The dust collector can filter out the millimeter-scale coarse particle dust in the flue gas, but it can no longer meet the needs of today's environmental protection, especially today when the smog seriously affects people's lives, the dust collector is suitable for SO 2 and the dust is powerless

The invention relates to a desulphurization, dust removal and haze purification device for flue gas. The device comprises a first dust-removal desulphurization chamber, a second dust-removal desulphurization chamber, a haze removing chamber and a refined filtration chamber which are communicated in order, wherein a first separating plate and a second separating plate are respectively arranged in the first dust-removal desulphurization chamber and the second dust-removal desulphurization chamber; hollow adsorbing balls are respectively piled up above the first separating plate and the second separating plate; a storage pool is arranged below the haze removing chamber and is filled with emulsion for generating foams; a third separating plate is arranged in the haze removing chamber; a water filter is arranged above the third separating plate; a fourth separating plate is arranged in the refined filtration chamber, and steel balls are piled up above the fourth separating plate. The device adopts the structure of four-level purification, SO2 and dust in flue gas and tiny dust with the PM value of less than or equal to 2.5 are removed completely, the requirement for the conventional environmental protection can be satisfied, the flowing rate of water drops can be controlled below 0.01%, the escaping rate of the tiny dust with the PM value of less than or equal to 2.5 is quite low, and therefore the life of people cannot be affected by haze. The device is especially suitable for the flue gas and dust removing for factories and mines and the dense smoke treatment for electric furnaces during steelmaking.
Description
technical field [0001] The invention belongs to the technical field of exhaust gas purification devices, and in particular relates to a flue gas desulfurization, dust removal and haze purification device, which is suitable for yellow smoke treatment in factories and mines that generate flue gas dust and in electric furnace steelmaking. Background technique [0002] Traditionally, in order to filter the dust in the flue gas of the kiln, the commonly used method is the chamber type water film dedusting method. The shower device sprays the flue gas entering the dust removal chamber before discharging it. Using this method, although part of the fine particle dust in the flue gas can also be removed, because the dust in the flue gas settles after being wetted by the water film in the air, it is still difficult for the dust that has not been soaked. It can't filter out, and the dust removal effect is not good. In addition, this dust removal method requires a huge dust removal ro...
