Sludge drying?
Thread Content
Hello everyone. Recently I have been looking for equipment for drying sludge, and I came across a technology for low-temperature sludge drying that uses a heat pump as a heat source; the drying temperature in this process is only 70 degrees. The moisture produced during drying is condensed and recovered. I was wondering if anyone has used this product and what its performance is like. Experts, could you recommend any other equipment options that represent good process equipment options in terms of process efficiency, energy consumption, and the absence of secondary pollution? 20 tons of sludge containing 80% water are produced daily.
Our factory cannot achieve such results. . . . . . . . . . . . .
How about trying some sludge dewatering agents?
Sludge drying is carried out using sunlight and solar energy; in winter, geothermal heating is employed. The investment is estimated to be around 1 million.
Drying is carried out using hollow paddles, with steam and heat transfer oil as the heat sources; the investment required is around 400,000 yuan, although the operating costs are higher compared to drying by air exposure.
We also produce this type of equipment; the drying temperature is 55 degrees, and fresh products hardly produce any odor. 70 degrees will definitely be extremely smelly.
