Hubei develops PM2.5 control technology for iron and steel kiln

The Ministry of Science and Technology and Hubei China Steel Tiancheng Environmental Protection Technology Co., Ltd. signed a mission statement recently to entrust China Steel Tiancheng to undertake the "12th Five-Year Plan" resource and environment technology field "iron and steel furnace dust PM2.5 control technology and equipment" Question. The project was led by China Steel Tiancheng, and Northeast China University, Tsinghua University, and Panzhihua Iron and Steel Group Chengdu Steel Vanadium Co., Ltd. participated in the implementation.

The main research purpose of this 863 project is to research and develop high-efficiency control technology and equipment for PM2.5 fumes in China's steel furnaces, improve the high-efficiency trapping technology of PM2.5 in iron and steel furnaces, and form integrated technologies with independent intellectual property rights. Complete sets of equipment, fine filter materials and intelligent control technologies to control the fine particulate emissions and total dust emissions from the kilns in the steel industry, and to improve urban and regional air quality.

In recent years, PM2.5 fine particle pollution has brought a great impact on China’s air quality, national living standards, and health and safety. Together with air pollutants such as NO x, nitrogen oxides, etc., it will cause hazy weather. . PM2.5 fine particulate matter is mainly formed in the exhaust gas and tail gas produced in the smelting of steel, coal mines, power generation, and automobiles, and is especially led by heavy industry. During the "Twelfth Five-Year Plan" period, the Ministry of Science and Technology established the "863 Project" in the above-mentioned industrial fields, and the PM2.5 treatment in the field of metallurgical kiln undertaken by China Steel Tiancheng is due to the large amount of smoke, fine dust, and high temperature of the flue gas. , is one of the more difficult topics.

"As the country attaches greater importance to environmental protection and the improvement of air emission standards, metallurgical enterprises will face a new round of environmental protection and technological upgrading. In the next decade, the steel industry's demand for dust removal equipment will reach approximately 4 billion yuan per year." Li Ning, head of China Steel Tiancheng Technology Center, said.
