Using the Diffusion Dryer
This section gives a description of the major components of the
Diffusion Dryer.
Inlet and Outlet Connectors
The inlet and outlet connectors are ½ in. female Swagelok
®
fittings
that connect to ½ in. OD tubing.
Water Trap and Drain Valve
The inlet of the Diffusion Dryer contains a trap to collect large
water droplets before they enter the desiccant. The trap is equipped
with a drain valve to allow easy removal of trapped water.
Desiccant Dryer
The Model 3062 Diffusion Dryer is a general-purpose aerosol dryer
consisting of two concentric cylinders (see Figure 2). The inner
cylinder is made of wire screen and the outer cylinder is made of
Plexiglas. The annular space between the two cylinders is filled with
silica gel. The aerosol enters the dryer at the end equipped with the
water trap and exits at the opposite end.
The silica gel in the annular space maintains a dry atmosphere
within the inner tube. Passing the aerosol through this tube dries
the aerosol particles without substantial particle loss.
