STRUCTURE AND PRINCIPLE OF DE-HUMIDIFICATION
Injection & expansion
As the compressed air gets into the generator (nozzle) and turns
horizontally at a high speed while expanding, the density and
pressure of the eddy current on the outside go up in the V-shaped
cylinder and the temperature on the outside goes up (increase
of temperature at stagnation point) while the temperature at
the center goes down. The top part becomes hot and a small quantity
of hot air is separated from the other part of the air to go
out through the hole (7. in the drawing).
The compressed air turns horizontally at a high speed in the
V-shaped cylinder with the nozzle mentioned in 1. right.
As the low-temperature and highly moist air in the central part
gets into the nozzle (3.in the drawing) while being compressed
and expands rapidly, the air temperature further drops and the
water content condenses instantly because of changes of its volume,
density and pressure.
The water content in saturated state is further cooled to turn
into water drops as it hits against the tube wall and the aluminium
plate (4. in the drawing) at a high speed.
The air gets into the generator (nozzle) again and turns horizontally
at a high speed.
Water drops and impurities are pushed away toward the wall and
the lower baffle plate (6. in the drawing) to be separated
from the air and get into the pot.
Air bleeding at the center
Only clean air passes toward the outlet through the cylinder
because the rotating force of the air does not drop up to immediately
under the cylinder (7. in the drawing).
Immediately before the outlet, the clean air is heated by the
dry air exhausted from the hole (8. in the drawing) and
is discharged to the outlet in the state of high-enthalpy air
of good quality.
