Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil-water separator technology, specifically to an oil-water separator with an inclined plate structure. Background Technology
[0002] Inertial separators are widely used in compressed gas equipment. Their structure typically consists of components such as an inlet pipe, a separation chamber, an outlet pipe, baffles, and guide plates. The inlet pipe introduces the oil-water mixture into the separator; the separation chamber is the main working area, with a large internal space to provide a space for oil-water separation; the outlet pipe discharges the separated oil and water respectively; circular baffles and guide plates are installed inside the separation chamber to change the flow direction and velocity of the fluid.
[0003] The working principle of an inertial separator is that when an oil-water mixture enters the separation chamber from the inlet pipe at a certain velocity, it encounters obstacles such as guide plates and baffles, causing changes in the flow direction and velocity of the fluid. Due to the different densities of oil and water, and relying on the different inertial characteristics of oil and water, the separator utilizes its structural features to separate the denser oil and water, which are then discharged through the drain port.
[0004] Currently available baffles and deflectors have structural defects. During rapid gas reversals, water, with its higher density and inertia, is more likely to maintain its original flow direction and be discharged quickly from the bottom drain. However, oil, with its lower density and inertia, is more likely to change direction with the fluid flow and, due to buoyancy, floats with the gas flow and is discharged through the outlet. This carries some oil and water out of the separator, causing downstream gas contamination and excessively high oil-water content, resulting in low cleanliness of the final gas and severely impacting downstream equipment operation. Furthermore, the impact of gas flow velocity and the corrosive effect of the oil-water mixture can easily cause welded baffles and circular deflectors to break at welded joints, affecting separator operation and the normal operation of the entire system.
[0005] Therefore, there is an urgent need for an oil-water separator with an inclined blade structure to address the technical problems described above. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide an oil-water separator with a slanted blade structure.
[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is an oil-water separator with an inclined plate structure, comprising:
[0008] The system comprises a steel main body shell, inclined blade guide vanes, circular baffles, and conical baffles. The top of the steel main body shell is equipped with an air guide pipe. The steel main body shell also has an exhaust port communicating with the air guide pipe and an air inlet communicating with its interior. The inclined blade guide vanes have mounting holes in their middle, allowing them to be installed at the lower end of the air guide pipe. The outer wall of the inclined blade guide vanes is tightly fitted to the inner wall of the steel main body shell. Multiple inclined guide grooves are evenly distributed on the outer periphery of the inclined blade guide vanes. A drain port is located at the bottom of the steel main body shell. Multiple fixing rods are evenly distributed at the lower ends of both the circular and conical baffles. The conical baffle is located at the bottom of the steel main body shell and connected to the bottom of the steel main body shell via the fixing rods. The circular baffle is located inside the steel main body shell and above the conical baffle, connected to the top of the conical baffle via the fixing rods.
[0009] Both the circular baffle and the conical baffle are uniformly provided with multiple O-shaped air holes that penetrate the circular baffle and the conical baffle.
[0010] As an improvement, the fixing rod is welded to the steel main body shell, the circular baffle, and the conical baffle, respectively.
[0011] As an improvement, both the inclined blade guide vanes and the circular baffles are made of stainless steel.
[0012] The advantages of this utility model compared with the prior art are as follows:
[0013] Multiple inclined guide grooves are evenly arranged on the outer circumference of the inclined blade-type flow guide plate, thereby changing the normal flow direction and velocity of the gas. Through the principle of inertia and gravity, water and oil with higher density flow along the circumferential wall to the bottom in the direction of airflow, thus separating water and oil of different densities in the gas. At the same time, the circular baffle plate and conical baffle plate with O-shaped air holes prevent oil and water with lower density from floating, thereby reducing the discharge of oil-water mixture. It effectively solves the problem of oil-water and gas separation efficiency in compressed gas equipment, purifies the compressed gas with excessive oil and water content, achieves the purpose of purification in the middle stage of compressed gas, and further benefits the purification of gas cleanliness in downstream filtration equipment.

[0023] The system comprises a steel main body shell 1, inclined blade guide vanes 2, circular baffles 3, and conical baffles 12. An air guide pipe 4 is located at the top inside the steel main body shell 1. An exhaust port 5 communicating with the air guide pipe 4 is located on the steel main body shell 1.

The outer wall of the inclined blade guide vane 2 is tightly fitted to the inner wall of the steel main body shell 1. The inclined guide vane 2 has a plurality of inclined guide grooves 8 evenly arranged on its outer periphery. The bottom of the steel main body shell 1 is provided with a drain port 9.

[0028] In specific implementation, this utility model
[0029] The oil-water mixture is introduced into the steel outer shell 1 through the air inlet 6. Multiple inclined guide grooves 8 are evenly distributed on the outer circumference of the inclined guide vanes 2, altering the normal flow direction and velocity of the gas. Through inertia and gravity, the denser water and oil flow downwards along the guide grooves 8 on the circumferential wall of the inclined guide vanes 2, and then flow towards the bottom along the inner circumferential wall of the steel outer shell 1. This separates the water and oil of different densities from the gas. Simultaneously, the circular baffles 3 and conical baffles 12 with O-shaped air holes 11 prevent the less dense oil and water from floating, thus reducing the discharge of the oil-water mixture. This effectively solves the problem of high oil-water content in compressed gas equipment, achieving the purpose of mid-stage purification of compressed gas and further improving the gas cleanliness of downstream filtration equipment. End-of-line testing shows that the oil content is ≤10mg / Nm³. 3 Dew point (-60℃~-78℃).
