Description
Technical field
The present invention relates to oil and fat refining fields, a kind of grease essence being especially dehydrated from the grease after alkali refining, washing
Dewatering during refining.
Background technique
Currently, oil and fat refining includes physical refining and two kinds of chemical refining.Wherein, chemical refining includes alkali-refining deacidification, water
Alkali, dehydration, decoloration, deodorization etc. are washed away, dehydration is essential in oil chemistry refining process.It mainly uses at present with lower section
Method：
By after alkali refining, washing grease injection sealing heating tank in, be heated to 95~100 DEG C, be evacuated to -0.09mPa with
Above, under the conditions of being stirred continuously, continue 3.5 hours or more, moisture is made constantly to volatilize to reach dehydration purpose（Standard provides moisture content
Not higher than 0.10%）.But the problem as present on method, dewatering time is long, and energy consumption is high, and at high cost, production efficiency is low, and protects
Product quality is not demonstrate,proved, therefore improvement on dewatering and innovation are imperative.
Summary of the invention
For above situation, for the defect for overcoming the prior art, it is an object of the present invention to provide a kind of oil and fat refining process
In dewatering, can effectively solve it is energy saving, reduce production cost, shorten the production cycle, improve the quality problems of grease.
The technical solution that the present invention solves is, the dewatering in a kind of oil and fat refining process is：It at room temperature, will be aqueous
Grease has fluid hole, lays flat the partition with filter opening above tubulation from the tubulation that dehydration lower box part is sent into bottom on tubulation, every
Plate has been placed above salt layer, aqueous grease by the salt layer on partition and partition constantly to top dewatering box output flow,
Moisture in aqueous grease becomes common salt aqueous solution by salt absorption, since the specific gravity of common salt aqueous solution is greater than grease, saline solution
Solution constantly flows downward, and grease constantly flows up, and makes water-oil separating, and dewatered grease goes out through being dehydrated the grease of upper box part
Mouth is sent into bleacher, and common salt aqueous solution collects discharge in dehydration lower box part, for the water scouring water after alkali refining, economizes on resources, subtract
Few pollution to environment.
The method of the present invention is simple, easy to operate, high production efficiency, and dehydrating effect is good, and energy-saving and environmental protection, it is economical and
Social benefit is huge.
Detailed description of the invention
Fig. 1 is the structural front view of present device.
Fig. 2 is the sectional front view of present device.
Specific embodiment
Below in conjunction with concrete condition, elaborate to a specific embodiment of the invention.
In specific implementation, the dewatering in a kind of oil and fat refining process is the present invention, at room temperature, will with liquid pump
Aqueous grease is placed in the tubulation that laterally there is gap in dewatering box bottom from bottom side feeding, and upward liquid out is evenly equipped on tubulation
Hole is laid flat above tubulation equipped with the partition with filter opening, and the food at least occupying tank-volumes 9/10 is placed in cabinet above partition
Salt, constitutes the salt layer that top is plane, and aqueous grease is constantly gone out to top dewatering box by the salt layer on partition and partition
Mouthful flowing, for aqueous grease during coming into full contact with salt, it is water-soluble that moisture in aqueous grease by salt absorption becomes salt
Liquid, since the specific gravity of common salt aqueous solution is greater than grease, common salt aqueous solution constantly flows downward, and grease constantly flows up, thus
Making water-oil separating, water content≤0.03% of grease, the grease outlets that dewatered grease is dehydrated upper box part are sent into bleacher,
Common salt aqueous solution collects in dehydration lower box part, and the sewage draining exit for being periodically dehydrated lower box part, which is discharged, to be collected, for the washing after alkali refining
It with water, economizes on resources, reduces the pollution to environment.
The dewatering box includes the sealing cover 2 on cabinet 1 and cabinet top, is provided with sewage draining exit 3, cabinet among the bottom of box
Bottom is equipped with horizontal tubulation 4, has uniformly upward fluid hole on tubulation 4, the level being closely packed together is placed above in tubulation 4
Partition 5 is evenly equipped with the through-hole communicated with fluid hole on horizontal baffle（It is not indicated in figure）, cabinet side is equipped with to be connected with tubulation
Aqueous grease inlet tube 6, have grease outlets pipe 7 in the middle part of sealing cover 2, be opened in sealing cover on alternate with grease outlets pipe 7 is provided with
Mouth 10, the salt layer filled with the plane at least accounting for tank-volumes 9/10 above horizontal baffle is added in salt with helixseal lid
8, aqueous grease enters tubulation, sprays to horizontal baffle again through fluid hole, enters salt layer through through-hole uniformly distributed on horizontal baffle, food
Salt deposit after the moisture absorption in aqueous grease, will flow down through tubulation gap, flows into dewatering box bottom, is discharged by sewage draining exit；
The bottom of box of the dewatering box is in downward inclined plane shape, and sewage draining exit 3 is opened in the lowest point at bottom of box center, with benefit
In the discharge of common salt aqueous solution；
The sealing cover 2 is in upward inclined plane shape, and grease outlets pipe 7 is opened in the highest point at sealing cover center, in favor of grease
Discharge；
First valve 9-1 is housed on the grease outlets pipe 7, second valve 9-2, aqueous grease import are housed on sewage draining exit 3
On pipe 6 be equipped with third valve 9-3, be respectively used to control grease outlets pipe 7, sewage draining exit 3, aqueous grease inlet tube 6 unlatching or
It closes.
From the above, it is seen that the present invention be by aqueous grease under the action of liquid pump, by aqueous grease through tubulation and
Horizontal baffle is pumped into dedicated dehydration equipment（Dewatering box）In come into full contact with salt, the moisture in grease by salt absorption become
Aqueous solution just constantly flows downward since common salt aqueous solution specific gravity is greater than grease, and grease constantly flows up, and makes water-oil separating,
Reach the purpose of grease dehydration.
Through on probation, the method for the present invention small investment energy saving 1 times or more, reduces life due to being not required to heating and vacuum condition
Produce 50% or more cost；Since this process carries out during being transferred to decoloration oil tank from the oil tank after washing, eliminate heated
Journey, shortens the production cycle, and production efficiency improves 2 times or more；Since this process is not required to heat, can effectively prevent in the process
The lost or generation chemical change of fractions, greatly reduces the pollution to environment；The salt water generated during this can make alkali
Oily washing is used after refining, does not increase new pollution sources, will not generate secondary pollution, is energy-saving and environment friendly, economy and society
It can Benefit.
