所推荐的设备是为了氯化铝并排除放热过程中放出的多余热量。设备(见图)有一个直径～84厘米的钢制筒形外壳1,内部有一层厚226毫米的耐火混凝土内衬。活盖3用螺栓4紧固。经过内径78毫米的管子5装入12.5～25毫米的铝块。阀门6和7相隔117厘米,这样能定期地向设备中投加铝料,而不必耽心AlCl_3排到大气 The recommended equipment is for aluminum chloride and eliminates the excess heat released during the heat release. The device (see picture) has a steel tubular housing 1 with a diameter of ~ 84 cm and a layer of 226 mm thick refractory concrete lining inside. The flap 3 is tightened with bolts 4. After passing through a tube 5 with an inner diameter of 78 mm, load 12.5 to 25 mm aluminum block. Valves 6 and 7 are separated by 117 cm, so that aluminum can be added to the plant on a regular basis without having to worry about AlCl_3 being vented to the atmosphere
