After the secondary purification by the carbon filter 540 located in the discharge through the outlet 530 to the outside.

The bio ceramic filter 550 of the present invention includes 1 to 10 parts by weight of plastic clay and 90 to 99 parts by weight of yellow clay. In addition, the bio-ceramic filter 550 further includes 5 to 10 parts by weight of kaolinite chamotte based on 100 parts by weight of a mixture of plastic clay and loess to enhance strength after drying, or 50 to 200 mesh to increase adsorption power. ) May further include 3 to 30 parts by weight of charcoal or activated carbon.

The plastic clay does not decompose ocher in water, it is possible to be molded so as to have an excellent strength as the bio-ceramic filter 550 only through a drying process without going through a firing process by increasing the viscous force of the ocher.

In addition, the plastic clay is preferably added to the water and molded in the desired shape, the shape and strength is maintained even when the moisture is dried, for example, one or two selected from the group consisting of bentonite, germanium, montmorillonite and biotite More than species. In this case, it is preferable to use bentonite.

These plastic clays include 71-73 wt% silicon dioxide, 14-16 wt% alumina, 3-5 wt% iron trioxide, 0.1-0.5 wt% titanium dioxide, 1.5-2.5 wt% magnesium oxide, 1.0-2.0 wt% calcium oxide It is preferable to include 2.0-3.0% by weight of sodium oxide and 0.1-1.0% by weight of potassium oxide, and if the content of plastic clay obtained in nature does not reach this, it is possible to add the necessary ingredients.

Plastic clays have a particle size of 180-250 mesh, preferably 200-230 mesh. In this case, when the particle size is less than 180 mesh, the viscous force of the loess cannot be increased, and the shape of the bio ceramic filter cannot be maintained after molding, and when the particle size is larger than 250 mesh, the shape of the bio ceramic filter cannot be maintained after molding.

Plastic clay is used 1 to 10 parts by weight, preferably 2 to 9 parts by weight. In this case, when the content of the plastic clay is less than 1 part by weight, the bio-ceramic filter cannot maintain its shape during molding, and the clay may be decomposed into water, which may lower the strength. When the content is more than 10 parts by weight, the mixture may be mixed with the loess. After hardening, it is impossible to mold, and the amount of ocher is reduced, so that the strength and the ability to remove harmful pollutants may be reduced.

The loess contains a large amount of calcium carbonate, the loess has a viscous force that is not easily broken by calcium carbonate, and has the property of changing to clay when water is added. In addition to calcium carbonate, ocher contains various minerals such as silica, alumina, iron, magnesium, sodium and potassium, various enzymes such as catalase, diphenoloxydiase , saccharase and protease, and Bacillus , Pesudomonas and Nitrosomonas . Contains microorganisms At this time, enzymes play a role in detoxification, degrading power, and purification, and microorganisms decompose VOC, and in particular, decompose bad smell into carbon dioxide and water.

Such ocher is a porous material, for example, a honeycomb structure having a large surface area, and has a plurality of sections forming a multilayer structure. Ocher absorbs, stores and releases large amounts of far-infrared rays of sunlight into sponge-like holes.

In addition, ocher is a porous material, and has a high ability to adsorb fine dust, bacteria, and odors due to its high specific surface area. Such ocher is 45-55 wt% silicon dioxide, 20-30 wt% alumina, 10-20 wt% iron trioxide, 1.0-2.0 wt% titanium dioxide, 1.0-2.0 wt% magnesium oxide, 0.0-0.5 wt% calcium oxide, It is preferable to include 0.05-0.15% by weight of sodium oxide and 1.5-2.0% by weight of potassium oxide, and if the content of loess obtained in nature is less than this, necessary ingredients may be added and used.

Ocher has a particle size of 180-250 mesh, preferably 200-230 mesh. In this case, when the particle size is less than 180 mesh, it may be decomposed into water to reduce the strength of the bio-ceramic filter. When the particle size is larger than 250 mesh, far infrared emission may be reduced and the specific surface area may be reduced.

Ocher is used 90 to 99 parts by weight, preferably 91 to 98 parts by weight. At this time, when the content of ocher is less than 90 parts by weight, the strength and the ability to remove harmful pollutants may be lowered. When the content is more than 99 parts by weight, the bio-ceramic filter 550 may not maintain the shape during molding.

The chamotte is already calcined at 1450 ° C. and when the chamotte is added, the chamotte can be used to maintain the shape of the bio-ceramic filter only by the drying process. The bio-ceramic filter 550 of the present invention can maintain the molded shape only with the plastic clay and the loess, but if the chamotte is added, the molded shape is more firmly maintained.

The chamotte is 50-60% by weight of silicon dioxide, 30-37% by weight of alumina, 1-5% by weight of iron trioxide, 1-5% by weight of titanium dioxide, 0.1-2.0% by weight of magnesium oxide, 0.01-0.1% by weight of calcium oxide, It is preferable to include 0.01-0.1 wt% sodium oxide and 0.1-2.0 wt% potassium oxide.

The bioceramic filter 550 of the present invention is manufactured in a plate or granule shape.

In addition, the bio-ceramic filter 550 is not only calcined, but also excellent in strength only by drying after molding without firing, as in the case of manufacturing ceramics in the past, and does not perform a calcining process so that enzymes and microorganisms are still alive. Since the bio ceramic filter 550 is porous, the antibacterial and deodorizing effects are excellent, and since a large amount of far infrared rays are emitted, a large amount of harmful substances, in particular, VOC is removed.

The air purifier according to the present invention not only removes odors and dusts contained in the air of an industrial field, but also improves the efficiency of removing VOCs, which are particularly harmful substances, thereby improving the working environment.

As described above, although described with reference to a preferred embodiment of the present invention, the present invention can be variously modified or modified without departing from the spirit and scope of the present invention described in the claims Those skilled in the art will appreciate.
