Environment-friendly device and method for eliminating desulphurization white plume

Abstract

The invention relates to the technical field of power transmission and transformation wires, in particular to an environment-friendly device and a method for eliminating desulphurization white plume.The method comprises the following steps: leading to-be-treated flue gas out of a boiler air neck device, and mixing the to-be-treated flue gas with ozone gas prepared by an ozone generator through anozone grid; conveying a mixture into a desulphurization absorption tower along with the flue gas; after entering the desulphurization absorption tower, carrying out full contact of the flue gas witha desulfurizing agent in the desulphurization absorption tower; carrying out reaction curing of the flue gas with the desulfurizing agent, conveying obtained cured desulfurized ash into a dust removeralong with the flue gas, and collecting the desulfurized ash in the flue gas and ash generated after boiler combustion; discharging the collected desulfurized ash residues and a part of ash generatedafter boiler combustion, mixing a part of ash with slaked lime, humidifying, returning to the desulfurizing absorption tower, and keeping the gas-solid ratio in the desulphurization absorption tower.The device has the advantages that white plume is eliminated in an ozone dry desulfurization mode, water consumption of a desulfurization and dust removal system is prevented from being increased, activated carbon of the desulfurization absorption tower further plays a role in desulfurization, desulfurization efficiency and effect are improved, and the device is energy-saving, environment-friendly, simple in structure, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of transmission and transformation wires, in particular to an environmental protection device and method for eliminating desulfurization white smoke. Background technique [0002] At present, the wet desulfurization and dust removal process is widely used in industrial flue gas treatment and has achieved good results. However, the phenomenon of white smoke emitting from the chimney has not been well resolved. [0003] In fact, the so-called 'white smoke' is actually mist droplets formed by the condensation of water vapor. Water vapor is a colorless, transparent gas that condenses into water droplets when exposed to heat. Water droplets are a kind of granular liquid with a particle size within the range recognized by the human eye. When the particle size is small, it is often called fog. [0004] The desulfurization tower contains a large amount of high-temperature water vapor, which gushes out from the ch...

AI Technical Summary

Problems solved by technology

[0005] 1. The thick white smoke can easily make the surrounding residents mistakenly regard it as a pollutant, causing unnecessary disputes

[0006] 2. The white smoke is composed of water droplets, and after gushing out of the chimney, it falls around and forms raindrops, corroding the surrounding desulfurization and dust removal equipment, and a large amount of water is lost, which increases the water consumption of the desulfurization and dust removal system.
