Description

Technical Field

[0001] The utility model relates to the technical field of crude oil deodorization, in particular to a crude oil deodorization device for refining processing. Background Art

[0002] Crude oil deodorization is a process that utilizes the difference in volatility between odorous substances and triglycerides in oils and fats to remove odorous substances by steam distillation under high temperature and high vacuum conditions. The odorous substances in oils and fats mainly include low molecular aldehydes, ketones, free fatty acids, unsaturated hydrocarbons, etc. Deodorization can not only remove odorous substances in oils, increase the smoke point of oils and fats, improve the flavor of edible oils, but also remove peroxides and their decomposition products. The crude oil deodorization process can cause the unsaturated fatty acids in the oil to undergo isomerization reactions to generate trans fatty acids, which increases the trans fatty acid content in vegetable oils. However, traditional crude oil deodorization equipment either has a processing time that is too long or an oil temperature that is too high. Studies have shown that the higher the oil temperature, the more trans fatty acids increase; the longer the deodorization time, the more trans fatty acids increase.

[0004] The above-mentioned and existing related technologies often have the following defects: when the odor after deodorization is treated, water vapor will be generated, and the water vapor will be directly discharged, which causes waste to a certain extent. At the same time, some harmful gases generated during the water vapor deodorization process are not filtered and treated, and the discharge will cause pollution to the environment.

[0027] Furthermore, the stirring tube is a hollow structure, and a plurality of through holes are opened on the outer wall, and the stirring tube is rotatably connected to the air inlet pipe.

[0028] Through the above technical solution, the air inlet pipe is rotatably connected in the stirring pipe, and water vapor can be directly discharged from the oil, which increases the contact surface with the oil, and the oil and water vapor are mixed faster, making the deodorization time faster.

[0042] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0043] like Figure 1 As shown, the embodiment of the utility model provides a crude oil deodorization device for refining processing, comprising:

[0044] Deodorizing tank 1;

[0045] The oil inlet 2 is fixedly connected to the upper surface of the deodorizing tank 1;

[0046] The oil outlet 3 is fixedly connected to the lower surface of the deodorizing tank 1;

[0047] An air inlet pipe 5 is fixedly connected to the side wall of the deodorizing tank 1;

[0048] An air outlet pipe 6 is fixedly connected to the side wall of the deodorizing tank 1;

[0049] A steam generator 4 is fixedly connected to one end of an air inlet pipe 5;

[0050] The water circulation device 7 is arranged at one end of the gas outlet pipe 6 and is used to filter and condense the gas discharged during the deodorization process to realize water recycling;

[0051] The stirring device 8 is arranged on the inner wall of the deodorizing tank 1 to reduce the deodorizing time of the crude oil.

[0052] like Figures 2 to 4 As shown, the water circulation device 7 includes a condenser 71, which is fixedly connected to the outer wall of the outlet pipe 6, a low-temperature coolant circulation pump 72 is fixedly connected to the lower surface of the condenser 71, a water reservoir 73 is fixedly connected to one end of the outlet pipe 6, and a water outlet 79 is fixedly connected to the side of the water reservoir 73. When water vapor flows through the condenser 71, the coolant repeatedly flowing out of the low-temperature coolant circulation pump 72 will keep the surface of the condenser 71 at a relatively low temperature, and the water vapor will be converted into condensed water when cooled, fall into the water reservoir 73, and finally flow out through the water outlet 79 for collection and reuse.

[0053] like Figure 3 As shown, the inner wall of the air outlet pipe 6 is fixedly connected with an oil baffle plate 74, and the surface of the oil baffle plate 74 is provided with an oil leakage groove 75. When the oil contacts with water vapor, it will splash violently. The oil baffle plate 74 can prevent the oil droplets from entering the air outlet pipe 6 to reduce the loss. The oil leakage groove 75 can make the oil droplets splashed on the oil baffle plate 74 flow back to the deodorizing tank 1.

[0054] like Figure 4 As shown, the inner wall of the water reservoir 73 is provided with a groove 77, and the inner wall of the groove 77 is slidably connected with three filter screens 76, and the filter screens 76 are activated carbon screens. The groove 77 is used to place the filter screens 76, and the activated carbon can remove the substances and organic matter that produce odor in the condensed water, making the condensed water clean and recyclable.

[0055] like Figure 4 As shown, a handle 78 is fixedly connected to the upper surface of the filter screen 76. When the staff replaces the filter screen 76, they only need to pull the handle 78 to remove the filter screen 76, which is convenient for the staff to operate.

[0056] In the embodiment of the utility model (working principle), water vapor flows out from the air outlet pipe 6, first passes through the oil baffle 74 to isolate the mixed splashing oil droplets, then passes through the condenser 71, and is quickly converted into liquid water and flows into the water reservoir 73. After being filtered by the three-layer filter screen 76, it is finally converted into clean water and discharged from the water outlet 79 for collection and reuse. The handle 78 makes it convenient for the staff to replace the filter screen 76, and the replacement operation can be completed quickly.

[0057] like Figure 5As shown, the stirring device 8 includes a motor 81, which is fixedly connected to the bottom of the deodorizing tank 1, and the output end of the motor 81 is fixedly connected to a rotating shaft 82, which is rotatably connected to the inner wall of the deodorizing tank 1, and one end of the rotating shaft 82 is fixedly connected to a stirring tube 83. The operation of the motor 81 drives the rotating shaft 82 to rotate, and the stirring tube 83 fixed to the rotating shaft 82 rotates accordingly, driving the oil at the bottom of the deodorizing tank 1 to turn over to the surface, so that the oil quickly heats up and reacts with water vapor.

[0058] like Figure 5 As shown, the stirring tube 83 is a hollow structure, and a plurality of through holes are opened on the outer wall, and the stirring tube 83 is rotatably connected with the air inlet pipe 5. Water vapor is discharged from the through holes on the stirring tube 83, and is in close contact with the oil, and the stirring tube 83 is constantly rotating, which greatly reduces the deodorization time.

[0059] like Figure 5 As shown, the inner wall of the air intake pipe 5 is fixedly connected with a fixing block 84, the lower surface of the fixing block 84 is fixedly connected with a spring 85, one end of the spring 85 is fixedly connected with an oil blocking boss 87, and the inner wall of the air intake pipe 5 is fixedly connected with a limiting block 86, and the limiting block 86 is sleeved on the surface of the spring 85. When water vapor is discharged downward from the air intake pipe 5 under pressure, the oil blocking boss 87 and the limiting block 86 are in a separated state and can flow out normally. When the deodorization is completed and the water vapor supply is stopped, the oil blocking boss 87 and the limiting block 86 are combined together under the force of the spring 85 to prevent oil from flowing back into the air intake pipe 5.

[0060] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
