The invention discloses a photochemical smoke experiment, and the device comprises a mixing chamber, a reaction chamber and an inspection chamber which are connected in sequence, wherein the mixing chamber is used for mixing reaction gas entering the mixing chamber, the reaction chamber is used for carrying out ultraviolet irradiation on the uniformly mixed reaction gas to form photochemical smog, and the inspection chamber is used for carrying out ozone amount measurement on the reaction gas forming the photochemical smog to measure the total amount of the photochemical smog; N reaction sub-chambers which are independent of one another and can receive reaction gas for ultraviolet irradiation are arranged in the reaction chamber, and the reaction sub-chambers are used for adjusting the density of the reaction gas before ultraviolet irradiation, wherein N is an integer greater than 2. The device is used for researching the influence of the density of the mixed gas on the generation of the chemical smoke in the photochemical smoke generation process, and the practical experiment device is provided for researching the generation mechanism and the control scheme of the photochemical smoke.
Description
technical field [0001] The invention relates to the field of environmental protection experiments, in particular to an experimental device for studying photochemical smog generation process and influencing factors. Background technique [0002] Photochemical smog is primary pollutants such as hydrocarbons and nitrogen oxides discharged into the atmosphere from pollution sources such as automobiles and factories, which undergo photochemical reactions under the action of ultraviolet light to form secondary pollutants. The smoke causes red eyes, sore throat, shortness of breath, dizziness, and headaches. Photochemical smog is dominated by ozone, which causes many adverse effects on air pollution, affects animals and plants, and even affects building materials, and greatly reduces visibility and affects travel. [0003] Therefore, there is an urgent need for an experimental device for studying the influencing factors in the process of photochemical smog generation, so as to pro...
