[0020] Reference Figure 1 The embodiment of the present invention discloses a multifunctional and efficient SOFC power generation management method for an island, which includes: S1: Heat diesel to volatilize it into diesel vapor and collect heating parameter information.

[0021] Heating parameter information refers to parameters such as the temperature, fuel intake, and sulfur content associated with diesel heating. This information includes the heating temperature, unit fuel intake, and steam sulfur content. The heating temperature refers to the temperature associated with diesel heating and is obtained by querying the heating device that heats the diesel. The unit fuel intake refers to the amount of diesel introduced per unit time during diesel heating and is obtained by querying the valve opening status of the diesel supply to the heating device. Steam sulfur content is detected and obtained using a sulfur detector pre-installed on the heating device.

[0022] The heating device can be an electrically heated volatilizer, a flame heated volatilizer, a heat carrier heated volatilizer, etc. In this embodiment, the heating device adopts an electrically heated vaporization chamber.

[0023] The sulfur element detection device can be an ultraviolet fluorescence sensor. After the ultraviolet fluorescence sensor irradiates the sulfur oxide to generate fluorescence, the detection and acquisition are performed based on the relationship that the fluorescence intensity is proportional to the sulfur content.

[0024] By passing the diesel into a heating device for heating the diesel, the diesel is volatilized and diesel steam is generated, which facilitates the subsequent cracking and reforming of the diesel.

[0025] S2: Generate suction control information according to the heating parameter information.

[0026] Intake control information refers to the rate and timing of diesel vapor intake by the micro-interface reformer. A micro-interface reformer is a device that breaks up diesel vapor and water vapor into micron-sized bubbles or droplets, cracking and reforming them to produce hydrogen and carbon monoxide. The micro-interface reformer is pre-configured by the operator.

[0027] By processing the heating parameter information, the suction control information is generated, which is convenient for subsequent use. The specific method of generating the suction control information is referred to S21 to S26.

[0028] S3: Based on the intake control information, a preset micro-interface reformer is controlled to inhale water vapor and diesel vapor and perform cracking and reforming to generate a mixed gas.

[0029] Among them, by inputting the suction control information into the preset micro-interface reformer, the preset micro-interface reformer is controlled to inhale water vapor and diesel vapor and perform cracking reforming to generate a mixed gas containing hydrogen and carbon monoxide gas, which facilitates the subsequent use of hydrogen and carbon monoxide gas for power generation.

[0030] S4: Collect the temperature detection value and mixing condition information of the mixed gas.

[0031] The temperature detection value refers to the temperature value corresponding to the mixed gas containing hydrogen and carbon monoxide gases, and the temperature detection value is obtained by detecting through a temperature sensor preset on the micro-interface reformer.

[0032] Mixing information refers to the content and ratio of hydrogen and carbon monoxide in the mixed gas. Mixing information can be obtained by testing with equipment such as a gas chromatograph or an infrared gas analyzer.

[0033] S5: Generate heat transfer control information according to the temperature detection value and the mixing condition information.

[0034] The heat delivery control information refers to the control information used to control the delivery of the mixed gas to the SOFC stack. The SOFC stack is a device used to generate electricity from hydrogen and carbon monoxide gases. The SOFC stack is pre-configured by the operator.

[0035] By analyzing the temperature detection values ​​and mixing information, heat delivery control information is generated to facilitate subsequent use.

[0036] S6: delivering the mixed gas to a preset SOFC stack based on the heat delivery control information to generate electricity.

[0037] Among them, the opening and closing and temperature conditions of the preset input pipeline are controlled by heat delivery control information, so as to deliver the mixed gas to the preset SOFC stack for power generation, thereby accurately controlling the SOFC stack for power generation, thereby reducing the air pollution generated during island power generation.

[0038] The input pipe is pre-arranged on the SOFC stack and is used to input the mixed gas.

[0039] In step S2, in order to further ensure the rationality of the inhalation control information, it is necessary to perform further independent analysis and calculation on the inhalation control information, which is specifically described in detail through the following steps.

[0040] The method for generating the inhalation control information comprises the following steps: S21: Retrieve the heating temperature value and unit oil intake amount based on the heating parameter information.

[0041] Among them, the heating temperature value and unit oil intake volume are retrieved through the heating parameter information to facilitate subsequent use.

[0042] S22: Determine a heating pressure value according to the heating temperature value and the unit oil intake amount.

[0043] The heating pressure value refers to the pressure value corresponding to the diesel vapor formed after the diesel is heated.

[0044] Since heating pressure is positively correlated with heating temperature, the higher the temperature, the stronger the tendency of liquid to evaporate into gas, and the greater the saturated vapor pressure. Furthermore, when conditions such as pipe diameter and fuel viscosity remain unchanged, heating pressure is also positively correlated with unit fuel flow. Therefore, by entering the heating temperature and unit fuel flow into a pre-set heating pressure database, a matching heating pressure value is obtained, facilitating subsequent use.

[0045] The heating air pressure database pre-stores a comparison table of different heating temperature values ​​and unit oil intake and corresponding heating air pressure values. The heating air pressure database obtains and stores the heating air pressure values ​​after the operator pre-tests different heating temperature values ​​and unit oil intake.

[0046] S23: Generate an inhalation rate value and an inhalation time value according to the heating air pressure value.

[0047] Among them, the intake rate value refers to the rate value corresponding to the control of the micro-interface reformer to absorb diesel vapor or water vapor, and the intake time value refers to the time value corresponding to the control of the micro-interface reformer to absorb diesel vapor or water vapor.

[0048] By analyzing the heated air pressure value, the inhalation rate value and inhalation time value are generated for subsequent use.

[0049] The specific method for generating the inhalation rate value and the inhalation time value is described in S231 to S235 .

[0050] S24: Collect the current time point and island location point.

[0051] The current time point refers to the time point corresponding to the current time, and the current time point is obtained by querying a database that counts and stores time in real time.

[0052] The island location point refers to the location of an island where a SOFC stack is used for power generation. The island location point can be obtained by querying a position sensor preset at the SOFC stack, or by pre-entering the island location point by an operator.

[0053] S25: Generate an intake molar ratio according to the unit oil intake amount, the current time point, and the island position point.

[0054] The intake molar ratio refers to the ratio between the molar number of diesel vapor and the molar number of water vapor absorbed into the micro-interface reformer.

[0055] By analyzing the unit oil intake, current time point and island location point, the suction molar ratio is generated for subsequent use.

[0056] The specific method for generating the suction molar ratio refers to S251 to S256.

[0057] S26: Determine intake adjustment information according to the intake rate value, the intake time value, and the intake molar ratio, and use the intake adjustment information as the intake control information.

[0058] The intake adjustment information refers to the control information corresponding to controlling the micro-interface reformer to absorb diesel vapor or water vapor.

[0059] By combining the suction rate value, the suction time value and the suction molar ratio, control information for the suction of diesel vapor or water vapor is formed and used as suction adjustment information, and the suction adjustment information is then used as suction control information, thereby improving the accuracy of the obtained suction control information.

[0060] In step S21, in order to further ensure the rationality of the heating temperature value, it is necessary to perform further separate analysis and calculation on the heating temperature value, which is specifically described in detail through the following steps.

[0061] After the heating temperature value and the unit oil intake amount are retrieved based on the heating parameter information, the following steps are also included: S211: Retrieve the steam sulfur content based on the heating parameter information.

[0062] Among them, steam sulfur content refers to the content of sulfur element in diesel vapor.

[0063] The steam sulfur content is retrieved through heating parameter information for easy subsequent use.

[0064] S212: Determine a unit sulfur content according to the unit oil intake amount.

[0065] The unit sulfur content refers to the maximum sulfur content that can be tolerated during normal evaporation of the diesel fuel corresponding to the unit fuel intake. Different unit fuel intakes correspond to different unit sulfur contents.

[0066] The product value between the unit oil intake and the preset sulfur content benchmark ratio is calculated, and the calculation result is used as the unit sulfur content for subsequent use.

[0067] The sulfur content reference ratio value refers to the ratio value between the unit oil intake amount and the unit sulfur content. The sulfur content reference ratio value is obtained after being pre-input by the operator.

[0068] S213: If the steam sulfur content is greater than the unit sulfur content, determine a sulfur content adjustment value.

[0069] The sulfur content adjustment value refers to the adjustment value corresponding to the sulfur content in diesel vapor.

[0070] When the steam sulfur content is greater than the unit sulfur content, it indicates that the temperature is too high, causing the sulfur content in the diesel vapor to exceed the standard. Therefore, the difference between the steam sulfur content and the unit sulfur content is calculated and the result is used as the sulfur adjustment value for subsequent use.

[0071] S214: Determine a heating adjustment value according to the sulfur content adjustment value.

[0072] The heating adjustment value refers to the adjustment value corresponding to the need to adjust the heating temperature. Different sulfur content adjustment values ​​correspond to different heating adjustment values.

[0073] By inputting the sulfur content adjustment value into a preset heating adjustment database to match the heating adjustment value, subsequent use is facilitated.

[0074] The heating adjustment database pre-stores a comparison table of different sulfur content adjustment values ​​and corresponding heating adjustment values, and the heating adjustment database is obtained after pre-input by an operator.

[0075] S215: Adjust and update the heating temperature value based on the heating adjustment value.

[0076] The heating temperature value is adjusted and updated by the heating adjustment value, thereby improving the accuracy of the obtained heating temperature value, reducing the sulfur content when diesel vapor is obtained based on the heating temperature value, thereby reducing air pollution and improving subsequent power generation efficiency.

[0077] In step S23, in order to further ensure the rationality of the inhalation rate value and the inhalation time value, it is necessary to further analyze and calculate the inhalation rate value and the inhalation time value separately, which is specifically described in detail through the following steps.

[0078] The method for generating the inhalation rate value and the inhalation time value includes the following steps: S231: Obtain device specifications corresponding to the preset micro-interface reformer.

[0079] The device specifications refer to the specifications and models of the micro-interface reformer. The device specifications are obtained by querying the micro-interface reformer.

[0080] S232: Retrieve the suction diameter and suction volume based on the equipment specifications.

[0081] Among them, the suction diameter refers to the diameter of the pipe corresponding to the micro-interface reformer when it sucks diesel vapor, and the suction volume refers to the volume corresponding to the diesel vapor sucked in by the micro-interface reformer when it is reforming.

[0082] The preset specification database is queried through the equipment specifications to match the suction diameter and suction volume, which is convenient for subsequent use.

[0083] The specification database pre-stores a comparison table of different equipment specifications and corresponding suction diameters and suction volumes, and the specification database is obtained after pre-input.

[0084] S233: Determine the suction flow rate value according to the heating air pressure value and the suction diameter.

[0085] The suction flow rate value refers to the flow rate value corresponding to the inhalation of diesel vapor. Different heating pressure values ​​and suction diameters correspond to different suction flow rate values.

[0086] The heating air pressure value and the suction diameter are input into a preset suction flow rate database to match and obtain the suction flow rate value, which is convenient for subsequent use.

[0087] The suction flow rate database pre-stores a comparison table of different heating air pressure values, suction diameters and corresponding suction flow rate values. The suction flow rate database is obtained and stored by the operator after conducting experiments based on different heating air pressure values ​​and suction diameters.

[0088] S234: Generate a flow rate adjustment value according to the suction flow rate value and the equipment specifications.

[0089] The flow rate adjustment value refers to the flow rate value corresponding to the flow rate after adjustment.

[0090] By analyzing the suction flow rate value and equipment specifications, a flow rate adjustment value is generated for subsequent use.

[0091] For the specific method of generating the flow rate adjustment value, refer to S2341 to S2347.

[0092] S235: Determine a required time value according to the inhalation volume and the flow rate adjustment value, and use the required time value as the inhalation time value and the flow rate adjustment value as the inhalation rate value.

[0093] The required time value refers to the time value corresponding to the inhalation of diesel vapor. By calculating the quotient between the inhalation volume and the flow rate adjustment value and using the calculated result as the required time value, the required time value is used as the inhalation time value, and the flow rate adjustment value is used as the inhalation rate value, the accuracy of the obtained inhalation time and inhalation rate values ​​is improved.

[0094] In step S234, in order to further ensure the rationality of the flow rate adjustment value, it is necessary to perform further separate analysis and calculation on the flow rate adjustment value, which is specifically described in detail through the following steps.

[0099] S2342: Determine whether the inhalation flow rate value is less than the maximum flow rate value. If yes, execute S2343; if no, execute S2344.

[0100] Wherein, whether the suction flow rate value needs to be adjusted is determined by judging whether the suction flow rate value is less than the maximum flow rate value.

[0101] S2343: directly using the suction flow rate value as the flow rate adjustment value.

[0102] When the suction flow rate value is less than the maximum flow rate value, it indicates that the suction flow rate value does not need to be adjusted at this time, so the suction flow rate value is directly used as the flow rate adjustment value.

[0103] S2344: Calculate the product value between the suction flow rate value and the preset spiral unit adjustment value and use it as the initial flow rate adjustment value.

[0104] The spiral unit adjustment value refers to the adjustment value corresponding to the suction flow rate when adjusting the suction flow rate using a spiral tube of unit length. The spiral unit adjustment value is obtained through pre-input. The initial flow rate adjustment value refers to the adjustment value corresponding to the initial flow rate adjustment.

[0105] When the suction flow rate value is not less than the maximum flow rate value, it means that the suction flow rate value needs to be adjusted at this time. Therefore, the product value between the suction flow rate value and the preset spiral unit adjustment value is calculated and used as the initial flow rate adjustment value for subsequent use.

[0106] S2345: Calculate the difference between the initial flow rate adjustment value and the maximum flow rate value and use it as the flow rate deviation value.

[0110] The adjustment value refers to the value corresponding to the unit length of the spiral tube. Different flow rate deviation values ​​correspond to different adjustment values.

[0111] By inputting the flow rate deviation value into a preset adjustment number database, the adjustment number value corresponding to the flow rate deviation interval that matches the flow rate deviation interval is obtained, which is convenient for subsequent use.

[0112] The adjustment number database pre-stores different flow rate deviation intervals and corresponding adjustment values. The adjustment number database is tested by an operator according to different adjustment values ​​to obtain the flow rate deviation interval and store it.

[0113] S2347: Determine a final flow rate adjustment value according to the initial flow rate adjustment value, the preset spiral unit adjustment value, and the adjustment value, and use the final flow rate adjustment value as the flow rate adjustment value.

[0114] The final flow rate adjustment value refers to the final adjustment value corresponding to the flow rate after adjustment.

[0115] By inputting the adjustment number value into a preset number adjustment database to match the number adjustment coefficient, then calculating the product value between the number adjustment coefficient and the spiral unit adjustment value to obtain the adjusted number adjustment value, then calculating the product value between the adjusted number adjustment value and the initial flow rate adjustment value to obtain the final flow rate adjustment value, and using the final flow rate adjustment value as the flow rate adjustment value, the accuracy of the obtained flow rate adjustment value is improved.

[0116] The number adjustment database pre-stores different adjustment number values ​​and corresponding number adjustment coefficients, and the number adjustment database is obtained through pre-input.

[0117] In step S25, in order to further ensure the rationality of the inhalation molar ratio, it is necessary to further analyze and calculate the inhalation molar ratio separately, which is specifically described in detail through the following steps.
