工作原理:

PD系列干燥管由一個(gè)外置管殼內(nèi)含一束0.030″外徑的Nafion管組成。氣體流入Nafion管，同時(shí)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(nèi)反向流動(dòng)的吹掃氣帶走。吹掃氣應(yīng)為儀表風(fēng)（-40℃露點(diǎn)）或是高于采樣氣流流量2到3倍的氮?dú)狻?/p>

PD 系列尺寸規(guī)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)
