Description

  The present invention relates to a deodorizing apparatus for removing odorous components in exhaust gas generated from garbage and the like, and a garbage treatment apparatus using the same.

  2. Description of the Related Art Conventionally, as a deodorization apparatus used for a garbage disposal apparatus, an apparatus that decomposes odor components in exhaust gas by flowing exhaust gas into a spiral catalyst deodorization unit is known (for example, Patent Document 1). reference).

  FIG. 9 shows an example of the configuration, and a catalyst deodorizing unit 12 and an exhaust fan 13 are communicated with an exhaust passage 11 connected to a garbage disposal device. The catalyst deodorization unit 12 is formed by spirally winding a band-shaped metal thin plate around a metal pipe 14, a fin catalyst 15 carrying a platinum catalyst on the surface thereof, a catalyst heater 16 inserted into the pipe 14, and a fin A closed portion 17 that seals the open end of the catalyst 15 is built in a cylindrical deodorizing container 18 and is closed by a catalyst lid 19. The closing portion 17 is composed of a metal thin plate 20 and a ceramic vapor insulating material 21 from the inside. The deodorizing passage 22 is formed in a spiral shape by a gap between the fin catalyst 15 and the thin plate 20 and the pipe 14.

Operation | movement of the deodorizing apparatus comprised as mentioned above is demonstrated. The garbage is dried by the garbage treatment device, and the exhaust gas containing water vapor (for example, about 100 ° C.) flows into the catalyst deodorization section 12 through the exhaust passage 11 and flows through the deodorization passage 22. At that time, the catalyst of the fin catalyst 15 heated by the catalyst heater 16 through the pipe 14 and having a temperature rise decomposes odor components in the exhaust gas. The deodorized exhaust gas is exhausted from the exhaust fan 13 to the outside.
Japanese Patent No. 3334462

  However, in the above-described conventional configuration, when the strip-shaped metal thin flat plate is spirally wound around the pipe 14, wrinkles are generated in the strip-shaped thin metal flat plate due to the difference in inner and outer diameters, so that the workability is very poor. It had the problem that. On the other hand, the width (outer diameter) of the strip-shaped metal thin plate cannot be increased for suppressing wrinkles. As a result, in order to secure the amount of catalyst, a large number of strip-like thin metal flat plates must be spirally wound, which has the problem that the catalyst deodorizing section 12 becomes very large.

  In addition, if the seal between the open end of the fin catalyst 15 and the closed portion 17 is insufficient, the exhaust gas short-passes the catalyst deodorizing portion 12, so that the deodorizing performance is significantly lowered. In order to prevent this, a thin metal plate 20 is wound around the open end of the fin catalyst 15, and a heat insulating material 21 is also wound around, and it is pushed into the deodorizing container 18 while being twisted and sealed with the catalyst lid 19. That is, since the seal between the open end of the fin catalyst 15 and the closed portion 17 is secured by the elasticity of the heat insulating material 21, there is a problem that the assemblability is very poor.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a deodorizing apparatus and a garbage disposal apparatus using the deodorizing apparatus that are compact and improve workability and assemblability. .

  In order to solve the above-described conventional problems, the deodorization apparatus of the present invention is a deodorization device formed between a catalyst portion supporting a catalyst on a flat plate arranged in a zigzag manner and an adjacent flat plate of the catalyst portion and communicating with each other. A passage, a closed portion that closes the opening of the deodorizing passage, a heating means provided in the deodorizing passage, an introduction portion having a passage inlet communicating with the upstream deodorizing passage, and a passage communicating with the downstream deodorizing passage And a discharge portion having an outlet.

  As a result, the heating means directly heats the exhaust gas and raises the temperature rapidly, while heating the flat plate by radiation. Next, as the exhaust gas flows through the deodorizing passage, the flat plate is heated to raise the temperature, so the catalyst supported on the flat plate decomposes the odor component of the exhaust gas. On the other hand, since the catalyst is supported on a flat plate arranged so that the catalyst portion is zigzag, the stress on the flat plate is small, and the workability is improved. Further, since the deodorizing passage is formed between the flat plates adjacent to each other and communicated with each other, the deodorizing passage can be formed thin, the catalyst portion can be made compact and the assemblability can be improved.

  In addition, the garbage processing apparatus of the present invention can be made compact by using a deodorizing device that is compact and improves workability and assemblability, and is used in a household kitchen. It will be suitable for

  The first invention is such that a catalyst portion carrying a catalyst on a flat plate arranged in a zigzag manner, a deodorization passage formed between adjacent flat plates of the catalyst portion and communicating with each other, and an open portion of the deodorization passage are closed. The deodorizing apparatus includes a closed portion, a heating means provided in the deodorizing passage, an introduction portion having a passage inlet communicating with the upstream deodorizing passage, and a discharge portion having a passage outlet communicating with the downstream deodorizing passage. By doing so, the heating means directly heats the exhaust gas to rapidly increase the temperature, while heating the flat plate by radiation. Next, as the exhaust gas flows through the deodorizing passage, the flat plate is heated to raise the temperature, so the catalyst supported on the flat plate decomposes the odor component of the exhaust gas. On the other hand, since the catalyst is supported on a flat plate arranged so that the catalyst portion is zigzag, the stress on the flat plate is small, and the workability is improved. Further, since the deodorizing passage is formed between the flat plates adjacent to each other and communicated with each other, the deodorizing passage can be formed thin, the catalyst portion can be made compact and the assemblability can be improved.

  In the second invention, in particular, in the first invention, the flat plate of the catalyst portion arranged so as to be zigzag is formed by alternately joining the end portions of a plurality of flat plates, so that stress on the flat plate is reduced. Since the end portions of the flat plate are joined alternately, the workability is improved. In addition, since the deodorizing passage is thinly formed by arranging flat plates in a zigzag, the degree of integration of the deodorizing passage is improved, the catalyst portion is compact, and the area of the closed portion is small, and the heat dissipation loss is suppressed.

  According to a third aspect of the present invention, in particular, in the second aspect of the present invention, the cross section of the deodorizing passage is obtained by bending the end portion of the flat plate by bending the end portion of at least one flat plate to the other flat plate side to be joined. Since it is substantially rectangular, the exhaust gas flows almost uniformly, the flat plate can be fully utilized, and the odor components of the exhaust gas are efficiently decomposed.

  In the fourth invention, in particular, in the first invention, the flat plate of the catalyst portion arranged so as to be zigzag is formed by alternately bending the belt-like flat plate a plurality of times, so that the stress on the flat plate is less. Workability is improved. In addition, since the deodorizing passage is thinly formed by arranging flat plates in a zigzag, the degree of integration of the deodorizing passage is improved, the catalyst portion is compact, and the area of the closed portion is small, and the heat dissipation loss is suppressed.

  In the fifth invention, in particular, in the fourth invention, the bent portion of the flat plate is bent substantially at a right angle and further bent in the same direction with the width of the deodorization passage, so that the cross section of the deodorization passage becomes substantially rectangular. Can flow almost uniformly and fully utilize the flat plate, and the odor components of the exhaust gas are efficiently decomposed.

  The sixth aspect of the present invention is the deodorizing passage in particular, even if the catalyst portion is thermally expanded by bending the end of the bent portion of the flat plate bent with the width of the deodorizing passage in the reverse direction. The passage width can be maintained by the spacer action due to the double folding, and the increase in pressure loss can be suppressed.

  According to a seventh aspect of the present invention, in particular, in the first or fourth aspect of the invention, the flat plates located in the upstream deodorization passage and the downstream deodorization passage are bent toward the introduction portion and the discharge portion, respectively. Since the set positioning can be performed, the passage width of the introduction part and the discharge part can be secured, and an increase in pressure loss can be suppressed.

  In an eighth aspect of the invention, in particular, in the third or fifth aspect of the invention, the bent portion of the flat plate is formed with a projecting portion so as to straddle the flat surface and the end thereof, thereby improving the rigidity of the bent portion of the catalyst portion. Therefore, the passage width of the deodorizing passage can be ensured and an increase in pressure loss can be suppressed.

  The ninth aspect of the invention is particularly the first aspect of the present invention, wherein the flat plate has a substantially trapezoidal catalyst part, and the catalyst part is equipped in a deodorizing container having a substantially trapezoidal cross section and a bottom with a bottom. The open side of the long side of the deodorization container is covered with a lid, and the closure part is arranged in the gap between the catalyst part and the deodorization container and the lid, so that the closure part that contacts the lid is pressed against the catalyst part. Since the closed portion in contact with the deodorization container is pressed against the deodorization container, the sealing property between the catalyst portion and the closed portion can be ensured.

  In the tenth invention, in particular, in the ninth invention, the end of the flat plate of the catalyst unit facing the bottom of the deodorizing container is formed in a curved shape, so that stress concentration at the end of the flat plate is alleviated and the flat plate Since the deformation is suppressed and the stress direction between the flat plate and the closed portion is stabilized, the sealing performance between the flat plate and the closed portion can be ensured.

  In the eleventh aspect of the invention, in particular, in the ninth aspect of the invention, the clogging portion is divided into a portion along the deodorization container and a portion along the lid, so that the catalyst portion lays the clogging portion on the deodorization container, and then the catalyst portion.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

(Embodiment 1)
1 to 3 show a deodorizing apparatus and a garbage disposal apparatus using the same in Embodiment 1 of the present invention.

  The garbage disposal apparatus shown in FIG. 1 includes a treatment container 31 for garbage 33 and is detachably provided in an inner container 32. A vertical stirring blade 34 is built in the bottom surface of the processing vessel 31. The agitation blade 34 is connected to a drive unit 35 including a drive motor and a transmission gear via a connection unit 36. The drying fan 37 facing the processing container 31 is provided on a lid 38 that covers the processing container 31 and opens and closes when the garbage 33 is thrown in. A drying heater 39 of a ring-shaped electric heater is disposed on the outer periphery. ing. The lid 38 is provided with an intake passage 40 that communicates the processing container 31 with outside air, and an exhaust passage 41 that communicates the processing container 31 and the exhaust fan 42.

  In the present embodiment, the deodorizing device 43 is provided in the middle of the exhaust passage 41. This deodorizing device 43 is provided with a catalyst (platinum, palladium) on a flat plate 50 with unevenness arranged so as to be zigzag so that the configuration can be understood more by referring to FIG. 2 and FIG. 3 in addition to FIG. A deodorizing passage 52 formed between the supported catalyst portion 49 and the adjacent flat plates 50 of the catalyst portion 49 and communicated with each other by a communication port 54, a closed portion 46 closing the open portion of the deodorizing passage 52, and a deodorizing passage The heating means 53 provided in 52, the introducing | transducing part 55 which has the channel | path inlet 56 connected to the upstream deodorizing channel | path 52, and the discharge part 58 which has the channel | path exit 57 connected to the downstream deodorizing channel | path 52 It is.

  In the present embodiment, the flat plate 50 of the catalyst portion 49 arranged in a zigzag manner is alternately joined (welded, brazed, welded, etc.) by bending the straight portion of the end portion 51 of each flat plate 50 by about 15 °. After that, the catalyst is supported. With this configuration, the stress on the flat plate 50 is small, and the workability is improved by alternately joining the end portions 51 of the flat plate 50. Further, the flat plate 50 is arranged in a zigzag manner so that the deodorizing passage 52 is thinly formed, the degree of integration of the deodorizing passage 52 is improved, the catalyst portion 49 is made compact, and the area of the closed portion 46 is narrowed to suppress heat dissipation loss. .

  The heating means 53 is formed of a U-shaped electric heater and, as shown in FIG. 2, is actually provided in a deodorizing passage 52A formed wide by bending the end portion 51A of the flat plate 50A.

  Further, as shown in FIG. 3, the introduction portion 55 covers a flat plate 50A that opens a passage inlet 56 that communicates with the upstream deodorization passage 52A, and the discharge portion 58 communicates with the downstream deodorization passage 52B. The flat plate 50B which opened the channel | path exit 57 is covered. The control unit (not shown) controls the drive unit 35, the drying fan 37, the exhaust fan 42, the drying heater 39, and the heating unit 53.

  The deodorizing device 43 will be described more specifically. As shown in FIG. 1, the flat plate 50 of the catalyst part 49 has a substantially trapezoidal shape. The catalyst part 49 is mounted on a deodorization container 44 having a substantially trapezoidal cross section and a bottom with a bottom. The open part of the long side of 44 is covered with a lid 45, and a blocking part 46 is arranged in the gap between the catalyst part 49, the deodorizing container 44 and the lid 45. The flat plate 50 of the catalyst unit 49 has a substantially trapezoidal shape as a whole. However, as illustrated, the end of the flat plate 50 facing the bottom of the deodorizing container 44 is formed in a curved shape, and the flat plate 50 is formed at the end of the flat plate 50. The stress concentration is alleviated, the deformation of the flat plate 50 is suppressed, the stress direction between the flat plate 50 and the closing portion 46 is stabilized, and the sealing performance between the flat plate 50 and the closing portion 46 is ensured.

  The closing part 46 is composed of a metal plate 47 having a thickness of about 0.1 mm and a ceramic material 48, and is divided into a closing part 46A along the deodorizing container 44 and a closing part 46B along the lid 45. The catalyst portion 49 is provided with a blocking portion 46 in the deodorizing container 44, and then the catalyst portion 49 is inserted. Finally, the blocking portion 46 is pressed against the catalyst portion 49 together with the lid 45 to secure a seal. It is improving.

  The operation of the garbage disposal apparatus configured as described above and the assembly of the deodorizing apparatus 43 will be described.

  When the lid 38 is opened and the garbage 33 is put into the processing container 31, and then the lid 38 is closed, the control unit starts the operation of the drying fan 37 and the exhaust fan 42, and at the same time, the drying heater 39 and the heating means. The energization to 53 is started. Further, since the control unit drives the driving unit 35 intermittently, the power of the driving unit 35 is transmitted to the stirring blade 34 via the connecting unit 36, and the stirring blade 34 rotates intermittently to stir the garbage 33. .

  Then, external air flows into the processing container 31 through the intake passage 40 by the suction action of the exhaust fan 42 (for example, 3 to 8 L / min). Next, convection is formed in the processing container 31 by the drying fan 37, and a large amount of hot air (for example, about 130 ° C.) whose temperature is increased by the drying heater 39 is lowered and collides with the wall surface of the processing container 31. The garbage 33 is dried. Subsequently, warm air containing water vapor generated from the garbage 33 rises in the center of the processing container 31 and reaches the drying fan 37. Thereafter, the warm air containing water vapor generated from the garbage 33 flows into the deodorizing device 43 through the exhaust passage 41 as exhaust gas (for example, about 100 ° C.).

  Then, the exhaust gas flowing through the introduction portion 55 is heated through the flat plate 50A whose temperature has been increased by radiation from the heating means 53 (for example, surface temperature 600 to 700 ° C.), and flows into the deodorizing passage 52A from the passage inlet 56. Subsequently, the exhaust gas flows along the entire length of the heating means 53. That is, since the exhaust gas is directly heated by heat transfer from the heating means 53, particularly the U-shaped portion where the calorific value is concentrated first, the exhaust gas rapidly increases in temperature (for example, 500 ° C.).

  Next, when the exhaust gas whose temperature has increased flows through the deodorization passage 52 (indicated by an arrow in FIG. 3), the temperature of the flat plate 50 is raised (for example, 450 ° C.) while contacting the catalyst supported on the flat plate 50. Components (eg trimethylamine) are efficiently decomposed. In addition, the flat plates 50A and 50B facing the introduction part 55 and the discharge part 58 also contribute to the deodorization of the exhaust gas. On the other hand, since a plurality of the deodorizing passages 52 are formed side by side so that the flat plates 50 are adjacent to each other, the degree of integration of the deodorizing passages 52 is improved and the size is reduced, and the area of the blocking portion 46 is narrow and heat dissipation loss is suppressed. The deodorized exhaust gas flows out from the discharge portion 58 to the exhaust passage 41 and is exhausted from the exhaust fan 42 to the outside.

  Next, the sealing property and assembling property of the deodorizing device 43 will be described. The assembling of the catalyst unit 49 is good because it is a stacked type in which the blocking unit 46A is laid in the deodorizing container 44, the catalyst unit 49 is inserted, and finally the blocking unit 46B and the lid 45 are arranged on the catalyst unit 49. . On the other hand, the sealing performance between the catalyst portion 49 and the closing portion 46 can be ensured by the lid 45 pressing the closing portion 46A against the catalyst portion 49, and then the catalyst portion 49 pressing the closing portion 46B against the deodorization container 44.

(Embodiment 2)
FIG. 4 shows a deodorizing apparatus according to Embodiment 2 of the present invention. The same elements as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The difference from the first embodiment is that, as the joint portion 60 of the catalyst portion 59, the end portion of at least one flat plate 61 is bent in a substantially right angle direction (75 °) to form a spacer 62 having a constant width, and further adjacent thereto. The tip 63 bent along the flat plate 61 is a contact portion with the adjacent flat plate 61. On the other hand, the spacer 65 is formed by bending the other end of the most upstream flat plate 61A so as to be in contact with the introduction portion 64. Similarly, the other end of the most downstream flat plate 61B is in contact with the discharge portion 66. The spacer 67 was formed by bending.

  Thereby, the end of at least one flat plate 61 is bent toward the other flat plate to be joined, so that the cross section of the deodorizing passage 52 becomes substantially rectangular. It can be used, and the odor component of exhaust gas decomposes efficiently. Moreover, since the passage widths of the introduction part 64 and the discharge part 66 can be secured by the spacers 65 and 67, an increase in pressure loss can be suppressed. Furthermore, joining can be performed easily by using the tip 63 bent along the adjacent flat plate 61 as the contact portion.

(Embodiment 3)
5 and 6 show a deodorizing apparatus according to Embodiment 3 of the present invention. The same elements as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The difference from the first embodiment is that a strip-shaped flat plate 69 is formed by alternately bending a plurality of times and a catalyst is supported on the flat plate 69. Thereby, the flat plate 69 of the catalyst unit 68 is configured to be zigzag.

  In the deodorizing apparatus, the heating means 53 directly heats the exhaust gas by heat transfer, so that the temperature of the exhaust gas rapidly increases. On the other hand, the heating means 53 heats the flat plate 69 by radiation. In particular, since the catalyst portion 68 is formed from a long strip-shaped flat plate, the temperature of the entire flat plate 69 also rises due to heat conduction. Next, while the exhaust gas whose temperature has increased flows through the deodorizing passage 52, the flat plate 69 is further heated to increase the temperature.

  That is, the catalyst supported on the flat plate 69 is activated and the odor component of the exhaust gas is sufficiently decomposed as the flat plate 69 becomes hotter than in the first embodiment. Further, since the deodorizing passage 52 is thinly formed by arranging the flat plate 69 in a zigzag manner, the degree of integration of the deodorizing passage is improved, the catalyst portion is made compact, the area of the closed portion is small, and the heat radiation loss is suppressed. On the other hand, since the catalyst portion 68 is formed by alternately bending a plurality of times, the stress on the flat plate 69 is small and the workability is good.

(Embodiment 4)
FIG. 7 shows a deodorizing apparatus according to Embodiment 4 of the present invention. The same elements as those in the first and third embodiments are denoted by the same reference numerals and the description thereof is omitted.

  In the present embodiment, as in the third embodiment, the strip-shaped flat plate 73 is formed by alternately bending a plurality of times, and the catalyst portion 70 is formed by supporting the catalyst on the flat plate 73. The bent portion 71 of the flat plate 73 is bent at a substantially right angle and further bent in the same direction with a deodorizing passage width so as to form a flat plate 73 of the catalyst unit 70 so as to be zigzag.

  As a result, since the cross section of the deodorizing passage 52 is substantially rectangular, the exhaust gas flows almost uniformly, and the flat plate 73 can be fully utilized, and the odor components of the exhaust gas are efficiently decomposed.

  Further, the bent portion 71 of the flat plate 73 forms a protruding portion 74 inward so as to straddle the flat surface 73a and its end portion.

  Thereby, since the rigidity of the bending part 71 of the catalyst part 70 improves, the channel width of the deodorizing channel | path 52 can be ensured and the increase in pressure loss can be suppressed.

(Embodiment 5)
FIG. 8 shows a deodorizing apparatus according to Embodiment 5 of the present invention. The same elements as those in the first to fourth embodiments are denoted by the same reference numerals and description thereof is omitted.

  In the present embodiment, the difference from the fourth embodiment is that the end (in this case, the lower end) of the bent portion 76 of the flat plate 77 bent at the width of the deodorizing passage 52 is cut and raised, and the width of the deodorizing passage 52 is reversed. It is bent. Spacers 78 and 79 are formed by bending the flat plate 77 and cutting and raising the end portions.

  Thereby, even if the catalyst part 75 is thermally expanded, the passage width of the deodorizing passage 52 can be maintained by the action of the spacers 78 and 79 by both folding, and an increase in pressure loss can be suppressed.

  As described above, the deodorization apparatus of the present invention and the garbage disposal apparatus using the same can be made compact and improve workability and assemblability, so that the deodorization apparatus can be used in combination with various apparatuses. As a garbage disposal device, it is optimal for household use in kitchens.
