High-efficiency waste heat utilization device for cylinder surface of rotary kiln

Abstract

The invention relates to a high-efficiency waste heat utilization device for a cylinder surface of a rotary kiln. The high-efficiency waste heat utilization device comprises a rotary kiln cylinder body, a heat collecting hood and a heat exchange tube bundle, wherein the heat collecting hood is arranged on the periphery of the rotary kiln cylinder body; the heat exchange tube bundle is arranged between the rotary kiln cylinder body and the heat collecting hood; and a covering surface of the heat collecting hood on a cross section of the rotary kiln body is not smaller than one second of the cross section of the rotary kiln cylinder body. The high-efficiency waste heat utilization device further comprises a deflector which is vertically arranged at the lower part of the heat collecting hood; an electric shutter adjusting valve is additionally arranged at the top of the heat collecting hood; a temperature sensor is additionally arranged inside the heat collecting hood; and the electric shutter adjusting valve and the temperature sensor form a control system. According to the high-efficiency waste heat utilization device disclosed by the invention, the problem that that waste heat resources of a traditional heat acquiring device on the cylinder surface of a traditional rotary kiln body is low in utilization rate is solved and the utilization rate of the waste heat resources on the cylinder surface of the rotary kiln body is increased.

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 radiation heat exchange device for a rotary kiln cylinder. Background technique [0002] At present, a large amount of waste heat is generated in the production process of the rotary kiln. At this stage, the main method of utilization is to install waste heat boilers at the kiln head and kiln tail to generate steam to drive the steam turbine to generate power. However, the waste heat power generation technology at the kiln head and kiln tail can only collect flue gas However, there is no stable and safe utilization method for the radiant heat generated on the surface of the rotary kiln shell. [0003] In view of the above problems, the inventor actively researches and innovates on the basis of years of rich practical experience and professional knowledge engaged in the design and manufacture of such products, in order to create a ...
