Description

Technical Field

[0001] The present disclosure relates to the field of coal-fired power technology, and in particular, to a method, device, electronic equipment and program for controlling the concentration of condensable particulate matter. Background Art

[0002] In the prior art, the control of condensable particulate matter of coal-fired units mostly relies on fixed emission control equipment, such as electrostatic precipitators, bag filters, and desulfurization and denitrification devices. These devices are often only optimized for full load or near full load conditions during design, and have limited flexible control capabilities under deep peak load conditions. During deep peak load, when the coal-fired unit responds to peak load and reduces the output load, the furnace temperature decreases accordingly, resulting in incomplete combustion of the fuel, increasing the emission of unburned substances and fuel nitrogen compounds, and causing the initial emission concentration of condensable particulate matter to increase. If the condensable particulate matter reduction equipment is still operating in a state of complete fuel combustion at this time, it may cause the condensable particulate matter reduction equipment to be unable to reduce the condensable particulate matter concentration to below the emission standard, thereby exacerbating the problem of air pollution. On the contrary, when the coal-fired unit responds to peak load regulation and increases its output load, the fuel is completely burned and the initial emission concentration of condensable particulate matter is reduced. If the condensable particulate matter reduction equipment is still operating in a state of incomplete fuel combustion at this time, it may lead to a reduction in the efficiency of the condensable particulate matter reduction equipment, resulting in a waste of equipment resources. This is a technical problem that urgently needs to be solved. Summary of the invention

[0060] Through the above technical scheme, based on the environmental parameters of the target area and the operating parameters of the coal-fired unit, the predicted emission concentration of condensable particulate matter in the target area is determined, and the predicted emission concentration is compared with the standard emission concentration to determine the reduced emission concentration of condensable particulate matter in the target area, so as to determine the operating parameters of the emission reduction equipment through the reduced emission concentration, thereby controlling the condensable particulate matter concentration in the target area. By utilizing the pre-constructed condensable particulate matter concentration prediction model, the predicted emission concentration of condensable particulate matter is predicted according to real-time data, thereby avoiding excessive emissions and reducing environmental pollution. This not only helps to improve the environmental protection performance of the coal-fired unit, but also reduces operating costs and improves economic benefits.

[0061] Figure 2 is a flow chart showing another method for controlling the concentration of condensable particulate matter according to an exemplary embodiment. Figure 2 As shown, step S101 includes:

[0062] In step S1011, the output time window and output load of the coal-fired unit during deep peak regulation are obtained.

For example, coal-fired unit A has different operating parameter records under different output loads. For example, when the output loads are 200MW, 300MW, and 400MW, the corresponding operating parameters are different. In the output load-parameter association table, each output load value corresponds to one or more records. By inputting the output load, the corresponding operating parameters can be quickly and accurately located.

The proportion analysis refers to calculating the proportion of the exceeding standard data in the entire output time window to evaluate the severity and impact range of the exceeding standard problem. The higher the proportion, the more serious the exceeding standard problem is, and more attention and resolution are required. The first concentration analysis data is compared with the first condensable particulate matter concentration analysis threshold, and the second concentration analysis data is compared with the second condensable particulate matter concentration analysis threshold to determine the condensable particulate matter concentration emission result of the emission reduction equipment under the control of the operating parameters.

For example, when the condensable particulate matter concentration emission result is unqualified, it is necessary to further adjust the operating parameters of the emission reduction equipment or check the equipment status to reduce the emission concentration of condensable particulate matter. When the condensable particulate matter concentration emission result is qualified, it means that the emission condition under the current operating parameter control is good and can be maintained.

[0109] The first concentration analysis data is compared with a preset first concentration analysis threshold, and the second concentration analysis data is compared with a preset second concentration analysis threshold, to determine the condensable particulate matter concentration emission result of the coal-fired unit under the control of the operating parameters of the emission reduction equipment during the deep peak regulation process;

[0110] When the condensable particulate matter concentration emission result is qualified, the emission reduction device operates with the operating parameters;

[0111] When the condensable particulate matter concentration emission result is unqualified, the operation parameters of the emission reduction device are determined by determining the reduced emission concentration of the condensable particulate matter to control the operation of the emission reduction device.

[0112] Through the above technical scheme, based on the environmental parameters of the target area and the operating parameters of the coal-fired unit, the predicted emission concentration of condensable particulate matter in the target area is determined, and the predicted emission concentration is compared with the standard emission concentration to determine the reduced emission concentration of condensable particulate matter in the target area, so as to determine the operating parameters of the emission reduction equipment through the reduced emission concentration, thereby controlling the condensable particulate matter concentration in the target area. By utilizing the pre-constructed condensable particulate matter concentration prediction model, the predicted emission concentration of condensable particulate matter is predicted according to real-time data, thereby avoiding excessive emissions and reducing environmental pollution. This not only helps to improve the environmental protection performance of the coal-fired unit, but also reduces operating costs and improves economic benefits.
