Compound efficient energy-saving desulfurization, denitrification and dedusting integrated purifying column

Abstract

The invention discloses a compound efficient energy-saving desulfurization, denitrification and dedusting integrated purifying tower and relates to environmental protection equipment. The compound efficient energy-saving desulfurization, denitrification and dedusting integrated purifying tower comprises a desulfurization device and a denitrification device. The desulfurization device comprises a desulfurization tower and a main desulfurizing agent pipe, the inner upper end of the desulfurization tower is connected with a grating filtering layer, purifying filler is arranged on the grating filtering layer, the main desulfurizing agent pipe is vertically fixed in the desulfurization tower through a supporting component, and a plurality of nozzles are connected to the main desulfurizing agent pipe along the height direction. The denitrification device comprises a denitration tower and a spherical gas surge tower, the gas surge tower is fixedly connected to the upper end of the denitration tower, the denitration tower is fixed in an inner cavity of the denitration tower through a connecting component, and a denitration oxidizing agent pipeline is arranged between the denitration tower and the desulfurization tower and is provided with a plurality of liquid outlet holes. A flue gas inlet and a flue gas outlet are formed in the lower end of the desulfurization tower, the flue gas inlet passes through the denitration tower to be communicated with an inner cavity of the desulfurization tower, and the flue gas outlet is communicated with the inner cavity of the denitration tower. The compound efficient energy-saving desulfurization, denitrification and dedusting integrated purifying tower has the advantages of good purifying effect and low cost.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to a purification device for smoke and sulfur dioxide produced in chemical industry, boiler, coking, power plant, glass factory and the like. Background technique [0002] In recent years, the problem of air pollution has become more and more serious. As a large developing country, my country will still face the serious situation of increasing air pollution for a long time to come. With the continuous increase of energy demand, the pollution problem caused by flue gas emission has become increasingly prominent, and the problem of atmospheric environmental pollution control has attracted extensive attention from all over the world. It is fundamental to develop high-efficiency, energy-saving, and cost-effective flue gas purification equipment and technologies. address environmental issues. [0003] Industrial flue gas is the main factor of air pollution to form acid rain, among w...

AI Technical Summary

Problems solved by technology

At present, many domestic purification equipment have problems such as high investment, high operating cost, consumption of high-quality limestone resources, waste water needs to be treated and discharged, and equipment is easily damaged, which has brought a heavy burden to the enterprise.
