Embodiment
As Fig. 1 and Fig. 2, extraction process cottonseed protein circulation dephenolize device, comprises multi-stage spray extraction leacher 1, separating box 2, rectifying tower 9, condenser 19, methanol mother liquor case 3 and mother liquor pipe 13.Every grade of spraying and extracting leaches unit and comprises shower 12, end sieve tray dish 21, funnel case 5, Sprayer Circulation pump 16 and Sprayer Circulation pipe 15.Funnel cases at different levels 5 tops are communicated with, and raise step by step according to material direct of travel edge., mother liquor pipe 13 is connected respectively with Sprayer Circulation pipes 15 at different levels.
Between described leacher 1 and separating box 2, form external circulation, this external circulation structure is: between first step funnel case 5 tops of leacher 1 and separating box 2, establish the extraction liquid recycling pipeline 6 with variable valve 8, returning between jet pipe 11 of separating box 2 bottoms and leacher 1 first step top arranges methanol eddy pipeline 22, and is equipped with recycle pump 26 on recycling pipeline 6 and return line 22.
Between methanol eddy pipeline 22 and mother liquor case 3, rectifying loop is set, this rectifying loop is comprised of rectifying variable valve 7, rectifying tower 9, condenser 19, and condenser 19 is connected with mother liquor case 3.Between mother liquor pipe 13 and Sprayer Circulation pipe 15 at different levels, mother liquor variable valve 14 is set.
Described separating box 2 is precipitation, and separating box 2 inside establish two-stage and the unconnected vertical baffle 4a in top, 4b are divided into three parts by casing.Extraction liquid recycling pipeline 6 ends are in first part, and the initiating terminal of methanol eddy pipeline 22 is in the bottom of second section, and overflow port 17, recovery mouth 1 lay respectively at the upper and lower of third part.First step dividing plate 4a is higher than second stage dividing plate 4b, and establishes separating tube 10 on first step dividing plate 4a.The mixed solution that enters casing obtains stable and preliminary sedimentation layering in first part, and the organic solution on top climbs over dividing plate 4a and enters casing second section, and separating tube 10 imports the methanol solution of bottom at the middle part of second section.Mixed solution is in the further precipitate and separate of second section, and the organic solution on top climbs over dividing plate 4b and enters third part, and the phenol solution that contains of bottom enters return line 22.In third part, further the organic solution after precipitate and separate is collected from overflow port 17 the lixiviate workshop section directly returning in dephenolize, the methanol solution of bottom deposition temporary and after reaching finite concentration from reclaiming mouthful 1 pump to rectifying loop.The end of the recovery tube 6 in separating box 2 first parts arranges buffer cap 20, can make liquid phase stable as early as possible.
Material right-to-left on end sieve tray dish 21 is advanced in way step by step, in sprays at different levels unit, is sprayed step by step.Gossypol in material reduces step by step, thereby the methyl alcohol mixed liquor that contains organic solvent, gossypol is because concentration of component gradient disparities forms the anti-stream contrary with material direct of travel between funnel cases 5 at different levels, to the top of first step funnel case 5, is exported.Mixed solution is in settler 2 separation afterwards, and the top organic solution obtaining is returned to lixiviate workshop section, and the phenol solution part that contains of bottom is directly returned to supply dephenolizing extractor 1, and another part returns to methanol mother liquor case 3 after gossypol is removed in rectifying loop.
Utilize the variable valve 8 in extraction liquid recycling pipeline 6 can control the ratio that reclaims flow and circulation dephenolize flows at different levels.In like manner, utilize rectifying variable valve 7 to control to enter rectifying loop and directly enter the flow proportional containing phenol solution of extraction unit 1, in the present embodiment, both ratios are about 1:3.Again in like manner, utilize mother liquor variable valve 14 can control methanol mother liquor in the circulation tube 15 of lixiviate dephenolizes at different levels unit and the supply ratio of circulate soln, and alternation step by step, the ratio of specifically supplying with mother liquor declines step by step.
By increasing extract mixed solution recycling pipeline 6 flow, strengthen in rectifying loop containing the flow proportional of phenol solution, can make the content of gossypol in cottonseed protein constantly reduce.And due to the design in methanol loop loop, the supply consumption of fresh methanol is reduced.Reaching under cottonseed protein free phenol≤400ppm prerequisite, dephenolize workshop section energy efficient 30%, saves methyl alcohol more than 10%.Protein content >=50% in the cotton protein of producing, organic solvent≤500ppm, methyl alcohol≤800ppm.
