Processing technology for producing high-strength gypsum powder by using ardealite and desulfurized gypsum products
The invention discloses a processing technology for producing high-strength gypsum powder by using ardealite and desulfurized gypsum products, and relates to the technical field of gypsum powder production. In the processing technology of the gypsum powder, ardealite and desulfurized gypsum are reasonably compounded, the acid-base degree is adjusted after the ardealite and the desulfurized gypsum are combined, the obtained powder is close to natural gypsum, and the powder and the natural gypsum complement each other in grain composition, so that the strength of a finished product can be improved, natural gypsum can be replaced, industrial waste is fully utilized, waste is turned into wealth, the environment is protected, natural gypsum resources are saved, and the cost is low. According to gypsum powder production equipment, an induced draft fan is matched with a heat return pipe for use, water vapor generated by calcining mixed gypsum can be pumped out and conveyed into the heat storage bin through the heat return pipe, heat is transferred to the mixed gypsum under the condition that the water vapor does not make contact with the mixed gypsum, first, the mixed gypsum is initially dried, energy is recycled, resources are saved, and the calcining condition and time of the mixed gypsum are reduced.
本发明公开了一种利用磷石膏与脱硫石膏制品生产高强度石膏粉的加工工艺，涉及石膏粉生产技术领域，该石膏粉的加工工艺中通过将磷石膏与脱硫石膏合理复配，两者结合之后在酸碱程度上得到调整，与天然石膏相近，在颗粒级配上相互弥补，可提高成品的强度，从而可以替代天然石膏，充分利用工业废料，变废为宝，保护环境，节约天然石膏资源，成本低；石膏粉生产设备通过引风机配合返热管使用，能够将煅烧混合石膏产生的水汽抽出，并经过返热管输送至蓄热仓中，使得水汽不与混合石膏接触的情况下将热量传递至混合石膏，首先将混合石膏进行初步烘干，回收能量、节约资源的同时降低混合石膏的煅烧条件与时间。
