Sterilization and purification reactor module and stand-type air purification and sterilization device incorporating it

The present invention relates to a sterilization and purification reactor module and a stand-type air purification sterilization device incorporating the same, and more particularly, to a stand-type air purification sterilization device with a built-in sterilization purification reactor module that can be used while standing on a flat surface.

Modern people live more than 90% of the time indoors and breathe a large amount of air together with people around them. Therefore, indoor air quality has a great significance for public health. In particular, due to the coronavirus outbreak in 2019, indoor air quality management in multi-use facilities and infection control of respiratory diseases are emerging as very important social issues.

In general, indoors of multi-use facilities such as schools, hospitals, shopping malls, underground and subway stations contain fine dust, foreign substances, or microbial contaminants, and these contaminants are to provide.

In particular, as filters of air conditioners and general air purifiers have been reported as an infection medium of coronavirus, the use of air conditioners and air purifiers in educational facilities and medical facilities is partially restricted.

Existing air purifying and sterilizing devices use a pulp or glass fiber HEPA filter to collect fine dust, but efficiency such as input loss over time decreases, and expensive filters are periodically replaced. There was a problem that had to be addressed.

For sterilization, ultraviolet and anion-type sterilizers are widely used. However, ultraviolet-ray-only sterilizers have a disadvantage in that they consume a lot of power, and anion-type sterilizers have a disadvantage in that the reliability of sterilization is poor.

6 illustrates a process of photocatalytic coating of nanotubes according to an embodiment of the present invention. Hereinafter, a photocatalytic coating process of a nanotube according to an embodiment of the present invention will be described with reference to FIG. 6 .

In order to increase the photocatalytic efficiency of the nanotube, a process of increasing the spreadability (wettability) of the photocatalyst while reducing the surface energy of the base material is required.

The process of reducing the surface energy of the base material first cleans the base material. That is, in the first washing, the base material is washed using ultrasonic waves in a state in which the washing agent is added.

After the first washing, the base material is washed a second time. Unlike the first washing, the secondary washing uses ultrasonic waves in pure distilled water to clean the base material. As such, the present invention washes the base material at least twice in different environments.

The base material that has undergone the washing process is subjected to an electric drying process. Electric drying is performed at 120° C. for 60 minutes. Next, we will look into ways to increase the photocatalytic spreadability of nanotubes.

To increase the spreadability of the photocatalyst, the photocatalyst is applied in the form of a spray to the base material that has been washed and dried. The particle size of the photocatalyst is preferably 36 to 10 nm. Afterwards, the Young's modulus is measured. The contact angle should be less than 10ㅀ. In a state where the surface energy of the base material is low, the photocatalyst is applied thinly and uniformly to the base material. After that, the photocatalyst-coated base material is electro-dried, and the electro-drying is performed at 120° C. for 60 minutes.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom. .
