Description

Eco-friendly virus sterilization device using chlorine dioxide {ECOFRENDLY VIRUS STERILIZATION DEVICE USING CHLORINE DIOXIDE}

The present invention relates to an environment-friendly virus sterilization apparatus, and more particularly, to an environment-friendly virus disinfection apparatus using chlorine dioxide that sterilizes viruses with an environment-friendly disinfectant.

Coronavirus Infectious Disease-19 is a respiratory infection caused by a new type of coronavirus (SARS-CoV-2) that first emerged in Wuhan, China in December 2019 and has spread worldwide.

Coronavirus Infectious Disease-19 is transmitted when droplets (saliva) of an infected person penetrate the respiratory tract or the mucous membranes of the eyes, nose, and mouth. After an incubation period of about 2 to 14 days (estimated), the main symptoms are fever (37.5 degrees), respiratory symptoms such as cough or shortness of breath, and pneumonia.

The COVID-19 virus, which has spread worldwide, is spreading rapidly in Korea as well, causing great social and economic chaos.

The odor control and sterilization method using chlorine dioxide (ClO₂) has been used as a disinfectant in water purification plants since the 1950s, and its safety has been verified and widely used in many developed countries.

The U.S. Environmental Protection Agency (EPA) has approved (21164-3) for drinking water, factory wastewater treatment, and environmental purification, and the U.S. Food and Drug Administration (FDA) has approved its use as a food additive, medical device and disinfectant (CAS Reg No. 10049-). 04-4) is the current situation.

In addition, the World Health Organization (WHO) classified it as A-1, the safest grade among food additives, and the UN Special Committee on Food Additives also gave it an acceptable human intake (ADI) grade of A-1. In Korea, the Ministry of Environment, the Ministry of Agriculture and Forestry, and the Ministry of Food and Drug Safety have recognized it as a food additive, food disinfectant, foot-and-mouth disease, and highly pathogenic avian influenza sterilizer.

Chlorine dioxide (ClO₂) is used in the water purification process with about 2.5 times better disinfection ability than chlorine, and recently, it is also widely used in the odor treatment process. Against this background, the generation rate of THMs (trihalomethanes) and HAAs, both known as disinfection by-products and carcinogens, is low, and compared to UV and ozone processes, they are economically attracting attention as an oxidizing agent that replaces chlorine.

In addition, chlorine dioxide (ClO₂) completely dispels the fear of causing unexpected damage by remaining in the atmosphere due to its optical decomposition property that is completely decomposed by ultraviolet rays. And, chlorine dioxide (ClO₂) is a neutral chlorine compound with an oxidation state of +4, and shows high solubility in cold water. If the temperature is above 11℃, record the solubility about 10 times that of chlorine. In addition, unlike chlorine, which is hydrolysed in water, chlorine dioxide (ClO₂) is decomposed 7 to 10 million times slower, so it exists in the form of a dissolved gas in solution.

As such, the existing chlorine dioxide water has the advantage of being widely used as a disinfectant for food disinfection, wastewater treatment, environmental purification, and infectious disease virus, easy to use by mixing with water, and easily decomposed in post-treatment. It was somewhat difficult to use while observing the prescribed concentration in an everyday environment, not the place of use.

Chlorine dioxide water has an exposure limit above a certain concentration. The human body also has a problem if it is exposed to excessive time or chlorine dioxide water over a certain concentration. Accordingly, the US Occupational Safety and Health Administration limits 0.1 ppm as the exposure limit.

Ordinary people can sterilize by filling the humidifier with chlorine dioxide water instead of the water in the humidifier, and spraying chlorine dioxide water into the air in a humidified state. However, since chlorine dioxide water is harmful to the human body exposed to a certain concentration or more, it requires considerable caution when using it. .
