What are the advantages of sludge rotary dryers?

The sludge rotary dryer is the most common sludge drying equipment, which effectively reduces the water content and volume of sludge due to its high moisture content and viscosity. It can dry sludge with a water content of 90% in one go to the finished product, and has the advantages of simple and convenient operation, strong processing capacity, and stable operation. So, what are the advantages of sludge rotary dryers?

Advantages of sludge rotary dryer

1. The sludge rotary dryer adopts advanced hot air circulation technology, which can quickly dry the sludge in a short period of time. This technology can not only improve production efficiency, but also reduce energy consumption, greatly reducing the cost of sludge drying.

2. The sludge rotary dryer equipment has excellent drying effect. By precisely controlling the temperature and humidity of the hot air, the sludge can be evenly dried, avoiding excessive drying or moisture.

3. The sludge rotary dryer adopts multi-stage purification and dust removal equipment to reduce environmental pollution during equipment use.

4. Flexible selection of heat sources: Multiple heat sources can be used, such as natural gas, fuel oil, coal, steam, biomass fuel, process waste heat and flue gas, etc., making it convenient for enterprises to choose according to their own conditions.

5. This equipment adopts a combined self-cleaning device, greatly expanding the application range of single channel dryers. It can not only dry various types of sludge, but also dry various high viscosity materials.   

6. The structure of the sludge rotary dryer is reasonable and easy to operate. By using an automatic control device, the entire drying process can be automatically completed by adjusting the time through the control panel.

Working process of sludge rotary dryer

The sludge dryer is specifically designed to treat sludge with high moisture content, high viscosity, high water holding capacity, low calorific value, and other properties. The sludge dryer is mainly composed of a rotating body, a material lifting plate, a transmission device, a support device, and a sealing ring. The new material lifting plate has multiple functions such as guidance, diversion, and lifting, which can evenly distribute the material in the radial section of the dryer on the entire surface, forming a thin, uniform, and complete material curtain that fully contacts with the hot air flow, thereby achieving the goal of fully utilizing thermal energy.

In short, the sludge dryer equipment has important application value in the sludge treatment process due to its high efficiency, energy saving, excellent drying effect, and simple and safe operation.
