| 摘要 |
The present invention relates to a double cylinder type air cooling furnace, comprising: an air inlet formed in a lower portion; an exhaust gas outlet formed in an upper portion; a cylindrical inner container and a cylindrical outer container; and a grate formed in the lower portion of the inner container. The double cylinder type air cooling furnace with a reduced vortex comprises: a gradient unit (130) formed between upper ends of the cylindrical outer container (110) and the cylindrical inner container (120) and the exhaust gas outlet (160); and an inner container inlet (140) formed in an upper portion of the gradient unit (130) of the inner container (120) to enable air injected to a lower air inlet (150) to be lifted while rotating between the outer container (110) and the inner container (120) to be smoothly introduced into the inner container. |
