Device for refining crude diesel oil

Abstract

The invention relates to a biophore diesel oil extraction device, comprising a reaction groove body which can hold at least one reactant and a homogeneous reaction part. A circuit is formed by one pipe line of the homogeneous reaction part and the reaction groove body. The extraction device also comprises a shaft and at least one mix cutting body and the shaft is provided with at least one mix cutting body which can move along with the shaft to mix cut at least one reactant and drive at least one reactant to circulation. While in another better case, the homogeneous reaction part is provided with at least one mix cutting body which has a first pipe line, a plurality of branch pipe lines and a mixing cutting pipe. The first pipe receives at least one reactant, and a plurality of branch pipe line is communicated with the first pipe line to disperse at least one reactant; while the mix cutting pipe line is communicated with the plurality of branch pipe lines to receive at least one reactant collected from the branch pipe lines. Therefore, the reaction time of biophore diesel oil extraction is shortened, the energy consumption is decreased, the energy production is enhanced and the production cost is lowered.

Description

technical field [0001] The invention relates to a renewable energy generation device, in particular to a biodiesel refining device which performs mixed cutting circulation on biomass energy reactants to accelerate the reaction to generate biomass energy. Background technique [0002] Biodiesel has many advantages such as direct addition and use without modifying the diesel engine system, low pollution, high cetane number, etc., so its extraction technology has always been an important research and development direction of energy engineering. At present, the production methods of biodiesel can be roughly divided into alkali process, acid process, enzyme process and supercritical methanol process. Each process has its own advantages and disadvantages. For example, the reaction time of alkali process, acid process and enzyme process is longer and the fastest. The alkali process reaction also takes 1 hour, and the supercritical methanol process has a short reaction time, but it ...

Problems solved by technology

[0007] Although the enzyme production process has the above-mentioned characteristics, it is not easy to cultivate the enzyme and it needs to maintain its activity under specific environment and conditions, so the process steps become quite cumbersome during the transesterification reaction, for example, the reaction temperature needs to be fixed at 35 ℃, too high or too low ambient temperature will affect the activity of the enzyme. In addition, it is necessary to continuously add acetate during the process to maintain the pH value of the reaction environment. Depending on the increase in the reaction rate, it is necessary to add appropriate alcohol content and Only by maintaining a vibration frequency of 150 times per minute can the reaction [Ban K., Kaieda M., Matsumoto T., Kondo A., Fukuda H., "Whole cell biocatalyst for biodiesel fuelproduction utilizing Rhizopus oryzae cells immobilized within biomass supportparticles", Biochemical Engineering Journal Vol.8, p39-43, 2001.], all kinds of harsh conditions will make the mass production process relatively complicated, and what is more worrying is that, depending on the use of enzymes and methods, the reaction time is about It ranges from 6.3 to 72 hours. Compared with the simple, fast and high conversion rate of basic catalysts, this is also the main reason why the enzyme process is not widely used in mass production plants of biodiesel.

[0008] The supercritical methanol process can quickly carry out the transesterification reaction without adding any catalyst. According to the literature, a batch cycle can produce about 5ml of biodiesel in 3 minutes [S. Saka, D. Kusdiana, "Biodiesel fuel from rapeseed oil as prepared in supercriticalmethanol", Fuel Vol.80, p225-231, 2000], just because the supercritical process does not need to add any catalyst, so its reaction needs to add a large amount of alcohols, its oil and The mixing ratio of alcohols is 1:42 moles, and the amount of such alcohols used is 6 times that of the strong alkali process and 1.41 times that of the strong acid process; in addition, in order to quickly complete the transesterification reaction, the reaction needs to be It can only be completed under a high pressure and high temperature environment of 45-65MPa and above 350°C. This will increase the risk of the above-mentioned process and greatly increase the reaction cost. In addition, the current supercritical methanol process is limited by high-pressure and high-temperature reactions. Therefore, it cannot be used for mass production, and can only be produced in a small amount and analyzed in the laboratory. This is an urgent problem to be overcome when the described process is going to be mass-produced in the future.
