Description
Technical field
The present invention relates to a kind of reactor, relate in particular to a kind of reactor of making biofuel.
Background technology
Biofuel is to utilize all kinds of animal-plant oil to be raw material, and with low-carbon alcohol process lactide reaction modifyings such as methyl alcohol or ethanol, it is finally become can be for a kind of fuel---the fatty acid methyl ester or the ethyl ester of oil engine use.Biofuel has good environmental-protecting performance; sulphur content is low; the discharging of sulfurous gas and sulfide reduces about 30% than ordinary diesel oil; oxygen level can reach 11%; ignition characteristic is good, thus the nuisances such as HC, CO that when burning discharges significantly reduce than ordinary diesel oil because its discharging does not contain nuisances such as sulfurous gas, lead, halogen; be very beneficial for environment protection, and compliance with environmental protection requirements.Therefore biofuel is the eco-friendly power source of present a kind of novel green.
Biofuel mainly adopts chemical method production, promptly use animal and plant grease and methyl alcohol or ethanol, under acidity or basic catalyst and high temperature transesterification reaction taking place, generate corresponding fatty acid methyl ester or ethyl ester, obtains biofuel through technologies such as washing, dryings again.And the equipment of production biofuel mostly adopts the reactor that has chuck, material inlet, catalyst inlet and solvent inlet all are arranged on the middle and upper part of kettle, have only discharge port to be positioned at the bottom of kettle, interior each material to reactor of chuck that high-temperature steam feeds kettle heats the realization esterification.But in esterification reaction process, employed its boiling point of low-carbon alcohol solvent is lower, as the boiling point of methyl alcohol at 64.7 ℃, the alcoholic acid boiling point is at 78.3 ℃, and the grease in the reactor is under the effect of steam and catalyzer, 120 ℃～250 ℃ of its temperature of reaction, therefore after methyl alcohol or ethanol intermittently enter reactor from kettle top, methyl alcohol or ethanol liquid surface can be vaporized state at once, though can mix material and solvent by whipping appts, methyl alcohol or alcoholic acid vapour mostly accumulate in the top in the still, are difficult to closely contact with the intravital grease of still, make to can not get the most effective combination between the material, cause esterification insufficient.For improving transesterification reaction, adopt the consumption that increases methyl alcohol or ethanol raw material usually and prolong the reaction times etc., but various materials are fully reacted, so the yield of diesel oil is not high, usually about 80% at present.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, esterification is made the reactor of biofuel fully.
The present invention is that the technical scheme that achieves the above object is: a kind of reactor of making biofuel, comprise kettle and the whipping appts that is installed on the kettle, described kettle is the jacket type structure with interlayer, steam inlet on the kettle and condensation-water drain communicate with interlayer, the material inlet that is respectively equipped with on the kettle, discharge port, catalyst inlet and solvent inlet communicate with the kettle reaction chamber, it is characterized in that: described material inlet and catalyst inlet are separately positioned on the top of kettle, discharge port is arranged on the bottom of kettle, and solvent inlet is arranged on the bottom of kettle.
The present invention is arranged on the bottom of kettle or/and the bottom with solvent inlet, when methyl alcohol or ethanol equal solvent from solvent inlet from autoclave body bottom or/and bottom when entering the reaction chamber of kettle, volatilization immediately behind the solvent contact high temperature, because methyl alcohol or alcoholic acid boiling point and the intravital temperature of still differ bigger, therefore methyl alcohol or ethanol can be upwards volatilization of spurting at its opening for feed place, can gasify rapidly in the very short time, and prolongation methyl alcohol or alcoholic acid reaction stroke, therefore can at utmost fully contact, the reinforced continuous charging that changes at the intermittence of solvent with grease.Because its alcoholysis of grease and esterification in the reactor are more abundant, so the yield of biofuel can reach more than 96%.Moreover, the present invention with methyl alcohol or ethanol from autoclave body bottom or/and the bottom adds in the still, the utilization ratio of solvent increases substantially, and reduces the solvent recuperation process.The present invention only changes the solvent inlet position of kettle, owing to need not to change other structure of kettle, kettle structure is simple, and facility investment is few, and the production efficiency height can satisfy commercial scale production.
