Technical introduction

 Active sludge is a general name for microbial community and organic and inorganic matters. Active sludge is discovered by British Clark and Gad IN 1912. Active sludge can be divided into aerobic active sludge and anaerobic particle sludge. Active sludge is mainly used to disposing sewage and waste water. Active sludge disposal is a method which uses micro floes that grows in a suspension state. 


1. High thermal efficiency and low drying cost;
 New internal structure can strengthen materials cleaning and thermal conduction. It can also eliminate wall stickiness. It can better adapt to various materials and moisture. Therefore, heat exchange area and drying efficiency can be expanded. Relevant parameters can be changed according to types of materials. The whole drying system is controlled by variable frequency. Thus, materials can get full heat exchange. Compared with traditional dryers, the coal and power consumption can be reduced by 20% to 25%. The whole drying process is carried out in a totally closed environment, which can prevent the entrance of cold air and improve utilization rate. The good quality of final products can be guaranteed.
2. Reliably running and good stability
New feeding and discharging device can avoid materials blockage, in-consistence, nonuniform and back-mixing. This dryer adopts self-aligning type tug device which can ensure that linear touch between tug and roller ring. Thus, abrasion and power consumption can be greatly reduced. The running of drum is more stable and reliable.
3. Wide range of heat source and no pollution to environment
It can adopt coal, oil, natural gas and liquefying gas as its heat sources. Heat source can be decided according to specific requirements and local situations in order to improve economic effects. Coal gasifier and biomass combustion furnace work as heat carriers. The whole process is energy-saving , safe and clean. Materials holds no pollution after drying disposal. The heat efficiency is 30% higher than combustion furnace. Only one operator is needed in the process. it is not necessary to charge coal circularly. The machine can be stopped at any time.
4. High automation level and safe production with concurrent supervision
The whole system is controlled by PLC automatically. The system contains advanced monitoring equipment: temperature monitoring, pressure monitoring, temperature adjustment (can be adjusted according to specific requirements), automatic alarm system and automatic protection function . TV supervision system consists of supervising and controlling production situation and production post in order for better drying effect.

Working principle

Active drying sludge is mainly composed of heat source, loader, feeder, rotary drum, crushing device, unloader, induced draft fan, discharger and electricity distributing cabinet. After dehydration, materials are sent to dryer. With the stirring of copy plates in rotary drum, materials will spread evenly in the dryer and get full contact with hot air, which speeds up the heat and media transmission. In the drying process, under the function of slant copy plates and hot media, materials are sent to star discharger at the other end of dryer as finished products.
