With the country’s strict requirements on the emission of air pollutants from power plants, the existing desulfurization and dust removal facilities can no longer meet the current standards. If the emissions cannot meet the standards, they will be in danger of being shut down, which will have an adverse impact on the enterprise. Therefore It is necessary to research and apply environmental protection equipment technology. Here, the editor recommends polytetrafluoroethylene dust removal membrane.
The grease content, CODcr and BOD5 and other pollution indicators in the degreasing waste liquid are very high. Treatment methods include acid extraction, centrifugal separation or solvent extraction. The acid extraction method is widely used. H2SO4 is added to adjust the pH value to 3-4 to break the emulsification. Steam is added and salt is stirred, and the oil is left to stand for 2-3 hours at 40-60 t. The oil gradually floats up to form a grease layer. The oil recovery can reach 95%, and the CODcr can be removed by more than 90%.
Polytetrafluoroethylene dust removal membrane is a three-dimensional mesh structure with no through holes. The porosity and pore size distribution are important indicators for measuring PTFE membrane. The porosity of ptfe liquid filtration membrane is generally between 80% and 95%. A high opening rate will increase ventilation; a concentrated pore size distribution indicates that the membrane pore size is uniform. It also has good filterability for special gases with high temperature, high humidity, high corrosion and organic liquids. With its special production process, the company can control different pore sizes for different materials to achieve high-efficiency filtration.
