Continuous sludge hydro-thermal treatment reaction kettle device

The invention provides a continuous sludge hydro-thermal treatment reaction kettle device which mainly comprises a kettle body, a kettle cover, an inner guide cylinder, a stirrer and a sludge storage tank, wherein a water outlet is formed in the kettle cover; a sludge inlet, a steam inlet and an oxidant inlet are formed in the upper cover of the inner guide cylinder and are connected with the inner guide cylinder through the kettle cover; the stirrer is positioned in the center of the kettle cover and the inner guide cylinder; the bottom of the sludge storage tank is a conical surface of 30-60 degrees; a sludge outlet is formed in the bottom of the sludge storage tank. Through gravity deposition, sludge subjected to hydro-thermal reaction can be maximally separated from water, and the content of solid granules in water can be reduced, so that the influence of the granules in the water to later processes, pipelines and equipment can be alleviated, and meanwhile the energy consumption can be reduced.
