<p>PCT No. PCT/DK84/00029 Sec. 371 Date Dec. 28, 1984 Sec. 102(e) Date Dec. 28, 1984 PCT Filed Apr. 12, 1984 PCT Pub. No. WO84/04471 PCT Pub. Date Nov. 22, 1984.In a cyclone for the cleaning of hot gases, the center-pipe (1) is produced of curved outer and inner elements (7, 8) which are made of fireproof material. The outer and inner elements (7, 8) are suspended in a self-supporting construction in upper end elements (2), and the lower edge of the center-pipe (1) is provided with lower end elements (14), in that the individual elements are suspended within each other by means of projections (9, 9), and the upper end elements (2) are suspended in a supporting structure (16) by means of anchoring devices (13) which cooperate with grooves in the upper end elements (2). There is hereby achieved a center-pipe (1) which is capable of withstanding high temperatures, and which can therefore be used in cyclones for the cleaning of hot gases. Since the center-pipe is built up of a large number of elements (7, 8, 2, 14), it can be expedient for it to be assembled during the building of the actual cyclone, and thus it becomes much easier and cheaper both to produce and to transport the individual elements.</p> |
