[0020] In response to the drawbacks of the prior art, the utility model provides a device for treating oil mist lubrication exhaust gas, which simultaneously transports the oil mist exhaust gas and cooling water to a condenser made using the Tesla valve principle for heat exchange, so that the oil mist exhaust gas is decelerated in the condenser and fully contacts and cools the fins of the condenser, so that the small oil droplets in the oil mist exhaust gas are cooled and then combined with water droplets and impurities in the air to condense into larger droplets and separate from the air. Finally, the cooled air is filtered through a filter to remove residual substances therein and obtain clean air.

[0021] See Figure 1 and Figure 2 The utility model mainly includes an air intake pipe 1, an upper shell 2, a condenser 3, a lower shell 4, an oil drain valve 5, an oil receiving box 6, a filter 7 and an exhaust pipe 8.

[0022] The condenser 3 mainly includes an outer shell 3-2, a vertical rectangular tube 3-3, fins 3-4 and a spoiler 3-5. A water inlet 3-1 is provided at the lower part of the right side wall of the outer shell 3-2, and a water outlet 3-6 is provided at the upper part of the left side wall. Multiple vertical rectangular tubes 3-3 are located inside the outer shell 3-2. The upper end of each vertical rectangular tube 3-3 is connected to an air inlet on the top plate of the outer shell 3-2, and the lower end is connected to an air outlet on the bottom plate of the outer shell 3-2. Multiple fins 3-4 arranged in a vertical direction are provided on the left and right walls of the vertical rectangular tube 3-3. One side of each fin 3-4 is fixedly connected to the inner wall of the vertical rectangular tube 3-3, and the other side is inclined upward. A spoiler 3-5 parallel to the fin 3-4 is provided between two adjacent fins 3-4 above and below. The front end and rear end of the spoiler 3-5 are respectively connected to the front side wall and rear side wall of the vertical rectangular tube 3-3. The inner holes of multiple vertical rectangular tubes 3-3 form the gas passages of condenser 3. The upper ends of the vertical rectangular tubes 3-3 serve as the gas passage entrances, and the lower ends as the gas passage exits. The space between the outer walls of the vertical rectangular tubes 3-3 and the inner wall of the outer shell 3-2 forms a cooling water passage. Each vertical rectangular tube 3-3, along with its internal fins 3-4 and spoilers 3-5, forms a Tesla valve. The fins 3-4 and spoilers 3-5 redirect the flow of gas, slowing the airflow and increasing the distance traveled by the oil mist, thereby increasing the contact area between the oil mist and the fins. When the oil mist passes through the Tesla valve from top to bottom, it encounters significant resistance, slowing it down. This allows for sufficient heat exchange between the oil mist and the cooling water outside the vertical rectangular tubes 3-3, ensuring a cooling effect for the oil mist.

[0023] The fins 3-4 are made of stainless steel sheets with a thickness of 0.5 mm and a width of 70 mm, and the spoilers 3-5 are made of stainless steel sheets with a thickness of 0.5 mm and a width of 35 mm.

[0024] The upper housing 2 is located above the condenser 3, with its bottom connected to the gas passage inlet of the condenser 3. The air inlet pipe 1 is mounted on the top of the upper housing 2. The lower housing 4 is located below the condenser 3, with its top connected to the gas passage outlet of the condenser 3. An oil drain valve 5 is mounted on the bottom of the lower housing 4, with an oil receiving box 6 positioned below the oil drain valve 5. One end of an exhaust pipe 8 passes through the lower housing 4, and the other end is located outside the lower housing 4. A filter 7 is mounted on the exhaust pipe 8.

[0025] Figure 1 In the embodiment, three condensers 3 are provided to improve the cooling effect of the oil mist exhaust gas.

[0026] The entire treatment device is a vertical structure. Cooling water enters the condenser 3's housing 3-2 through the water inlet 3-1, exchanges heat with the gas inside the vertical rectangular tube 3-3, and then flows out through the water outlet 3-6. Oil mist exhaust gas generated during mechanical operation enters the upper housing 2 through the air inlet pipe 1. It is decelerated and cooled within the three-layer condenser 3, causing the small oil droplets in the oil mist exhaust gas to combine with water droplets and impurities in the air, condensing into larger droplets (liquefied oil) and separating from the air. The condensed droplets collect at the bottom of the lower housing 4. The oil level is monitored by an oil gauge located at the bottom of the lower housing 4. When the level reaches a certain height, the oil drain valve 5 is opened to discharge the liquid oil into the oil collection box 6 for collection and regular cleaning. After the oil and gas are separated, the exhaust gas passing through the condenser is filtered by filter 7 before being discharged.

[0027] In specific implementation, the sizes of the upper shell 2 and the lower shell 4, as well as the number of layers of the condenser can be changed according to different oil mist pressures, and the cooling water can also be changed to cooling gas.

[0028] The utility model has the advantages of simple structure, convenient operation, and can effectively remove oil mist, reduce the impact of oil mist on the environment and human body, and save processing costs.
