| 摘要 |
The present invention relates to a radial multi-stage rotary cooling apparatus cooling a discharge gas, a solid product, or a liquid material at high temperature, wherein the discharge gas, the solid product, or the liquid material at high temperature is discharged from the carbonization or the incineration of activated carbon, sewage sludge, industrial materials, or food waste. The radial multi-stage rotary cooling apparatus according to the present invention comprises: an outer case module having an outer cell; an inner case module inserted into the outer cell; a twin-type rotary joint supplying a coolant, and discharging steam or hot water, wherein the inner case module includes: an inlet into which the product or the discharge gas at high temperature is injected; an outlet from which the cooled product or the cooled discharge gas is discharged; a central axis tube connected to the inlet and the outlet; multiple radial tubes arranged around the central axis tube, and communicating with the central axis tube; and coolant jackets arranged between partitions between the central axis tube and the radial tube. Therefore, manufacturing costs of the radial multi-stage rotary cooling apparatus can be reduced and the durability of the radial multi-stage rotary cooling apparatus can be improved, thereby largely improving the product competitiveness of the radial multi-stage rotary cooling apparatus. |
