Embodiment

[0034] In this embodiment, a carbon monoxide treatment process is carried out on the reactor, and a bulk ore is provided on the reactor, and at least there is at least Fe. 2 O 3 The bulk deposit includes a first bulk deposit;

[0035] Specifically, the reactor itself has a certain accommodating space, thereby achieving storage of the bulk deposit. The reactor itself may be fixed, or may be disposed in a moving position, and when a fixed setting is employed, the device that passes into the flue gas is also fixed. When the reactor itself is disposed, an access to the flue gas is moved along with the reactor.

[0036] The processing process includes the following steps:

[0037] Judging the temperature of the bulk deposit;

[0038] In this example, in the bulk ore, the Fe 2 O 3 The content is 50% -60%. The bulk mine can be a sintered mine, or it can be a hematite ore mine, a ball or other in FE. 2 O 3 , Minerals such as calcium-calcium and other minerals, these minerals themselves hav...

Abstract

The invention provides a carbon monoxide treatment process, which is carried out on a reactor, wherein the reactor is provided with a bulk mineral deposit, the bulk mineral at least comprise Fe2O3, and the bulk mineral deposit comprises a first bulk mineral deposit. The treatment process comprises the following steps: judging the temperature of a bulk mineral deposit; and when the temperature of the bulk mineraldeposit is higher than a working temperature value, introducing flue gas containing carbon monoxide into the bulk mineraldeposit. According to the present invention, flue gas containing CO is subjected to a reaction with Fe2O3 through a bulk mineral deposit by using the Fe2O3-containing bulk mineraldeposit as a carrier and fully using the characteristic of easy reaction of Fe2O3 so as to achieve the CO removal purpose, such that the method is especially suitable for the removal operation of low-concentration carbon monoxide; and through the process steps provided by the invention, the removal operation of CO can be effectively realized.

Description

Technical field [0001] The present invention relates to the field of exhaust gas governance, and more particularly to a carbon monoxide treatment process. Background technique [0002] For the steel industry, in the exhaust gas produced, carbon monoxide accounts for a large part. In particular, in the pre-sintering stage, the proportion of carbon monoxide produced by the sintering process itself has roughly accounts for 20% of total carbon monoxide emissions, and carbon monoxide itself has certain toxicity. Once the production process is inhaled by workers or ordinary people, it will lead to poisoning. It is harm to life safety. [0003] In the prior art, carbon monoxide produced during the smelting process, in order to avoid adverse effects on the external environment, the re-combustion technique is usually employed, and the removal process of the absorbent, strong oxidant, and catalyst is used. Although the CO catalytic oxidation process reduces low concentration Co is more eff...
