The
invention
- The
problem to be solved:
The main aim was to eliminate the
deficiencies and unfavourable properties
(in the course of time the liquid film
becomes interrupted, shrinked over the
supporting surface, the liquid begins to
flow, due to the dirty and greasy
surface) of the liquid films developed
over a supporting surface that are used
in the usual liquid film heat-exchangers
and mixing condensers.
|
- Definition:
The object of the invention is a
tensioned liquid film heat-exchanger,
without supporting surface, where both
sides of the liquid film are in contact
with the gaseous agents. The liquid film
develops between two nearly vertical
tensioning wires that are slightly
inclined towards each other at their
lower ends and, their length, inclination
angle and distance related to each other,
depend on the properties (surface-tension
constant) of the liquid.
|
- Presentation:
In the invented arrangement the
liquid that overflows on the horizontal
edge of the storage tank practically
falls freely between two tensioning wires
(rods), that are nearly vertical and
slightly inclined towards each other, a
coherent, stable liquid film develops
during the free fall. The dimensions
(film thickness, width) of the liquid
film are constant in the course of time
and, its coefficients of heat and/or mass
transfer are excellent due to the
turbulent flows developed in it.
Practically, an unlimited number of
liquid films can be applied connecting
them one after the other in series or
side by side in parallel. Before the
liquid film would be interrupted its
lower end is immersed into and below the
liquid level of the collecting recipient,
this way, its operation is noiseless. The
automatic development of the liquid film
between the two tensioning wires is
provided by the self-development system,
this way, higher air velocities can also
be used.
|
- Application:
The invented arrangement can
advantageously be used in air
conditioners, mixing heat-exchangers,
cooling towers, water and waste-water
treatment (oxygenation) plants, chemical
industry processes, evaporators, natural
water aerators, gas washers,
paint-sprayer rooms.
|
- Advantages:
Energy saving, noiseless operation,
simple, calculable, low investment costs.
|
- Stage
of development:
A demonstration model and the measurement
results are available.

- Documentation
available: Yes
