Description
Technical Field
The invention belongs to the technical field of nitrogen oxide emission control, and particularly relates to a nitrogen oxide emission accurate control method and device based on environmental protection cost.
Background
With the development of environmental protection concept, nitrogen oxides, as one of the influencing factors of environmental pollution, are more and more strictly limited in emission concentration and emission amount, which undoubtedly increases additional environmental protection cost for production enterprises. Due to the effects of policy factors, emission control of nitrogen oxides presents environmental costs in stages, such as: the limit value of the emission concentration of the kiln tail flue gas NOx (nitrogen oxide, the same below) in the early Chongqing area is 350mg/m3The special emission limit in the emission Standard of pollutants for Industrial Cement industry (GB4915-2013) is executed from 7 months in 2019, and the emission concentration limit of the kiln tail flue gas NOx is 320mg/m3. If the monthly average emission concentration is lower than 70% of the limit value, the environmental protection tax is collected according to 75% of the charge; and if the monthly emission concentration is lower than 50 percent of the limit value, the environmental protection tax is collected according to 50 percent of the required collection. It can be seen that the environmental tax cost is distributed in a ladder shape, but for enterprises, the reduction of the emission concentration of the nitrogen oxides can improve the consumption cost of the ammonia water for emission reduction control.
Therefore, on one hand, the environmental protection tax needs to be in a more favorable tax reduction gear as much as possible, and on the other hand, the consumption of ammonia water needs to be controlled as little as possible, and the factors are not considered in the prior art.

Detailed Description
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
The embodiment of the invention adopts the following technical scheme:
the first embodiment is as follows:
referring to fig. 1, the present embodiment provides a method for accurately controlling nitrogen oxide emission based on environmental protection cost, including:
step S100: acquiring nitrogen oxide control parameters of a historical time period in an optimization cycle, wherein the nitrogen oxide control parameters comprise nitrogen oxide emission data, ammonia water consumption data and clinker production data;
the optimization cycle may be regarded as a calculation cycle of the environmental protection tax policy privilege, for example, when the environmental protection tax is calculated according to the monthly degree, the optimization cycle is a month, and the corresponding time period is a day;
the historical time period in the optimization cycle refers to the time that the current optimization cycle has elapsed, for example, when the method is implemented on 5 days in the month when the month is the optimization cycle and the days are the time periods, the historical time period in the optimization cycle refers to 4 days before the month;
the nitrogen oxide emission data can include nitrogen oxide emission concentration and nitrogen oxide emission amount, wherein the nitrogen oxide emission concentration can be acquired in real time according to a sensor arranged in a production workshop, the acquired value is regarded as an actual measurement value, and a converted value is acquired through oxygen content elimination conversion, wherein the converted value is the actual measurement value (21% -10%)/(21% -actual measurement oxygen content).
In general, the eco section processes the environmental tax in accordance with a reduced value when calculating the environmental tax.
The ammonia water consumption data and the clinker production data can be acquired in real time according to equipment in a production workshop.
The data may be collected once a day or hour, and stored after collection until extracted as needed for optimization.
Step S200: determining an optimal target value of the discharge amount according to the environmental protection cost;
the optimal target value can be manually confirmed and input by a manager according to historical experience and can be used as the optimal target value, or can be automatically analyzed and determined by a computer, for example, when the emission control is better N days before the month, the emission reduction is expected to reach a more favorable tax reduction gear at the end of the month, and the optimal target value is more favorably updated and adjusted to the next gear; or the target set at the beginning of the month is too high, so that the discharge amount is not controlled well in actual production, and a tax reduction gear needs to be adjusted downwards according to actual conditions in the middle of the month or at the end of the month.
The emission concentration limit value in the emission Standard of atmospheric pollutants for the Cement industry (GB4915-2013) is 320mg/m3For example, 70% of the limit is 224mg/m350% of the limit is 160mg/m3The optimal target value of the emission amount is set to 160mg/m at the beginning of the month3However, it is difficult to reduce the dosage to 160mg/m in the month according to the control condition at the beginning of the month3When the concentration is higher than the above range, the concentration is adjusted to 224mg/m as early as possible3It is advantageous to reduce the consumption of ammonia, and if the cost of reducing ammonia consumption is more than the increased 25% environmental tax, it is reduced in the total cost.
Referring to fig. 2, in the present embodiment, step S200 may include:
step S201: respectively calculating the real payment amount of the environmental protection tax when the emission concentration of the nitric oxide is at a first level, a second level and a third level according to the environmental protection tax deduction level;
the first, second and third levels may correspond to an emission concentration of 320mg/m, respectively, according to the limit of the aforementioned eco-tax policy3、224mg/m3And 160mg/m3；
The environment-friendly tax real payment amount is the environment-friendly tax due payment amount, and the deduction percentage is obtained;
the environment-friendly tax payment amount is 2.4 x nitrogen oxide emission amount/0.95, and the nitrogen oxide emission amount can be obtained by conversion according to the nitrogen oxide emission concentration and the flue gas flow;
the step is to calculate the emission concentration to be 320mg/m3The discharge amount of nitrogen oxides and the amount of the environmental tax to be paid are calculated, the environmental tax is not reduced, and the corresponding real amount is the amount of the tax to be paid; the emission concentration was calculated to be 224mg/m3The discharge amount of nitrogen oxides and the amount of the environmental tax to be paid are calculated, the environmental tax is collected according to 75%, and the corresponding real payment amount is 75% of the amount to be paid; calculating the discharge concentration of 160mg/m3The discharge amount of nitrogen oxides and the amount of the environmental tax to be paid are calculated, at the moment, the environmental tax is collected according to 50%, and the corresponding real payment amount is 50% of the amount to be paid;
step S202: estimating the ammonia water amount consumed if the nitrogen oxide emission concentration is to reach a first level, a second level and a third level according to the nitrogen oxide emission concentration of the previous time period or the average nitrogen oxide emission concentration of the historical time period;
in order to reduce the emission of nitrogen oxides, ammonia water is generally adopted to react and absorb the nitrogen oxides, so that if the emission concentration of the nitrogen oxides is limited to be lower, the more ammonia water is consumed, the ammonia water consumption amounts of different gears are respectively calculated, and the cost of the ammonia water is conveniently and directly compared;
in specific implementation, the actual emission concentration and the limit value of the previous time period are 320mg/m3、224mg/m3And 160mg/m3Deviations, especially at 224-320mg/m3The interval is either 160-224mg/m3In the interval, the situation of ammonia water consumption negative cost can occur, the negative cost reaction is that if a looser emission reduction standard is selected, the ammonia water consumption can be reduced in the later time, so that the emission concentration of nitrogen oxides is properly increased and is reduced to a gear with less environmental protection tax, at the moment, although the environmental protection tax is increased, the consumption cost of the ammonia water is reduced, and the situation of reducing the total cost can be achieved.
Step S204: respectively calculating the total cost of the first grade, the second grade and the third grade, wherein the total cost comprises the real payment amount of the environmental tax and the ammonia water consumption cost corresponding to the ammonia water amount;
step S205: and comparing the total cost of the first grade, the second grade and the third grade, and setting the nitrogen oxide emission concentration with the minimum total cost as an emission optimal target value.
The total cost of different tax reduction gears is estimated according to the actual production situation, so that the environmental tax cost and the ammonia water cost can be controlled in the optimal balance, and the optimized total cost is minimized.
The emission peak value per unit time may also be limited due to environmental tax reduction policy, for example, the emission concentration per hour cannot be higher than 350mg/m3Otherwise, the method is not exempted, the centralized emission of a production enterprise at a certain time is prevented, and therefore the substantial environmental protection effect cannot be achieved.
The embodiment can also refer to fig. 3, and after the initial setting of the optimal target emission amount, further embodiments are provided:
step S206: acquiring the emission amount of nitrogen oxides per unit time in a historical time period;
step S207: judging whether the discharge amount of the nitrogen oxides in each unit time exceeds a unit time discharge threshold value of the environment protection tax deduction grade corresponding to the discharge amount optimal target value;
if there is at least one nox emission per unit time exceeding the emission threshold per unit time, step S208 is executed: setting the optimal target value of the emission amount as the emission concentration of the nitrogen oxide of the last environmental protection tax deduction grade;
and returning to the step S207, determining whether the discharge amount still exceeds the discharge threshold of the previous level per unit time, and setting the corresponding level as the optimum discharge amount target value until the discharge amount per unit time is within the threshold.
And determining the environment protection tax deduction grade, and then making the emission index of the next time period according to the grade.
Step S400: according to the nitrogen oxide control parameters of the historical time period, calculating the nitrogen oxide emission index of the next time period in the optimization cycle under the optimal emission target value;
there are various ways to calculate the index, and this embodiment preferably implements the following:
step S411: calculating an average nox control parameter over a historical period of time;
the average nitrogen oxide control parameter is the total emission amount which is completed in the optimization period divided by the number of the past historical time periods, or the emission concentration of each time period is added and then divided by the number of the past historical time periods;
step S412: calculating the nitrogen oxide emission index I of the next time periodNOnext：
INOnext＝SNO×2-INOeven
Wherein S isNOFor an optimum target value of the discharge amount, INOevenIs the average nox control parameter.
Step S500: and outputting a nitrogen oxide emission index.
According to the method, the optimal balance point of ammonia water cost and environmental protection tax cost can be accurately mastered, and reasonable control indexes are determined, so that the environmental protection comprehensive cost (ammonia-containing water running cost and environmental protection tax cost) of clinker is reduced and controlled, and the following is the concrete project implementation data description:
table 1 is the cost statistics without the implementation of the method;
table 1: 2018-year NOx comprehensive cost data table
After the method is executed, monthly nitrogen oxide emission concentration indexes are formulated monthly, NOx emission data are tracked every day, and the NOx emission concentration control indexes on the same day are calculated and verified by using a nitrogen oxide emission accurate control table to guide operators to accurately implement control;
in the period, the requirements of ultralow emission and the like are executed by combining peak-staggering production arrangement and air pollution early warning, and the control indexes are adjusted in time to obtain a scheme with optimal comprehensive cost or execute different control schemes at different stages.
The monthly statistics can be seen in a 12-month-2020 nitric oxide emission accurate control statistical table shown in fig. 4, emission data is tracked and calculated in real time every day, the NOx control index is dynamically adjusted, and the monthly accumulated emission concentration is accurately controlled within the exemption target range, so that the target of lowest environmental protection comprehensive cost is achieved.
Finally, the cost comparison is obtained:
table 2: nox comprehensive cost data sheet
As seen from the comparison of the data in the table, the comprehensive cost of environmental protection is obviously reduced in 2020.
Through the analysis of data accumulated by project implementation, the emission concentration of nitrogen oxides is controlled at 224mg/m3When the clinker environmental protection expenditure is close to the critical value, the aggregate cost of the clinker environmental protection expenditure is accumulated to be 2.35 yuan/ton-clinker aggregateCompared with the comprehensive cost of the clinker environmental protection expenditure in 2019, the comprehensive cost is 2.71 yuan/ton-clinker aggregateReduced by 0.36 yuan/ton-clinker aggregateThe cost of the environmental protection expense is saved by 66.42 ten thousand yuan. (70% of the reduced emission concentration is lower than the limit value, and 75% is reduced to collect the environmental protection tax.)
And simultaneously comparing the emission reduction conditions of the nitrogen oxides:
table 3: NOx emission reduction
998 tons in 2019, 838 tons in 2020 (707 tons in emission in 1-10 months and 131 tons in emission temporary estimate in 11-12 months), and 160 tons in emission reduction in year-on-year basis.
Under the condition of equivalent clinker yield, the discharge amount of nitrogen oxides is reduced, and the method has better social benefit. In conclusion, the project has obvious economic benefit and social benefit after the method is implemented.
Example two:
referring to fig. 5, the embodiment provides a method for accurately controlling emission of nitrogen oxides based on environmental protection cost, which includes:
step S100: acquiring nitrogen oxide control parameters of a historical time period in an optimization cycle, wherein the nitrogen oxide control parameters comprise nitrogen oxide emission data, ammonia water consumption data and clinker production data;
step S200: determining an optimal target value of the discharge amount according to the environmental protection cost;
step S300: identifying whether there is a nitrogen oxide emissions specified limit;
if the specified limit value of the nitrogen oxide emission exists, obtaining the specified limit value of the nitrogen oxide emission, and setting the specified limit value of the nitrogen oxide emission as the nitrogen oxide emission index of the next time period;
if there is no nitrogen oxide emission specified limit, step S400 is performed: according to the nitrogen oxide control parameters of the historical time period, calculating the nitrogen oxide emission index of the next time period in the optimization cycle under the optimal emission target value;
step S500: and outputting a nitrogen oxide emission index.
Considering that there are temporary emission regulations (nitrogen oxide emission limits) in some cases, a proportion of certain periods requires strict control of the emission of pollutants within smaller limits (160 mg/m)3Even 120mg/m3) Therefore, when this limit is defined, the emission index of the next period can be limited to the limit without considering other factors, and the emission is prevented from exceeding the limit.
Due to the gradual improvement of the environmental protection policy, part of regions also charge emission right cost according to the emission of nitrogen oxides, for example, charge emission right cost of 1200 yuan per ton of nitrogen oxides, so that the emission right cost needs to be introduced for accounting the total cost, and the optimal target value of the emission is estimated more accurately.
In this embodiment, referring to fig. 6, step S200 may include:
step S201: respectively calculating the real payment amount of the environmental protection tax when the emission concentration of the nitric oxide is at a first level, a second level and a third level according to the environmental protection tax deduction level;
step S202: estimating the ammonia water amount consumed if the nitrogen oxide emission concentration is to reach a first level, a second level and a third level according to the nitrogen oxide emission concentration of the previous time period or the average nitrogen oxide emission concentration of the historical time period;
step S203: and respectively calculating corresponding nitrogen oxide emission right cost according to the corresponding nitrogen oxide emission amount when the nitrogen oxide emission concentration is in the first grade, the second grade and the third grade.
Step S204: respectively calculating the total cost of the first grade, the second grade and the third grade, wherein the total cost comprises the real payment amount of the environmental tax, the ammonia water consumption cost corresponding to the ammonia water amount and the nitrogen oxide pollution discharge right cost;
step S205: comparing the total cost of the first grade, the second grade and the third grade, and setting the nitrogen oxide emission concentration with the minimum total cost as an emission optimal target value;
step S206: acquiring the emission amount of nitrogen oxides per unit time in a historical time period;
step S207: judging whether the discharge amount of the nitrogen oxides in each unit time exceeds a unit time discharge threshold value of the environment protection tax deduction grade corresponding to the discharge amount optimal target value;
if there is at least one nox emission per unit time exceeding the emission threshold per unit time, step S208 is executed: setting the optimal target value of the emission amount as the emission concentration of the nitrogen oxide of the last environmental protection tax deduction grade;
and returning to the step S207, determining whether the discharge amount still exceeds the discharge threshold of the previous level per unit time, and setting the corresponding level as the optimum discharge amount target value until the discharge amount per unit time is within the threshold.
Optimizing the index of nitrogen oxide emission in the next time period in the cycle under the optimal target value of the emission, the preferred way of calculating the index in this embodiment is as follows:
step S421: calculating a total nitrogen oxide control parameter for a historical time period;
step S422: calculating NOx emissions for the next time periodDischarge index INOeven：
INOeven＝SNO×(n+1)-INOsum
Wherein S isNOFor an optimum target emission, n is the number of historical time periods, INOsumThe parameters were controlled for total nitrogen oxides.
The embodiment refers to a new influence factor, can be more suitable for different environmental protection policies, and correspondingly establishes the nitrogen oxide emission standard with better economic benefit and social benefit.
