In China, traditional industrial dust removal methods mainly involve bag filters and electrostatic precipitators, which are all low-temperature dust removal technologies operating below 260°C. In other words, high-temperature gases must be cooled to below 260°C before filtration can take place. This filtration process results in significant waste of water resources and high-temperature thermal energy; the dust removal efficiency is low, it can cause secondary pollution, and it fails to meet **emission standards**. Is there such a process for dust removal and filtration while keeping the temperature at its original high level?
It seems there is such a technology, with industrial applications in the fields of coal chemical industry and electric arc furnaces
Could you provide a detailed introduction: handshake
Under high-temperature conditions, due to significant changes in viscosity, humidity drops sharply, and the agglomeration of fine particles is greatly reduced, making it more difficult to separate the particles. Engineering issues such as the material and structural design of equipment used at high temperatures, as well as thermal expansion, often affect the effective and proper operation of the equipment. Among various gas-solid separation technologies, the sintered porous metal filtration technique makes the most of the gas’s sensible heat and useful energy sources, while simplifying the process flow and reducing equipment costs. Furthermore, the sintered porous metal filtration technology offers significant advantages, including improved product purity, increased production volume, elimination of emission pollution (reducing or avoiding air pollution), protection of critical downstream equipment, as well as energy savings and cost reduction.
