一种模拟大气中发生光化学反应的实验装置及其实验方法
摘要：
一种模拟大气中发生光化学反应的实验装置及其实验方法，涉及一种实验装置及其实验方法，本发明可以模拟大气中特定污染物发生光化学反应的过程及污染物的转化情况。该套实验装置首先利用真空泵将反应装置中的气体抽出，然后通入背景吹扫气体对箱体进行吹扫，接着进行再次抽真空处理，经过几次循环后待反应装置内的气体达到要求后通入反应气体进行光化学反应的模拟实验，实验开始时保持箱体内的气压略高于外部大气压，这样既有利于取样分析，同时还能防止外部气气的渗入对反应造成干扰，有利于模拟反应的顺利进行。本发明的实验装置具有操作简单、采样分析方便，比较适合模拟光化学反应的实验室研究。
摘要（英）：

The invention relates to an experiment device and an experiment method, and concretely relates to an experiment device for simulating a photochemical reaction in atmosphere, and an experiment method thereof. The device and the method can simulate the photochemical reaction process and the conversion condition of specific pollutants in the atmosphere. The experiment device uses a vacuum pump to extract a gas in a reactor, a background purge gas is used to purge a box body, then vacuumizing treatment is carried out, above steps are repeated multiple times to make the gas in the reactor reach requirements, a reaction gas is introduced to carry out the simulation experiment of the photochemical reaction, and the pressure in the box body is kept to be slightly higher than external atmospheric pressure at the beginning of the experiment in order to facilitate sampling analysis, prevent the interference of infiltration of external gas to the reaction and facilitate the smooth proceeding of the simulated reaction. The experiment device has the advantages of simplicity in operation, convenience in sampling and analyzing, and suitableness for the laboratory research of the simulated photochemical reaction.
