To the flue gas dust removal and SOx/NOx control problem of power plant, the predecessor has done a large amount of experimental research, however, traditional clean system, dust collector, desulphurization unit, denitrification facility only can work alone, and the operation is with high costs of maintaining, removes dust simultaneously and SOx/NOx control can practice thrift running cost and occupation of land space greatly, improves the efficiency that the smoke and dust was handled simultaneously.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a static-cermet filters dust collector in coordination with SOx/NOx control to solve the problem that provides among the above-mentioned background art.
The utility model discloses an electrostatic-metal ceramic filtering dust removal device for coordinated desulfurization and denitrification, which comprises a shell, wherein an air inlet is arranged on 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 arranged on one side of the lower end of the shell, and the air outlet is connected with a draught fan; the center of the dust removing device is provided with a discharge electrode, the dust collecting electrode is provided with two layers of metal ceramic sleeves, the aperture of a filter hole on the wall of each layer of metal ceramic sleeve is different, and the electrode and the metal ceramic sleeves are fixed on an alloy plate; the lower end of the shell is provided with an ash bucket.
Preferably, the metal ceramic sleeve is divided into an inner layer and an outer layer, the inner layer is a metal ceramic filter cylinder with good conductivity, and the filter pore diameter on the cylinder wall is smaller, so that the electrostatic-filtration composite dust removal of dust in flue gas is realized; outer cermet sleeve filters aperture great, and the resistance is less when the flue gas after the dust removal passes through, and the outer section of thick bamboo wall and filter downthehole desulfurization denitration catalyst that adheres to of straining is strained to the skin, and the flue gas after the dust removal can be SOx/NOx control simultaneously when straining a section of thick bamboo through the outer layer.
Compared with the prior art, the beneficial effects of the utility model are as follows: according to the electrostatic-cermet filtering dust removal device with the synergistic desulfurization and denitrification functions, after flue gas enters from the air inlet, under the action of the discharge electrode, dust in the flue gas is charged, the inner-layer cermet cylinder is grounded to serve as a dust collection electrode, the charged dust in the flue gas is continuously collected, and preliminary dust removal on the flue gas is completed. The inner metal ceramic sleeve has air permeability and dust resistance, and can further filter smoke to further remove dust. The desulfurization and denitrification catalyst is attached to the filter holes in the wall of the outer-layer metal ceramic sleeve, and the flue gas after dust removal reaches the catalyst to react with the catalyst, so that the concentration of sulfur dioxide and oxynitride in the flue gas is reduced, and the purification of the flue gas is completed. The utility model discloses a dust removal and SOx/NOx control's is effectual, efficient, resources are saved.
