Low level mounted and energy conserving with
effective scrubbing of outlet gases. This offers the
advantage over other systems in producing vacuum and
simultaneously scrubbing entrained gases before
discharging to the atmosphere, making Steam
jet-liquid jet ejector combination systems an ideal
selection for contaminated and/or corrosive
applications.
They are available in multi-element form as a
central vacuum source on multi-purpose process
applications.
Steam jet-liquid jet ejectors are generally used to
create vacuum upto 759 mm of Hg in medium size
process vessels. They are simple in construction,
operation and maintenance. The system is more
suitable where low capital investment is preferred.
It is usually used for batch plant applications
requiring coarse vacuum and low level installations.
With the liquid recirculating pump being the only
moving part the Liquid jet ejector system is simple
to maintain and very reliable to operate. The liquid
jet alone can pull vacuum upto 710 mm of Hg by using
water at ambient temperature, as motive medium.
Steam jet-liquid jet combination can further enhance
the vacuum upto 759 mm of Hg depending upon the
number of stages of steam ejectors, backed up liquid
jet ejectors. chem combination systems incorporate
single or two stage steam ejectors with liquid jet
ejector.
