Since the connection part with the exhaust port of a stove and the connection part with a chimney are formed, the said flue gas processing apparatus can be easily attached and applied to the various stoves already provided. In addition, you may interpose an adjuster in the said connection part as needed. *
また、下部本体と上部本体は、対向部で係合させた構成であるから、容易に分離して内部のヒータ及び触媒の点検・保守及び交換等を行なうことができる。さらに、触媒の下部にヒータを配置したことにより優れた浄化効果を得ることができる。さらにまた、構成がシンプルであるから安価に提供できる。
Further, since the lower main body and the upper main body are engaged with each other at the opposing portions, they can be easily separated and the internal heater and catalyst can be inspected / maintained / replaced. Furthermore, an excellent purification effect can be obtained by arranging a heater below the catalyst. Furthermore, since the configuration is simple, it can be provided at a low cost. *
好適な実施の一形態として、前記下部本体及び上部本体の前記ヒータ及び触媒が配置された部分の内径を他の部分の内径よりも拡大した構成にすることができる。このように構成すれば、前記ヒータ及び触媒の配置された部分の内径が他の部分、すなわち、ストーブの排気口（との連結部）及び煙突（との連結部）の内径よりも拡大された結果、ストーブの排気口から供給された排煙の流速が拡大部において低下させられてヒータ及びヒータによる触媒の高温化により二次燃焼を十分に行なうことができる。
As a preferred embodiment, the inner diameter of the lower body and the upper body where the heater and catalyst are arranged can be made larger than the inner diameter of the other portions. If comprised in this way, the internal diameter of the part by which the said heater and the catalyst are arrange | positioned was expanded rather than the internal diameter of the other part, ie, the exhaust port (connection part with) and a chimney (connection part). As a result, the flow rate of the flue gas supplied from the exhaust port of the stove is reduced at the enlarged portion, and secondary combustion can be sufficiently performed by increasing the temperature of the heater and the catalyst by the heater. *
好適な実施の一形態として、前記ヒータ及び触媒の荷重を前記下部本体で保持した構成にすることができる。このように構成すれば、装置の安定設置が容易であり、また、設置後の荷重を下部本体及びストーブ側で受けて装置全体の安定を図ることができる。さらにヒータ及び触媒の点検・保守及び交換等を行なう場合にも上部本体を外して容易に行なうことができる。
As a preferred embodiment, the load of the heater and the catalyst can be held by the lower body. If comprised in this way, stable installation of an apparatus is easy, and the load after installation can be received in a lower main body and a stove side, and stability of the whole apparatus can be aimed at. Furthermore, when the inspection / maintenance / replacement of the heater and the catalyst is performed, the upper main body can be easily removed. *
さらに、好ましい一実施例として、前記ヒータを前記触媒に密着させた構成にすることができる。このように構成すれば、ヒータによって触媒の温度を急上昇させて燃料の着火時に発生する未燃焼ガスなどの完全燃焼を図ることができるとともに触媒の目詰まりを起こす物質を除去して目詰まりを防ぐことができる。
Furthermore, as a preferred embodiment, the heater can be in close contact with the catalyst.

さらに、好ましい一実施例として、前記触媒を複数段に配置した構成にすることができる。このように構成すれば、触媒の取り扱いが容易になるとともに、機能別に触媒を複数段に設けて排煙処理効果を上げることができるともにコストダウンを図ることができる。例えば、触媒を二段に配置した場合には、下側の触媒は低い温度の２５０℃から燃焼を始める必要があるためコストの高い貴金属が必要であるが、上側の触媒は下側の触媒の燃焼により高温化されるため５００℃から燃焼するコストの安い貴金属とすることができコストダウンを図ることができる。また、機能の低下した触媒を交互に交換することによりコストダウンを図ることができる。
Furthermore, as a preferred embodiment, the catalyst can be arranged in a plurality of stages. If comprised in this way, while handling of a catalyst becomes easy, a catalyst can be provided in several steps according to a function, and a smoke reduction effect can be raised, and cost reduction can be aimed at. For example, when the catalyst is arranged in two stages, the lower catalyst needs to start combustion from a low temperature of 250 ° C., and thus expensive noble metal is necessary, but the upper catalyst is the lower catalyst. Since the temperature is increased by combustion, a noble metal with low cost for burning from 500 ° C. can be obtained, and the cost can be reduced. Further, it is possible to reduce the cost by alternately exchanging the catalyst having a reduced function.

Further, a connecting portion 5 to the exhaust port 4 of the stove 3 is formed at the lower end of the lower main body 1, and a connecting portion 8 to the intake port 7 of the chimney 6 is formed at the upper end of the upper main body 2.
さらに、前記一体に構成された下部本体１及び上部本体２の内部には、ヒータ９及び該ヒータ９の上部に触媒１０が二段に配置される。
Further, the heater 9 and the catalyst 10 are arranged in two stages above the heater 9 inside the integrally formed lower main body 1 and upper main body 2.
なお、図面実施例では、前記ヒータ９及び触媒１０が配置された部分の下部本体1及び上部本体２の内径を他の部分の内径よりも拡大している。また、前記ヒータ９及び触媒１０の荷重を前記下部本体１で保持した構成としている。
In the embodiment of the drawings, the inner diameters of the lower main body 1 and the upper main body 2 in the portion where the heater 9 and the catalyst 10 are disposed are larger than the inner diameters of the other portions. Further, the load of the heater 9 and the catalyst 10 is held by the lower main body 1.
なお、前記下部本体1及び上部本体２としては耐熱性を有する金属、好ましくは鋳物が用いられる。また、ヒータ９は電熱線からなる電気ヒータが用いられる。
The lower main body 1 and the upper main body 2 are made of a metal having heat resistance, preferably a casting. The heater 9 is an electric heater composed of a heating wire.
前記触媒１０は耐熱性を有する網目状の金属にプラチナ、ロジウム、パラジウム等の貴金属をコーティングして構成され、前記本体内に一段に設けることのほか、触媒の機能別に複数段に設けて排煙処理効果を上げることもできる。
The catalyst 10 is formed by coating a noble metal such as platinum, rhodium, palladium, etc. on a network metal having heat resistance. In addition to being provided in the main body, the catalyst 10 is provided in multiple stages according to the function of the catalyst. A processing effect can also be improved.
前記下部本体１と上部本体２の係合は、分離可能であり且つ緊密に係合することが必要である。図面実施例では、前記下部本体１の上縁部１１の内周に段部１２を形成し、前記上部本体２の下縁部１３の内周に段部１４を形成し、該段部１４と前記下部本体１の上縁部１１を係合させている。その他の凹凸係合であってもよい。

In the illustrated embodiment, a step 12 is formed on the inner periphery of the upper edge 11 of the lower body 1, and a step 14 is formed on the inner periphery of the lower edge 13 of the upper body 2. The upper edge 11 of the lower body 1 is engaged. Other uneven engagement may be used.
そして、前記下部本体１の上縁部１１の内周に形成した前記段部１２に前記触媒１０が載置及び保持されている。さらに触媒１０の下方に前記ヒータ９が配置される。
The catalyst 10 is placed and held on the step 12 formed on the inner periphery of the upper edge 11 of the lower main body 1. Further, the heater 9 is disposed below the catalyst 10.
つぎに前記構成の排煙処理装置の一使用例を説明する。
Next, an example of use of the smoke treatment apparatus having the above-described configuration will be described.
下部本体１の下端の連結部５がストーブ３の排気口４と連結され、上部本体２の上端の連結部８が煙突６の吸気口７と連結される。
A connecting portion 5 at the lower end of the lower body 1 is connected to the exhaust port 4 of the stove 3, and a connecting portion 8 at the upper end of the upper body 2 is connected to the intake port 7 of the chimney 6.
つぎに、ストーブ３に燃料の石炭が投入され、着火１０分前にヒータ９に通電して触媒１０を加熱する。このことは、石炭の着火時に発生する未燃焼ガスを触媒１０により燃焼させるためである。
Next, coal of fuel is put into the stove 3 and the heater 10 is energized 10 minutes before the ignition to heat the catalyst 10. This is because the catalyst 10 burns unburned gas generated during coal ignition.
前記ヒータ９に通電することにより、上部本体２及び煙突６内に上昇気流が発生し、ストーブ３の吸気口（図示せず）から外気の吸入が始まり石炭への着火が行なわれ易くなります。
When the heater 9 is energized, an upward air flow is generated in the upper body 2 and the chimney 6, and the intake of outside air starts from the inlet (not shown) of the stove 3, making it easy to ignite the coal.
一方、ストーブ内では着火直後から未燃焼ガスが発生します。しかし、ストーブ３の排気口４から連結部５を介して下部本体１内に供給された未燃焼ガスはヒータ９により加熱及び加熱された触媒１０に接触して二次燃焼させられます。
On the other hand, unburned gas is generated immediately after ignition in the stove. However, the unburned gas supplied from the exhaust port 4 of the stove 3 into the lower main body 1 through the connecting portion 5 is heated by the heater 9 and contacts the heated catalyst 10 for secondary combustion.
本発明では、前記ヒータ９及び触媒１０の配置された部分の内径を他の部分の径よりも拡大しており、拡大部では未燃焼ガスの流速が遅くなり二次燃焼が有効に行なわれます。
In the present invention, the inner diameter of the portion where the heater 9 and the catalyst 10 are arranged is larger than the diameter of the other portions, and the flow rate of the unburned gas becomes slower in the enlarged portion, and secondary combustion is effectively performed. .
さらに、好ましい使用例として、触媒１０の加熱温度を検知してヒータ９への電力供給を制御し、電力の消費を抑えることが考えられます。例えば、触媒１０が機能し始めると５００℃以上になります。その後、未燃焼ガスが２７０℃前後で通過すれば触媒１０は機能し続けます。
Furthermore, as a preferred use case, it is conceivable to control the power supply to the heater 9 by detecting the heating temperature of the catalyst 10 to suppress the power consumption. For example, when the catalyst 10 starts functioning, it will be over 500 ℃. After that, if unburned gas passes around 270 ℃, the catalyst 10 will continue to function.
そこで、触媒１０の上部の加熱温度を検知し、５００℃の温度を３分間以上継続した場合にはヒータ９への通電を自動的に断ち、その後、触媒１０の温度が３００℃以下になった場合にヒータ９への通電を再開し、この通電制御を自動的に行なうことにより電力の消費を抑えることができます。
Therefore, when the heating temperature of the upper part of the catalyst 10 is detected and the temperature of 500 ° C. is continued for 3 minutes or longer, the power supply to the heater 9 is automatically cut off, and then the temperature of the catalyst 10 becomes 300 ° C. or lower. In such a case, the power supply to the heater 9 can be resumed, and this power supply control can be performed automatically to reduce power consumption.
