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 in 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 Concentration, SO...

The invention discloses a method for predicting SO3 cooperative removal efficiency of a wet electrostatic dust collector of a coal-fired power plant, and belongs to the field of industrial waste gas purification environmental protection and energy. According to the invention, data collection, on-site test and other work are carried out on the wet electrostatic dust collector of the specific coal-fired power plant to collect related data; the method further includes determining parameters such as anode plate material, specific dust collection area, inlet smoke temperature, smoke flow rate, inlet smoke concentration, inlet SO3 concentration and the like; and determining a comprehensive performance correction coefficient according to a performance test result after the wet electrostatic dustcollector is put into operation, and finally substituting the obtained result into the SO3 removal efficiency prediction model of the wet electrostatic dust collector of the coal-fired power plant forcalculation to obtain an SO3 removal efficiency prediction value. The method has the advantages of systematicness, accuracy, high operability and real-time prediction, can provide technical support for optimized operation of the wet electrostatic dust collector and emission control of SO3, can generate remarkable environmental protection benefits, safety benefits and economic benefits, and has awide application prospect.
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...
