Integrated Sludge Drying and Carbonization System

Process flow

Dryer: The sludge is broken into 1-5mm particles, and the sludge particles are directly dried by high-speed hot air. The drying temperature is 150 °C, and the water content of the discharge can reach 5%.

Carbonization furnace: The sludge is heated by spacers. In the anaerobic environment, the sludge is cracked in the range of 400-600 °C, and the produced combustible dry distillation gas such as H2, CO, oil and gas is burned back to provide heat for carbonization (except when starting, Carbonization does not require energy) and eventually produces carbonized products.

Dry carbonization integrated system: Carbonized high-temperature tail gas can be used for drying and utilization, reducing the energy consumption of drying, without the need for additional carbonized tail gas treatment system.

Solve the problem of adhesive phase

The unique pulverizing and stirring device inside the dryer rotates the sludge at high speed while drying the sludge in the cylinder, and thoroughly pulverizes the sludge into fine particles, which can solve the problem of sludge adhesive phase in the drying process;

Low operating costs, heat energy can be recycled

Carbonization by burning dry distillation gas without the need to provide additional fuel;

Sludge volume reduced by more than 85%

After the sludge is dried and charred, the final volume and total amount are reduced by more than 85%;

The product is harmless and has a wide range of uses.

The final product has a particle size of 1-5mm and is stable in nature. The heavy metal is solidified, which fundamentally solves the problem of heavy metals. The product can be used in the fields of soil improvement and deodorization adsorption.
