Description

Technical Field

[0001] This utility model relates to the field of biodiesel processing technology, and in particular to a biodiesel pre-fraction decolorization and deodorization device. Background Technology

[0002] As a renewable and clean energy source, the pre-fraction treatment in the production process of biodiesel is crucial. Effective decolorization and deodorization of the pre-fraction are key steps in improving product quality during biodiesel production. In practical applications, biodiesel pre-fraction decolorization and deodorization equipment typically requires the following technologies:

[0003] 1. Decolorization mechanism, such as using activated carbon adsorption, chemical oxidation and other methods, to remove pigment substances in the fore fraction;

[0004] 2. Odor removal mechanisms, such as vacuum degassing and gas adsorption, reduce odor components in the pre-distillate;

[0005] 3. Separation mechanisms, such as membrane filtration and centrifugal separation, enable the separation of decolorizing and deodorizing agents from the pre-distillate.

[0006] Existing Chinese patent: A decolorization and deodorization device for biodiesel pre-fraction, patent number: CN213995359U, its structure includes a base plate, a distillation tank, a decolorization and deodorization mechanism, an infusion pipe, support legs, a power cord, and a controller. This utility model's decolorization and deodorization device for biodiesel pre-fraction, by setting up a decolorization and deodorization mechanism, allows the high-speed rotating blades to drive rapid airflow when gas from distillation enters the mechanism. During rotation, the deodorizer also works to quickly adsorb odors. This solves the problems of existing decolorization and deodorization devices for biodiesel pre-fraction having a simple structure, limited performance, low efficiency during distillation, slow heating, slow distillation, and slow outflow, and not particularly significant deodorization effect.

[0007] However, during the implementation of the above technical solution, at least the following technical problems were found: the above decolorization and deodorization equipment removes odors by rotating the deodorizer, and the distilled gas is difficult to fully contact the deodorizer, so it is difficult to achieve sufficient decolorization and deodorization. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a biodiesel pre-fraction decolorization and deodorization device, which solves the technical problem that the aforementioned decolorization and deodorization devices use a rotating deodorizer for deodorization, making it difficult for the distilled gas to fully contact the deodorizer and thus achieve sufficient decolorization and deodorization.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A biodiesel pre-fraction decolorization and deodorization device includes a base, a decolorization and deodorization tank fixedly mounted on the base, an air pump fixedly mounted on the base, an air guide pipe installed between the decolorization and deodorization tank and the air pump, a liquid guide pipe installed inside the base, an oil pump fixedly mounted at the end of the liquid guide pipe, a first solenoid valve fixedly mounted at the end of the liquid guide pipe, a second solenoid valve fixedly mounted at the end of the liquid guide pipe, a stainless steel filter plate fixedly mounted inside the decolorization and deodorization tank, a decolorization layer for diesel decolorization fixedly mounted on the stainless steel filter plate, and a deodorization layer for diesel deodorization fixedly mounted on the decolorization layer. The stainless steel filter plate divides the decolorization and deodorization tank into upper and lower chambers. The first solenoid valve is located inside the decolorization and deodorization tank, and the second solenoid valve is located outside the decolorization and deodorization tank. The decolorization and deodorization tank has an air inlet and an oil inlet.

[0011] Preferably, the bottom of the decolorizing and deodorizing barrel is threaded with a stopcock; after unscrewing the stopcock, the inside of the decolorizing and deodorizing barrel can be cleaned.

[0012] Preferably, a first filter cartridge for intercepting small particulate impurities is fixedly installed on the stopcock, and the mesh diameter of the stopcock is smaller than that of the stainless steel filter plate.

[0013] Preferably, a sealing gasket is fixedly installed on the stopcock to seal the decolorizing and deodorizing barrel, ensuring that no leakage occurs when the internal pressure of the decolorizing and deodorizing barrel increases.

[0014] Preferably, both the air inlet and the oil inlet are equipped with sliding sealing plugs.

[0015] Preferably, a spring is installed below the sealing plug; the sealing plug will block the air inlet and oil inlet under the action of the spring force.

[0016] Preferably, a second filter cartridge for filtering external impurities is installed inside the oil inlet.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. After diesel fuel enters the decolorizing and deodorizing barrel, it remains in the upper half. Then, under the influence of gravity, the diesel fuel slowly seeps into the lower half of the barrel. During this process, the decolorizing layer adsorbs pigments and other substances in the passing diesel fuel, and the deodorizing layer adsorbs odors. The stainless steel filter plate allows the diesel fuel to pass through while preventing the decolorizing and deodorizing layers from falling to the bottom of the barrel, thus completing the decolorization and deodorization process. During this process, the air pump is activated, drawing outside air into the decolorizing and deodorizing barrel. The increased air pressure in the upper half of the barrel pushes the diesel fuel downwards, allowing it to quickly pass through the deodorizing, decolorizing, and stainless steel filter plates. This ensures that the diesel fuel is in full contact with the decolorizing and deodorizing layers, thereby improving the decolorization and deodorization effect.

[0019] 2. If repeated decolorization and deodorization are required, the second solenoid valve can be closed and the first solenoid valve opened. At the same time, the oil pump will start, and the oil pump will pump the diesel fuel at the bottom of the decolorization and deodorization tank back to the upper part of the decolorization and deodorization tank for secondary decolorization and deodorization. If secondary treatment is not required, the first solenoid valve can be closed and the second solenoid valve opened, and the oil pump can deliver the treated diesel fuel out of the decolorization and deodorization tank. During this process, some impurities remaining in the diesel fuel will be filtered out by the first filter cartridge. The plug can be unscrewed to clean the impurities filtered in the lower part of the decolorization and deodorization tank, thus facilitating the cleaning of the impurities filtered inside the decolorization and deodorization tank.

Detailed Implementation

[0027] This application embodiment provides a biodiesel pre-fraction decolorization and deodorization device, effectively solving the technical problem of the aforementioned decolorization and deodorization devices that rely on rotating deodorizers for deodorization. The distilled gas has difficulty fully contacting the deodorizer, hindering thorough decolorization and deodorization. In this device, diesel fuel enters the decolorization and deodorization tank and remains in the upper half. Then, under gravity, the diesel slowly seeps into the lower half of the tank. During this process, the decolorizing layer adsorbs pigments and other substances from the passing diesel fuel, and the deodorizing layer adsorbs odors. A stainless steel filter plate allows diesel fuel to pass through while preventing the decolorizing and deodorizing layers from falling to the bottom of the tank, thus completing the decolorization and deodorization process. During this process, an air pump is activated, drawing outside air into the decolorization and deodorization tank. The increased air pressure in the upper part pushes the diesel fuel downwards, allowing it to quickly pass through the deodorizing layer, decolorizing layer, and stainless steel filter plate. This ensures that the diesel fuel fully contacts the decolorizing and deodorizing layers, improving the decolorizing and deodorizing effect. If repeated decolorizing and deodorizing is required, the second solenoid valve can be closed and the first solenoid valve opened. Simultaneously, the oil pump starts, drawing the diesel fuel from the bottom of the decolorizing and deodorizing barrel back to the upper part for secondary decolorizing and deodorizing. If secondary treatment is not required, the first solenoid valve is closed and the second solenoid valve opened, allowing the oil pump to deliver the treated diesel fuel out of the decolorizing and deodorizing barrel. During this process, some impurities remaining in the diesel fuel will be filtered out by the first filter cartridge. The plug can be unscrewed to clean the impurities filtered in the lower part of the decolorizing and deodorizing barrel, facilitating the cleaning of impurities filtered inside the decolorizing and deodorizing barrel.

However, the distilled gas is difficult to fully contact the deodorizer, thus making it difficult to achieve sufficient decolorization and deodorization. The overall idea is as follows:

A sealing plug 17 is slidably installed in both the air inlet and the oil inlet. A spring 18 is installed below the sealing plug 17. The sealing plug 17 will block the air inlet and the oil inlet under the elastic force of the spring 18. A second filter cartridge 16 for filtering external impurities is installed in the oil inlet.

[0033] Base 1: Serves as the main frame of the entire equipment, providing installation and support for other components;

[0034] Decolorizing and deodorizing chamber 2: This is the main chamber for diesel decolorizing and deodorizing treatment;

[0035] Air pump 3: draws outside air into the decolorizing and deodorizing barrel 2, increases the air pressure in the upper part of the decolorizing and deodorizing barrel 2, and pushes diesel fuel through the decolorizing and deodorizing components quickly;

[0036] Air pipe 4: It serves to connect the decolorizing and deodorizing barrel 2 and the air pump 3;

[0037] Liquid guide tube 5: Used for transporting diesel fuel after decolorization and deodorization;

[0038] Oil pump 6: When secondary treatment or discharge of diesel is required, the diesel below the decolorization and deodorization tank 2 is pumped to the upper part of the decolorization and deodorization tank 2, or the decolorization and deodorization tank 2 is pulled out.

[0039] First solenoid valve 7: Opens the channel for diesel recirculation and secondary treatment;

[0040] Second solenoid valve 8: Opens the channel for the processed diesel output;

[0041] Stainless steel filter plate 9: Divides the decolorizing and deodorizing barrel 2 into upper and lower chambers, allowing diesel fuel to pass through while preventing the decolorizing layer 11 and deodorizing layer 12 from falling off;

[0050] Working principle:

[0051] The first step involves pouring the diesel fuel to be treated into the decolorizing and deodorizing tank 2 through the inlet. During this process, impurities in the diesel fuel will be filtered out by the second filter cartridge 16. After entering the decolorizing and deodorizing tank 2, the diesel fuel will remain in the upper half of the tank. Then, under the action of gravity, the diesel fuel will slowly seep into the lower half of the tank. During this process, the decolorizing layer 11 will adsorb pigments and other substances in the diesel fuel, and the deodorizing layer 12 will adsorb odors. The stainless steel filter plate 9 allows the diesel fuel to pass through while preventing the decolorizing layer 11 and the deodorizing layer 12 from falling to the bottom of the decolorizing and deodorizing tank 2, thus completing the decolorization and deodorization process. During this process, the air pump 3 is started, which will draw outside air into the decolorizing and deodorizing tank 2. The increased air pressure in the upper half of the tank will push the diesel fuel downward, allowing it to quickly pass through the deodorizing layer 12, the decolorizing layer 11, and the stainless steel filter plate 9.

[0052] The second step involves closing the second solenoid valve 8 and opening the first solenoid valve 7. Simultaneously, the oil pump 6 will start, pumping the diesel fuel from the bottom of the decolorizing and deodorizing tank 2 back to the upper part of the tank for secondary decolorizing and deodorizing. If secondary treatment is not required, close the first solenoid valve 7 and open the second solenoid valve 8. The oil pump 6 will then pump the treated diesel fuel out of the decolorizing and deodorizing tank 2. During this process, some impurities remaining in the diesel fuel will be filtered out by the first filter cartridge 14. Unscrew the plug 13 to clean the impurities filtered out in the lower part of the decolorizing and deodorizing tank 2.

[0053] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation.
