Abstract
The utility model provides a device for extracting fatty amine from fatty amine distillation residue, which is provided with a film evaporator. A heat transfer oil inlet and a heat transfer oil outletare arranged on the side of the film evaporator. The upper part of the film evaporator is provided with a fatty amine residue inlet, and the bottom thereof is provided with a residue outlet. A distillation steam outlet is arranged at the top of the film evaporator, and is communicated with an inlet of a condenser. An outlet of the condenser is communicated with an inlet of a distillation liquor receiver. A distillation liquor outlet is arranged at the bottom of the distillation liquor receiver. A vacuum pipe is arranged at the tops of the condenser and the distillation liquor receiver. The condenser is also connected with a cooling water inlet and a cooling water outlet. A residue outlet pipe valve is arranged at the bottom of the film evaporator. The device for extracting the fatty amineadopts the film evaporator to extract the fatty amine from the fatty amine residue, the residence time of materials in the extraction process is shortened, the volatile components of the materials are quickly gasified, the quality of the distillation product is enhanced, the energy consumption is decreased, the yield of the fatty amine is enhanced, and each quality index respectively meets the requirements of standards.
Description
Technical field
The utility model provides the device in a kind of aliphatic amide production.
Background technology
What at present, the distillation of the residue of aliphatic amide was adopted is batch still formula water distilling apparatus.During use, because material viscosity is bigger, heat-transfer effect is relatively poor, causes material longer in the following residence time of the condition of high temperature.Because aliphatic amide belongs to heat-sensitive substance, very easily polymerization and decomposition when being in the condition of high temperature for a long time causes the distillage yield low, and product purity and color are relatively poor, and quality product is low, need carry out second distillation.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of device that extracts aliphatic amide from the aliphatic amide distillation residue, to improve the yield of aliphatic amide.
The utility model is to realize like this, a kind of device that from the aliphatic amide distillation residue, extracts aliphatic amide, it has thin-film evaporator, the side of thin-film evaporator is equipped with heat conductive oil inlet, the thermal oil outlet, aliphatic amide residue material inlet is arranged at thin-film evaporator top, the residue outlet is arranged at the bottom, the thin-film evaporator top also has the distillation steam outlet pipe to be connected with the import of condenser, the outlet of condenser is connected with the import of distillate receiver, the distillate outlet is arranged at the bottom of distillate receiver, vacuum-pumping tube is arranged at condenser and distillate receiver top, also be connected with entrance of cooling water and cooling water outlet on condenser, the bottom of thin-film evaporator has residue to go out pipe valve.
The device of this extraction aliphatic amide, adopt thin-film evaporator from the aliphatic amide residue, to extract the aliphatic amide product, shortened the residence time of material in leaching process, the volatile components of material gasifies rapidly, improve the quality of distillage, reduced energy consumption, improved the yield of aliphatic amide, the good product quality that reclaims, the equal conformance with standard requirement of every quality index.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model structure.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model and principle of work.
As shown in drawings, a kind of device that from the aliphatic amide distillation residue, extracts aliphatic amide of the utility model, it has thin-film evaporator 1, the side of thin-film evaporator is equipped with heat conductive oil inlet 8, thermal oil outlet 9, aliphatic amide residue material inlet 4 is arranged at thin-film evaporator top, residue outlet 7 is arranged at the bottom, the thin-film evaporator top also has distillation steam outlet pipe 5 to be connected with the import of condenser 2, the outlet of condenser is connected with the import of distillate receiver 3, distillate outlet 6 is arranged at the bottom of distillate receiver, vacuum-pumping tube 12 is arranged at condenser and distillate receiver top, also be connected with entrance of cooling water 10 and cooling water outlet 11 on condenser, the bottom of thin-film evaporator has residue to go out pipe valve 7.
Thin-film evaporator adopts wiped film evaporator, and its concrete structure and principle of work are prior art, no longer describes in detail.
During use, the aliphatic amide distillation residue enter in the thin-film evaporator through aliphatic amide residue material inlet 4 continuously, film forming under the rotation of the scraper plate in thin-film evaporator, on the thin-film evaporator inwall, heating heat-conducting oil about 280 ℃ of temperature in the well heater of thin-film evaporator and under vacuum state, the aliphatic amide that contains in the residue begins gasification, and enter condenser, purified steam carries out condensation by the round-robin water coolant in condenser, phlegma is collected in the distillate receiver, and will distill products obtained therefrom thus continuously and send through distillate outlet 6.Non-condensable gases is then extracted out through vacuum-pumping tube 12 by vacuum system.Unevaporated material is then discharged continuously through residue outlet pipe valve in thin-film evaporator, as final distillation residue.
Use shows, the aliphatic amide yield of the device of the extraction aliphatic amide of the utility model is compared with batch distillation still distillation mode and can be improved 5 percentage points, can loss-rate batch distillation still distillation mode reduce by 5%, and yet conformance with standard requirement of quality product does not need to distill once more.
