Description
Technical field
The present invention relates to the production equipment of Organic chemical products plastic plasticizer, be specifically related to a kind of biological ester plasticiser low-boiling-point substance and remove continuously device.
Background technology
At present, when utilizing fatty acid methyl ester synthesising biological ester plasticiser, due to the methyl esters that contains the part low-boiling-point substance in fatty acid methyl ester, if not removing, these low cuts can not cause the open flash point of biological ester plasticiser finished product lower, directly have influence on the range of application of plasticizer.Generally adopt a distillation still in existing fatty acid methyl ester synthesising biological ester plasticiser production, can only accomplish to remove the purpose of moisture, low-boiling-point substance can't be removed, make product use the field limited.
Summary of the invention
The purpose of this invention is to provide a kind of biological ester plasticiser low-boiling-point substance and remove continuously device, realization is taken off low-boiling-point substance to product dehydrate when the synthesising biological ester plasticiser continued operation, not only production efficiency is high but also product quality is not only good but also stable.
For realizing above purpose, a kind of biological ester plasticiser low-boiling-point substance of the present invention removes continuously device and comprises the distillation receiving tank, has the low cut vaporising device and the vacuum plant that take off low-boiling-point substance and dehydrating function; Be provided with steam pipe coil, steam import and export, vacuum outlet, supplied materials entrance, recycle feed mouth, discharging opening, choke cover in described distillation receiving tank; Establish vacuum outlet, multistage evaporation dish, heating plate, multistage steam coil pipe and steam import and export, material inlet, material outlet in described low cut vaporising device; Described low cut vaporising device material outlet is connected with distillation receiving tank charging aperture pipeline, and distillation receiving tank discharging opening is connected and carries with pump with low cut vaporising device material inlet pipeline; Low cut vaporising device vacuum port be connected the receiving tank vacuum port and be connected with vacuum plant by pipeline respectively; All steam are imported and exported and are connected with superheated steam by pipeline.
Adopt the biological ester plasticiser low-boiling-point substance of said structure to remove continuously device, not only can make on the one hand product short in the time of staying of distillation receiving tank and low cut vaporising device, the product heating loss that has taken off after water and low-boiling-point substance is low, and due to the effective disengaging that has realized low-boiling-point substance, make the product open flash point high, smell is good, steady quality; The continuous feeding and discharging operating process is conducive to automation control on the other hand, enhances productivity.In addition, this biology ester plasticiser low-boiling-point substance removes continuously device and makes simply, and cost is low, is easy to promote.
Description of drawings
Accompanying drawing is that a kind of biological ester plasticiser low-boiling-point substance of the present invention removes the apparatus structure schematic diagram continuously.
The specific embodiment
Below by the drawings and specific embodiments, a kind of biological ester plasticiser low-boiling-point substance of the present invention being removed device continuously is described in further detail.
As shown in drawings, the biological ester plasticiser low-boiling-point substance of the present invention removes continuously device and comprises that distillation receiving tank 7, low cut vaporising device 25 and vacuum plant 33 form; The distillation receiving tank is provided with supplied materials entrance 4 and recycle feed mouth 14, discharging opening 8, choke cover 3, vacuum outlet 2, steam inlet 5 and 6 and steam (vapor) outlet 13; Low cut vaporising device is provided with supplied materials entrance 23, discharging opening 16, choke cover 28, vacuum outlet 26, steam inlet 29,30,31,32, evaporating pan 18,20,22, heating plate 17, blast pipe 19,21,24; Low cut vaporising device discharging opening 16 is connected with distillation receiving tank recycle feed mouth 14 pipelines, low cut vaporising device vacuum port 26 be connected receiving tank vacuum port 2 and be connected with vacuum plant 33 by pipeline respectively, all steam are imported and exported and are connected with superheat steam pipeline, and distillation receiving tank material liquid outlet 8 is connected with low cut vaporising device import 23 and uses pump 10 to carry.
during operation, open vacuum plant 33, open valve 1, valve-off 27, opening steam 5 and 6 will distill in receiving tank material and heat up and add the heat abstraction most of moisture, and then drive valve 27, valve 15, valve-off 1, open valve 9 and valve 12, valve-off 11, opening pump 10 is extracted into material in low cut vaporising device and opens simultaneously all steam that hang down in the cut vaporising device, steam is from steam inlet 29, 30, 31, 32 enter, in the evaporating pans at different levels of feed liquid in low cut vaporising device and heating plate with after steam contacts, low-boiling-point substance and steam form azeotropic mixture by blast pipe 19, 21, 24 are discharged to vacuum port 26 and utilize vacuum to extract out, the material that has taken off after water and low cut is got back to the distillation receiving tank, open valve 11 valve-offs 12 through pump 10 and be transported to the finished product storage tank.
