Description
Technical Field
The invention relates to the technical field of grease storage, in particular to a storage system for quickly precipitating crude oil residue of grease.
Background
The oil residue generally refers to the sediment of the vegetable oil crude oil after hydration or long-term standing. Taking soybean oil as an example, the main components of soybean oil residue are phospholipid, neutral oil, water and other lipid substances, and in addition, the soybean oil residue also contains a small amount of protein, saccharide, wax, pigment and organic and inorganic impurities, and the components can be aggregated together in the storage and standing process of the soybean oil to form a colloid precipitate substance with higher viscosity, which is commonly called as oil residue.
Ultrasonic waves are sound waves with a frequency higher than 20000 hertz, which are directional, have high penetration capacity, easily obtain concentrated sound energy, can propagate in various media and can propagate for a sufficiently long distance. When standing waves are formed in an ultrasonic fluid medium, tiny particles suspended in the fluid are aggregated at nodes under the action of mechanical force, and form periodic accumulation in space.
At present, a large grease storage tank is adopted for grease storage in China, the storage of crude vegetable oil is mainly used, particularly, the crude soybean oil and the crude rapeseed oil are abundant, most of oil residues in the crude oil can naturally precipitate to the bottom of an oil tank in the long-term storage process, a small amount of oil residues are adhered to the wall of the oil tank, phospholipid in the oil residues has certain hydrophilicity, so that water in the crude oil is easily combined with the oil residues in the storage process, free fatty acid is adsorbed and gathered in the oil residues along with the prolonging of time, a water layer with high acidity appears at the bottom of the oil tank, the rancidity of the grease is caused, the quality of the grease is influenced, and the storage stability is reduced. Meanwhile, the corrosion of the oil tank can be accelerated, and the tank wall becomes thin and even leaks.
In addition, the standing and precipitating oil storage tank can form stable oil foot layering after a period of time, when new oil is injected subsequently, the oil foot can float upwards in the oil tank due to disturbance, so that the oil foot is redistributed in the tank body, and a plurality of reaction centers are formed by the oil foot, so that the quality of the new oil is reduced, and the rancidity of the oil is accelerated.
In the actual production process, the oil residue of the physically squeezed oil needs to be removed and then filtered and filled, and the oil residue settling velocity is low, so that the occupied time of the tank volume is long, and the situation that the oil tank is not economical in use also happens occasionally.
The patent specification with the publication number of CN202822887U discloses a rapeseed oil refining settling tank, which comprises an upper cylindrical tank body and a lower conical tank body, wherein a tee joint is welded on the lower edge of the cylindrical tank body, the upper end of the tee joint is communicated with an oil inlet pipe through a first control valve, the lower end of the tee joint is communicated with an oil outlet pipe through a second control valve, the side end of the tee joint is communicated with the cylindrical tank body, and the lower end of the conical tank body is provided with a slag discharge port and a third control valve. According to the scheme, through the operation of the first control valve, the second control valve and the third control valve, the working procedures of oil inlet, oil outlet, oil foot discharge and the like can be completed quickly, but the problem of slow natural settling speed of the oil foot still exists in the scheme.
Disclosure of Invention
The oil residue settling speed is low in the actual production process of the oil, the subsequent production and processing are influenced, the processing period is prolonged, in addition, the storage tank cannot be rotated in time, and further the problem that the oil tank is not economical is caused, and the problem that the oil residue naturally settles at a low speed in the oil storage process, and cannot be drawn out of the tank body in time, and the oil storage quality is influenced are solved. The invention provides a storage system for accelerating the sedimentation of oil residue and cleaning the sedimented oil residue out of an oil tank in time.

After standing and settling for several days, after the oil residue of the grease settles stably, the oil residue is enriched in the guide plate 301 and gradually collected to the collecting tank 302, and flows into the oil residue inlet pipe 401 through the screen 305, at the moment, the inlet pipe valve 402 is opened, the screw pump motor 405 installed on the pump body bracket 403 is started, and the oil residue deposited at the bottom of the oil storage tank is pumped out through the oil residue outlet pipe 406 by the screw pump 404.
Particularly, in cold winter, the heating plate 303 installed inside the oil foot collecting tank 302 can be used, the heating power supply 304 is started to heat the oil foot to reduce the viscosity of the oil foot, the fluidity of the oil foot is enhanced, the oil foot is conveniently pumped out by the screw pump 404, in addition, when the oil foot is not smoothly pumped out by the screw pump 404, the screen 305 may be blocked, at the moment, compressed gas can be introduced into the aeration device 306 through the compressed gas source 307, aeration treatment is carried out, blockage is dredged, and smooth pumping out of the oil foot is facilitated.
Compared with the traditional natural precipitated oil sludge, the storage system of the invention is subjected to experiment, and the experimental oil adopts the traditional pressed crude peanut oil. The storage system is ultrasonically treated into a test group, a control group adopts a natural sedimentation mode, 3 test groups and 1 control group are arranged, and the same container and the same placing environment are adopted. Specific processing parameters, processing 1: 300W 7min, treatment 2: 400W 7min, treatment 3: 500W 3 min.
As shown in FIG. 4, phospholipid is used as the oil foot marking substance, and the oil foot precipitation condition is reflected by continuous observation of the content of phospholipid in the oil foot precipitation process of crude oil. And by combining sensory evaluation, under the conditions of ultrasound with proper power and treatment time, the settling speed of the crude oil treatment group is higher than that of the control group, the control group basically and completely settles in 14 d-16 d, the treatment group basically and completely settles in 10 d-12 d, and the grease is more transparent and clearer.
As shown in figures 5 and 6, through monitoring the key indexes of oil, namely acid value and peroxide value, the ultrasonic-treated crude peanut oil is beneficial to oil residue precipitation, does not influence basic physicochemical indexes, and does not influence the storage and edible quality of the oil.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
