| Abstract: |
| Emulsified sludge is a kind of sludge produced in the production process of metallurgy,petrochemical industry,coal chemical industry and other industries, which has been piled up for a long time. Because of the complex impurities and viscous physical properties, Solid-liquid separation becomes the difficulty of sludge treatment technology. A new solid-liquid separation equipment for emulsified sludge is proposed in this paper. Solid-liquid separation of sludge is realized by slurry and pressure extrusion，the moisture content of solid material separated by high extrusion pressure is less than 50%. At the same time, the emulsified membrane in the emulsified sludge is crushed by pressure extrusion, which realizes mechanical physical demulsification without chemical demulsification, reduces the addition of chemical components in the emulsified sludge.and simplifies the process. This technology has high practicability and innovation. |
