Abstract

The invention relates to a rotary kiln barrel body surface waste heat utilization device easy to detect and repair and aims at solving the problems that once an existing rotary kiln barrel body surface waste heat utilization device goes wrong, detection and repair are hard. According to the rotary kiln barrel body surface waste heat utilization device, a heat collecting cover of an original rotary kiln barrel body surface waste heat utilization device is divided into three heat collecting covers which respectively cover a welding elbow, a heat exchange straight pipe bundle, another welding elbow. The rotary kiln barrel body surface waste heat utilization device is improved in adaptability. Points prone to corrosion are exposed on the body of the rotary kiln barrel body surface waste heat utilization device so that maintenance difficulty is reduced, and a large number of materials and a large amount of manpower are saved.

Description

technical field [0001] The invention relates to a technology for utilizing waste heat on the surface of a rotary kiln cylinder, in particular to a device for utilizing waste heat on the surface of a rotary kiln cylinder. Background technique [0002] At present, the waste heat utilization device of the rotary kiln shell will encounter the problem of the heat exchange tube bundle being corroded during use. Once the heat exchange tube bundle is corroded, it will cause the leakage of the heat exchange medium in the heat exchange tube bundle, which will affect the heat exchanger itself and the rotary kiln. The kiln shell is harmful. In the current rotary kiln shell waste heat utilization device, the heat exchange tube bundles and welding elbows are completely placed inside the waste heat utilization device. Once a leak occurs, all waste heat utilization devices must be opened to repair, which consumes a lot of manpower and material resources. [0003] In view of the above-menti...
