The present invention relates to an air sterilization and purification device, and more specifically, a plurality of string members made of synthetic resin material are stretched and expanded to form a cylindrical purifying member, and a photocatalyst is impregnated and applied to the purifying member to pass through. The present invention relates to an air sterilization and purification device capable of maximally sterilizing and purifying the air by filtering and sterilizing the air.

In general, air pollution causes various diseases such as various skin diseases, respiratory diseases, and water-borne diseases as physical and chemical changes occur in the air due to inflow of soot, various incineration facilities, and volatile organic compounds.

These pollutants cause serious problems to humans and animals, and for this purpose, many devices for improving air quality have been proposed.

Existing air purifiers collect foreign substances such as dust by using a filtration method by manure of a filter, an electric dust collection method that collects foreign substances using an electric field, and an activated carbon adsorption method that removes foreign substances by adsorbing them to activated carbon.

However, existing air purifiers have only filtering filters, so they can easily adsorb dust, but sterilization of viruses and bacteria and removal of odors are not easy. In addition, existing purifiers have disadvantages in that the air purifying efficiency is remarkably lowered and the structure is not efficient because the air purifying section is small because the filter is formed in the form of a film.

Therefore, there is a need to improve this.

The main body 100 is configured to include a purifying member 200 filtering air and applying a photocatalyst 210 for sterilization.

The main body 100 is formed in a square cylinder shape in which an air movement space is formed in the center. The main body 100 is provided with a first flange portion 110 curved up and down on both sides, and is connected to the second flange 31 of the case 310 of the air intake and discharge portion 300 to be described later by bolting.

The purification member 200 is molded by hanging a plurality of strands of string member 20 discharged from the extruder 10 in a coil form on the mold 30, and the cylinder 40 provided at the inlet of the mold 30 It can be formed by operating the narrowly gathered and then cutting with the cutting member 50, and applying the photocatalyst 210 so as to be impregnated.

The string member 20 may include a synthetic resin material having a set thickness.

The photocatalyst 210 is blended so that the purification member 200 is impregnated with titanium dioxide (TiO ₂ ) and paint and bonded, and after being applied to the purification member 200, titanium dioxide is added one or more times to increase the purification efficiency. It can be applied and formed.

The purification member 200 is formed in a cylindrical shape and is disposed inside the body 100 in the form of a square cylinder to impregnate and bond the photocatalyst 210 contained in the air flowing through the applied air, algae influenza, various viruses and pathogens It can remove germs, decompose various organic substances, remove various odors, and remove various harmful substances such as ammonia, formaldehyde, and dioxin. Of course, the purifying member 200 may be changed and formed into various other shapes such as a square column shape.

The purification member 200 may have a porosity in the range of 91 to 93% to allow air to pass through. At this time, the porosity of the purifying member 200 is most appropriate at 92%.

In the state in which the photocatalyst 210 is applied through the spraying member 60 so as to be impregnated and bonded to the purifying member 200, its activation is promoted through ultraviolet rays emitted from the light irradiation unit 400, thereby increasing the purifying efficiency. The injection member 60 is sprayed around the purifying member 200 so as to be impregnated and bonded. The purification member 200 may be impregnated and bonded by being immersed in a water tank containing a liquid photocatalyst.

Subsequently, as shown in the second drawing of FIG. 7, by operating a pair of cylinders 40 provided at the inlet side of the mold 30, the plurality of string members 20 are closed to the center. At this time, since the purifying member 200 formed by the gathering of the string members 20 of a plurality of strands maintains a hardened state, it is hardened in a form tailored to the mold 30. Of course, the shape may not be completely standardized by the multi-stranded string member 20 falling through the extruder 10, but to filter out foreign substances including dust in a state with a gap according to the shape of the mold 30 It may be possible to serve as a filter for giving.

Then, as shown in the third drawing of FIG. 7, the cutting member 50 is used to cut the portion where the plurality of string members 20 are gathered to form the final purification member 200.

And, as shown in the fourth drawing of FIG. 7, the photocatalyst 210, titanium dioxide, and paint are sprayed onto the purifying member 200 using the spraying member 600 to form an impregnated and bonded coating. At this time, the paint mixed with titanium dioxide may include varnish paint and the like.

Meanwhile, the purifying member 200 according to an embodiment of the present invention may be applied more than once by adding titanium dioxide to the purifying member 200 through the spraying member 60 to increase the purifying efficiency. In particular, when titanium dioxide is added to the purification member 200 and applied two or more times, the durability of the photocatalyst 210 is further increased, and the purification efficiency of the purification member 200 can be maintained for a long time even when used for a long time.
