Embodiment

[0034] This embodiment provides a carbon monoxide treatment process, which is carried out on a reactor, and the reactor is provided with a bulk ore bed, and the bulk ore includes at least Fe 2 o 3 , the bulk ore bed comprises a first bulk ore bed;

[0035] Specifically, the reactor itself has a certain accommodation space, so as to realize the storage of bulk ore deposits. The reactor itself can be fixed or movable, and when the fixed setting is adopted, the equipment for introducing flue gas is also fixed. When the reactor itself is set in a mobile state, the equipment for introducing flue gas moves together with the reactor.

[0036] Described processing technology comprises the steps:

[0037] Judging the temperature of bulk ore deposits;

[0038] In this embodiment, in the bulk ore deposit, the Fe 2 o 3 The content is 50%-60%. Bulk ore can be sintered ore, hematite lump ore, pellet ore, etc. 2 o 3 Minerals that are mainly reducible substances such as calcium ferrite...

Abstract

The carbon monoxide treatment process provided by the present invention is carried out on a reactor, and the reactor is provided with a bulk ore bed, and the bulk ore at least includes Fe 2 o 3 , the bulk ore bed includes the first bulk ore bed, and the processing technique includes the steps of: judging the temperature of the bulk ore bed; smoke. to contain Fe 2 o 3 The bulk ore deposit is used as a carrier, making full use of Fe 2 o 3 Extremely reactive characteristics, passing CO-containing flue gas through bulk ore deposits and Fe 2 o 3 Reaction, so as to achieve the purpose of CO removal, especially suitable for the removal of low-concentration carbon monoxide. Therefore, through the process steps provided by the present invention, the CO removal operation can be effectively realized.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a carbon monoxide treatment process. Background technique [0002] For the steel industry, carbon monoxide accounts for a large part of the exhaust gas it produces. Especially in the early sintering stage, the carbon monoxide produced by the sintering process accounts for roughly 20% of the total carbon monoxide emissions. Carbon monoxide itself has certain toxicity. Once it is inhaled by workers or ordinary citizens during the production process, it will lead to poisoning and further Hazard to life safety. [0003] In the prior art, in order to avoid adverse effects on the external environment, the carbon monoxide produced in the smelting process usually adopts re-burning technology, absorbents, strong oxidants, and catalyst removal processes. Although the CO catalytic oxidation method treats low-concentration CO is more efficient, but noble metal catalysts are pro...
