Device and method for purifying air from non-desired components and for eliminating such components

摘要

A device for purifying air from non-desired gases and particles, in the case of nuclear power plants from radiating particles and gaseous iodine, and for extermination of microorganisms and removal from the air. The device includes a purifying chamber through which the air to be purified is arranged to flow. In the structurally grounded purifying chamber ionized air (1) is led to a water dust or vapor which can be oxidized with hydrogen peroxide (6) and by increasing the voltage level of the ionization to produce ozone and to be led further to high voltage operated ion blast tips (8) producing a continuous ion jet, which is directed onto collecting surfaces (9) and taking with it droplets, particulate materials and gaseous components connected to them. The volume of the air to be purified determines the shape and volume of the purifying device.

主权项

1. A device for purifying air from non-desired gases, microorganisms, droplets, particles of nano size and larger, which device comprises a purifying chamber through which air to be purified (1) is arranged to flow, said purifying chamber having a zone (6) where the air to be purified is arranged to flow through water dust or water vapor, as well as an ion blast chamber (7) having ion blast tips (8) directed towards collecting surfaces (9), whereby droplets or particulate materials included in the air to be purified and flowing through ion jets rushing from said ion blast tips (8) will be thrown against said collecting surfaces (9) being grounded, and mass collected onto said collecting surfaces will flow down to the bottom of the purifying chamber and from there to drainage (5)simultaneously as purified air will leave the purifying chamber, characterized in that in the inlet end of the purifying chamber there is an ionization chamber (3) having ionization emitting tips (4) for ionization of air (1) coming to purification before it is led through the water dust or water vapor zone (6) and in the inlet of the purifying chamber there are gas sensors (2) being connected to an electricity and control centre (10), which based on signals from the gas sensors is arranged to determine an electric charge of the ionization, either negative or positive.
