Sewage sludge is primarily derived from waste water which also consists of a variety of other substances. Prior to drying the sludge, free water is removed by mechanical means such as a belt press or firame preas to achieve around 35--40% dry solids.Then the sludge pases to the Rotary Dryer for removal of remaining water to achieve around 85% dry solids.
Sludge dryer widely used for drying sludge, sewage sludge, textile sludge, municipal sludge, mineral slag,etc.
The sludge drying system includes: heat source, dewatering machine, drying equipment, conveying equipment, dust removal and deodorization equipment.
Heat source ①: Adopt natural gas combustion, plus heat storage type to improve the combustion efficiency of natural gas.
Heat source ②: Use biomass pellets, wood chips, branches, straw, coal, etc. as fuel.
The working principle of the drying area: Patented products, scattered drum dryers are used. There is a high-speed dispersing shaft inside the dryer to disperse the viscous sludge, solve the problem of sludge viscosity, and also improve the heat exchange efficiency. Set one, two, three, four, five six drying process working areas in the dryer, the final material moisture is less than 25%, complete the entire drying process, discharged from the dryer, and enter the next process.
