Description

technical field [0001] The invention relates to the field of air purification, in particular to an air purifier. Background technique [0002] Air pollution is also a serious problem facing our country at present. China is the world's largest coal producer and consumer. About 78% of electricity, 60% of commercial energy for civilian use and 70% of chemical raw materials rely on coal. The direct combustion of coal is the most important source of anthropogenic air pollution in China. [0003] China's motorcycle production ranks first in the world, and its automobile production ranks eleventh in the world. Although the number of cars in use is far lower than in developed countries, the air pollutants per kilometer emitted by domestic cars are 3 to 5 times that of European cars. Because the road system facilities in Chinese cities are poor, the speed of cars in urban areas is much lower than that in developed countries. The road area accounts for only 3.6% of the total area...
