Sludge dryers manufactured by Northeastern University Shenyang Yitong Science and Technology Co., Ltd. can directly dry high-viscosity and high-humidity materials, and can dry 80% moisture-containing dry powder with 80% moisture. The sludge drying system is operated with full negative pressure. It is equipped with a heat transfer device for direct heat transfer, convenient control of dry material moisture, low temperature mechanical equipment in the system, simple and reliable, and low failure rate.
The sludge drying equipment has the advantages of wide adaptability, low operating cost, no sludge nozzle clogging, flexible and adjustable system, simple operation and automatic system operation, and is suitable for sludge incineration, sludge agriculture reuse, production of building materials, Sludge non-agricultural use, sludge landfill, sludge and waste mixed treatment. Widely used in activated sludge, sewage sludge, petrochemical sludge, paper sludge, printing and dyeing sludge, tanning sludge, electroplating sludge, municipal sewage treatment plant sludge, bio-fermentation residue and other sludge and each The dregs and other high-humidity materials are dried.
Sludge drying is the use of a heat source to heat the dewatered sludge, further removing the capillary water from the sludge, and making the solids content of the sludge reach 70% to 90%. Drying process is more widely used or heat drying, all heat drying require a heat source. In addition to the dryer, the structure should also include sludge feeders, auxiliary heat sources, air supply systems, heat recovery devices, dust control, ash discharge, and control systems.
