CDI’s S-Cooler of the 4th Generation has run successfully
Release Time：04/08/2010
Recently, S-Cooler of the 4th Generation developed by CDI with independent intellectual property right has run successfully at Yunnan Zhuangshan Industrial Co., Ltd. and all the figures have reached and even exceeded the design.
The S-Cooler pushes materials in a totally different way compared with other cooler of the 4th Generation. The unique movement of clinker works as blending and results in better cooling and then a higher heat exchange efficiency. The equipment is designed with module structure and there is no moving mechanism between the modules. Each standard module is composed of grate bed frame, low-resistance no-leakage fixed grate plate, sweeping conveying device (Patent Right No.: ZL200820115279.8), automatic flow regulator (Patent Right No.: ZL200820176603.7) and driving device, and the grate bed is supplied with air by air chamber. Materials are pushed from one end to the other by the reciprocating sweeping of the scrapers. Cooling air entering into the air chamber provides constant cooling to the materials via automatic flow regulator and grate plate. The automatic flow regulator will automatically adjust flow of the cooling air in line with materials’ resistances to prevent short circuit of the cooling air and then achieve equilibrium of air supply and higher cooling efficiency. As for the specially-designed S grate bed, the even seam ensures the cooling effect on materials while at the same time prevents materials going into the air chamber, which makes it possible to realize no materials leakage. Besides, since there is no glide between the grate plate and the materials in contact with the plate, the grate plate suffers no abrasion and therefore replacement of grate plate is unneeded. As compared with the movable grate plate and its frame of the 3rd Generation, the scrapers are much lighter and as a result less power is consumed at materials pushing.
The S-Cooler excels the grate cooler of the 3rd Generation in higher output of unit grate area, less cooling air for unit clinker, higher heat exchange efficiency, lower temperature of clinker at outlet of the cooler, less power consumption for unit clinker, higher utilization efficiency of heat energy, less civil costs for the system, and better technical indexes.
