Use: 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 bio-diesel special separator is designed and manufactured by the long termpractical research and study on the basis of adopting international advanced bio-dieselseparation technology, it is the improved model on the basis of DRY 530 disc separatorand it adopts some key technology and necessary improvements according tothe features and characters of bio-diesel separation, separation is more effectiveand satisfactory. And it is the sole special separation equipment for bio-dieselproduction.Technical procedure:Rap oil and methanol produce continuous methyl esterification at the condition ofexisting of sodium hydroxide activator, which comes into water washing technicsafter two step methyl esterification. The first step reaction is ongoing when methanol and activator are put into heatedrap oil, and the fatty acid is methyl esterified partially. Rap oil is almostmethyl esterified in this step, the generated mixtures of glycerin and methanolare brought out continuously. To separate stuff which is methyl esterfied partiallywith separator, and to obtain the mixtures of rap oil/ methyl esterification.The methanol and glycerin will be reclaimed at the next technics. Stuff is esterifiedfurther at the second step, which comes into methanol and activator. To separatethe reactive two phases.Remainder methanol in rap oil methyl esterification could be used in the technicsby evaporation. Water washing is divided into twice, the first one adopts waterwashing, 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 relatedto reaction temperature and pressure and activator. This technics is also suitablefor methyl esterification of other propagation oil. Because the reaction isdivided to two steps, generated glycerin each step will be centrifugal separated,the reaction degree of methyl esterification could be over 99%. The purity ofgenerated RME is comparable with distilled fatty acid. Principle:The bowl driven by the motor through the friction clutch spiral gear pair rotatesaround the main shaft at a high speed. Stock liquid flows into the bottom of bowl'swall through the bottom edge of disc seats and their holes in it. Solid materialsettles onto the inner surface wall of the bowl and forms into the residueby the centrifugal force field. Then the residue will be discharged manually afterthe machine stops. Light liquid flows along up the outer cone surfaces of discsto the main shaft center, passes through the light liquid centripetal pump anddrains out of the light liquid outlet. Heavy liquid flows along the inner taperedsurface of disc down to the bowl's wall and then passes through the heavy liquidcentripetal pump and drains out the heavy liquid outlet. producing area:China payment:T/T, L/C
