Regeneration furnace with combined cooling structure

The invention discloses a regeneration furnace with a combined cooling structure. The regeneration furnace comprises a plurality of spiral conveyors. Packing auger shafts of the spiral conveyors are hollow shafts in which cooling media can circulate. The outer walls of the spiral conveyors are further sleeved with cooling casing pipes used for circulation of the cooling media. The manner that the outer walls of the spiral conveyors are sleeved with the cooling casing pipes and combination of the packing auger hollow shafts is adopted for cooling is adopted, the cooling media exchange heat with heat transmitted to the shafts through pipe interior powder activated carbon through the packing auger hollow shafts, the heat on the shafts is constantly brought away, and the purpose of rapidly cooling the powder activated carbon can be achieved. 本发明公开了种具有组合降温结构的再生炉，包括若干螺旋输送机，螺旋输送机的绞龙轴为能流通冷却介质的中空轴；螺旋输送机外壁上还套设有冷却套管，用于冷却介质的流通。本发明采用螺旋输送机外壁上套设冷却套管和绞龙中空轴结合降温的方式，冷却介质通过绞龙中空轴与管内粉末活性炭传递到该轴上的热量形成热交换，不断的带走轴上的热量，能实现快速冷却粉末活性炭的目的。
