【考案の詳細な説明】
本考案はボイラに使用される復水器に関するものである
。[Detailed Description of the Invention] The present invention relates to a condenser used in a boiler.
ボイラの復水器から不凝縮気体を抽出するために、復水
器には冷却管支持板との間に最終空気冷却部が設けられ
る。In order to extract non-condensable gases from the boiler condenser, the condenser is provided with a final air cooling section between it and the cooling tube support plate.
第１図はこの最終空気冷却部の構造を示す断面図を示す
もので、冷却水入口側の冷却管支持板２には冷却管群中
央部の空気冷却部の長手方向に設けられて多数の通気孔
を有するパイプチャンネル３と、管支持板２と管板１と
の間に１つのじゃま板４とが支持されており、管板の外
側には器外に設けられた空気抽出器に通じる空気抽出管
５が前記管群中央部に対応して取付けられている。Fig. 1 shows a cross-sectional view showing the structure of this final air cooling section.A cooling tube support plate 2 on the cooling water inlet side has a large number of holes provided in the longitudinal direction of the air cooling section in the center of the cooling tube group. A pipe channel 3 having ventilation holes and a baffle plate 4 are supported between the tube support plate 2 and the tube sheet 1, and the outside of the tube sheet communicates with an air extractor provided outside the vessel. An air extraction tube 5 is attached corresponding to the central portion of the tube group.
不凝縮気体は前記パイプチャンネル３を通って流れ、じ
ゃま板４において方向を変えて後に空気抽出管５を経て
排出される。The non-condensable gas flows through said pipe channel 3, changes direction at the baffle plate 4 and is later discharged via the air extraction pipe 5.
しかしながらパイプチャンネル３から出た不凝縮気体は
完全な不凝縮気体ではなく未不凝縮気体であって、なお
少しの飽和蒸気を含んでいる。However, the non-condensable gas coming out of the pipe channel 3 is not completely non-condensable gas, but is non-condensable gas and still contains some saturated vapor.
このために不凝縮気体と共に蒸気も同時に排出されるの
で、空気冷却部に不凝縮気体がある程度停滞し、復水器
の性能低下、さらには冷却管の腐食を生じることが懸念
される。For this reason, steam is discharged together with the non-condensable gas, so there is a concern that the non-condensable gas will stagnate to some extent in the air cooling section, causing deterioration in the performance of the condenser and further corrosion of the cooling pipes.
本考案は上述の欠点を無くして性能の高い復水器を提供
することを目的としている。The present invention aims to eliminate the above-mentioned drawbacks and provide a condenser with high performance.
第２図は本考案による復水器の最終空気冷却部の構造を
示す断面図を示す。FIG. 2 is a sectional view showing the structure of the final air cooling part of the condenser according to the present invention.
この場合には管板１と管支持板との間に多重のじゃま板
４が設けられている。In this case, multiple baffle plates 4 are provided between the tube plate 1 and the tube support plate.
このように多重のじゃま板を設けることにより、パイプ
チャンネル３から空気抽出管５の入口までの間における
未不凝縮気体を再冷却する距離が長くなり、蒸気の混じ
った不凝縮気体は空気抽出管５の入口部で完全な不凝縮
気体となる。By providing multiple baffles in this way, the distance for recooling the uncondensed gas between the pipe channel 3 and the inlet of the air extraction pipe 5 becomes longer, and the uncondensed gas mixed with steam is removed from the air extraction pipe. It becomes a completely non-condensable gas at the inlet of No.5.
