Description

Air Purification Method and Air Purification Apparatus Based on Photo-Plasma and Ion Fusion The present invention relates to an air purification method and an air purification device, and more specifically, to an air purification method and an air purification device based on photoplasma and ion fusion that can improve air sterilization and purification by continuously generating sterilization and purification active species using photoplasma and ion reaction, and can ensure the safety of the device by preventing or minimizing the emission of ozone ( O3 ) which may affect the human body. Dust particles ranging in size from 1 nm to 100 µm are suspended in the air. Particles smaller than 10 µm are designated as PM10, while those smaller than 2.5 µm are designated as PM2.5. While particles larger than 2.5 µm suspended in the atmosphere naturally settle and are removed relatively easily, fine particles smaller than 2.5 µm are highly likely to remain suspended in the atmosphere for a long time due to meteorological influences such as temperature, humidity, and wind. As part of an effort to solve this, an air purifier has been developed and proposed. Generally, air purifiers can make the indoor environment pleasant by forcibly drawing in indoor air, filtering out dust and odors mixed in the air, and blowing it back into the room. Such air purifiers may include a blower fan and a filter. Accordingly, indoor air can be drawn into the air purifier through an intake port formed in the air purifier by the operation of the blower fan. Additionally, as the air drawn into the air purifier passes through the filter section, various dust and foreign substances contained in the air are filtered out and discharged from the air purifier's outlet; however, conventional air purifiers focus merely on circulating filtered air over a long distance. Meanwhile, recent COVID-19 Delta and Omicron variants have led to increased transmission and a decreased mortality rate. To date, there have been 6.8 million confirmed deaths worldwide and 34,000 domestic deaths, causing significant economic and social impacts and establishing a new social paradigm. Although social distancing and mask-wearing measures are being lifted, the likelihood of coronavirus variants emerging is increasing due to environmental changes caused by global warming. Recently, Omicron sub-variants (XBB lineage) of the coronavirus, accompanied by symptoms of conjunctivitis, are spreading with high transmissibility. There is vigilance regarding the spread of infection to the general public caused by viral mutations due to environmental deterioration. Along with global climate change and environmental pollution, there is a risk of outbreaks involving viruses such as influenza and bacteria, and the elderly are at a higher risk of infection due to their weakened immune systems. When the air contains viruses, a problem is emerging in that conventional air purifiers that simply perform filtering can cause the virus-containing air to spread further through the purifier. In this regard, Korean Published Patent Application 10-2014-0087352 "Air Purifier" (Patent Document 1) discloses a housing through which air flows in and out, and a filter configuration placed in an air circulation path. In the air purifier of Patent Document 1, air introduced into the housing can be discharged from the housing as it is filtered by the filter. However, the air purifier of Patent Document 1 does not recognize at all that the air flows at a slow speed so that viruses, bacteria, etc. in the air can be removed. In other words, when using an air purifier like Patent Document 1, there is a problem that viruses contained in the air cannot be removed within the air purifier and can spread far in the indoor space through the flow of air through the air purifier. In addition, the air purifier disclosed in Korean Published Patent Application 10-2018-0070525 (Patent Document 2) of LG Electronics Co., Ltd. includes an air intake section and an air discharge section, and has an outer casing in which a space is formed inside, a motor disposed inside the outer casing, a blower connected to the motor, and a filter disposed inside the casing. However, the air purifier disclosed in Patent Document 2 is moved upward by a blower and flows through a filter to be filtered, but viruses and bacteria in the air are not removed and are discharged immediately through the air discharge port. As such, Patent Document 2 also fails to recognize that air flows at a slow speed to allow viruses and bacteria in the air to be removed. In other words, when using an air purifier like Patent Document 2, there is a problem that viruses contained in the air are not removed within the air purifier and can spread far in the indoor space through the flow of air through the air purifier. As part of an effort to solve the aforementioned conventional problems, air sterilization devices have been proposed that utilize methods such as removing
