Abstract

The invention discloses an electrostatic-metal ceramic filtering dust removal device for synergistic desulfurization and denitrification. The device comprises a shell, an air inlet is formed at one side of the upper end of the shell, a pressure gauge is arranged on the inner wall of the shell, an air outlet is formed at one side of the lower end of the shell, and the air outlet is connected with an induced draft fan; a discharge electrode is arranged at the center of the dust removal device, a dust collection electrode comprises two layers of metal ceramic sleeves, the diameters of filtering holes in the walls of the metal ceramic sleeves of every layer are different, and the electrode and the metal ceramic sleeves are fixed on an alloy plate; and a dust bucket is arranged at the lower endof the shell. The device has the advantages of simultaneous completion of dust removal, desulfurization and denitrification of flue gas, good flue gas treatment effect, high efficiency and resource saving.

Description

technical field [0001] The invention belongs to the field of flue gas purification, and specifically relates to an electrostatic-cermet filter and dust removal device for synergistic desulfurization and denitrification. Background technique [0002] With the rapid development of my country's modern industry, the problem of environmental pollution is increasing day by day, mainly because my country's main energy structure is coal combustion, and the flue gas emitted by coal combustion contains a large amount of dust, sulfur dioxide, nitrogen oxides and other impurities Therefore, it is imminent to control the emission of dust, sulfur dioxide and nitrogen oxides. For power plant flue gas dust removal and desulfurization and denitrification problems, predecessors have done a lot of experimental research, but the traditional purification system, dust removal device, desulfurization device, denitrification device can only work alone, the cost of operation and maintenance is high, ...
