Abstract

The present invention discloses a sludge pyrolysis and carbonization device with a function of efficient utilization of gaseous products and a method for using the same, and relates to the field of sludge treatment. The sludge pyrolysis and carbonization device with a function of efficient utilization of gaseous products comprises a pyrolysis and carbonization unit and a combustion and heating unit. The pyrolysis and carbonization unit comprises a drying chamber and a carbonization chamber, and the exteriors of the drying chamber and the carbonization chamber are both provided with a heat energy efficient utilization mechanism. The sludge pyrolysis and carbonization device with a function of efficient utilization of gaseous products achieves efficient heat utilization by directly passing the high-temperature flue gas in the combustion chamber into the heat energy efficient utilization mechanism for heat exchange, and then removing impurities and denitrifying the tail gas at the end. At the same time, the heat energy efficient utilization mechanism can extend the residence time of the high-temperature flue gas outside the drying chamber and the carbonization chamber, thereby improving the heat exchange rate and automatically cleaning the flue gas particulate matter therein.
