一种动物室内除氨的模拟实验

A Simulant Experiment Removing Ammonia in Air in Room of Laboratory Animal

目的 实验研制一种去除动物室内有害气体的装置 ,用以去除动物室的氨 ,减少换全新风的量 ,降低能量消耗。方法 根据工业除氨的原理设计制做一种去除动物室空气中有害气体的小型装置 ,在模拟动物室内进行实验。结果 经模拟实验 ,在减少换全新风一半 ,约一半使用循环过滤空气的情况下 ,可保持室内氨浓度在 12 0 2ppm。结论 初步模拟实验证实 ,研制的装置有除氨作用 ,可减少动物室的换全新风的量 ,其实用价值和应用价值有待进一步研究。

Objective To develop a method of removing harmful gas in air in room of laboratory animal.Methods Based on principle of removing ammonia in industry,a small-sized equipment was produced.Results Simulant experiment indicated,when both fresh air by fan and cycling air by the small-sized equipment were in turn at intervals of one hour,the concentration of ammonia was 12.02ppm in air of laboratory animal room.Conclusion The system can remove ammonia in the room to a certain extent.
