Description
Technical Field
The invention belongs to the field of extractors, and particularly relates to an extractor control system based on a buffer adjustment technology.
Background
With the development of petrochemical industry, liquid-liquid extraction has been widely used for separating various organic substances, and separation of aromatic hydrocarbon mixtures produced by cracking of light oil and reforming of platinum is an important example. The boiling points of the components of the mixture are very close, making it uneconomical to use a common separation method. The extraction process of Udex, She l, Formex, etc. is adopted in industry, and uses cyclobutes, tetraethylene glycol and N-methyl pyrrole kang ketone as solvent to extract arene from reformed oil of pyrolysis gasoline. For an ethylbenzene system difficult to separate, the relative volatility of the components is close to 1, the reflux ratio is large by using a rectification method, the number of tower plates is up to 300, and the operation cost is extremely high. Xylene and its isomers can be separated from the C8 fraction by an extraction operation using HF-BF3 as extractant.
In the course of the preparation of biochemical drugs, very complex mixtures of organic liquids are formed, these substances being mostly heat-sensitive substances. If proper solvent is selected for extraction, the heating damage can be avoided, and the yield of effective substances is improved. For example, penicillin is produced by fermenting corn to obtain a fermentation liquor containing penicillin, and extracting the fermentation liquor for multiple times by using acetic acid butyl enzyme as a solvent to obtain a concentrated solution of penicillin. In addition, the extraction operation is adopted for the production of the medicines such as streptomycin, compound sulfamethoxazole and the like, so that a better effect is obtained. The method for extracting vanillin from sulfite pulp wastewater by using n-propanol in the flavor industry and extracting citric acid from fermentation liquor by using TBP in the food industry are widely applied. It can be said that extraction operations have already taken an important position in the pharmaceutical industry, fine chemistry.
Since the 40 th century in 20 years, a great deal of research and development has been focused on refining uranium, thorium, plutonium and other metals due to the development of the atomic energy industry, and as a result, the extraction method almost completely replaces the traditional chemical precipitation method. In recent 20 years, the use amount of non-ferrous metals is increased sharply, and the grade of the mined ores is reduced year by year, so that the extraction method is promoted to be developed rapidly in the field. The extraction of copper from copper leaching solutions with a neoplasmic extractant such as solvent L IX63-65 was one of the important achievements in wet liquefaction of gold since the 70's of the 20 th century. It is currently believed that extraction by solvent extraction should be preferred as long as non-ferrous metals such as cobalt, nickel, zirconium, etc., which are as expensive as or exceed copper. Non-ferrous metal smelting has gradually become an important field of solvent extraction application.
However, the vibration of the extracting machine is large in the working process at present, the damping mechanism needs to be adjusted for multiple times, the adjusting process of each time is complicated and inconvenient, and a technical scheme for effectively solving the problem of the vibration of the machine body in the extracting process is not found in market research and document data retrieval at the present stage.
