Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 酸性ガスの除去率を上げようとすれば、多量 の消石灰粉を吹き込まなければならない。また、排ガス が排出されるまでの間に、有害な有機塩素化合物が漸減 する度合いが不十分である。 【解決手段】 廃棄物焼却炉1から排出される排ガスを 減温塔2で120℃〜200℃に冷却し、この排ガスを 第一の集塵機3へ導入して媒塵を除去する処理を行い、 次いで、煙道7内で、排ガス中に消石灰粉を吹き込み、 この消石灰粉が吹き込まれた排ガスを第二の集塵機4へ 導入して集塵処理を行う。第二の集塵機4で捕集された 粉塵の一部を消石灰粉と共に煙道7内の排ガス中に吹き 込み、消石灰分の循環吹き込みを行う。 (57) [Summary] [PROBLEMS] To increase the removal rate of acid gas, a large amount of slaked lime powder must be blown. In addition, the degree to which harmful organic chlorine compounds gradually decrease until exhaust gas is discharged is insufficient. SOLUTION: Exhaust gas discharged from a waste incinerator 1 is cooled to 120 ° C. to 200 ° C. in a temperature reducing tower 2, and the exhaust gas is introduced into a first dust collector 3 to remove a dust. Next, in the flue 7, slaked lime powder is blown into the exhaust gas, The exhaust gas into which the slaked lime powder has been blown is introduced into the second dust collector 4 to perform dust collection processing. Part of the dust collected by the second dust collector 4 is blown into the exhaust gas in the flue 7 together with slaked lime powder, and circulated blowing of slaked lime is performed.
