Description

Technical Field

[0002] In the production process of modern integrated steel enterprises, the transportation of molten iron between the ironmaking and steelmaking processes is a crucial link in the technological connection. Currently, the industry commonly uses internal combustion engine-powered molten iron dispatching cars as the main transportation equipment. However, this equipment has revealed significant environmental defects and technical bottlenecks during long-term operation.

[0003] Traditional internal combustion engine dispatching vehicles use diesel engines as their power source and are required to continuously perform heavy-load transportation operations in actual operation. During the energy conversion process, complex pollutants are generated, including gaseous pollutants such as carbon monoxide, carbon dioxide, nitrogen oxides, and sulfur oxides, as well as toxic organic compounds such as polycyclic aromatic hydrocarbons and aldehydes, and solid particulate matter such as PM2.5 / PM10. These pollutants not only worsen the air quality in the plant area but also harm the environment. Existing technological improvements mostly focus on optimizing the exhaust aftertreatment system, such as adding DPF particulate filters or SCR catalytic reduction devices. However, these improvements have high equipment modification costs and require more frequent cleaning / replacement of filters, failing to fundamentally solve the problem of an unreasonable energy structure.
