Description

Technical Field

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

[0002] An important process in oil refining is deacidification. Currently, there are two methods for deacidification: alkali refining and physical refining. Since the alkali refining method has a low oil yield and produces too much wastewater and waste residue, the physical refining method is widely adopted by the industry. The physical refining method is based on the principle that the boiling point of fatty acids in oil is lower than that of oil. The oil is heated and steam distilled to remove the fatty acids while the oil is retained. However, for crude oil with an acid value (AV>6), it is difficult to make the finished oil meet the international first-class oil standard without alkali refining.

[0003] The prior art, which can be referenced in the Chinese authorized utility model patent publication number CN211734298U, specifically relates to a deacidification and deodorization device for oil refining, comprising a deacidification chamber, an oil inlet pipe fixedly mounted on one side of the chamber, a first packing material fixedly mounted on the upper side of the chamber, a second packing material fixedly mounted on the bottom of the first packing material, a vacuum pump fixedly connected above the chamber, a deodorization tank fixedly connected to the bottom of the chamber, and a first oil guide plate fixedly mounted inside the tank. This deacidification and deodorization device for oil refining can channel oil into a film for contact with hot steam.

[0004] In actual use, although the above-mentioned prior art uses the grooves on the upper parts of the oil guide plates 1 and 2 to guide the grease into a film, the grease is still relatively concentrated after the guidance, the thickness of the formed film is relatively high, and the contact effect with the hot steam is not very good. Therefore, the deodorization efficiency is slow and the effect is not ideal. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes a deacidification and deodorization device for oil refining, which is used to solve the problems in the above-mentioned prior art that the film formed is thick and the contact effect with hot steam is not very good, resulting in slow deodorization efficiency and unsatisfactory effect.

[0006] To achieve the above-mentioned purpose, the utility model provides a deacidification and deodorization device for oil refining, comprising: a deodorizing tank, the bottom of which is connected to and provided with a discharge pipe; an input unit connected to the interior of the deodorizing tank, arranged at the top of the deodorizing tank, and used to transport oil into the deodorizing tank; a collecting hopper arranged at the top of the deodorizing tank, the bottom of the collecting hopper being tubular; a diverter cylinder rotatably mounted on the bottom of the collecting hopper, the diverter cylinder being connected to the collecting hopper; a plurality of third diverter tubes circumferentially arranged on the diverter cylinder, and the third diverter tubes being connected to the diverter cylinder; a steam input unit connected to the deodorizing tank, and used to input hot steam into the deodorizing tank; wherein the bottom of each of the third diverter tubes is connected to and provided with a plurality of second nozzles.

[0008] Furthermore, a plurality of gear teeth are provided on the top of the diverter cylinder, and the plurality of gear teeth are distributed circumferentially around the gear teeth. One end of the rotating shaft is connected to a gear, and the rotating shaft is engaged with the diverter cylinder through the gear and the gear teeth.

[0009] Furthermore, a linkage shaft is fixedly installed at the bottom of the diverter cylinder, a connecting block is fixedly installed at the bottom of the linkage shaft, a plurality of fan blades are provided on the outer wall of the connecting block, wherein the top of the fan blades is provided with an inclined surface, and the upper part of the connecting block is conical.

[0010] Furthermore, the steam input unit includes a steam heating tank fixed on the outer wall of the deodorizing tank, a diverter ring sleeved on the deodorizing tank, and a steam delivery pipe connecting the steam heating tank and the diverter ring, wherein the interior of the diverter ring is hollow, and a plurality of first nozzles are arranged inside the diverter ring, and one end of the first nozzle extends into the interior of the deodorizing tank.
