4.2 产品性能介绍
Sulzer BDHTM Floating Valve Tray
苏尔寿公司 BDHTM浮阀塔盘

Advantages:

The unique rectangular-shaped valves set the BDHTM tray apart from conventional valve trays. The valve is oriented parallel to the liquid flow direction, providing lateral vapor release and a closed upstream edge to minimize weeping. This contributes to an improved efficiency and capacity pro to conventional round valve trays. Further advantages of the rectangular valve are:

· Improved liquid flow due to lateral vapor release;
· Improved turndown ratio compared to round valves;
· The wide legs and lack of valve rotation reduce damage and wear;
· Available range of valve lifts and weight allow for optimal design;
· The design allows for top side valve replacement.

优点：

独特矩形阀设计使BDHTM浮阀塔盘不同于传统浮阀塔盘。其阀与液流方向平行，使液流无障碍地通过塔板，并降低液漏。经与传统圆形阀比较，它不仅可以提高分离效率且增加处理能力。其更多优点如下：

· 由于汽液向两侧释放，使液流无障碍地通过塔板；
· 与传统圆形阀比较，提高了操作弹性；
· 宽浮阀支脚和阀位方向固定，减少了安装和操作中损坏；
· 各种尺寸阀高和浮阀重量为工业生产提供了优化设计；
· 阀设计可从顶部进行更换，更为方便。

Sulzer I-RingTM New Generation Random Packing
苏尔寿公司 I-RingTM 新一代散堆填料

Advantages:

· I-Rings provide over 30% lower pressure drop than Pall® Ring.
· Revolutionary design enhances greater capacity and efficiency than other random packing;
· Geometric design minimizes liquid hold-up;
· Direct replacement of the widely used IMTP®;
· Simple installation and removal.

优点：

· I-Rings压降比Pall® Ring降低30%；
· 优化设计比其它散堆填料处理能力和效率都有很大提高；
· 优化几何设计减小了持液量；
· 直接替代广泛应用IMTP®散堆填料；
· 安装和卸料更简便。

Sulzer KnitMesh VKR™ Mist Eliminator
苏尔寿公司VKR™ 丝网式除沫器

Advantages:

Sulzer KnitMesh mist eliminators have an excellent track record as a low cost, highly versatile and efficient method of removing liquid entrainment from gas streams. They are produced as a bed of knitted mesh which presents a tortuous path and large surface area to the droplets entrained in the gas stream. Separation is achieved by impingement on, and capture by, the filaments of the mesh where the droplets coalesce and drain.

The Sulzer KnitMesh VKR™ Mist Eliminators provide high performance wherever liquid entrainment must be removed from a vertically flowing gas stream. The strategically placed collecting channels provide higher operational gas and liquid flow capacity.

优点：

苏尔寿KnitMesh除沫器性能优越，其成本低，是分离气流中液体夹带通用有效方法。该除沫器作为丝网床，对夹带在气流中液滴来说，丝网具备曲折路径和较大比表面积。气流冲击丝网，并被丝网拦截，液沫在拦截地方聚结，最终形成液滴而排液，实现了气液分离。

苏尔寿公司VKR™ 型丝网除沫器能够提供极高除沫效率。特殊布置液体收集槽有效避免了被捕集液滴二次夹带，可以有效地增加丝网除沫器处理能力。
