Converter gas flue gas conditioning system and flue gas conditioning method thereof

Abstract

The invention provides a converter gas flue gas conditioning system and a flue gas conditioning method thereof in order to solve the problems that in the prior art, pollution is heavy and the cost ishigh when a chemical agent is used for flue gas conditioning, and due to the fact that converter gas belongs to flammable and combustible gas, conditioning of the conductivity of flue gas and dust through atomization of compressed air and water is not suitable, and belongs to the technical field of converter gas dedusting systems. The system comprises a water inlet pipeline and a nitrogen pipeline, nitrogen and water or water vapor are mixed to atomize the water, the mixed and atomized water is introduced into an inlet of an evaporative cooler through a pipeline, the atomized water is furthervaporized in the evaporative cooler, water molecules are combined with particles in the flue gas, the conductivity of the dust particles in the flue gas is changed, the dust is easier to charge afterentering an electric precipitator, and the chemical property of the nitrogen is inactive, so that the risk of explosion when the nitrogen makes full contact with the flue gas is avoided.

Description

technical field [0001] The invention belongs to the field of converter gas dedusting systems, and in particular relates to a converter gas flue gas conditioning system and a flue gas conditioning method. Background technique [0002] Converter gas electric dust removal system is a special special environmental protection equipment. The working conditions of the converter gas are complex, the characteristics of the dust in the flue gas vary greatly, and the specific resistance of the dust fluctuates in a wide range, which leads to a decrease in the charging ability of the electrostatic precipitator to the dust in the flue gas, and the dust removal efficiency of the dust collector cannot be achieved. In severe cases, after the dust enters the electrostatic precipitator, back corona and corona sealing will occur, and frequent high voltage breakdowns will occur inside the electric field. In order to increase the conductivity of the dust in the flue gas, it is generally used to ...

AI Technical Summary

Problems solved by technology

[0005] The invention aims at the problem of high pollution and high cost in the prior art of using chemical agents to carry out flue gas conditioning, and converter gas is an inflammable and explosive gas, so it is not suitable to use compressed air and water for atomization for conditioning To solve the problem of conductivity of flue gas dust, provide a safer flue gas conditioning system and its conditioning method
