Catalyst filtration, decarbonization filtration, high temperature filtration, high viscosity filtration, high corrosion filtration, automatic back blowing filtration
Catalysts and cracking agents used in refining and chemical units, as well as solid-phase catalyst production involved in petrochemical industry, belong to the field of high-tech content. These catalysts contain a variety of harmful heavy metals and produce a lot of dust in the production process.
Recently, due to the more stringent requirements of environmental protection, the dust particles discharged from the catalyst production unit are strictly monitored.
The production process of catalyst involves the dissolution and dispersion of metal salt, the loading and precipitation of carrier oxide, drying, calcination, decomposition, reduction, aging and other processes. The high efficiency gas-solid separation technology is adopted in the production process of these catalysts, which can not only recover the catalyst particles with high value, but also reduce the production environment atmosphere and exhaust catalyst particles content, which is of great significance to the health of production workers and environmental protection.
