lntroduction

　　Our company has specially developed and designed sludge drying equipment for materials like sludge,which has high moisture content,viscosity,and low calorific value.We has optimized the internal design of the dryer,which effectively avoids the phenomenon of sticking and over-drying of sludge in the dryer.In addition,the sludge dryer,compared with similar drying equipment,also has a smooth operation,easy to operate,fewer faults,low maintenance costs,low power consumption.The sludge dryer system can be applied to the drying of activated sludge,sewage sludge,petrochemical sludge,papermaking sludge,printing and dyeing sludge,tanning sludge,electroplating sludge,municipal sludge,biological fermentation sludge,etc.In addition,it is also applied to coal sludge drying,coal slurry drying,etc.

System

The main equipment of the sludge dryer include the induced draft fan, disintegration device, belt feeder, feeding machine, rotary drum, heat source, etc., which are divided into the material guiding area, cleaning area, inclined lifting plate area, and discharge area. Firstly, high moisture sludge is dewatered by the dehudrator machine, then transported to the rotary drum dryer by the belt conveyor, where it fully contact of the hot air, because of the inclination of drum dryer, material with hot air moves to the end of dryer. After drying, most of the dry material will be discharged through the belt conveyor, the left material will go into the cyclone dust collector, where the dust will be collected, with the function of induced draft fan, the left material will discharged through the conveyor.

Advantage

1. More energy-saving The sludge dryer uses a new type of transmission device, which can save 20% more coal compared to conventional dryers, allowing users to save more on operating costs and bring greater economic benefits. 2. Better dust removal effect The sludge dryer is more environmentally friendly, with dust removal effects that meet national environmental protection standards, reducing pollution and effectively protecting the environment. 3. More reasonable structure All components of the sludge dryer have undergone strict technical analysis, resulting in a more rational and efficient structure, with smoother operation. 4.Longer service life The wear-resistant parts of the equipment are made from new wear-resistant materials, significantly reducing wear during operation and extending the service life.
