SHAFT COOLER FOR DRY EXTINCTION OF COKE

摘要

According to the invention the annular inner lining work (11, 11a), situated above the openings of the gas uptake (19) is made as an independent body and suspended on the upper edge of the masonry jacket (5) by means of tubular anchorings (12, 12a). The stress due to the weight is transmitted from the anchorings (12, 12a) to the supports which bear to the upper edge of the jacket (5). The anchorings (12, 12a) may be located inside or outside the annular work (11, 11a). If they are arranged inside, a coolant is circulated through those tubular anchorings (12). The outer anchorings (12a) are conveniently embodied by parallel tubes which are connected throughout their length by struts so as to form a closed steel ring. Owing to the presence of the annular tubes (33, 34) welded to the upper and lower ends, the steel ring forms at the same time a heat exchanger and is connected in the evaporation section of the waste-heat boiler of the shaft cooler. Such arrangement of the annular work has the advantage amongst other things to suppress the support rolls which where heretofore necessary and very sensitive to perturbations in the region of the uptake openings (19). On the lower edge of the annular work (11, 11a), only bearing struts (18) are provided, which struts are radially arranged and spaced apart while defining the uptake openings (19); the inlets of the uptake openings (19) are thus substantially located in the plane or above the lower edge of the annular work (11, 11a).
