DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. However, the present invention is not limited to the above, and design changes may be made as appropriate within the scope of the present disclosure. In the following description, the same parts or parts having similar functions are referred to as The same reference numerals are used in common between different drawings, and the repeated explanations are omitted. The configurations described in the embodiments and modifications may be combined or modified as appropriate. In order to facilitate understanding of the description, the configurations of the following drawings are simplified. In some cases, the components are illustrated in a simplified or schematic manner, and some of the components are omitted.

[0014] [First embodiment] (Overall configuration of air purifier 100) FIG. 1 is a cross-sectional view showing the configuration of an air purifier 100 according to the first embodiment.

[0015] The air purifier 100 according to the first embodiment removes dust particles from the air (purifies the air). ) and removes (absorbs and captures) carbon dioxide from the air. The sensor may be installed indoors or outdoors as a standalone device, or may be integrated with other devices (vehicles, aircraft, ships, etc.) The air purifier 100 may be installed outdoors. In this case, it is preferable that the housing 10 of the air purifier 100 is waterproof. If the location is not subject to such a force, the housing 10 does not need to be waterproof.

[0016] (Configuration of each part of the air purifier 100) As shown in FIG. 1, the air purifier 100 includes a housing 10. The housing 10 includes an air intake 11. An exhaust port 12, an opening 13, a maintenance door 14, and wheels 15 are provided. In the first embodiment, the air intake 11 is formed on the bottom surface of the housing 10. The air is introduced from the outside of the housing 10 into the housing 10. The exhaust port 12 is formed on the top surface of the housing 10. The exhaust port 12 exhausts the air inside the housing 10 to the outside of the housing 10. In the first embodiment, the opening 13 is formed on the side surface of the housing 10. Air from outside the housing 10 is introduced into the air path 80. The maintenance door 14 is The door is opened and closed by rotating on a hinge. In the explanation, the horizontal plane is the XY plane, and each direction in the XY plane is defined as X The X1 direction, the X2 direction, the Y1 direction, and the Y2 direction. The up direction is the Z1 direction, and the down direction is the The direction is Z2 direction.

[0017] As shown in FIG. 1, the air purifier 100 includes an absorption unit 20 and an air purification filter. The air conditioner includes a cooler 30, nonwoven fabric filters 41 and 42, a fan 50, and a damper 60.

[0018] The absorption unit 20 is provided with one or more absorption filters 21. In FIG. Although three absorption filters 21 are shown, it is possible to use two or less absorption filters 21 or four or more absorption filters 21. may be provided in the absorption unit 20. For example, the plurality of absorption filters 21 may be arranged vertically. The absorption filters 21 are arranged in the same direction. This allows the manufacturing cost of the absorption filter 21 to be reduced. The filter 21 can be individually removed from the outside of the housing 10 when the maintenance door 14 is opened in the X2 direction. For example, the absorption filter 21 can be removed for maintenance. The door 14 is disposed in the housing 10 so as to be slidable toward the door 14 (in the X2 direction). This allows only the absorption filter 21 that needs to be replaced to be selected from among the multiple absorption filters 21. The number of absorption filters 21 arranged in the absorption unit 20 can be changed or removed. As a result, the absorption filter 21 can be easily replaced. This makes it easier to recycle the absorbing member 21a.

[0019] In the first embodiment, the absorption unit 20 is disposed in the lower part of the housing 10. The absorption unit 20 is arranged above the airflow generated by the fan 50 against the air cleaning filter 30. It is placed on the stream side.

[0020] FIG. 2 is a cross-sectional view showing a schematic configuration of the absorption filter 21. As shown in FIG. The absorption filter 21 is a filter that absorbs carbon dioxide. The device includes an absorbing member 21a for absorbing carbon dioxide, and a case portion 21b for accommodating the absorbing member 21a. The absorbing member 21a is, for example, a hydroxide-based carbon dioxide absorbent. The absorbing member 21a contains a hydroxide that absorbs carbon dioxide through a chemical reaction. When it comes into contact with air, it reacts with carbon dioxide in the air and The material that absorbs carbon dioxide through a chemical reaction is calcium-based. The calcium-based material includes, for example, calcium hydroxide. In addition to the method of using chemical reactions, there is also a method of physically absorbing carbon dioxide without causing a chemical reaction. One method is to adsorb the molecules into the pores of the absorbent material. For example, the molecules are absorbed into a porous material such as zeolite. This method physically adsorbs carbon dioxide molecules onto the absorbent. In this method, carbon dioxide is desorbed from the absorbing member and the desorbed carbon dioxide is converted into a solid. This requires a process to convert carbon dioxide into a solid, increasing the number of processes required. According to the configuration of the first embodiment, a member that absorbs carbon dioxide through a chemical reaction is used. This makes it possible to capture carbon dioxide in a solid (powder) state after it has been chemically transformed. This allows for a second advantage over the method of physically adsorbing carbon dioxide molecules onto an absorbent. Carbon dioxide can be easily reused. For example, sodium hydroxide, magnesium hydroxide, water Ammonium oxide or potassium hydroxide may be contained in the absorbing member 21a. The material 21a has a cylindrical shape, an average diameter Φ of 2 mm or more and 3 mm or less, and a length (height ) is 5.0 mm.

[0021] In addition, when calcium hydroxide is used for the absorbing member 21a, carbon dioxide is added to the calcium hydroxide. By absorbing calcium carbonate, calcium carbonate can be produced. Calcium can be used to create raw materials for a variety of recycled products.

[0022] The absorbing member 21a may contain a dye such as methyl violet. The absorbing member 21a is adapted to change color in response to a change in pH caused by the amount of absorbed carbon dioxide. In this case, for example, when the absorbing member 21a absorbs carbon dioxide, it changes from "white" to The color of the carbon dioxide changes from red to red, purple, or pink. A substance that changes from "red or purple" to "white or pink" upon absorption may be used. However, a color that changes to a color other than those mentioned above may also be used.

[0023] The absorbing member 21a is formed in a granular shape. As shown in FIG. A plurality of absorbing members 21a are arranged in the case portion 21b. This makes it easier to handle than liquid, and the user can easily replace the absorption filter 21. The absorbing member 21a is unlikely to adhere to the person who collects the waste. or formed in a breathable mesh shape. b brings the outside air into contact with the absorbing member 21a in the case portion 21b.

[0024] As shown in FIG. 2, a two-dimensional code 21c is attached to the absorption filter 21. The two-dimensional code 21c is, for example, a QR code (registered trademark). The port 20 may be provided with a one-dimensional code (barcode) instead of the two-dimensional code 21c. Alternatively, an electric circuit capable of storing information, such as an IC chip, may be provided. c can be used as the "two-dimensional code" described in Patent Publication No. 7189644, for example. can be done.

[0025] The air purifying filter 30 is, for example, a filter that captures dust. A HEPA filter can be used as 30. Also, as shown in FIG. The air filter 30 is disposed between the absorption unit 20 and the fan 50. The cleaning filter 30 is disposed downstream ( The absorption unit 20 is temporarily placed in the absorption section 10 (the upper part of the housing 10). Even if a part of the material 21a is released, the absorbing member 21a is captured by the air cleaning filter 30. Therefore, the absorbing member 21a can be prevented from being captured and released outside the air purifier 100.

[0026] The nonwoven fabric filters 41 and 42 have higher breathability than the air purifying filter 30. The nonwoven fabric filter 41 prevents foreign objects and dust from entering the inside of the absorbent unit 20. The nonwoven fabric filter 42 is disposed upstream of the air flow. It is located on the intake side of the

[0027] The fan 50 is driven by the supply of power, and as shown in FIG. Air is drawn into the housing 10 through the opening 13, and the air is expelled from the housing 10 through the exhaust port 12. The fan 50 may be, for example, a sirocco fan, or a propeller fan. In the first embodiment, the power consumption of the fan 50 is When the amount of carbon dioxide converted is converted, the amount of carbon dioxide that can be absorbed by the absorption unit 20 is The fan 50 is used to reduce the amount of carbon dioxide that can be removed. The ventilation path 80) is under negative pressure because the fan 50 is located downstream. The air is not discharged outside the housing 10 without passing through the air cleaning filter 30.

[0028] FIG. 3 is a diagram illustrating a ventilation path from the intake port 11 to the exhaust port 12 according to the first embodiment. As shown in FIG. 3, the housing 10 includes an intake port 11, a nonwoven fabric filter 41, an absorbent Unit 20, damper 60 and opening 13, nonwoven fabric filter 42, air cleaning filter 30 The fan 50 and the exhaust port 12 are arranged in this order from the upstream side of the airflow. This is the air flow generated by driving the fan 50. By driving the device, the intake port 11, the nonwoven fabric filter 41, the absorption unit 20, and the damper 6 0 and an opening 13, a nonwoven fabric filter 42, an air cleaning filter 30, a fan 50, and an exhaust port The airflow A1 flows in the order of the opening 13 (damper 60), the nonwoven fabric filter 42, and the air cleaner 12. An airflow A2 flows through the air filter 30, the fan 50, and the exhaust port 12 in this order. As described above, in the first embodiment, both the airflow A1 and the airflow A2 pass through the air cleaning filter 30. Only the airflow A1 passes through the absorption unit 20. The amount of air passing through the absorption unit 30 can be made larger than the amount of air passing through the absorption unit 20. As a result, the air cleaning function of the air purifier 100 can be improved. In the air purifier 100 of the embodiment, a fan 50 for ventilating the air purification filter 30 and , and the fan 50 for ventilating the absorption unit 20 can be shared.

[0029] As shown in FIG. 1, the housing 10 includes an intake port 11, a nonwoven fabric filter 41, an absorption unit 42, and a filter 43. 20, damper 60 and opening 13, nonwoven fabric filter 42, air cleaning filter 30, The fan 50 and the exhaust port 12 are arranged in this order toward the top.

[0030] The opening 13 is disposed in the air passage 80 between the absorption unit 20 and the air cleaning filter 30. Air is introduced from the outside of the body 10. When the fan 50 is driven, the ventilation path 80 By creating a negative pressure relative to the outside of the housing 310, the housing 10 Air enters the ventilation path 80 from the outside. FIG. 4 shows an example of the rotation of the damper 60. The damper 60 changes the position (angle) of the flap to adjust the width of the opening 13. The opening degree is changed by changing the opening degree of the air passing through the opening 13. The smaller the pressure loss, the larger the pressure loss for the air passing through the opening 13, the smaller the pressure loss. To reduce the "opening degree", for example, a part of the opening 13 is closed by the damper 60. Alternatively, the damper 60 may be moved to a position (angle) that blocks the air flow. In the fourth example, the damper 60 moves from position P2 to position P1. For example, the damper 60 is used to open the opening 13, or the damper 60 is used to control the air flow. For example, in the example of Figure 4, the camera moves from position P2 to position The damper 60 moves to the position P3. Note that, although six dampers 60 are shown in FIG. , the number of dampers 60 may be five or less, or seven or more.

[0031] FIG. 5 is a block diagram of the air purifier 100 according to the first embodiment. The control circuit 70 includes a memory unit 71 and a sheet number sensor 72. The memory unit 71 is a non-volatile The memory unit 71 includes a storage circuit (memory) for storing the absorption frame arranged in the absorption unit 20. The number of filters 21 and the position of the damper 60 are stored in association with each other. For example, the damper 60 is positioned so that the first wind speed, which is the wind speed of the air passing through the absorption unit 20, is The air passing through the air purifying filter 30 is 0.02 m / s or more and 0.15 m / s or less. The secondary wind speed is set to be between 0.3m / s and 0.5m / s. The first wind speed may be a value between 0.02 m / s and less than 0.50 m / s. In this case, the second wind speed is set to be higher than the first wind speed. The second wind speed may be greater than or equal to 2 m / s and less than 0.25 m / s. In this case, the second wind speed is greater than the first wind speed. It is set higher than the speed limit.

[0032] The number sensor 72 is disposed in the absorption unit 20. The number of absorption filters 21 in the set 20 is detected by the number sensor 72. For example, the number sensor 72 is a contact type sensor. The number sensor 72 is a non-contact sensor (optical or magnetic sensor). The number sensor 72 transmits information on the detected number of sheets to the control circuit 70. In this example, the control circuit 70 obtains the number of absorption filters 21 from the number sensor 72. When the number of absorption filters 21 is "3", the control circuit 70 determines whether the damper 60 is in the position P1. In the first embodiment, the damper 60 is driven so as to be disposed in the position shown in FIG. A driving device such as a motor is provided in the filter 60. The control circuit 70 also controls the absorption filter When the number of 21 is "2", the damper 60 is arranged at the position P2. When the number of absorption filters 21 is "one", the control circuit 70 controls the driving of the damper The drive of the damper 60 is controlled so that the damper 60 is disposed at the position P3.

[0033] The information in which the positions P1 to P3 are associated with the number of the absorption filters 21 is used as the air purifier. The maximum number of absorption filters 2 is determined in advance during the design stage of the device 100. 1 is placed in the absorption unit 20 and the air cleaning filter 30 is attached to the housing 10. The fan 50 is operated in the state where the filter is attached. The position of the damper 60 that maximizes the airflow rate of the filter 21 is recorded. The position is associated with the maximum number. Then, the absorption filter 21 is removed from the absorption unit 20. When one filter is removed, the wind speed passing through the absorption filter 21 is increased to the value at which the absorption efficiency of the absorption filter 21 is maximized. The position of the damper 60 that produces the desired airflow is recorded. By repeating this process, the position Information in which P1 to P3 are associated with the number of absorption filters 21 is created.

[0034] The damper 60 controls the amount of air passing through the opening 13 (the amount of air passing through the air cleaning filter 30 The difference between the amount of air passing through the absorption unit 20 and the amount of air passing through the absorption unit 20 can be adjusted. As a result, even if the number of absorption filters 21 in the absorption unit 20 is changed, appropriate airflow can be obtained. Since air is supplied at a high speed, the reaction efficiency of carbon dioxide can be improved.

In the second embodiment, the damper 260 of the air purifier 200 is manually repositioned. The same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment. will be used and the explanation will be omitted.

[0036] FIG. 6 is a block diagram showing the configuration of an air purifier 200 according to the second embodiment. 6 is a diagram for explaining the configuration of a damper 260 according to a second embodiment. The air purifier 200 further includes a control circuit 270. The control circuit 270 is connected to an operation panel (not shown). In response to input operations to the panel, the operation of the fan 50 can be turned on and off, and the fan 50 can be The air volume is increased or decreased, and the damper 260 is not controlled.

[0037] As shown in FIG. 7, a damper 260 is disposed in a housing 210 of the air purifier 200. The damper 260 is displaced by the wind passing through the opening 13 (see FIG. 1). However, the position can be changed manually. The damper 260 is, for example, It moves between positions P1, P2, and P3 shown in FIG.

[0038] In the second embodiment, the housing 210 includes an absorbent filter disposed in the absorption unit 20. A mark 261 is provided that corresponds to the number of the dampers 21 and the position of the damper 260.

The other configurations and effects are the same as those of the first embodiment. It is.

[0039] [Third embodiment] Next, referring to Figs. 8 and 9, the configuration of an air purifier 300 according to a third embodiment will be described. In the third embodiment, the air cleaning filter 330 is more resistant to air than the absorption unit 320. The same configuration as in the first embodiment includes the same The same reference numerals are used and the explanation is omitted.

[0040] FIG. 8 is a diagram illustrating the configuration of an air purifier 300 according to the third embodiment. As shown in FIG. 1, the air purifier 300 includes a fan 350, an air purifying filter 330, and a damper. The housing 310 includes a partition 360, an opening 313, and an absorption unit 320.

[0061] [Measurement results] Next, referring to FIG. 11 and FIG. 12A, the reaction efficiency η The measurement results are explained below. Figure 11 shows the relationship between the wind speed passing through the absorbing material and the reaction efficiency. 12A is a diagram summarizing the measurement results.

[0062] Here, an absorbent material containing calcium hydroxide (Ca(OH)2) as a main component was prepared. The absorbent member has a columnar shape, an average diameter Φ of 2.0 mm, and a length (height) of 5.0 mm. The absorbing portion has a cylindrical shape, an average diameter Φ of 3.0 mm, and a length (height) of 5.0 mm. The absorbent material was prepared. In addition to calcium hydroxide, sulfur trioxide was also used as the absorbent material. Yellow (SO3) is 0.8%~0.9%, magnesium oxide (MgO) is 0.5%, aluminum oxide is It contains 0.2% aluminum (Al2O3) and a small amount of silicon dioxide (SiO2). .

[0063] The prepared absorber with an average diameter of Φ2.0 mm was subjected to shocks of 0.12 m / s, 0.15 m / s, and 0. At wind speeds of 16 m / s, 0.18 m / s, and 0.2 m / s (hereinafter referred to as "passing wind speed v") After air was passed through the mixture for 100 hours, the percentage of calcium carbonate (reaction rate) was measured. The prepared absorbent material with an average diameter of Φ3.0 mm was subjected to shock waves of 0.3 m / s, 0.4 m / s, and 0 The percentage of calcium carbonate when air is passed through the material for 100 hours at a passing speed of v.5 m / s. The reaction efficiency η is the reaction efficiency (in this embodiment, , 100 hours), the percentage of calcium carbonate (reaction rate) when air is passed through it. The weight percentage of calcium carbonate (CaCO3) is calculated by the gas volumetric method using carbon dioxide. Multiply the percentage by 100.09 and divide by 44.01 to get the answer. (In FIG. 11, this is shown as the "actual measurement value.")

[0064] The measured reaction efficiency η of an absorbent with an average diameter of Φ2.0 mm is 0.12 m / s 90% when the passing wind speed v is 0.15 m / s, 88% when the passing wind speed v is 0.16 m / s, 80%, when the through wind speed v is 0.18m / s, 78%, when the through wind speed v is 0.2 In the case of m / s, the reaction efficiency η of the absorber with an average diameter of Φ3.0 mm was 75%. The measured value is 64% when the passing wind speed v is 0.3 m / s, and 0.4 m / s when the passing wind speed v is 0.4 m / s. 60%, and when the passing wind speed v was 0.5 m / s, it was 51%.

[0065] Here, from the measured value of the reaction efficiency η of the absorption material with an average diameter of Φ3.0 mm, the passing wind speed v is 0. The reaction efficiency η at 2 m / s is estimated to be 67%. Therefore, for the same passing wind speed v, In this case, the reaction efficiency η (75%) of the absorbent with an average diameter of Φ2.0 mm is higher than that of the absorbent with an average diameter of Φ3.0 mm. m, the reaction efficiency η of the absorbing material (67%) was found to be greater than that of the absorbing material. The reaction efficiency η when v is 0.2 m / s is estimated by the The increase in reaction efficiency η when the wind speed v is 0.3 m / s was added to the reaction efficiency η at 0.3 m / s. It is something.

[0066] In addition, for the absorption member with an average diameter of Φ2.0 mm, the "estimated value" of "reaction efficiency η" was calculated. The "estimated value" is the value when calcium hydroxide reacts 100% (calcium hydroxide is The weight of calcium carbonate (CaCO3 For example, the weight and moisture content of the absorbent before the reaction are calculated as follows: The weight of the absorbent material before the reaction (referred to as the "dry weight before the reaction") is calculated by subtracting the amount of water from the absorbent material before the reaction. Then, the weight and the amount of water of the absorbent member after the reaction are measured, and the amount of water is calculated from the absorbent member after the reaction. The weight after removing the moisture (called "dry weight after reaction") is calculated. Also, the absorption before reaction Weight when the material has completely reacted (when all calcium hydroxide has turned into calcium carbonate) Calculate the amount of calcium hydroxide (the maximum weight after reaction). 4. The number of moles of calcium carbonate after the reaction is 100, so divide the "dry weight before the reaction" by 7. 4×100 = "Maximum weight after reaction". And "Reaction efficiency η" = "Dry weight after reaction" The reaction efficiency η, calculated as “maximum weight after reaction” / “maximum weight after reaction”, is shown as an estimated value in Figure 11. Each of the estimated values ​​was higher than the actual measured value.

[0067] In FIG. 12A, the passing wind speed v at which the reaction efficiency η was 80% or more is marked with a double circle, and the passing wind speed v at which the reaction efficiency η was 70% or more is marked with a double circle. %, the passing wind speed v is marked as "〇", 50% or more but less than 70% is marked as "△", and less than 50% is marked as "×". As shown in Figure 12A, the passing wind speed v is 0.02 m / s or more and 0.15 m / s or less. When the air flow rate is less than 100%, the reaction efficiency η is highest. If v is 0.02 m / s or more and less than 0.18 m / s, the reaction efficiency is evaluated as "◎" or "〇". It was found that the rate η becomes higher. In addition, when the passing wind speed v is less than 0.50 m / s, "," "〇" or "△", and the reaction efficiency is higher than when the passing wind speed v is 0.50 m / s or more. It was found that the rate η increases.

[0068] In Fig. 11 and Fig. 12A, the reaction efficiency η is shown. The reaction rate is calculated by dividing the reaction rate by the number of air passages. After 00 hours, the reaction rate slows down and the reaction rate saturates (the reaction rate at saturation is called "saturation rate"). As shown in FIG. 12B, for example, the reaction efficiency η ( If the reaction continues at a passing wind speed v where the reaction rate (reaction rate) is 80%, the saturated reaction rate will be 95%. In addition, at the passage wind speed v where the reaction efficiency η (reaction rate per 100 hours) is 60%, In this way, the reaction efficiency η is high at the airflow speed The higher the v, the higher the saturated reaction rate.

[0069] Here, the absorbent material after the reaction is recycled into raw materials for recycled products (glass materials, fertilizer, and cement) etc.), the higher the calcium carbonate content, the more recycled and recycled products Therefore, the passing wind speed v is set to 0.02 m / s or more and less than 0.18 m / s. If the reaction efficiency is less than 70%, the reaction efficiency is 70% or more. In the absorbent filter, the percentage of calcium carbonate is 70% or more. When calcium is used as a raw material for recycled products, the recycled products and raw materials for recycled products The quality of the material is improved. In addition, the passing wind speed v is set to 0.02 m / s or more and less than 0.15 m / s. If the reaction efficiency is 80% or more, for example, the absorption In the filter, the percentage of calcium carbonate is 80% or more. When rubber is used as a raw material for a recycled product, the recycled product and the raw material for the recycled product Quality improves.
