By adding a catalyst, maturing and filtering the mixture, coating or applying it to a non-woven fabric and heat-treating it, the adsorption amount of heavy metals and carbon dioxide can be improved as well as antibacterial properties. The adsorption and antibacterial mixture coated or applied to the non-woven filter can be By having antiviral and adsorption properties, it antibacterializes and deodorizes the air sucked into the air conditioner and supplies only purified air to the air conditioner, thereby safely supplying heated or cooled air to the room. It also removes water glass and odors from silica crushed by a grinder.

By transplanting and cultivating Dunaliella salina in the Dunaliella salina culture medium composition optimized for the culture of Ela salina, it not only increases the growth rate of Dunaliella salina, but also absorbs heavy metals and carbon dioxide that can increase the content of beta-carotene. and a method of manufacturing a non-woven filter for an air conditioner or heater having an antibacterial function, and a technology related to a nonwoven filter for an air conditioner or heater manufactured by the manufacturing method.

An air conditioner is a concept that includes a cooling device (air conditioner) that cools and circulates air, and a heating device (heater) that heats and circulates air. A circulation fan is usually installed inside the main body, which has an inlet and an outlet, and provides an inlet. It sucks in indoor air through the main body, cools or heats the inhaled air, and then discharges it back into the room through the outlet.

Usually, air conditioning and heating devices are manufactured and sold as separate products, but recently, cooling and heating devices that can simultaneously cool and heat as a single device are being used. The air conditioner used in this specification may be understood as a concept including an air conditioning device, a heating device, and an air conditioning device.

A detachable filter is built into the intake port inside the main body of such an air conditioner to filter out foreign substances such as dust included in the inhaled air. This filter is usually in the form of a mesh net or net made of plastic (PP).

Recently, as interest in indoor air quality has increased, precision filters (such as HEPA filters or nano filters) used in air purifiers are used in air conditioning and heating devices. However, in this case, the cost is high and there is a hassle of cleaning or replacing the filter. Therefore, it is common to purchase and use a separate air purifier.

Meanwhile, in Republic of Korea Patent Publication No. 10-2020-0018762 (2020.02.20), which is a prior art, an external filter attached to the outer surface of the intake port of an air circulator is disclosed. This external filter has multiple filter members such as a HEPA filter or activated carbon filter. It is closely provided on the inner surface of the suction hole of a plate-shaped support member where the suction hole is formed or on one side of the support member by heat fusion, etc., and has a structure in which an adhesive is provided on the other side of the support member (the side facing the suction port). there is.

However, this prior art uses a relatively expensive filter member such as a HEPA filter or activated carbon filter, and the filter member must be fixed to the support member by heat fusion or the like, which has the problem of increasing manufacturing costs.

In addition, since the plate-shaped support member is applied, it can be relatively easy and sturdy to attach to a stand-type air conditioner, but when applied to a wall-mounted air conditioner with a curved shape of the inlet, it may be difficult to attach and may not be sturdy.

Meanwhile, Dunaliella salina, a natural microalgae, is a eukaryotic organism belonging to the green algae that performs photosynthesis, and can survive in salt concentrations ranging from about 1/10 of seawater to 5M, which is close to a saturated solution. It exhibits high salt adaptability characteristics. Therefore, Dunaliella salina is mainly found in places with low nitrogen content, strong sunlight, and high salt concentration.

In addition, Dunaliella salina contains natural beta-carotene. When the culture environment deteriorates, such as when exposed to strong light, beta-carotene is synthesized in large quantities to protect chlorophyll a, an important chlorophyll for photosynthesis, and is stored under the cell wall. It is known to form a beta-carotene film. These cells accumulate beta-carotene (β-Carotene) and become yellow-green to orange-colored. Therefore, these two Naliella salinas are known as marine microalgae that can be used for various purposes such as health foods and medicines.

Beta-carotene (β-Carotene) accumulated by the Dunaliella salina is a carotenoid-based red pigment and is contained in large quantities in green leafy vegetables such as red carrots and tomatoes. Beta-carotene is added to and used in foods due to its unique color and efficacy, and is widely used as an anticancer agent, antioxidant related to skin aging, skin disease treatment, and antibacterial agent.

however. Despite the usefulness of beta-carotene, mass production is difficult and its content is limited even in green leafy vegetables, making production difficult.

Recently, research is being conducted to utilize Dunaliella salina and beta-carotene for various purposes such as health foods and medicines. Accordingly, methods for cultivating Dunaliella salina and methods for separating and purifying beta-carotene from Dunaliella salina There are many reports about this.

Therefore, the mixture of rice husk liquid, silica mixture, and Dunaliella salina powder is extracted, a catalyst is added, aged, and the filtered mixture is coated or applied to non-woven fabric and heat treated to improve the adsorption amount of heavy metals and carbon dioxide as well as antibacterial properties. Since the adsorption and antibacterial mixture coated or applied to the non-woven filter has antiviral and adsorption properties, it antibacterializes and deodorizes the air sucked into the air conditioner and supplies only purified air to the air conditioner, thereby safely keeping the heated or cooled air indoors. It can be supplied to silica pulverized with a grinder, mixed with water glass and phytoncide solution for odor removal, fried in an industrial microwave like fried rice to make it porous, and then added with calcium carbonate and red clay to make a silica mixture. It can improve the adsorption of heavy metals and carbon dioxide, and the components that can increase the content of beta-carotene (β-Carotene) contained in Dunaliella salina include KNO ₃ , KH ₂ PO ₄ , and FeSO ₄ ·7H ₂ 0 and MnSO ₄ ·H ₂ 0 The growth rate of Dunaliella salina is increased by transplanting and culturing Dunaliella salina in a Dunaliella salina culture medium composition optimized for the culture of Dunaliella salina prepared by adding MnSO 4 ·H 2 0 Of course, there is an urgent need for the development of a method for manufacturing a non-woven filter for air conditioners and heaters that can increase the content of beta-carotene and has heavy metal and carbon dioxide adsorption and antibacterial functions, as well as a non-woven filter for air conditioners and heaters manufactured using the manufacturing method.

The functions of the technical steps constituting the method of manufacturing the non-woven filter for air conditioners and heaters with heavy metal and carbon dioxide adsorption and antibacterial functions are as follows.

First, a step (S1) of manufacturing a nonwoven fabric by carding, cross-lapping, and needle-punching the single fibers of the composite fibers, which includes composite fibers including polyethylene terephthalate (PET) fibers and low melting point fibers. Nonwoven fabric is manufactured by carding, cross-lapping, and needle-punching single fibers.

Here, since the conventional technology for producing nonwoven fabric by carding, cross-lapping, and needle-punching the short fibers is well known, detailed components and methods will be omitted.

At this time, the short fibers include polyethylene terephthalate (PET) fibers and low melting point fibers. The polyethylene terephthalate (PET) fibers have a melting point of 260°C, and the low melting point fibers have a melting point of 260°C. It is 110℃.

In addition, the composite fiber is made of polyethylene terephthalate (PET) fiber and low melting fiber at a mixing ratio of 8:2.

The needle punching consists of a pre-punching machine and a main punching machine, and is performed in one direction perpendicular to the web. The main stroke number of the needle punching is 1000 to 1400 (stroke/min), preferably 1200 (stroke). /min).

The nonwoven fabric produced by step (S1) has a weight of 60 to 80 g/m, preferably 65 to 75 g/m, more preferably 68 to 72 g/m, and most preferably 70 g/m.

The density of the nonwoven fabric is 60 g/m to 80 g/m.

Second, in the step (S2) of preparing rice husk liquid, impurities present on the surface of the rice husk are removed, the rice husk is heated to carbonize, and then the rice husk liquid is liquefied to prepare a rice husk liquid.

Here, rice husk liquid is obtained by heating and carbonizing rice husk and then liquefying it. The main raw material, rice husk, is the husk or outer husk of rice and is also called maejomit bran. When rice husk goes through the carbonization process, it creates countless pores like fine honeycombs, the surface area of which is more than 200 pyeong per gram, and because it is in the shape of the rice husk itself, it has excellent adsorption and breathability. Additionally, because it has a dense structure and many pores, it selectively absorbs harmful substances. In other words, as the cell wall of rice husk burns, numerous microscopic pores are created, and these pores can function to selectively absorb harmful viruses or toxins by exerting strong adsorption.

In addition, the rice husk can be prepared by removing impurities such as dirt, sand, stone dust, etc. present on the surface by spraying air or washing it with running water several times so as not to affect the carbonization and liquefaction process, which will be described later. It may be prepared by grinding with any equipment selected from a ball mill, attrition mill, jet mill, rotary mill, and vibration mill. will be.

In addition, the rice husk from which impurities have been removed can be heated to 600-1000 ℃, preferably 750-850 ℃, to carbonize the rice husk to remove the lignocellulose such as cellulose. If the carbonization temperature is less than 600 ℃, cellulose, which is a cellulose, can be carbonized. It may be difficult to remove, and if the temperature exceeds 1000 ℃, the mineral components may be denatured.

In addition, the carbonized rice husk can be liquefied by applying pressure, preferably 5KG, under conditions of 50 to 300 ℃, preferably 100 to 200 ℃. If the temperature is less than 50 ℃, it may be difficult to extract the active ingredients. Also, if the temperature exceeds 300°C, it is undesirable because the active ingredient may be denatured by heat.

Thirdly, in the step (S3) of preparing a silica mixture by adding calcium carbonate and red clay to silica, water glass and a phytoncide solution for odor removal are added to silica pulverized with a grinder, and then fried like puffed rice using an industrial microwave oven. After frying to make it porous, calcium carbonate and red clay are added to produce a silica mixture, so the adsorption of heavy metals and carbon dioxide can be improved through porosity.

Fourth, in the step (S4) of transplanting and culturing Dunaliella salina in the Dunaliella salina culture medium composition, the saline water is pretreated by sterilizing or filtering, the temperature of the saline water is adjusted to 25 to 35°C, and then 1L of saline water is added. for KNO ₃ 8x10 ^-4 to 11x10 ^-4 g; KH ₂ PO ₄ 6x10 ^-5 to 9x10 ^-5 g; FeSO ₄ ·7H ₂ 0 7x10 ^-6 to 10x10 ^-6 g; and MnSO ₄ ·H ₂ 0 1x10 ^-6 to 3x10 ^-6 g; SiO ₃ 2.0x10 ^-6 to 3.0x10 ^-6 g; C ₁₂ H ₁₇ N _4O S 9.0x10 ^-7 to 10.0x10 ^-7 g; And Dunaliella salina is transplanted and cultured in a Dunaliella salina culture medium composition prepared by adding 3.0x10 ^-8 to 4.0x10 ^-8 g of C ₆₃ H ₈₈ CoN ₁₄ O ₁₄ P.

Here, Dunaliella salina is a eukaryotic organism belonging to photosynthetic green algae, and is a unicellular green algae with a cell volume of 50 to 100 mm3. Their cells are surrounded by a thin, elastic mucous membrane and do not have a hard polysaccharide cell wall like that of other plants. Dunaliella salina is known to contain a large amount of beta-carotene, and when the culture environment deteriorates, such as irradiation with strong light, beta-carotene is synthesized and stored under the cell wall to protect chlorophyll A, an important chlorophyll for photosynthesis. It is known to form beta-carotene membranes. Beta-carotene, known as the main ingredient of Dunaliella salina, is not only used as a dye, but is also known to have antioxidant and anti-cancer effects, so it is used in food, cosmetics, and medicine.

Fifthly, in the step (S5) of manufacturing Dunaliella salina powder, the cultured Dunaliella salina culture medium was treated with 70% ethanol, the extract extracted at room temperature was filtered, and the obtained filtrate was placed in a vacuum concentrator. Dunaliella salina powder is prepared by removing the solvent and freeze-drying.

Sixth, the step (S6) of preparing a mixed solution of rice husk liquid, silica mixture and Dunaliella salina powder, the rice husk liquid and silica mixture prepared in steps (S2), (S3) and (S5). and Dunaliella salina powder are mixed and stirred to prepare a mixed solution.

The rice husk liquid prepared in step (S2), the silica mixture prepared in step (S3), and the Dunaliella salina powder mixed in a weight ratio of 1: 1 to 3: 1 to 4, preferably. Preferably, the mixture is mixed at a weight ratio of 1:1.5:2 and then stirred at 20 to 40 RPM, preferably 25 to 35 RPM, for 12 to 36 hours, preferably 20 to 30 hours.

Seventh, a step (S7) of extracting the mixed solution and then maturing it by adding a catalyst, which involves extracting the mixed solution and then maturing it by adding a catalyst selected from platinum, alumina, iridium, and silver.

Here, the mixed solution prepared in step (S6) is extracted into a high-pressure liquid phase using any equipment selected from a heating stirrer, a high-temperature pressurizer, and an extruder (pressure molding machine), and then a catalyst is added and the mixture is extracted for 1 to 3 days, preferably 2. It can be aged for one day.

As the catalyst, any one of platinum, alumina, iridium, or silver can be used, preferably a silver catalyst.

The eighth step is to filter the mixed liquid (S8), which involves filtering the mixed liquid by passing it through a filter medium.

Here, rapid filtration, slow filtration, filtration using sterilized gauze, paper filter, or glass filter, or high-speed rotation separation using a centrifuge, etc., in which the mixed solution aged in step (S7) is passed through a filter medium at a speed of 120 to 200 m. Filtration can be performed by selecting one method.

Ninth, in the step (S9) of coating or applying the mixed solution to the non-woven fabric and heat treatment, the filtered mixed solution is coated and heat-treated on the non-woven fabric prepared in step (S1).

Here, when the mixture of Dunaliella salina powder was coated or applied to the nonwoven fabric, carbon dioxide (CO ₂ ) was reduced from 6800 ppm to 500 ppm, and also when coating the powder containing the catalyst added in step (S7) Although the efficiency is slightly lower than the ball type, there is no significant difference in commercialization. As shown in Figures 2 and 3, it can be used in various forms by applying it for catalyst powder type and ball type filling, and as a result of experiments, In high concentration areas such as parking lots, 13,000 ppm was reduced to 800 ppm, and in homes and confined places, 2,000 to 3,000 ppm was reduced to less than 500 ppm.

The tenth step is to cut the non-woven fabric (S10), in which the heat-treated non-woven fabric is cut to fit the product to be used.

Here, the cutting is to manufacture the nonwoven fabric into a desired shape and size, for example, it can be cut into a square shape and a size that can cover the intake port of a stand-type air conditioner.
