[0029] See also Figure 1 , Figure 1 This is a structural diagram of a high-temperature fuel gas dust removal and fuel gas delivery system provided in an embodiment of the present application. As shown in the figure, the system includes: a circulating fluidized bed gasifier, a dust collector, a delivery pipeline and a gas boiler, wherein:

[0030] The circulating fluidized bed gasifier is configured to obtain first attribute information of target biomass, obtain a target operating mode of the gas boiler, determine first operating parameters corresponding to the first attribute information and the target operating mode, control the circulating fluidized bed gasifier to operate according to the first operating parameters, and convert the target biomass into first high-temperature fuel gas, which is fed into the dust collector; the first high-temperature fuel gas is fuel gas having a temperature within a first preset temperature range;

[0031] The dust collector is configured to obtain second attribute information of the first high-temperature fuel gas, determine a second preset temperature range corresponding to the second attribute information, determine second operating parameters corresponding to the second attribute information, control the temperature of the dust removal environment within the second preset temperature range, and control the dust collector to remove dust from the first high-temperature fuel gas using the second operating parameters to obtain second high-temperature fuel gas;

[0032] The delivery pipeline is used to deliver the second high-temperature fuel gas to the gas boiler so that the second high-temperature fuel gas is burned by the gas boiler.

[0033] The target biomass may include at least one of the following: crops (rice straw, wheat straw, bean straw, cotton straw, straw, husk, etc.), wood, algae, weeds, etc., without limitation. The target biomass is a biomass raw material that has been crushed.

[0034] The first attribute information may include at least one of the following: biomass type, biomass quality, biomass dryness, biomass crushing degree, biomass density, biomass origin, biomass purity, etc., which are not limited here.

[0035] The first high-temperature fuel gas may include at least one of the following: carbon monoxide (CO), hydrogen (H2), methane (CH4), etc., without limitation herein. The second high-temperature fuel gas may also include at least one of the following: carbon monoxide (CO), hydrogen (H2), methane (CH4), etc., without limitation herein.

[0036] The first operating parameter may include at least one of the following: operating current, operating voltage, operating power, operating temperature, operating pressure, air supply efficiency, fluidization velocity, etc., without limitation. In a specific implementation, the target biomass is fluidized at high speed within a circulating fluidized bed gasifier, achieving intense mass and heat transfer, undergoing pyrolysis and gasification to generate combustible gas, namely, the first high-temperature fuel gas. High speed refers to a velocity greater than a preset value, which can be pre-set or set by the system default.

[0037] In the embodiment of the present application, the first preset temperature range can be preset or set by system default. The temperature of the first high-temperature fuel gas is within the first preset temperature range.

[0038] In the specific implementation, the first attribute information of the target biomass can be obtained, and the target working mode of the gas boiler can also be obtained. Different working modes have different energy requirements. Therefore, the first working parameters corresponding to the first attribute information and the target working mode can be determined, and the circulating fluidized bed gasifier can be controlled to operate with the first working parameters, and the target biomass can be converted into the first high-temperature fuel gas, and the first high-temperature fuel gas can be sent to the dust collector. On the one hand, the working parameters of the circulating fluidized bed gasifier can be dynamically determined based on the characteristics of the biomass and the needs of the gas boiler, so that the working parameters of the circulating fluidized bed gasifier are more in line with the characteristics of the biomass itself and the actual needs of the gas boiler. On the other hand, the first high-temperature fuel gas can be sent to the dust collector to further improve the purity of the combustible gas, thereby improving the combustion efficiency.

[0039] In specific implementation, nitrogen can be used to control the temperature in the circulating fluidized bed gasifier to achieve a reasonable temperature distribution in the furnace, ensure normal gasification of biomass, and reduce biomass slagging. The zero pressure point can also be reasonably set to maintain a slight negative pressure at the biomass feeding port to avoid gas leakage outside the furnace and cause danger.

[0040] Among them, the dust collector may include: a cyclone separator and a dust separator. In specific implementation, since the high-temperature fuel gas generated by biomass gasification carries a large amount of ash, the fuel gas is initially purified by the cyclone separator and the dust separator under high temperature conditions. The fuel gas temperature at the outlet of the biomass furnace can be 700-750°C.

[0041] The second attribute information may include at least one of the following: gas composition, dust distribution density, dust particle size, gas density, gas mass ratio, etc., without limitation. The gas mass ratio of the first high-temperature fuel gas = gas mass in the first high-temperature fuel gas / (gas mass in the first high-temperature fuel gas + solid mass in the first high-temperature fuel gas).

[0042] Among them, the gas mass ratio value reflects the chemical reaction efficiency to a certain extent, that is, the chemical reaction efficiency refers to the degree of reaction, which can be specifically understood as the maximum conversion rate of a reaction from reactants to products.

[0043] The second operating parameter may include at least one of the following: operating current, operating voltage, operating power, dust removal mode, etc., which are not limited here.

[0044] In an embodiment of the present application, the dust collector can obtain second attribute information of the first high-temperature fuel gas, and can pre-store a mapping relationship between the preset attribute information and the temperature range. Then, the second preset temperature range corresponding to the second attribute information can be determined based on the mapping relationship. Then, the appropriate dust removal temperature can be adapted based on the characteristics of the high-temperature fuel gas. Then, the mapping relationship between the preset attribute information and the working parameters can be pre-stored, and the second working parameters corresponding to the second attribute information can be determined based on the mapping relationship. That is, the corresponding working parameters can be adapted based on the characteristics of the high-temperature fuel gas, and the temperature of the dust removal environment can be controlled within the second preset temperature range. The dust collector can be controlled to remove dust from the first high-temperature fuel gas with the second working parameters to obtain the second high-temperature fuel gas. In this way, the appropriate dust removal temperature and the corresponding working parameters are adapted based on the characteristics of the high-temperature fuel gas, and the dust removal effect of the high-temperature fuel gas can be guaranteed, the purity of the high-temperature fuel gas can be improved, and the combustion effect of the high-temperature fuel gas can be improved, that is, the utilization efficiency of biomass energy can be improved.

[0045] In the embodiment of the present application, the second high-temperature fuel gas can be transported to the gas boiler through a transport pipeline, so that the second high-temperature fuel gas is burned by the gas boiler, thereby completely converting the biomass into energy.

[0046] Among them, the conveying pipeline can include a heat-resistant alloy steel plate pipeline. In a specific implementation, air can also be sent into the circulating fluidized bed gasification furnace by the blower. Specifically, the air is blown into the riser to improve the gasification effect of the circulating fluidized bed gasification furnace. Then, the generated 750°C high-temperature fuel gas can be sent to the dust collector. The high-temperature fuel gas after dust removal is sent to the gas boiler for combustion through the heat-resistant alloy steel plate pipeline.

[0047] Optionally, in determining the second preset temperature range corresponding to the second attribute information, the dust collector is specifically configured to:

[0048] determining a reference temperature range corresponding to the second attribute information, the reference temperature range including an upper threshold and a lower threshold;

[0049] Acquire third attribute information of the delivery pipeline, wherein the third attribute information includes the following attribute information: delivery pipeline length, delivery pipeline material, and delivery pipeline structure;

[0050] adjusting the upper threshold according to the third attribute information to obtain a target upper threshold;

[0051] Obtaining historical dust removal efficiency values ​​of the dust collector to obtain multiple historical dust removal efficiency values;

[0052] Adjusting the lower threshold according to the multiple historical dust removal efficiency values ​​to obtain a target lower threshold;

[0053] The second preset temperature range is determined according to the target lower threshold and the target upper threshold.

[0054] In an embodiment of the present application, a mapping relationship between preset attribute information and temperature range can be pre-stored, that is, different high-temperature gases have different characteristics, and thus, the corresponding dust removal temperature can be adapted based on their corresponding characteristics. Furthermore, a reference temperature range corresponding to the second attribute information can be determined based on the mapping relationship, and the reference temperature range includes an upper threshold and a lower threshold.

[0055] The third attribute information may include at least one of the following: length of the delivery pipeline, diameter of the delivery pipeline, material of the delivery pipeline, structure of the delivery pipeline, etc., which are not limited here.

[0056] Next, the third attribute information of the transmission pipeline can be obtained. The third attribute information includes the following attribute information: transmission pipeline length, transmission pipeline material and transmission pipeline structure. The third attribute information reflects the characteristics of the transmission pipeline. Since the temperature of the gas will also attenuate to a certain extent during the gas transmission process, the upper limit threshold can be adjusted according to the third attribute information to obtain the target upper limit threshold. Then, it can be ensured that the second high-temperature gas has the optimal combustion temperature, thereby improving the utilization efficiency of biomass energy.

[0057] Of course, it is also possible to obtain the historical dust removal efficiency value of the dust collector and obtain multiple historical dust removal efficiency values. The historical dust removal efficiency value reflects the dust removal capacity of the dust collector to a certain extent. Then, the lower limit threshold can be adjusted according to the multiple historical dust removal efficiency values ​​to obtain the target lower limit threshold, that is, the dust removal capacity defects of the equipment itself can be compensated by increasing the lower limit temperature range of the dust collector. Then, the dust removal efficiency can be improved to a certain extent, which also helps to ensure the subsequent combustion temperature effect of the second high-temperature fuel gas, and then improve the utilization efficiency of biomass energy. The second preset temperature range is then determined based on the target lower limit threshold and the target upper limit threshold.

[0058] In this way, in the embodiment of the present application, the temperature attenuation of the transmission pipeline characteristics is taken into consideration, and the dust removal temperature is dynamically adjusted, which not only ensures the dust removal effect, but also ensures that the second high-temperature fuel gas has the optimal combustion temperature, thereby improving the utilization efficiency of biomass energy. In addition, considering the dust removal capacity of the dust collector, the dust removal capacity defects of the equipment itself are compensated by increasing the lower limit temperature range of the dust collector, thereby improving the dust removal efficiency to a certain extent, and also helping to ensure the subsequent combustion temperature effect of the second high-temperature fuel gas, thereby improving the utilization efficiency of biomass energy, so that the final dust removal temperature control range depth is consistent with the high-temperature fuel gas dust removal and fuel gas transmission system structure and improves the biomass energy conversion efficiency.

[0059] Optionally, in the aspect of adjusting the upper threshold according to the third attribute information to obtain a target upper threshold, the dust collector is specifically configured to:

[0060] determining a target temperature attenuation parameter corresponding to the third attribute information;

[0061] determining a predicted combustion temperature according to the upper threshold and the target temperature attenuation parameter, the predicted combustion temperature being a predicted temperature of the second high-temperature fuel gas delivered to the gas boiler;

[0062] obtaining a first ideal combustion temperature of the first high-temperature fuel gas;

[0063] determining a first deviation between the predicted combustion temperature and the first desired combustion temperature;

[0064] determining a first adjustment parameter corresponding to the first deviation;

[0065] The upper threshold is adjusted upward according to the first adjustment parameter to obtain the target upper threshold.

[0066] In this embodiment of the present application, a mapping relationship between preset attribute information and temperature attenuation parameters can be pre-stored. Based on this mapping relationship, a target temperature attenuation parameter corresponding to the third attribute information can be determined. This allows for dynamic and accurate assessment of temperature attenuation based on the characteristics of the pipeline. The temperature attenuation parameter ranges from 0 to 0.1.

[0067] Among them, a mapping relationship between preset attribute information and ideal combustion temperature can be pre-stored, and then, based on the mapping relationship, the first ideal combustion temperature corresponding to the second attribute information can be determined. That is, the characteristics of the high-temperature fuel gas are different, so its ideal combustion temperature is different. Since the high-temperature fuel gas itself may be a mixed gas, its composition and impurity content are different, which may affect the optimal combustion temperature.

[0068] Next, the predicted combustion temperature can be determined based on the upper threshold and the target temperature attenuation parameter. The predicted combustion temperature is the predicted temperature of the second high-temperature gas delivered to the gas boiler. The predicted combustion temperature = (1 - target temperature attenuation parameter) * upper threshold. Alternatively, the first ideal combustion temperature of the first high-temperature gas can be obtained. The first deviation between the predicted combustion temperature and the first ideal combustion temperature can be determined. The first deviation = (first ideal combustion temperature - predicted combustion temperature) / first ideal combustion temperature. The deviation reflects, to a certain extent, the deviation between the predicted and ideal combustion temperatures of the high-temperature gas. The predicted combustion temperature is lower than the first ideal combustion temperature.

[0069] Furthermore, a mapping relationship between a preset deviation and an adjustment parameter can be pre-stored, and then, based on the mapping relationship, a first adjustment parameter corresponding to the first deviation can be determined, and then the upper limit threshold can be increased according to the first adjustment parameter to obtain a target upper limit threshold, that is, the target upper limit threshold = (1 + first adjustment parameter) * upper limit threshold. That is, considering that the characteristics of the transmission pipeline will cause temperature attenuation, the temperature attenuation can be dynamically and accurately evaluated based on the characteristics of the transmission pipeline, and then the upper limit temperature of the temperature control can be dynamically adjusted in combination with the difference between the predicted temperature of the high-temperature gas reaching the gas boiler and the ideal combustion temperature. This can not only make the final dust removal temperature control range, but also can combine the temperature loss of the transmission pipeline to ensure the temperature of the high-temperature gas, improve the activity of the high-temperature gas, ensure the gas combustion efficiency, and improve the biomass energy conversion efficiency.

[0070] Optionally, in the step of obtaining a historical dust removal efficiency value of the dust collector and obtaining a plurality of historical dust removal efficiency values, the dust collector is specifically configured to:

[0071] Obtaining a work log of the dust collector, wherein the work log records a plurality of reference historical dust removal efficiency values, each reference historical dust removal efficiency value corresponds to a gas state parameter, and the gas state parameter includes a gas composition value and a dust condition value;

[0072] Acquire current gas state parameters of the first high-temperature gas, where the current gas state parameters include a current gas composition value and a current dust condition value;

[0073] matching a current gas state parameter of the first high-temperature gas with a gas state parameter corresponding to each reference historical dust removal efficiency value in the plurality of reference historical dust removal efficiency values ​​to obtain a plurality of matching values;

[0074] A target matching value greater than a preset threshold is selected from the multiple matching values, and a historical dust removal efficiency value corresponding to the target matching value is obtained to obtain the multiple historical dust removal efficiency values.

[0075] The preset threshold can be pre-set or set by system default. The dust condition value is used to describe the dust content, shape, etc. in the high-temperature fuel gas. The historical dust removal efficiency value can be understood as the historical dust removal capacity.

[0076] In an embodiment of the present application, a work log of the dust collector can be obtained. The work log records multiple reference historical dust removal efficiency values, each of which corresponds to a gas state parameter, including a gas composition value and a dust condition value. The current gas state parameter of the first high-temperature gas can also be obtained, including a current gas composition value and a current dust condition value. The current gas state parameter of the first high-temperature gas is then matched with the gas state parameter corresponding to each reference historical dust removal efficiency value in the multiple reference historical dust removal efficiency values ​​to obtain multiple matching values. A target matching value greater than a preset threshold is selected from the multiple matching values, i.e., the target matching value indicates that the historical high-temperature gas is similar to the first high-temperature gas, and therefore the dust removal of the two is also similar. The historical dust removal efficiency value corresponding to the target matching value is obtained to obtain multiple historical dust removal efficiency values. In this way, dust removal experience of historical high-temperature gas with similar characteristics to the current high-temperature gas can be found as a reference to optimize the current dust removal, thereby ensuring the dust removal efficiency and the subsequent biomass energy conversion efficiency.

[0077] Optionally, in the aspect of adjusting the lower threshold according to the multiple historical dust removal efficiency values ​​to obtain the target lower threshold, the dust collector is specifically configured to:

[0078] Obtaining a sampling time of each of the plurality of historical dust removal efficiency values ​​to obtain a plurality of sampling times;

[0079] determining a disturbance parameter of a matching value corresponding to each of the plurality of historical dust removal efficiency values ​​to obtain a plurality of disturbance parameters;

[0080] performing a disturbance operation on corresponding historical dust removal efficiency values ​​among the multiple historical dust removal efficiency values ​​according to the multiple disturbance parameters to obtain multiple target historical dust removal efficiency values;

[0081] Performing a fitting operation based on the multiple target historical dust removal efficiency values ​​and the multiple sampling moments to obtain a fitting straight line;

[0082] Obtaining a target slope of the fitted straight line;

[0083] determining a second adjustment parameter corresponding to the target slope;

[0084] The lower threshold is adjusted upward according to the second adjustment parameter to obtain the target lower threshold.

[0085] In an embodiment of the present application, the sampling moment of each of the multiple historical dust removal efficiency values ​​can be obtained to obtain multiple sampling moments. The disturbance parameter of the matching value corresponding to each of the multiple historical dust removal efficiency values ​​can also be determined to obtain multiple disturbance parameters. That is, the mapping relationship between the preset matching value and the disturbance parameter can be pre-stored. Since there is still a certain difference between the historical high-temperature gas and the first high-temperature gas, the disturbance parameter can be used to disturb the dust removal efficiency value, thereby compensating for the difference between the historical high-temperature gas and the first high-temperature gas, so that the historical dust removal effect is more closely aligned with the first high-temperature gas. The larger the matching value, the larger the disturbance parameter. Conversely, the smaller the matching value, the smaller the disturbance parameter.

[0086] Next, a perturbation operation can be performed on the corresponding historical dust removal efficiency values ​​from the multiple historical dust removal efficiency values ​​based on multiple perturbation parameters to obtain multiple target historical dust removal efficiency values, i.e., target historical dust removal efficiency value = (1 + perturbation parameter) * historical dust removal efficiency value. A fitting operation is then performed based on the multiple target historical dust removal efficiency values ​​and multiple sampling moments to obtain a fitted straight line and the target slope of the fitted line. This slope, to a certain extent, reflects the equipment's decay trend. As equipment ages and its performance declines over time, the dust removal temperature control can be compensated based on the equipment's inherent properties, thereby ensuring dust removal effectiveness.

[0087] Furthermore, a mapping relationship between a preset slope and an adjustment parameter can be pre-stored, and the value range of the adjustment parameter is 0~0.1. Then, a second adjustment parameter corresponding to the target slope can be determined based on the mapping relationship. Then, the lower limit threshold can be adjusted upward according to the second adjustment parameter to obtain the target lower limit threshold, that is, the target lower limit threshold = (1+second adjustment parameter)*lower limit threshold. That is, on the one hand, the historical dust removal efficiency value can be disturbed based on the difference between the historical high-burning gas and the first high-burning gas, so that the disturbed historical dust removal efficiency value is more in line with the first high-temperature gas. On the other hand, fitting is performed based on the data after the disturbance, so that the fitting straight line is more in line with the actual situation of the equipment. The dust removal temperature control can be compensated based on the properties of the equipment itself, thereby ensuring the dust removal effect, which helps to ensure the combustion temperature effect of the subsequent second high-temperature gas, and then improve the utilization efficiency of biomass energy, so that the final dust removal temperature control range depth is in line with the equipment itself of the dust collector and improves the biomass energy conversion efficiency.

[0088] Optionally, in determining the first operating parameter corresponding to the first attribute information and the target operating mode, the circulating fluidized bed gasifier is specifically configured to:

[0089] determining a first reference operating parameter corresponding to the first attribute information;

[0090] determining a first feedback adjustment parameter corresponding to the target operating mode;

[0091] Feedback adjustment is performed on the first reference operating parameter according to the first feedback adjustment parameter to obtain the first operating parameter.

[0092] In an embodiment of the present application, a mapping relationship between preset biomass attribute information and working parameters can be pre-stored, and then, a first reference working parameter corresponding to the first attribute information can be determined based on the mapping relationship. A mapping relationship between a preset working mode and a feedback adjustment parameter can also be pre-stored, and then, a first feedback adjustment parameter corresponding to the target working mode can be determined based on the mapping relationship. The first reference working parameter is then feedback-adjusted according to the first feedback adjustment parameter to obtain the first working parameter, that is, the first working parameter = (1 + first feedback adjustment parameter) * first reference working parameter. On the one hand, the working parameters of the circulating fluidized bed gasifier can be dynamically determined based on the characteristics of the biomass and the needs of the gas boiler, so that the working parameters of the circulating fluidized bed gasifier are more in line with the characteristics of the biomass itself and the actual needs of the gas boiler. On the other hand, the first high-temperature fuel gas can be sent into the dust collector to further improve the purity of the combustible gas and thus improve the combustion efficiency.

[0093] In this embodiment, the transmission pipeline can be purged with nitrogen. Toxic and combustible gas detectors (detecting CO and H2, respectively) are installed at potential gas leak points along the transmission pipeline.

[0096] obtaining fourth attribute information of the second high-temperature fuel gas;

[0097] determining a reference transmission parameter corresponding to the fourth attribute information;

[0098] Obtaining a third operating parameter of the gas boiler;

[0105] The second high-temperature fuel gas is delivered to the gas boiler according to the second transmission parameter.

[0106] The second attribute information may include at least one of the following: gas composition, dust distribution density, dust particle size, gas density, gas mass ratio, etc., without limitation. The gas mass ratio of the second high-temperature fuel gas = gas mass in the second high-temperature fuel gas / (gas mass in the second high-temperature fuel gas + solid mass in the second high-temperature fuel gas).

[0107] The reference transmission parameters may include at least one of the following: transmission rate, transmission pressure, transmission time, etc., which are not limited here.

[0108] The third operating parameter may include at least one of the following: operating pressure, operating temperature, fuel consumption, exhaust temperature, etc., which are not limited here.

[0109] In a specific implementation, the fourth attribute information of the second high-temperature gas can be obtained, and a mapping relationship between preset attribute information and transmission parameters can be pre-stored. Then, based on the mapping relationship, a reference transmission parameter corresponding to the fourth attribute information can be determined. In this way, the corresponding transmission parameter can be adapted based on the characteristics of the high-temperature gas.

[0110] Then, a mapping relationship between preset working parameters and feedback adjustment parameters can be pre-stored, and a second feedback adjustment parameter corresponding to the third working parameter can be determined based on the mapping relationship. Then, the reference transmission parameter is feedback-adjusted according to the second feedback adjustment parameter to obtain the first transmission parameter, that is, the first transmission parameter = (1 + second feedback adjustment parameter) * reference transmission parameter. In this way, the third working parameter reflects the working efficiency of the gas boiler to a certain extent. Furthermore, the transmission parameter can be feedback-adjusted based on the working efficiency of the gas boiler to improve the working efficiency of the gas boiler.

[0112] Furthermore, the internal environmental parameters of the transportation pipeline and the external environmental parameters of the transportation pipeline can be obtained, wherein the influence of the internal environmental parameters plays a dominant role, and the influence of the external environmental parameters plays a secondary role. A mapping relationship between preset environmental parameters and adjustment parameters may also be pre-stored, and target adjustment parameters corresponding to internal environmental parameters may be determined based on the mapping relationship. A mapping relationship between preset environmental parameters and fine-tuning parameters may also be pre-stored, and target fine-tuning parameters corresponding to external environmental parameters may be determined based on the mapping relationship. Subsequently, the first transmission parameter may be adjusted based on the target adjustment parameter and the target fine-tuning parameter to obtain a second transmission parameter, i.e., the second transmission parameter = (1 + target adjustment parameter) * (1 + target fine-tuning parameter) * the first transmission parameter. The second high-temperature fuel gas is then delivered to the gas boiler based on the second transmission parameter. In this manner, the influence of the internal and external environments of the transmission channel may be further considered, wherein the influence of the internal environmental parameters plays a dominant role, while the influence of the external environmental parameters plays a secondary role. That is, the internal environmental parameters adjust the transmission parameters, while the external environmental parameters fine-tune the transmission parameters, so that the final transmission parameters are highly consistent with actual conditions. The final transmission parameters are adapted to the characteristics of the high-temperature fuel gas, can improve the operating efficiency of the gas boiler, and meet the actual environment. This helps ensure the subsequent combustion temperature effect of the second high-temperature fuel gas, thereby improving the utilization efficiency of biomass energy.
