Problems solved by technology
[0005] However, although the existing louvered drum slag cooler has improved cooling capacity, the heat exchange area has not been fundamentally increased, and the space inside the inner cylinder has not been utilized at all.
Since only the interlayer formed by the inner and outer cylinders can pass through the cooling medium, it is only suitable for water cooling to produce hot water, not suitable for air cooling to produce hot air.
Most of the existing air-cooled slag coolers use cooling air to directly contact high-temperature materials for cooling, and the hot air generated is dust-laden hot air, which cannot be used for drying and other purposes

Embodiment Construction
[0020] The present invention includes a roller with an interlayer composed of an inner cylinder and an outer cylinder, a lifting plate 4, a cooling pipe 1, and a fin 5. Between the inner cylinder 3 and the outer cylinder 2 is the interlayer of the roller, the lifting plate 4 is arranged on the inner wall of the inner cylinder 3, and a certain number of cooling pipes 1 with fins 5 on the outer wall are arranged in the inner cylinder 3. The roller is placed horizontally or at a certain angle, supported by a supporting device, and driven by a power device to rotate. Cooling air is passed through the cooling pipe 1 and the interlayer, and the interlayer spiral insert 8 is arranged in the interlayer. The cooling pipe 1 and the star insert 7 or spiral insert 6 are arranged to increase the stroke of the cooling air, increase the cooling time and strengthen the heat exchange, to achieve better The cooling effect. When the drum rotates, the material enters from the inlet in the middle,...

The invention discloses a cooling structure of a high-temperature material waste heat recycling device, comprising a rotary drum, a lifter, a cooling pipe and fins, wherein the rotary drum consists of an inner drum and an outer drum and is provided with an interlayer. The lifter is arranged on the inner wall of the inner drum, the fins are arranged on the outer wall of the cooling pipe, the fans and the lifter are straight plates or are bent at the lower parts, the bending direction of the fans and the lifter is opposite to the rotating direction of the cooling pipe, the cooling pipe is in a circular pipe structure and is internally provided with a star plugin or spiral plugin, the interlayer is internally provided with an interlayer spiral plugin, the interlayer and the cooling pipe are both used for introducing cooling air, and the plugins are removed if water cooling is adopted. The high-temperature material is in repeated contact with the inner drum with the lifter and the cooling pipe with the fins, thus, the cooling time is prolonged; the interlayer and the cooling pipe can be used for simultaneously introducing cooling medium, thus, the cooling area is greatly increased, the cooling capacity is enhanced, waste heat of high-temperature material is favorably recycled, and meanwhile, the length of a cooler is reduced.
Description
technical field [0001] The invention belongs to the cooling structure of a high-temperature material waste heat recovery device, which is widely used in metallurgy, electric power, chemical industry, energy, building materials and other industries. Background technique [0002] At present, domestic slag coolers are divided into water-cooled, air-cooled and air-water combined slag coolers from the cooling medium. Feng-water combined slag coolers currently have a large stock share in large circulating fluidized bed boilers. [0003] Among the existing slag cooling machines, there is a louver drum slag cooling machine, whose Chinese patent publication number is ZL200820061864.4, and the disclosure date is January 14, 2009, and the patent name is a lifting plate drum slag cooling device. The lifting plate type drum slag cooling machine is also called the louver drum cooling slag machine. There are several lifting plates arranged on the inner wall of the inner cylinder. The top ...
