Efficient sludge thin-layer drying equipment

1. Product Features

Efficient sludge thin-layer drying equipmentIt can adapt to different sludge treatment needs through independent design, using inert carrier gas in a closed system to avoid dust and odor overflow. Its unit heat exchange area water evaporation rate (positively correlated with drying efficiency) is 0.030t/m²h， The host occupies an area of 33.5m²The moisture content of the sludge can be between 30% and 35%, with technical characteristics such as high drying efficiency, small footprint, simple operation, safety and environmental protection, and flexible and adjustable moisture content of the sludge. At the same time, it has advantages such as "imported product quality, domestic equipment price, Shanghai water brand, operation and maintenance experience, and full life cycle service".

4. Product Application Cases

The Shidongkou old line renovation and incineration sludge treatment and disposal project is a maintenance and renovation project for the Shidongkou old line sludge treatment. Its main solution is the problem of insufficient drying capacity of the old line incinerator. Due to the small size of the old line, it can also serve as a test base for the localization of sludge drying and incineration equipment. The scale of the old line incinerator is around 20tDS/d, so it is necessary to equip corresponding drying equipment. Considering the many advantages of thin-layer drying equipment, the scale of the old line incinerator is around 20tDS/d, so it is necessary to equip corresponding drying equipmentEfficient sludge thin-layer drying equipmentDue to the many advantages of the device and the current situation of independent research and development, it is proposed to adopt the self-developed 50m²The domestically produced thin-layer drying machine with heat exchange area serves as the main equipment for the drying process. After the renovation of the project, the dehydrated sludge with a moisture content of 80% (78%~82%) is transported by dump trucks to the sludge treatment plant. After passing through the sludge receiving and storage system, the dehydrated sludge is pumped to the sludge drying system. After treatment by the drying system, the average moisture content is reduced to 30% (adjustable range of 30%~35%), and the resulting dry sludge is lifted by a bucket elevator to the old line incinerator for incineration. The project has undergone preliminary operational testing, and overall the equipment is running stably. On the basis of this demonstration project in the future, it can not only be used as a product for sludge drying in medium-sized sewage plants, but also provide maintenance services for existing thin-layer machines with independent advantages such as localization experience and price.
