Exhaust gas purification projects in the metal industry

>>Case Introduction

Case selection

The metal products industry includes structural metal products, metal tools, containers and metal packaging containers, stainless steel and similar daily metal products. With the progress of society and the development of science and technology, the use of metal products in industry, agriculture, and various areas of people's life has become more and more extensive, and it has also created greater and greater value for society. At the same time with these developments, the VOCs of the products in all steps of the metal products also increased sharply. VOCs are mainly formed from volatile substances in raw fuels such as coke and oily oxide scale, and are emitted as gas. VOCs emission reduction methods are divided into three types: source reduction, process control, and end governance. Source reduction is to reduce the introduction of oil from dust and crumbs, and it is the best choice to suppress the production of VOCs during the sintering process; process control is to re-introduce part of the hot exhaust gas of the sintering trolley into the sintering material layer for recycling. It is decomposed when it passes through the sintered zone above 1 300 ℃; the terminal treatment mainly includes activated carbon method and combustion method. Therefore, according to the actual situation of the company, we carry out a complete set of exhaust gas purification solutions, and use a combination of multiple purification methods to achieve a standard of high purification.
