摘　　要：针对启普发生器使用过程中存在液体使用量大、反应溶液利用效率低、安全性差等问题,研制了一种新型的气体发生器。该装置由储液杯、流量调节器、排气管和反应容器组成。利用流量调节器将反应液滴加到固体药品上,固-液反应充分,排出的废液基本不含反应试剂,大大减少了液体药品的用量。实验结果表明,该新型制气装置具有液体试剂用量少、利用效率高、安全性能优良、操作方便,同时兼具随开随用等特点,可有效地应用于化学实验教学中。In view of the use of a large quantity of liquid,low utilization rate of reaction liquid,and poor safety of the Kipp＇s apparatus,this paper designed a new gas generator,which was composed of a liquid storage cup,a flow regulator,an exhaust pipe and a reaction vessel.Liquid reactants were added into the reaction vessel by the flow regulator and reacted completely with solid reagents,and discharge liquids contained very few liquid reactants.Therefore,the amount of liquid reactants required was greatly reduced.The experimental results showed that the new device had the advantages of little dosage of liquid reactants,high efficiency,good safety performance,and convenient operation.Meanwhile,it had the characteristic of the immediate use just like Kipp＇s apparatus.It could be effectively applied in chemical experiment teaching.
