Description

The quick deacidification device of a kind of high-acid value grease
Technical field
The utility model relates to the quick deacidification device of a kind of grease, and the particularly quick deacidification device of a kind of high-acid value grease belongs to the chemical industry equipment field.
Background technology
Acid number is one of important indicator of reflection animal-plant oil quality, and acid number surpasses certain limit and means that grease is not suitable for eating, and is called high-acid value grease, (mainly contains: the waste grease after fried food as discarded food oils; The grease that the food and drink water drain reclaims, namely what is often called sewer oil or tear oil), the long-term deposit of grease surpasses the rotten grease of quality guaranteed period acidifying and reclaim the grease that obtains etc. from the various oil foot of edible oil factory and all possess this feature.High-acid value grease atmosphere pollution and environment are often come into the market after processing through simple decolouring, deodorization, depickling again by illegal retailer, owing to containing a large amount of germs and carcinogenic substance, public health are caused very big harm.Yet, for the preparation of biofuel, be but the resource of high-quality with these high-acid value greases.At present, need to carry out esterification acid reduction when utilizing preparing biological diesel fuel by high-acid-value grease processes, esterification is reversible reaction, generally reaction is carried out not thorough, according to reaction equilibrium theory, improve transformation efficiency, need to separate a kind of composition from resultant or make in reactant a kind of excessive method of composition that the reaction positive dirction is carried out.If the water that esterification is generated removes or provide excessive methyl alcohol that reaction is carried out to the direction that generates ester timely, therefore, the water that how above esterification is generated in time removes, and is significant to realizing the quick esterification acid reduction of high-acid value grease.
Summary of the invention
The utility model purpose is to provide the quick deacidification device of high-acid value grease that a kind of speed of response is fast, transformation efficiency is high.
The technical solution of the utility model is: the quick deacidification device of high-acid value grease comprises esterifier 1, prolong 2, molecular sieve packed column 3, an acidic catalyst head tank 4, methanol feedstock tank 5 and glyceride stock tank 6; Esterifier 1 is connected with molecular sieve packed column 3 by prolong 2, the bottom of molecular sieve packed column 3 is connected to the bottom of esterifier 1 by pipeline, an acidic catalyst hold-up vessel 4, methanol feedstock hold-up vessel 5 and high-acid value grease raw material storage tanks are connected and are connected with esterifier 1.
Prolong described in the utility model 2 is cylindrical tubulation structure, and the lower end is connected with molecular sieve packed column 3 by pipeline, and methanol steam and water vapor enter the top of prolong 2 from pipeline, is condensed into liquid state through prolong 2 and enters into molecular sieve packed column 3.
Molecular sieve packed column 3 described in the utility model is one to be filled with the right cylinder of molecular sieve, and its upper end joins by conduit and condenser 2, and the lower end is passed into the bottom of esterifier 1 by pipeline; Methanol steam and water vapor are liquefied as liquid methanol and water under the effect of prolong 2, during by molecular sieve packed column 3, with moisture absorption, remaining liquid methanol is got back to sustainable participation esterification in esterifier 1 through pipeline.
working process of the present utility model and principle are: according to proportioning raw materials, respectively with the catalyzer in an acidic catalyst hold-up vessel 4, methyl alcohol in methanol feedstock hold-up vessel 5, high-acid value grease in high-acid value grease head tank 6 is added in esterifier 1, start simultaneously condenser 2 and esterifier 1 is heated, glyceride stock and methyl alcohol carry out esterification under the effect of an acidic catalyst, the water that excessive methyl alcohol and esterification generate with the steam form from esterifier 1 out, arrive the top of prolong 2 by pipeline, the liquefaction of methanol vapor and water vapour is liquid first alcohol and water under the effect of prolong 2, enter into molecular sieve packed column 3, molecular sieve absorbs water, methyl alcohol is got back to sustainable participation esterification in esterifier 1 through pipeline, thereby the water of having realized one of product of producing in esterification is constantly shifted out esterifier, reached the quick deacidification purpose of high-acid value grease.
The utility model is taken with the form of gaseous state the water that esterification generates out of with methanol steam, and be condensed into liquid water, during by molecular sieve packed column with moisture absorption, this reversible reaction is carried out to the direction that generates ester, reach the purpose of the quick deacidification of high-acid value grease, liquid methanol is got back to sustainable participation reaction in esterifier, has realized the cycling and reutilization of methyl alcohol; High-acid value grease becomes the raw material that is fit to this glass biofuel through deacidification, that this device has is simple in structure, efficient is high, low power consumption and other advantages.
