Secondary steam allows constituent part therein to form trapped fluid by reflection gear liquid cone；Described sedimentation liquid, trapped fluid are respectively formed whereabouts
Drop.
Main component in steam is to carry the methyl alcohol of a small amount of glycerin component secretly, and sedimentation liquid is then to have carried a small amount of first secretly
The glycerine of alkoxide component.One time steam runs into reflection gear liquid cone in rising, and glycerin component therein can be retained down and become liquid
State trapped fluid, greatly reduces the glycerol content in a steam, and sedimentation liquid and trapped fluid can fall under gravity.
2）By step 1）A middle steam by reflection gear liquid cone imports cyclone hydraulic separators and is separated, and obtains gas phase
The phegma of secondary steam and liquid phase；Secondary steam is discharged to methanol recovery device again, phegma is back to dealcoholysis tower；Make
Phegma forms drop and is contacted with the steam for rising, and forms backflow drop；
Secondary steam is the methyl alcohol of purity >=99.5%, and phegma is then the glycerine for having carried Trace Methanol secretly.Phegma with
The form of drop is contacted with a steam, and mass-and heat-transfer effect occurs, i.e., phegma makes a small amount of glycerine steam in steam liquefy,
The backflow drop of whereabouts is formed together with phegma, and the heat of phegma rises methyl alcohol vaporizing.
3）By step 1）In dripping drops and step 2）In phegma drop in dealcoholysis tower bottom and accumulate sedimentation liquid,
And discharge it.
As one kind preferred embodiment, it is further comprising the steps of：
4）The sedimentation liquid of discharge is pumped into reboiler, is allowed to be formed 140 DEG C of circulation steam and circulation fluid, and be transported to
The top of dealcoholysis tower, the lower section of spiral nozzle；In making the structured packing that the circulation steam of upward motion enters in dealcoholysis tower, and with
Enter backflow drop therein and dripping drops contact from structured packing top；Circulation fluid then moves downwardly into sedimentation liquid.
Sedimentation liquid is the glycerine for being entrained with a small amount of methyl alcohol component, by drop temperature control in reboiler at 140 DEG C or so, far
Less than temperature, the boiling point higher than methyl alcohol that glycerol polymerization is decomposed.By the heating of reboiler, methyl alcohol composition therein is set to be changed into following
Ring steam, glycerin component then occur in the form of the circulation fluid of liquid.Circulation steam is with the liquid for falling respectively from upper and lower entrance
There is mass-and heat-transfer effect in structured packing, the methyl alcohol component in the two forms steam rising, glycerin component in the presence of heat
Drop is formed to fall.Circulation fluid then enters in sedimentation liquid.
5）Repeat step 1）-4）, circulate said process and occur, the component of in time inspection sedimentation liquid, when its methyl alcohol
During content≤0.5%, glycerine retracting device is derived.
Methanol content >=99.5% that the present invention is separated, fully meets the requirement of production of biodiesel methanol content；And
Steam, electric equal energy source consumption only have the 2/5 of rectifying column；The glycerine separated is by assay detection, wherein methanol content
It is that the treatment of glycerine next step is laid a good foundation below 0.5%.
The present invention has carried out three-level and has separated based on methyl alcohol with the temperature difference of the boiling point of glycerine：The first order be spiral nozzle out
Glycerine-methyl alcohol mixed liquor a large amount of methyl alcohol vaporizings, glycerine is liquefied because boiling point is different；The second level is that cyclone hydraulic separators will be big
Phegma with glycerine as key component out, then by liquid distribution trough is again introduced into dealcoholysis tower and is allowed to by amount separating methanol
Generation mass-and heat-transfer is contacted with a steam to act on；The third level be then allow circulation steam with whereabouts liquid respectively from it is upper and lower enter
Enter structured packing and mass-and heat-transfer effect occurs.
The above embodiment of the present invention is only example to illustrate the invention, and is not to implementation of the invention
The restriction of mode.For those of ordinary skill in the field, other can also be made not on the basis of the above description
With the change and variation of form.Here all of implementation method cannot be exhaustive.It is every to belong to technical scheme
The obvious change amplified out changes row still in protection scope of the present invention.
