Current, the suitability for industrialized production of biofuel adopts the homogeneous catalysis esterification to reduce the waste oil acid number mostly both at home and abroad, is generally dense H
2SO
4Though catalytic efficiency (is higher, its shortcoming is also very outstanding.Especially show: liquid acid has corrodibility to equipment; Catalyzer and reaction product separation difficulty are difficult to recycling, and a large amount of spent acid solution dischargings are arranged in the last handling process, and environmental pollution is serious.And in the production of biodiesel process, adopt solid acid catalyst to substitute liquid acid, and make product and catalyst separating easy, can avoid the discharging of a large amount of waste liquids, effectively prevent the pollution of the environment; Simultaneously solid acid have reactive behavior height, selectivity good, easily separated, can be recycled, to advantages such as conversion unit corrodibility are little.Have and reduce production costs, simplify technical process, be convenient to the characteristics of operate continuously.Therefore, exploitation use solid acid catalyst is trend of the times.Equally, when using solid acid catalyst, one be convenient to operate, solid acid reaction kettle that efficient is high also is equal important.
The utility model content
Energy-conservation in the preparatory esterification process when purpose of the utility model is production of biodiesel is provided, be convenient to operation, preparatory esterification of biodiesel oil solid acid catalysis and methyl alcohol reclaim reaction kettle continuously, to reduce the production of biodiesel cost.
For realizing above purpose; The technical scheme of the utility model is following: preparatory esterification of biodiesel oil solid acid catalysis and methyl alcohol reclaim reaction kettle continuously; Include cylindrical shell, be located at the grease import of cylindrical shell lower end, be provided with the gas-phase methanol outlet on said cylindrical shell top; Directly be connected with condensing surface in the gas-phase methanol outlet, can make things convenient for Methanol Recovery and can reduce equipment; Cylinder inboard wall 1/20～1/10 place is provided with the circular arc tongue, and circular arc tongue forward position is provided with filter screen; Cylinder inboard wall 1/20～1/10 place is provided with the grease outlet, and the grease outlet directly is connected with the circular arc tongue, can realize greasy continuous discharging; Be provided with spiral heater in said barrel, directly grease heated to reach the temperature of methanol gasifying fast, the cylindrical shell inner surface is provided with insulation jacket.
Reaction kettle cylindrical shell height and reaction kettle internal diameter are than H: D >=3, so that grease and gas-phase methanol have the competent reaction times.
The side of cylindrical shell lower end, grease import is provided with the filtration piston of arbitrarily dismounting, can make things convenient for regular replacing solid acid catalyst.
When having the biofuel actual production now; Often add reaction masses such as wanting raw material such as pretreated high-acid value grease such as acidifying oil or waste oils and fats and catalyzer, excess liq methyl alcohol in the reactor drum; Make raw material carry out esterification reaction of organic acid, the water that in the esterification reaction of organic acid process, generates rests in the methyl alcohol and has influenced reaction.Make grease while reacting the method for evaporating methyl alcohol through special reaction kettle, gas-phase methanol can be taken the water that reaction generates out of.
The utility model compared with prior art; Has following advantage: handled easily; Reduced equipment cost, realized in the production of biodiesel high-acid value grease continuously in advance esterification reclaim continuously with methyl alcohol, significant to promoting the biofuel large-scale development with production.
