Title:
MATERIAL HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/107663
Kind Code:
A1
Abstract:
A material heating device comprises a rotary kiln (1), a plurality of heat exchange tubes (2), a hot air hood (3), a high-temperature gas input mechanism (4), an exhaust collecting chamber (5), and an exhaust gas output pipeline (6), wherein, the rotary kiln (1) is provided with a feed end (7) and a discharge end (8), the heat exchange tubes (2) are provided in the rotary kiln (1), the hot air hood (3) is provided outside the rotary kiln (1), the air inlet end of the heat exchange tubes (2) is connected to the hot air hood (3), and the air outlet end of the heat exchange tubes is connected to the exhaust collecting chamber (5) that is connected to the exhaust output pipeline (6), the hot air hood (3) is in communication with the high-temperature gas input mechanism (4), and the cavity between the heat exchange tubes (2) and the insulation layer (13) of the rotary kiln (1) is a material channel. The heat exchange tubes (2) is directly in contact with the material, and most of the heat is directly transferred to the material through conduction and radiation with less heat loss. Meanwhile, the exhaust after heat exchange does not contact the coal gas generated by pyrolysis, and thus the produced coal gas has a high purity, a high heat value, and a high utility value.
