Industrial development and air pollution have become unavoidable topics in the social environment.

Many cities suffer from severe air sulfur dioxide pollution, and the energy consumption structure dominated by coal is an important reason for the increasingly serious sulfur dioxide pollution. Thermal power plants are the main consumers of coal, and their emissions of sulfur dioxide account for nearly half of the total emissions. Therefore, controlling sulfur dioxide pollution from coal-fired emissions is a key focus. Many places mainly use desulfurization equipment for desulfurization to reduce sulfur dioxide emissions. The investment demand for new desulfurization projects in the power industry is about high.

According to the total number of sintering machines in the steel industry, which is about a thousand, only a few have installed desulfurization devices. Among these few in-service desulfurization equipment, some cannot operate normally.
