Description

Technical Field

[0001] The utility model relates to the technical field of high-power engine ventilation pipeline systems, in particular to an oil-gas separation device for a ventilation pipeline. Background Art

[0002] High-power engines are now widely used in transportation, energy conversion, and manufacturing. Certain components of these engines, such as the crankcase, require independent ventilation systems to ensure internal pressure release. Because ventilation systems utilize pipes, these pipes are often bent to accommodate site layouts. In addition to the primary high-pressure gas, these pipes often contain evaporated oil and water vapor. Consequently, during engine operation, these vapors condense on the pipe walls. Over time, these vapors accumulate in the pipes, compromising the overall air permeability. To address this issue, we propose a ventilation pipe oil-gas separation device. Utility Model Content

[0003] The utility model provides an oil-gas separation device for a ventilating pipeline, which solves the problems raised by the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a breathable pipeline oil and gas separation device, including a condensation tube body, the bottom end of the condensation tube body is fixedly connected to a connecting pipe, and mounting flanges that can be connected to the breathable pipeline are respectively installed at the bottom end of the connecting pipe and the top of the condensation tube body. The mounting flange is cone-shaped, and the top of the connecting pipe extends into the interior of the condensation tube body. A concentrated tank for storing oil and water is formed between the bottom of the condensation tube body and the top of the connecting pipe, and a discharge pipe connected to the outside world is fixedly installed at the bottom of the concentrated tank.

[0005] Optionally, one end of the connecting tube extending into the interior of the condensation tube body is fixedly connected to a centralized guide seat, and the bottom of the centralized guide seat is inclined upward from the outside to the inside.

[0006] Optionally, a guide pipe is fixedly connected to the middle of the top of the centralized guide seat. The guide pipe is conical and spiral, and gradually extends downward from the inside to the outside, with one end of the guide pipe at the bottom, and a through hole is opened on the guide pipe.

[0007] Optionally, the bottom of the concentrating tank is in the shape of an annular arc, and the connection end between the discharge pipe and the concentrating tank is located at the lowest point of the arc of the concentrating tank.

[0008] Optionally, a condensation plate is fixedly connected to the inner wall of the condensation tube body, and the condensation plate is arc-shaped and concave upward.

[0009] Optionally, vertical vent holes are formed through the condensation plate, and the condensation plate is located directly above the guide tube.

[0010] The utility model has the following beneficial effects:

[0011] 1. The oil-gas separation device for the breathable pipeline has a tapered diameter-changing design of the condensation tube body. When the oil and gas pass through the device, the gas flow direction will be changed, so that part of the oil and water in the gas will condense on the inner wall of the tapered condensation tube body and gather at the bottom of the concentration tank. The collected oil and water will be discharged through the discharge pipe at the bottom, preventing the oil and water from condensing and gathering in the pipeline, thereby ensuring the air permeability of the entire pipeline.

[0012] 2. The oil-gas separation device of the breathable pipeline guides the oil, water and gas to the inner wall of the condensation tube body through the diversion of the guide tube, thereby preventing the oil, water and gas from directly passing through the condensation tube body, and then allowing the oil, water and gas to more fully contact the inner wall of the condensation tube body, thereby making the oil, water and gas condense more fully, thereby achieving a better oil and water discharge effect.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Due to the tapered diameter change design of the condensation tube body 2, the oil and gas will change the gas flow direction when passing through the device, so that part of the oil and water in the gas condenses on the inner wall of the tapered condensation tube body 2 and gathers at the bottom of the focusing tank 7, and the top end of the connecting pipe 4 extends into the interior of the condensation tube body 2, and a focusing tank 7 for storing oil and water is formed between the bottom of the condensation tube body 2 and the top of the connecting pipe 4, and a discharge pipe 3 connected to the outside world is fixedly installed at the bottom of the focusing tank 7, and the oil and water in the focusing tank 7 can be discharged through the discharge pipe 3.

The guide pipe 8 is conical and spiral, and the guide pipe 8 gradually extends downward from the inside to the outside. Under the guiding action of the centralized guide seat 6, the oil, water and gas can flow to the inner wall of the condensation tube body 2, and under the structural action of the centralized guide seat 6, the oil and water condensed in the centralized guide seat 6 can flow into the centralized tank 7, and one end of the guide pipe 8 is at the bottom. At the same time, a through hole is opened on the guide pipe 8, which enables the guide pipe 8 to be ventilated smoothly, avoiding blockage caused by excessive condensation of oil and water in the guide pipe 8.
