Description
Technical field
The present invention relates to environmental protection equipment, specifically is the reaction unit of a kind of manufacturing biofuel (fatty acid methyl ester).
Background technology
Biofuel (Biodiesel) is meant the diesel regenerated fuel with the replaced petrifaction diesel that to be raw oil process through esterification, ester exchange process such as animal-plant oil or microbial oil, mainly is fatty acid methyl ester.Biofuel has special advantages, its alternative petrifaction diesel, and direct or mediation is used for existing diesel motor, becomes one of biomass fuel that is favourably welcome.
Reaction system from biodiesel manufacture; Grease and methyl alcohol are immiscible system; Mass transfer is one of important factor of influence reaction, and from the thermodynamics angle, the transesterification reaction of grease and methyl alcohol is the thermodynamic(al)equilibrium reaction; Breaking the thermodynamic(al)equilibrium process is one of important method that improves the unit space-time yield, reduces production costs, and these procedure problem all need solve from the design of reaction unit.Therefore, in the biofuel manufacturing processed, reaction unit is one of nucleus equipment in the biofuel manufacturing processed.
There is following shortcoming in prior biological diesel oil reaction unit: (1) complex structure, energy consumption is big, three wastes discharge amount is big, environmental pollution is big; (2) complex manufacturing, long reaction time, that the workman operates labour intensity is big; (3) production efficiency is low, production cost is high.
Summary of the invention
In order to overcome the deficiency of prior art; The present invention provides a kind of reaction unit of making biofuel; This reaction unit is simple in structure, reasonable in design, production energy consumption is low, is applicable to waste animal and vegetable oil (like sewer oil, hogwash fat, plant-animal oil foot, acidifying oil) and microbial oil manufacturing biofuel.
The technical scheme that the present invention adopts is: comprise reaction kettle, Methanol Recovery condensing works, recycle pump, solid catalyst filled column, ultrasonic generator.Said reaction kettle top is respectively equipped with raw oil opening for feed, methanol feeding mouth and Methanol Recovery condensing works, and the reaction kettle bottom is provided with discharge port; Said recycle pump is series on the reaction solution circulation line; Filler in the said solid catalyst filled column is respectively solid acid catalyst and solid base catalyst, and solid acid catalyst filled column and solid base catalyst filled column are parallel on the reaction solution circulation line; Said ultrasonic generator transverter places solid catalyst filled column internal reaction liquid loop head place.
Said ultrasonic generator can be a microwave generating apparatus.
Said recycle pump is high speed shear pump, impeller pump or toothed gear pump.
The present invention compared with prior art has the following advantages and effect: be parallel to solid acid catalyst filled column and solid base catalyst filled column on (1) reaction solution circulation line; Can select solid acid catalyst filled column or solid base catalyst filled column, flexible operation for use according to the different characteristics of raw oil; (2) reaction kettle is not established whipping appts, and the glycerol liquor that reaction is generated sinks to the reaction kettle bottom naturally, can not enter into the catalytic efficiency (that the solid catalyst filled column influences solid catalyst, thereby change the equilibrium state of reaction system, and it is more thorough that reaction is carried out; (3) the UW radiation makes the reaction solution in the closed cycle pipeline occur emulsified state rapidly, and produces a large amount of cavitation bubbles continuously, and cavitation bubble increases rapidly; Acutely collapse in the packing layer of solid catalyst is housed subsequently, and produce fierce localized hyperthermia's high pressure, reaction solution is fully stirred with catalyzer to be mixed, emulsification; The chemical reaction interface is enlarged rapidly; Under identical reaction conditions, more help quick biodiesel synthesis, shortened the reaction times, lowered production cost greatly.
