Embodiment Construction

[0016] refer to figure 1 It is an embodiment of a dust removal and desulfurization co-processing device of the present invention. A dust removal and desulfurization co-processing device includes a tower body 1, a flue gas inlet 2 is provided at the lower part of the tower body 1, and a flue gas inlet 2 is provided at the top of the tower body 1. Outlet 9, the tower body 1 is provided with a first-level flue gas dedusting and desulfurization area, a second-level flue gas dedusting and desulfurization area and a demisting device 8 in sequence according to the flue gas flow direction;

[0017] The primary flue gas dedusting and desulfurization zone includes a porous distribution plate 17, a synergistic ring 18 and at least two primary spray layers 6. The porous distribution plate 17 is arranged in the tower body 1 above the flue gas inlet 2, and a The first-level spray layer 6 is arranged in the tower body 1 above the porous distribution plate 17, and a synergistic ring is arrang...

Abstract

The invention discloses a synergistic treatment device for dust removing and desulphurization. The synergistic treatment device adopts the structure that a primary smoke dust removing and desulphurization area, a secondary smoke dust removing and desulphurization area and a defogging device are sequentially arranged in a tower body in the smoke flowing direction; a porous distribution plate of the primary smoke dust removing and desulphurization area is arranged in the tower body above a smoke inlet; primary spraying layers are arranged in the tower body above the porous distribution plate; a synergistic ring I is arranged between two adjacent primary spraying layers; a liquid collection disc of the secondary smoke dust removing and desulphurization area is positioned in the center of the tower body above the primary spraying layer; a ring-shaped plate is arranged in the tower body above the liquid collection disc; the inner diameter of the ring-shaped plate is smaller than the outer diameter of the liquid collection disc; secondary spraying layers are fixed above the ring-shaped plate in the tower body; a synergistic ring II is arranged between two adjacent secondary spraying layers. The synergistic treatment device has the advantages that dust removing and desulphurization are subjected to hierarchical and synergistic treatment, and a desulphurization spraying tower can be used for achieving efficient dust removing and desulphurization simultaneously, so that the investment and the operation cost can be reduced.

Description

technical field [0001] The invention relates to a dust removal and desulfurization co-processing device. Background technique [0002] According to the "Coal Power Energy Conservation and Emission Reduction Upgrading and Transformation Action Plan (2014-2020)", new coal-fired generating units in the eastern region are required to basically meet gas turbine standards, and the emission limit is smoke and dust under the condition of a reference oxygen content of 6%: 10mg / m 3 , SO 2 : 35mg / m 3 ; Some local governments have issued stricter policies and regulations. Due to limited environmental capacity and other reasons, some coal-fired power plants in the Yangtze River Delta and Pearl River Delta have referred to the standard limits of gas turbines, requiring the emission limit to be smoke and dust: 5mg / m 3 , SO 2 : 35mg / m 3 . When the sulfur content of coal combustion is low, such as the FGD inlet SO2 concentration is lower than 3000mg / m 3 The unit, in order to achieve 35...
