Abstract

The invention discloses a DC composite tower sulfur dioxide treatment system. The DC composite tower sulfur dioxide treatment system comprises a DS multiphase desulphurization tower and a CST turbogrid tower, wherein the top end of the DS multiphase desulphurization tower is communicated with a boiler by virtue of a pipeline, and the lower end of the DS multiphase desulphurization tower is arranged on a settling pond and communicated with the settling pond; the lower end of the CST turbogrid tower is arranged on the settling pond and communicated with the settling pond; the top end of the CST turbogrid tower is connected with a draught fan by virtue of a pipeline, and the draught fan is communicated with a chimney by virtue of a pipeline; a sewage opening is formed in the lower part of the settling pond; the middle part of the settling pond accesses the upper part of the DS multiphase desulphurization tower by virtue of a circulating pump; and the pipelines between the draught fan and the chimney and between the boiler and the DS multiphase desulphurization tower are communicated by virtue of a circulating wind pipe. A DC composite tower solves the problem of secondary pollution caused by the emission of wet desulphurization exhaust gas carrying aerosol particles; and the DC composite tower sulfur dioxide treatment system reduces the floor occupation area when various single towers are used in serial connection, saves the investment expense and improves the system operation reliability.

Description

technical field

[0001] The invention belongs to the technical field of environmental protection equipment, and relates to a DC compound tower sulfur dioxide treatment system, in particular to an integrated desulfurization technology of a DS multiphase desulfurization tower and a CTS cross-flow tray. Background technique

[0002] The main component of flue gas pollutants discharged by industry is SO 2 and dust, causing serious harm to the atmospheric environment and human beings. The integrated technology of flue gas desulfurization and dust removal can be integrated into the process engineering, combining the two operating units of desulfurization and dust removal, which has high efficiency and low investment. The promotion of integrated technology of dust removal and desulfurization will improve the living environment, increase economic benefits and regional benefits Air quality plays an important role. The desulfurization system is located at the end of the flue and afte...
