Directt rotary sludge dryer

Fluidized bed dryers for drying dewatered sewage sludge operate in a closed inert gas loop. The entire heat required to evapo - rate the water is fed to the dryer via heat exchangers, i.e. without any direct contact between the heat transfer medium and the product. The dewatered sewage sludge is pumped directly to the fluidized bed dryer

    Rotary drum dryers. Rotating drum – or rotary – dryers consist of a drum, several metres in length and ~2 m in diameter, which is inclined at 3–4 to the horizontal and rotates around its axis at a speed of 4-8 RPM. The drum is fitted with internal structures (fins, paddles or blades) which agitate and break up the sludge solids and help

    May 12, 2020 Flash dryers operate at a very short residence time. The sludge is dried using a rising hot air stream, flowing at 20–30 m/s, to both suspend and dry the particles. The dried product is separated using cyclones and/or bag filters. The dried sludge and exhaust gas temperatures are normally around 70 C (160 F) and 100–150 C respectively

    The rotary dryer can operate both in concurrent or countercurrent flow arrangement. Permissible velocities of gases inside the cylinder are selected as a function of specific gravity and particle size of the product to be dried. Direct Rotary Dryers can use as heating media: hot gases, for drying sand, clay and mineral and chemical products; hot air, produced by heat exchangers, for the drying of heat sensible
