Description

Technical Field

[0001] This utility model relates to a stripping deodorization device for recycled lubricating oil base oil. Background Technology

[0002] In the production process of recycled lubricating oil base oil, stripping deodorization is required. Oil and water vapor are separately introduced into a stripping deodorization unit, where the water vapor comes into contact with the oil and carries away odorous substances. However, existing stripping deodorization units do not allow sufficient contact between the water vapor and the oil, which affects the effectiveness and quality of the stripping deodorization process. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a stripping deodorization device for regenerated lubricating oil base oil, comprising: a vertically positioned cylindrical main body; an inlet pipe (sealed and welded to the top wall of the main body) penetrating the top wall of the main body and coaxial with the main body; a vertically positioned cylindrical distributor head fixed at the bottom end of the inlet pipe; multiple horizontally positioned spray pipes (the distributor head has a delivery channel connecting the inlet pipe to each spray pipe) fixed to the side circumferential wall of the distributor head; a vertically positioned rotating shaft penetrating the bottom wall of the main body and rotatably connected to the distributor head, extending to the top of the main body and coaxial with the main body; and multiple disc-shaped partition plates fixed on the rotating shaft and vertically evenly distributed (the partition plates are connected to the rotating shaft). The shaft is coaxial, with a packing layer on each partition plate (the uppermost packing layer is located below the bearing and each nozzle), a motor at the bottom of the rotating shaft, an air inlet pipe and a liquid outlet pipe connected to the bottom of the main cylinder (both the air inlet pipe and the liquid outlet pipe are located below the bottommost partition plate), and an exhaust pipe connected to the top of the main cylinder (the air inlet pipe is located above the topmost partition plate). Each partition plate is provided with a fan-shaped mesh area, and the fan-shaped mesh area is evenly distributed with vertical through holes (the outer diameter of the packing in the packing layer is larger than the diameter of the vertical through holes), and the fan-shaped mesh areas of two vertically adjacent partition plates are staggered (that is, the fan-shaped mesh area of ​​the upper partition plate is completely staggered from the fan-shaped mesh area of ​​the lower partition plate).

[0004] Preferably, it also includes: a support foot located at the bottom of the main cylinder.

[0005] Preferably, the support leg is fixedly connected to the motor via a connecting frame.

[0006] Preferably, the plurality of nozzles are evenly distributed circumferentially along the side wall of the dispensing head.

[0007] Preferably, it also includes: a plurality of nozzles disposed on the bottom wall of the nozzle and evenly distributed along the length of the nozzle.

[0008] Preferably, the rotating shaft is rotatably connected to the dispensing head via a bearing (the outer ring of the bearing is fixedly connected to the bottom end of the dispensing head, and the inner ring of the bearing is fixedly connected to the top end of the rotating shaft).

[0009] Preferably, it also includes a rotary seal that seals the gap between the rotating shaft and the bottom wall of the main cylinder.

[0010] Preferably, it also includes: a cleaning port located on the side wall of the main cylinder and corresponding to the packing layer (the cleaning port is closed by an openable sealing cap).

[0011] Preferably, the central angle of the fan-shaped mesh area is 90 to 120 degrees.

[0012] Preferably, the filler in the filler layer is a ceramic filler.

[0013] The advantages and beneficial effects of this utility model are as follows: It provides a stripping deodorization device for regenerated lubricating oil base oil, which can increase the contact time between water vapor and oil, making the contact between water vapor and oil more sufficient, thereby improving the effect and quality of oil stripping deodorization.

[0014] During the upward movement of water vapor and the downward movement of oil, the motor drives the rotating shaft to rotate, which in turn drives the partition plates and the packing layers on each partition plate to rotate. The fan-shaped mesh areas of two vertically adjacent partition plates are staggered (i.e., the fan-shaped mesh areas of the upper partition plate and the lower partition plate are completely staggered). This increases the contact time between water vapor and oil, making the contact between water vapor and oil more sufficient, thereby improving the effect and quality of oil stripping deodorization.

[0017] The specific technical solution of this utility model is as follows: like Figure 1 and Figure 2As shown, this utility model provides a stripping deodorization device for regenerated lubricating oil base oil, comprising: a vertically placed cylindrical main body 1; an inlet pipe 21 penetrating the top wall of the main body 1 and coaxial with the main body 1 (the inlet pipe 21 is sealed and welded to the top wall of the main body 1); a vertically placed cylindrical distributor head 22 fixed at the bottom end of the inlet pipe 21; and multiple horizontally placed spray pipes 23 fixed to the side circumferential wall of the distributor head 22 and evenly distributed along the side circumferential wall of the distributor head 22 (the distributor head 22 is provided with a liquid delivery channel that connects the inlet pipe 21 to each spray pipe 23 respectively); and a spray pipe 23 located at the bottom of the spray pipe 23. Multiple nozzles 24 evenly distributed along the length of the nozzle 23; a vertically oriented rotating shaft 31 that penetrates the bottom wall of the main cylinder 1, extends to the top of the main cylinder 1, and is coaxial with the main cylinder 1; a flat bearing 32 that rotatably connects the bottom end of the distributor head 22 to the top end of the rotating shaft 31 (the outer ring of the bearing 32 is fixed to the bottom end of the distributor head 22, and the inner ring of the bearing 32 is fixed to the top end of the rotating shaft 31); a rotary seal 33 that seals the gap between the rotating shaft 31 and the bottom wall of the main cylinder 1; and multiple disc-shaped partition plates 4 fixed on the rotating shaft 31 and vertically evenly distributed (the partition plates 4 are coaxial with the rotating shaft 31). The packing layer 5 is located on each partition plate 4 (the uppermost packing layer 5 is located below the bearing 32 and each nozzle 24), the motor 34 is located at the bottom of the rotating shaft 31, the support foot 11 is located at the bottom of the main cylinder 1, the connecting frame 12 that fixes the motor 34 to the support foot 11, the air inlet pipe 6 and the liquid outlet pipe 7 are externally connected to the bottom of the main cylinder 1 (both the air inlet pipe 6 and the liquid outlet pipe 7 are located below the lowermost partition plate 4), the exhaust pipe 8 is externally connected to the top of the main cylinder 1 (the air inlet pipe 6 is located above the uppermost partition plate 4), and the packing layer 5 is located on the side wall of the main cylinder 1. The corresponding cleaning port 9 (the cleaning port 9 is closed by an openable sealing cap); each partition plate 4 is provided with a fan-shaped mesh area 41, and the fan-shaped mesh area 41 is evenly distributed with vertical through holes 42 (the outer diameter of the filler in the filler layer 5 is larger than the diameter of the vertical through holes 42), and the fan-shaped mesh areas 41 of two vertically adjacent partition plates 4 are staggered (that is, the fan-shaped mesh area 41 of the upper partition plate 4 and the fan-shaped mesh area 41 of the lower partition plate 4 are completely staggered); the central angle of the fan-shaped mesh area 41 is 90 to 120 degrees; the filler in the filler layer 5 is ceramic filler.

[0018] The working principle of the stripping deodorization device for regenerated lubricating oil base oil of this utility model includes: Water vapor is input through the air inlet pipe 6, and the water vapor input through the air inlet pipe 6 passes from bottom to top through the vertical through holes 42 of the fan-shaped mesh area 41 of each partition plate 4 and each packing layer 5; The oil to be stripped and deodorized is input through the inlet pipe 21, and the oil input through the inlet pipe 21 is diverted by the distributor head 22 to multiple nozzles 23, and then sprayed out by the nozzles 24 on each nozzle 23; the oil sprayed out by the nozzles 24 passes from top to bottom through the vertical through holes 42 of each packing layer 5 and the fan-shaped mesh area 41 of each partition plate 4. During the upward movement of water vapor and the downward movement of oil, the water vapor comes into contact with the oil in each packing layer 5, and carries away the odorous substances in the oil through the water vapor; finally, the water vapor carrying the odorous substances is discharged through the exhaust pipe 8, and the oil whose odorous substances have been carried away by the water vapor is discharged through the drain pipe 7. Furthermore, during the upward movement of water vapor and the downward movement of oil, the motor 34 drives the rotating shaft 31 to rotate, which in turn drives each partition plate 4 and the packing layer 5 on each partition plate 4 to rotate. The fan-shaped mesh areas 41 of two vertically adjacent partition plates 4 are staggered (i.e., the fan-shaped mesh areas 41 of the upper partition plate 4 and the fan-shaped mesh areas 41 of the lower partition plate 4 are completely staggered). This increases the contact time between water vapor and oil, making the contact between water vapor and oil more sufficient, thereby improving the effect and quality of oil stripping deodorization. In addition, after the packing layer 5 has been used for a certain period of time, new packing can be replaced through the cleaning port 9.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
