Biodiesel Machine The manufacturing process of biology derv
(1) physics is pithy: Handle grease to hydrate or phosphoric acid above all, get rid of the phosphatide of meantime, colloid wait for material. Again grease warm-up, dehydrate, take off gas to enter de-acidification tower, maintain residual voltage, connect excessive vapour, below vapour temperature, free acid and vapour together evaporate goes out, via condensation cent goes out, get rid of beyond free fatty acid lose completely, the free acid in grease can fall extremely small amount, pigment also can be split up, make colour becomes shallow. All sorts of abandoning move vegetable oil to be below the DYD activator effect of free-standing development, choose ester to change, alcoholysis together resonant technology generates ester of crude fat acerbity armour.
(2) methanol beforehand ester changes: Above all come unglued of grease to hydrate, get rid of with centrifugal the garrulous form content that forms when the to hydrate such as phosphatide and glue, next grease dehydrate. Material oil attends excessive methanol, I am put in acidity activator, undertake beforehand ester is changed, make free acid change becomes armour ester. Evaporate gives methanol water, after classics is fractional, without free acerbity cent gives ester of armour of oleic acid of ester of armour of C12-16 palmy acid and C18.
(3) ester exchanges echo: The grease of classics pretreatment and methanol together, attend a few NaOH to do activator, in sure temperature and often press next undertaking that ester exchanges echo, can generate armour ester namely, choose 2 paces echo, the take leave of that passes a special program implement successional ground gets rid of first the glycerine that generates in echo, make ester exchanges resonant proceed.
(4) gravitational deposit, bath and statified.
(The taking of the take leave of of 5) glycerine and rough-wrought armour ester.
(Of the emergence of 6) water portion, methanol commentate piece, the taking of the emergence of activator and purificatory biology derv.
All technology flow finishs closed circuit loop, material all is used integratedly, finish clean production. Depict as follows roughly: Material pretreatment (dehydration, deodorization, purify)——Resonant boiler (add alcohol + activator + 70 ¡æ )——Blend echo 1 hour——-Platoon of deposit take leave of is miscellaneous——-Call in mellow——Filter——–Goods
