Device for simulating photochemical reaction of air pollutants

Abstract

The invention discloses a device for simulating the photochemical reaction of air pollutants. The device comprises a static mixer, an internal flowing pipe and an external flowing pipe, the internal flowing pipe is fixed to the interior of the external flowing pipe, and a tubular cavity used for allowing recycled water to flow by is formed between the internal flowing pipe and the external flowingpipe; the lower part of the external flowing pipe is provided with a water inlet, the water inlet is communicated with a flow outlet of a water tank through a water inlet pipe, a water pump is arranged on the water inlet pipe, the upper part of the external flowing pipe is provided with a water outlet, and the water outlet is communicated with a reflux port of the water tank through a water outlet pipe; a plurality of ultraviolet lights are evenly arranged surrounding the external flowing pipe in the circumference direction, and the static mixer is communicated with the internal flowing pipe,the static mixer is provided with an air inlet, and the internal flowing pipe is provided with air outlet. The device can conduct real-time simulation on the photochemical reaction of the real air pollutants, has the extremely high simulation fidelity, can simulate nearly the same photochemical reaction as that of the real air pollutants, and has the advantages of being easy to operate and easy to achieve.

Description

technical field [0001] The invention relates to the technical field of photochemical reaction analysis of air pollutants, and more specifically, the invention is a device for simulating photochemical reactions of air pollutants. Background technique [0002] The impact of air pollution on human health and ecological environment has been widely concerned by the government and citizens. Photochemical reactions are an important way for the transformation of air pollutants. The existing technology generally uses an air quality model to conduct simulation research in a sealed cabin. Although it can explain some simple photochemical reactions of air pollutants, due to technical bottlenecks in existing devices for simulating photochemical reactions of air pollutants, it cannot Real-time research and analysis of photochemical reactions in ambient atmospheric aerosols, and it is impossible to carry out long-term photochemical reaction research, and it is impossible to accurately anal...
