BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) As shown in FIG. 2, the deodorizing device of this embodiment includes a container body 1 made of metal and formed in the shape of a rectangular parallelepiped box. A ventilation port 1a (see FIG. 1) is provided at one of the longitudinal ends of the body 1 (the upper surface in FIG. 2) in the longitudinal direction, and the ventilation pipe 1 is provided at the ventilation port 1a. Are connected.
Collar pieces 1b are provided on the peripheral edges of both end surfaces of the body 1 in the longitudinal direction.
Is projected. A plurality of bolt holes 1c through which bolts pass through the front and back of the flange piece 1b are provided along the peripheral edge of the body 1. For example, when the deodorizing device of the present embodiment is used in a device such as a food waste disposer, the collar piece 1b is used to fix the body 1 to the main body of the device. The brim piece 1b on the side closer to the vent hole 1a has a connecting piece 11 having a shape corresponding to the brim piece 1b.
b is a bolt 12 penetrating the collar piece 1b and the connecting piece 11b.
And the nut 13 (see FIG. 5).
The connecting piece 11b is provided on the peripheral edge of the opening side of the rectangular box-like connecting tube 11 having one open surface. Also,
An exhaust pipe 11a, which communicates with the inside and outside of the connecting pipe 11, is provided at the central portion of the surface of the connecting pipe 11 away from the connecting piece 11b so as to project to the outside of the connecting pipe 11.

Next, the detailed configuration of this embodiment will be described with reference to FIG. The arrows in the figure indicate the general direction of the air flow. An inner pipe 2 extending along the longitudinal direction of the body 1 is provided inside the body 1, and one end of the inner pipe 2 is connected to an end surface of the body 1 on the side closer to the ventilation hole 1a in the longitudinal direction. And communicates with the inside of the connecting pipe 11. The other end of the inner pipe 2 is a catalyst portion 2a in which the catalyst 5 is arranged. The catalyst 5 is
It is a honeycomb body on which a substance such as platinum that promotes the oxidation of odorous substances is deposited. In addition, a heater 4 is arranged inside the body 1 at the end portion on the side away from the ventilation port 1 a in the longitudinal direction with a gap from the catalyst 5.

A first flow path extending from the vent 1a to the heater 4 is formed along the inner tube 2 between the body 1 and the inner tube 2,
A second flow path is formed inside the inner tube 2. The gas containing odor is introduced from the ventilation port 2a through the intake pipe 10, passes through the first flow path, is heated by the heater 4, and flows into the catalyst portion 2a of the inner pipe 2. Then, after being deodorized by the catalyst 5, it passes through the second flow path, flows into the connecting pipe 11, and is discharged to the outside of the deodorizing device through the exhaust pipe 11a. The gas passing through the second flow path has a higher temperature than the gas passing through the first flow path after being heated by the heater 4, and the gas passing through the tube wall of the inner tube 2 and the gas flowing through the first flow path The gas in the second flow channel exchanges heat. That is, in this embodiment, the portion of the inner pipe 2 that is farther from the heater 4 than the catalyst 5 functions as the heat exchange portion 2b.

Even if there is a difference in the inner tube 2, since the inner tube 2 can freely expand and contract with respect to the body 1, compared to the case where the inner tube 2 is supported by the body 1 at both ends,
The strain generated at the joint between the inner tube 2 and the body 1 is reduced,
Therefore, the deodorizing device is less likely to be damaged. Further, in the conventional example, a deodorizing unit body 6 different from the body 1 in which the inner tube 2 is housed
Since the heater 4 and the catalyst 5 are housed in the housing and a pipe connecting the body 1 and the deodorizing unit body 6 is required, it is difficult to reduce the size, but in the present embodiment, the inner pipe 2 is used. Heater 4
Since the catalyst 5 and the catalyst 5 are housed in one container 1, the size can be easily reduced. Further, since the heat is transmitted from the inner side to the outer side of the inner pipe 2 by flowing the gas from the first flow passage to the second flow passage, the heat is transmitted from the outer side to the inner side of the inner pipe 2 more than Since the temperature difference between the inside and outside of the body 1 is small, the heat escaping to the outside of the body 1 is reduced, and therefore the thermal efficiency is improved.

(Embodiment 2) In this embodiment, FIG.
As shown in FIG. 2, the heat exchange section 2b extends along the longitudinal direction of the body 1 and has a plurality of (4 in FIG. 2) straight tubular heat distributions arranged at equal intervals around the center line of the inner tube 2. Exchange tube 2

Since it is bent a plurality of times so as to hit the baffle plate, the airflow formed in the first flow path is more likely to come into contact with the heat exchange tube 2c as compared with the case where the baffle plate 8 is not provided, and the heat exchange efficiency is further improved.

Although each baffle plate 8 is fixed to the body 1 and not to the heat exchange pipe 2c, the inner pipe 2
It suffices that it can be freely expanded and contracted with respect to the body 1, and for example, each baffle plate 8 may be fixed to the heat exchange tube 2c but not fixed to the body 1.

According to the above configuration, the air flow in the first flow path is formed as shown by the arrow in FIG.
As compared with the case where the air flow is alternately passed to both ends of the baffle plate 8 along the lateral direction of the body 1 as indicated by the arrow in (a),
Since the temperature difference between the front and back of the baffle plate 8 near the inner wall of the body 1 becomes smaller, the heat transferred from the downstream side to the upstream side of the first flow path via the baffle plate 8 decreases, and therefore the thermal efficiency is further improved. improves.

Although each first baffle plate 8a is fixed to the body 1 and not to the heat exchange tube 2c, it is sufficient if the inner tube 2 can freely expand and contract with respect to the body 1. ,
For example, each first baffle plate 8a may be fixed to the heat exchange tube 2c but not to the body 1.

(Fifth Embodiment) As shown in FIG. 9, the deodorizing device according to the fifth embodiment has a plurality of pieces (in the figure, extending through the baffle plates 8a, 8b along the tube axis of the heat exchange tube 2c).

The width dimension of each guide plate 9 along the direction in which is aligned is set to be larger than the width of the gap between the adjacent heat exchange tubes 2c.
Other configurations are similar to those of the fourth embodiment.

When the guide plate 9 is not provided as in the fourth embodiment, the air flow passes between the adjacent heat exchange tubes 2c as shown by the arrow in FIG. 10 (a). In this case, on the peripheral surface of the heat exchange tube 2c, it is near the facing portion of each pair of adjacent heat exchange tubes 2c that contributes to heat exchange. On the other hand, when the guide plate 9 is provided as in the present embodiment, the airflow flowing into the through hole 8c of the first baffle plate 8a is as shown in FIG.
As shown by the arrow in (b), it passes through the gap between the guide plate 9 and the heat exchange tubes 2c and flows along the circumferential direction of each heat exchange tube 2c. Therefore, compared with the case where the guide plate 9 is not provided,
The area of the peripheral surface of the heat exchange tube 2c that contributes to heat exchange becomes larger, and the efficiency of heat exchange is further improved.

(Embodiment 6) In this embodiment, as shown in FIG. 11, a first baffle plate 8a and a second baffle plate 8 are provided.

That is, since the gas whose temperature has risen due to heat exchange stays near the first baffle plate 8a, heat leaks to the outside of the body 1 through the first baffle plate 8a. On the other hand, according to the present embodiment, of the front and back surfaces of the first baffle plate 8a, the downstream surface of the first flow path has a downstream side of the first flow path on the downstream side of the first flow path. Since the inclined surface 8d that is inclined to is formed, the airflow is formed along the inclined surface 8d as shown in FIG. The efficiency of heat exchange is further improved as compared with the case where the heat exchanger is not provided.

[0033]

According to the invention of claim 1, since the inner pipe is cantilevered by the container, the inner pipe can freely expand and contract with respect to the container, and therefore the gas in the first flow path is Even if the expansion of the inner tube and the expansion of the container are different, such as when the temperature difference between the gas in the second flow path and the gas in the second flow path is large, compared to the case where both ends of the inner tube are connected to the container, Since the strain generated at the joint with the body is small, the deodorizing device is less likely to be damaged.

According to the second aspect of the invention, heat is transmitted from the inner side of the inner pipe to the outer side by flowing the gas from the first flow passage to the second flow passage. Compared with the case where the heat is transferred to the inside of the body, the temperature difference between the inside and the outside of the body is reduced, and the leakage of heat to the outside of the body is reduced, so that the thermal efficiency is improved.

According to the invention of claim 6, the first baffle plate and the second baffle plate are alternately arranged along the tube axis of the heat exchange tube, so that the heat exchange section is sandwiched between the baffle plates. Compared to the case where two locations are alternately opened, the temperature difference between the gas near the front and back sides of the portion of the baffle that is far from the edge where the air flow passes is smaller, so that the first flow path through the baffle is used. The heat transferred from the downstream side to the upstream side is reduced, and thus the efficiency of heat exchange is improved.

According to the invention of claim 7, the gas is formed along the circumferential direction of the heat exchange tube through the gap between the induction plate and the heat exchange tube.

As compared with the case where there is no airflow, the separation of airflow is less likely to occur, that is, the heat leaked from the gas staying near the first baffle plate through the first baffle plate to the outside of the body due to the separation of the airflow is reduced. Therefore, the efficiency of heat exchange is improved.
