A spray slag cooling device for vertical moving bed gasification of rice hulls

Abstract

This utility model discloses a spray cooling device for vertical moving bed gasification of rice husks, including a processing plant and a conveyor belt for transporting rice husk waste, located on the upper right side of the processing plant. The conveyor belt is powered by an external power source. A slag collection box is located on the lower left side of the processing plant. A rotating rod can rotate on a water spray pipe, and the left end of the rotating rod is connected to the inner wall of the processing plant via a rotating bearing. Multiple fixed arms on the rotating rod connect to rotating vortex blades. Under the impact of high-pressure airflow and water flow, the rotating vortex blades drive the rotating rod to rotate, causing the rice husk waste falling from the conveyor belt to remain on the rotating vortex blades for a period of time, fully contacting the medium sprayed from the high-pressure water nozzles and high-pressure airflow nozzles. This design greatly improves the cooling effect, allowing the waste to be cooled more comprehensively and thoroughly, ensuring uniform cooling, avoiding local overheating or insufficient cooling, and facilitating subsequent treatment and utilization of the waste.
