Air pollution and internal combustion engine emissions. The atmosphere, which exists from the surface of the earth to hundreds of kilometers high, is composed of many kinds of gases. Why is organic waste gas purification equipment so important? It is generally believed that the atmosphere is composed of dry and clean air, water vapor and suspended particles. The dry and clean air on the ground is basically composed of nitrogen, oxygen, argon and carbon dioxide. Other ingredients only account for about 0.004 heats. The content of water vapor in the atmosphere changes, and the volume of water vapor related to these gases accounts for about 1-3% of all air.  

     The atmosphere is an indispensable material for human beings and all living things to live and make a living. The amount of air inhaled by the human body is about 10000 liters every day, which is indispensable for cooking, heating, burning coal and even driving cars.

     Now, air pollution has become a social and international public hazard, especially in industrialized countries, which has become a serious problem, promoting people's attention to environmental protection.

     Air pollution is closely related to the use of power by human beings. Air pollution in countries with developed industries has its own process of occurrence, development and evolution. Many scholars have studied and classified the types and characteristics of air pollution. Although air pollution is affected by a variety of factors, its status has also changed, so waste gas purification is required.

     Human beings and all living things need to draw nutrients from the environment and bring forth new ones in order to make a living and activities. Human life is closely related to the environment, so it is necessary to purify the exhaust gas to maintain the air quality, and to maintain the cleanness of the atmospheric environment closely related to people and all living things. Human beings obtain material energy from the environment through production activities, create wealth, and at the same time, pollute and damage the environment. Environmental pollution and damage will have adverse impacts on climate, biology and ecology, thus affecting the development and livelihood of human beings. Therefore, human beings should strive for harmony and balance with the environment and living creatures.
