Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to a multi-signal optimized energy-saving electric dust removal control method. Background technique [0002] Electrostatic precipitator is an essential supporting equipment for thermal power plants. Its function is to remove the particulate smoke and dust in the exhaust gas of coal-fired or oil-fired boilers, thereby greatly reducing the amount of smoke and dust discharged into the atmosphere, which is to improve environmental pollution. , important environmental protection equipment to improve air quality. Its working principle is that when the flue gas passes through the flue in front of the main structure of the electrostatic precipitator, the dust is positively charged, and then the flue gas enters the channel of the electrostatic precipitator with multi-layer cathode plates. Due to the mutual adsorption between the positively charged dust an...

Problems solved by technology

[0003] With the increasingly stringent national environmental protection control policies, ultra-low emissions have become a new benchmark for coal-fired power generation units. In order to reduce dust emissions from power plants, factories must use a variety of dust removal equipment including electrostatic precipitators. In order to achieve ultra-low Emission standards, full-load operation of the electrostatic precipitator consumes a lot of power and energy consumption, which will have a certain degree of impact on the production efficiency of the power plant and cause unnecessary waste of energy. The equipment is transformed and optimized to minimize the high energy consumption of the electrostatic precipitator due to various unreasonable factors without reducing the dust removal efficiency and requirements
