Description

Monoterpene compound purification device Technical Field The invention relates to the technical field of purification of monoterpene compounds, in particular to a monoterpene compound purification device. Background The monoterpene compound is widely applied to natural products such as plant essential oil, resin and the like, has various biological activities such as antibiosis, anti-inflammatory, aromatic flavoring and the like and industrial values, and has wide application prospect in the fields such as medicines, spices, food additives and the like. The separation and purification of the monoterpene compound is a key link of the industrialized application, wherein the liquid-liquid extraction method is one of the main processes of the current monoterpene compound purification due to the advantages of simple operation, low energy consumption, strong applicability and the like. The core principle of liquid-liquid extraction for purifying monoterpene compounds is to utilize the solubility difference of monoterpene components in the raw material liquid and the extraction liquid to realize the transfer of the monoterpene components from the raw material liquid to the extraction liquid (namely, the mass transfer process), and the mass transfer efficiency directly determines the extraction purity, the extraction yield and the production efficiency of the monoterpene compounds. In order to improve the mass transfer effect, the conventional liquid-liquid extraction device is generally provided with a filler structure in an extraction tower, the contact area of two-phase liquid is increased through the filler, the laminar flow state of the liquid is broken, and the mass transfer resistance is reduced. At present, most of the commonly used extraction tower packing is fixed packing (such as pall rings and raschig rings) or static elastic packing, and forms a liquid circulation channel through a self structure to assist two-phase mixing. However, in practical application, the structural characteristics of the packing determine that a fixed flow path is easy to form in the circulation process of the liquid, and sufficient dynamic mixing is difficult to realize, so that the problems of insufficient mass transfer efficiency, poor extraction uniformity and the like still exist in the purification process of the monoterpene compound, and further improvement of the purification quality and the production efficiency of the monoterpene compound is restricted. The filler structure adopted by the existing monoterpene compound liquid-liquid extraction and purification device has the following technical problems in the actual operation process, and affects the purification effect and production efficiency of the monoterpene compound: 1. The mass transfer resistance is high, and the transfer efficiency of the monoterpene component is low. The existing fixed or static elastic packing has fixed flow channels, liquid flows in laminar flow state at packing gaps and on the surface, two-phase liquid can only realize limited contact on the packing surface, and sufficient interpenetration and mixing are difficult to form, so that mass transfer resistance between the two phases is large, and the transfer rate of monoterpene components from raw material liquid to extract liquid is slow, thereby influencing the extraction yield and production efficiency of monoterpene compounds. 2. The dead liquid area is easy to form, and the extraction uniformity is poor. Because the filler structure is fixed, liquid is easy to form fixed channeling along the filler gap in the flowing process, and partial area liquid flow stagnates to form a dead liquid area. The raw material liquid in the dead liquid areas cannot be effectively contacted with the extraction liquid to participate in mass transfer reaction, so that not only is the raw material wasted, but also the extraction degree of monoterpene components in different areas in the extraction tower is inconsistent, the purity stability of the purified monoterpene compounds is finally influenced, and the problem of local purity fluctuation occurs. Disclosure of Invention The invention aims to solve the problems that the existing packing structure adopted by the liquid-liquid extraction and purification device of the monoterpene compound has large mass transfer resistance, low monoterpene component transfer efficiency, easiness in forming a dead liquid region and poor extraction uniformity in the actual operation process, and influences the purification effect and production efficiency of the monoterpene compound, and provides a high-efficiency monoterpene compound purification device. The technical scheme includes that the monoterpene compound purifying device comprises an extraction tower and a plurality of filling frames fixedly connected to the inner side of the extraction tower, a plurality of elastic filling balls, a friction auxiliary device and an extrusion auxiliary piece, wherein the elastic fill
