Technical introduction

There are a lot of microorganism in river and canal sludge. This problem is always neglected. Therefore, much damage is caused to human and environment. The amount of municipal sludge is getting more and more. The disposal and development of sludge becomes a problem which gets more and more attention. With the improvement of environmental protection and national economy, municipal sludge disposal gets greatly developed. Sludge dehydration makes agricultural utilization, fuel application, incineration and landfill possible. 

Advantages

1. large output and high thermal efficiency. Drying efficiency can reach 60% while drying unbound water. Strong drying intensity. Materials will disperse highly in airflow. All superficial area of materials is effective drying area. Coal consumption gets greatly reduced.
2. adopt computer to control the whole system; according to different drying requirements, different drying temperature and drying time can be designed in order to realize automatic drying. In this way, labor force and materials can be saved and working efficiency can be improved. It can be applied to many types of burners.
3. New internal structure can strengthen cleaning and heat conduction function. It can eliminate bond situation . It has stronger adaptability to materials’ moisture and stickiness. We adopt brand new type gears to replace traditional cast steel gear, which can not only save cost, but also reduce maintenance cost and drying time.
4. After adjustment of riding wheel, catch wheel will afford less pressure. In this way, the service life of riding wheel and catch wheel will be expanded. Production cost can be reduced and production effect can be improved. 

Working principle

1. New type municipal sludge dryer can dry the 90% moisture content to finished products one time. Aiming at the agglomeration feature of sludge in the drying process, we change the structural form of single-pass dryer. It adopts combined self-cleaning device. The application range of this dryer is greatly enlarged. It can not only applied to various sludge, but also can evaporate partial moisture content after preheating.
2. Through feeder, sludge enters material guide plate. With the rotation of drum, sludge is led to inclined materials lifting plate and is lifted to central place of drum. Then, a materials curtain is gradually formed. Hot air passes through materials. Then, sludge gets preheated and partial moisture content gets evaporated.
3. After scattering and movement of sludge to mobile grate type flange, materials will mix with preheated grates. Therefore, heat will be led to materials and majority of moisture content is evaporated. Meanwhile, flange will carry materials, then lift and scatter. These actions are repeated many times. There is a convection and heat exchange between materials and hot airflow.
4. Cleaning device which is buried in materials will slid along circular arc of lifting plate. Materials which stick on inner wall of lifting plate will be eliminated.
5. While cleaning device finishes the rotation of vertical line, it will also be dragged at the reverse side of lifting plate and clean materials which stick on wall of lifting plate. With continuous rotation of drum, moisture content gets evaporated and sludge gets further dried.
6. Meanwhile, clean device also works as breaking-up device. It improves drying speed. Finally, after dehydration, sludge becomes loose materials which will be discharged from outlet.
