The invention discloses a system device for supplying high-temperature clean hot air. The device comprises an outer frame (1), a high-temperature heat exchange chamber (3) is formed in the lower portion of the outer frame (1), one end of the high-temperature heat exchange chamber (3) is connected with a combustor (4) or directly connected with a high-temperature smoke pipeline through a flange, the other end of the high-temperature heat exchange chamber (3) is connected with a primary air mixing chamber (15) which is connected with a secondary air mixing chamber (6) through a high-temperature corrugated heat exchange plate (5), and the secondary air mixing chamber (6) is connected with a top air box (11) through a low-temperature needle-like heat exchange plate (7). The system device has the advantages that by means of indirect heat exchange, structural compactness is achieved; different types of heat exchange components with different flow passages are adopted for a convection section, large heat exchange area in unit volume and high heat efficiency are achieved, high-temperature clean air at the temperature higher than 600 DEG C can be supplied, and safety and stability in operation under high-temperature operation conditions can be realized.
Description
technical field [0001] The invention relates to a hot air device for indirect heating of a fluid, in particular to a high-temperature hot air working condition where the gas heat exchange temperature exceeds 600°C, and is especially suitable for providing high-temperature air for combustion support and clean gas for drying and heating of materials. Background technique [0002] At present, the high-temperature hot air devices encountered in the steel heat treatment and mineral wool processing industries mostly use a combined heat exchange device with a radiation sleeve and a convective heat exchange component. The structure is mostly a straight-through mechanism, that is, the front end uses a radiation sleeve and the end uses a tube type The heat exchange components are bulky and occupy a large area, the air outlet temperature is low, the internal air distribution structure is unreasonable, and the local parts of the equipment are prone to overheating, especially the stress c...
