[0056] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0057] According to an embodiment of the present application, a sludge coupling incineration proportion calculation method embodiment is provided. It should be noted that the steps shown in the flow chart of the drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flow chart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.

[0058] In the present embodiment, a sludge coupling incineration proportion calculation method is provided, which can be used in the occasion of coal-fired power plant cooperating with sludge blending combustion, such as shown in the figure. Figure 1 The sludge coupling incineration proportion calculation method includes the following steps:

[0059] Step S1: Obtain attribute data of fuel and sludge, parameter data of coal mill and chlorine ion limit value in the sludge blending combustion process. Specifically, the chlorine ion limit value in the sludge blending combustion process is obtained to ensure that the pollutant emission in the blending combustion process does not exceed the corresponding emission standard.

[0060] Step S2: Calculate the pollution blending proportion based on the chlorine ion limit value of the attribute data. Specifically, the pollution blending proportion is the proportion of sludge that can be occupied under the premise of not exceeding the emission standard. This process considers the content of chlorine ions in fuel and sludge and calculates the critical proportion to avoid the problem of excessive chlorine ions in ash and slag causing pollution exceeding the standard and excessive chlorine ions in flue gas causing heat surface coking during the combustion process.

[0061] Step S3: Calculate the air-temperature co-firing ratio based on attribute and parameter data. Specifically, by calculating the air-temperature co-firing ratio, the problem of excessively low pulverizer outlet air temperature, i.e., insufficient drying output, leading to moisture condensation, further causing coal blockage, and affecting the safe operation of the unit can be avoided.

[0062] Step S4: The minimum value between the pollutant co-firing ratio and the air-temperature co-firing ratio is taken as the sludge incineration ratio. Specifically, when co-firing sludge, the chlorine (Cl) content of the sludge and coal mixed fuel... 总 Cannot exceed Cl max , and Cl 总 =Cl 污泥 ×α+Cl 燃料 ×(1-α), from which α can be calculated. max1 Meanwhile, the outlet air temperature of the coal mill must not be lower than the condensation temperature of water, i.e., T. 出口风温 ≥T min Therefore, the maximum blending ratio α can be obtained. max2 Compare α max1 α max2 The minimum of the two values ​​is taken as the sludge incineration ratio α. max By precisely controlling the sludge incineration ratio by taking the minimum value, the unit can avoid coking on the heating surface and excessively low coal mill outlet air temperature, which can lead to condensation and coal blockage, while meeting emission standards, thus ensuring safe operation of the unit.

[0063] Through steps S1 to S4 above, the sludge co-incineration ratio calculation method provided in this embodiment of the invention can accurately control the sludge co-incineration ratio by comprehensively considering chloride ion emissions and coal mill outlet air temperature. This avoids excessive chloride ions in ash and slag caused by improper mixing ratio, coking of heated surfaces due to excessive chloride ions in flue gas, and condensation and coal blockage caused by excessively low coal mill outlet air temperature. This ensures the safe operation of the unit while meeting emission standards.

[0064] Specifically, in one embodiment, the chloride ion limit value obtained in step S1 above during the sludge co-firing process is as follows: Figure 2 As shown, the specific steps include the following:

[0065] Step S11: Conduct sludge co-firing tests under different preset unit conditions. Specifically, since the migration patterns of chloride ions in sludge and coal in coal-fired boilers are not yet clear when sludge is coupled with coal for power generation, it is difficult to determine the chloride ion distribution through theoretical calculations. Experiments are needed to determine the distribution patterns of chloride ions in flue gas, ash, and slag under typical combustion conditions. Co-firing tests can be conducted under high, medium, and low unit loads, with typical grinding conditions for each load. Data can be obtained during and after the tests. Reliable experimental data can be obtained through combustion tests, thereby improving the accuracy of the calculated ratio.

[0066] Step S12: Acquire the first chlorine content data in the flue gas in real time during the test.

[0067] Step S13: Test the combustion sample after the test to obtain the secondary chlorine content data in the ash and the tertiary chlorine content data in the slag.

[0068] Step S14: Compare the first chlorine content data, the second chlorine content data, and the third chlorine content data with their respective preset standard values ​​to obtain the chloride ion limit values.

[0069] Specifically, by accurately calculating the chloride ion limit, it is possible to avoid excessive chloride ions in ash and slag caused by improper blending ratios, as well as coking on the heating surface caused by excessive chloride ions in flue gas. This ensures that the pollution emissions from combustion in the correct proportions meet the standards during subsequent calculations, while also guaranteeing the safety of unit operation.

[0070] Specifically, in one embodiment, step S14 described above is as follows: Figure 3 As shown, the specific steps include the following:

[0071] Step S141: Compare the first, second, and third chlorine content data with their respective preset standard values ​​to determine whether they exceed the standard. Specifically, the first chlorine content data is the chloride ion content data in the flue gas, and the second chlorine content data includes the chloride ion content data in the ash and the chloride ion content data in the slag.

[0072] Step S142: If any exceedances are found, the first, second, and third chlorine content data are recalculated according to the proportion of exceedance to obtain the first, second, and third chlorine content data that meet the standards. Specifically, since excessive chlorine content affects pollution emissions, unit operation, and sample recycling, the chloride ion content data in flue gas, ash, and slag are compared with their respective preset standard values. If the values ​​exceed the standard values, the data are adjusted to ensure that the final calculated limits are within the standard range.

[0073] Step S143: If there is no exceedance, then the first chlorine content data, the second chlorine content data, and the third chlorine content data are the first chlorine content data, the second chlorine content data, and the third chlorine content data that meet the standards.

[0074] Step S144: The minimum value among the first chlorine content data, the second chlorine content data, and the third chlorine content data that meet the standard shall be used as the chloride ion limit.

[0075] Specifically, for example, by conducting co-firing tests, the Cl under typical combustion conditions can be determined. 总 Cl 烟气 Cl灰 , Cl 渣 , Cl 总 , Cl 烟气 , Cl 灰 , Cl 渣 The flue gas, ash, and slag all have requirements for the content of chloride ions, and too high a content of chlorine has an impact on the operation of the unit and the recycling of the sample. The data are compared with respective preset standard values, and definitions are made: a = Cl 烟气 / Cl 烟气允许 , b = Cl 灰 / Cl 灰允许 , and c = Cl 渣 / Cl 渣允许 If a, b, and c are all less than 1, it indicates that Cl 总 is not over the standard at this time, and if there is a value greater than 1 among a, b, and c, it indicates that Cl 总 has already exceeded the standard at this time, and the corresponding Cl 总max needs to be obtained by proportional conversion according to the coefficient. The maximum value of the chlorine in the fuel corresponding to the chlorine not over the standard in the flue gas is denoted as Cl 烟气max , the maximum value of the chlorine in the fuel corresponding to the chlorine not over the standard in the ash is denoted as Cl 灰max , and the maximum value of the chlorine in the fuel corresponding to the chlorine not over the standard in the slag is denoted as Cl 渣max . Further, Cl 烟气max , Cl 灰max , and Cl 渣max are compared, and the minimum value among the three is taken as Cl max .

[0076] By calculating the chloride ion limit value, it can be ensured that the pollution emission in the combustion process meets the standard and the safety of the operation of the unit is guaranteed in the subsequent calculation of the proportion.

[0077] Specifically, in an embodiment, the step S2 described above specifically includes the following steps as shown in FIG. 2. Figure 4

[0078] Step S21: Extracting the chloride ion content of sludge and the chloride ion content of fuel from the attribute data. Specifically, the chloride ion content of sludge and the chloride ion content of fuel are obtained by detecting the samples of sludge and fuel, and have high accuracy.

[0079] Step S22: Establishing a pollution function of total chloride ion output and pollution blending ratio based on the chloride ion content of sludge and the chloride ion content of fuel. Specifically, Cl 总 = Cl 污泥 × a + Cl 燃料 × (1-a), wherein Cl 总 is the total chloride ion output, Cl 污泥 is the chloride ion content of sludge, and Cl 燃料 is the chloride ion content of fuel.For fuel chlorine ion content, a is the doping ratio.

[0080] Step S23: Solve the pollution function according to the chlorine ion limit to obtain the pollution blending ratio.

[0081] Specifically, to ensure that the total output of chlorine ions is less than the chlorine ion limit, Cl 总 <Cl max , solve to obtain the pollution blending ratio a max1 . Since too high chlorine ions in ash and slag will cause pollution to exceed the standard, and too high chlorine ions in flue gas will cause heat surface coking, the pollution blending ratio calculated in this process can effectively solve this problem on the premise of ensuring calculation accuracy.

[0082] Specifically, in an embodiment, the above step S3, as shown in Figure 5 , specifically includes the following steps:

[0083] Step S31: Obtain environmental temperature, fuel moisture data and preset mixed fuel input data, and extract sludge moisture data from attribute data and extract air volume data and inlet air temperature data from parameter data. Specifically,

[0084] Step S32: Based on the environmental temperature, fuel moisture data, preset mixed fuel input data, sludge moisture data, air volume data and inlet air temperature data, establish a dew water temperature and air temperature blending ratio air temperature function equation.

[0085] Step S33: Based on the preset dew water temperature, solve the air temperature function equation to obtain the air temperature blending ratio.

[0086] Specifically, the outlet air temperature of the coal mill is related to a plurality of parameters, and there is a function relationship between the parameters as follows: Toutlet air temperature=f(Q 风量 , Q 总 , T 入口风温 , T 环境 , M 燃料 , M 污泥 , a), wherein the environmental temperature T 环境 , the moisture content M 燃料 in the coal, the moisture content M 污泥 in the sludge are measured values, and the air volume Q 风量 of the coal mill, the inlet air temperature T 入口风温 of the coal mill are parameter data of the coal mill. According to the function relationship, when Q 风量 , Q 总 , T 入口风温 , T 环境 , M 燃料 , M 污泥When the coal mill outlet air temperature is constant, it is only related to the blending ratio α, and the coal mill outlet air temperature is required to be not lower than the dew point of water, i.e., Toutlet air temperature≥Tmin, so that the maximum blending ratio α can be obtained max2 This process is to ensure the coal mill outlet air temperature and prevent water dewing to cause coal blocking and ensure safe operation of the unit.

[0087] Specifically, in an embodiment, as shown in Figure 6 The above method specifically further includes the following steps:

[0088] Step S41: Real-time temperature data of the environment and real-time mixed fuel input data are obtained.

[0089] Step S42: A dewing water temperature and air temperature blending ratio air temperature dynamic equation is established based on the real-time temperature data, fuel moisture data, real-time mixed fuel input data, sludge moisture data, air volume data and inlet air temperature data.

[0090] Step S43: The real-time air temperature blending ratio is obtained by solving the dewing water temperature based on the air temperature dynamic equation.

[0091] Specifically, by monitoring the environmental temperature data and the mixed fuel input in real time, the air temperature blending ratio can be dynamically monitored, and the operator can be displayed in a dynamic display manner as a real-time reference.

[0092] Specifically, in an embodiment, as shown in Figure 7 The above method specifically further includes the following steps:

[0093] Step S51: The real-time air temperature blending ratio is compared with the sludge incineration ratio.

[0094] Step S52: When the real-time air temperature blending ratio exceeds the sludge incineration ratio, an alarm is given.

[0095] Specifically, by comparing the real-time monitoring and calculation of the air temperature blending ratio with the sludge incineration ratio, the operator is alarmed when the sludge incineration ratio is exceeded, so that the operator can timely adjust the sludge feeding ratio to ensure safe operation of the unit.
