Description

Technical Field

[0001] The present invention relates to the technical field of biomass energy utilization data analysis, and in particular to an intelligent evaluation method for agricultural waste resource utilization. Background Art

[0002] With the improvement of environmental awareness and the increase of energy demand, the market demand for biomass solidification fuel continues to expand. Straw solidification fuel produces almost no sulfur dioxide (SO2) and nitrogen oxides (NO x ), compared with traditional coal combustion, it can significantly reduce the emission of atmospheric pollutants. The existing technology produces finished products by crushing, mixing, drying and extruding the raw materials in sequence, which increases the storage time of the solidified fuel. However, the prepared biomass solidified fuel is affected by many factors and is prone to dust during the preparation process. The generation of dust not only increases the risk of air pollution, but may also cause wear on equipment and reduce production efficiency.

[0003] Chinese patent application number CN201510858737.1 discloses a novel biomass solidification fuel and its preparation method. The raw materials for the biomass solidification fuel are, by weight, 50-70 parts sawdust, 30-50 parts straw, 5-15 parts rice straw, and 30-50 parts peanut shells. The preparation method comprises: feeding the raw materials into a pulverizing device for pulverization, feeding the pulverized raw materials into a mixing device for thorough mixing, conveying the mixed raw materials via a conveyor line to a drying device for drying, and then conveying the dried raw materials via a conveyor line to an extrusion molding device for solidification and molding to produce a finished product. The advantages of this invention are: the finished biomass solidification fuel has dense, non-loose particles, can be stored for a long time, has a high combustion value, and produces little ash.

[0004] However, the prior art still has the following problems:

[0005] The prepared biomass solidified molded fuel is affected by many factors and is prone to generating dust during the preparation process. The generation of dust not only increases the risk of air pollution, but may also cause wear on equipment and reduce production efficiency. Summary of the Invention

[0006] To this end, the present invention provides an intelligent assessment method for agricultural waste resource utilization, which is used to overcome the problem that the biomass solidified molding fuel produced in the prior art is affected by multiple factors and is prone to generate dust during the preparation process. The generation of dust not only increases the risk of air pollution, but may also cause wear on equipment and reduce production efficiency.

[0007] To achieve the above objectives, the present invention provides an intelligent assessment method for agricultural waste resource utilization, including:

[0008] Step S1, washing the agricultural waste raw materials, feeding the washed agricultural waste raw materials into a crusher for crushing, drying the raw materials after crushing, collecting dust generated during the drying process, adding a biomass binder to the agricultural waste raw materials, mixing, and conveying the mixture to a molding device to produce a biomass solidified briquette fuel, and cooling the molded biomass solidified briquette fuel;

[0009] Step S2, obtaining the contour data of the cooled and formed biomass solidified molding fuel, and marking each biomass solidified molding fuel according to the matching degree between the contour data and the preset contour data;

[0010] Step S3: Count the number of each type of marked biomass solidification molding fuel, and evaluate whether the preparation of the current batch of biomass solidification molding fuel meets the standard based on the number of fuels. If it is preliminarily determined that the preparation of the current batch of biomass solidification molding fuel does not meet the standard,

[0011] Based on the concentration of dust generated during the drying process, a secondary judgment is made on whether the preparation of the current batch of biomass solidified briquette fuel meets the standards.

[0012] Alternatively, analyze the reasons why the preparation of the current batch of biomass solidified fuel does not meet the standards based on the percentage of the number of marked third-grade fuels;

[0013] Step S4, based on the analysis of the reason why the preparation of the current batch of biomass solidification molding fuel does not meet the standards, the corresponding parameters in the preparation process of the next batch of biomass solidification molding fuel are adjusted to the corresponding values, and the next batch of biomass solidification molding fuel is prepared according to the adjusted parameters. The parameters include: the rotation rate of the drying equipment, the crushing processing time, the stirring frequency of the mixer, and the amount of biomass adhesive added.

[0014] Furthermore, in step S2, each biomass solidified shaped fuel is marked according to the matching degree between the profile data and the preset profile data, including:

[0015] Counting the amount of data that is the same as the preset profile data to obtain the same amount of data,

[0016] The ratio of the same data amount to the total number of profile data is calculated to obtain the matching degree, and the biomass solidification molding fuel is marked based on the matching degree. The types of marked biomass solidification molding fuel include: primary fuel, primary fuel and tertiary fuel.

[0017] Furthermore, in step S3, whether the preparation of the current batch of biomass solidified fuel meets the standards is evaluated based on the proportion of the number of marked primary fuels.

[0018] When it is preliminarily determined that the preparation of the current batch of biomass solidification briquette fuel does not meet the standards, a secondary determination is made on whether the preparation of the current batch of biomass solidification briquette fuel meets the standards based on the concentration of dust generated during the drying process.

[0019] Alternatively, analyze the reasons why the preparation of the current batch of biomass solidified fuel does not meet the standards based on the percentage of the quantity marked as third-grade fuel.

[0020] Furthermore, in step S3, a secondary determination is made on whether the preparation of the current batch of biomass solidification briquette fuel meets the standards based on the concentration of dust generated during the drying process, including:

[0021] An optical sensor is used to detect the light scattering of dust particles generated during the drying process. The dust concentration is determined based on the scattering. The dust concentration data generated during the preparation of each batch of biomass solidification fuel in the historical records are obtained. Based on the dust concentration data, a time-dust concentration curve is drawn. The slope of each time node in the curve is determined, and the mean slope is calculated.

[0022] Based on the slope mean, analyze whether the preparation of the current batch of biomass solidified fuel meets the standards.

[0023] When determining that the preparation of the current batch of biomass solidification briquette fuel meets the standards, the input amount of agricultural waste raw materials in the single biomass solidification briquette fuel preparation process is adjusted based on the slope mean;

[0024] When it is determined that the preparation of the current batch of biomass solidification molding fuel does not meet the standards, it is determined that too much dust is generated during the preparation of the biomass solidification molding fuel.

[0025] Furthermore, under the condition that it is determined that too much dust is generated during the preparation of biomass solidification molding fuel, the rotation rate of the drying equipment during the drying process of agricultural waste raw materials is adjusted based on the slope mean, wherein the increase in the rotation rate is positively correlated with the slope mean.

[0026] Furthermore, in step S3, the reasons why the preparation of the current batch of biomass solidified molding fuel does not meet the standards are analyzed based on the proportion of the number of marked tertiary fuels, and the reasons include: insufficient crushing of agricultural waste raw materials, uneven mixing of agricultural waste raw materials, and insufficient biomass adhesive.

[0027] Furthermore, under the condition that the agricultural waste raw materials are determined to be insufficiently crushed, the difference between the proportion of the first preset fuel and the quantity proportion of the third-level fuel is calculated, and the crushing processing time in the preparation process of the next batch of biomass solidification molding fuel is adjusted based on the difference, wherein the increase in the crushing processing time is negatively correlated with the difference.

[0028] Furthermore, under the condition that the agricultural waste raw materials are determined to be unevenly mixed, the agricultural waste raw materials after crushing treatment in the preparation process of the next batch of biomass solidification molding fuel are stirred, and the variance of the matching degree of each three-level fuel in the biomass solidification molding fuel prepared in the current batch is calculated. The stirring frequency of the mixer is determined based on the variance, wherein the stirring frequency is positively correlated with the variance.

[0029] Furthermore, under the condition that the biomass adhesive is insufficient, the matching degree average of each three-level fuel in the current batch of biomass solidification molding fuel prepared is calculated, and the amount of biomass adhesive added during the preparation of the next batch of biomass solidification molding fuel is adjusted based on the matching degree average, wherein the increase in the amount of additive is negatively correlated with the matching degree average.

[0030] Furthermore, in step S4, the next batch of biomass solidified fuel prepared is marked, and the quantity of each type of fuel is counted.

[0031] When it is determined that the preparation of the biomass solidification molding fuel of the batch does not meet the standard based on the quantity of the primary fuel, the quantity ratio of the secondary fuel to the tertiary fuel is calculated, and the pressure of the molding equipment is adjusted based on the quantity ratio.

[0032] Among them, the reduction in pressure of the molding equipment is negatively correlated with the quantity ratio.

[0033] Compared with the prior art, the beneficial effect of the present invention lies in that, in the present invention, the fuel is marked according to the comparison between the profile of the prepared biomass solidification molding fuel and the preset profile data, and the prepared biomass solidification molding fuel is preliminarily evaluated to be qualified according to the quantity of each marked fuel type. When the profile data of the biomass solidification molding fuel deviates greatly from the preset profile data, considering that the preparation process is prone to generate dust, when the quantity ratio of the first-level fuel is between the first preset first-level fuel ratio and the second preset first-level fuel ratio, the prepared biomass solidification molding fuel is further evaluated to be qualified according to the concentration of dust generated during the drying process, thereby improving the control accuracy of the prepared biomass solidification molding fuel. When the quantity ratio of the first-level fuel is small, the prepared biomass solidification molding fuel is judged to be unqualified, and the reasons for the unqualified are analyzed, and then the parameters in the preparation process of the next batch of fuel are adjusted according to the analysis results, thereby improving the control accuracy of the preparation process of the next batch of fuel, improving the control accuracy of the quality of the next batch of fuel, reducing the amount of dust generated, and improving the safety of the preparation process.

[0034] Furthermore, the present invention takes into account that a large number of fine particles will be generated during the drying and crushing process of waste raw materials, and these particles are easy to form dust when the air flows. The present invention collects the dust generated during the drying process and detects the dust concentration. The integrity of the prepared biomass solidification molding fuel is analyzed according to the dust concentration, and then the quality of the prepared biomass solidification molding fuel is evaluated, and the safety of the biomass solidification molding fuel preparation process is evaluated. The present invention obtains the concentration of dust generated during the drying process when preparing each batch of biomass solidification molding fuel, and then analyzes the preparation status of the biomass solidification molding fuel according to the change of dust concentration. When the dust concentration gradually increases, timely warning is given, and the preparation parameters are adjusted in time, thereby further reducing the amount of dust generated and improving the safety of the preparation process.

[0035] Furthermore, the present invention obtains the dust concentration data generated during the preparation process of each batch of biomass solidification molding fuel, draws a curve based on the dust concentration data to determine the change in dust concentration, and analyzes whether the fuel preparation process is qualified based on the change in dust concentration. When the slope of the curve is large, considering that the drying time during the drying process of the waste raw materials is too long, resulting in too little moisture content in the raw materials, thereby increasing the amount of dust generated, by increasing the rotation speed of the rotary dryer, shortening the residence time of the raw materials in the dryer, thereby shortening the drying time, and then avoiding excessive moisture loss in the raw materials, thereby reducing the amount of dust generated.

[0045] See also Figure 1 As shown, it is a flow chart of the intelligent assessment method for agricultural waste resource utilization of the present invention.

[0046] The intelligent assessment method for agricultural waste resource utilization provided in this embodiment includes:

[0047] Step S1, washing the agricultural waste raw materials, feeding the washed agricultural waste raw materials into a crusher for crushing, drying the raw materials after crushing, collecting dust generated during the drying process, adding a biomass binder to the agricultural waste raw materials, mixing, and conveying the mixture to a molding device to produce a biomass solidified briquette fuel, and cooling the molded biomass solidified briquette fuel;

[0048] Step S2, obtaining the contour data of the cooled and formed biomass solidified molding fuel, and marking each biomass solidified molding fuel according to the matching degree between the contour data and the preset contour data;

[0049] Step S3: Count the number of each type of marked biomass solidification molding fuel, and evaluate whether the preparation of the current batch of biomass solidification molding fuel meets the standard based on the number of fuels. If it is preliminarily determined that the preparation of the current batch of biomass solidification molding fuel does not meet the standard,

[0050] Based on the concentration of dust generated during the drying process, a secondary judgment is made on whether the preparation of the current batch of biomass solidified briquette fuel meets the standards.

[0051] Alternatively, analyze the reasons why the preparation of the current batch of biomass solidified fuel does not meet the standards based on the percentage of the number of marked third-grade fuels;

[0052] Step S4, based on the analysis of the reason why the preparation of the current batch of biomass solidification molding fuel does not meet the standards, the corresponding parameters in the preparation process of the next batch of biomass solidification molding fuel are adjusted to the corresponding values, and the next batch of biomass solidification molding fuel is prepared according to the adjusted parameters. The parameters include: the rotation rate of the drying equipment, the crushing processing time, the stirring frequency of the mixer, and the amount of biomass adhesive added.

[0053] Specifically, in this embodiment, the specific components of the biomass adhesive are not limited, and corn starch or wood flour can be used.

[0054] Specifically, in this embodiment, the specific structure of the molding equipment is not limited. A screw extrusion molding machine or a piston briquetting molding machine can be used, which belongs to the existing technology and will not be described in detail here.

[0055] Specifically, in this embodiment, a rotary dryer is used to dry the agricultural waste raw materials after the crushing process. Under the action of the drive motor, reducer and transmission device, the rotating cylinder rotates around its own axis at a predetermined rotation rate, so that the material continuously rolls and moves in the cylinder, and is fully in contact with the hot air flow in the cylinder. A cyclone dust collector is connected to the air outlet of the rotary dryer, and the dust is separated by the principle of centrifugal force. The specific structure of the rotary dryer and the cyclone dust collector is not limited, and it belongs to the existing technology and will not be repeated here.

[0056] In the present invention, the fuel is marked according to the comparison between the profile of the prepared biomass solidification molding fuel and the preset profile data, and the qualification of the prepared biomass solidification molding fuel is preliminarily evaluated according to the quantity of each marked fuel. When the profile data of the biomass solidification molding fuel deviates greatly from the preset profile data, considering that the preparation process is prone to generate dust, when the quantity ratio of the first-level fuel is between the first preset first-level fuel ratio and the second preset first-level fuel ratio, the qualification of the prepared biomass solidification molding fuel is further evaluated according to the concentration of the dust generated during the drying process, thereby improving the control accuracy of the prepared biomass solidification molding fuel. When the quantity ratio of the first-level fuel is small, the prepared biomass solidification molding fuel is judged to be unqualified, and the reasons for the unqualified are analyzed. Then, according to the analysis results, the parameters in the preparation process of the next batch of fuel are adjusted, thereby improving the control accuracy of the preparation process of the next batch of fuel, improving the control accuracy of the quality of the next batch of fuel, reducing the amount of dust generated, and improving the safety of the preparation process.

[0057] See also Figure 2 As shown, it is a flow chart for determining the marking of each biomass solidified molding fuel.

[0058] Specifically, in step S2, each biomass solidified molding fuel is marked according to the matching degree between the profile data and the preset profile data, including:

[0059] Counting the amount of data that is the same as the preset profile data to obtain the same amount of data,

[0060] Calculate the ratio of the same data amount to the total number of contour data to obtain the matching degree.

[0061] If the matching degree is greater than or equal to the first preset matching degree, the biomass solidification molding fuel is marked as a first-level fuel;

[0062] If the matching degree is less than the first preset matching degree and greater than or equal to the second preset matching degree, the biomass solidification molding fuel is marked as a secondary fuel;

[0063] If the matching degree is less than the second preset matching degree, the biomass solidified molding fuel is marked as a third-level fuel.

[0064] Specifically, in this embodiment, the first preset matching degree is selected in the interval [0.88, 0.95], and the second preset matching degree is selected in the interval [0.79, 0.85].

[0065] See also Figure 3 As shown, it is a flow chart for evaluating whether the preparation of the current batch of biomass solidified molding fuel meets the standards.

[0066] Specifically, in step S3, whether the preparation of the current batch of biomass solidified fuel meets the standards is evaluated based on the proportion of the number of marked primary fuels, including:

[0067] If the proportion of the primary fuel is greater than or equal to the first preset proportion of the primary fuel, it is determined that the preparation of the current batch of biomass solidified molding fuel meets the standard;

[0068] If the proportion of the primary fuel is less than the first preset proportion of the primary fuel and greater than or equal to the second preset proportion of the primary fuel, it is preliminarily determined that the preparation of the current batch of biomass solidification molding fuel does not meet the standards, and a secondary determination is made on whether the preparation of the current batch of biomass solidification molding fuel meets the standards based on the concentration of dust generated during the drying process;

[0069] If the quantity ratio of the first-level fuel is less than the second preset first-level fuel ratio, it is determined that the preparation of the current batch of biomass solidification molding fuel does not meet the standards, and the reasons why the preparation of the current batch of biomass solidification molding fuel does not meet the standards are analyzed based on the quantity ratio of the fuel marked as the third-level fuel.

[0070] Specifically, in this embodiment, the first preset first-level fuel ratio is selected between the interval [0.85, 0.9], and the second preset first-level fuel ratio is selected between the interval [0.75, 0.8].

[0071] See also Figure 4 As shown, it is a flow chart for secondary determination of whether the preparation of the current batch of biomass solidified molding fuel meets the standards.

[0072] Specifically, in step S3, a secondary determination is made on whether the preparation of the current batch of biomass solidified briquette fuel meets the standards based on the concentration of dust generated during the drying process, including:

[0073] An optical sensor is used to detect the light scattering of dust particles generated during the drying process. The dust concentration is determined based on the scattering. The dust concentration data generated during the preparation of each batch of biomass solidification fuel in the historical records are obtained. Based on the dust concentration data, a time-dust concentration curve is drawn. The slope of each time node in the curve is determined, and the mean slope is calculated.

[0074] If the slope mean is less than or equal to the preset slope mean standard threshold, it is determined that the preparation of the current batch of biomass solidification molding fuel meets the standard, and the input amount of agricultural waste raw materials in the single biomass solidification molding fuel preparation process is adjusted based on the slope mean;

[0075] If the slope mean is greater than the preset slope mean standard threshold, it is determined that the preparation of the current batch of biomass solidification molding fuel does not meet the standard, and it is determined that too much dust is generated during the preparation of the biomass solidification molding fuel.

[0076] Specifically, in this embodiment, the preset slope mean standard threshold is obtained in advance, and the concentration data of dust generated during the drying process during the preparation of biomass solidification molding fuel under several qualified conditions is obtained. The time-concentration curve is drawn, the slope of each time node in the image is solved, and the slope mean is solved. The preset slope mean standard threshold is 0.95 to 1.2 times the slope mean.

[0077] The present invention takes into account that a large number of fine particles will be generated during the drying and crushing process of waste raw materials. These particles are easy to form dust when the air flows. The present invention collects the dust generated during the drying process and detects the dust concentration. The integrity of the prepared biomass solidification molding fuel is analyzed according to the dust concentration, and then the quality of the prepared biomass solidification molding fuel is evaluated, and the safety of the biomass solidification molding fuel preparation process is evaluated. The present invention obtains the concentration of dust generated during the drying process when preparing each batch of biomass solidification molding fuel, and then analyzes the preparation status of the biomass solidification molding fuel according to the change of dust concentration. When the dust concentration gradually increases, timely warning is issued, and the preparation parameters are timely adjusted, thereby further reducing the amount of dust generated and improving the safety of the preparation process.

[0078] Specifically, under the condition that it is determined that too much dust is generated during the preparation of biomass solidification molding fuel, the rotation rate of the drying equipment during the drying process of agricultural waste raw materials is adjusted based on the slope mean, wherein the increase in the rotation rate is positively correlated with the slope mean.

[0079] In the present invention, the dust concentration data generated during the preparation of each batch of biomass solidification molding fuel is obtained, a curve is drawn according to the dust concentration data to determine the change in dust concentration, and whether the fuel preparation process is qualified is analyzed according to the change in dust concentration. When the slope of the curve is large, it is considered that the drying time during the drying process of the waste raw material is too long, resulting in too little moisture content in the raw material, thereby increasing the amount of dust generated. By increasing the rotation speed of the rotary dryer, the residence time of the raw material in the dryer is shortened, thereby shortening the drying time, and then avoiding excessive moisture loss in the raw material, thereby reducing the amount of dust generated.

[0080] In this embodiment, optionally,

[0081] Compare the slope mean with the first preset slope mean standard threshold and the second preset slope mean standard threshold,

[0082] If the slope average is less than or equal to a first preset slope average standard threshold, increasing a first rotation rate, the first rotation rate being 0.1 times the initial rotation rate;

[0083] If the slope average is greater than the first preset slope average standard threshold and less than or equal to the second preset slope average standard threshold, increasing the second rotation rate, the second rotation rate being 0.15 times the initial rotation rate;

[0084] If the slope average is greater than the second preset slope average standard threshold, increasing a third rotation rate, the third rotation rate being 0.2 times the initial rotation rate;

[0085] The first preset slope mean standard threshold is 1.15 times the preset slope mean standard threshold, and the second preset slope mean standard threshold is 1.2 times the preset slope mean standard threshold.

[0086] Specifically, in step S3, the reasons why the preparation of the current batch of biomass solidified fuel does not meet the standards are analyzed based on the proportion of the number of marked tertiary fuels, including:

[0087] If the proportion of the tertiary fuel is less than or equal to the first preset tertiary fuel proportion, it is determined that the reason why the preparation of the current batch of biomass solidified molding fuel does not meet the standard is that the agricultural waste raw materials are not sufficiently crushed;

[0088] If the proportion of the tertiary fuel is greater than the first preset tertiary fuel proportion and less than or equal to the second preset tertiary fuel proportion, it is determined that the reason why the preparation of the current batch of biomass solidified molding fuel does not meet the standards is that the agricultural waste raw materials are not mixed uniformly;

[0089] If the proportion of the tertiary fuel is greater than the second preset tertiary fuel proportion, it is determined that the reason why the preparation of the current batch of biomass solidified molding fuel does not meet the standards is that the biomass adhesive is insufficient.

[0090] Specifically, in this embodiment, the first preset three-level fuel ratio is selected between the interval [0.05, 0.1], and the second preset three-level fuel ratio is selected between the interval [0.15, 0.18].

[0091] Specifically, under the condition that it is determined that the agricultural waste raw materials are not sufficiently crushed, the difference between the proportion of the first preset fuel and the quantity proportion of the third-level fuel is calculated, and the crushing processing time in the preparation process of the next batch of biomass solidification molding fuel is adjusted based on the difference, wherein the increase in the crushing processing time is negatively correlated with the difference.

[0092] In this embodiment, optionally,

[0093] Compare the difference with the first preset difference and the second preset difference,

[0094] If the difference is less than or equal to the first preset difference, the first crushing processing time is increased, and the first crushing processing time is 0.1 times the initial crushing processing time;

[0095] If the difference is greater than the first preset difference and less than or equal to the second preset difference, the second crushing processing time is increased, and the second crushing processing time is 0.2 times the initial crushing processing time;

[0096] If the difference is greater than the second preset difference, the third crushing processing time is increased, and the third crushing processing time is 0.25 times the initial crushing processing time;

[0097] The first preset difference is 0.2 times the first preset fuel ratio, and the second preset difference is 0.3 times the first preset fuel ratio.

[0098] Specifically, under the condition that the agricultural waste raw materials are determined to be unevenly mixed, the agricultural waste raw materials that have been crushed in the preparation process of the next batch of biomass solidification molding fuel are stirred, and the variance of the matching degree of each three-level fuel in the current batch of biomass solidification molding fuel is calculated. The stirring frequency of the mixer is determined based on the variance, wherein the stirring frequency is positively correlated with the variance.

[0099] In this embodiment, optionally,

[0100] Compare the variance with the first preset variance and the second preset variance,

[0101] If the variance is less than or equal to the first preset variance, determining that the stirring frequency of the stirrer is the first stirring frequency;

[0102] If the variance is greater than the first preset variance and less than or equal to the second preset variance, determining that the stirring frequency of the stirrer is the second stirring frequency;

[0103] If the variance is greater than the second preset variance, determining that the stirring frequency of the stirrer is a third stirring frequency;

[0104] Among them, the first preset variance and the second preset variance are obtained by preset measurements. Data of several qualified batches of biomass solidification molding fuel are obtained, and the variance of the matching degree of the tertiary fuel produced by a single batch is calculated respectively. The mean variance of each batch is solved. The first preset variance is 1.05 to 1.1 times the mean variance, and the second preset variance is 0.15 to 1.2 times the mean variance.

[0105] Specifically, under the condition that it is determined that the biomass adhesive is insufficient, the matching degree average of each three-level fuel in the current batch of biomass solidification molding fuel prepared is calculated, and the amount of biomass adhesive added during the preparation of the next batch of biomass solidification molding fuel is adjusted based on the matching degree average, wherein the increase in the amount of additive is negatively correlated with the matching degree average.

[0106] In this embodiment, optionally,

[0107] Compare the matching degree mean with the first preset matching degree mean and the second preset matching degree mean,

[0108] If the matching degree mean is less than or equal to the first preset matching degree mean, then increase the first dose, which is 0.25 times the initial additive dosage;

[0109] If the matching degree mean is greater than the first preset matching degree mean and less than or equal to the second preset matching degree mean, then increase the second dose, which is 0.2 times the initial additive dosage;

[0110] If the matching degree mean is greater than the second preset matching degree mean, a third dose is added, and the third dose is 0.1 times the initial additive dosage;

[0111] Among them, the first preset matching degree mean and the second preset matching degree mean are obtained in advance, and data of several qualified batches of biomass solidification molding fuel are obtained to solve the matching degree mean of the three-level fuel. The first preset matching degree mean is 0.75 to 0.8 times the matching degree mean, and the second preset matching degree mean is 0.85 to 0.9 times the matching degree mean.

[0112] Specifically, in step S4, the next batch of biomass solidified fuels to be prepared are marked, and the quantity of each type of fuel is counted.

[0113] If the re-counted proportion of the first-level fuel is greater than or equal to the first preset proportion of the first-level fuel, it is determined that the preparation of the biomass solidification molding fuel of this batch meets the standard;

[0114] If the re-counted proportion of the primary fuel is less than the first preset proportion of the primary fuel, it is determined that the preparation of the biomass solidification molding fuel of this batch does not meet the standard, and the ratio of the secondary fuel to the tertiary fuel is calculated, and the pressure of the molding equipment is adjusted based on the ratio.

[0115] Among them, the reduction in pressure of the molding equipment is negatively correlated with the quantity ratio.

[0116] In this embodiment, optionally,
