Abstract

The invention relates to a fume heat abstractor used in a drying device, which belongs to the field of heating supply equipment. The fume heat abstractor used in the drying device consists of a cylindrical heat abstraction smoke box and an exhaust smoke device, wherein, the cylindrical heat abstraction smoke box consists of a first level heat abstraction smoke box and a second level heat abstraction smoke box. The first level heat abstraction smoke box is communicated with a smoke inlet pipe, and the smoke inlet pipe is communicated with the cylindrical first level heat abstraction smoke box along the direction of the tangent of the cylindrical first level heat abstraction smoke box; and the second level heat abstraction smoke box is communicated with a exhaust smoke pipe. The smoke inletpipe of the first level heat abstraction smoke box is communicated with the first level heat abstraction smoke box tangentially, the first level heat abstraction smoke box is communicated with the second level heat abstraction smoke box tangentially, the second level heat abstraction smoke box is communicated with a falling ash device tangentially. The fume enters into the first level heat abstraction smoke box tangentially and goes ahead helically along the wall of the first level heat abstraction smoke box. The detection time of the fume in the first level heat abstraction smoke box and thesecond level heat abstraction smoke box is comparatively long; therefore the heat abstraction utilization rate is high. The arrangement of a falling ash port and a falling ash device can clean away the soot effectively to lead the exhaust smoke to be clean and the effect of heat abstraction to be better.
