Catalyst, preparation method of catalyst, and flue gas CO removal-white smoke elimination system and method

Abstract

The invention provides a catalyst, a preparation method of the catalyst, a flue gas CO removal and white smoke elimination system and a flue gas CO removal and white smoke elimination method. The system comprises a demister, a dehumidification rotating wheel, an intelligent gas detection module, a flow guide module, a heating module, a catalytic oxidation module and a flue gas backflow module; thedemister is arranged at a flue gas inlet, and a dehumidification rotating wheel, a flow guide module, a flue gas heating module, a catalytic oxidation module and a flue gas backflow module are sequentially arranged on a flue of the dust remover. The system is located behind wet desulphurization, dry denitration or semi-dry desulphurization and in front of a chimney, the flue gas treatment processis not changed, the transformation degree is small, the spatial applicability is high, the energy consumption in the operation process is low, efficient CO removal and flue gas white elimination canbe completed automatically, and the operation cost is low. According to the system, the CO and CO2 concentration sensors are installed at the flue gas inlet and the flue gas outlet, whether the catalytic oxidation module works normally or not can be intelligently evaluated, meanwhile, the flue gas temperature in the system can be evaluated, and the white smoke eliminating effect is guaranteed.

Description

technical field [0001] The invention relates to the field of flue gas CO removal, in particular to a catalyst and a preparation method, and a flue gas CO removal-whitening system and method. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Since the industrial revolution, metallurgy, steelmaking, and other industries have developed rapidly, satisfying the growth of the world economy and increasing environmental pollution. Heavy industrial enterprises will produce a large amount of pollutants while consuming a large amount of fossil energy, such as the ore used in metallurgy Most of the raw materials contain sulfur, and a large amount of SO will be produced during the smelt...

AI Technical Summary

Problems solved by technology

[0004] Before the flue gas is discharged, it usually goes through a series of purification procedures, such as desulfurization, denitrification, etc., but there is still a considerable amount of CO at the end of the flue gas. If the CO is directly discharged into the atmosphere without treatment, it will not only pollute the environment, It's also a waste of energy

At the same time, the current flue gas discharge temperature is high, which not only causes a lot of waste of heat energy, but also contains a large amount of water vapor in the flue gas, which will form white feathers when it is directly discharged at low altitude, which not only seriously affects the nearby residential residents, but also causes another cause of smog (forms aerosol)

At present, flue gas whitening is a relatively novel treatment process for large-scale concentrated industrial flue gas treatment, but the existing flue gas treatment has a low treatment efficiency for flue gas whitening, and flue gas dewatering and whitening The effect is often not good, and most of the prior art is to improve one of the above-mentioned problems, lacking a related whole system
