The equipment body case 100 is fixed by a base plate 101 with a moving wheel 103 supporting the body and a connecting structure 104 for connecting the top plate 102 and the inner unit 200 is intake air. The ceramic supporting the dispersion plate 201, 202, 210, 220, 230, the porous ceramic dielectric 20 and the dielectric ceramics formed with a plurality of air dispersion holes so as to stay for a longer time to increase sterilization power The connecting rod 30 and the ceramic connecting nut 31 are configured, and a fan 300 and a driving motor 301 are installed at the bottom to suck the indoor contaminated air 500 into the equipment.

At the bottom, a filter set 400 in which a pre-filter capable of filtering insects, insects, and fine dust in indoor air, and a medium filter and a hepa filter are integrated. In order to sterilize viruses and bacteria in the air in a certain space by oscillating microwaves, a magnetron 60 capable of generating microwaves, a high-voltage power source 40 and a waveguide 50 are required, and indoor air passes through the equipment. In the space, a mesh structure composed of a porous ceramic dielectric 20 capable of absorbing microwaves more efficiently is provided so that microwaves are more efficiently absorbed into the dielectric.

In order to propagate the microwaves into the space through which the air is passed, the structure of the waveguide 50 is designed so that the loss of the generated microwave energy is transferred to the sterilization space.

When 2.45GHz microwave is generated from the magnetron by the high voltage applied to the magnetron, and the microwave is output through the waveguide into the air sterilizer, the virus and bacteria adsorbed to the porous dielectric ceramic pores are sterilized by the dielectric heating or the vibration of the microwave The indoor structure 500, which is contaminated by the DNA structure being destroyed by the frequency, is sterilized while passing through the microwave air sterilizer to supply the purified air 600 to the room again.

In order to sterilize the introduced air more effectively, the porous dielectric ceramic array is arranged in a zigzag form as shown in FIG. As it is formed, the sterilization effect is maximized.

4 is a structure in which the porous dielectric ceramic plates are manufactured separately and then fastened, and the pipe 30 and the nut 31 connecting each dielectric ceramic plate are made of a ceramic material so that thermal deformation due to microwaves does not occur. It was.

FIG. 6 shows the sterilization by the microwave 700 introduced into the duct through the waveguide 50 while the porous ceramic dielectric structure is inserted into the air conditioning redt 800 and the contaminated air 500 flowing into the duct passes through the duct. The porous dielectric ceramic is made to be a structure that is discharged and is easily inserted into the duct so that the porous dielectric ceramic structure module 200 is inserted into the porous dielectric ceramic structure module after removing a portion of the duct to be inserted.

Virus and bactericidal apparatus using a microwave according to a preferred embodiment of the present invention is the size of viruses and bacteria contained in the air is 0.005㎛ to 0.05㎛ size for viruses and 0.3㎛ to 30㎛ size for bacteria The porous dielectric material structure is formed so that the pore size is between 5 μm and 100 μm so that the bacteria can be sufficiently captured and adsorbed. Viruses and bacteria attached to the ceramic dielectric process can be sterilized by being instantaneously heated by absorbed microwaves.

The present invention provides a porous ceramic dielectric material 20 in the sterilization region such that the contaminated indoor air 500 sucked to sterilize viruses and bacteria contained in the indoor air is delayed as much as possible in the sterilization region where microwaves are concentrated and the residence time is long. Is a virus and bacteria sterilization apparatus using microwaves formed so that the virus and bacteria adsorbed to the dielectric ceramic pores by zigzag form can be sterilized by instantaneous heating by the microwave 700 absorbed into the dielectric. In order to make the indoor air stay in the sterilization zone as much as possible, the plate or mesh structure 201, 202 where a plurality of holes are processed is placed at the inlet and the outlet side of the sterilization zone so that the indoor air is dispersed and vortices are generated. This hole is configured to reduce and the plurality of holes are circle 210, rectangle 220 of FIG. It was to consist of a wire mesh (230) type. In order to ensure that viruses and bacteria present in the inhaled contaminated indoor air adhere to the ceramic dielectric pores, the porosity of the ceramic material is maintained between 30% and 60% of the total volume and the pore size is evenly distributed in the range of 5 to 100 μm. The ceramic dielectric is distributed in the sterilization area of the sterilizer. The dielectric constant of the ceramic dielectric absorbs microwaves after the virus and bacteria in the inhaled contaminated indoor air adhere to the pores. Viral and bacterial sterilization devices configured to intersect.

When microwave is applied to the dielectric, the power loss value P of the dielectric can be expressed as follows.

here,

f: frequency (Hz)

E: intensity of electric field (v / m)

ε _r : relative dielectric constant

tanδ: tangent loss

Therefore, if the relative dielectric constant and tangent loss value or the electric field strength is large at the same frequency, the power loss value of the dielectric material is increased, thereby heating by the dielectric power loss.

The present invention inserts a porous dielectric mesh in the middle region of the space where air passes, so that viruses and bacteria in the air are adsorbed to the pores, and when the microwave is generated in the adsorbed pores, the dielectric is instantly heated by the dielectric power loss. Viruses and bacteria were allowed to sterilize.

In the method of manufacturing a porous ceramic dielectric, titanium dioxide (TiO2) and calcium titanate (CaTiO3) were used as dielectric ceramic raw materials when the dielectric constant was 100 to 150, and barium titanate (BaTO3) as the dielectric ceramic raw material when the dielectric constant was 1000. 3% of Bi2 (SnO3) 3, a secondary mixture of bismuth dioxide (Bi2O3) and tin dioxide (SnO2), was added to 97% and the dielectric constant was 2000. 5% of Bi2 (SnO3) 3, a secondary mixture of bismuth dioxide (Bi2O3) and tin dioxide (SnO2), mixed at a ratio of 3: 9 to 97% of barium (BaTiO3), was used. 3% of Bi2 (SnO3) 3, a secondary mixture of bismuth (Bi2O3) and tin dioxide (SnO2) in a ratio of 3: 9 to 97% of calcium titanate (CaTiO3) and 97% of titanium dioxide (TiO2) as a ceramic raw material The addition was used. In order to give porosity to dielectric ceramics, polymethyl methacrylate (PMMA) and graphite are added at 5 to 30% and 1 to 5%, respectively, in the range of 1000, 150, 1000, 2000, and 3000. By firing at 1300 ° C. for 2 hours, the porosity was maintained at 30 to 60%, and the pore size was maintained at 5 to 100 μm.

In this case, the firing temperature is different according to the dielectric constant. Therefore, when the dielectric constant is 100 to 150, the firing temperature is set to 1300 ° C. The firing temperature is set to 1400 ° C when the dielectric constant is 1000. The firing temperature is set to 1000 ° C when the dielectric constant is 2000. When the dielectric constant was 3000, the firing temperature was 1320 占 폚.

When polymethyl methacrylate (PMMA) and graphite are added, the particle size can be adjusted differently depending on the desired porosity and pore size.

In the case of the porous ceramic dielectric formed by such a process, the mechanical strength becomes weak due to the pores formed therein, so that when forming, the porous layer 80 and the non-porous layer 70 are alternately formed as shown in FIG. 3. This prevented the mechanical strength of pore formation from lowering.

In other words, in the case of the layer fired without porosity, polymethyl methacrylate (PMMA) and graphite are fired at high temperature without addition of graphite, and in the case of the layer having many pores, the porosity is 30 to 60% of the pore size. It is a ceramic fired at high temperature by adding 5 to 30% and 1 to 5% of polymethyl methacrylate (PMMA) and graphite to form 5 to 100㎛, respectively. After laminating alternately, it was bonded by applying a pressure of 10 to 100kg / ㎠ and fired in a high-temperature electric furnace to alternately fire the layers without pores and the layers with pores alternately to compensate for the mechanical strength of the porous ceramic dielectrics having weak mechanical strength. .
