AOD furnace produces a lot of high temperature dust in the smelting process, high temperature, large amount of dust, high temperature dust using the bag dust collector will burn the bag, and at the same time produce saturated steam in the cooling dust removal process. The smoke emission presents a "white plume". Does not meet the national low emission standards. AOD furnace flue gas dust removal and white removal process using wet desulphurization + wet electrostatic dust removal equipment, can better achieve the elimination of chimney outlet white smoke.
The flue gas of AOD furnace is collected and piped into the desulphurization system. The desulphurization process adopts wet desulphurization process. The desulphurization agent is lime removal. After the lime is matured in the ash tank, it flows to the comprehensive circulation tank for desulfurization reaction. Sulfur efficiency is 90%.
After desulphurization, the dust and flue gas enter the wet electrostatic precipitator. Under the action of high voltage static electricity, the corona cathode continuously radiates electrons, ionizing the gas between the electrodes into positive and negative ions. Particles such as dust and acid encounter electrons and generate charge. According to the principle of same sex repulsion and opposite sex attraction, the dust and acid fog droplets should move to the electrode with opposite electric polarity after charging. The positive ions move towards the corona pole, while the negative ions and electrons move towards the precipitating electrode, transferring their charge to the precipitating pole. Finally, it is discharged directly from the chimney.
It is also necessary to select different AOD furnace flue gas dust removal and whitening treatment solutions according to the actual situation of the user, so as to adapt to local conditions. We provide tailor-made affordable solutions in line with the enterprise itself. Reduced investment costs.
