1-6 Description

Brooks Instrument DLI (Direct Liquid Injection) vaporizer is a fully
integrated direct liquid injection system offered in three different models
depending upon process conditions and user preference.
DLI Flange (DLIFS)
The DLIFS vaporizer (see Figure 1-1) is an integrated system which
combines Brooks Instrument's proprietary atomizer along with a flange,
segmented 316L SS recirculating heat exchanger that is wrapped in band
heaters and insulation inside an aluminum enclosure and mounted on an
aluminum back plate.
Brooks' proprietary atomizer exponentially multiplies the specific surface
area of an inlet fluid by creating millions of 2-5 micron size droplets through
the use of a supersonic shock front caused by the rapid expansion of a
carrier gas through an orifice. Increasing the fluid's surface area improves
the heat transfer efficiency. The 316L stainless steel atomizer, with
removable orifice, is a fully-serviceable, interchangeable component sized
for the desired fluid and mass flow rate.
The heat exchanger, with its highly effective heat transfer design, quickly
and efficiently vaporizes the mixture of micron diameter droplets and
carrier gas. The consistent control of both temperature and pressure
conditions inside of the heat exchanger ensures that incoming liquid
droplets are not only efficiently vaporized but remain in a vapor state and
don't recondense. The heat exchanger assembly is a fully-serviceable
assembly comprised of four 316L SS flange segments are bolted together
with twelve fasteners utilizing either elastomeric or metal seals.
• Wetted Materials: 316L SS with either Nickel 200, or Kalrez seals
• Dual K-type thermocouples: one for operating temperature and one for
over-temp limit
• Removable atomizer & exit orifice(s) are sized to the desired operating
conditions
• Resistive band heater(s) 200-2500 Watts
• Insulation jacket
• Powder-coated aluminum cover
• Variety of process connections: tube stub; tube compression; face seal
(1/8" to ½")
