Description

Device for separating and recovering saponin and grease in soap grease mixed liquid

Technical Field

The utility model relates to a refined technical field of grease, concretely relates to device of separation, recovery saponin and grease in mixed liquid of soap oil fat.

Background

In recent years, the oil industry has been rapidly developed as the living standard of people increases, during the oil processing, the concentration of a large amount of fatty acid salt and oil-containing alkaline waste water generated by alkali neutralization and water washing processes is high, the pollution is serious, such as direct discharge of the oil, pollution of river water, pollution of clay, microorganism and the like, which refer to suspended substances suspended in water, including inorganic substances, organic substances and silt, clay, microorganism and the like, which are insoluble in water, and the oil is wasted as raw materials for refining and refining, so that the oil is generally used as raw materials for refining and refining of human bodies.

During the refining process of the vegetable oil, a large amount of oil horns and Chinese honeylocust fruits are produced, the content of fat in the oil horns is generally 20-40%, and the total fat content in the Chinese honeylocust fruits can reach 40-50%. Aiming at recycling the oil residue and the saponin, the preparation of mixed fatty acid, oleic acid, stearic acid, epoxy plasticizer and biodiesel is developed at present. The steps of pre-treating the oil residue and the saponin to generate the acidified oil are necessary. In the prior art, the refining method of crude oil mainly comprises a chemical refining method and a physical refining method. The chemical refining process generally comprises a degumming process, an alkali refining process, a decoloring process and a deodorizing (acid) process, wherein the degumming process is usually the first process of crude oil refining and is mainly used for removing hydratable phospholipids and non-hydratable phospholipids contained in the crude oil; the alkali refining process is usually the second process of crude oil refining, and the main purpose of the alkali refining process is to remove redundant acid liquor and free fatty acid in the crude oil in the degumming process, the adopted method is usually to directly add alkali into the degummed oil, the added alkali can react with the free fatty acid and the fatty acid to form saponin, and the saponin is separated and removed before the next process; the decolorization step is usually a third step of crude oil refining, and is mainly intended to remove pigments in the crude oil and also to remove some impurity substances generated in the above steps, such as residual saponin which has not been separated in the neutralization step; the deodorization (acid) step is usually the fourth step of crude oil refining, and is mainly used for separating free fatty acids and odor substances remaining in the decolorized oil and fat from the oil and fat, and the oil and fat obtained after deodorization (acid) is usually refined oil and fat. The deodorization (acid) process mainly adopts a high-temperature gas stripping method: heating the decolorized grease to the evaporation temperature of free fatty acid, distilling the free fatty acid and odor substances remained in the decolorized grease out of the grease under vacuum along with steam stripping, and respectively condensing distillate (steam, free fatty acid and a small amount of fatty acid) in a fractional condensation mode. It is readily apparent from the chemical refining process described above that the caustic refining step and the deodouring (acid) step function similarly in removing free fatty acids. The alkali refining process mainly removes free fatty acid by using the principle of acid-base neutralization reaction, and the deodorization (acid) process removes grease fatty acid by using the principle of evaporation and condensation with different boiling points. In the alkali refining process, alkali liquor is required to be added. However, the crude oil contains both free fatty acids and neutral oils (triglycerides), which are almost simultaneously carried out during the reaction with the alkali solution in the acid-base neutralization reaction, and thus the free fatty acids cannot be effectively removed if the amount of the added base is just equal to the amount of the free fatty acids; if the amount of base added is greater than the amount required for neutralization of the free fatty acids, in addition to reducing the free fatty acid content, this will also result in loss of neutral oil (triglycerides) and additional soapstock waste. Until now, no good solution has been found to solve this problem. The physical refining method is different from the chemical refining method mainly in that the alkali refining process is not performed, and the free fatty acid in the crude oil is extracted mainly by a stripping mode (namely, the final deodorization (acid) process). Physical refining can minimize the loss of neutral oil, and thus, the yield of physical refining is higher than that of chemical refining. However, crude oil with poor quality is generally accompanied with the problem that the color of the oil product is darker, and meanwhile, under the high-temperature steam of physical refining, metal ions, pigments and the like in the crude oil cause the problems of darker color of the refined oil product and shorter shelf life.

In most of the actual production processes, therefore, in order to ensure a relatively high quality of refined oils and fats, chemical refining is often chosen and in order to neutralize the free fatty acids in the crude oil relatively thoroughly, producers often choose to add a quantity of alkali which is much greater than the theoretical quantity of alkali (the excess is generally more than 25%), which, as mentioned above, would result in a serious loss of neutral oil and a large quantity of soapy residue, which increases the solid waste discharge and increases the corresponding disposal costs.

SUMMERY OF THE UTILITY MODEL

The utility model provides an in-process at refined grease that prior art exists, can produce a large amount of honeylocust fruits, and often choose to add the alkali that greatly surpasss the theory and add the alkali volume for the refined grease producer who obtains higher quality, thereby can lead to the serious loss of neutral oil and output a large amount of honeylocust dregs, the problem that solid waste discharged and corresponding treatment cost has been increased is provided, a device for separating in the soap oil fat mixed liquid, retrieve honeylocust fruits and grease, when using, at first add a certain amount of alkali in the crude oil jar and make grease and honeylocust fruit preliminary separation, carry the grease in the crude oil jar to the finished product oil jar after, all the other mixtures of grease and honeylocust fruits are discharged into the treatment tank and are carried out secondary and add the medicine and handle, again with grease and honeylocust fruit separation, can obtain clean grease and clean honeylocust fruits after subsiding, thereby make the honeylocust fruit oil can be used for the production and manufacture field once more, reduces the pollution to the environment and saves the processing cost.
