Abstract

The invention discloses a desulfurized gypsum calcination apparatus which comprises a hot gas source device, a gypsum conveying device, a calcination device and a tail gas absorption device, wherein the hot gas source device is connected with the inlet end of the calcination device through a first pipeline; the outlet end of the calcination device is connected with the tail gas absorption device through a second pipeline; the bottom of the calcination device is connected with a third pipeline; the inlet end of the third pipeline is connected with the gypsum conveying device; and the outlet end of the third pipeline is connected with the calcination device. By using the above manner, the desulfurized gypsum calcination apparatus has a simple structure, can ensure sufficient gypsum supply to the inside of the calcination device, ensures the continuity of the calcination process, ensures the full integrality of the calcination process and improves the calcination efficiency.

Description

technical field [0001] The invention relates to the field of gypsum calcining, in particular to desulfurized gypsum calcining equipment. Background technique [0002] The production of building gypsum adopts dry calcined gypsum process. In foreign countries, before the 1960s, traditional slow-fired intermittent woks and external-fired rotary kilns were the mainstays. In the late 1960s, the above equipment was technologically transformed. In the 1970s, intermittent woks were developed It became a continuous frying pan, and developed into a conical frying pan after the 1980s; the rotary kiln also developed from the external firing type to the internal firing type calcination; in order to promote the technological progress of the gypsum industry and increase the operating speed of the gypsum building material production line, and The air-flow rapid calcination process was developed. [0003] In the prior art, insufficient calcination of gypsum often occurs in the process of c...
