Design and performance of ductless self-cleaning chemical cabinet
摘要：
药剂挥发是造成化学、生物类实验室空气污染的主要原因之一。为控制此类实验室的空气质量，应用真空紫外线光催化-臭氧催化分解联合空气净化技术，设计开发了无管式自净药品安全柜。通过实验测定，确定了净化模块的关键参数：真空紫外线光催化单元气流的停留时间为30 s，臭氧催化分解单元催化剂的床层厚度为3 cm。测试结果表明，样机的净化效果能满足标准要求。
Abstract：
One of the main sources of air pollution in chemical and biological laboratories is the chemical pollutants released from reagent bottles. In order to improve the air quality in such locations, designs the ductless self-cleaning chemical cabinet adopting the air cleaning technology combined vacuum ultraviolet photo-catalytic and ozone catalytic decomposition. Determines the key parameters of the cleaning module based on the experimental data—the time for photo-catalytic reaction is 30 s, and the bed depth of the ozone decomposition unit is 3 cm. The test results show that the cleaning effect of the model machine can meet the requirement of the standard.
