Description

Technical Field

[0001] This invention relates to the field of energy recovery technology, specifically to a high-pressure hydrogen-gas hybrid power generation and carbon dioxide recovery system. Background Technology

[0002] With the continuous growth of global energy demand, the use of traditional fossil fuels has led to significant greenhouse gas emissions, especially carbon dioxide, becoming a major driver of global climate change. Developing clean energy has become a global consensus in response to climate change. High-pressure hydrogen-gas hybrid power generation technology, by mixing hydrogen with carbon-based gases and burning them in a gas turbine, aims to improve power generation efficiency and reduce carbon dioxide emissions. However, existing technologies face the following two main challenges in application:

[0003] First, the dynamic adjustment capability of the fuel ratio is insufficient. During the power generation process, the power demand and combustion state may change. However, the existing system often cannot adjust the ratio of hydrogen to carbon-based gas in real time, which leads to the combustion efficiency not reaching the optimal level, while increasing the amount of carbon dioxide generated and reducing the overall emission reduction effect.

[0004] Secondly, traditional carbon dioxide capture technology usually captures carbon dioxide after combustion. Although carbon dioxide in the exhaust gas can be treated in this process, existing capture methods can often only capture 70% to 90% of the carbon dioxide, making it difficult to achieve complete capture.

[0005] To address the aforementioned shortcomings, a technical solution is provided. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of existing high-pressure hydrogen hybrid power generation technology lacking the ability to dynamically adjust the fuel ratio and the incomplete capture of carbon dioxide, which prevents it from fully realizing its advantages in improving power generation efficiency and reducing carbon emissions in practical applications. Therefore, this invention proposes a high-pressure hydrogen hybrid power generation and carbon dioxide recovery system.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A high-pressure hydrogen-to-carbon dioxide co-generation and carbon dioxide recovery system includes:

[0009] The fuel pretreatment unit is used to monitor the power generation demand status information of the power plant, obtain the power generation demand value, set the fuel ratio parameters based on the power generation demand value, thereby obtaining the pre-prepared fuel, and transport the pre-prepared fuel to the combustion chamber of the gas turbine through the delivery pipeline;

[0010] The pre-combustion capture unit is used to monitor the composition and state information of the prepared fuel in the delivery pipeline, obtain the comprehensive evaluation value of carbon dioxide concentration, and compare and analyze it with the pre-combustion carbon dioxide capture threshold, thereby triggering the carbon dioxide capture command.

[0011] The combustion control unit is used to monitor the combustion status information in the combustion chamber, obtain the combustion stability assessment value, and further adjust the fuel ratio parameters based on the combustion stability assessment value;

[0012] The post-combustion capture unit is used to monitor the composition and state information of the exhaust gas after combustion, obtain the carbon dioxide emission, and compare and analyze it with the post-combustion carbon dioxide capture threshold, thereby triggering the carbon dioxide capture command.

[0013] Furthermore, the specific process for monitoring the power generation demand status information of power plants is as follows:

[0014] By obtaining the power generation plan of the power plant for the current monitoring period;

[0015] Extract the start and end times of power generation from the power generation schedule, and calculate the time difference between the start and end times to obtain the combustion time value Trong.

[0016] Extract the required power generation and power generation efficiency from the power generation plan, and divide the required power generation and power generation efficiency by the result to obtain the fuel energy demand value E. 燃料 ;

[0017] Extracting the calorific value H and fuel energy demand E of the fuel 燃料 The required fuel quantity Qsbng is calculated using the following formula:

[0018] Extract the load value L from the load status parameters of the gas turbine at the power plant corresponding to the current monitoring period. 负荷 Rotational speed N 转速 and runtime value C 时长 According to the formula: Sbnig=L 负荷 ×a1+C 时长 ×a3 / N 转速 ×a2, we get the equipment operating value Sbnig, where a1, a2 and a3 represent the set weight coefficients respectively;

[0019] The values ​​of combustion time (Trong), required fuel quantity (Qsbng), and equipment operating value (Sbnig) are extracted and normalized according to the formula: The power generation demand value EDX is obtained, where Trong & Qsbng & and Sbnig &β1, β2, and β3 represent the reference combustion time, reference required fuel quantity, and reference equipment operating value, respectively, and represent the weighting coefficients of the combustion time, required fuel quantity, and equipment operating value, respectively.

[0020] Furthermore, the specific process for setting the fuel blending parameters is as follows:

[0021] The power generation demand value is matched and analyzed with the power generation demand status table stored in the cloud database to obtain the power generation demand level. At the same time, it is matched with the fuel ratio parameter corresponding to the power generation demand level to obtain the fuel ratio parameter, and a fuel delivery command is triggered to transport the fuel stored in the high-pressure storage tank to the fuel mixing device through the delivery pipeline. According to the set fuel ratio parameter, the fuel is mixed to obtain the prepared fuel.

[0022] Furthermore, the specific process for monitoring the composition and state of the reserve fuel within the delivery pipeline is as follows:

[0023] Multiple detection points are evenly distributed inside the delivery pipeline, and each detection point is equipped with a high-precision component detection instrument.

[0024] During the current monitoring period, the compositional state information of the prepared fuel at each monitoring point is collected using a high-precision compositional analysis instrument. This yields the compositional state information of the prepared fuel at each monitoring point during the current monitoring period, and the hydrogen concentration C at each monitoring point is extracted from this information. 氢气 i Carbon-based gas concentration C 碳基 i and carbon dioxide concentration C 二氧化碳 i According to the formula: The comprehensive carbon dioxide concentration value CCX is obtained, where i represents the number of each detection point, N represents the total number of detection point numbers, and R... 配比 This represents the reference fuel ratio value, and γ1 and γ2 represent the set correction factors, respectively.

[0025] Furthermore, the specific process for monitoring the combustion status information within the combustion chamber is as follows:

[0026] The temperature, pressure and delivery rate in the combustion state information of the combustion chamber corresponding to the current monitoring time period are acquired in real time. The temperature at the first monitoring time point is extracted as the initial temperature, the pressure at the first monitoring time point is extracted as the initial pressure, and the delivery rate at the first monitoring time point is extracted as the initial rate.

[0027] Thus, the temperature fluctuation value δ1, the pressure fluctuation value δ2, and the rate fluctuation value δ3 are obtained;

[0028] The values ​​of temperature fluctuation δ1, pressure fluctuation δ2, and rate fluctuation δ3 are extracted and normalized according to the formula: The combustion stability rating value RSP is obtained, where θ1, θ2 and θ3 represent the weighting coefficients of temperature fluctuation value, pressure fluctuation value and rate fluctuation value, respectively, and θ1 > θ2 > θ3.

[0029] Furthermore, the specific process for further adjusting the fuel blending parameters is as follows:

[0030] The combustion stability assessment value is compared and analyzed with the combustion stability assessment threshold. When the combustion stability assessment value is greater than the preset combustion stability assessment threshold, a combustion anomaly signal is generated.

[0031] Based on the abnormal combustion signal, the combustion stability assessment value is retrieved, and the difference between it and the combustion stability assessment threshold is calculated to obtain the combustion stability assessment difference value.

[0032] The combustion stability assessment difference is then substituted into a preset range of values. Different ranges of values ​​correspond to a fuel ratio control parameter, and a fuel ratio control command is generated. The fuel ratio parameter is then adjusted again according to the fuel ratio control command.

[0033] Furthermore, the specific process for monitoring the compositional state information of the post-combustion exhaust gas is as follows:

[0034] Gas sensors are evenly distributed within the waste gas storage area. These sensors acquire the concentrations of the main components in the waste gas during the current monitoring period. The concentrations of these main components include carbon dioxide, carbon monoxide, nitrogen oxides, and oxygen, and are denoted as FC. 二氧化碳 FC 一氧化碳 FC 氮氧化物 and FC 氧气 According to the formula: Obtain carbon dioxide emissions Q 二氧化碳 Among them, Z FC The total concentration of the main components in the exhaust gas is expressed as: Z FC =FC 二氧氧化 +FC 一氧氧化 +FC 氮氧化物 +FC 氧气 V g This indicates the exhaust gas flow rate.

[0035] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0036] 1. This invention obtains the power generation demand value by real-time monitoring of power generation demand status information, and can dynamically adjust the ratio of hydrogen to carbon-based gas based on the power generation demand value. Secondly, it continuously acquires the temperature, pressure and delivery rate data of the combustion chamber, generates a combustion stability assessment value, and compares and analyzes the combustion stability assessment value to further precisely control the fuel ratio, thereby effectively optimizing the combustion process and significantly improving power generation efficiency.

[0037] 2. This invention also monitors the composition of the pre-fuel to trigger a carbon dioxide capture command, reducing the amount of carbon dioxide entering the combustion chamber at the source, thereby reducing emissions and improving power generation efficiency. At the same time, it monitors the composition of the exhaust gas after combustion and calculates the actual carbon dioxide emissions. By comparing this emission amount with a preset capture threshold, it ensures efficient carbon dioxide capture and significantly reduces environmental pollution. This comprehensive approach provides an effective solution for improving the environmental performance and operational efficiency of power plants. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] like Figure 1 As shown, a high-pressure hydrogen-carbon dioxide hybrid power generation and carbon dioxide recovery system includes: a data acquisition unit, a server, a fuel pretreatment unit, a pre-combustion capture unit, a combustion control unit, a post-combustion capture unit, a display terminal, and a cloud database;

[0042] The data acquisition unit is used to collect power generation demand status information, composition status information and combustion status information, and send them to the fuel pretreatment unit, pre-combustion capture unit, combustion control unit and post-combustion capture unit respectively through the server. The composition status information includes the composition status information of the pre-fuel in the delivery pipeline and the composition status information of the exhaust gas after combustion.

[0043] The cloud database is used to store the power generation demand status table;

[0044] The fuel pretreatment unit is used to monitor the power generation demand status information of the power plant, and thereby analyze and set the fuel blending parameters. The specific analysis process is as follows:

[0045] The power generation plan of the power plant for the current monitoring period is obtained by acquiring the power generation plan of the power plant for the current monitoring period.

[0046] Extract the start and end times of power generation from the power generation schedule, and calculate the time difference between them using the formula: Trong=|T fa -T je |, thus obtaining the combustion time value Trong, where T fa Indicates the start time of power generation, T je Indicates the end time of power generation;

[0047] Extract the required power generation and power generation efficiency from the power generation plan, based on the formula: Obtain the fuel energy demand value E 燃料 Where P represents power generation, which is the planned output of electricity, and M... 发电 Power generation efficiency refers to the ratio of electrical energy output to fuel energy input.

[0048] The required fuel quantity is calculated from the calorific value of the extracted fuel and the fuel energy demand value, using the following formula:

[0049]

[0050] Where Qsbng represents the required amount of fuel, and H represents the calorific value of the fuel;

[0051] By acquiring the load state parameters of the gas turbines at the power plant for the current monitoring period, the load state parameters of the gas turbines at the power plant for the current monitoring period are obtained. The load value, speed value, and operating time value are then extracted from these load state parameters and labeled as L. 负荷 N 转速 and C 时长 According to the formula: Sbnig=L 负荷 ×a1+C 时长×a3 / N 转速 ×a2, we get the equipment operating value Sbnig, where a1, a2 and a3 represent the set weight coefficients respectively;

[0052] It should be noted that the load value refers to the actual output power of the gas turbine, the speed value refers to the speed of the gas turbine during operation, and the running time value refers to the continuous running time of the gas turbine.

[0053] The values ​​of combustion time (Trong), required fuel quantity (Qsbng), and equipment operating value (Sbnig) are extracted and normalized according to the formula: The power generation demand value EDX is obtained, where Trong & Qsbng & and Sbnig & β1, β2, and β3 represent the reference combustion time, reference required fuel quantity, and reference equipment operating value, respectively. β1, β2, and β3 represent the weighting coefficients of the combustion time, required fuel quantity, and equipment operating value, respectively, with β1 > β2 > β3. The weighting coefficients are used to balance the proportion of each data in the formula calculation, thereby improving the accuracy of the calculation results.

[0054] The power generation demand value of the power plant for the current monitoring period is matched and analyzed with the power generation demand status table stored in the cloud database to obtain the power generation demand level of the power plant for the current monitoring period. Each power generation demand value corresponds to a power generation demand level. At the same time, it is matched with the fuel ratio parameter corresponding to the power generation demand level to obtain the fuel ratio parameter of the power plant for the current monitoring period. The fuel ratio parameter includes the ratio of hydrogen to carbon-based gas, such as 70% hydrogen and 30% carbon-based gas. A fuel delivery command is triggered to deliver the hydrogen and carbon-based gas stored in the high-pressure storage tank to the fuel mixing device through independent delivery pipelines. According to the set fuel ratio parameter, the fuel mixing device controls the flow rate through valves to ensure that the hydrogen and carbon-based gas are mixed in the set ratio, thereby obtaining the pre-fuel. At the same time, the pre-fuel is delivered to the combustion chamber of the gas turbine through delivery pipelines.

[0055] The pre-combustion capture unit is used to monitor the composition and state of the prepared fuel in the delivery pipeline, thereby capturing and treating the carbon dioxide in it before combustion. The specific operation process is as follows:

[0056] Multiple detection points are evenly distributed inside the delivery pipeline to ensure coverage of the entire fluid channel of the pipeline. Each detection point is equipped with a high-precision component detection instrument to monitor the gas composition of the prepared fuel in the delivery pipeline in real time.

[0057] During the current monitoring period, the compositional state information of the prepared fuel at each monitoring point is collected using a high-precision compositional analysis instrument. This yields the compositional state information of the prepared fuel at each monitoring point during the current monitoring period, and the hydrogen concentration C at each monitoring point is extracted from this information. 氢气 i Carbon-based gas concentration C 碳基 i and carbon dioxide concentration C 二氧化碳 i According to the formula: The comprehensive carbon dioxide concentration value CCX is obtained, where i represents the number of each detection point, N represents the total number of detection point numbers, and R... 配比 This represents the reference fuel ratio value, and γ1 and γ2 represent the set correction factors, respectively.

[0058] Set the pre-combustion carbon dioxide capture threshold C rounge The carbon dioxide concentration comprehensive evaluation value CCX and the pre-combustion carbon dioxide capture threshold C were compared. rounge Comparative analysis showed that when the comprehensive evaluation value of carbon dioxide concentration (CCX) > the pre-combustion carbon dioxide capture threshold (C) rounge When the carbon dioxide capture command is triggered, the capture device is activated to automatically capture the carbon dioxide in the delivery pipeline and process the captured carbon dioxide into dry ice.

[0059] The combustion control unit is used to monitor the combustion status information in the combustion chamber, thereby adjusting and analyzing the fuel ratio parameters. The specific operation process is as follows:

[0060] The temperature, pressure, and delivery rate in the combustion state information of the combustion chamber for the current monitoring time period are acquired in real time and calibrated as Wd. j Yq j and Sh j Simultaneously, the temperature of the first monitoring time point is extracted from the temperature in the combustion chamber corresponding to the current monitoring time period, and is used as the initial temperature and denoted as Wd0. The pressure of the first monitoring time point is extracted from the pressure in the combustion chamber corresponding to the current monitoring time period, and is used as the initial pressure and denoted as Yq0. The delivery rate of the first monitoring time point is extracted from the delivery rate in the combustion chamber corresponding to the current monitoring time period, and is used as the initial rate and denoted as Sh0. Here, j represents the number of each monitoring time point in the current monitoring time period, and j = 1, 2, 3...m, where m represents the total number of monitoring time point numbers in the current monitoring time period.

[0061] Based on the formula: The temperature fluctuation value δ1 is obtained, where Wd j-1 This represents the temperature at the (j-1)th monitoring time point in the current monitoring period, where u1 and u2 represent preset weighting factors, respectively.

[0062] Based on the formula: The pressure fluctuation value δ2 is obtained, where Yq j-1 This represents the pressure at the (j-1)th monitoring time point in the current monitoring period, and u3 and u4 represent the preset weighting factors, respectively.

[0063] Based on the formula: The rate fluctuation value δ3 is obtained, where Sh j-1 This represents the transmission rate at the (j-1)th monitoring time point in the current monitoring period, where u5 and u6 represent preset weighting factors, respectively.

[0064] The values ​​of temperature fluctuation δ1, pressure fluctuation δ2, and rate fluctuation δ3 are extracted and normalized according to the formula: The combustion stability rating value RSP is obtained, where θ1, θ2 and θ3 represent the weighting coefficients of temperature fluctuation, pressure fluctuation and rate fluctuation, respectively, and θ1 > θ2 > θ3;

[0065] The combustion stability assessment value RSP is compared and analyzed with the preset combustion stability assessment threshold RSY. When the combustion stability assessment value RSP is greater than the preset combustion stability assessment threshold RSY, an abnormal combustion signal is generated; otherwise, a normal combustion signal is generated.

[0066] Based on the combustion anomaly signal, the combustion stability assessment value RSP is retrieved, and the difference between it and the combustion stability assessment threshold RSY is calculated. According to the formula: ΔRS=RSP-RSY, the combustion stability assessment difference ΔRS is obtained.

[0067] The combustion stability assessment difference is substituted into a preset range of values. Different ranges of values ​​correspond to a fuel ratio control parameter, and a fuel ratio control command is generated. Based on the fuel ratio control command, the fuel ratio parameter of the prepared fuel in the current monitoring period is adjusted again to ensure combustion stability and efficiency.

[0068] The post-combustion capture unit is used to monitor the composition and state of the exhaust gas after combustion, and to capture and treat the carbon dioxide in it after combustion. The specific operation process is as follows:

[0069] The exhaust gas from combustion in the combustion chamber is transported to the exhaust gas storage area, where gas sensors are evenly distributed to monitor the composition of the exhaust gas in real time. The concentrations of the main components in the exhaust gas during the current monitoring period are obtained through the gas sensors. These concentrations include carbon dioxide, carbon monoxide, nitrogen oxides, and oxygen, and are denoted as FC. 二氧化碳 FC 一氧化碳 FC 氮氧化物and FC 氧气 According to the formula: Obtain carbon dioxide emissions Q 二氧化碳 Among them, Z FC The total concentration of the main components in the exhaust gas is expressed as: Z FC =FC 二氧氧化 +FC 一氧氧化 +FC 氮氧化物 +FC 氧气 V g Indicates exhaust gas flow rate;

[0070] A post-combustion carbon dioxide capture threshold Cthreld is set. The carbon dioxide emission Qcarbon dioxide is compared and analyzed with the post-combustion carbon dioxide capture threshold Cthreld. When the carbon dioxide emission Qcarbon dioxide > the post-combustion carbon dioxide capture threshold Cthreld, a carbon dioxide capture command is triggered. Based on the triggered carbon dioxide capture command, the capture device is started to automatically capture carbon dioxide in the exhaust gas storage area and make the captured carbon dioxide into dry ice. It can be widely used in various fields. The specific method of making the captured carbon dioxide into dry ice is as follows: the captured carbon dioxide is compressed to a high pressure state, usually to about 5.1 atmospheres, and the compressed carbon dioxide is further cooled by industrial refrigeration equipment to make it into a liquid state. The cooling is usually carried out at about -20℃ to -30℃. After the cooled liquid carbon dioxide is rapidly depressurized, part of it will directly sublimate into gas, absorbing a large amount of heat. The remaining carbon dioxide is then cooled to -78.5℃ to convert it into a solid state, i.e., dry ice. The solid dry ice can be compressed into different shapes, such as dry ice blocks or dry ice granules, through special pressing equipment for convenient use and transportation.

[0071] The display terminal is used to display and notify users of fuel blending parameters and carbon dioxide capture amounts.
