Title (EN) SMOKE EXHAUST DESULFURIZATION DEVICE

Abstract:
(EN) [Problem] To provide a smoke exhaust desulfurization device that, during smoke exhaust desulfurization by moving-bed dry-process desulfurization, can achieve a high rate of desulfurization in a limited installation area. [Solution] According to the present invention, in each of a first chamber that is a lower region of a desulfurization tower and a second chamber that is an upper region, through-ports through which smoke exhaust gas pass are formed in facing side walls, and a net is provided on the outside of the through-ports. A guide path is formed to guide smoke exhaust gas that has flowed out from the through-ports of the first chamber to the through-ports of the second chamber. A desulfurizing-agent downward flow that also acts, for example, as a desulfurizing agent is formed from an upper portion of the second chamber to a lower portion of the first chamber. Smoke exhaust gas is first made to contact a moving-bed-particle downward flow as a crossflow in the first chamber and is then made to contact the downward flow as a crossflow in the second chamber in the opposite direction of the flow of the smoke exhaust gas in the first chamber.
(FR) La présente invention vise à fournir un dispositif de désulfuration d'évacuation de fumée qui, pendant la désulfuration d'évacuation de fumée par désulfuration par voie sèche à lit mobile, peut atteindre un taux élevé de désulfuration dans une zone d'installation limitée. À cet effet, selon la présente invention, dans chacune d'une première chambre qui est une région inférieure d'une tour de désulfuration et d'une seconde chambre qui est une région supérieure, des orifices traversants, à travers lesquels un gaz d'évacuation de fumée passe, sont formés dans des parois latérales opposées, et un filet est situé sur l'extérieur des orifices traversants. Un trajet de guidage est formé pour guider le gaz d'évacuation de fumée, qui s'est écoulé hors des orifices traversants de la première chambre, vers les orifices traversants de la seconde chambre. Un flux descendant d'agent de désulfuration qui agit également, par exemple, comme agent de désulfuration est formé d'une partie supérieure de la seconde chambre à une partie inférieure de la première chambre. Le gaz d'évacuation de fumée est d'abord mis en contact avec un flux descendant de particules à lit mobile sous forme d'écoulement transversal dans la première chambre, puis est mis en contact avec le flux descendant sous forme d'écoulement transversal dans la seconde chambre dans la direction opposée de l'écoulement du gaz d'évacuation de fumée dans la première chambre.
(JA) 【課題】移動層乾式脱硫方式を用いた排煙脱硫を行うにあたって、設置面積を抑えながら、高い脱硫効率が得られる排煙脱硫装置を提供することにある。 【解決手段】脱硫塔の下部領域である第1室及び上部領域である第2室の各々において、互いに対向する側壁に、排煙ガスが通過するための通過口を形成し、通過口の外側にネットを設ける。また第1室の通過口から流出した排煙ガスを第2室の通過口に案内するための案内路を形成する。そして第2室の上部から第1室の下部に亘って、例えば脱硫剤を兼用する脱硫剤の下降流を形成し、排煙ガスを先ず第1室において移動層粒子の下降流に対して十字流状に接触させ、次いで第2室において第1室内の排煙ガスの流れの向きとは反対向きで下降流と十字流状に接触させる。
