Embodiment Construction
[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.
[0029] Example.
[0030] The wet electrostatic precipitator of a 1000MW coal-fired unit in a power generation company has been put into operation for 3 years, and it is necessary to predict the SO of the device at this time 3 removal efficiency. By collecting the design data of the wet electrostatic precipitator, determine the parameters such as the material of the anode plate, the design specific dust collection area, the design flue gas flow rate, and the design inlet flue gas volume, and collect online monitoring data on site to determine the inlet smoke temperature, inlet smoke concentration, and inlet SO 2 Concentration, inlet flue gas volume, by consulting the inlet SO 2 Concentration, inlet SO 3 Concentratio...

The invention discloses a coal-fired power plant wet electrostatic precipitator SO 3 A collaborative removal efficiency prediction method belongs to the field of industrial waste gas purification, environmental protection and energy. The present invention collects relevant data through data collection and on-site testing for specific wet electrostatic precipitators in coal-fired power plants, and determines the material of the anode plate, the specific dust collection area, the inlet smoke temperature, the flue gas flow rate, the inlet smoke concentration, and the inlet SO 3 Concentration and other parameters, and then determine the comprehensive performance correction coefficient according to the performance test results of the wet electrostatic precipitator after it is put into operation, and finally substitute the obtained results into the wet electrostatic precipitator SO of the coal-fired power plant 3 The removal efficiency prediction model calculates the SO 3 Predicted removal efficiency. This method has the advantages of system, accuracy, strong operability and real-time prediction, which can be used for the optimal operation of wet electrostatic precipitator and SO 3 It provides technical support for emission control, can produce significant environmental benefits, safety benefits and economic benefits, and has broad application prospects.
Description
technical field [0001] The invention belongs to the field of industrial waste gas purification, environmental protection and energy, in particular to a wet electrostatic precipitator SO for a coal-fired power plant 3 Synergistic removal efficiency prediction method. Background technique [0002] my country's coal-based energy structure will not change for a long time. Therefore, controlling the emission of coal-fired flue gas pollutants is an important task for my country's air pollution control. In the current situation where conventional flue gas pollutants in coal-fired power plants fully require ultra-low emissions, SO 3 Due to the relative lack of control methods, emissions are very harmful to the ecological environment and power production, and have attracted more and more attention from all parties. On the other hand, the wet electrostatic precipitators installed in some coal-fired power plants have been proved to have strong SO 3 Synergistic removal performance, b...
