Description

  The present invention relates to a deodorizing cartridge that removes odors contained in air.

The cell space of the honeycomb deodorizing base material is filled with a deodorizing material made of a material different from that of the honeycomb deodorizing base material. There is a honeycomb deodorizing material composed of one or a combination of two or more selected from materials (see Patent Document 1). The activated carbon honeycomb can be made by adding powdered activated carbon as a main raw material to which phenol resin, clay, etc. are added, extruded to 60 cells / inch ² and then steam-activated at 850 ° C. This honeycomb deodorizing material constitutes a honeycomb deodorizing material by filling the cell space of the honeycomb deodorizing substrate with a deodorizing material made of a material different from the honeycomb deodorizing substrate, and each constituent material of the honeycomb deodorizing substrate and deodorizing material Is made from one or a combination of two or more selected from inorganic deodorants, organic deodorizers, and activated carbon materials, which improves the contact efficiency between air and the honeycomb deodorizer and deodorizer, and improves deodorization performance. In addition, it can be optimally used for deodorizing a space where malodors are generated. Furthermore, since the deodorizing performance can be further improved by widely covering the deodorizing range with respect to various offensive odors, it is possible to improve the performance with respect to the composite odor and prevent the re-release of malodors.

Japanese Patent Laid-Open No. 7-204442

  In the honeycomb deodorizing material disclosed in Patent Document 1, a plurality of cylindrical portions having a honeycomb-shaped air flow path extending in one direction through which air can flow are formed, and air flows through the air flow path. The odor contained in the air is removed, but since the air flow paths extend in one direction in parallel with each other, the air cannot flow from one air flow path to the other air flow path. Pass through these air flow paths quickly, and it is not possible to lengthen the air flow time in the air flow paths. Therefore, when the contact time of air to the honeycomb deodorizing substrate cannot be increased, it is difficult to efficiently use the deodorizing function of the honeycomb deodorizing substrate, and the odor contained in the air cannot be reliably removed There is.

  An object of the present invention is to provide a deodorizing cartridge capable of extending the air flow time in an air flow path and reliably removing odor contained in air.

  The premise of the present invention to solve the above problems is that a plurality of cylindrical portions having a first air flow path having a predetermined length extending in a first direction through which air can flow are formed, and the first air flow path is The deodorizing cartridge is provided with an air inlet opening at one end and an air outlet opening at the other end, and removes odor contained in air flowing from the air inlet and flowing through the first air flow path.

  As a feature of the present invention based on the above premise, a plurality of second air flow paths having a predetermined length extending in the second direction in which air can flow crossing the first air flow paths are formed in the cylindrical portions, In these cylinder parts, a 1st air flow path and a 2nd air flow path are connected, and it is in the air which flowed in from the air inflow port flowing through these 1st air flow paths and these 2nd air flow paths.

  As an example of the present invention, the cylindrical portions of the deodorizing cartridge are made of activated carbon that adsorbs odor, and the cross-sectional shape of the first air channel has a honeycomb shape.

  As another example of the present invention, the number of second air flow paths is smaller than the number of first air flow paths, and the opening area of the second air flow paths is smaller than the opening area of the first air flow paths.

  As another example of the present invention, the open end of the second air flow path is closed and extends into the deodorizing cartridge.

  As another example of the present invention, a plurality of third air passages having a predetermined length extending in a third direction in which air can flow are formed in the cylindrical portions so as to cross the first and second air passages. In these cylinder portions, the first air flow path and the third air flow path are connected, and the air flowing in from the air inlet is the first air flow path, the second air flow path, and the third air flow path. And flow through.

  As another example of the present invention, in the cylindrical portions, the second air flow path and the third air flow path are connected, or the second air flow path and the third air flow path are not connected.

  As another example of the present invention, the number of third air flow paths is smaller than the number of first air flow paths, and the opening area of the third air flow path is smaller than the opening area of the first air flow path.

  As another example of the present invention, the open end of the third air flow path is closed and extends into the deodorizing cartridge.

  As another example of this invention, the length dimension of the 1st direction of the 1st air flow path of a cylinder part exists in the range of 3-30 cm.

As another example of the present invention, the area of one end face of the deodorizing cartridge located on the air inlet side of the first air flow path is in the range of 9 to 400 cm ² , and the air outlet side of the first air flow path is on the air outlet side. The area of the other end surface of the deodorizing cartridge located is in the range of 9 to 400 cm ² .

As another example of the present invention, the number of first air flow paths in the cylindrical portion per 1 cm ^{2 of} the deodorizing cartridge is in the range of 30-60.

  As another example of the present invention, in the deodorizing cartridge, the air outlets of some of the first air passages are closed, and the total number of air outlets is larger than the total number of air inlets. Few.

  According to the deodorizing cartridge according to the present invention, a plurality of second air passages having a predetermined length extending in the second direction in which air can flow through the first air passages are formed in the cylindrical portions, Since the first air flow path and the second air flow path are connected to each other in the cylindrical portion, and the air flowing in from the air inflow port flows through the first air flow path and the second air flow path, the first air flow The air flowing in from the air inlet of the passage flows not only through the first air flow path but also through the second air flow path, and flows from the second air flow path into the other first air flow path. 2 flows through the air flow path and flows into the other first air flow path. In the deodorizing cartridge, air flows through the first air flow path and the second air flow path, and the air becomes a vortex or turbulent flow at the intersection of the first air flow path and the second air flow path. Since air resistance increases and the flow rate of air flowing through the air flow path decreases, the air flow time in the air flow path can be made sufficiently long, and the air contact time with the cylinder part is sufficient. The odor contained in the air can be surely removed.

  In the deodorizing cartridge in which the cylindrical portions are made of activated carbon that adsorbs odor and the cross-sectional shape of the first air channel has a honeycomb shape, the odor contained in the air is removed by the activated carbon. The air flowing in from the air inlet of the air flows not only through the first air flow path but also through the second air flow path, flows from the second air flow path into the other first air flow path, 2 Since it flows through the air flow path and flows into the other first air flow path, the air flow time in the air flow path can be lengthened, and the air contact time with respect to the cylindrical portion made of activated carbon can be reduced. The length can be increased, and the odor contained in the air can be reliably removed.

  The deodorizing cartridge in which the number of second air flow paths is smaller than the number of first air flow paths and the opening area of the second air flow path is smaller than the opening area of the first air flow path is the number of second air flow paths. Is larger than the number of the first air flow paths, and the opening area of the second air flow paths is larger than the opening area of the first air flow paths, a large number of first airs adjacent by one second air flow path There are cases where the flow paths are connected to each other, and a large number of fine air flow paths cannot be stretched around the deodorizing cartridge, but the number of the second air flow paths is smaller than the number of the first air flow paths, and the second air Since the opening area of the flow path is smaller than the opening area of the first air flow path, the adjacent first air flow paths are not connected by the second air flow path, and a large number of fine air flow paths are connected to the deodorizing cartridge. Can be stretched around. In the deodorizing cartridge, air flows through the first air flow path and the second air flow path, and the air becomes a vortex or turbulent flow at the intersection of the first air flow path and the second air flow path. Since air resistance increases and the flow rate of air flowing through the air flow path decreases, the air flow time in the air flow path can be lengthened, and the air contact time with the cylinder part can be lengthened. And the odor contained in the air can be surely removed.

  The deodorizing cartridge in which the open end of the second air flow path is closed has the second air flow while the air flowing in from the air inlet of the first air flow path flows through the first and second air flow paths. The air does not flow out of the cartridge from the open end of the passage, and air can flow from the air inlet to the air outlet of the first air flow path. Since the deodorizing cartridge flows out from the air outlet of the first air flow path after the air flows through the first air flow path and the second air flow path, the air passage time in the air flow path is increased. In addition, the contact time of the air with respect to the tube portion can be increased, and the odor contained in the air can be reliably removed.

  A plurality of third air flow paths having a predetermined length extending in a third direction through which air can flow crossing the first and second air flow paths are formed in the cylindrical portions, and the first air flow is formed in the cylindrical portions. The deodorizing cartridge in which the passage and the third air flow path are connected, and the air flowing in from the air inlet flows through the first air flow path, the second air flow path, and the third air flow path is the first deodorizing cartridge. The air flowing in from the air inlet of the air flow channel flows not only through the first air flow channel and the second air flow channel but also through the third air flow channel, and the other first air from the third air flow channel. It flows into the flow path and the second air flow path, further flows through the third air flow path, and flows into the other first air flow path and the second air flow path. In the deodorizing cartridge, air flows through the first to third air flow paths, and air becomes a vortex or turbulent flow at the intersection of the first to third air flow paths. Since the flow speed of the air flowing through the passage is reduced, the air flow time in the air flow path can be sufficiently increased, and the contact time of the air with respect to the cylindrical portion can be sufficiently increased. The odor contained in can be reliably removed.

  The deodorizing cartridge in which the second air flow path and the third air flow path are connected in these cylindrical portions or the second air flow path and the third air flow path are not connected is the second air flow in the cylindrical portions. When the flow path and the third air flow path are connected, the first to third air flow paths intersect, and the air flowing in from the air inlet of the first air flow path is not only the first air flow path. In addition, the second air flow path and the third air flow path are flown, the second and third air flow paths are flown into the other first air flow path, and the second and third air flow paths are further flowed. Since the air flows into the other first air flow path, the air flows through the first to third air flow paths, and the air flow time in the air flow path can be made sufficiently long, and with respect to the cylindrical portion. Air contact time can be made long enough to ensure the removal of odors in the air. It can be. When the second air flow path and the third air flow path are not connected in the cylindrical portions, the air flowing in from the air inlet of the first air flow path is transferred from the second air flow path to the other first air flow path. , Further flows through the second air flow path and flows into the other first air flow path, flows from the third air flow path into the other first air flow path, and further passes through the third air flow path. Since the air flows and flows into the other first air flow path, the air flows through the first to third air flow paths, and the air flow time in the air flow path can be made sufficiently long. The contact time of the air with respect to the part can be made sufficiently long, and the odor contained in the air can be reliably removed.

  The deodorizing cartridge in which the number of the third air flow paths is smaller than the number of the first air flow paths and the opening area of the third air flow path is smaller than the opening area of the first air flow path is the number of the third air flow paths. Is larger than the number of the first air flow paths, and the opening area of the third air flow path is larger than the opening area of the first air flow path, a large number of the first air adjacent by one third air flow path There are cases where the flow paths are connected to each other, and a large number of fine air flow paths cannot be stretched around the deodorizing cartridge, but the number of the third air flow paths is smaller than the number of the first air flow paths, and the third air Since the opening area of the flow path is smaller than the opening area of the first air flow path, the adjacent first air flow paths are not connected by the second air flow path, and a large number of fine air flow paths are connected to the deodorizing cartridge. Can be stretched around. In the deodorizing cartridge, air flows through the first to third air flow paths, and air becomes a vortex or turbulent flow at the intersection of the first to third air flow paths. Since the flow speed of the air flowing through the passage decreases, the air flow time in the air flow path can be lengthened, and the air contact time with the cylinder portion can be lengthened, and the odor contained in the air Can be reliably removed.

  The deodorizing cartridge in which the open end of the third air flow path is closed has the third air flow while the air flowing in from the air inlet of the first air flow path flows through the first to third air flow paths. The air does not flow out of the cartridge from the open end of the passage, and air can flow from the air inlet to the air outlet of the first air flow path. Since the deodorizing cartridge flows out from the air outlet of the first air flow path after the air flows through the first to third air flow paths, the air flow time in the air flow path can be extended. At the same time, it is possible to lengthen the contact time of the air with respect to the cylindrical portion, and it is possible to reliably remove the odor contained in the air.

  The deodorizing cartridge in which the length dimension in the first direction of the first air flow path of the cylinder part is in the range of 3 to 30 cm is the air in each air flow path by setting the length of the first air flow path to the above range. Can be sufficiently lengthened, and the contact time of the air with respect to the cylindrical portion can be sufficiently lengthened, and the odor contained in the air can be reliably removed.

The area of one end surface of the deodorizing cartridge located on the air inlet side of the first air passage is in the range of 9~400cm ^2, the area of the other end surface of the deodorizing cartridge located on the air flow outlet side of the first air channel Is in the range of 9 to 400 cm ^{2, since} the area of one end surface and the other end surface of the deodorizing cartridge is in the above range, a predetermined amount of air is passed through each air flow path and is contacted with the cylinder portion. And the odor contained in the air can be reliably removed.

Since the number of first air flow paths per 1 cm ² of the deodorizing cartridge is in the above range, the number of first air flow paths per 1 cm ² of the deodorizing cartridge is within the above range. A predetermined amount of air can be caused to flow through each air flow path and be brought into contact with the cylinder portion, so that odor contained in the air can be reliably removed.

  The deodorizing cartridge in which the air outlets of some of the first air passages among the first air passages are closed and the total number of air outlets is smaller than the total number of air inlets is the air flowing out from the air outlet. The amount of air is less than the amount of air flowing in from the air inlet, and the flow rate of air flowing through each air flow path is reduced accordingly, so the air flow time in each air flow path is lengthened. In addition, the contact time of the air with respect to the tube portion can be lengthened, and the odor contained in the air can be reliably removed.

  The details of the deodorizing cartridge according to the present invention will be described with reference to the accompanying drawings such as FIG. 1 which is a perspective view of the deodorizing cartridge 10A shown as an example. 2 is a diagram illustrating an example of the lower end surface 12 of the deodorizing cartridge 10A, and FIG. 3 is a partially enlarged view illustrating a part of the cylindrical portion 17 of the deodorizing cartridge 10A of FIG. FIG. 4 is a partially broken enlarged view similar to FIG. 3 showing an example of the air flow in the first and second air flow paths 18 and 19. 1 and 2, the vertical direction (first direction) is indicated by an arrow A (excluding FIG. 2), the front-rear direction (second direction) is indicated by an arrow B, and the horizontal direction (third direction) is indicated by an arrow C. 3 and 4, three cylindrical portions 17 are illustrated, but there are other cylindrical portions (not shown) adjacent to the cylindrical portions 17.

  The vertical direction is the first direction, the front-rear direction is the second direction, and the horizontal direction is the third direction. However, the first to third directions are not limited thereto, and the front-rear direction is the first direction. A horizontal direction that intersects one direction may be the second direction, and a vertical direction that intersects the first and second directions may be the third direction. The lateral direction may be the first direction, the longitudinal direction intersecting the first direction may be the second direction, and the front-rear direction intersecting the first and second directions may be the third direction.

  As shown in FIG. 1, the deodorizing cartridge 10 </ b> A is molded in a rectangular column shape that is long in the vertical direction. The three-dimensional shape of the cartridge 10A is not limited to a quadrangular prism shape, and the cartridge 10A may be molded into a regular quadrangular prism shape, or the cartridge 10A may be molded into a cylindrical shape that is long in the vertical direction. The cartridge 10A has an upper end surface 11 (one end surface), a lower end surface 12 (other end surface), and first to fourth side surfaces 13-16. The upper end surface 11 and the lower end surface 12 of the cartridge 10A are formed in a substantially rectangular shape. The first to fourth side surfaces 13 to 16 of the cartridge 10A are formed in a substantially rectangular shape that is long in the vertical direction. The cartridge 10A is formed with a plurality of cylindrical portions 17 having a regular hexagonal honeycomb shape and extending in the vertical direction. The cylindrical portions 17 of the cartridge 10A are made of activated carbon having a high odor adsorbing function (including a function of adsorbing radioactive substances such as iodine and cesium).

  The cylindrical portions 17 are adjacent to each other in the front-rear direction and the horizontal direction, and extend in the vertical direction in parallel with each other. The cylindrical portion 17 has a first air flow path 18 having a predetermined length through which air can flow. In addition to the first air flow path 18, a plurality of second air flow paths 19 having a predetermined length through which air can flow are formed in the cylindrical portions 17. As shown in FIGS. 1 and 2, the first air flow path 18 has a honeycomb shape with a regular hexagonal cross section, and extends in the longitudinal direction (first direction) in parallel with each other. The first air flow path 18 has an air inlet 20 that opens at one end (the upper end surface 11 of the cartridge 10A) and an air outlet 21 that opens at the other end (the lower end surface 12 of the cartridge 10A). It penetrates between the upper and lower end surfaces 11 and 12 of 10A.

  On the lower end surface 12 of the deodorizing cartridge 10 </ b> A, as shown in FIG. 2, the air outlets 21 of all the first air flow paths 18 are not opened, and some of the air in the first air flow paths 18 is opened. The air outlet 21 of the flow path 18 is closed (the frame-shaped portion of the lower end surface 12 in FIG. 2), and the air outlets 21 of some of the air flow paths 18 are opened (the center of the lower end face 12 in FIG. 2). Square part). Therefore, the total number of air outlets 21 is smaller than the total number of air inlets 20. The total number of air outlets 21 is adjusted to a range of ½ to 1/5 of the total number of air inlets 20. The total number of the air outlets 21 and the total number of the air inlets 20 may be the same without closing the air outlets 21 of some of the air channels 18 in the first air channel 17. .

  The second air flow path 19 is spaced in parallel in the vertical direction and the horizontal direction, and extends in the front-rear direction (second direction) intersecting the first air flow path 18. The second air flow path 19 has a circular cross-sectional shape. The second air channel 19 has an open end (air outlet) that opens to the first side surface 13 of the cartridge 10A closed, and an open end (air outlet) that opens to the third side surface 15 of the cartridge 10A closes. Yes. The second air flow path 18 is closed at the open ends of the first and third side surfaces 13 and 15 of the cartridge 10A, does not penetrate the first side surface 13 and the third side surface 15, and It extends only inside.

  The first air flow path 18 and the second air flow path 19 intersect each other inside the cartridge 10A so that they are substantially orthogonal to each other. The first air flow path 18 and the second air flow path 19 are the center line L2 of the first air flow path 18 and the center of the second air flow path 19 inside the cartridge 10A, as shown by a one-dot chain line in FIG. The line L3 intersects at the center of the air flow paths 18, 19.

  The number of the second air flow paths 19 is smaller than the number of the first air flow paths 18, and the opening area is smaller than the opening area of the first air flow path 18. When the number of the second air flow paths 19 is larger than the number of the first air flow paths 18 and the opening area of the second air flow paths 19 is larger than the opening area of the first air flow paths 18, one second There are cases where a large number of adjacent first air flow paths 18 are connected to each other by the air flow path 19, and a large number of fine air flow paths 18, 19 cannot be stretched around the cartridge 10 </ b> A. Is smaller than that of the first air flow path 18 and the opening area of the second air flow path 19 is smaller than that of the first air flow path 18. The air flow paths 18 are not connected to each other, and a large number of fine air flow paths 18, 19 can be stretched around the cartridge 10A.

  The longitudinal length L1 of the first air flow path 18 is in the range of 3 to 30 cm, preferably in the range of 5 to 15 cm. When the length dimension L1 of the first air flow path 18 is less than 3 cm, the air flow time in the air flow path 18 cannot be increased, and the contact time of air with the cylinder portion 17 (activated carbon) may be increased. Can not. In the cartridge 10A, the longitudinal length L1 of the first air flow path 18 is in the above range, the air flow time in the air flow paths 18 and 19 can be increased, and the cartridge portion 17 (activated carbon) Since the contact time of air can be lengthened, the odor contained in the air can be sufficiently adsorbed by the cylindrical portion 17, and the odor contained in the air can be reliably removed.

The number of first air flow paths 18 per 1 cm ² on the upper and lower end surfaces 11 and 12 of the deodorizing cartridge 10A is in the range of 30 to 50, preferably in the range of 35 to 45. If the number of the first air flow paths 18 per 1 cm ² of the upper and lower end surfaces 11 and 12 is less than 30, the number of the air flow paths 18 is small, and a predetermined amount of air cannot be brought into contact with the cylindrical portion 17 (activated carbon). The odor removal efficiency of the cartridge 10A is reduced. If the number of first air flow paths per 1 cm ² of the upper and lower end surfaces 11 and 12 exceeds 50, it is difficult to maintain the strength of the cartridge 10A, and the cartridge 10A may be damaged by impact. Since the number of the first air flow paths 18 per 1 cm ² on the upper and lower end surfaces 11 and 12 of the cartridge 10A is in the above range, a predetermined amount of air can be brought into contact with the cylindrical portion 17 (activated carbon), The contained odor can be sufficiently adsorbed to the cylindrical portion 17, and the odor contained in the air can be reliably removed. Further, since the cartridge 10A can maintain its strength, it can withstand a slight impact, and the cartridge 10A can be prevented from being inadvertently damaged.

Area of the upper surface 11 (one end surface) of the cartridge 10A which is located an air inlet 20 side of the first air flow path 18, the range of 9～400Cm ^2, preferably in the range of 16～100Cm ^2, first area of the lower end surface 12 (the other end face) of the cartridge 10A which is located an air outlet 21 side of the air flow path 18, the range of 9～400Cm ^2, preferably in the range of 16~100cm ^2. If the area of the upper end surface 11 or the lower end surface 12 is less than 9 cm ² , the number of the first air flow paths 18 in the cartridge 10A is reduced, and the odor removal efficiency of the cartridge 10A is reduced. The area of the upper end surface 11 and the lower end surface 12 of the cartridge 10A is in the above range, and a predetermined amount of air is passed through a sufficient number of the first air flow paths 18 to come into contact with the cylindrical portion 17 (activated carbon). Therefore, the odor contained in the predetermined amount of air can be sufficiently adsorbed by the cylindrical portion 17, and the odor contained in the air can be reliably removed.

  An example of the procedure for making the deodorizing cartridge 10A of FIG. 1 is as follows. First, the cartridge 10A (activated carbon honeycomb) in which the cylindrical portion 17 having the honeycomb-shaped first air flow path 18 is formed is manufactured. The cartridge 10A having the cylindrical portion 17 can be made by an existing extrusion molding using activated carbon powder or activated carbon fiber as a main raw material. Wood activated carbon, coconut activated carbon, and coal activated carbon can be used as the activated carbon. After making the cartridge 10A in which the cylindrical portion 17 (first air flow path 18) is formed, the first side 13 of the cartridge 10A toward the third side 15 (or from the third side 15) using a drill is used. A second air flow path 19 that extends straight (toward the first side face 13) is perforated. The second air flow paths 19 are formed in a row at predetermined equal intervals in the vertical direction and the horizontal direction, but may be formed at random in predetermined intervals in the vertical direction and the horizontal direction.

  After perforating the second air flow path 19, the open end (perforated hole) of the air flow path 19 that opens to the first side face 13 and the open end (perforated hole) of the air flow path 19 that opens to the third side face 15. Occlude. These open ends are blocked when a molten synthetic resin (which may include activated carbon powder) is applied to the first side surface 13 and the third side surface 15 and the side surfaces 13 and 15 are covered with a cured synthetic resin, or When the adhesive tape is applied to the first side surface 13 and the third side surface 15 and the side surfaces 13 and 15 are covered with the adhesive tape, or the side surfaces 13 and 15 are made of a pre-molded cylindrical plastic outer frame material. There are cases where it is coated.

  In order to close the air outlets 21 of some of the first air flow paths 18, a molten synthetic resin is applied to a part of the lower end surface 12 of the cartridge 10 </ b> A and cured. When covering the lower end surface 12 and closing the air outlets 21 of some of the first air passages 18, or attaching an adhesive tape to a part of the lower end surface 12 of the cartridge 10 </ b> A, and using the adhesive tape to lower the lower end surface 12 may be covered and the air outlets 21 of some of the first air flow paths 18 may be closed.

  In the deodorizing cartridge 10 </ b> A, as shown in FIG. 3, the first air flow path 18 and the second air flow path 19 are connected in the cylindrical portion 17, and the adjacent first air flow paths 18 are connected to the second air flow path 19. It is connected via. The air flowing in from the air inlet 20 flows through the first air flow path 18 and flows from the air flow path 18 into the second air flow path 19 as shown by an arrow L4 in FIG. After flowing through the flow path 19 and flowing again into the other first air flow path 18 from the second air flow path 19, the air flow path 18 is flowed through.

  The air flowing through the first and second air flow paths 18 and 19 is turbulent at the intersection of the first air flow path 18 and the second air flow path 19 and becomes vortex or turbulence. The flow becomes air resistance and the flow is slowed down, and the flow rate of air in the cartridge 10A is reduced. Further, the air outlets 21 of some of the first air passages 18 are closed at the lower end surface 12 of the cartridge 10 </ b> A, and the total area of the air outlets 21 of these first air passages 18 ( The total number) is smaller (less) than the total area (total number) of the air inlets 20, and the amount of air that can flow out of the air outlet 21 is smaller than the amount of air that can flow in from the air inlet 20. The flow of air flowing through the flow paths 18 and 19 is slowed down, and the flow rate of air in the cartridge 10A is reduced.

  While the flow velocity of the air decreases from the air inlet 20 toward the air outlet 21, the air gradually approaches the air outlet 21 through the air flow paths 18 and 19 and flows out from the air outlet 21 to the outside. . In the cartridge 10A, in the process in which the air flows through the first and second air flow paths 18 and 19, the cylinder portion 17 (activated carbon) comes into contact with the odor (including radioactive substances such as iodine and cesium) contained in the air. Adsorbed on activated carbon. The odor (including the radioactive substance adsorption function) contained in the air flowing out from the air outlet 21 through the first air passage 18 and the second air passage 19 is removed.

  In the deodorizing cartridge 10 </ b> A, a plurality of second air passages 19 having a predetermined length extending in the front-rear direction (second direction) through which air can flow through the first air passages 18 are formed in the cylindrical portions 17. In the cylindrical portion 17, the first air flow path 18 and the second air flow path 19 are connected, and the air flowing in from the air inlet 20 passes through the first air flow path 18 and the second air flow path 19. Therefore, the air flowing in from the air inlet 20 of the first air flow path 18 flows not only through the first air flow path 18 but also through the second air flow path 19 and from the second air flow path 19. It flows into the other first air flow path 18, further flows through the second air flow path 19, and flows into the other first air flow path 18.

  The deodorizing cartridge 10 </ b> A is configured such that air flows through the first air flow path 18 and the second air flow path 19, and the air is swirled or turbulent at the intersection of the first air flow path 18 and the second air flow path 19. Since the air resistance is increased by that amount, the air flow time in the air flow paths 18 and 19 can be made sufficiently long, and the amount of air flowing out from the air outlet 21 can be reduced. Since the flow rate of air flowing through the air flow paths 18 and 19 is reduced by that amount, the air flow time in the air flow paths 18 and 19 can be extended. The cartridge 10A can sufficiently lengthen the contact time of air with the cylindrical portion 17 (activated carbon), and can reliably remove odors (including radioactive substances) contained in the air.

The cylindrical portion 17 has a first air flow path 18 having a predetermined length through which air can flow. In addition to the first air flow path 18, a plurality of second air flow paths 18 and third air flow paths 22 having a predetermined length through which air can flow are formed in the cylindrical portions 17. The first air flow path 18 has a honeycomb shape having a regular hexagonal cross section, and extends in the longitudinal direction (first direction) in parallel with each other. The first air flow path 18 has an air inlet 20 that opens at one end (the upper end surface 11 of the cartridge 10B) and an air outlet 21 that opens at the other end (the lower end surface 12 of the cartridge 10B). It penetrates between the upper and lower end surfaces 11 and 12 of 10B.

  At the lower end surface 12 of the deodorizing cartridge 10B, the air outlets 21 of some of the first air passages 18 of the first air passages 18 are closed, similar to that of FIG. The air outlet 21 is opened (in FIG. 2). Therefore, the total number of air outlets 21 is smaller than the total number of air inlets 20. The total number of air outlets 21 is adjusted to a range of ½ to 1/5 of the total number of air inlets 20.

The number of the second air flow paths 19 is smaller than the number of the first air flow paths 18, and the opening area is smaller than the opening area of the first air flow path 18.

  The third air flow path 22 is spaced in parallel in the vertical direction and the front-rear direction, and extends in the lateral direction (third direction) intersecting with the first and second air flow paths 18 and 19. The third air channel 22 has a circular cross-sectional shape. The third air flow path 22 is closed at the open end (air outlet) that opens to the second side surface 14 of the cartridge 10B, and is closed at the open end (air outlet) that opens to the fourth side surface 16 of the cartridge 10B. Yes. The third air flow path 22 is closed at the open ends of the second side surface 14 and the fourth side surface 16 of the cartridge 10B, does not penetrate the second side surface 14 and the fourth side surface 16, and the cartridge 10B It extends only inside. The number of the third air flow paths 22 is smaller than the number of the first air flow paths 18, and the opening area is smaller than the opening area of the first air flow path 18. Further, the number of the third air flow paths 22 is substantially the same as the number of the second air flow paths 19, and the opening area is substantially the same as the opening area of the second air flow path 19.

  The first to third air flow paths 18, 19, and 22 intersect with each other so that they are substantially orthogonal to each other. The first to third air flow paths 18, 19, and 22 are center lines L2 of the first air flow path 18 and center lines of the second air flow path 19 inside the cartridge 10B, as shown by a one-dot chain line in FIG. L3 and the center line L5 of the third air flow path 22 intersect at the centers of the air flow paths 18, 19, and 22. Therefore, in the first to third air flow paths 18, 19, and 22, the first air flow path 18 and the second air flow path 19 intersect so as to be substantially orthogonal, and the second air flow path 19 and the third air flow path 19 The air flow path 22 intersects so as to be substantially orthogonal, and the third air flow path 22 and the first air flow path 18 intersect so as to be substantially orthogonal.

The air flow paths 18 are not connected to each other, and a large number of fine air flow paths 18, 19 can be stretched around the cartridge 10B.

The longitudinal length L1 of the first air flow path 18 in the deodorizing cartridge 10B, the number of the first air flow paths 18 per 1 cm ² on the upper and lower end surfaces 11 and 12 of the cartridge 10B, the air flow in the first air flow path 18 The area of the upper end surface 11 (one end portion) of the cartridge 10B located on the inlet 20 side and the area of the lower end surface 12 (other end surface) of the cartridge 10B located on the air outlet 21 side of the first air flow path 18 are shown in FIG. These are the same as those of the cartridge 10A.

In the deodorizing cartridge 10B, the longitudinal dimension L1 of the first air flow path 18 is in the above range, and the number of the first air flow paths 18 per 1 cm ² on the upper and lower end surfaces 11 and 12 of the cartridge 10B is in the above range. In addition, the area of the upper end surface 11 and the lower end surface 12 of the cartridge 10B is in the above range, and a predetermined amount of air is passed through a sufficient number of the first air flow paths 18 and the second and third air flow paths 19, 22. Since it can be made to flow and contact the cylinder part 17 (activated carbon), the odor contained in the air can be sufficiently adsorbed to the cylinder part 17 (activated carbon) and the odor contained in the air can be reliably removed. be able to.

  An example of the procedure for making the deodorizing cartridge 10B of FIG. 5 is as follows. First, the cartridge 10B (activated carbon honeycomb) in which the cylindrical portion 17 having the honeycomb-shaped first air flow path 17 is formed is manufactured. The cartridge 10B having the cylindrical portion 17 can be made by existing extrusion molding using activated carbon powder or activated carbon fiber as a main raw material, similar to that of FIG. After making the cartridge 10B in which the cylindrical portion 17 (first air flow path 18) is formed, the first side surface 13 toward the third side surface 15 of the cartridge 10B is used (or from the third side surface 15) using a drill. The second air flow path 19 that extends straight (toward the first side surface 13) is pierced, and a drill is used to move from the second side surface 14 to the fourth side surface 16 of the cartridge 10B (or the fourth side surface 16). The third air flow path 22 extending straight (from the second side surface 14 toward the second side surface 14) is perforated.

  When the second air channel 19 and the third air channel 22 are drilled, the air channels 19 and 22 are drilled so as to be connected (crossed) to each other. The second air flow paths 18 are formed in a line at predetermined equal intervals in the vertical direction and the horizontal direction, but may be randomly formed at predetermined intervals in the vertical direction and the horizontal direction. The third air flow paths 22 are formed in a row at predetermined equal intervals in the vertical direction and the front-rear direction, but may be formed randomly at predetermined intervals in the vertical direction and the front-rear direction.

  After perforating the second air flow path 19 and the third air flow path 22, the opening end (perforated hole) of the air flow path 19 that opens to the first side face 13 and the air flow path 19 that opens to the third side face 15 While closing the opening end (perforated hole), the opening end (perforated hole) of the third air flow path 22 that opens to the second side face 14 and the opening end of the third air flow path 22 that opens to the fourth side face 16 The (perforated hole) is closed. These open ends are blocked by applying a melted synthetic resin (which may include activated carbon powder) to the first to fourth side surfaces 13 to 16, and covering the first to fourth side surfaces 13 to 16 with the cured synthetic resin. If the adhesive tape is applied to the first to fourth side surfaces 13 to 16 and the first to fourth side surfaces 13 to 16 are covered with the adhesive tape, or a pre-molded cylindrical plastic outer frame In some cases, the first to fourth side surfaces 13 to 16 are covered with a material. The procedure for closing the air outlets 21 of some of the first air channels 18 is the same as that of the deodorizing cartridge 10A of FIG.

  In the deodorizing cartridge 10 </ b> B, as shown in FIG. 6, the first air flow path 18 and the second air flow path 19 are connected in the cylindrical portion 17, and the second air flow path 19 and the third air flow path 22 are connected. At the same time, the third air flow path 22 and the first air flow path 18 are connected, and the adjacent first air flow paths 18 are connected to each other via the second and third air flow paths 19 and 22.

  The air flowing in from the air inlet 20 flows through the first air flow path 18 as indicated by an arrow L4 in FIG. 7, and the second air flow path 19 and the third air flow from the air flow path 18 to the air flow. After flowing into the flow path 22 and flowing through the air flow paths 19, 22 and from the second air flow path 19 or the third air flow path 22 into the other first air flow path 18 again, Circulate.

  The air flowing through the first to third air flow paths 18, 19, 22 is turbulent at the intersections of the first to third air flow paths 18, 19, 22, resulting in vortex flow or turbulence. The turbulent flow becomes air resistance, the flow of which becomes dull, and the flow rate of air in the cartridge 10B decreases. Further, the air outlets 21 of some of the first air passages 18 are closed at the lower end surface 12 of the cartridge 10B, and the total area of the air outlets 21 of these first air passages 18 ( The total number) is smaller (less) than the total area (total number) of the air inlets 20, and the amount of air that can flow out of the air outlet 21 is smaller than the amount of air that can flow in from the air inlet 20. The flow of air flowing through the flow paths 18, 19, and 22 slows down, and the flow rate of air in the cartridge 10B decreases.

  While the flow velocity of the air decreases from the air inlet 20 toward the air outlet 21, the air gradually approaches the air outlet 21 through the air flow paths 18, 19, 22, and the air flows from the air outlet 21 to the outside. leak. In the cartridge 10B, in the process in which air flows through the first to third air flow paths 18, 19, and 22, the cylinder portion 17 (activated carbon) is contacted, and odors (including radioactive substances) contained in the air are adsorbed on the activated carbon. Is done. The odor (including radioactive material) contained in the air flowing out from the air outlet 21 through the first to third air flow paths 18, 19, 22 is removed.

  In the deodorizing cartridge 10 </ b> B, a plurality of second air passages 19 having a predetermined length extending in the front-rear direction (second direction) through which air can flow through the first air passages 18 are formed in the cylindrical portions 17. In addition, a plurality of third air passages 22 having a predetermined length extending in the lateral direction (third direction) through which air can flow crossing the first and second air passages 18 and 19 are formed in the cylindrical portions. 17, the first air flow path 18, the second air flow path 19, and the third air flow path 22 are connected to each other in the cylindrical portion 17, and the air flowing in from the air inlet 20 is the first to third air. Since the flow paths 18, 19, and 22 flow, the air that flows in from the air inlet 20 of the first air flow path 18 not only the first air flow path 18 but also the second air flow path 19 and the third air. While flowing through the flow path 22, the second air flow path 19 and the third air flow path 22 are connected to the other side. It flows into the first air channel 18, further flows through the second air passage 19 and the third air passage 22 flows into the first air channel 18 of the other.

  In the deodorizing cartridge 10B, air flows through the first to third air flow paths 18, 19, and 22 and air becomes vortex or turbulent at the intersection of the first to third air flow paths 18, 19, and 22. Since the air resistance increases accordingly, the air flow time in the air flow paths 18, 19, and 22 can be made sufficiently long, and the amount of air flowing out from the air outlet 21 is the air inlet 20. The amount of air flowing in from the air flow path is smaller, and the speed of the air flowing through the air flow paths 18, 19, and 22 is reduced accordingly, so that the air flow time in the air flow paths 18, 19, and 22 is lengthened. Can do. The cartridge 10B can sufficiently increase the contact time of air with the cylindrical portion 17 (activated carbon), and can reliably remove odors (including radioactive substances) contained in the air.

In FIG. 8, the vertical direction (first direction) is indicated by an arrow A, the front-rear direction (second direction) is indicated by an arrow B, and the horizontal direction (third direction) is indicated by an arrow C. In FIGS. 9 and 10, three cylindrical portions 17 are illustrated, but there are other cylindrical portions adjacent to the cylindrical portions 17.

  The deodorizing cartridge 10C is different from that of FIG. 5 in that the second air flow path 19 and the third air flow path 22 are not directly connected but connected via the first air flow path 18. Since the other configuration is the same as that of the cartridge 10B in FIG. 5, the same reference numerals as those in FIG. 5 are given, and the detailed description of the other configurations in the cartridge 10C is omitted by using the description of FIG.

And the 3rd air flow path 22 is formed. At the lower end surface 12 of the cartridge 10 </ b> C, as in FIG. 1, the air outlets 21 of some of the air flow paths 18 of the first air flow paths 18 are closed, and the air of some of the air flow paths 18 is closed. The outflow port 21 is open | released (FIG. 2 assistance). The total number of the air outlets 21 is smaller than the total number of the air inlets 20 and is adjusted to a range of ½ to 1/5 of the number of the air inlets 20.

  The second air flow path 19 is spaced in parallel in the vertical direction and the horizontal direction, and extends in the front-rear direction (second direction) intersecting the first air flow path 18. The second air flow path 19 has a circular cross-sectional shape. The second air flow path 19 is closed at the opening end (air outlet) that opens to the first side surface 13 and is closed at the opening end (air outlet) that opens to the third side surface 15, and only inside the cartridge 10 </ b> C. It extends. The number of the second air flow paths 19 is smaller than the number of the first air flow paths 18, and the opening area is smaller than the opening area of the first air flow path 18.

  The third air flow path 22 is spaced in parallel in the vertical direction and the front-rear direction, and extends in the lateral direction (third direction) intersecting with the first and second air flow paths 18 and 19. The third air channel 22 has a circular cross-sectional shape. The third air flow path 22 is closed at the open end (air outlet) that opens to the second side surface 14, and is closed at the open end (air outlet) that opens to the fourth side surface 16, and only inside the cartridge 10C. It extends. The number of the third air flow paths 22 is smaller than the number of the first air flow paths 18, and the opening area is smaller than the opening area of the first air flow path 18. Further, the number of the third air flow paths 22 is substantially the same as the number of the second air flow paths 19, and the opening area is substantially the same as the opening area of the second air flow path 19.

  The first air flow path 18 and the second air flow path 19 are such that the air flow paths 18 and 19 intersect each other so that they are substantially orthogonal to each other. The first air flow path 18 and the second air flow path 19 are the center line L2 of the first air flow path 18 and the center of the second air flow path 19 inside the cartridge 10C, as shown by the one-dot chain line in FIG. The line L3 intersects at the center of the air flow paths 18, 19. The first air flow path 18 and the third air flow path 22 intersect with each other so that they are substantially orthogonal to each other. The first air flow path 18 and the third air flow path 22 are the center line L2 of the first air flow path 18 and the center of the third air flow path 22 inside the cartridge 10C, as shown by a one-dot chain line in FIG. The line L5 intersects at the center of the air flow paths 18, 22. The second air flow path 19 and the third air flow path 22 are not directly connected to each other but are connected via the first air flow path 18.

  In the deodorizing cartridge 10C, the number of the second air flow paths 19 is smaller than that of the first air flow paths 18, and the opening area of the second air flow paths 19 is smaller than that of the first air flow paths 18. The plurality of adjacent first air flow paths 18 are not connected by the second air flow path 19 of the book, and a large number of fine air flow paths 18, 19, and 22 can be stretched around the cartridge 10C. Further, since the number of the third air flow paths 22 is smaller than that of the first air flow paths 18 and the opening area of the third air flow paths 22 is smaller than that of the first air flow paths 18, The three air flow paths 22 do not connect a large number of adjacent first air flow paths 18, and a large number of fine air flow paths 18, 19, and 22 can be stretched around the cartridge 10C.

These are the same as those of the cartridge 10A.

In the deodorizing cartridge 10C, the longitudinal length L1 of the first air flow path 18 is in the above range, and the number of the first air flow paths 18 per 1 cm ² on the upper and lower end surfaces 11 and 12 of the cartridge 10C is in the above range. In addition, the area of the upper end surface 11 and the lower end surface 12 of the cartridge 10C is in the above range, and a predetermined amount of air is passed through a sufficient number of the first air flow paths 18 to be in contact with the cylindrical portion 17 (activated carbon). Therefore, the odor contained in the air can be sufficiently adsorbed by the cylindrical portion 17 (activated carbon), and the odor contained in the air can be reliably removed.

  An example of the procedure for making the deodorizing cartridge 10C of FIG. 8 is the same as the procedure for making the deodorizing cartridge 10C of FIG. 5, but when the second air channel 19 and the third air channel 22 are perforated, the air channels 19 , 22 are alternately perforated so that they do not connect (do not cross) each other. In the cartridge 10 </ b> C, as shown in FIG. 9, the first air flow path 18 and the second air flow path 19 are connected in the cylindrical portion 17, and the adjacent first air flow paths 18 connect the second air flow path 19. The first air flow path 18 and the third air flow path 22 are connected to each other, and the adjacent first air flow paths 18 are connected to each other via the third air flow path 22.

  The air flowing in from the air inlet 20 flows through the first air flow path 18 and flows into the second air flow path 19 from the first air flow path 18 as indicated by an arrow L4 in FIG. After flowing through the air flow path 19 and flowing again from the second air flow path 19 into the other first air flow path 18, the first air flow path 18 is flowed through. In addition, after flowing into the third air flow path 22 from the first air flow path 18, flowing through the air flow path 22, and flowing into the other first air flow path 18 again from the third air flow path 22, One air flow path 18 flows.

  The air flowing through the first and second air flow paths 18 and 19 is turbulent at the intersection of the first air flow path 18 and the second air flow path 19 and becomes vortex or turbulence. Becomes air resistance, the flow of which slows down, and the flow rate of air in the deodorizing cartridge 10C decreases. The air flowing through the first and third air flow paths 18 and 22 is turbulent at the intersection of the first air flow path 18 and the third air flow path 22 and becomes vortex or turbulence. Becomes air resistance and the flow is slowed down, and the flow rate of air in the cartridge 10C decreases. Further, the air outlets 21 of some of the first air passages 18 are closed at the lower end surface 12 of the cartridge 10 </ b> C, and the total area of the air outlets 21 of the first air passages 18 ( The total number) is smaller (less) than the total area (total number) of the air inlets 20, and the amount of air that can flow out of the air outlet 21 is smaller than the amount of air that can flow in from the air inlet 20. The flow of air flowing through the flow paths 18, 19, and 22 is slowed down, and the flow rate of air in the cartridge 10C is reduced.

  While the flow velocity of the air decreases from the air inlet 20 toward the air outlet 21, the air gradually approaches the air outlet 21 through the air flow paths 18, 19, 22, and the air flows from the air outlet 21 to the outside. leak. In the cartridge 10 </ b> C, in the process of air flowing through the first to third air flow paths 18, 19, 22, the cylinder portion 17 (activated carbon) is contacted, and odors (including radioactive substances) contained in the air are adsorbed on the activated carbon.

  The deodorizing cartridge 10 </ b> C is configured such that the air flows through the first to third air flow paths 18, 19, and 22, and the intersection of the first air flow path 18 and the second air flow path 19 or the first air flow path 18. Since the air becomes vortex or turbulent at the intersection of the third air flow path 22 and the air resistance increases accordingly, the air flow time in the air flow paths 18, 19, and 22 can be made sufficiently long. Furthermore, the amount of air flowing out from the air outlet 21 is smaller than the amount of air flowing in from the air inlet 20, and the speed of the air flowing through the air flow paths 18, 19, and 22 is correspondingly reduced. The air flow time in the air flow paths 18, 19, and 22 can be increased. The cartridge 10C can sufficiently increase the contact time of air with the cylinder portion 17 (activated carbon), and can reliably remove odors (including radioactive substances) contained in the air.

  FIG. 11 is a diagram illustrating an example of use of the deodorizing cartridges 10A, 10B, and 10C. These deodorizing cartridges 10A, 10B, and 10C are included in the air flowing into the rooms 24A to 24F, for example, by being installed in a building 23 (especially a nursing home or a hospital) where many rooms 24A to 24F are installed. It is used for removing odors (including radioactive substances) and odors (including radioactive substances) contained in air flowing out of the rooms 24A to 24F. These deodorizing cartridges 10A, 10B, and 10C are installed as they are in, for example, a refrigerator, a library, a cupboard, a closet, a shoe box, and a toilet where natural convection occurs, thereby removing odors contained in the air by a passive method. It can also be used.

  As an example, the deodorizing cartridges 10A, 10B, and 10C can be installed in the vicinity of the ventilation fan 25 in the room. When the cartridges 10A, 10B, and 10C are installed in the vicinity of the ventilation fan 25, the air inlet 20 is directed toward the air inflow side, and the air outlet 21 is directed toward the air outflow side. When the ventilation fan 25 is operated to exhaust the indoor air to the outside, the air flows by the ventilation fan 25 to cause the air to flow into the first to third air flow paths 18, 19, 22 (cartridge 10A) of the cartridges 10A, 10B, 10C. In this case, the first and second air flow paths 18 and 19) are passed through, the odor contained in the air is removed, and the clean air is released to the outside.

  When the deodorizing cartridges 10A, 10B, and 10C are installed in the vicinity of the ventilation fan 25 of each private room in the nursing home, the air from which the aging odor (including other odors) that fills the room of each private room is removed is released to the outside. In this way, it is possible to prevent the aging odor from flowing into other private rooms. In addition, when the cartridges 10A, 10B, and 10C are installed in the vicinity of a ventilating fan in each hospital room, the air from which chemical odors (including other odors) filling the rooms in each hospital room are removed is released to the outside. This prevents chemical odors from flowing into other hospital rooms.

  As another example, the deodorizing cartridges 10A, 10B, and 10C can be installed in the vicinity of the windows 26 of the rooms 24A to 24F. When the cartridges 10A, 10B, and 10C are installed in the vicinity of the window 26, the air inlet 20 is directed to the air inflow side, and the air outlet 21 is directed to the air outflow side. When the ventilation fan 25 is operated to exhaust indoor air to the outside or when the window 26 is opened for ventilation, air flows into the room from the open space of the window 26. At this time, air flows through the first to third air flow paths 18, 19, and 22 (first and second air flow paths 18 and 19 in the case of the cartridge 10A) of the cartridges 10A, 10B, and 10C and is included in the air. The odor is removed and clean air flows into the room.

  When the deodorizing cartridges 10A, 10B, and 10C are installed in the vicinity of the windows 26 of the individual rooms of the nursing home, the air from which the odors (including other odors and radioactive substances) contained in the outdoor air are removed is removed from the indoors of the individual rooms. By letting it flow into the odor, the odor can be prevented from flowing into the individual rooms. In addition, when the cartridges 10A, 10B, and 10C are installed in the vicinity of the window 26 of each hospital room, the air from which the odor (including other odors and radioactive substances) contained in the outdoor air has been removed is removed from each room. By letting it flow into, it is possible to prevent chemical odor from flowing into other hospital rooms. Odor can be prevented from entering each room.

  As another example, the deodorizing cartridges 10A, 10B, and 10C can be installed in the vicinity of the doors 27 of the rooms 24A to 24F. When the cartridges 10A, 10B, and 10C are installed in the vicinity of the door 27, the air inlet 20 is directed to the air inflow side, and the air outlet 21 is directed to the air outflow side. When the door 27 is opened and closed, air flows into the room through the open space of the door 27 or flows out of the room. At this time, air flows through the first to third air flow paths 18, 19, and 22 (first and second air flow paths 18 and 19 in the case of the cartridge 10A) of the cartridges 10A, 10B, and 10C and is included in the air. The odor is removed and clean air flows into the room or clean air flows out of the room.

  When the deodorizing cartridges 10A, 10B, and 10C are installed in the vicinity of the doors 27 of the individual rooms of the nursing home, the air from which the odors (including other odors) contained in the outdoor air are removed flows into the rooms of the individual rooms. In this way, it is possible to prevent the odor from flowing into each individual room, and by releasing the air from which the aging odor (including other odors) filling each room is removed to the outside, Inflow of aging odor can be prevented. In addition, when the cartridges 10A, 10B, and 10C are installed in the vicinity of the door 27 of each hospital room, air from which chemical odors (including other odors) contained in the outdoor air are removed flows into the rooms of each hospital room. By doing so, inflow of chemical odor to other hospital rooms can be prevented. The inflow of chemical odors into other hospital rooms can be prevented by releasing the air from which the chemical odors (including other odors) filling each room are removed, and the odor can be prevented from flowing into each room. Can be prevented.

FIG. 14 is a top view of the deodorizing device 30 shown in a state where the deodorizing cartridges 10A, 10B, and 10C are accommodated. These deodorizing cartridges 10 </ b> A, 10 </ b> B, and 10 </ b> C can be used as a deodorizing material for the deodorizing device 30. By installing the deodorizing device 30 containing the deodorizing cartridges 10A, 10B, and 10C at a predetermined location, the odor contained in the air at that location is removed.

  The deodorizing device 30 is formed of a case 31 and a pedestal 32, and a blower fan 33 (propeller fan with a DC motor). Any of the deodorizing cartridges 10A, 10B, and 10C can be used as the deodorizing device 30. The deodorizing device 30 is a desktop type used by being placed on a table, desk, floor, hallway, toilet or the like. The case 31 is made of a transparent synthetic resin and molded into a cylindrical shape. The case 31 includes a peripheral wall 35 having a circular cross section extending in the vertical direction and a circular top opening 37 surrounded by an upper end edge 36 of the peripheral wall 35. Note that the shape of the case 31 is not limited to a cylindrical shape, and the case 31 may be formed in a rectangular tube shape.

  The peripheral wall 35 has a predetermined thickness and is formed in a cylindrical shape that is long in the vertical direction. The peripheral wall 35 has a lower end portion 38 positioned on the pedestal 32 side, an upper end portion 40 positioned on the opposite side, and an intermediate portion 39 positioned between the upper and lower end portions 38, 40. A circular flange 41 projecting inward in the radial direction of the case 31 is formed in the vicinity of the boundary between the lower end portion 38 and the intermediate portion 39 of the peripheral wall 35. The flange 41 supports the upper end surface 11 (one end surface) of the deodorizing cartridges 10A, 10B, and 10C. A plurality of circular through holes 42 (air inflow holes) penetrating the peripheral wall 35 are formed in the lower end portion 38 of the peripheral wall 35 below the flange 41. The through holes 42 are arranged at substantially equal intervals in the direction around the peripheral wall 35.

  The pedestal 32 is made of a synthetic resin and molded into a cylindrical shape that spreads toward the end. The pedestal 32 has a top portion 43 and a bottom portion 45, and an intermediate portion 44 extending between the top bottom portions 43, 45. The top portion 43 of the pedestal 32 is connected to the case through connecting means (screwing with screws formed on the lower end portion 38 of the peripheral wall 35 and the top portion 43 of the pedestal 32, adhesion with an adhesive, screwing, etc.) (not shown). 31 is connected to the lower part (the lower end part 38 of the peripheral wall 35), and the bottom part 45 abuts on the upper surface of the place where the deodorizing device 30 is placed. On the outer peripheral surface of the intermediate portion 44 of the pedestal 32, a flexible flexible solar panel 46 extending in the circumferential direction is installed (fixed) via fixing means (adhesion with an adhesive, screwing, etc.) (not shown). ing.

  The flexible solar panel 46 converts light energy into electricity and sends the electricity to the blower fan 33. An ON / OFF switch 47 and a rotation speed variable dial 48 are attached to the outer peripheral surface of the intermediate portion 44 of the pedestal 32. When the ON / OFF switch 47 is turned ON, the blower fan 33 is activated, and when the ON / OFF switch 47 is turned OFF, the blower fan 33 is stopped.

  A rotation speed variable circuit (not shown) for changing the rotation speed of the blower fan 33 is installed inside the base 32. As an example of the rotation speed variable circuit, feedback is performed using an electromotive force (BackEMF) generated during rotation of the DC motor, and the rotation speed constant control is performed by changing the duty ratio of the PWM control. As other means for changing the rotational speed, there are cases where a variable resistor is installed in series, an auto transformer is installed, a chopper circuit using a thyristor is used, and the like.

  During operation of the blower fan 33, as indicated by arrows N1 and N2 in FIG. 12, the rotation speed variable circuit is operated by rotating the rotation speed variable dial 48 in either the clockwise direction or the counterclockwise direction. Then, the rotation speed of the fan 33 is changed. For example, rotating the dial 48 in the clockwise direction indicated by the arrow N1 increases the rotational speed of the fan 33, and rotating the dial 48 in the counterclockwise direction indicated by the arrow N2 decreases the rotational speed of the fan 33. . In addition, it replaces with the flexible solar panel 46 installed in the outer peripheral surface of the base 32, and the battery (not shown) which sends electricity to the ventilation fan 33 (DC motor) can also be utilized. The battery is detachably installed in a battery box (not shown) attached inside the pedestal 32.

  The blower fan 33 is formed by a DC motor 49 and a propeller 50 attached to the shaft of the motor 49. The DC motor 49 of the blower fan 33 is fitted into a motor fixing hole that opens in the center of the top 43 of the pedestal 32, and is fixed to the motor via fixing means (adhesion with an adhesive, screwing, etc.) (not shown). It is fixed to the hole. The DC motor 49 is connected to an ON / OFF switch 47, a rotation speed variable dial 48, and a flexible solar panel 46 (or a battery) via wiring (not shown). The propeller 50 of the blower fan 33 is disposed at the center of the lower end portion 38 of the peripheral wall 35.

  The procedure for using the deodorizing apparatus 30 will be described as follows. First, one of the deodorizing cartridges 10A, 10B, and 10C is stored inside the storage case 31. The cartridges 10A, 10B, and 10C are put into the case 31 through the top opening 37. The cartridges 10 </ b> A, 10 </ b> B, and 10 </ b> C are housed inside the case 31 with the upper end surface 11 facing downward and the lower end surface 12 facing upward. When the cartridges 10A, 10B, and 10C are inserted into the case 31, the cartridges 10A, 10B, and 10C are positioned immediately above the blower fan 33, and the upper end surfaces 12 of the cartridges 10A, 10B, and 10C abut against the flange 41, and the cartridges 10A, 10C, 10B and 10C are supported by the flange 41.

  The length of the storage case 31 in the vertical direction is larger than the length L1 of the cartridges 10A, 10B, and 10C, and the volume of the case 31 is large enough to accommodate the cartridges 10A, 10B, and 10C. The cartridges 10 </ b> A, 10 </ b> B, and 10 </ b> C are entirely accommodated in the case 31. The first air flow paths 18 of the cylindrical members 17 of the cartridges 10 </ b> A, 10 </ b> B, 10 </ b> C extend in the vertical direction between the lower end portion 38 and the upper end portion 40 of the case 31. The air inlet 20 of the first air passage 18 is located immediately above the fan 33 and faces the fan 33, and the air outlet 21 of the first air passage 18 is located on the top opening 37 side. After the cartridges 10A, 10B, and 10C are housed inside the case 31, the deodorizing device 30 is placed on a table, desk, floor, hallway, toilet, etc., and the ON / OFF switch 47 is turned on.

  When the switch 47 is turned on, electricity is sent from the solar panel 46 (or battery) to the DC motor 49, and the propeller 50 is rotated by the rotation of the shaft of the DC motor 49. When the propeller 50 rotates, as indicated by an arrow N3 in FIG. 1, an air flow is generated from the lower end portion 38 of the case 31 toward the upper end portion 40, and air flows into the inside of the case 31 from these through holes 42, The air flows into the air flow path 18 from the air inlet 20 of the first air flow path 16 of the cylindrical members 17.

  When the deodorizing cartridge 10 </ b> A is used, the air flowing in from the air inlet 20 flows through the first air flow path 18 and also flows from the air flow path 18 into the second air flow path 19 and passes through the air flow path 19. After flowing and flowing again from the second air passage 19 into the first air passage 18, the air passage 18 is passed through. In the process in which air flows through the first and second air flow paths 18 and 19, the cylinder portion 17 (activated carbon) comes into contact with the odor (including radioactive substances such as iodine and cesium) adsorbed on the activated carbon. The The cleaned air flows out of the cartridge 10 </ b> A from the air outlet 21 of the first air flow path 18. Clean air that has flowed out of the cartridge 10 </ b> A is sent to the outside of the case 31 from the top opening 37 of the case 31. After the cartridge 10A has been used for a predetermined period, the cartridge 10A is taken out from the case 31 and a new cartridge 10A is stored in the case 31.

  When the deodorizing cartridge 10B or the deodorizing cartridge 10C is used, the air flowing in from the air inlet 20 flows through the first air passage 18 and from the air passage 18 to the second air passage 19 or the third air flow. The air flows into the passage 22 and flows through the air flow paths 19 and 22, then flows again into the first air flow path 18 from the second air flow path 19 and the third air flow path 22, and then flows through the air flow path 18. . In the process in which air flows through the first to third air flow paths 18, 19, 22, the cylinder portion 17 (activated carbon) comes into contact, and odors (including radioactive substances) contained in the air are adsorbed by the activated carbon. The cleaned air flows out of the cartridges 10B and 10C from the air outlet 21 of the first air flow path 18. The clean air that has flowed out of the cartridges 10 </ b> B and 10 </ b> C is sent from the top opening 37 of the case 31 to the outside of the case 31. After the cartridges 10B and 10C have been used for a predetermined period, the cartridges 10B and 10C are taken out from the case 31 and new cartridges 10B and 10C are stored in the case 31.

In the deodorizing device 30, the rotation speed of the blower fan 33 (propeller 50) is in the range of 60 to 480 r / min, and the flow velocity of the air flowing through the first air flow path 18 of the cartridges 10A, 10B, and 10C is 0.01 to 0. It is adjusted to the range of 1 m ³ / sec. When the rotational speed of the fan 33 exceeds 480 r / min and the flow velocity of the air flowing through the first air flow path 18 exceeds 0.1 m ³ / sec, the air flow speed in the air flow path 18 is high, and the air is air Since it passes the flow paths 18, 19, and 22 in a short time, the contact time of the air with respect to the cylinder material 17 (activated carbon) becomes short, and the odor contained in the air cannot fully be adsorbed to the activated carbon. In the deodorizing device 30, the rotational speed of the blower fan 33 is in the above range, the flow velocity of the air flowing through the first air flow path 18 is in the above range, and the air slowly flows through the air flow paths 18, 19, 22. The contact time of air with respect to the tubular member 17 (activated carbon) can be extended, and the odor contained in the air can be sufficiently adsorbed by the activated carbon.

  The deodorizing device 30 is a first air flow path that extends in the vertical direction from the upper end surface 11 to the lower end surface 12 of the deodorizing cartridges 10 </ b> A, 10 </ b> B, 10 </ b> C through the air taken into the case 31 from the through hole 42 by the blower fan 33. The air can be reliably brought into contact with the cylindrical member 17 (activated carbon) by allowing the air to flow into the air flow paths 18, 19, and 22 of the cylindrical member 17 made of activated carbon. The contained odor can be sufficiently adsorbed on the activated carbon.

  The deodorization device 30 can reliably remove the odor contained in the air by the cylindrical portion 17 (activated carbon), can produce clean air, and can send clean air to the outside from the top opening 37 of the case 31. it can. In the deodorizing device 30, the cartridges 10 </ b> A, 10 </ b> B, and 10 </ b> C are positioned immediately above the blower fan 33, so that the air taken into the inside of the case 31 from the through holes 42 is supplied to the air flow paths 18, 19, and 22 Since it can be made to flow uniformly to all, the deodorizing function of cartridge 10A, 10B, 10C can be utilized to the maximum, and the deodorizing efficiency in the apparatus 30 can be improved.
