害物となるが、その防止策としての従来技術には、次の
ようなものがある。The smoke and odor generated when Nuclap, which contains a large amount of combustible material, is preheated using high-temperature exhaust gas from the arc furnace becomes secondary pollution due to the correlation with the amount of combustible material and scrap preheating temperature. , Conventional techniques as preventive measures include the following.
(ん スクラップ予熱後の排ガスをリサイクルファンに
よシ、電炉に近接したダクト等の面温排ガスと合流燃焼
除去する方法。(N) A method in which the exhaust gas after preheating the scrap is transferred to a recycling fan, and then combined with surface temperature exhaust gas from a duct, etc. close to the electric furnace, and burned and removed.

る。The disadvantages of this method are: (1) Low-temperature gas (100 to 1
50℃) and electric furnace exhaust gas, it is necessary to maintain the mixed gas temperature at around 600℃, so scrapping is required.
It is necessary to limit and control the amount of gas introduced into the preheating device to within 50% of the electric furnace exhaust gas, which reduces the preheating effect by the scrap preheating device by half. Therefore, labor-saving effects are halved.

。(2) Since the amount and temperature of the gas generated in an electric furnace vary widely depending on operating conditions and furnace conditions, the mixed gas of the exhaust gas after preheating the scrap and the electric furnace exhaust gas is used to burn and decompose the smoke and odor. The method of controlling the conditions for removal is uncertain and is incomplete as a measure to prevent secondary publicity.

ァンOGによって接続ダクト圓に流入する。At this time, the high temperature exhaust gas from the arc furnace (1) preheats the scrap in the scrap preheating device (8). After this preheating, the exhaust gas contains dust and organic substances adhering to the scrap, and the organic substances are evaporated into the exhaust gas. In the exhaust gas containing secondary pollutants in this way, only dust is captured in the baghouse u3. The evaporated organic matter passes through the baghouse (13) and flows into the connecting duct circle by the axial fan OG.
