Description

Soda acid time delay reaction accurate-adjusting equipment

Technical field

The utility model relates to oil refining plant technical field, especially a kind of soda acid time delay reaction accurate-adjusting equipment.

Background technology

In oil refining process, will remove the impurity outside tri-glyceride, containing the impurity such as some amount non-hydratable phospholipid, free fatty acids, pigment, wax and calcium, magnesium, iron trace metal in oil, the removal of these impurity is then comparatively difficult as far as possible.And traditional equipment is too extensive, at the poor crude oil of refined quality, (non-hydratable phospholipid content is more, batch acid value difference), refining loss is difficult to control especially, come unstuck with on alkali-refining deacidification basis in traditional acidifying, should adjusting process parameter in time to different glyceride stock, to come unstuck to improve, deacidification effect (after making fat degumming, phospholipids content is less than 5ppm ~ below 10ppm, and free fatty acids amount is less than 0.1%).Depickling, dealkalize time delay conversion unit are that manufacturing factory makes by processing parameter, can reach processing requirement when satisfied setting production conditions.But irreversible loss can be caused during working condition change, as:

1. phosphoric acid add after the reaction times be less than the process time, non-hydratable phospholipid conversion not exclusively, causes phospholipids content to exceed standard, cause refining to be difficult to carry out or product defective.After phosphoric acid adds, the reaction times is greater than the process time, can solidify oil product color, makes pigment be difficult to deviate from bleaching workshop section and increase refining cost.

2. alkali lye add after the reaction times be less than the process time, neat soap is broken littlely can not effectively flocculate and adsorb, increase separating difficulty and refining cost.Reaction times, when being greater than the process time, Chinese honey locust flocculation neat soap was than great, and can not form mutually balanced and be deposited in device bottom, time serious, blocking pipe causes producing interruption.

In the acid adding dephosphorization of edible oil, alkali lye and technique: be reduce the non-hydratable phospholipid content in oil product, be beneficial to refining one-level oil product deodorization workshop section technique to carry out smoothly, so crude oil is heated to 60 ~ 75 DEG C, then squeeze into food grade 85% phosphoric acid (accounting for 0.05 ~ 0.2% of oil mass) by sour pump of constant delivery type, enter acid-respons tank time delay reaction after short mix and (1. transfer non-hydratable phospholipid to hydrated phospholipid after reaction; 2. make chlorophyll transform the shallow phoeophytin of quality, also effective to reduction redness; 3. complexation of metal ions, the trace metal such as passivated iron, copper is to the katalysis reducing Oxidation of Fat and Oils; ).

For deviating from the free fatty acid content in oil product, with adding in food grade sodium hydroxide solution and free fatty acids and generating soap in suitability for industrialized production, generally by oil product temperature adjustment about 60 ~ 75 DEG C, then (neat soap adsorbs the impurity such as colloid, pigment in thick oil to enter alkali reaction tank time delay reaction after the food grade sodium hydroxide solution short mix squeezed into by alkali pump of constant delivery type, and under ionogen, temperature and stirring action, attract each other and flocculate into large Chinese honey locust micelle, neutral oil extruding in being rolled into a ball by soap is discharged, and is beneficial to whizzer and is separated and improves yield).

The equipment adopted: ortho acid, alkali time delay conversion unit are made up of annexes such as retort, stirring wing, oil-in, oil pumping mouths, from the continuous oil-feed of top oil-in of retort, oil product is extracted out continuously from oil pumping mouth, the volume of retort, oil-in and oil outlet are all changeless, so the raw material reaction time cannot adjust.
