用于系統的船用樣氣干燥管部件

 博純用于制造醫療設備和呼吸氣體分析的產品

博純公司是通過ISO 13485 認證的醫療設備制造商，供應*的樣氣采樣管線、氣體干燥器和水分交換器，這些產品廣泛應用在麻醉監護、壓力測試/肺功能檢查、碳酸波形圖（二氧化碳監控）和哮喘監控（一氧化氮）上。我們的產品技術主要應用在去除呼吸樣氣中的濕氣，以方便精確分析呼吸氣體。

博純PD™系列氣體干燥管是一款含多根Nafion管的干燥管，設計用于高流量，高性能的氣體干燥應用。此款干燥管可以干燥至露點-45℃且不會去除其他化合物。PD系列干燥管應用包含用于連續煙氣排放和過程監測中的樣氣預處理。在這些應用中，樣氣在流經Nafion管束后被干燥，但不會帶走任何分析物。PD系列干燥管在燃料電池應用中可被用作加濕交換管。后，PD系列氣體干燥管也可用在小規模過程應用中。過程應用利用Nafion一個或多個*性能：高效，選擇性水分交換，離子交換能力和*的抗腐蝕能力。

產品特性:

• 流速達 40 l/m

• 使用溫度高達120° C

• 使用壓力達45 psi (值)

• 提供直線或卷曲結構

• 耐腐蝕

• 標準露點達 – 25° C, 可能達到更低值 (請工廠)

• 無分析物損失

• 沒有活動部件

工作原理:

PD系列干燥管由一個外置管殼內含一束0.030″外徑的Nafion管組成。氣體流入Nafion管，同時管式的膜壁吸收了水氣然后移除。通過管壁滲透的水氣被外管殼內反向流動的吹掃氣帶走。吹掃氣應為儀表風（-40℃露點）或是高于采樣氣流流量2到3倍的氮氣。

智能產品編號系統:

博純提供的PD系列干燥管包含三種尺寸的Nafion^®管束，并有多種長度及接頭類型可供選擇。根據您流速和干燥要求來選擇尺寸。按照選型指南和下列產品型號表來構建您合適的PD干燥管。

*樣氣流速：
2-10 lpm: PD-050T 系列
4-20 lpm: PD-100T 系列
10-40 lpm: PD-200T 系列

PD系列干燥管性能曲線:

這些性能曲線是根據入口20℃樣氣露點。對于那些高于環境溫度的情況，我們假設一半的干燥管將把露點降至環境溫度。因此，讀取下一段干燥管的值。例如：初始為50℃露點的氣流，2 slpm流量，PD-50T－24的干燥管可以產出6℃露點的氣體，12英寸的性能。訪問吹掃氣體配置頁面來學習更多博純客戶在他們設備中配置的吹掃方式。

計算PD系列壓降:

PD-50T;

ΔP (psid) = 0.0056 * 流速(splm) * 干燥管長度 (英寸)

PD-100T;

ΔP (psid) = 0.0028 * 流速 (splm) * 干燥管長度 (英寸)

PD-200T;

ΔP (psid) = 0.0014 * 流速 (splm) * 干燥管長度 (英寸)

PD 系列尺寸規格:

Perma Pure PD-Series™ gas dryers are multi-tube Nafion™ gas sample dryers designed for high flow, high performance gas drying applications. These dryers can be used to dry to -45°C without removing other compounds. Applications for PD-Series gas dryers include gas sample conditioning for continuous emissions and process monitoring. In these applications, sample gases flowing through the Nafion™ tubing are dried without removing any of the sample analytes. PD-Series dryers are also used as moisture exchangers in fuel cell applications. Fuel cell exhaust gases transfer their moisture and heat to the dry inlet gases (primarily hydrogen). Finally, PD-Series gas driers can be used in small scale process applications. Process applications take advantage of one or more of the unique properties of Nafion™: highly efficient and selective moisture exchange, ion exchange capabilities, and extreme corrosion resistance.

Product Features:

• Flow rates up to 40 l/m

• Operating temperatures to max. 120° C

• Operating pressures to 45 psi (absolute)

• Straight or coiled configuration

• Corrosion resistant

• Standard dew points to – 25° C, with lower values possible (contact factory)

• No loss of analytes

• No moving parts

Principle of Operation

PD-Series dryers consists of a bundle of 0.030″ O.D. Nafion™ tubes housed within a single large tube shell. Feed gas flows within the Nafion™ tubes while water vapor absorbs into the tubular membrane walls and is removed. Moisture permeating the tubing is carried away by a dry purge gas within the shell that flows counter-current to the feed. Purge gas should be instrument quality air (-40°C dew point) or nitrogen flowing at two to three times the sample flow rate.

nligent Product Numbering System

Perma Pure offers the PD-Series dryer with three sizes of Nafion™ tubing and in a variety of lengths and connection types. Choose the size based on your flow rate and dryness requirement and build your PD dryer according to the selection guide and the part number table below:

Recommended Sample Gas Flow Rates:
2-10 lpm: PD-050T Series
4-20 lpm: PD-100T Series
10-40 lpm: PD-200T Series

Select Your Dryer by Flow and Target Dew Point (Moisture Level)

PD Gas Sample Dryer Performance Curves

The Performance curves above are based upon an inlet dew point of 20°C. For conditions higher than ambient temperature, it is assumed that the first half of the dryer will be used to bring the dew point down to ambient. For this reason, read the value of the next shorter dryer. For example, a stream with an initial dew point of 50°C, flowing at 2 slpm; a PD-50T-24 should yield an outlet dew point of -6°C, the performance of the 12″ unit.

Calculating PD Series Pressure Drop

PD-50T;

ΔP (psid) = 0.0056 * Flow rate (splm) * Length of dryer (inches)

PD-100T;

ΔP (psid) = 0.0028 * Flow rate (splm) * Length of dryer (inches)

PD-200T;

ΔP (psid) = 0.0014 * Flow rate (splm) * Length of dryer (inches)
