Embodiment Construction

[0011] A key issue that restricts air pollution purification is that pollutant components (such as formaldehyde gas, micron-nanoparticles) and clean air components (such as oxygen) necessary for human breathing are often mixed together (such as in the same gas phase). It is very difficult to completely separate them one by one, and the existing technical principle is to try to remove these mixed pollutants by adsorption or filtration or to degrade the pollutant components through chemical reactions. This kind of principle limits the existing technology. Efficiency, effectiveness, and cost have led to the various deficiencies mentioned in the technical background. The invention utilizes that all substances can undergo phase change under certain temperature and pressure conditions. After the phase change, they can be easily separated due to the different aggregation forms of the substances, such as the separation of solid and gas, liquid and gas, or liquid Separation from solids....

Abstract

The invention provides a method and a device suitable for completely and infinitely purifying indoor or closed space polluted air. The method and the device are characterized in that a pollutant component is separated and removed through a phase change method, air is circularly introduced into a phase change device to generate phase change on the pollutant component in a gas phase to form liquid or solid so as to separate the pollutant component from a clean gas phase component, the pollutant component is stored and treated, and the clean air is continuously conveyed back into the original space. The technology does not need to use, consume or change any active material nor supplement external air, only electric energy or potable refrigeration equipment is adopted to infinitely remove any pollution component in air necessary for human respiration, and the pollution component includes but not limited to carbon monoxide, ammonia, formaldehyde, sulfur dioxide, acetaldehyde, acrolein, benzene, toluene, ethyl benzene, dimethylbenzene, styrene, benzopyrene, volatile organic compounds, PM2.5 and nano particles. By reforming an existing refrigeration component, the technology can be used for purifying various civil, industrial, military and other indoor or closed space polluted air.

Description

Technical field [0001] The invention relates to a method and a device suitable for purifying polluted air indoors or enclosed spaces, and belongs to the technical field of indoor air purification. Background technique [0002] Air pollutants can include toxic and harmful gas components and fine particles (such as micron and nano-sized particles). At present, the existing air purification technologies include: adsorption technology (such as activated carbon), photocatalytic technology (such as titanium dioxide photocatalytic degradation), filtration technology (such as HEPA high efficiency filtration), negative ion technology, negative oxygen ion technology, molecular complex technology, Photocatalyst technology, electrostatic dust collection technology, active oxygen technology, etc. The materials or media used in these methods include: photocatalyst, activated carbon, synthetic fibers, HEAP high-efficiency materials, negative ion generators, etc. Although these methods have a ...
