Description

Technical Field

[0001] This utility model relates to the field of engine technology, and more specifically, it relates to an integrated anti-condensate backflow oil-gas separation device. Background Technology

[0002] The oil-gas separator is a major component of the crankcase ventilation system. Its main function is to efficiently separate the engine oil in the crankcase blow-by gas, thereby preventing excessive oil evaporation, reducing the temperature inside the crankcase, and protecting the engine for normal operation.

[0003] For marine engines, the vent pipe of the open-circuit breather must be led outside the hull. Water vapor can escape from the crankcase vent pipe, especially in LNG or methanol / ethanol fuel engines where the water vapor concentration is higher. When the air humidity is high and the engine room temperature is low, the water vapor in the vent pipe can easily liquefy and flow into the engine. Figure 1 As shown, water vapor in the vent pipe 2 easily liquefies into water and flows into the oil-gas separator 1. Then, it flows into the engine through the oil return port of the oil-gas separator 1, causing the engine lubricating oil to emulsify, affecting the lubrication performance, damaging the engine, and significantly shortening the engine's service life. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the above-mentioned shortcomings of the prior art by providing an integrated anti-condensate backflow oil-gas separator, which prevents condensate in the vent pipe from flowing into the engine through the oil-gas separator, thereby effectively extending the service life of the engine.

[0005] The technical solution of this utility model is as follows: an integrated anti-condensate backflow oil-gas separation device includes an oil-gas separator, a vent pipe connected to the vent of the oil-gas separator, and a water storage pipe. The water storage pipe is installed at the bottom of the vent pipe, and the water storage pipe is perpendicular to and connected to the vent pipe. A drain pipe is provided at the bottom of the water storage pipe and is connected to it. A discharge valve is provided on the drain pipe. A detection pipe is provided on the water storage pipe, and a liquid level sensor is provided inside the detection pipe. The liquid level sensor is electrically connected to an alarm.

[0006] As a further improvement, the end of the detection tube away from the water storage pipe is arranged at an angle upward, and the angle α formed by the detection tube and the water storage pipe is an acute angle.

[0007] Furthermore, the outer wall surface of the oil-gas separator is in contact with the outer wall surface of the water storage pipe.

[0008] Furthermore, the outer wall surface of the drain pipe is provided with serrated protrusions.

[0009] Furthermore, both ends of the water storage pipe are provided with support frames. Each support frame includes a support rod and two connecting rods. The two ends of the support rod are respectively connected to one end of the two connecting rods. The support rod is provided with a mounting seat, and the mounting seat is provided with an arc-shaped groove that conforms to the circumferential surface of the vent pipe.

[0010] Furthermore, a rubber pad is provided at the bottom of the arc-shaped groove.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0021] See Figure 1-5An integrated anti-condensate backflow oil-gas separator includes an oil-gas separator 1, a vent pipe 2 connected to the outlet of the oil-gas separator 1, and a water storage pipe 3. The water storage pipe 3 is installed at the bottom of the vent pipe 2, and is perpendicular to and connected to the vent pipe 2. A drain pipe 6 is provided at the bottom of the water storage pipe 3, and a discharge valve 7 is provided on the drain pipe 6. A detection pipe 4 is provided on the water storage pipe 3, and a liquid level sensor 5 is provided inside the detection pipe 4. The liquid level sensor 5 is electrically connected to an alarm 14. Condensate in the vent pipe 2 flows along its inner surface... The water flows into the water storage pipe 3. When the water level in the water storage pipe 3 rises to the connection between the water storage pipe 3 and the detection pipe 4, the condensate flows into the detection pipe 4. When the water level rises to the level sensor, the level sensor is energized and outputs a signal, the alarm sounds, and then the drain valve 7 is opened to discharge the condensate in the water storage pipe 3. By setting a water storage pipe before the oil-gas separator 1, the condensate in the vent pipe 2 flows into the water storage pipe, thereby preventing the condensate in the vent pipe from flowing into the engine through the oil-gas separator, effectively extending the engine's service life.

[0022] In this embodiment, the end of the detection tube 4 away from the water storage pipe 3 is arranged at an angle upward, and the angle α formed by the detection tube 4 and the water storage pipe 3 is an acute angle. The height of the liquid level sensor is lower than the height of the connection between the water storage pipe 3 and the vent pipe 2. When the drain valve 7 is opened to drain the condensate in the water storage pipe 3, it is convenient for the condensate in the detection tube 4 to flow out, and it is avoided that condensate is discharged from the detection tube 4 during the discharge, which would cause the liquid level sensor 5 to detect inaccurately.

[0023] In this embodiment, the outer wall of the oil-gas separator 1 is in contact with the outer wall of the water storage pipe 3, shortening the distance between the connection between the vent pipe 2 and the oil-gas separator 1 and the connection between the vent pipe 2 and the water storage pipe 3, thereby reducing the condensate precipitated in the vent pipe 2 between the oil-gas separator 1 and the water storage pipe 3; at the same time, it is convenient to connect the water storage pipe 3 and the oil-gas separator 1 together, improving the firmness of the water storage pipe 3.

[0024] In this embodiment, the outer wall of the drain pipe 6 is provided with serrated protrusions 9. When draining, a plastic hose can be inserted into the drain pipe 6 to guide the condensate in the water storage pipe 3 to other locations. The protrusions 9 on the outer wall of the drain pipe 6 can form a seal with the plastic hose to prevent leakage and avoid other malfunctions.

[0025] In this embodiment, support frames 10 are provided at both ends of the water storage pipe 3. Each support frame 10 includes a support rod 101 and two connecting rods 102. The two ends of the support rod 101 are respectively connected to one end of the two connecting rods 102. A mounting seat 11 is provided on the support rod 101. The mounting seat 11 is provided with an arc-shaped groove 12 that is adapted to the circumferential surface of the vent pipe 2. Two support frames 10 are installed on the vent pipe 2. The two support frames 10 are located on both sides of the connection between the vent pipe 2 and the water storage pipe 3, respectively, to stabilize the vent pipe 2. The mounting seat 11 on the support rod 101 increases the contact area between the lower part of the vent pipe 2 and the support rod 101, thereby improving the stability of the vent pipe 2.

[0026] In this embodiment, a rubber pad 13 is provided at the bottom of the arc groove 12. The support frame 10 is usually connected to the deck. The lower part of the vent pipe 2 is installed on the rubber pad 13, which can prevent the vibration of the deck from being transmitted to the vent pipe 2 and affecting the vent pipe 2, and prevent long-term vibration from reducing the sealing between the vent pipe 2 and other connected components, resulting in leakage.

[0027] 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 modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
