[0031] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0032] A hydrogen fuel internal combustion engine oil dehydration device, such as Figures 1 to 7As shown, it includes a shell 1 and a bearing 6 and a rotating mechanism arranged inside it. The two ends of the rotating mechanism are connected to the upper and lower parts of the shell 1 through the bearings 6; the shell 1 is also provided with an oil inlet B, an oil outlet C and a vacuum pump connection port A, and the rotating mechanism is also provided with an oil pipeline. The rotating mechanism is driven to rotate by the reaction force generated when the engine oil is sprayed out, and oil-water separation is achieved at the same time.

[0033] Preferably, the oil inlet B is located at the lower part of the housing 1, and the vacuum pump connection port A is located above the housing 1, so as to facilitate the vacuum pump to draw air.

[0034] The rotating mechanism includes a rotating thrust disk 2, an annular disk 3, a thread clamp 4, a rotating shaft 5 and an adjusting ring 7. The rotating shaft 5 is externally sleeved with a plurality of rotating thrust disks 2, a plurality of annular disks 3 and an adjusting ring 7, and the rotating thrust disks 2 and annular disks 3 are alternately stacked, and the adjusting ring 7 is located at the top. Two thread clamps 4 fix the plurality of rotating thrust disks 2, a plurality of annular disks 3 and the adjusting ring 7 from top to bottom as a whole. The two ends of the rotating shaft 5 are connected to the upper and lower parts of the housing 1 through bearings 6.

[0035] The rotating shaft 5 is a cavity structure, the bottom of the cavity is connected to the oil inlet B, and the outer shell of the rotating shaft 5 is provided with a plurality of rotating shaft holes connected to the annular groove 22, so that the oil can flow from the oil inlet B into the annular groove 22 through the rotating shaft holes. A baffle is provided at the bottom of the rotating shaft 5, and the bottom of the baffle is connected to the inner cavity of the housing through a bearing 6. The baffle cooperates with the adjusting ring 7 to facilitate the screw clamp 4 to fix the plurality of rotating thrust plates 2 and the plurality of annular plates 3 from top to bottom as a whole.

[0036] The adjusting ring 7 is used to adjust the axial clearance to ensure the flexible rotation of the rotating mechanism and to prevent the clearance from being too small to prevent the rotating mechanism from getting stuck or being inflexible.

[0037] The rotating thrust plate 2 is a circular ring structure, including a body 21, the inner wall of the body 21 is provided with an annular groove 22, and a plurality of nozzles 23 are evenly arranged on the outer surface of the body 21, and the nozzles 23 are connected to the annular groove 22 through an oil channel. A plurality of holes 24 are evenly distributed on the outer cylindrical surface of the body 21, and the outlet direction of the holes 24 is parallel to the tangent direction of the circumference. When the engine oil is sprayed out of the rotating thrust plate 2, a reaction force is generated, which pushes the rotating thrust plate 2 to rotate in the opposite direction around the rotating shaft 5; due to the connection and fixing effect of the screw card 4, the annular plate 3 rotates synchronously with the rotating thrust plate.

[0038] The annular disk 3 has a hole in the middle, which is used to sleeve the rotating shaft 5. The annular disk 3 is in the shape of a thin plate, and has multiple concentric ring belts on the surface from the inner ring to the outer ring. The concentric ring belts are convex structures. The concentric ring belts make the oil spilled on the annular disk 3 form an oil film under the action of the rotating centrifugal force. The oil film flows from the inside of the annular disk to the outside, and becomes thinner after passing through multiple convex ring belts. The water in the oil begins to vaporize into gaseous water under vacuum conditions, realizing oil-water separation.

[0039] The temperature of the oil entering the device is ≥80°C and the pressure is 1 bar to 2 bar; this temperature and pressure value is what the oil of a hydrogen fuel internal combustion engine can normally reach.

[0040] The negative pressure value of the inner cavity of the housing 1 is ≤45 kPa, and this requirement is related to the oil temperature.

[0041] The working principle of a hydrogen fuel internal combustion engine oil dehydration device is:

[0042] During operation, the first step is to use a vacuum pump or the like to connect the vacuum pump connection port A on the upper portion of the housing 1 to form a vacuum environment in the housing 1 .

[0043] In the second step, the engine oil (temperature ≥80°C, pressure 1bar~2bar) of the hydrogen fuel internal combustion engine is fed into the oil inlet B at the bottom of the housing 1. After the engine oil reaches the inner cavity of the rotating shaft 5, it enters the annular groove 22 of the rotating thrust disc 2 through the rotating shaft hole on the outer wall, and then sprays out from the nozzle 23 through the oil channel of the rotating thrust disc 2 and falls on the annular disc 3. When the engine oil sprays out of the rotating thrust disc 2, a reaction force is generated, which pushes the rotating thrust disc 2 to rotate in the opposite direction around the rotating shaft 5; due to the connection and fixing effect of the wire clip 4, the annular disc 3 rotates synchronously with the rotating thrust disc 2. The engine oil spilled on the annular disc 3 forms an oil film under the action of the rotating centrifugal force. The oil film flows from the inside of the annular disc to the outside, and needs to pass through multiple raised ring belts to become further thinner. The water in the engine oil begins to vaporize into gaseous water under vacuum conditions, realizing oil-water separation. The gaseous water is pumped away from the A interface on the upper part of the housing 1 by the vacuum pump.

[0044] In the third step, the dehydrated oil will be collected at the lower part of the housing 1 and return to the internal combustion engine through the oil outlet C.

[0045] The hydrogen fuel internal combustion engine oil dehydration device is also suitable for the dehydration of oil in equipment such as diesel engines, gasoline engines, gas engines and compressors.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
