Problems solved by technology

[0004] The assessment standard of the power plant's environmental protection electricity is the average value of pollutants discharged within one hour, and when the environmental protection equipment of the power plant is abnormal and the unit starts and stops, the total discharge pollutant data will always exceed the environmental protection requirement value for a short time, so In the existing technology, it is difficult to ensure that the pollutant data of the total discharge outlet will not exceed the standard during the abnormal failure of the environmental protection equipment of the power plant and the start-up and stop of the unit, and it is difficult to pass the assessment every time

Embodiment 1

[0022] Such as figure 1 As shown, the power plant pollutant discharge value prediction method includes the following steps, the pollutants use sulfur dioxide as an index, and measure SO2 per minute 2 The actual emission value will be SO per minute 2 The actual emission value is accumulated, and the SO 2 The specified total emission value minus the cumulative value of the completed emission value is obtained to obtain the completed emission value in the remaining time, and the completed emission value in the remaining time is divided by the remaining minutes to obtain SO 2 emission forecast. Measure SO per minute 2 When the actual emission value starts from the first minute of each hour.

Embodiment 2

[0024] The method for predicting the discharge value of pollutants in a power plant includes the following steps: measure the actual discharge value of pollutants per minute, accumulate the actual discharge value of pollutants per minute, and subtract the accumulated value of the completed discharge value from the total discharge value of pollutants per hour to obtain the remaining Time to complete the discharge value, and divide the remaining time to complete the discharge value by the remaining minutes to get the predicted value of pollutant discharge. When measuring the actual emission value of pollutants per minute, it starts from the first minute of each hour.

Abstract

The invention provides a method for predicting a pollutant emission value of a power plant and relates to the technical field of the power plant. The method is characterized by comprising steps as follows: an actual pollutant emission value every minute is measured and accumulated, a value of emission to be completed in remaining time is obtained by subtracting an accumulated value of completed emission values from a stipulated total pollutant emission value every hour, and a prediction value of pollutant emission is obtained by dividing the value of emission to be completed in the remaining time by remaining minutes. With the adoption of the method, an hourly average of completion of environmental protection indexes does not exceed the standard when environmental protection equipment is abnormal or during starting and stopping of a unit, the calculation is simple, the reliability is high, and environmental protection and energy conservation are facilitated.

Description

[0001] Technical field: [0002] The invention relates to the technical field of power plants, in particular to a method for predicting the discharge value of pollutants in power plants. [0003] Background technique: [0004] The assessment standard of the power plant's environmental protection electricity is the average value of pollutants discharged within one hour, and when the environmental protection equipment of the power plant is abnormal and the unit starts and stops, the total discharge pollutant data will always exceed the environmental protection requirement value for a short time, so In the existing technology, it is difficult to ensure that the pollutant data of the total discharge outlet will not exceed the standard during the abnormal failure of the environmental protection equipment of the power plant and the start-up and stop of the unit, and it is difficult to pass the assessment every time. [0005] Invention content: [0006] The technical problem to be so...
