Embodiment 1

[0026] A sintering head flue gas whitening process, such as figure 1 As shown, it includes the primary cooling tower 11, the booster fan 12, the second cooling tower 13, the desulfurization tower 14, the flue gas condenser 15, the MGGH system 16, the chimney 17, and the flue gas connected to the flue gas condenser 15. The condensation tower 18 also includes a circulation system arranged between the MGGH system 16 and the second cooling tower 13 , and the circulation system communicates the second cooling tower 13 with the MGGH system 16 .

[0027] Such as figure 1 As shown, the primary cooling tower 11 adopts ND steel, and the second cooling tower 13 adopts fluoroplastics.

[0028] Such as figure 1 As shown, the circulation system is made of fluoroplastic.

[0029] Such as figure 1 , 2 As shown, the desulfurization tower 18 includes a desulfurization and denitrification pipe 181 arranged at the bottom and a redox chamber 182 arranged at the top, and the desulfurization an...

Abstract

The invention relates to a sintering machine head flue gas white smoke removing process. The process sequentially involves a primary cooling tower, a booster fan, a second cooling tower, a desulfurizing tower, a flue gas condenser, an MGGH system and a chimney, and further comprises a flue gas condensing tower communicated with the flue gas condenser, and further comprises a circulating system arranged between the MGGH system and the second cooling tower, and the second cooling tower is communicated with the MGGH system through the circulating system. The flue gas treated by the flue gas whitesmoke removing system not only recycles the waste heat of the flue gas, but also can effectively reduce pollutants in the discharged flue gas; the flue gas white smoke removing system not only eliminates visual pollution in the flue gas emission process, but also purifies flue gas, so that the content of pollutants in exhausted flue gas is lower; user requirements and economic benefits are comprehensively considered, the layout is more reasonable, and the setting is more flexible.

Description

technical field [0001] The invention relates to a flue gas whitening system, in particular to a sintering head flue gas whitening process. Background technique [0002] In the iron and steel industry or other industrial production, the flue gas produced by the combustion between raw materials and fuels contains a large amount of nitrogen oxides, sulfur dioxide and particulate matter, which has caused certain pollution to the atmosphere. In May 2018, China issued the "Work Plan for Ultra-Low Emission Transformation of Iron and Steel Enterprises (Draft for Comments)". The "Draft for Comment" clarified that iron and steel enterprises in various regions should carry out ultra-low emission transformation step by step. Under the condition of the standard oxygen content of 16%, the hourly average emission concentrations of particulate matter, sulfur dioxide, and nitrogen oxides are not higher than 10, 35, and 50㎎ / m3 respectively. The removal methods of sintering flue gas nitrogen ...
