[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] The denitrification control method provided in the embodiment of the present application is applied to a denitrification control device, wherein an in-situ sampling device and an ammonia strong oxidation channel are installed at the outlet of the denitrification control device, wherein the in-situ sampling device is used to detect the nitrogen oxide concentration at the outlet of the denitrification control device, and the ammonia strong oxidation channel includes an oxidant and a NOx detector, wherein the oxidant is used to convert ammonia into nitrogen oxides, and the NOx detector is used to detect the nitrogen oxide concentration.

[0028] Specifically, see Figure 1 , Figure 1 Schematic diagram of the flue cross section of the denitrification control device provided in the embodiment of the present application. Figure 1 As shown, six in-situ sampling devices 10 and six ammonia strong oxidation channels 20 are provided on the flue of the denitrification control device, and the in-situ sampling devices 10 and the ammonia strong oxidation channels 20 are arranged at intervals. It should be understood that in other embodiments, other arrangements can also be used to install the in-situ sampling devices 10 and the ammonia strong oxidation channels 20 at the outlet of the denitrification control device, which is not specifically limited here.

[0029] Please attend Figure 2 , Figure 2 This is a flow chart of the denitrification control method provided in the embodiment of the present application, such as Figure 2 As shown, this embodiment provides a denitration control method, which is applied to a denitration control device. The method includes the following steps:

[0030] S101, obtaining a first nitrogen oxide concentration and a second nitrogen oxide concentration.

[0031] The above-mentioned first nitrogen oxide concentration is the nitrogen oxide concentration discharged from the outlet of the denitrification control device. Optionally, the nitrogen oxide concentration monitored in real time by the above-mentioned in-situ sampling device, or the nitrogen oxide concentration detected within a preset time period, can be determined as the first nitrogen oxide concentration.

[0032] The above-mentioned second nitrogen oxide concentration is determined based on the ammonia concentration discharged at the outlet of the denitrification control device. Optionally, the ammonia discharged from the denitrification control device can be treated accordingly through the above-mentioned ammonia strong oxidation channel, and the nitrogen oxides detected in real time by the NOx detector in the ammonia strong oxidation channel, or the nitrogen oxide concentration detected within a preset time period, is determined as the second nitrogen oxide concentration. For specific implementation methods, please refer to subsequent examples.

[0033] S102 : When the difference between the second nitrogen oxide concentration and the first nitrogen oxide concentration is greater than a preset value, determine a total ammonia requirement according to the second nitrogen oxide concentration.

[0034] As mentioned above, the second nitrogen oxide concentration is determined based on the ammonia discharged from the denitrification control device. It should be noted that if ammonia escape occurs in the denitrification control device, the denitrification control device will discharge excess ammonia. In this case, the second nitrogen oxide concentration obtained based on the ammonia discharged from the denitrification control device is greater than the first nitrogen oxide concentration.

[0035] In this step, by setting a preset value, when the difference between the second nitrogen oxide concentration and the first nitrogen oxide concentration is greater than the preset value, it indicates that there is excess ammonia in the gas discharged from the denitrification control device, and it is determined that the denitrification control device has caused ammonia slip. In this case, the total required ammonia amount is determined based on the second nitrogen oxide concentration. For the specific technical solution on how to determine the total required ammonia amount, please refer to the subsequent embodiments.

[0036] It should be understood that when the difference between the second nitrogen oxide concentration and the first nitrogen oxide concentration is less than or equal to a preset value, it indicates that there is no ammonia slip in the denitration control device. The preset value is a value set by the user.

[0037] S103: Generate a valve scheduling result based on the total ammonia demand.

[0038] S104: Dispatching the valve to perform ammonia injection according to the valve dispatching result.

[0039] In this step, the opening size of the ammonia injection valve is determined according to the total ammonia demand, so as to schedule the valve to perform ammonia injection.

[0040] For example: when the total ammonia demand in the denitrification control device is large, the ammonia injection valve in the denitrification control device is adjusted to a larger opening so that more ammonia can react with the flue gas; when the total ammonia demand in the denitrification control device is small, the ammonia injection valve in the denitrification control device is adjusted to a smaller opening so that less ammonia can react with the flue gas.

[0041] It should be noted that the amount of ammonia injected by the ammonia injection valve in the denitrification control device is related not only to the opening degree of the ammonia injection valve in the denitrification control device, but also to the opening time of the ammonia injection valve in the denitrification control device, which is not limited in this embodiment.

[0042] To understand the overall technical solution, please refer to Figure 3 ,like Figure 3 As shown, the overall ammonia injection workflow of the denitrification control device is as follows: obtaining a first nitrogen oxide concentration detected by the in-situ sampling device and a second nitrogen oxide concentration detected by the NOx detector in the ammonia strong oxidation channel; judging whether there is ammonia slip in the denitrification control device based on the relationship between the first nitrogen oxide concentration and the second nitrogen oxide concentration; if there is ammonia slip, determining the total ammonia requirement according to the second nitrogen oxide concentration, and adjusting the opening of the ammonia injection valve according to the total ammonia requirement; if there is no ammonia slip, not adjusting the opening of the ammonia injection valve.

[0043] In an embodiment of the present application, a first nitrogen oxide concentration is determined based on the nitrogen oxide concentration discharged from the outlet of the denitration control device, and a second nitrogen oxide concentration is determined based on the ammonia concentration discharged from the outlet of the denitration control device. If the difference between the second nitrogen oxide concentration and the first nitrogen oxide concentration is greater than a preset value, indicating that ammonia slip has occurred during the operation of the denitration control device, a valve scheduling result is generated based on the second nitrogen oxide concentration, and the valve is scheduled to perform ammonia injection according to the valve scheduling result. By scheduling the valve to perform ammonia injection in this manner, precise ammonia injection is achieved, thereby eliminating ammonia slip during the operation of the denitration control device and improving the denitration control effect.

[0044] Optionally, obtaining the second nitrogen oxide concentration includes:

[0045] oxidizing the ammonia discharged from the outlet of the denitration control device to obtain nitrogen oxides converted from the ammonia;

[0046] The concentration of the nitrogen oxides converted from the ammonia gas is detected to obtain the second nitrogen oxide concentration.

[0047] As mentioned above, an ammonia strong oxidation channel is installed at the outlet of the denitrification control device, and the ammonia strong oxidation channel includes an oxidant and a NOx detector.

[0048] Optionally, the ammonia discharged from the outlet of the denitration control device is oxidized by the above-mentioned oxidant to obtain nitrogen oxides converted from ammonia. Specifically, the nitrogen oxides can be obtained by oxidizing ammonia according to the following chemical formula.

[0049] 4NH3+5O2=4NO+6H2O

[0050] In this embodiment, the NOx detector detects the concentration of nitrogen oxides converted from ammonia to obtain a second nitrogen oxide concentration. It should be noted that if ammonia slip occurs in the denitration control device, i.e., if excessive ammonia is present in the gas discharged from the denitration control device, the second nitrogen oxide concentration detected by the NOx detector will be greater than the first nitrogen oxide concentration detected by the in-situ sampling device.

[0051] Optionally, after the second nitrogen oxide concentration is determined, the ammonia content in the exhaust gas may be calculated according to the above chemical formula.

[0052] In this embodiment, an ammonia strong oxidation channel is installed at the outlet of the denitrification control device to convert the exhausted ammonia into nitrogen oxides, and the second nitrogen oxide concentration of the nitrogen oxides after the ammonia conversion is detected, thereby accurately judging whether there is ammonia escape in the denitrification control device based on the second nitrogen oxide concentration.

[0053] Optionally, determining the total ammonia requirement according to the second nitrogen oxide concentration includes:

[0054] The ammonia slip correction amount is calculated by a proportional-integral-derivative controller;

[0055] determining a dynamic actual ammonia supply amount according to the ammonia slip correction amount and the actual ammonia supply amount;

[0056] The total ammonia requirement is determined based on the dynamic actual ammonia supply and the preset ammonia requirement.

[0057] In this embodiment, the actual ammonia slip concentration may be input into a Proportional Integration Differentiation (PID) controller, and the ammonia slip correction amount may be calculated by the PID controller.

[0058] Specifically, the ammonia slip correction amount can be determined by the following formula 1:

[0059] Formula 1:

[0060]

[0061] Where, γ(t) = EE r , E represents the set value of ammonia escape concentration, E r It represents the average value of actual ammonia escape concentration determined based on the ammonia concentration discharged from the outlet of the denitrification control device. and They represent the proportional (P), integral (I) and differential (D) gain coefficients used to calculate and correct ammonia slip, t represents the current time, τ represents the integral, and δA represents the ammonia slip correction amount.

[0062] After determining the ammonia slip correction amount, the dynamic actual ammonia supply amount is determined based on the ammonia slip correction amount and the actual ammonia supply amount; then, the total ammonia demand is determined based on the dynamic actual ammonia supply amount and the preset ammonia demand amount. For specific implementation methods, please refer to the subsequent embodiments.

[0063] In this embodiment, the ammonia slip correction amount is calculated by a proportional-integral-differential controller, and the total ammonia requirement is accurately calculated based on the ammonia slip correction amount, the actual ammonia supply amount and the preset ammonia requirement; then, in subsequent steps, the opening of the ammonia injection valve is determined based on the total ammonia requirement to achieve precise ammonia injection, thereby improving the denitrification effect.

[0064] Optionally, determining the dynamic actual ammonia supply amount according to the ammonia slip correction amount and the actual ammonia supply amount includes:

[0065] The ammonia slip correction amount is added to the actual ammonia supply amount to obtain the dynamic actual ammonia supply amount.

[0066] In this embodiment, the actual ammonia supply amount can be determined by the following formula 2.

[0067] Formula 2:

[0068] A c =δA+A r

[0069] Among them, A c Indicates the actual dynamic ammonia supply, δA indicates the ammonia slip correction, A r Indicates the actual amount of ammonia supplied.

[0070] Optionally, determining the total ammonia requirement according to the dynamic actual ammonia supply and the preset ammonia requirement includes:

[0071] Subtracting the preset ammonia demand from the dynamic actual ammonia supply to obtain a target parameter;

[0072] The target parameter is calculated by the proportional-integral-derivative controller to determine the total ammonia requirement.

[0073] In this embodiment, the total ammonia requirement can be determined by the following formula 3:

[0074] Formula 3:

[0075]

[0076] α(t)=AA c

[0077] Where Z represents the total ammonia required, and They represent the proportional (P), integral (I) and differential (D) gain coefficients used to calculate the total ammonia demand, t represents the current time, τ represents the integral, α(t) represents the target parameter, A represents the preset ammonia demand, and A c Indicates the dynamic actual ammonia supply.

[0078] To understand the calculation process of total ammonia demand, please refer to Figure 4 , Figure 4 The E shown represents the ammonia slip concentration setting value, E r A represents the average actual ammonia escape concentration determined based on the ammonia concentration discharged from the outlet of the denitrification control device. r Indicates the actual ammonia supply, δA indicates the ammonia slip correction, A indicates the preset ammonia requirement, A c Indicates the dynamic actual ammonia supply.
