Discharged through. Air is introduced from the air supply pipe 14 into the exhaust fan 13 through the on-off valve 15.

This embodiment has the following effects.
(1) Since the amount and temperature of the exhaust gas introduced from the exhaust pipe (not shown) of the incinerator into the inlet pipe 2 varies depending on the type of waste and the incineration conditions, the deodorant / smoke body 7 is purified. The amount of exhaust introduced into the inlet pipe 2 can be adjusted by the on-off valve 3 in the inlet pipe 2 in accordance with the treatment capacity of the catalyst mass 9, and the catalyst temperature of the deodorant and smoke eliminating body 7 is set to 380 to 690, for example. Easy to adjust to ℃. At that time, if air is introduced into the inlet pipe 2 from the air introduction pipe 5, the temperature can be adjusted more easily. Therefore, the processing capacity of the deodorant and smoke eliminating body 7 can be improved.

  (2) The amount of exhaust discharged from the outlet pipe 10 can be adjusted by the on-off valve 12 in the outlet pipe 10 in accordance with the processing capacity of the purification catalyst mass 9 of the deodorant and smoke eliminating body 7, and It is easy to adjust the catalyst temperature of the smoke body 7 to, for example, 380 to 690 ° C. Therefore, the processing capacity of the deodorant and smoke eliminating body 7 can be improved.

  (3) The on / off valve 3 in the inlet pipe 2 and the on / off valve 12 in the outlet pipe 10 can be combined to adjust the residence time of the exhaust gas in the deodorant smoke eliminator 7, thereby eliminating the deodorant smoke. It is easy to adjust the catalyst temperature of the body 7 to, for example, 380 to 690 ° C. Therefore, the processing capacity of the deodorant and smoke eliminating body 7 can be improved.

(4) The air introduced from the air supply pipe 14 by adjusting the on-off valve 15 can prevent the exhaust fan 13 in the exhaust pipe 11 from being damaged by heat rise.
(5) By the secondary combustion chamber 16 provided in the exhaust pipe 11, the temperature of the exhaust can be raised to 800 ° C. or more and discharged, and generation of chemical substances such as dioxin can be suppressed.

  (6) The heater 4 can remove the moisture in the exhaust gas introduced from the inlet pipe 2 and reaching the deodorant / smoke body 7. At this time, the moisture of the exhaust can be further removed by passing the exhaust through the meandering passage 4 a and increasing the contact time between the exhaust and the heater 4. Note that the heater 4 may be stopped when the catalyst temperature becomes 380 ° C. or higher.

  (7) Since the deodorizing and smoke eliminating body 7 is formed by laminating the plurality of divided bodies 8, the processing capabilities of the divided bodies 8 can be changed from each other. For example, a treatment agent capable of treating sulfur that cannot be treated with a catalyst is placed in the lowermost divided body 8, and a purified catalyst mass 9 having a smaller size is placed in the upper divided body 8 to improve the processing efficiency.

(8) Since the purification catalyst mass 9 of the deodorant and smoke eliminating body 7 is formed in a gravel shape of 5 to 20 mm, the chemical substance flows through the complicated passage 9a between the aggregates of the purification catalyst mass 9 and the purification catalyst. A chemical substance also enters the pores 9b having different passage cross-sectional areas in the lump 9, and the contact area with the chemical substance is widened to increase the processing capacity. Further, in the deodorant / smoke body 7, the passage cross-sectional area of the passage 9 a and the pore 9 b of the passage 9 a is different due to the difference in the passage cross-sectional area between the passage 9 a between the purification catalyst lumps 9 and the pore 9 b in the purification catalyst lumps 9. The exhaust gas passes in the order of the larger one and the one having the smaller passage cross-sectional area, and a time difference is generated in the treatment by the passage 9a and the pores 9b, and the treatment can be performed without clogging due to their synergistic effect. When the purification catalyst mass 9 is manufactured, palladium, platinum, rhodium, alumina-ceria, zirconia, etc. are attached individually or in combination with each other and dried and calcined. Moreover, those baked obsidian and, Mo, Li, Zn, Cu , Ni, Co, Mn, MgO, Fe203, comprises _{TiO 2, CaO, Na20, K} 2 O, Al203, etc. SiO ₂ naturally at 1000 ° C. Odor and smoke can be removed by using only burned perlite. In this case, the treatment can be performed without applying heat at 380 ° C.

  (9) Moreover, the magnetic air supplied from the magnetic air supply pipe 18 to the inlet pipe 2 and the exhaust pipe 11 on the inlet side with respect to the deodorant and smoke eliminating body 17 in the inlet pipe 2 and the exhaust pipe 11, the fan 19 and the on-off valve By changing the amount of supply air by adjusting 20 or the like, oily substances such as coal tar, wood tar, and petroleum tar mainly containing hydrocarbons can be removed.

(10) The water placed in the chamber 6 provided around the case 1 can be warmed by the heat of the purification catalyst mass 9 or the heat of the heater 4 and used for various purposes.
For example, the following embodiment may be configured as follows.
In the embodiment, the heater 4 may be omitted.
-In the said embodiment, you may accommodate the aggregate | assembly of the purification | cleaning catalyst lump 9 in one box, without dividing the deodorant smoke-removing body 7 into the some division body 8. FIG.
