COOLING APPARATUS FOR AXIS OF SCREW CONVEYER OF CARBONIZATION FURNACE OF WOOD CHIP

摘要

The present invention relates to a cooling device for a screw conveyor shaft of a waste wood carbonization furnace. In the screw conveyor (2) which stirs and moves the waste wood of the carbonization furnace (1), the shaft (2x) of the tubular screw combier (2) A pair of water pipes 2a, 2a ', 2b, and 2b' are formed to protrude inward in the radial direction of the shaft 2x at both ends and the sealing cover 3 is not leaked around the water pipes. Not to be installed. When the cooling water w is supplied to the one side sealing cover 3A and the water supply pipes 2a and 2a 'by the water supply pipe 4, the water supply pipes 2a and 2a' protrude inwardly of the shaft 2x. Water level of the cooling water is maintained at the height of 2b 'and is circulated to the return pipe 4a through the other water pipes 2b and 2b' and the sealing cover 3B, Prevents deformation of the shaft 2x. Water vapor generated in the internal space (a) of the shaft (2x) passes through the sealing cover (3B) through the water supply pipe (2b) or (2b ') on the opposite side, through the steam pipe (4b), and inside the carbonization furnace (1). To be supplied.
