Problems solved by technology
However, during the use of the steam calciner, since the gypsum powder contains chloride ions and sulfate ions, etc., in a high-temperature and high-humidity environment, chloride ions and sulfate ions will corrode the steam heating tube, causing the steam heating tube to leak. The steam heating tube is welded and fixed on the side wall of the container, and there are many welding positions, so it is difficult to disassemble and maintain the steam calciner.

This paper provides a steam calciner, comprising: a container; a first horizontal steam pipe, which is movably installed on the side wall of the container; a steam heating tube group, which is detachably installed in the container; and a condensed water outlet pipe, It is located below the steam heating tube group and is movably worn on the side wall of the container; wherein, the radial inner end of the first horizontal steam pipe is connected to the upper end of the steam heating tube group, and the radial inner end of the condensate outlet pipe The end is connected with the lower end of the steam heating tube group. In the steam calciner, the steam heating tube group is detachably installed in the container. After the steam heating tube group leaks, the first horizontal steam pipe and the condensed water outlet pipe are disconnected, and the steam heating tube group and the container are separated, that is, The steam heating tube group can be taken out, and the steam heating tube group can be repaired. There are few welding positions in this process, and the disassembly and maintenance of the steam calciner is relatively simple.
Description
technical field [0001] This article relates to the technical field of gypsum board production, especially a steam calciner. Background technique [0002] In the building gypsum industry, the properties of the calcined gypsum powder are critical. Due to the good heat transfer effect, uniform temperature distribution, low equipment investment, and no mechanical moving parts inside, steam calciners are more and more widely used. However, in the process of using the steam calciner, because the gypsum powder contains chloride ions and sulfate ions, etc., in the high temperature and high humidity environment, chloride ions and sulfate ions will corrode the steam heating tube, causing leakage of the steam heating tube. The steam heating tube is welded and fixed on the side wall of the container, and there are many welding positions, and it is difficult to disassemble and maintain the steam calciner. SUMMARY OF THE INVENTION [0003] The present application provides a steam calc...
