[0026] like Figure 1-3 As shown, this embodiment provides a deodorizing distillate analysis system, including a fatty acid trap 11, a analyzing device, a first capturing device, a second capturing device and a vacuum device, wherein the output end of the fatty acid trap 11 is connected to the input end of the analyzing device through a pipeline, the output end of the analyzing device is connected to the input ends of the first capturing device and the second capturing device through pipelines, respectively, and the vacuum device is connected to the output ends of the first capturing device and the second capturing device, respectively.

[0027] Specifically, the bottom of the side of the fatty acid trap 11 is connected to the oil refining workshop through the feed pipe 12, and the deodorized distillate after the refinement is input into the interior of the fatty acid trap 11; the top of the fatty acid trap 11 is connected to a vacuum pipe 16, and the vacuum pipe 16 is connected to a vacuum device, and the vacuum device is used to evacuate the interior of the fatty acid trap 11 to ensure that the vacuum state is maintained; the side of the fatty acid trap 11 is connected to a fatty acid circulation pipe 13, and the two ends of the fatty acid circulation pipe 13 are respectively connected to the upper and bottom ends of the fatty acid trap 11; the fatty acid circulation pipe 13 is provided with a fatty acid circulation pump 14 and a plate cooler 15; the fatty acid circulation pipe 13 is located between the fatty acid circulation pump 14 and the plate cooler 15 and is connected to the parsing tower 21 through a pipe; an outdoor fatty acid tank 17 is connected between the fatty acid circulation pipe 13 and the parsing tower 21.

[0028] In this embodiment, the deodorized distillate from the refining workshop is transported into the fatty acid trap 11 through a pipeline, and the deodorized distillate inside the fatty acid trap 11 is continuously circulated and cooled in the plate cooler 15 and the fatty acid trap 11 by the fatty acid circulation pump 14, and then transported to the desorption tower 21 through a pipeline. During the capture process, vacuum is drawn through the vacuum pipe 16 to maintain the internal vacuum state, and if the desorption tower 21 does not work during the circulation process, the raw materials can be first transported to the outdoor fatty acid tank 17 for storage.

[0029] Specifically, the analysis device includes a analysis tower 21, the input end of the analysis tower 21 is connected to the fatty acid collector 11, and the output end of the analysis tower 21 is respectively connected to the input ends of the first capturing device and the second capturing device, and the side of the analysis tower 21 is connected to a analysis circulation pipe 22 through a pipe, and the two ends of the analysis circulation pipe 22 are respectively connected to the upper and bottom ends of the analysis tower 21, and the analysis circulation pipe 22 is provided with a analysis circulation pump 24 and a mass stabilizer 23. The mass stabilizer 23 in this embodiment is a heating device in the prior art, which increases the temperature of the raw materials by the heating device and controls it within a certain range. The side of the analysis circulation pipe 22 is connected to a crude oil tank 25.

[0030] Furthermore, the desorption circulation pipe 22 is connected to a desorption heat exchanger 26 and a cooler 27 .

[0031] Furthermore, a steam pipe 28 is provided at the bottom of the desorption tower 21. The steam pipe 28 has a steam hole. One end of the steam pipe 28 passes through the desorption tower 21 and is connected to a steam device. Steam is input through the steam device and enters the desorption tower 21 through the steam pipe 28 to increase the temperature of the raw materials.

[0032] In this embodiment, after the raw material enters the analytical tower 21, the raw material is circulated in the analytical tower 21 and the analytical circulation pipeline 22 by the analytical circulation pump 24. The raw material enters the analytical circulation pipeline 22 from the upper part of the analytical tower 21 through the action of the analytical circulation pump 24, and then enters the mass stabilizer 23 after heat exchange through the analytical heat exchanger 26, is heated by the mass stabilizer 23, and finally returns to the analytical tower 21 to achieve circulating heating. After two temperature rise and parsing, the remaining neutral oil enters the return crude oil tank 25 for storage after cooling. When cooling, the valve connected to the analytical heat exchanger 26 is first closed, and then the valve of the cooler 27 is opened. At this time, through the action of the analytical circulation pump 24, the raw material enters the analytical circulation pipeline 22 from the analytical tower 21, passes through the cooler 27 and finally returns to the analytical tower 21. After the cooling is completed, the valve of the cooler 27 is closed, the valve of the return crude oil tank 25 is opened, and the cooled neutral oil is input into the return crude oil tank 25.

[0033] Specifically, the first capturing device includes a first capturing tower 31, the input end of the first capturing tower 31 is connected to the output end of the decomposition tower 21 through a pipeline, a first valve 32 is provided between the first capturing tower 31 and the decomposition tower 21, a first circulation pipeline 33 is connected to the side of the first capturing tower 31, a first circulation pump 34 and a first heat exchanger 35 are provided on the first circulation pipeline 33, the top end of the first circulation pipeline 33 is provided at the upper part of the interior of the first capturing tower 31, the top end of the first circulation pipeline 33 is connected to the first spray head 331, a first wire mesh demister 311 is provided above the interior of the first capturing tower 31, and a first filler 312 is provided below the first capturing tower 31.

[0034] In this embodiment, when the raw material is parsed by the parsing tower 21, the temperature of the parsing tower 21 rises to about 160°C. At this time, the first valve 32 is opened, and the vacuum device connected to the first capture tower 31 is evacuated to absorb the parsed high-purity fatty acids into the first capture tower 31. The contact area of the material is increased by the first filler 312 to improve the capture effect. The captured high-purity fatty acids enter the first circulation pipeline 33 through the first circulation pump 34, and then re-enter the first capture tower 31 after cooling through the first heat exchanger 35. The capture effect is achieved through continuous circulation cooling. When the liquid level of the parsing tower 21 no longer decreases, it is switched to the second capture device. At this time, the first valve 32 is closed, and the air extracted by the vacuum device is filtered and removed after passing through the first wire mesh demister 311.

[0035] Specifically, the second capturing device includes a second capturing tower 41, the input end of the second capturing tower 41 is connected to the output end of the decomposition tower 21 through a pipeline, a second valve 42 is provided between the second capturing tower 41 and the decomposition tower 21, a second circulation pipeline 43 is connected to the side of the second capturing tower 41, a second circulation pump 44 and a second heat exchanger 45 are provided on the second circulation pipeline 43, the top end of the second circulation pipeline 43 is provided at the upper part of the interior of the second capturing tower 41, the top end of the second circulation pipeline 43 is connected to a second spray head 431, a second wire mesh demister 411 is provided above the interior of the second capturing tower 41, and a second packing 412 is provided below the second capturing tower 41.

[0036] In this embodiment, after the first capture device is captured, the first valve 32 is closed, and the temperature of the parsing tower 21 is raised to about 260°C. The second valve 42 is opened, and the vacuum device connected to the second capture tower 41 is evacuated, and the high-VE fatty acid after parsing is sucked into the second capture tower 41. The contact area of the material is increased by the second filler 412 to improve the capture effect. The captured high-VE fatty acid enters the second circulation pipeline 43 through the second circulation pump 44, and then re-enters the second capture tower 41 after being cooled by the second heat exchanger 45. By continuous circulation cooling, the capture effect is achieved. When the liquid level of the parsing tower 21 no longer decreases, the second valve 42 is closed, and the air extracted by the vacuum device is filtered and removed after being removed by the second wire mesh demister 411.

[0037] Specifically, the vacuum device includes a vacuum pump 51, which is connected to the first and second capture devices via pipes. A capture condenser 52 is provided between the vacuum pump 51 and the first and second capture devices. The bottom of the capture condenser 52 is connected to a sealed tank 53 via a pipe. The vacuum pump 51 creates a vacuum, and the extracted high-temperature gas is condensed in the capture condenser 52 before being withdrawn. The condensed water is stored in the sealed tank 53.

[0038] The working principle of the utility model is as follows: the deodorized distillate from the refining workshop is transported into the fatty acid trap 11 through a pipeline, the deodorized distillate inside the fatty acid trap 11 is continuously circulated and cooled in the plate cooler 15 and the fatty acid trap 11 by the fatty acid circulation pump 14, and then transported to the desorption tower 21 through a pipeline. During the collection process, vacuum is drawn through the vacuum pipe 16 to maintain the internal vacuum state, and if the desorption tower 21 does not work during the circulation process, the raw material can be first transported to the outdoor fatty acid tank 17 for storage;

[0039] After the raw material enters the analysis tower 21, the raw material is circulated in the analysis tower 21 and the analysis circulation pipe 22 by the analysis circulation pump 24. The raw material enters the analysis circulation pipe 22 from the upper part of the analysis tower 21 through the action of the analysis circulation pump 24, and then enters the mass stabilizer 23 after heat exchange through the analysis heat exchanger 26. The temperature is increased by the mass stabilizer 23 and finally returns to the analysis tower 21 to achieve circulation heating. When the temperature in the analysis tower 21 rises to 160°C, the first valve 32 is opened, and the vacuum device connected to the first capture tower 31 is used to evacuate the air, and the analyzed high-purity fatty acids are sucked into the first capture tower 31. The contact area of the material is increased by the first filler 312 to improve the capture effect. The captured high-purity fatty acids enter the first circulation pipe 33 through the first circulation pump 34, and then cool down through the first heat exchanger 35 and re-enter the first capture tower 31. The capture effect is achieved through continuous circulation cooling. When the liquid level of the analysis tower 21 stops decreasing, the second capture device is switched. At this time, the first valve 32 is closed, and the air extracted by the vacuum device is filtered through the first wire mesh demister 311 and then extracted. At this time, high-purity fatty acids are captured in the first capture tower 31.

[0040] After closing the first valve 32, the temperature of the capture tower is continued to be increased. When the capture tower temperature reaches 260°C, the second valve 42 is opened and the vacuum device connected to the second capture tower 41 is evacuated. The high-VE fatty acid after parsing is sucked into the second capture tower 41. The contact area of the material is increased by the second filler 412 to improve the capture effect. The captured high-VE fatty acid enters the second circulation pipeline 43 through the second circulation pump 44, and then re-enters the second capture tower 41 after being cooled by the second heat exchanger 45. By continuous circulation cooling, the capture effect is achieved. When the liquid level of the parsing tower 21 no longer decreases, the second valve 42 is closed, and the air extracted by the vacuum device is filtered and removed after being filtered by the second wire mesh demister 411. At this time, what is captured in the second capture tower 41 is the high-VE fatty acid.

[0041] After two rounds of capture, what remains in the analytical tower 21 is neutral oil with a high sterol concentration. After cooling, the neutral oil enters the return crude oil tank 25 for storage. When cooling, first close the valve connected to the analytical heat exchanger 26, and then open the valve of the cooler 27. At this time, through the action of the analytical circulation pump 24, the raw material enters the analytical circulation pipeline 22 from the analytical tower 21, passes through the cooler 27 and finally returns to the analytical tower 21. After cooling is completed, close the valve of the cooler 27, open the valve of the return crude oil tank 25, and input the cooled neutral oil into the return crude oil tank 25.

[0042] This system can increase the VE concentration to over 9% and produce pure fatty acids and neutral oils; it greatly increases the value of by-products and improves the yield of finished products.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them.
