Steam calcinator

Abstract

The invention provides a steam calciner. The steam calciner comprises a container, a first horizontal steam pipe which is movably arranged on the side wall of the container in a penetrating manner, a steam heating pipe group which is detachably mounted in the container, and a condensate water leading-out pipe which is located below the steam heating pipe group and movably installed on the side wall of the container in a penetrating mode; the radial inner end of the first horizontal steam pipe is connected with the upper end of the steam heating pipe group, and the radial inner end of the condensate water leading-out pipe is connected with the lower end of the steam heating pipe group. According to the steam calcinator, the steam heating pipe group is detachably installed in the container; after the steam heating pipe group leaks, the first horizontal steam pipe and the condensate water guiding-out pipe are disconnected, the steam heating pipe group is separated from the container, so that the steam heating pipe group can be taken out and maintained; welding positions for splitting in the process are few; and therefore, the steam calcinator is easy to disassemble and maintain.

Description

technical field [0001] This article relates to the technical field of gypsum board production, especially a steam calciner. Background technique [0002] In the construction gypsum industry, the properties of the calcined gypsum powder are critical. The steam calciner (including the container and the steam heating tube welded and fixed on the container) is more and more widely used due to its good heat transfer effect, uniform temperature distribution, low equipment investment, and no mechanical moving parts inside. 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 pipe 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. Co...

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.
