Description
Technical Field
The utility model belongs to the technical field of exhaust-gas treatment, especially, relate to a be used for flue gas desulfurization export dust removal whitening device.
Background
The environment and the development are problems facing the human society for a long time, currently, in the electric energy structure of China, coal and electricity account for about three quarters, and the coal and electricity account ratio can not change greatly in a long period of time in the future. The dust and sulfur dioxide generated by coal combustion are main atmospheric pollutants, and with the improvement of national environmental protection standards, each coal combustion unit starts to carry out ultra-low emission modification, the dust in the flue gas is mainly removed by electrostatic dust collection or cloth bag dust collection, and the sulfur dioxide is removed by wet desulphurization; however, the dust concentration in the flue gas after passing through the desulfurizing tower is higher than the national emission standard, and wet desulphurization causes the flue gas to contain a large amount of water vapor, and white smoke is generated at the outlet of the chimney, so that the vision is affected and the waste of the water vapor is generated, and therefore, the dust removal and whitening removal after the desulphurization become problems which are urgently needed to be solved by the flue gas treatment industry. In the prior art, wet electric dust removal is adopted after wet desulphurization, although the dust concentration can reach the standard and be discharged, the operation and maintenance cost is high, and white smoke cannot be removed.
Chinese patent No. 2016206920473, "a dust and mist removing device for flue gas desulfurization tower outlet", discloses a dust and mist removing device that relies on flue gas velocity of flow to drive the rotation of blade, and this kind of device needs certain flue gas velocity of flow, and if the lower flue gas volume of boiler load is few, then can not drive the high-speed rotation of device and produce centrifugal force and make white cigarette and dust condense and get rid of. In addition, the device reduces the flow area in order to ensure the flow velocity passing through the device, increases the smoke resistance, and has high operating cost and poor effect.
