FIG. 7 is a view illustrating a case where one or more filter units of an air purifier using the photocatalytic zeolite filter according to another embodiment of the present invention are coupled to each other by forming a connection unit 300 between the filter unit and the filter unit. .

8 is a view showing another configuration in the case of combining at least one filter unit of the air purifier using a photocatalyst zeolite filter according to another embodiment of the present invention.

The manufacturing method and features of the photocatalyst zeolite filter constituting the filter unit of the air purifier using the photocatalyst zeolite filter of the present invention will be described in detail as follows.

FIG. 9 is a schematic diagram of a zeolite combined with a photocatalyst constituting a filter unit of an air purifier using a photocatalyst zeolite filter according to an embodiment of the present invention.

As shown in FIG. 9, the bonding structure with titanium dioxide that does not block the pores of the zeolite is made, which is adjustable to 6-7 Å (angstrom) as an inorganic material in which the pore size is controlled, and is 6-7 Å. (Angstrom) It can also manufacture more or less.

The pore of the zeolite 10 is smaller in size than the titanium dioxide 20 so as to have a structure that is stably bonded to the binder 30.

As described above, the adsorptive decomposition performance may be optimized when the nano bond structure is stable.

Said binder preferably uses SiO2.

It creates a bonding structure of titanium dioxide that does not block the pores of the zeolite.

By omitting this process, zeolite, photocatalyst, binder and pulp and other materials can be added and stirred to make a slurry, but this method does not guarantee that the photocatalyst and zeolite are selectively combined first, and the photocatalysts or zeolites are bundled together. There are many cases. In addition, since the zeolite and the photocatalyst are not structurally bound, the zeolite and the photocatalyst are likely to be separated from each other during use.

Nanoparticles of inorganic or metals such as titanium dioxide, zeolite and silica (SiO2) result in changes in catalytic function and enhancement of activity selectivity.

In general, the effect of the smaller particles is the ideal energy level is formed by the quantum size effect due to the increase in the proportion of the surface atoms in the total atoms, the limited range of interaction between atoms.

There are physical and chemical methods of making nanoparticles, and physical methods are advantageous for making various things, and chemical methods reduce ions to atoms and aggregate them to make nanoparticles at once. It can be made uniform.

The titanium dioxide receives energy higher than its bandgap energy (3.2 eV in anatase crystals) to form an electron-hole pair (i.e., generate a polarization state), thereby exhibiting a photocatalytic action.

In addition, it is known that photocatalytic efficiency can be improved by supporting a metal such as silver on a material (TiO2 fine particles) which functions as a photocatalyst. In other words, the electrons and holes in the polarized state have a very short lifespan, and may be recombined and extinguished again before redoxing the external substance (before exerting a photocatalytic action). This extinction (reduction of electrons and holes) is a major factor in lowering the reaction efficiency of the photocatalyst material.

10 is an air filter using a photocatalyst zeolite filter according to an embodiment of the present invention.

It is a bond degree of the zeolite to which the photocatalyst which comprises the filter part of a fire apparatus is couple | bonded.

As shown in FIG. 5, the size of volatile organic compounds (VOCs) is usually 3-4 Å (Angstrom), so that the pore sizes of zeolites are decomposed to adsorb these volatile organic compounds and slowly desorb to decompose the titanium dioxide photocatalyst. 6 to 7 크게 (ang strong) should be somewhat larger.

In other words, since the pore size and structure of the conventional activated carbon filter are not constant as shown in the drawings, the selective adsorption is impossible and the moisture adsorption property is high. Therefore, the pore size is limited. However, the filter of the present invention has a pore size. Since the photocatalyst decomposes the adsorbed volatile organic compounds to empty the pores, the adsorption of new volatile organic compounds becomes possible.

In other words, since zeolite is made by synthesizing, selective adsorption is possible, but activated carbon filters have a large pore size of 200 to 500 Å (Angstrom) and a small pore size and structure do not adsorb small volatile organic compounds. There is a problem that flows, the harmful gas adsorbed is easily desorbed by a small impact or strong wind, there is a problem that the photocatalyst is released even before decomposing, there is no selective adsorption.

FIG. 11 is a schematic diagram of harmful gas filtration of a photocatalytic zeolite filter and a conventional activated carbon filter, which constitute a filter unit of an air purifier using a photocatalyst zeolite filter according to an embodiment of the present invention.

12 is a performance comparison table of the photocatalyst zeolite filter and the conventional filter constituting the filter unit of the air purifier using the photocatalyst zeolite filter according to an embodiment of the present invention.

As the filter shown in Fig. 12 is a nonwoven filter and a urethane filter, these filters are not capable of selective filtration and have poor adsorption performance, and because they do not regenerate themselves because they are not photodegradable, the performance is reduced as shown in the graph. Periodic exchanges will be necessary.

On the other hand, referring to the comparison table of moisture adsorption rate according to humidity, activated carbon is highly affected by humidity, so in a high humidity environment, the adsorption of moisture is blocked first, so there are no pores to adsorb harmful gases. Other devices will be needed.

13 is an air filter using a photocatalyst zeolite filter according to an embodiment of the present invention.

It is a flowchart regarding the manufacturing method of the photocatalyst zeolite filter which comprises the filter part of a chemical conversion apparatus.

As shown in Figure 13, the photocatalyst zeolite filter manufacturing method,

Adding a zeolite powder, a titanium dioxide powder, and a binder, mixing, stirring, and baking to combine the photocatalyst (S100);

Mixing the zeolite and the photocatalyst with water, pulp, ceramic fiber, glass fiber, and binder to make a slurry;

A sheeting step (S110) of homogenizing the slurry on a plate and forming a sheet by evaporation;

A waveform wave form step (S120) of waveform wave form to increase the surface area;

Laminating step (S130) for bonding using an adhesive between the sheet and the sheet;

Cutting step (S140) of cutting the lamination is completed to a suitable size;

And a second step of coating and drying the photocatalyst to increase photoactivity on the cut surface.

Combining the photocatalyst,

First, the zeolite powder and the photocatalyst powder are stirred and mixed for a while, and then an appropriate amount of water is added to the mixture to be stirred and mixed to completely mix the zeolite, the photocatalyst, and the water. After preparing a slurry in which the zeolite and the photocatalyst are mixed, the slurry of the photocatalyst zeolite is dried until about 1/4 of water is left, and a binder (SiO2) is added thereto, followed by stirring and mixing. Thereafter, stirring and mixing are performed while gradually raising the temperature of the slurry to form a slurry including a zeolite / binder / photocatalyst. In the process of raising the temperature, the zeolite is formed to stably surround the photocatalyst by the core / shell effect described later, and the binder serves as a support for more stably maintaining the core / shell structure of the photocatalyst and the zeolite. And the temperature is heated to 200 ~ 250 degrees to dry. In this way, if the zeolite layer is formed differently on the surface of the titanium dioxide, it is possible to obtain a stable structure in which the titanium dioxide photocatalyst is nano-structured on the surface of the zeolite.

Zeolite may be used in the size of 20nm to 2000nm for the stable coupling with the photocatalyst, but preferably 30 to 50nm.

In the photocatalyst slurry, the anatase type fine particles are simply dispersed in the aqueous medium.

The generation mechanism of hetero nanoparticles having a titanium dioxide / zeolite structure is described as follows.

First, titanium dioxide particles and zeolite particles are coordinated with silica as a binder.

At this time, when heated, titanium dioxide nanoparticles are formed, and when heated continuously, zeolite particles are precipitated on the titanium dioxide nanoparticles to form a zeolite shell.

This forms a core / shell structure due to the difference in the redox potential of titanium dioxide and zeolite, and because the zeolite particles are strongly coordinated with silica, they cannot move freely, but the titanium dioxide nanoparticles are relatively weakly coordinated. This is because titanium dioxide nanoparticles can easily gather and form clusters.

When clusters of titanium dioxide particles are formed, zeolite nanoparticles gather around them.

Zeolite is an inorganic material in which the pore size is controlled, and the pore size can be adjusted to 6-7 Å (Angstrom) and can be manufactured to 6-7 Å (Angstrom) or more. Since the size of volatile organic compounds (VOC) is 3 ~ 4 Å (Angstrom), the size of zeolite pores should be somewhat larger.

The synthesis of the zeolite is synthesized by hydrothermal synthesis.

Hydrothermal synthesis method is a synthesis method of a substance performed in the presence of water at high temperature and high pressure, and zeolite is synthesized using this synthesis method. Raw materials for synthesizing zeolites generally include silica, alumina, mineralizers (alkali, alkali, fluoride) and water.

Si and Al are components constituting the zeolite skeleton, and the mineralizer plays a role in dissolving such metal components in water. In addition, the cation contained in the mineralizer also serves to remove the negative charge of the skeleton finally.

When synthesizing a large high silica zeolite of Si / Al, a large volume organic compound is added as a structural regulator. The raw materials are mixed to prepare a highly reactive amorphous hydrogel, which is placed in an autoclave and heated at a predetermined temperature (˜250 degrees) to generate zeolite.

Since the zeolite is obtained almost as a metastable phase, the synthesis is influenced not only by the temperature and the composition of the raw material but also by various factors such as the type of raw material, mixing method, pH, stirring method and reaction vessel.

In order to obtain a zeolite having a structure and properties suitable for the purpose, it is necessary to appropriately select the above synthesis conditions. After synthesis, ion exchange can be performed to control more detailed structures and properties.

The zeolite can be controlled in size because it is synthesized, but the activated carbon is 500 Å (angstrom), which is too large compared to organic compounds (VOC), so the adsorption efficiency is lowered, and the surface area that can be adsorbed is per unit area. Smaller than zeolite.

The sheeting step,

The zeolite mass combined with the photocatalyst, which turns into a solid solid, is broken up into powder. At this time, the mixed photocatalyst coated zeolite structure powder, pulp powder, and binder are mixed with distilled water.

The ratio of the structure powder, pulp powder, and binder is preferably 4: 8: 1, and the mixed powder and distilled water are mixed at a ratio of 1: 1.

The powder turned into a thin gel is called a slurry.

The sheet is prepared by homogenizing the slurry on a shaped plate and then allowing it to evaporate at room temperature.

Evaporate the moisture at room temperature until the sheet reaches 15% moisture. The sheet containing about 15% moisture is corrugated.

The waveform step,

Corrugating the sheet is intended to maximize the surface area in a small area by rolling the sheet in a snaky way. In addition, it is to ensure space between the sheets when the sheets overlap.

An example of a corrugated sheet is understood by looking at the cross section of a thick box. The waveform step of the present invention is also completed on the same principle by placing a rather moisture-containing sheet into a waveform press and applying heat.

The corrugated sheets may be rolled up like paper without being stacked. At this time, the length of the horizontal can be varied, but 60cm is suitable, and the diameter can be made in various sizes as needed, but 10 ~ 60cm is suitable.

The cutting step,

The laminated sheet is cut to an appropriate size. For example, it can be cut into squares having a width of 30 cm and a length of 30 cm and a thickness of 1 to 3 cm, and can be cut to various thicknesses depending on the use, but 1 to 5 cm is suitable for transmitting the ultraviolet light source.

The cut sheet is used as one filter.

Second coating and drying the photocatalyst,

Honeycomb filter cut to a suitable size can be used as a filter as it is, but since the cut surface comes in contact with air first and receives the most ultraviolet rays, the photocatalyst is coated on the cut surface to increase the photodegradation performance. Should go through. In order to coat the photocatalyst on the front face, first, a photocatalyst sol (TiO2 Sol) should be made. As the photocatalyst powder, the anatase structure has a size of 5-25 nm and more preferably 7-10 nm. The powder is dispersed in a water base, and 3 nm size SiO 2 is used as a binder.

The ratio of the photocatalyst and SiO2 is preferably 8: 2 on the basis of wg /%. As a method of coating the photocatalyst sol (Sol) on the cut surface of the honeycomb, there are methods such as spray coating and deep coating, but spray coating is difficult to coat a large amount of powder on the surface, and the dip coating method is a honeycomb after coating The filter is susceptible to deformation and requires a lot of time and energy to dry. Therefore, a roller coating apparatus for designing and realizing a new coating method called roller coating as a method of coating the honeycomb filter is shown in FIGS. 9 to 10.

As shown in Figures 14 to 15, the honeycomb filter passes over a roller with a photocatalyst coating liquid and is coated on one side, and the honeycomb filter is inverted and passed through the first drying line, and then the other side is coated. The coated surface is turned upside down again and the coating is completed by the second drying process. After the coating is completed, the honeycomb is loaded into a drying tray (not shown), transferred to a drying chamber, and dried by hot air to complete the honeycomb.

The finished filter is a titanium dioxide-coated zeolite filter, in which volatile organic compounds having a size of less than 3 kW (on-strong) are preferentially adsorbed into the micropores of the zeolite. Existing activated carbon has a micropore of 500 Å (Angstrom), so the size is relatively larger than volatile organic compounds, so the number of volatile organic compound molecules adsorbed to the activated carbon micropores is limited.

However, since the micropores of zeolite are 6 kW (ang strong) to 30 kW (ang strong) depending on processing conditions, they provide 400-700 times or more micropores to which volatile organic compound molecules can be adsorbed compared to activated carbon per unit area. As a result, the adsorption amount of the volatile organic compound molecules can be increased.

In the zeolite filter applied to the present invention, the volatile organic compounds adsorbed on the zeolite remain in the micropores while being adsorbed for a certain period of time, and then slowly come out around the micropores due to wind or temperature increase, and are decomposed by titanium dioxide around the micropores. do.

Titanium dioxide is a catalyst which does not change itself as a catalyst and is a photocatalyst which decomposes harmful gas molecules and is harmless.

Volatile organic compounds around the micropores are exposed to titanium dioxide and decomposed, and may be irradiated with UV lamps to promote catalysis.

Inorganic adsorption prepared to improve the antimicrobial activity, deodorizing power and adsorption function by using a zeolite, a natural mineral that emits a large amount of far infrared rays, through a special process to obtain a carrier in a slurry state, and then using the titanium dioxide (TiO2) as a photocatalyst. After sufficiently stirring the photocatalyst with a predetermined amount to obtain an inorganic adsorbent in which a slurry photocatalyst is mixed, this method is used to prepare a structure having a zeolite to which a photocatalyst is bound, that is, a photocatalyst zeolite filter by the method of the present invention. To maximize the function.

Those skilled in the art to which the present invention pertains as described above may understand that the present invention may be implemented in other specific forms without changing the technical spirit or essential features of the present invention.
