Abstract
A radial flow hydrothermal reactor for a sludge thermal hydrolysis treatment is provided. An outer and an inner cylinder are successively sleeved in a cylindrical body of the reactor. A guiding cylinder is arranged between the outer and the inner cylinder. Guiding pipes are provided on the guiding cylinder. An agitator is arranged in the inner cylinder, so that sludge has low viscosity and good fluidity after reaching reaction parameters. Because an inlet pipe is arranged below the inner cylinder, the sludge enters the inner cylinder from bottom and flows out from top, and the inner cylinder has a diameter not large, which guarantees heating time. Because of a small height-to-diameter ratio of the reactor, the sludge after heating has the good fluidity, and flows outward radially in the outer cylinder. With an increased flowing radius, a flowing velocity decreases, and a hydrothermal reaction proceeds continuously, which guarantees reaction time.
