Description
Technical field
The utility model relates to a kind of wet dregs of rice desolventizing machine of producing the high temperature dregs of rice, exactly relates to a kind of energy-conservation continous way desolventizing machine that continuous leaching device removes the high temperature dregs of rice of liquid extractant in the dregs of rice that dry that is used for.
Background technology
Leaching is widely used in oil prodution industry continuously; As from various natural oil plants, plant kernel, extracting vegetables oil; Be applied in addition to refine sugar, effective constituent obtains through refining and the extraction of spices etc. in the plant concentration protein, foodstuffs industry, chemical industry, herbal medicine; Employed extraction agent also is solvent, and common have nonpolar hydro carbons such as normal hexane, polar alcohols such as ethanol, a water etc.
Still the extract remainder that contains extraction agent behind the completion extraction process is commonly called as the wet dregs of rice.No matter which kind of type employed extraction agent is; Even water; Also need solvent be separated from product, this process is called wet dregs of rice precipitation, adopts mechanical process as draining, squeezing, can only remove the part surface solvent; The most of solvent that exists in the wet dregs of rice all need pass through heating power method precipitation just can reach safety, economic, the requirement that is suitable for, and this heating power method desolventizing machine promptly is the related continuously wet dregs of rice desolventizing machine of the utility model.
At present, in industry, produce the wet dregs of rice desolventizing machine of the widely used main flow of the high temperature dregs of rice: the one, the high bed of material steaming-drying machine of former German LURGI exploitation is mainly used in into immersion and divides lower solid material; The one, the DT that on schumacher patent basis, develops (precipitation-roasting dregs of rice), DTDC (precipitation-roasting dregs of rice-drying-cooling) etc.These two kinds of desolventizing machines all are knockdown, comprise the identical operations unit: (1) delamination in advance, and adopt dividing wall type to conduct heat (water vapour does not contact with the wet dregs of rice), be used to improve wet dregs of rice temperature and its surface solvent of appropriateness evaporation; (2) stripping layer utilizes the principle of steam distillation, and water vapor contacts with the wet dregs of rice, and passes the whole wet dregs of rice bed of material from bottom to top, and a part of water vapor is used to reduce the dividing potential drop of desolventizing machine internal solvent, is called not condensing open steam; A part is used to provide material to heat up and the required heat of solvent evaporation, becomes condenses water and gets in the dregs of rice, is called condensing vapour.More than the steam consumption of three aspects constituted the total water vapor consumption of wet dregs of rice desolventizing machine.
Structurally, these desolventizing machines also interosculate: (1) vertical structure, and heteroid circular tower tray forms the different operation unit, and the stirring wing of each layer tower tray is by a main shaft drives; (2) solvent vapo(u)r and the water vapor of desolventizing machine generation are drawn by same outlet from the top of desolventizing machine; (3) require the desolventizing machine head can form little negative pressure, return leacher to avoid too much solvent to leak with not condensing water vapor.Different tray diameter, the preparatory delamination of different quantities and stripping layer have formed industrial miscellaneous wet dregs of rice desolventizing machine of, and have also determined the height of wet dregs of rice desolventizing machine energy consumption.
Because the industrial use of leaching is wider, it is indispensable particularly to produce industry at the edible oil that involves the interests of the state and the people.In a large amount of factory's actual productions, be difficult to guarantee that the desolventizing machine head does not produce malleation, also just mean to produce more solvent leakage and water vapor entering leacher.And for specific factory and the wet dregs of rice desolventizing machine that used, almost no longer possibly reduce at the energy of wet dregs of rice desolventizing machine consumption, according to measuring and calculating; The heat that wet dregs of rice desolventizing machine is consumed accounts for more than 60% of whole leaching device, and therefore, the heat exhaustion that reduces wet dregs of rice desolventizing machine has very big realistic meaning; Such as the domestic annual oil plant total amount that gets into the leaching device of China more than 6,000 ten thousand tons; If raw material per ton reduces steam consumption 10kg in wet dregs of rice desolventizing machine, be equivalent to the whole industry and can practice thrift 600,000 tons of water vapors every year, water vapor per ton is 300 yuan of calculating at current price; Can practice thrift the energy expenditure of nearly 200,000,000 Renminbi, also reduce a large amount of CO simultaneously
