Description

an air purification device

technical field

The utility model relates to the technical field of environmental protection equipment, in particular to an air purification device.

Background technique

With the rapid development of urbanization and industrialization and the rapid increase of energy consumption, many air pollution problems have been brought to cities. During the 1970s, soot-type pollution emissions were a major feature of industrial cities. In the 1980s, many southern cities suffered from severe acid rain. In recent years, vehicle exhaust emissions have deteriorated the air quality in many cities.

The World Health Organization has confirmed that 68% of human diseases are related to indoor air pollution. Indoor air pollution is more than five times more serious than outdoor air pollution. The Environmental Protection Agency of the United States has confirmed that indoor air pollution is the first of the 18 types of carcinogens. People breathe about 15 cubic meters of air a day, and each cubic meter of air weighs about 1.3 kilograms, which is equivalent to inhaling 20 kilograms of air every day. However, people now attach great importance to drinking pure water, but often ignore the air that is more important than drinking water. The vast majority of air pollutants are invisible to the naked eye, bacteria smaller than human cells, and particles that can enter the lungs. Once they enter the blood through breathing, they will cause the birth of various human diseases. In order to reduce diseases and create a healthy and hygienic environment for people, it is urgent to solve the problem of purification of air pollutants.
