Abstract
The invention relates to hydrolysis tower for biodiesel production. The bottom of tower is equipped with a steam distributor and fixed with rib to tower inner wall; there is space between all- around of steam distributor and tower inner wall, the outlet of steam inlet pipe is fixed below steam distributor; the top of tower is connected to a water separator; oil inlet is located on the top of tower, and the hydrolyized material outlet is at the bottom of tower. The invention is characterized by simple structure, easy production, high oil availability ratio of over 98.5%, increased biodiesel productivity by more than 30%, reduced production cost and environmental pollution, and increased industrial benefit.
Description
One, technical field
The present invention relates to the equipment in a kind of production of biodiesel.
Two, background technology
Production biofuel in countries in the world mainly is to produce with chemical method at present, but the main ester-interchange method production biofuel that adopts in chemical method is produced, realization is carried out refining with grease with chemical method and physics method, reached edible and salad oil standard, can make polished fat and methyl alcohol carry out transesterification reaction.If the oil and fat refining poor quality will make being affected of transesterification reaction, reduce the transformation efficiency of tri-glyceride.For example at present in the world in the production of biofuel the transformation efficiency of tri-glyceride generally about 85%, that is to say, still there is the neutral oil about 15% to exist in the biofuel, these medium-sized oil and methyl esters mix and be difficult to vaporization in the automobile cylinder barrels, produce carbon deposit, adding the existence of other impurity in addition, is substandard product certainly.Use so abroad can only biofuel be joined in the ordinary diesel oil with the ratio of 5-10% at present.
If with oil and fat refining, be that its acid value reaches below 0.2, carry out the transesterification reflection again, then oil loss increases, and general yield is about 70%, that is to say, still there is 30% neutral oil to become oil foot, and the oil foot maturation process route of not production biofuel also in the world at present, this just causes the grease utilization ratio to reduce, the problem that production cost raises, and produce a large amount of oil foot contaminate environment.
Carry out the transesterification reflection again if neutral oil is hydrolyzed, 30% the oil foot that produces in the time of just can making refining oil is rationally utilized, but except that the inventor, also have no talent hydrolysis process is applied in the production of biofuel, and the hydrolysis device that uses both at home and abroad at present also is not suitable for the production of biodiesel use.Present hydrolysis device mainly contains stirring-type and flings the vapour formula, and these equipment are not only invested greatly, and hydrolysis time is long, percent hydrolysis is low.
Three, summary of the invention
The technical problem to be solved in the present invention is: design a kind of hydrolysis device that is applicable to that production of biodiesel technology is used, to improve grease utilization ratio and bio-diesel yield.
The technical scheme that solution the technology of the present invention problem is taked is: establish a steam distributor in the tower body bottom, steam distributor is an arc plank frame, circular arc upwards, be fixed on the tower body inwall by rib, leave the gap with the tower body inwall around the steam distributor base, the outlet of steam input pipe is located at the below of steam distributor, and perpendicular to the bottom of steam distributor; The external steam separator in tower body top; The oil plant inlet is located at the tower body top, and the material outlet after the hydrolysis is located at the tower body bottom.According to processing requirement, the diameter aspect ratio of hydrolysis tower is 1: 10-1: 12.
Positively effect of the present invention is: simple in structure, make easily, use it for the hydrolysis process of biofuel, greasy utilization ratio is reached more than 98.5%, bio-diesel yield improves more than 30%, makes the oil foot waste material obtain comprehensive utilization, not only greatly reduces production cost, and reduced environmental pollution, improved economic benefit of enterprises.
Four, description of drawings
Accompanying drawing is a structural representation of the present invention.
Five, embodiment
With thickness is the Gr18Ni9Ti plate of 14mm, the hydrolysis tower of weldering system diameter 1000mm, a tower height 12000mm, establish a steam distributor 3 in tower body 2 bottoms, steam distributor 3 is arc plank frames, and circular arc makes progress, and mouth downwards, be fixed on tower body 2 inwalls by rib 4, leave the gap with the tower body inwall around steam distributor 3 bases, the outlet of steam input pipe 6 is located at the below of steam distributor 3, and perpendicular to the bottom of steam distributor 3; The external steam separator 7 in tower body 2 tops; Oil plant inlet 1 is located at tower body 2 tops, and the material outlet 5 after the hydrolysis is located at tower body 2 bottoms.Hydrolysis tower design tower internal pressure is 25kg/cm
2
The principle of work of this hydrolysis tower is: oil plant that earlier will hydrolysis mixes with 1/3rd water, enter from cat head, after oil plant has entered, open steam, steam enters at the bottom of tower, be ejected on the bottom surface of steam distributor, scurry out from the space at steam distributor edge then, make oil and water form eddy current, oil fully contacts the back with water hydrolysis reaction takes place, generate lipid acid and glycerine, can make phosphatide and colloid that hydrolysis reaction also takes place simultaneously, generate lipid acid and glycerine.By regulating the valve of steam separator, regulate discharge amount of exhaust gas, the oil plant eddy current in the control hydrolysis tower improves hydrolysis reaction speed.
