简易气体动式染毒装置的研制与应用

摘要

Objective To develop a gas dynamic exposure device with a simple structure.Methods The device was composed of a water tank, an gas chest, an exposure kit and an gas-out bottle. The chest body was made of organic glass pane, drainage method was used to distribute the gas properly, and airflow was regulated with the gravity and valve.Results The device was proved to have simple structure and high effects.Conclusion The device has low cost, simple structure and properly distributed gas, and can be reused for exposure test.%目的:根据实验需求,研制一种简易气体动式染毒装置.方法:染毒装置由水箱、配气箱、染毒盒和排气瓶4个部分组成.使用有机玻璃板制作箱体,利用排水法精确配气,利用重力作用和调节阀调节气流大小.结果:该装置设计简单合理,经实际使用,染毒效果良好.结论:该简易气体动式染毒装置成本低廉、制作简单、配气精确,可以重复使用,能够满足动式染毒实验需求.
