[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 housing 1 and a bearing 6 and a rotating mechanism arranged therein. The two ends of the rotating mechanism are connected to the upper and lower parts of the housing 1 through the bearings 6. The housing 1 is also provided with an oil inlet B, an oil outlet C and a vacuum pump connection port A. An oil pipeline is also provided inside the rotating mechanism. 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 disc 2, an annular disc 3, a threaded clamp 4, a rotating shaft 5, and an adjusting ring 7. The rotating shaft 5 is externally sleeved with several rotating thrust discs 2, several annular discs 3, and the adjusting ring 7. The rotating thrust discs 2 and annular discs 3 are alternately stacked, with the adjusting ring 7 positioned at the top. Two threaded clamps 4 secure the rotating thrust discs 2, several annular discs 3, and the adjusting ring 7 together from top to bottom. The ends of the rotating shaft 5 are connected to the upper and lower parts of the housing 1 via bearings 6.

[0035] The rotating shaft 5 is hollow, with the lower portion of the cavity connected to the oil inlet B. The outer shell of the rotating shaft 5 is provided with several rotating shaft holes that communicate with the annular groove 22, allowing oil to flow from the oil inlet B through the rotating shaft holes into the annular groove 22. A stop is provided at the bottom of the rotating shaft 5, connected to the inner cavity of the housing via a bearing 6. The stop cooperates with an adjusting ring 7 to facilitate the clasp 4 to secure the rotating thrust plates 2 and the annular plates 3 together as a single unit from top to bottom.

[0036] The adjusting ring 7 is used to adjust the axial clearance to ensure that the rotating mechanism rotates flexibly; it prevents the clearance from being too small to prevent the rotating mechanism from getting stuck or rotating inflexibly.

[0037] The thrust plate 2 is a circular ring structure, comprising a body 21. The inner wall of the body 21 is provided with an annular groove 22. A number of nozzles 23 are evenly distributed on the outer surface of the body 21, connected to the annular groove 22 by an oil passage. A number of holes 24 are evenly distributed on the outer cylindrical surface of the body 21, with the outlet direction of the holes 24 parallel to the circumference. As the oil is ejected from the thrust plate 2, a reaction force is generated, pushing the thrust plate 2 in the opposite direction around the axis 5. Due to the connection and fixing effect of the screw clip 4, the annular plate 3 rotates synchronously with the thrust plate.

[0038] The annular disk 3 has a central opening for receiving the rotating shaft 5. The annular disk 3 is thin and features multiple concentric raised bands on its surface, extending from the inner ring to the outer ring. These raised bands create an oil film on the oil spilled onto the annular disk 3 due to the centrifugal force of the rotation. This film flows from the inner side of the annular disk to the outer side, becoming thinner after passing through the raised bands. The water in the oil vaporizes under vacuum, transforming into gaseous water, achieving oil-water separation.

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

[0040] The negative pressure value of the inner cavity of the housing 1 is ≤45kPa, 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 connect a vacuum pump to the vacuum pump connection port A on the upper portion of the housing 1 using a vacuum pump to form a vacuum environment in the housing 1 .

[0043] In the second step, the engine oil (temperature ≥80°C, pressure 1-2 bar) from the hydrogen fuel internal combustion engine is introduced through the oil inlet B at the bottom of the housing 1. After reaching the inner cavity of the rotating shaft 5, the oil enters the annular groove 22 of the rotating thrust disc 2 through the rotating shaft hole on the outer wall. It is then ejected from the nozzle 23 through the oil channel of the rotating thrust disc 2 and falls onto the annular disc 3. When the oil is ejected from the rotating thrust disc 2, it generates a reaction force, pushing 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 oil spilled on the annular disc 3 forms an oil film under the action of the centrifugal force of the rotation. The oil film flows from the inside of the annular disc to the outside, passing through multiple raised rings and becoming further thinner. The water in the oil begins to vaporize under vacuum conditions and becomes gaseous water, achieving oil-water separation. The gaseous water is extracted from the A interface on the top of the housing 1 by the vacuum pump.

[0044] In the third step, the dehydrated oil will gather 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 dehydrating 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 principles of the present invention should be included in the scope of protection of the present invention.
