Abstract

The invention provides an environment testing box for simulating a seriously-polluted atmosphere. The environment testing box comprises a photochemical smoke polluted environment simulation system and a detection system, wherein the photochemical smoke polluted environment simulation system comprises an upper-cold and lower-hot convection generation device, an ultraviolet lamp tube, a heat radiation plate, a carbon dioxide generator, a nitric oxide generator and a water vapor generation device; and the detection system comprises a sample rack, a multi-pipeline infrared gas analyzer and a temperature recorder which are arranged in the box body. Compared with the prior art, a generation condition of photochemical smoke in the seriously-polluted atmosphere can be stably simulated; the environment testing box can be stably operated for a long time, and a long-time corrosion and ageing test can be carried out on a material; a heat pump is used, and heating and refrigeration energy conservation can be realized; and the environment testing box is simple and convenient to maintain.

Description

technical field [0001] The invention relates to a test box, in particular to an atmospheric environment test box for simulating the influence of photochemical smog on original devices and material properties under severe pollution conditions. Background technique [0002] Photochemical smog is mainly caused by automobile exhaust and industrial exhaust emissions. Olefin hydrocarbons and nitrogen dioxide (NO2) in automobile exhaust 2 ) is emitted into the atmosphere, under the strong ultraviolet rays of the sun, it will absorb the energy of sunlight. After absorbing the energy of sunlight, the molecules of these substances will become unstable, and the original chemical chains will be destroyed to form new substances. This chemical reaction is called photochemical reaction, and its product is highly toxic photochemical smog. [0003] The increase in sunlight ultraviolet radiation due to stratospheric ozone depletion will accelerate the degradation and aging deterioration of ...
