Abstract

The invention discloses a radon removal purification method and device, and aims to solve the problems that uncombined radon daughters in air are difficult to effectively remove and the overall treatment efficiency is not ideal in the prior art. The radon removal purification method comprises the following steps: firstly, filtering radon daughters carried by aerosol from input air to be purified to obtain primarily purified air; then drying the primarily purified air to remove moisture; and then using the cold trap segregation and low-temperature adsorption principle for conducting physical refrigeration and adsorption on the dried air, so as to obtain fully purified air. According to the invention, the traditional radon removal and purification design thought is broken through, the physical properties of radon are utilized, non-combined radon with larger radiation dose pollution is removed through cold trap segregation and low-temperature adsorption, and meanwhile, combined radon daughters are filtered through dust removal, so that radon in air is removed more quickly and efficiently.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a method and device for removing radon pollution in the air. Background technique [0002] Radon is a colorless and odorless inert gas produced by the decay of radium in nature. Radon has three natural radioactive isotopes, Rn219, Rn220, and Rn222, among which 222Rn is the most important and longest-lived, with a half-life of 3.82 days. Under standard conditions, the density of radon is 9.73kg / m3; its liquefaction point is -62°C and freezing point is -71°C under standard atmospheric pressure. Radon is one of the 19 important carcinogens announced by the World Health Organization. Its radiation in life is far greater than the sum of other radiation hazards. The incubation period for inducing lung cancer is more than 15 years. Radon atoms decay spontaneously into charged radon daughters, attach to aerosols in the air, enter the human body and deposit in the respiratory t...
