RADIAL-FLOW-TYPE HYDROTHERMAL REACTOR FOR SLUDGE PYROHYDROLYSIS TREATMENT

摘要

The present invention relates to the field of sludge reduction treatment, and particularly, to a radial-flow-type hydrothermal reactor for sludge pyrohydrolysis treatment. An outer barrel and an inner barrel are sequentially embedded in a barrel body of the reactor in a sleeved manner, and a flow guiding barrel is disposed between the outer barrel and the inner barrel; a flow guiding pipe is disposed on the sidewall of the flow guiding barrel; a stirrer is mounted in the inner barrel, so that the viscosity of sludge is decreased after the sludge in the inner barrel reaches a reaction parameter, and the flowability of the sludge is good. Because an inlet pipeline is disposed below the inner barrel, the sludge enters the inner barrel from the bottom of the inner barrel and flows out of the inner barrel from the top of the inner barrel; and because the diameter of the inner barrel is not large, the heating time can be ensured. The height-to-diameter ratio of the radial-flow-type hydrothermal reactor is very small and the sludge has good flowability after being heated, so that the sludge in large space of the outer barrel flows outward in a radial manner; and the flow rate of the sludge is decreased along with the enlargement of the flowing radius while the reaction continuously proceeds, so that the reaction time is ensured within the limited space of the reactor. In this manner, the radial-flow-type hydrothermal reactor can continuously run and has a compact structure.
