Description
Technical field
The utility model belongs to cottonseed processor technical field, relates in particular to a kind of mixed cotton seed oil evaporation separating device.
Background technology
With cottonseed through lint, peel off, cotton benevolence embryo sheet behind modified, the strip plate, oven dry is raw material, be extraction agent, lixiviate with non-polar solvent, separate and obtain mixing oil, mixed phenol liquid and the wet dregs of rice through polar solvent, mixing oil obtains hair cotton oil through evaporation concentration again, miscella concentration reaches at 51.17% o'clock under the normal pressure, and its boiling point is 81.3 ℃, and mixing oil separates used evaporation equipment and belongs to pressurized vessel in the prior art, use steam heating, the temperature height of oil, oil colours is deepened, the easy coking of vaporizer heating tube.
Summary of the invention
The purpose of this utility model is, overcome the deficiencies in the prior art, a kind of mixed cotton seed oil evaporation separating device is provided, under negative pressure, utilize the quality-adjusting device secondary steam to make thermal source, give the heating of first vaporizer, saved steam, reduced energy expenditure, vacuum state is evaporation down, temperature is low, guarantee quality of crude oil, reduced the usage quantity of recirculated cooling water simultaneously, reduced the water consumption.
For solving the problems of the technologies described above, the technical solution of the utility model is: mixed cotton seed oil evaporation separating device, comprise first vaporizer, first flash evaporation, second vaporizer, second flash evaporation, stripping tower, oil-in is arranged at the bottom of first vaporizer, the secondary steam import is arranged at top, the vapour outlet on the first vaporizer top and first flash evaporation pass through pipe connection, the oil-in of the oil outlet of the first flash evaporation bottom and the second vaporizer bottom passes through pipe connection, steam inlet is arranged at the second vaporizer top, the vapour outlet on the second vaporizer top and second flash evaporation pass through pipe connection, the oil outlet of second flash evaporation is connected with the oil-in of stripping tower, steam inlet is arranged at the bottom of stripping tower, and oil outlet is arranged at the stripping tower bottom.
First flash evaporation of the present invention is connected with vacuum system respectively with the top of second flash evaporation.
The top of stripping tower of the present invention is connected with vacuum system.
Mix oil pump to the mixing oil high level tank, by liquid level difference, secondary steam heating, mixing oil rises in first vaporizer, enter first flash evaporation after because that the space becomes suddenly is big, solvent becomes gaseous volatilization and goes out, mixing oil continues to enter second vaporizer and further concentrates, and enters stripping tower at last, by the effect of open steam, solvent residual in the mixing oil is removed, reached the crude oil standard.Whole evaporation process all is to operate under negative pressure, the purpose of negative pressure is exactly to reduce the boiling point of solvent in the mixing oil, the vaporization temperature of mixing oil is reduced, can make secondary steam utilized, the degree of oxidation of oil reduces, improved the quality of oil product, in operating process, the vacuum tightness-0.05MPa of first vaporizer and second vaporizer, stripping tower vacuum tightness-0.08MPa, the crude oil volatile matter is less than 0.01%, and impurity is less than 0.5%.
The beneficial effects of the utility model are: because mixed cotton seed oil evaporation separating device, comprise first vaporizer, first flash evaporation, second vaporizer, second flash evaporation, stripping tower, first vaporizer directly feeds secondary steam, vapo(u)rization system adopts full negative pressure evaporation, secondary steam utilizes, and energy-saving effect is obvious; Vaporization temperature is low, and oil product is of light color, and quality is good; Negative pressure in the system, evaporating, emitting, dripping or leaking of liquid or gas is few, and molten consumption is low, production safety.Mixing oil after filtration, the spinning liquid isolation of purified is handled, and reduces foreign matter content, again through negative pressure state next, two steam and stripping is handled, obtain crude oil.One vaporizer thermal source utilizes the secondary steam of dryer and evapo-separated machine, and two evaporations, stripping tower adopt indirect vapour heating, and about 25% steam is saved in the utilization of secondary steam, and has saved the investment of condenser, has saved water consumption; The crude oil volatile matter is low, and is of light color, and peroxide value is low, improved oil quality, improved the refining of crude oil refining yield and adopted the miscella refining technology, utilizes the quality-adjusting device secondary steam to make thermal source, gives vaporizer heating, saved steam, reduced energy expenditure; Vacuum state is evaporation down, and temperature is low, has guaranteed quality of crude oil, has reduced the usage quantity of recirculated cooling water simultaneously, has reduced the water consumption, and miscella concentration can reach 65%, can satisfy the production needs fully.
