A bionic nose intelligent gas filtration system and gas filtration method

Abstract

The invention discloses a bionic nose intelligent gas filtering system and a gas filtering method. The system comprises a shell (1), in which a cavity (1-1) is arranged; the cavity (1-1) is respectively provided with a second A dust porous filter screen (11), the second selective porous filter screen (10) and the third selective porous filter screen (12); the top of the housing (1) is provided with a functional liquid container (6), and its internal storage There are a variety of functional liquids, a variety of detergents and control devices for each liquid; a gas sensor (4) is arranged at the bottom of the upper cover plate (2), and the gas sensor (4) is used to analyze the components of the gas to be filtered, and It converts the information into corresponding electric signals; it also includes a control circuit (3), which receives the electric signals from the gas sensor (4), and analyzes the information to issue corresponding control instructions to the detergent and functional liquid containers (6). The invention can make the device have strong anti-pollution performance and high filtration efficiency; the device can be used for a long time without replacing the filter membrane.

Description

technical field [0001] The invention relates to the field of gas filtration. Specifically relates to a bionic nose intelligent gas filtering system and a gas filtering method. Background technique [0002] The filtering and cleaning function of the nose is because the nose has three lines of defense to deal with the air containing dust, bacteria, virus or mold. The first line of defense is the nasal hairs in the front of the nose, which are like thorns at the entrance of the hole, which can block larger dust. The second line of defense is the most important and is the movement of cilia in the mucous membrane. There is a layer of mucus blanket on the surface of mucocilia, which can stick to bacteria or dust particles and send them to the back of the nose for discharge. The third line of defense is the lysozyme, interferon and secretory antibodies contained in the mucus layer, which can restrain many bacteria and viruses. After the baptism of the above three lines of defen...

Problems solved by technology

Combining the above various filtration methods, on the one hand, some of them have problems such as low filtration efficiency, singleness of filtered or purified gas, complex filtration devices, easy pollution, and limited service life. To ensure the long-term performance of the filter, but frequent replacement also affects the convenience of the device, so the anti-pollution of the device will also be reduced

On the other hand, the application field of this kind of filtering device or method is limited, and the flexibility of the device scale is also limited, that is, the universality of the device is not good.

[0004] In addition, although some of the existing methods or devices provide replaceable filter screens, most of the replacement methods are manual, and it is impossible to analyze the composition of the gas before filtering, so as to carry out effective filter replacement. Selectively filter out toxic components or parts that need to be excluded, that is, the filtering effect of gas is single, and the consistency of gas filtering is low
