Embodiment Construction

[0049] Combine below figure 2 , image 3 The present invention is described in detail, the following are only preferred embodiments of the present invention, but the scope of the present invention cannot be limited with this, especially the shape of the system, and all equivalent changes and modifications done according to the application scope of the present invention shall belong to scope covered by the present invention.

[0050] The fresh air introduced from the outside of the aircraft cabin enters the gas purification system through the air inlet 4. At this time, the valves V1, V2, and V4 are opened, and the back purge valve V3 is closed. The center tube is perforated, and the inside of the center tube is fixed with a wire mesh filter 9. The material of the wire mesh filter is stainless steel, and the mesh aperture is 200-400 orders. Fresh air filters through the wire mesh filter 9 to remove particulate matter therein. The filtered fresh air enters the ozone removal ch...

Abstract

The invention discloses a method and system for ozone removal and gas purification of a cabin of an aircraft. The method comprises the steps of introducing fresh air outside the cabin, filtering out microbes and particulate matters in the fresh air, catalytically converting ozone in the fresh air into oxygen gas through a catalyst, cooling the oxygen gas, then, mixing the cooled oxygen gas with recirculated air in the cabin, carrying out adsorptive filtration on the gas mixture so as to further reduce incompletely-removed ozone, microbes and solid particles in the gas mixture, discharging the gas mixture, which is subjected to adsorptive filtration, from a system, and enabling the gas mixture to enter the cabin. The system comprises a catalytic ozone removal reactor, a heat exchanger, an adsorption purifier and a desorption blowback system, or the unit plants are integrated into one reactor. The desorption blowback system is further used for purging the interior of the gas purification system so as to prolong the service life of the system. The system employs a radial reactor structure and has high ozone removal efficiency; and in purified air exhausted from the gas purification system disclosed by the invention, the ozone concentration can be controlled to 0.1mg/m<3> or below.

Description

technical field [0001] The invention relates to the field of ozone conversion and gas purification, in particular to a method and system for deozone removal and gas purification in an aircraft cabin. Background technique [0002] Ozone is an allotrope of oxygen, its molecule contains three oxygen atoms, and its molecular formula is O 3 , a colorless gas at room temperature, with a special grassy smell and strong oxidative power. Ozone in the top layer of the atmosphere is beneficial to human beings, it can effectively absorb harmful ultraviolet radiation, but near the ground, ozone with strong oxidizing properties is harmful to human beings and their living environment, it can not only strongly stimulate human respiratory tract , causing a variety of respiratory diseases, but also an important component of photochemical smog. If the ozone concentration in the environment reaches 0.06mg / m 3 When exposed to it, people will have headaches, dry throat, damage to the respirato...
