Description
Technical field
The utility model relates to chemical industry equipment field, relates to particularly a kind of energy saver of preparing epoxidized soybean oil.
Background technology
Epoxidized soybean oil, have another name called epoxy glycerite three acid esters, a kind of chemical products synthetic taking edible soybean oil as primary raw material, its main component is undersaturated fatty acid glyceride (as epoxy linoleate, Epoxy oil acid esters etc.) mixture, and contain the impurity such as a small amount of pigment, phosphatide, colloid, be light yellow oily liquid.Epoxidized soybean oil belongs to epoxy plasticiser, it is the most frequently used PVC auxiliary stabilizer, low price, nontoxic, mainly as extender plasticizer, heat stabilizer, be applicable to the soft goods of moulding of all PVC at present, as: plastic sheeting for farm use packaging film, artificial leather, slippers sandals rain boots, inflatable toys, polybag, flexible pipe, electric wire crust, Medical transfusion bag stilligout, mould ground cushion, fire hose, plastic gloves, sealing strip, coating layer, wallpaper, also can be used for special ink, liquid composite stabilizing agent etc.
In polyvinyl chloride resin processing, it not only has plasticization to PVC, and because the epoxide group in structure can catch the PVC isolated free radical of degrading, can absorb rapidly the HCL that degrades out because of light and heat, stop the de-HCL of PVC to decompose, the free responding that stops PVC degraded, slows down degradation speed, thereby extends the service life of PVC goods.Because epoxide group has significantly improved fast light, the heat-resisting and oil resistivity of PVC goods, can give mechanical strength, weatherability and electrical property that goods are good.Epoxidized soybean oil belongs to pure organic compound stabilizing agent, conventionally with metal salt stabilizers also with producing cooperative effect, effectively improve stability.Organic auxiliary stabilizer is widely used, and is specially adapted to the formula of liquid composite stabilizing agent.In addition, epoxidized soybean oil has crosslinked toughness reinforcing effect to PVC goods, can improve that PVC is fast light, heat-resisting, anti-aging, shock resistance, lubricated oozing property, low temperature flexibility mutually, and volatility is low, there is no the performances such as toxicity, quite extensive at food and medicine trade application.The epoxidized soybean oil of being prepared by renewable plant resources, as the friendly plasticizer of novel environmental of superior performance, be subject to showing great attention to of more and more Plastics Processing Industries and plasticizer production enterprise, being regarded as one of favorable substitutes of phthalic ester plasticizer, should be the direction that plasticizer industry product is adjusted.
Epoxidized soybean oil traditional processing technology is: in reactor, add the edible soybean oil of iodine value more than 130, under agitation, add peroxyformic acid in batches, control reaction temperature at 65～75 DEG C, because epoxidation reaction is exothermic reaction, for making reaction in steady safe condition, need in reacting kettle jacketing, inject cooling water and carry out circulating cooling, peroxycarboxylic acid is fully reacted with two keys, when product epoxide number reaches 6.3 when above, stop stirring stratification, remove lower floor's water, oil phase is waited until subsequent handling processing.
Owing to still having the impurity such as organic acid, catalyst of some in oil phase after epoxidation reaction, must remove by washing.Generally first wash with water once, then wash once with dilute alkaline soln, be finally washed with water to grease and be neutral, after washing water-oil separating, adopt conduction oil or Steam Heating to be warming up to 85～95 DEG C; Then adopt decompression distillation to remove moisture content and low boiling impurity, obtain final product epoxidized soybean oil.In traditional handicraft, after epoxidized soybean oil water washing, need to use conduction oil or Steam Heating, will, with electrical heating or other mode of heating, increase energy consumption.
Conventional process flow is as follows:
Peroxyformic acid---soybean oil---stratification---water washing---sodium hydroxide solution washing---water washing---conduction oil (or steam) heating---decompression distillation---epoxidized soybean oil
In traditional processing technology, if do not use hot wash while washing, can make oil phase and water not easily separated, grease temperature declines, and extends the production time; After washing and alkali cleaning, grease temperature generally drops to below 75 DEG C, cannot carry out smoothly decompression distillation, for making temperature reach 85～95 DEG C, must use steam or conduction oil to heat soybean oil, then decompression distillation, needs a large amount of energy consumptions and prepare in conduction oil or steam course, increases production cost.In heating process, also there is the problem of a heat time, if the time is oversize, can make grease excess Temperature, can shorten distillation time although temperature is higher, can cause color with oil color to deepen, follow-up decolouring is processed more difficult.
Utility model content
The purpose of this utility model is to provide a kind of energy saver of preparing epoxidized soybean oil, to solve the above-mentioned problems in the prior art.
The technical scheme that the utility model provides is as follows:
A kind of device of preparing epoxidized soybean oil, it is characterized in that: comprise reactor (1), diversion three-way valve (2), cooling tower (4), circulating water pool (5), converging three-way valve (7) and heat preserved water can (9), wherein, the housing of reactor (1) is provided with cooling jacket layer (13) outward, this cooling jacket layer (13) be provided with cooling water intake (14) and cooling water outlet (15), cooling water outlet (15) connects diversion three-way valve (2), the first delivery port of this diversion three-way valve (2) is connected to cooling tower (4), the outlet of cooling tower connects circulating water pool (5), the delivery port of circulating water pool (5) connects the first water inlet of a converging three-way valve (7), the cooling water intake (14) of the delivery port coupled reaction still (1) of converging three-way valve (7), the second delivery port of diversion three-way valve (2) connects a heat preserved water can (9), and the delivery port of this heat preserved water can (9) is connected with the second water inlet of converging three-way valve (7).
