Detailed Product Description

Usage:
Bio-diesel is a kind of clean fuel contains oxygen with good lubricating performance,
safe storage and transportation and usage, excellent explosion proof; which could be biologic resolved as rebirth source; nonpoisonous, safe burning. Bio-diesel could be obtained by the technics of ester exchange centrifugal separation of vegetable oil and animal oil and wasted oil etc raw material.

DRY600 Model bio-diesel special separator is designed and manufactured by the long term
practical research and study on the basis of adopting international advanced bio-diesel
separation technology, it is the improved model on the basis of DRY 530 disc separator
and it adopts some key technology and necessary improvements according to
the features and characters of bio-diesel separation, separation is more effective
and satisfactory. And it is the sole special separation equipment for bio-diesel
production.

Technical procedure:
Rap oil and methanol produce continuous methyl esterification at the condition of
existing of sodium hydroxide activator, which comes into water washing technics
after two step methyl esterification.

The first step reaction is ongoing when methanol and activator are put into heated
rap oil, and the fatty acid is methyl esterified partially. Rap oil is almost
methyl esterified in this step, the generated mixtures of glycerin and methanol
are brought out continuously. To separate stuff which is methyl esterfied partially
with separator, and to obtain the mixtures of rap oil/ methyl esterification.

The methanol and glycerin will be reclaimed at the next technics. Stuff is esterified
further at the second step, which comes into methanol and activator. To separate
the reactive two phases.

Remainder methanol in rap oil methyl esterification could be used in the technics
by evaporation. Water washing is divided into twice, the first one adopts water
washing, and the second one adopts acid water. To separate washing water with centrifuge.

Rap oil methyl esterification by water washing passes vacuum dryer and heat exchange cooling. Transesterification is equilibrium reaction. Equilibrium is related
to reaction temperature and pressure and activator. This technics is also suitable
for methyl esterification of other propagation oil. Because the reaction is
divided to two steps, generated glycerin each step will be centrifugal separated,
the reaction degree of methyl esterification could be over 99%. The purity of
generated RME is comparable with distilled fatty acid.

Principle:
The bowl driven by the motor through the friction clutch spiral gear pair rotates
around the main shaft at a high speed. Stock liquid flows into the bottom of bowl's
wall through the bottom edge of disc seats and their holes in it. Solid material
settles onto the inner surface wall of the bowl and forms into the residue
by the centrifugal force field. Then the residue will be discharged manually after
the machine stops. Light liquid flows along up the outer cone surfaces of discs
to the main shaft center, passes through the light liquid centripetal pump and
drains out of the light liquid outlet. Heavy liquid flows along the inner tapered
surface of disc down to the bowl's wall and then passes through the heavy liquid
centripetal pump and drains out the heavy liquid outlet.
