PM2.5 purification system for electric automobile

Abstract

The invention discloses a PM2.5 purification system for an electric automobile. The PM2.5 purification system comprises a friction particle trapping device, a brake particle trapping device, a purification chamber and a fan. The friction particle trapping device is arranged on a vehicle body above the wheels; the brake particle trapping device is arranged on one side of an automotive brake; a suction filtration element is arranged in the purification chamber. According to the system disclosed by the invention, the fan serves as dust-containing driving force, friction dust of automobile tires and brake dust of the automotive brake can be sucked into the purification chamber to be efficiently purified, and pollution of PM2.5 to the environment is eliminated; by utilizing the high-pressure air counter-blowing ash removal technology, the problem that the suction filtration element is difficult in ash removal is solved, and continuous and high-efficiency operation of the PM2.5 purificationsystem is ensured; by utilizing the pushing technology, the collected PM2.5 is cleaned and pressed into bricks, and pollution of dust re-entrainment to the environment is avoided. The purification system disclosed by the invention is integrated on the vehicle body, and has the advantages of being compact in structure, reliable in operation, high in purification efficiency and the like.

Description

technical field [0001] The invention relates to an electric vehicle PM2.5 purification system. Background technique [0002] An electric car is called an environmentally friendly car because it has no tailpipe emissions. However, research by scientific research institutions such as the Georgia Institute of Technology in the United States has shown that toxic and harmful particulate matter such as PM2.5 emitted by electric vehicles is as serious as the internal combustion engine vehicles they will replace. These dust particles are produced by tire and brake system wear. Both fuel vehicles and electric vehicles are no exception, but electric vehicles produce more particles. This is because electric vehicles are equipped with heavy power batteries and other drive components, making the body weight about 30% higher than other vehicles. This means that when accelerating or braking, tires and braking systems wear faster and produce more harmful particles. The British "Atmosphe...

Problems solved by technology

For this reason, scientists from all over the world have proposed to solve the problem by changing tires and pavement materials. This solution takes a long time, is difficult, and requires a huge investment, so it is difficult to put it into practice.

Scientists in the United States and Germany proposed to reduce the weight of the vehicle body, but due to the battery life requirements of the power battery, it is difficult to reduce the weight of the electric vehicle itself

So far, the problem of eliminating the pollution of toxic and harmful dust particles such as PM2.5 from electric vehicles has not yet achieved substantial progress and solutions
