Description

  The present invention relates to a deodorizing apparatus for decomposing odor components and a garbage disposal apparatus using the same.

Conventionally, a deodorization apparatus used for a garbage disposal apparatus or the like includes a catalyst deodorization unit that communicates with an exhaust gas exhaust passage, and the catalyst deodorization unit spirally winds a strip-shaped metal thin plate around a cylindrical catalyst container. It is known to have a built-in catalyst fin having a platinum catalyst supported on its surface and a catalyst heater for heating the catalyst fin (see, for example, Patent Document 1).
Japanese Patent No. 3334462

  However, in the conventional configuration, there is no heating source in the exhaust passage upstream of the catalyst deodorizing unit, and the temperature of the exhaust passage is 100 ° C. or lower. In particular, in the case of outdoor installation in winter, the temperature of the exhaust passage becomes very low. As a result, water droplets are generated from the exhaust gas containing steam on the inner wall of the exhaust passage. Odor components contained in the exhaust gas are dissolved in the water droplets. After that, a large number of water droplets gather and flow into the catalyst deodorizing part together with the exhaust gas, and come into contact with the catalyst fins. The water droplets that have grown into large particles evaporate all at once with the catalyst fins and take away the latent heat of evaporation from the catalyst fins, so that the temperature of the catalyst fins rapidly decreases. As a result, since the temperature of the catalyst fin is equal to or lower than the catalyst activation temperature (about 400 ° C.), there is a problem that the deodorizing performance is deteriorated. In addition, the exhaust gas becomes a large amount due to the suddenly generated steam. That is, since a large amount of odor components flow into the deodorization device, there is a problem that the odor is discharged for several seconds without being completely deodorized.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a deodorizing apparatus that prevents a decrease in deodorizing performance due to water droplets and maintains the deodorizing performance, and a garbage disposal apparatus using the same.

An evaporating section for evaporating water droplets in the exhaust passage is provided.

  As a result, the generated water droplets are gradually evaporated in the evaporation section, and only the exhaust gas flows into the catalyst container. Therefore, the temperature of the catalyst fin is maintained at the catalyst activation temperature (about 400 ° C.) or higher, and the deodorizing performance by the water droplets Prevents decline and maintains deodorization performance.

  Moreover, the garbage processing apparatus using the deodorizing apparatus of the present invention is optimal for home kitchen use because it maintains the deodorizing performance and does not discharge odor.

It is composed of a protruding introduction passage. As a result, water droplets generated in the exhaust passage gather and flow into the evaporation chamber together with the exhaust gas, and adhere to and accumulate on the outer surface of the catalyst container, the inner surface of the evaporation container, and the outer surface of the introduction passage. On the other hand, the temperature of the evaporation container and the introduction passage is raised to 100 ° C. or more by the catalyst heating means via the catalyst fin and the catalyst container. As a result, the water droplets in the evaporation chamber gradually evaporate again, and the amount of exhaust gas containing steam is leveled, so that the deodorizing device can be prevented from temporarily exceeding the deodorizing capacity. Moreover, only the exhaust gas containing steam flows into the catalyst container. That is, it is possible to prevent water droplets from evaporating from the catalyst fins and take away latent heat of evaporation, and the temperature of the catalyst fins is maintained at the catalyst activation temperature or higher, so that the deodorizing performance can be maintained. At this time, heat recovery is performed by using the heat escaping from the catalyst container to the outside as latent heat of evaporation.

  In a third aspect of the invention, in particular, in the first aspect of the invention, the evaporating section communicates with the evaporating chamber formed by connecting the exhaust passage to the catalyst container heated by the catalyst heating means, and projects into the evaporating chamber. And the introduction passage. As a result, the deodorizing performance can be maintained in the same manner as in the second invention. In addition, an exhaust passage is used as the evaporation chamber, and no additional evaporation container is required, thereby reducing costs.

The boundary between the exhaust passage and the introduction passage is connected to the catalyst container, and the introduction passage communicates with the catalyst container heated by the catalyst heating means. As a result, the deodorizing performance can be maintained in the same manner as in the second invention. In addition, the introduction passage is formed by using the exhaust passage, and no separate evaporation container or other parts are required, so that the cost can be reduced.

  According to a fifth aspect of the invention, in particular, in the first aspect of the invention, the evaporation section is configured by an evaporation chamber in which the exhaust passage is formed in an S shape, and the evaporation chamber is disposed in the vicinity of the catalyst container heated by the catalyst heating means. It is a thing. As a result, the deodorizing performance can be maintained in the same manner as in the second invention. Further, the configuration of the evaporation chamber only forms an S shape in the middle of the exhaust passage, and the configuration is simple, and there is no need for a separate evaporation container or other parts, so that the cost can be reduced.

  In a sixth aspect of the invention, in particular, in the first aspect of the invention, the evaporating section is constituted by an evaporating chamber formed in the middle of the exhaust passage in a U shape, and the evaporating chamber is disposed in the vicinity of the catalyst container heated by the catalyst heating means. It is a thing. As a result, the deodorizing performance can be maintained in the same manner as in the second invention. Further, the same effect as in the fifth invention can be obtained.

  In a seventh aspect of the invention, in particular, in the first aspect of the invention, the evaporating section is composed of an evaporating chamber formed by projecting the bottom surface of the catalyst container to which the exhaust passage is connected downward. As a result, the deodorizing performance can be maintained in the same manner as in the second invention. Further, the same effect as in the fifth invention can be obtained.

  According to an eighth aspect of the invention, in particular, in the seventh aspect of the invention, the catalyst heating means faces the evaporation chamber of the catalyst container, so that the evaporation section is directly heated by the radiation of the catalyst heating means and rapidly rises in temperature, and Since the temperature is high, the water droplets flowing into the evaporation part can be evaporated even if a substance with a high boiling point such as oil is contained. In addition, water droplets drifting in the exhaust gas can be directly evaporated by the catalyst heating means, the temperature of the catalyst fin is stably maintained above the catalyst activation temperature, and the deodorizing performance can be maintained.

As a result, water droplets generated in the exhaust passage concentrate and flow into the evaporation chamber together with the exhaust gas, adhere to the vertical surface of the catalyst container and the inner surface of the evaporation container, and accumulate in the lower portion of the evaporation chamber. Further, since the large water droplets that have flowed into the evaporation chamber do not naturally accumulate on the vertical surface of the catalyst container, they do not flow directly into the catalyst container from the inlet. That is, since the introduction passage is unnecessary, the cost can be reduced. The deodorizing performance can be maintained in the same manner as in the second invention.

  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)
FIG. 1 shows a deodorizing apparatus and a garbage disposal apparatus using the same in Embodiment 1 of the present invention.

  As shown in the figure, the processing container 21 of the garbage 23 is detachably provided in the inner container 22 and has a vertical stirring blade 24 built in the inner bottom surface. The stirring blade 24 is connected to a drive unit 25 including a drive motor and a transmission gear via a connection unit 26. A drying fan 27 facing the processing container 21 is provided on a lid 28 that covers the processing container 21 and opens and closes when the garbage 23 is thrown in, and a drying heater 29 of a ring-shaped electric heater is disposed on the outer periphery. ing. The lid 28 is provided with an intake passage 30 that communicates the processing container 21 with the outside air and an exhaust passage 31 that communicates the processing container 21 and the exhaust fan 32.

  The deodorizing device 33 includes a catalyst container 34 provided in the middle of the exhaust passage 31 into which exhaust gas flows, and an evaporation unit 37 provided on the upstream side of the catalyst container 34 to evaporate water droplets in the exhaust passage 31. The catalyst container 34 is formed by spirally winding a strip-shaped metal thin plate, and has a catalyst fin 35 carrying a catalyst (platinum and palladium) on its surface and a catalyst heating means 36 of an electric heater. . In this embodiment, the evaporation unit 37 is configured by winding an evaporation heater 38 of a cord-shaped electric heater around the exhaust passage 31 on the upstream side of the deodorizing device 33. The control unit (not shown) controls the drive unit 25, the drying fan 27, the exhaust fan 32, the drying heater 29, and the evaporation heater 38.

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

  When the lid 28 is opened and the garbage 23 is put into the processing container 21 and then the lid 28 is closed, the control unit starts the operation of the drying fan 27 and the exhaust fan 32, and simultaneously the drying heater 29 and the catalyst heating. Energization of the means 36 and the evaporation heater 38 is started. Moreover, since the control unit drives the drive unit 25 intermittently, the power of the drive unit 25 is transmitted to the stirring blade 24 via the connecting unit 26, and the stirring blade 24 rotates intermittently to stir the garbage 23. .

  And by the suction effect | action of the exhaust fan 32, external air flows in into the process container 21 through the intake passage 30 (for example, 3-8 L / min). Next, convection is formed in the processing container 21 by the drying fan 27, and a large amount of warm air (for example, about 130 ° C.) whose temperature is increased by the drying heater 29 is lowered and collides with the wall surface side of the processing container 21. The garbage 23 is dried. Subsequently, warm air containing water vapor generated from the garbage 23 rises in the center of the processing container 21 and reaches the drying fan 27.

  On the other hand, warm air containing water vapor generated from the garbage 23 flows into the exhaust passage 31 as exhaust gas (for example, around 100 ° C.), but there is no heating source in the exhaust passage 31 upstream of the deodorizing device 33. The temperature of the exhaust passage 31 is lower than 100 ° C., and water droplets A are generated on the inner surface of the exhaust passage 31. The many water droplets A gather and flow into the evaporation section 37 together with the exhaust gas. Since the evaporating part 37 is heated by the evaporating heater 38 and the temperature is raised, the water droplet A that has flowed into the large particles evaporates instantaneously. That is, the exhaust gas does not contain water droplets A, and is heated by the evaporation unit 37 and then flows into the deodorizing device 33 and flows along the catalyst fins 35. As a result, the catalyst fins 35 heated by the catalyst heating means 36 are not deprived of the latent heat of vaporization by the water droplets A, are maintained at the catalyst activation temperature (for example, 400 ° C. or higher), and the exhaust gas temperature is also increased in advance. Since it is warm, the catalyst of the catalyst fin 35 sufficiently decomposes the odor component (for example, trimethylamine) of the previous exhaust gas. The deodorized exhaust gas is exhausted from the exhaust fan 32 to the outside.

  As described above, in the present embodiment, the generated water droplets are gradually evaporated by the evaporation unit 37, and only the exhaust gas flows into the catalyst container 34. Therefore, the temperature of the catalyst fin 35 is the catalyst activation temperature (about 400 ° C.). It is kept above, prevents the deodorization performance from being lowered by water droplets, and maintains the deodorization performance.

Thus, it is possible to prevent the water droplet A from jumping into the catalyst container 42 from the introduction passage 47. In particular, when the garbage processing capacity is large or in a low temperature atmosphere, a large amount of water droplets B are generated and collected on the evaporation chamber 46, that is, on the outer surface of the catalyst container 42.

As a result, the water droplets A and B in the evaporation chamber 46 gradually evaporate again, and the amount of exhaust gas containing steam is leveled, so that the deodorizing device 39 can be prevented from temporarily exceeding the deodorizing capacity. That is, the peak of the exhaust gas flowing into the catalyst container 42 can be suppressed. Further, only the exhaust gas containing steam flows into the catalyst container 42. That is, it is possible to prevent the water droplets A from evaporating at the catalyst fins 40 and take away latent heat of evaporation, and the temperature of the catalyst fins 40 is maintained at the catalyst activation temperature or higher, so that the deodorizing performance can be maintained.

  The evaporation unit 44 may be the outer surface or the vertical surface of the bottom surface of the catalyst container 42. In short, it is sufficient that water droplets accumulate and the water droplets do not directly enter the deodorizing apparatus.

  As described above, in the present embodiment, it is possible to prevent water droplets from evaporating at the catalyst fins 40 and take away latent heat of evaporation, and the temperature of the catalyst fins 40 is maintained at or above the catalyst activation temperature, so that the deodorizing performance can be maintained. .
