garbage processing volume, organic matter ratio, and moisture content, respectively. Indicates the set reference value of garbage disposal volume. Indicates the number of garbage classifications. Represents a natural constant; it can more accurately understand the available value of different types of garbage, so as to better plan resource recovery and utilization strategies, reasonably arrange treatment methods and processes according to the available calorific value of garbage, and improve overall treatment efficiency.

[0052] It should be noted that, in a specific embodiment, It can be set to 0.2. It can be set to 0.3. It can be set to 0.5. The moisture content has a greater impact on the availability of the calorific value of garbage. A higher moisture content will reduce the calorific value of the garbage because the evaporation of water will consume heat. Therefore, to a certain extent, the weight of the moisture content may be relatively large. A high organic matter content usually means a higher potential calorific value. The amount of garbage processed may not have as much direct impact on the availability of calorific value as the first two, but in some large-scale garbage treatment scenarios, it may also have a certain impact on the overall effect. Therefore, the moisture content has the highest weight.

[0053] S4. Incineration operation monitoring: monitor the operating status parameters of the incinerator, including the uniformity of furnace temperature distribution, the degree of furnace pressure compliance, and the degree of vibration impact of the incinerator.

[0054] The specific analysis method of the combustion operation monitoring is as follows: the first step is to select a number of position points in the furnace according to the set distance, which are recorded as test points, and at the same time, select a number of time points with equal time intervals during the combustion process, which are recorded as combustion time points, and use an infrared thermometer to detect the temperature of each combustion time point at each test point in the furnace, which is recorded as , Indicates The number of the test point, , Indicates The number of the burning time point, The average temperature of each test point in the furnace is obtained by taking the average temperature of each test point at each burning time point, which is recorded as , substituting it into the formula Get the uniformity of furnace temperature distribution , represents the number of test points, Indicates the number of incineration time points; according to the uniformity of furnace temperature distribution, adjust the incineration process parameters, such as air supply, to ensure a more stable and efficient incineration effect.

[0055] The second step is to connect the pressure gauge to the furnace and use the pressure gauge to detect the pressure in the furnace at each burning time point, which is recorded as , the pressure in the furnace at each burning time point is compared with the preset pressure threshold, and the burning time point at which the pressure in the furnace is greater than the preset pressure threshold is recorded as an abnormal time point, and the number of abnormal time points is counted and recorded as , through the formula Get the furnace pressure qualification level , Respectively represent the weight factors of pressure stability and number of abnormal time points, Indicates the number of incineration time points; can keep track of changes in furnace pressure at any time, detect pressure anomalies in time, avoid safety accidents caused by excessively high or low pressure, help maintain the furnace within a suitable pressure range, and reduce the risk of equipment failure.

[0056] It should be noted that, in a specific embodiment, It can be set to 0.6. It can be set to 0.4. The pressure stability has a greater impact on the furnace pressure qualification, because a continuous and stable pressure state is a key factor in ensuring the normal operation and safety of the furnace. The number of abnormal time points is also important. If there are more abnormal time points, it means that the frequency of furnace pressure problems is high, which will have a greater impact on the qualification. But relatively speaking, its weight may be slightly lower than that of the pressure stability. Therefore, the weight corresponding to the pressure stability is higher.

[0057] The third step is to divide the incineration process into several time periods of equal length. The vibration frequency of the incinerator in each time period is counted by the vibration sensor. The vibration frequency of the incinerator in each time period is obtained by dividing the vibration frequency of the incinerator in each time period by the length of each time period, which is recorded as , Indicates The number of the time period, , and read the amplitude of each vibration in each time period, recorded as , Indicates The number of vibrations, , through the formula Get the vibration impact of the incinerator , Respectively represent the weight factors of the set vibration frequency and vibration amplitude, Indicates the number of vibrations. Indicates the number of time periods, Indicates the reference value of vibration frequency; it can detect abnormal vibration in time, prevent equipment damage or failure due to excessive vibration, and avoid cumulative damage to equipment caused by long-term adverse vibration.

[0058] It should be noted that, in a specific embodiment, It can be set to 0.4. It can be set to 0.6. A larger vibration amplitude may have a more direct and significant impact on the stability, safety and life of the equipment. The vibration frequency is also important, but relatively speaking, its overall impact on the incinerator may not be as prominent as the vibration amplitude. Therefore, the weight corresponding to the vibration amplitude is higher.

[0059] S5. Incineration operation analysis: The operation evaluation coefficient of the incinerator is obtained based on the operation status parameter analysis of the incinerator.

[0060] The specific analysis method of the incineration operation analysis is to read the uniformity of the furnace temperature distribution respectively: , Pressure qualification level , Vibration Impact , substituting it into the formula Get the incinerator operation evaluation coefficient , The weight factor that represents the uniformity of temperature distribution, pressure compliance, and vibration impact. Represents a natural constant; by integrating the uniformity of temperature distribution, the degree of pressure compliance and the degree of vibration influence, it can more comprehensively reflect the overall operating status of the incinerator, help to promptly discover potential problems and ensure the safe operation of the incinerator.

[0061] It should be noted that, in a specific embodiment, It can be set to 0.4. It can be set to 0.4. It can be set to 0.2. Uneven temperature distribution may lead to a series of problems such as incomplete incineration and local overheating, which will seriously affect the performance and operation of the incinerator. The impact of pressure qualification is also relatively large. Appropriate pressure is crucial to the stability and safety of the incineration process. The importance of vibration impact may be relatively small, but if the vibration is too severe or abnormal, it will also cause damage to the equipment. Therefore, the weights corresponding to the uniformity of temperature distribution and the degree of pressure qualification are equal, and the weight corresponding to the vibration impact is lower.

[0062] S6. Combustion control monitoring: monitor the combustion control parameters of the incinerator, including the degree of air supply qualification, oxygen content at each combustion time point, and combustion speed.

[0063] The specific analysis method of the combustion control monitoring is: install air volume measurement devices in the primary air and secondary air ducts, read the air volume values ​​of the primary air and secondary air at each burning time point, and record them as , substituting it into the formula Get the air supply level of the incinerator , Respectively represent the reference values ​​of the set primary and secondary air volume. It represents the number of incineration time points. At the same time, the furnace is divided into several areas. At each incineration time point, a set amount of gas is extracted from each area in the furnace. After cooling, the oxygen concentration is measured using an oxygen sensor to obtain the oxygen content of each area at each incineration time point in the incinerator. The oxygen content of each incineration time point in the incinerator is obtained by taking the average value, which is recorded as , the feed amount of the incinerator in each time period is obtained by weighing, recorded as , and at the same time obtain the discharge amount of the residue after incineration in each time period, recorded as , and record the time period as , through the formula Get the combustion rate of the incinerator , Indicates the number of time periods; based on air volume measurement and the degree of air supply qualification, it can accurately adjust primary and secondary air to optimize combustion effects, ensure appropriate air supply, promote full combustion of fuel, reduce energy waste, and maintain appropriate oxygen content in the furnace through oxygen concentration monitoring to make combustion more stable and complete.

[0064] It should be noted that the main function of primary air is to transport fuel into the furnace and provide oxygen for the initial combustion of the fuel, while the main function of secondary air is to further supplement the oxygen required for combustion, promote the full combustion of the fuel, and at the same time disturb the airflow and make the combustion more uniform and stable.

[0065] It should be noted that, in a specific embodiment, in a specific pulverized coal furnace, when the amount of pulverized coal fuel is 10 tons per hour, the wind speed of the primary air is set to 20 meters per second, and the air volume is about 8,000 cubic meters per hour to ensure that the pulverized coal can be effectively transported and initially burned. In terms of combustion conditions, the flue gas analyzer detects that the oxygen content in the furnace is 8%, which is lower than the 10% required for optimal combustion. At this time, it is necessary to increase the secondary air. Assuming that the secondary air speed is adjusted to 35 meters per second and the air volume is increased to 12,000 cubic meters per hour, after a period of time, it is found that the oxygen content has risen to 9.5% after another test, and the combustion is more complete and stable.

[0066] S7. Combustion control analysis: The combustion control evaluation coefficient of the incinerator is obtained based on the combustion control parameter analysis of the incinerator.

[0067] The specific analysis method of the combustion control analysis is: read the air supply qualification of the incinerator respectively , oxygen content at each incineration time point , Burning speed , substituting it into the formula Obtain the combustion control evaluation coefficient of the incinerator , They represent the weight factors of the set air supply qualification, oxygen content, and combustion speed respectively. Indicates the preset oxygen content and combustion speed reference value. Indicates the number of incineration time points; by paying attention to factors such as air supply, oxygen content and incineration speed, ensuring good combustion results, it helps to achieve a more efficient incineration process and reduce costs.

[0068] It should be noted that, in a specific embodiment, It can be set to 0.4. It can be set to 0.4. It can be set to 0.2. The oxygen content directly affects the sufficiency and efficiency of combustion, and plays a key role in the combustion effect of the incinerator. The appropriate air supply is closely related to the oxygen content and has a greater impact on the stability of combustion. Therefore, the air supply and oxygen content have higher corresponding weights.

[0069] S8. Waste-to-energy analysis: The performance evaluation index of waste-to-energy is obtained based on the availability of waste calorific value, the operation evaluation coefficient of the incinerator, and the combustion control evaluation coefficient.

[0070] The specific analysis method of the waste power generation analysis is: reading the availability of waste calorific value respectively , Incinerator operation evaluation coefficient , Combustion control evaluation coefficient , substituting it into the formula Get the performance evaluation index of waste-to-energy , They represent the weight factors of the set garbage calorific value availability, the incinerator operation evaluation coefficient, and the combustion control evaluation coefficient. Represents a natural constant; it can accurately measure the impact of various key factors in waste-to-energy on energy conversion efficiency, promote more full and efficient utilization of waste resources, and improve power generation efficiency.

[0071] It should be noted that, in a specific embodiment, It can be set to 0.4. It can be set to 0.4. It can be set to 0.2. Whether the incinerator is in good operating condition is directly related to whether the entire energy conversion process can be carried out efficiently and stably, including the normal operation of the equipment, energy utilization efficiency, etc. The availability of the calorific value of garbage largely determines the quality and availability of the initial energy. The importance of the combustion control evaluation coefficient is relatively smaller, but it also has a direct impact on the energy conversion efficiency, such as affecting the sufficiency and stability of combustion. Therefore, the weights corresponding to the availability of the calorific value of garbage and the operation evaluation coefficient of the incinerator are relatively high.

[0072] S9. Power balance judgment: Compare the performance evaluation index of waste-to-energy with the preset performance evaluation index threshold to determine whether the energy storage system needs to intervene.

[0073] See also Figure 3 As shown, the specific analysis method for power balance judgment is: reading the performance evaluation index of garbage power generation, comparing the performance evaluation index of garbage power generation with the preset performance evaluation index, if the performance evaluation index of garbage power generation is greater than or equal to the preset performance evaluation index, it means that the performance of garbage power generation conversion is qualified and no energy storage system intervention is required; if the performance evaluation index of garbage power generation is less than the preset performance evaluation index, it means that the performance of garbage power generation conversion is unqualified and the energy storage system intervention is required to provide feedback to the system; it can be decided in time whether the energy storage system intervention is needed according to the actual situation to achieve reasonable allocation and utilization of energy, ensure that garbage power generation can better meet the needs of the power grid, and maintain the stability and reliability of power supply.

[0074] The present invention obtains the availability of the calorific value of garbage according to the processing volume and component parameters of various types of garbage, obtains the operation evaluation coefficient of the incinerator according to the operation status parameter analysis of the incinerator, obtains the combustion control evaluation coefficient of the incinerator according to the combustion control parameter analysis of the incinerator, obtains the performance evaluation index of garbage power generation according to the availability of the calorific value of garbage, the operation evaluation coefficient of the incinerator and the combustion control evaluation coefficient, and compares the performance evaluation index of garbage power generation with a preset performance evaluation index threshold to determine whether the energy storage system needs to intervene, thereby improving the stability and reliability of power grid operation and enabling garbage power generation and the power grid to work better in coordination.
