A kind of sludge carbonization method
ActiveCN112520968BEasy to operateThe production process is compactSludge treatment by de-watering/drying/thickeningSludge treatment by thermal conditioningCombustionSludge
The application discloses a sludge carbonization method, which includes the following steps: 1) first dehydration: use hot air to reduce the water content of sludge by 10-20%; 2) low-temperature inactivation: the sludge after the first dehydration is ‑300°C for the second dehydration and inactivation, so that the water content of the sludge after the second dehydration is less than 10%; 3) Oxygen-controlled combustion: Under the condition of oxygen control, the sludge after the second dehydration is at a temperature lower than 600°C 4) Oxygen-deficient stabilization: send the product obtained from the combustion to the anoxic link for carbonization and stabilization, lower the temperature to below 40°C, and discharge to obtain the final product. The sludge carbonization method provided by this application has a small investment and can realize "sludge burning sludge", while retaining part of the calorific value, making the sludge carbonization stable, increasing added value, turning waste into treasure, and thoroughly disposing of sludge , No pollution, use the truck to carry the sludge, improve work efficiency.
