Description

第３管７２は、図２及び図３に示すように、第２管７０の内側に延在し、上端部で間隙７２ａを有して処理流体流出管５４の下端開口部５４ａを挿入させたＩｒ製の管体である。
また、第３管７２は、上部で上記間隙７２ａを介して管体内に連通し、下部で中和急冷器６４外と連通する第２環状部８４を第２管７０との間に形成している。第２環状部８４は、第１管６８の下端フランジ６８ａと盲フランジ７８とをリング結合するリングガスケット７６によって生じる隙間７６ａを経て、盲フランジ７８を貫通する貫通孔７８ａにより中和急冷器６４外と連通している。
Ｉｒは、機械加工性が乏しいため、第３管７２の下端部は、図３に示すように、インコネル６２５製のスリーブ８６にネジ結合され、スリーブ８６は盲フランジ７８にネジ結合で結合されている。 The third pipe 72, as shown in FIGS. 2 and 3, extends inside the second pipe 70 and has a gap 72a at the upper end, into which the lower end opening 54a of the processing fluid outflow pipe 54 is inserted. It is a tube made of Ir.
Further, the third pipe 72 communicates with the inside of the pipe at the upper portion through the gap 72a , and a second annular portion 84 communicating with the outside of the neutralization quencher 64 at the lower portion is formed between the third pipe 72 and the second pipe 70. There is. The second annular portion 84 passes through the gap 76a created by the ring gasket 76 which ring-connects the lower end flange 68a of the first pipe 68 and the blind flange 78, and the outside of the neutralization quencher 64 by the through hole 78a passing through the blind flange 78. It is in communication with
Since Ir has poor machinability, the lower end of the third tube 72 is screwed to the sleeve 86 made of Inconel 625 as shown in FIG. 3, and the sleeve 86 is screwed to the blind flange 78 There is.
