Description
Technical Field
The invention belongs to the technical field of environmental microplastic, and particularly relates to a passive collecting device for wear particles of a vehicle-mounted tire and application thereof.
Background
Microplastic is an emerging contaminant, which may create a certain ecological risk after entering the environment and may be transported along the food chain to affect human health. Tire wear particles are wear particles generated by friction between the tread of a tire and the ground during the running of a vehicle on the road surface, and have been considered as one of the important sources of microplastic contamination. Previous studies have found that most tire wear particles have a particle size of less than 200 μm and exhibit differences depending on different types of vehicles and their load capacity, road conditions, etc. It is estimated that on average, each tire wears 4 kg in its life cycle with about 600 ten thousand tons of tire wear particles being discharged each year worldwide, with China expecting to discharge about 140 ten thousand tons. Meanwhile, the tire wear particles have a higher contribution to the amount of Traffic-source non-exhaust particulate matter (Traffic-related non-exhaust particulate matter). With the massive use and popularization of pure electric vehicles, the influence of tire wear particles on the ecological environment and the human health is more remarkable and is attracting attention.
There are many researchers currently focusing on the health risks of tire wear particles, but most of the samples adopted in research are manually scraped from the tire tread, and are difficult to represent the tire wear particles generated under real driving conditions. In addition, most of the existing devices for removing pollutants from motor vehicle traffic sources are used for treating tail gas emission, and no devices for collecting and removing tire wear particles exist, so that a large amount of formed tire wear particles enter the environment to generate negative effects. The efficient collection device for the tire wear particles is beneficial to interception, collection and removal of the wear particles generated in the running process of different types of vehicles, and can promote better understanding and management and control of the ecological environmental effects and health risks of the tire wear particles.
