摘要： PROBLEM TO BE SOLVED: To provide a method of thermally regenerating waste gypsum cheaply by suppressing new facility investment as much as possible, by effectively utilizing the facilities of an existing asphalt plant. SOLUTION: A waste gypsum obtained by crushing and sorting waste gypsum boards is fed to a dryer 1 of the existing asphalt plant, instead of aggregate. At this time, while thermally regenerating the waste gypsum at a temperature at which gypsum dihydrate is changed to a hemihydrate gypsum by controlling the combustion amount of a burner 4, gypsum fine particle portion in the exhaust gas effluent from a dryer 1 is captured by a dry cyclone 8, a bag filter 9, and the like, and the captured gypsum fine particle portion is recovered together with the gypsum discharged from the dryer 1. Like this, if the facilities of an existing asphalt plant are utilized, waste gypsum can be cheaply thermally regenerated while suppressing new facility investment as much as possible.

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing calcined gypsum with the minimum energy at the minimum time in the method of making hydration hardening calcined gypsum from powdery gypsum dihydrate obtained by crushing waste gypsum board and separating paper.
SOLUTION: There are problems in a conventional technique about gypsum dihydrate having free water and crystal water that a long time is necessary to heat and the thermal efficiency is low, for example 55-60%, because the gypsum reaches decomposition temperature after the dehydration is completed in conduction heating such as an indirect heating system. This method is carried out by heating simultaneously with the irradiation with and absorption of infrared ray while fluidizing the gypsum dihydrate through a screw or a paddle conveyer to enlarge the heat receiving surface area for the infrared light. As a result, the heating time becomes 6-10 min and the unit consumption of heat is about ≤200 kcal/hr which means that the calcined gypsum is manufactured with nearly theoretical heat energy.

摘要翻译：要解决的问题：提供一种在从通过粉碎废石膏板和分离纸获得的粉状石膏二水合物制备水化硬化煅烧石膏的方法中以最小时间制造煅烧石膏的方法。解决方案：在具有游离水和结晶水的石膏二水合物的常规技术中存在长时间需要加热和热效率低的常规技术，例如55-60％，因为石膏在达到分解温度之后脱水在传导加热中完成，如间接加热系统。该方法通过在通过螺旋或桨式输送机流化石膏二水合物的同时加热和吸收红外线进行加热，以扩大红外光的受热表面积。结果，加热时间变为6-10分钟，单位消耗的热量约为≤200千卡/小时，这意味着煅烧石膏以几乎理论上的热能制造。版权所有（C）2006，JPO＆NCIPI

摘要： PURPOSE: To execute uniform heat treatment by establishing first and second beds of material, supplying untreated material to the first bed and transferring the partially calcined material therefrom to the second bed. CONSTITUTION: A fuel is continuously supplied via a fuel supply pipe 32 to the fluidized combustion bed in a chamber 22. Pressurized air is supplied to a pipe 28 and is admitted through a stand pipe 30 into a combustion chamber 22 to fluidize the combustion bed. The material in the beds A and B is heated by the indirect head conduction passing the wall 24 of the combustion chamber. The hot combustion gas passes into a plenum chamber 42 along ducts 38, 40 and is sent through a spurge pipe 46 into the lower regions of the beds A, B. The beds are fluidized by the hot combustion gas and is assisted by the water of crystallization generated and evaporated by the material, by which the material is further heated. The exhaust gas and steam are emitted through a discharge duct 12. A quality improvement is thereby made possible.
