Application of Pipe-type Electrostatic Precipitator in Flue Gas Treatment
The existing flue gas treatment process of the boiler tail in domestic coal-fired power plants is generally composed of denitrification, dust removal and desulfurization, and the flue gas enters the chimney directly after wet desulfurization. Among them, denitrification is used to remove NOX, pipeline electrostatic precipitator to remove dust, wet desulfurization to remove SOX.
Because the pipeline electrostatic precipitator can solve the gypsum rain and blue smoke problem caused by wet desulfurization, alleviate the corrosion of downstream flue and chimney, and save the anticorrosion cost. Its performance is stable, reliable and high efficiency. It can effectively collect fine particles, heavy metals, organic pollutants and so on. The emission of smoke and dust can reach 10 mg/m3 or even 5 mg/m3 below. It can realize ultra-low emission and thoroughly solve the problem of chimney discharge.
The pipeline electrostatic precipitator has the advantages of high dust removal efficiency, low pressure loss, simple operation, low energy consumption, no moving parts, no secondary dust emission, low maintenance cost, short production shutdown period, can work below the dew point temperature of flue gas, can be combined with other flue gas treatment equipment because of its compact structure, and diversified design forms. Advantage.
In a pipe electrostatic precipitator, water mist coagulates the dust and charges it together with the dust in the electric field. The water mist collected on the plate forms a water film, which makes the plate clean and keeps the plate clean. At the same time, because of the decrease of flue gas temperature and the increase of humidity, the specific resistance of dust drops greatly, so the working state of the pipeline electrostatic precipitator is very stable.http://www.icleairs.com/
