(Embodiment 1)
FIG. 1 is a cross-sectional view of a deodorizing apparatus according to the first embodiment of the present invention.

  In FIG. 1, a deodorizing device 1 includes a fin 1 a formed on a metal pipe (not shown), a catalyst heater 2 mounted in the metal pipe, and a pipe that houses the fin 1 a and the catalyst heater 2. The case 3, the inlet pipe 4 for taking in air containing odorous gas into the case 3, the outlet pipe 5 for discharging the purified air from the case 3, the bottom surface of the case 3 and the catalyst heater in the center 2 is composed of a solitaire 6 which is a closed portion formed by projecting an inward flange 7 and a web 8 fixed to the upper end of the case 3 with a screw 9. The fin 1a is formed by spirally winding a metal thin plate around a metal pipe, or by fixing a plurality of circular metal thin plates each having a hole in the metal pipe, and supporting a catalyst on the metal thin plate.

  A fin fly 10 made of a thin metal plate is disposed in close contact with the outside of the fin 1a to form a purification path for odor gas with the fin 1a. A heat insulating material 11 is disposed between the fin fly 10 and the case 3 to prevent heat from being dissipated from the fin 1a. Case heat insulating materials 12 and 13 are provided outside the case 3. Odor gas such as exhaust gas is forcibly exhausted by a suction fan (not shown) communicating with the outlet pipe 5.

  The deodorizing apparatus 1 is mounted on a garbage processing machine (not shown) in order to reduce odor generated when drying or bioprocessing garbage, but it is mounted on a device generating odor. For example, the present invention is not limited to a garbage disposal machine, and has an effect of reducing odor.

  Next, the assembly method of the deodorizing apparatus 1 in this Embodiment is demonstrated.

  First, the inlet pipe 4 side (upstream side) of the catalyst heater 2 is passed through the flange 7 of the socoita 6 and the flange 7 is caulked and fixed to the catalyst heater 2 by welding or brazing. Next, the catalyst heater 2 is inserted from the upstream side of the case 3 where the inlet pipe 4 and the outlet pipe 5 are provided in advance (from the lower side in the figure), and at the same time, the socoita 6 is press-fitted into the end of the case 3, Accordingly, it is airtightly attached to the case 3 by means of caulking, welding, brazing or the like. Next, in a state where the fin sheath 10 and the heat insulating material 11 are wound around the outer periphery of the fin 1a, the metal pipe of the fin 1a is inserted through the catalyst heater 3 from above and stored in the case 3, and provided in the center of the web 8 The catalyst heater 2 is passed through the opening 8a, and finally the weber 8 is screwed to the case 3 with a screw 9 to complete the assembly.

  About the deodorizing apparatus 1 comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when the catalyst heater 2 is energized, the heat generated thereby is quickly transmitted to the fin 1a, and the catalyst carried on the surface of the fin 1a is activated. And the exhaust gas which flowed in from the inlet pipe 4 connected to the exhaust gas path | route (not shown) in an apparatus or an apparatus rises while passing through the hole provided in each metal thin plate spirally by the fin 1a, and the outlet pipe 5 Gas is exhausted from. During this time, when the catalyst carried on the surface of the fin 1a purifies the exhaust gas and exits from the outlet pipe 5, it becomes a clean gas.

  As described above, according to the present embodiment, since the catalyst heater 2 is directly fixed to the soy iterator 6 of the case 3, the reliability of the seal of the portion into which the untreated gas flows is improved and the number of parts is increased. As a result, the assembly can be simplified and inexpensively formed.

  Further, by increasing the height of the flange 7 of the socoita 6 as shown in FIG. 2, a portion for fixing the catalyst heater 2 vertically becomes longer, and a more accurate vertical degree can be obtained and assembling is easy. At the same time, the sealing effect is enhanced and the caulking width is increased, so that a high sealing effect can be maintained over a long period of time. Further, the catalyst heater 2 can be made less susceptible to the influence of a small amount of acid component contained in the dew condensation water contained in the exhaust gas.
