蒸発部上部の気水分離機能は図2に示される。蒸発室の下部で反転力と上部で

蒸発部上部の気水分離機能は図2に示される。蒸発室の下部で反転力と上部で遠心力を利用できる構造を持ち、コンパクトで分離効率が良いため従来広く使用されていた。一次スチームが入る加熱部は、ピュアスチームが直接接触する外筒内に設けているため、加熱部の胴板に長手方向溶接線や管板の差込み溶接線が存在する。この個所において溶接部の施工欠陥により度々問題が発生している。加熱部の胴部に腐食もしくは溶接による欠陥が出た場合、一次スチームとピュアスチームとの交差汚染が直ちに生じるリスクがある。対策として、図3や図4のように熱交換部を蒸発室外部に設ける設計により品質リスク低減を計っている機種もある。また、図2の場合は蒸発部胴板と仕切円筒の間の表面状態を点検出来ずGMP上好ましくない構造である。さらに、熱交換部（一次スチーム側）を蒸発室の内部に組み込む方式は蒸発缶の全長が長くなり、MWSの据付け高さが高くなることが難点である。

結果 (英語) 1:

Upper evaporator part care water separation ability is shown in Figure 2. Have a structure can use a centrifugal force in reverse and top in the bottom of the Chamber, compact and better separation efficiency for conventional were widely used. Contact pure steam enters the primary steam heating of the outside in the tube because of the longitudinal direction welded to the shell plate of the heater plug wire and tube sheet welding line exists. In this place by construction defects in welds often caused problems. The risk if came out due to corrosion or weld defects in the heating of the body of the primary steam and pure steam and cross-contamination occurs immediately. The design as shown in Figure 3 and Figure 4 heat exchanger placed evaporator with external clocking quality risk models. Also, could not check the evaporation of body Board and transfer cylinder between surface condition figure 2 If the GMP preferably on no structure. Method, heat-exchanger (primary steam side) into the Interior of the evaporation Chamber is longer overall length of the evaporator, in can be the installation height of the MWS.

結果 (英語) 2:

Steam-water separation function of evaporation upper portion is shown in Figure 2. Has a structure capable of utilizing centrifugal force in reversing force and the upper at the bottom of the evaporation chamber, for a good compact separation efficiency it has been conventionally used widely. heating part of the primary steam enters, since the pure steam is provided in the outer tube in direct contact, there is inserted the weld line of the longitudinal weld lines and the tube plate to the shell plate of the heating unit. Are often the problem is caused by construction defects in welds in this point. If the defects caused by corrosion or welded to the body portion of the heating section came out, cross-contamination of the primary steam and pure steam is immediately arise risk. As a countermeasure, there is also models that measure the quality risk reduced by design to provide a heat exchanger in the evaporation chamber externally as shown in Figure 3 and Figure 4. Also, a GMP undesirable structural can not check the surface condition between the evaporating section and the partition plate cylinder cylinder case of FIG. In addition, a method of incorporating a heat exchange unit (primary steam side) in the interior of the evaporation chamber the longer the total length of the evaporator, a disadvantage that the installation height of the MWS is high.

結果 (英語) 3:

The gas water separation function of the upper portion is shown in Fig. 2. To have a structure capable of using centrifugal force and the reverse force of the upper and the lower vaporizing chamber, which is widely used in the prior art for better separation efficiency. The primary steam heating portion, which is provided in the outer cylinder to directly contact the pure steam, socket welding line of the tube plate and the shell plate in the longitudinal direction of the welding line of the heating unit. In this area due to construction defects of weld zone is often the problem.When the defects due to corrosion or welding on the heating barrel, and the steam is generated immediately after the risk of cross contamination and pure steam. As a countermeasure, as shown in Fig. 4 and Fig. 3 is a measure of quality risk reduction on the heat exchange portion provided on the outside of the evaporation chamber by the model. In addition, in the case of Fig. 2 and the evaporation portion of the partition plate, the surface condition of the cylinder between the inspection could not be GMP on structure. In addition, theSteam heat exchange unit (primary) in the interior of the evaporation chamber into the system, the overall length of the evaporator is increased, and the rise of the installation height of the MWS.
