Problems solved by technology

[0005] However, in the actual application process, the existing carbon emission treatment equipment only treats the carbon monoxide and carbon dioxide in the flue gas and then emits them, resulting in heavy emission pollution, and does not recycle high-concentration carbon monoxide, resulting in waste of carbon monoxide , and the exhausted flue gas contains a large amount of carbon monoxide, which further causes serious carbon monoxide pollution. Therefore, we propose a steelmaking equipment based on low carbon emission for steelmaking

Embodiment 1

[0032] see Figure 1-9 , the present invention provides a kind of technical scheme:

[0033] A low-carbon emission steelmaking equipment for steelmaking. In this solution, a smoking port 5 is installed above the converter 1, so that the flue gas generated by the converter 1 can be absorbed by the smoking port 5, and the smoking port 5 passes through the flue gas cooling pipe. 6 and the flue gas dedusting box 7 are hollowly connected, so that the flue gas discharged from the converter 1 will flow into the flue gas dedusting box 7 through the flue gas cooling pipe 6. It takes a certain amount of time to cool the flue gas when it flows through the flue gas cooling pipe 6;

[0034] After the flue gas enters the flue gas dust removal box 7, the electromagnetic valve installed in the flue gas cooling pipe 6 seals the flue gas dust removal box 7, so that the dust removal equipment installed in the flue gas dust removal box 7 can remove the smoke air for dust removal;

[0035] After ...

Embodiment 2

[0040] see Figure 1-9 , on the basis of Embodiment 1, the present invention provides a technical scheme:

[0041] A low-carbon emission steelmaking equipment for steelmaking, the carbon dioxide treatment equipment 2 includes a lower treatment box 201 for flue gas filtration and an upper treatment box 206 for flue gas treatment. When the flue gas passes through the carbon dioxide discharge pipe 19 from After the air inlet below the lower treatment box 201 enters, three groups of installation racks 202 are fixedly connected to the inner wall of the lower treatment box 201 and are vertically distributed at equal distances. 203 can adsorb carbon dioxide in flue gas;

[0042] The filtering mechanism 203 is a porous material, and the filtering mechanism 203 is a combination of any two or more adsorbents in materials such as molecular sieve, activated carbon, silica gel and activated alumina, thereby improving the absorption effect of carbon dioxide;

[0043] And the side wall of ...

Embodiment 3

[0048] see Figure 1-9 , on the basis of embodiment two, the present invention provides a kind of technical scheme:

[0049] A low-carbon emission steelmaking equipment for steelmaking, the surface of the lower treatment box 201 is fixedly connected with the upper treatment box 206 through the installation platform 204, and the lower treatment box 201 and the upper treatment box 206 are connected through communication The pipe 205 is hollowly connected, and a solenoid valve is installed inside the communication pipe 205, so that the lower processing box 201 and the upper processing box 206 can be connected or separated;

[0050] After the flue gas in the lower treatment box 201 is filtered through multiple cycles, it is discharged into the upper treatment box 206 through the communication pipe 205. At the same time, the surface of the upper treatment box 206 is equipped with a chemical spraying mechanism 4, and the chemical spraying mechanism 4 is installed on the surface of t...

Abstract

The invention discloses low-content carbon emission steelmaking equipment based on steelmaking in the technical field of carbon emission treatment, and the low-content carbon emission steelmaking equipment comprises a converter, a flue gas dust removal box body, a flue gas component detection instrument, electrostatic dust removal equipment, an igniter and a combustion-supporting air supplementing mechanism. After completion, carbon monoxide and carbon dioxide are separated, meanwhile, high-concentration carbon monoxide is recycled, resources are saved, and energy-saving production is achieved; combustion-supporting air is added into flue gas containing a large amount of carbon dioxide and part of low-concentration carbon monoxide to be mixed, so that the low-concentration carbon monoxide can be sufficiently combusted to be converted into carbon dioxide, and emission pollution of carbon monoxide is further reduced; meanwhile, carbon dioxide is circularly filtered for multiple times, the concentration of carbon dioxide is reduced as much as possible, and a chemical reagent is sprayed to react with carbon dioxide in smoke dust to produce compounds, so that the content of carbon dioxide in smoke is reduced as much as possible, and low-carbon emission is realized.

Description

technical field [0001] The invention relates to the technical field of carbon emission treatment, in particular to a steelmaking equipment based on low-content carbon emission for steelmaking. Background technique [0002] Industrial waste gas refers to the general term for various pollutant-containing gases discharged into the air generated during the fuel combustion and production process in the factory area of ​​the enterprise. These exhaust gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (fog), lead and mercury, beryllium compounds, soot and productive dust, which are discharged into the atmosphere and pollute the air. These substances enter the human body through the respiratory tract through different channels, some directly cause harm, and some have accumulative effects, which will more seriously endanger human health, and different substances will have different ...
