Background technique

At present, the flue gas purifier is widely used in the purification treatment of waste flue gas discharged from coal combustion, boilers, industrial production equipment and motor vehicles.

Harmful and toxic gases and dust particles in the exhaust gas emitted by various coal-fired and fuel-fired equipment in industrial production and civil life can seriously pollute the environment, especially harmful gases such as chlorine dioxide will combine with water molecules in the air to form " Acid rain", falling to the ground and causing serious damage to vegetation. In addition, the dust and carbon particles in the flue gas will also cause environmental pollution and endanger human health.

In particular, in large and medium-sized cities in China, vehicle exhaust emissions have become the main source of air pollution. At present, the number of automobiles in use in China is very large. However, with the rapid economic development and the increase of social needs, the number of automobiles in China will increase at an average annual rate of 9% in the next 10 to 15 years. This shows the urgency of reducing automobile exhaust emissions. Automobile tail gas purification catalyst is an effective means to control automobile emission and reduce automobile pollution. Precious metals are mainly used as catalysts and rare earth automobile exhaust gas purification catalysts. Because these precious metals are expensive, it is difficult to widely promote them.
