[0003] 高于溶剂沸点温度但低于溶剂临界温度的温度区间,被定义为溶剂的亚临界状态,这也是溶剂气体的液化状态,以此状态的溶剂对物料进行萃取,被称为亚临界萃取。 [0003] The solvent having a boiling point higher than the temperature range of temperature but below the solvent critical temperature, is defined as a subcritical state as a solvent, which solvent gas is liquefied state, the solvent in this state the material was extracted, is called subcritical extraction. 专利号为ZL90108660.6的现有技术,公开了一种《液化石油气浸出油脂工艺》,属于最早的亚临界萃取专利。 Patent No. ZL90108660.6 prior art, discloses a "LPG extraction process oils", among the first patent subcritical extraction. 由于亚临界萃取溶剂具有一定的压力,例如丁烷萃取罐的萃取压力一般是5个大气压,将大气环境下的固体物料连续地装入高压工作的萃取装置有一定的困难,所以,目前在工业中实际应用的亚临界萃取工艺及设备,都是罐组式的间歇生产方法,是将物料装入敞口的萃取罐后,关闭进料口,再打入溶剂进行亚临界萃取,并且要在罐内物料脱除溶剂后,在压力达到OMPa以下时才能排料。 Since subcritical extraction solvent having a certain pressure, such as extraction pressure butane extraction tank is generally 5 atmospheres, the solid material extraction apparatus under a high pressure atmosphere is continuously charged work is somewhat difficult, therefore, currently in the industry subcritical extraction process and equipment in practical applications, batch production methods are of pot groups, the material is loaded after the extraction tank open and close the feed port, and then into the sub-critical extraction solvent, and to the after removal of the solvent the raw material inside, to discharge when the pressure reaches less OMPa. 一组6罐的罐组要安装70多个阀门,操作很复杂、极易误操作、产量小、生产不稳定。 A group of six cans 70 can set a plurality of valves to be installed, the operation is very complicated, highly erroneous, production of small, unstable production. 为了实现亚临界萃取的连续化,申请号201310197516.5《一种连续浸泡浸出油脂设备及工艺》公开了一种亚临界连续萃取方法,该方法用两级进料筒将物料连续加入浸泡室,进料操作繁琐;浸泡室与链斗式浸出器联通的结构,不能实现较高的混合油浓度,降低了萃取溶剂的利用率;在湿柏储罐与柏减压脱溶罐与柏真空脱溶罐之间用关风器阻断三罐之间的压力差实际是很难实现的,目前尚没有能够阻断0.2MPa压差的关风器,何况丙烷溶剂与真空压差达0.9MPa,另外,物料中溶剂蒸发需要大量吸热,柏减压脱溶罐与柏真空脱溶罐都没有设计热量补给机构,最终的成品柏会以很低的温度和很高的含溶排出。 In order to achieve the continuous subcritical extraction, Application No. 201310197516.5, "A continuous immersion oil extraction equipment and technology" discloses a continuous subcritical extraction method of the material into a cylinder with two continuous addition of the infusion chamber, feed complex operation; soaking chamber paternoster extractor Unicom structure, mixing can not achieve a high oil concentration, reducing the efficiency of the extraction solvent; wet tank and Bo Bo Bo vacuum tank and vacuum desolventizing desolvation tank between a blocking pressure between the three cans difference between the actual airlock it is difficult to achieve, yet not capable of blocking the airlock pressure 0.2MPa, not to mention the solvent in vacuo propane pressure of 0.9MPa, additionally, the solvent was evaporated material requires highly endothermic, Bo Bo vacuum tank and vacuum desolventizing desolvation tanks are not designed to heat supply means, the final product will be discharged Bo very low temperature and high-containing solution. 申请号201320359608.4《亚临界流体连续萃取装置》公开的方案中,物料从大气空间进入压力为5个大气压以上的萃取器,使用了两级旋转密封进料阀,但两级之间的物料中有上阀带入的空气与下阀带入的溶剂气的混合气,混合气经真空栗进入系统,同理,两级旋转密封连续出料阀也会带入大量空气,系统内会很快集聚空气,系统压力很快上升,而排出系统内空气时又会有大量溶剂气体一起排出,既危险又浪费溶剂;方案中的萃取器实际是一种大豆等植物油料浸出常用的履带式浸出器结构,但亚临界萃取是在压力下完成的,这种履带结构要使用压力容器的外壳就显得设备结构的不合理;一级脱溶器和二级脱溶器的连续脱溶方法,使两脱溶器的压力差很大,很难保证二级脱溶器的真空度,也就难于保证出柏的溶剂残留的合格。 Disclosed embodiment "subcritical fluid continuous extraction apparatus" Application No. 201320359608.4, the material from the atmosphere into the pressure space 5 above atmospheric extractor using two rotary seal inlet valve, but there is material in between the two and an air valve into the aerosol valve into a mixed gas, the mixed gas enters the system through the vacuum Li, similarly, two continuous rotary seal into the valve will be a lot of air, the system will quickly gather air, system pressure increases rapidly, and the exhaust air system time and have a lot of gas is discharged together with the solvent, the solvent is dangerous and wasteful; extraction schemes actual plant is a soybean oil leaching leaching conventional crawler structure , but the sub-critical extraction is done under pressure, such a track configuration to be used in a pressure vessel housing equipment configuration becomes unreasonable; desolvation and a desolvation two continuous filter desolventizing methods, so that the two off differential pressure melting is large, it is difficult to ensure a degree of vacuum filter two desolvation, it is difficult to ensure that the qualified solvent remaining cedar. 申请号201510853263.1《一种低温亚临界流体萃取装置》公开的技术方案中,采取料塞封堵的进料螺旋阻断萃取罐的亚临界高压溶剂泄漏,此结构不易控制进料,料塞太松会有溶剂泄漏,而亚临界溶剂是易燃易爆的液化气,必须保证密封安全,不能有任何隐患,这是此结构难于做到的;料塞太紧很容易形成滑膛,使螺旋与物料一起在筒中旋转,物料不再前进,在实际生产中物料的性状变化很大,这种料塞密封结构很难保证稳定的生产;该方案中的萃取罐过于简单,物料连续进入萃取罐后,未达到萃取效果即被下降到出料口,萃取液的浓度也会太低,不能实现逆流萃取,溶剂利用率低;该方案的脱溶罐里连续地进入高含溶的物料,罐内会持续有较高压力,溶剂浓度会很大,排出脱溶罐的萃取渣不易脱净溶剂,既浪费溶剂又产生很大的安全隐患。 Application No. 201510853263.1 disclosed aspect "subcritical cryogenic fluid extraction device", a high pressure solvent subcritical taken leak plugging material feed screw plug blocking the extraction tank, this structure is difficult to control the feed, feed too loose plug the solvent will leak, and the flammable solvent is a subcritical gas, must ensure safety seal, can not have any problems, the structure of which is difficult to do this; tight material plug is easy to form smooth-bore, with the coil material together with the rotation in the cartridge, the material is no longer proceeds, a large variation in the actual mass production traits, such material is difficult to ensure a plug seal structure and stable production; extraction tank in this solution is too simple, continuous material enters after extraction tank, i.e. extraction efficiency does not reach down to the discharge port, the concentration of the extract will be too low to achieve a countercurrent extraction, the use of low solvent; desolvation jar continuously into the solution containing the high melting material, the tank will continue to have the higher pressure, the solvent concentration will be large, discharging the slag removing solvent extraction can not easily off the net solvent, a waste solvent and have a great security risk.
