6.1.3 Cleaning of Honeycomb
Honeycomb Rotor cleaning steps:
1) Use a vacuum-cleaner with brush to suck up the dust on rotor surface.
2) Blow off the dust in the rotor channels with compressed air.
3) If there is dirt sticking to the channel walls inside the rotor, cleaning steps
are as follows:
a. Saturate the rotor by blowing humid air (higher than 60%RH) through the
rotor without having regeneration circuit on. This can be done by just
turning the regeneration heater off and still have the process blower
running if process air has high humidity. If the process air is too dry try to
put a humidifier in the air stream. Do this for one hour.
b. According to the character of the dirt, sink the rotor into water with cleaning
agent in it (PH value 3~2 liquid is applied to silica gel, PH value 7~10
applied to molecular valve). Greasy dirt should be put into a detergent
solution with xylene. 15 minutes cleaning is suggested.
c. Take the rotor out of the liquid and let it rest with the channels vertically for
5 minutes so the liquid can run out.
d. Blow off the residual liquid in the channels with compressed air.
e. Put the rotor back into the dehumidifier and run the unit with regeneration
circuit (the regeneration temperature between 50 and 60 ) on for at
℃ ℃
least one hour.
Note!
1. Note that in the dry air and wet air outlets, there will be high
concentrations liquid out for some time. If a solvent has been used,
there will be a residual smell for several days.
2. For some dirt which is greasy and sticky in the rotor, 100% elimination
is impossible. The only one thing you can do is to replace the rotor for
the cleaned rotor performance can only be recovered partly.
Note
！
Please note that some dirt, like oil mist or other types of sticky mist, is
almost impossible to clean out effectively so the rotor may not be cleaned
