本発明は有害悪臭物質含有ガスの脱臭燃焼装置に関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a deodorizing combustion device for gas containing harmful malodorous substances.

、触媒を全く用いず該ガスを高温燃焼火災炉に導入して
直接燃焼させる直燃法か、又は助燃バーナにより該ガス
を必要な温度まで上昇させた後、白金等の触媒に接触さ
せ燃焼させる触媒燃焼法がある。Conventionally, in order to remove harmful malodorous substances from gas containing harmful malodorous substances, the gas is introduced into a high-temperature combustion fire furnace and directly combusted without using any catalyst, or the gas is heated to the required temperature using an auxiliary combustion burner. There is a catalytic combustion method in which the material is brought into contact with a catalyst such as platinum and then combusted.

すため、処理ガス量が増えると共に燃焼排ガス中の触媒
毒（例えば、白金に対しては５Ｏ３）も通過させる結果
となるという問題点をか＼えていた。In the conventional direct combustion method, in order to completely decompose and oxidize harmful malodorous substances, the temperature inside the combustion furnace is kept high and uniform (650 to 800 degrees Celsius), and the contact time with the flame is ensured (0.3 to 0 degrees Celsius).
, 5 seconds), and therefore, depending on the throughput, the necessary furnace size, fuel consumption, etc. are severely limited, and fuel consumption tends to increase. In addition, although the conventional catalytic combustion method consumes less fuel than the direct combustion method, it is still necessary to raise the temperature of the entire gas volume through auxiliary combustion until the temperature at which the catalyst is activated (approximately 350°C) is reached. In order to raise the temperature uniformly, there are certain restrictions such as the number and arrangement of auxiliary burners, and the combustion exhaust gas also passes through the catalyst layer together with the suction gas (processed gas), so as the amount of treated gas increases, the catalyst in the combustion exhaust gas This poses a problem in that poisons (for example, 5O3 for platinum) are also allowed to pass through.
本発明は上記技術水準に鑑み、従来方式の欠点を解消し

である。The combustion exhaust gas is exhausted to the exhaust chamber 4 through the porous ceramic exhaust wall 9, and the exhaust wall 9, like the furnace wall 7, is exhausted from the furnace 8.
The temperature inside the furnace 8 is made high and uniform by radiant heat transfer. The exhaust gas exiting from the exhaust wall 9 is returned to the original sampling location duct 1 via the exhaust line 10 after preheating the gas containing harmful malodorous substances in the indirect heat exchanger 5. In addition, in the figure, 1

This is to eliminate the problem by providing a fan on the downstream side if excessive pressure or problems occur (for example, the pressure inside the furnace 8 becomes extremely high).
助燃バーナの周囲を多孔質セラミックで囲み炉壁とする
ことにより、炉壁を通じて有害悪臭物質含有ガスを加熱
炉に送り込むことができる。By surrounding the auxiliary combustion burner with porous ceramic to form the furnace wall, gas containing harmful malodorous substances can be sent into the heating furnace through the furnace wall.
又炉内は炉壁の輻射伝熱により高温、かつ均質化される
