Boiler electrostatic precipitator

Boiler electrostatic precipitator is an energy-saving flue gas purification equipment, which has the advantages of collecting dust, processing large amounts of flue gas, long service life, and low maintenance costs. In the current situation where environmental protection requirements are increasingly high, electrostatic precipitator has been widely used. Electrostatic precipitator emissions can reach up to 20 milligrams! Our electrostatic precipitator equipment not only improves the working efficiency of the equipment, but also reduces the usage load of electrostatic precipitator, prolongs the service life of the equipment, and reduces the emission concentration.

The electrostatic precipitator is a new product introduced and digested by our company, which has summarized the operating experience of domestic equipment. It has the characteristics of low resistance, uniform air distribution, stable operation, and dust removal. It is widely used in the purification of industrial waste gas and the recovery of useful substances in industries such as power, metallurgy, chemical, building materials, and light industry.

Principle of boiler electrostatic precipitator:

Its working principle is that when the smoke passes through the flue in front of the main structure of the electrostatic precipitator, the smoke carries a positive charge, and then the smoke enters the electrostatic precipitator channel with multiple layers of cathode plates. Due to the mutual adsorption between positively charged smoke particles and the cathode plate, the particulate smoke particles in the flue gas are adsorbed on the cathode. When the cathode plate is hit at regular intervals, the thick smoke particles fall into the ash hopper below the structure of the electrostatic precipitator under the dual effects of self weight and vibration, thus achieving the purpose of smoke particles in the flue gas. Due to the large power output of general units in thermal power plants, such as 600000 kW units, with an hourly coal consumption of about 180 tons, the amount of smoke and dust can be imagined. Therefore, the corresponding structure of the electrostatic precipitator is also relatively large. The cross-sectional size of the main structure of the electrostatic precipitator used in general thermal power plants is about 25-40 × 10-15m. If the height of the ash hopper is added to the 6-meter height and the height of the smoke transport space, the entire height of the electrostatic precipitator is above 35 meters. For such a large steel structure, not only the autonomous, smoke load, wind load, but also the static and dynamic analysis under seismic load need to be considered. At the same time, the stability of the structure must also be considered.
