Patent ID: 7513061

Claim:
A sludge dehydrating processor for converting sludge including an organic substance into resources of low water content, the processor comprising a heating treatment zone for heating the sludge fed while flowing as an object to be treated to a sterilizing treatment temperature and a dehydrating treatment/retrieving zone for carrying out treatment of separating water from the high-temperature object to be treated which has passed through the heating treatment zone and retrieval of treated object which has been subjected to the treatment, wherein the heating treatment zone includes: a feed heating kiln body formed of at least one metal pipe in such a manner that a hollow portion of the metal pipe functions as a flow path for the object to be treated; a heating induction coil disposed to surround the kiln body to inductively heat the kiln body; and a high-frequency power supply unit for driving the coil and the dehydrating treatment/retrieving zone includes: a cylindrical dehydrating treatment chamber; at least one lead-in path for the object to be treated and provided on one end side of the treatment chamber; at least one gas jet nozzle provided on the one end side so as to produce a vortex air current for causing the led-in object to be treated to travel via a route spirally swirling along an inner peripheral surface of the treatment chamber and in such a manner that a substantial tangent direction of the gas jet nozzle is a jetting direction on the inner peripheral surface; a gas feed mechanism for the nozzle; a treated object discharge port provided to the other end side of the treatment chamber; treated object retrieving equipment following the discharge port; an exhaust port provided to the one end side; and a forced exhaust mechanism connected to the exhaust port.
