Description

Technical Field

[0001] The utility model relates to the technical field of deodorization equipment, in particular to a deodorization tower. Background Art

[0002] Deep-sea fish oil is unsaturated fatty acids extracted from deep-sea fish, especially EPA and DHA, while DHA extracted from algae oil has a stronger fishy smell than deep-sea fish oil. In order to reduce the odor of deep-sea fish oil or algae oil, it needs to be deodorized. Deodorization is the process of removing odorous substances by steam distillation under high temperature and high vacuum conditions. Deodorization mainly removes low-level aldehydes, ketones, free fatty acids and unsaturated hydrocarbons by distillation.

[0003] The traditional deodorization process requires the use of a vacuum deodorization tower. During the deodorization process of deep-sea fish oil or algae oil by the traditional deodorization tower, a large number of large-particle impurities enter the deodorization tower, causing the deodorization tower to be affected by impurities when distilling and deodorizing the fish oil, thereby reducing the deodorization efficiency, which is not conducive to enterprise production.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figures 1 to 3 As shown, the deodorizing tower of the utility model comprises: a deodorizing tower body 1, having a primary deodorizing layer 11 and a secondary deodorizing layer 12 which are interconnected, wherein the primary deodorizing layer 11 is located on the upper part of the secondary deodorizing layer 12; wherein, a feed port 2 and a vacuum port 3 are provided on the top of the primary deodorizing layer 11, the primary deodorizing layer 11 is filled with a stainless steel corrugated packing, a discharge port 4 is formed at the bottom of the secondary deodorizing layer 12, a steam injector 5 is arranged in the secondary deodorizing layer 12, and the steam injector 5 is directly facing the bottom of the primary deodorizing layer 11.

[0027] See also Figure 1 The primary deodorization layer 11 is composed of a plurality of filter units connected by bolts. The feed port 2 opened on the top side of the primary deodorization layer 11 is used to inject deep-sea fish oil or algae oil into the primary deodorization layer 11. The vacuum port 3 opened on the top of the primary deodorization layer 11 is used to install a vacuum pump. The vacuum pump can evacuate the first deodorization layer 11 and the secondary deodorization layer 12, and can extract the steam sprayed by the steam ejector 5 to the outside. The steam ejector 5 is connected to the steam generator outside the deodorization tower body 1, and the steam generator can provide steam to the steam ejector 5.

[0028] When deep-sea fish oil or algae oil is deodorized, the oil is first poured into the primary deodorization layer 11 through the feed port 2. The oil moves downward inside the primary deodorization layer 11 under the action of gravity. When the oil passes through the stainless steel corrugated filler, large particle impurities in the oil are screened out by the stainless steel corrugated filler. At the same time, under the action of the steam ejector 5 spraying steam (temperature of 210° C.-240° C.) to the primary deodorization layer 11, low-level aldehydes, ketones, free fatty acids and unsaturated hydrocarbons in the deep-sea fish oil or algae oil are removed under the action of high-temperature water vapor and are pumped out to the outside by the vacuum pump on the top of the primary deodorization layer 11, thereby achieving the purpose of deodorizing and removing impurities from the deep-sea fish oil or algae oil. The structure is simple and the practicability is strong.

[0029] In one or more embodiments, a shield 6 is disposed in the secondary deodorization layer 12 . The shield 6 has a first end and a second end that are oppositely disposed. The first end is used to connect to the bottom of the primary deodorization layer 11 , and the second end surrounds the steam ejector 5 .

[0030] See also Figure 2 The first end of the shield 6 is connected to the bottom of the primary deodorization layer 11, and the second end of the shield 6 extends into the secondary deodorization layer 12 and surrounds the steam injector 5, so that the oil left by the primary deodorization layer 11 can be left through the shield 6. At the same time, the steam injected by the steam injector 5 can be blown to the primary deodorization layer 11 through the shield 6, thereby improving the utilization rate of the steam injected by the steam injector 5 and ensuring the removal efficiency of the odor of deep-sea fish oil or seaweed oil.

[0031] In one or more embodiments, a conical funnel 7 is installed below the steam ejector 5 in the secondary deodorization layer 12 .

[0032] See also Figure 2 The conical funnel 7 is invertedly arranged, so that the deodorized oil flowing down from the primary deodorization layer 11 can be collected centrally, reducing the problem of oil adhering to the inner wall of the secondary deodorization layer 12 and affecting the collection efficiency of the oil.

[0033] In one or more embodiments, the bottom center of the conical funnel 7 extends to the outside of the secondary deodorization layer 12 through the oil guide pipe 8 and connects the secondary deodorization layer 12 with the space below the conical funnel 7. The two pipe openings of the oil guide pipe 8 are staggered in the vertical direction; the outside of the secondary deodorization layer 12 is provided with a ventilation pipe 9 connecting the upper space and the lower space of the conical funnel 7.

[0034] See also Figure 2One end of the oil guide pipe 8 is connected to the bottom of the conical funnel 7, and the other end passes through the outer wall of the secondary deodorization layer 12 and connects the secondary deodorization layer 12 with the space below the bottom of the conical funnel 7; through this arrangement, the oil heated by steam can be cooled faster and the efficiency of oil collection can be improved. The two pipe heads of the oil guide pipe 8 have a certain vertical difference in the height direction, that is, the oil guide pipe is spiral, so that the oil can flow down smoothly.

[0035] See also Figure 2 The ventilation pipe 9 can connect the secondary deodorization layer 12 with the space above and below the conical funnel 7, thereby achieving air pressure balance in the two spaces, making it easier for the oil collected by the conical funnel 7 to flow smoothly into the space below the conical funnel 7 and be collected.

[0036] In one or more embodiments, the baffle 6 is configured in an inverted cone shape.

[0037] See also Figure 2 The inverted cone-shaped shield 6 can effectively collect the steam ejected by the steam ejector 5, thereby maximizing the deodorization of the oil and improving the deodorization efficiency of the oil.

[0038] In one or more embodiments, the shield 6 is made of stainless steel. The shield 6 made of stainless steel can prevent the shield 6 from being corroded and contaminating the oil, thereby ensuring the safety of the oil during deodorization.

[0039] In one or more embodiments, the filling rate of the stainless steel corrugated packing in the primary deodorization layer 11 is 75%-85%. The filling rate of the stainless steel corrugated packing is optional, generally 80%. Through this setting, impurities in the barrier oil can be screened out while ensuring the flow rate of the oil, which is practical.

[0040] In one or more embodiments, a manhole 10 is provided on the lower side wall of the secondary deodorization layer 12. Figure 2 , Figure 3 A valve is provided at the manhole 10, and the manhole 10 is used to manually clean the inside of the secondary deodorization layer 12, so as to facilitate the staff to maintain the deodorization tower.

[0041] In one or more embodiments, the height of the primary deodorization layer 11 is 400-800 mm.

[0042] See also Figure 1 The primary deodorization layer 11 is generally composed of three filter units, each unit is 200 mm high, and the total height is 600 mm.

[0043] In one or more embodiments, a polytetrafluoroethylene coating is sprayed on the inner wall of the secondary deodorization layer 12 and the oil guide tube 8. It should be noted that polytetrafluoroethylene has a certain self-lubricating effect. Spraying the polytetrafluoroethylene coating on the inner wall of the secondary deodorization layer 12 and the inner wall of the oil guide tube 8 can effectively improve the flow efficiency of the oil and reduce the possibility of the oil adhering to the inner wall.

It cannot be used to limit the protection scope of the utility model.
