DETAILED DESCRIPTION
[0018] In order to more clearly illustrate the technical scheme of the embodiments of the present application, the drawings needed in the embodiment description will be briefly introduced. Obviously, the drawings in the following description are some embodiments of the present application, and other drawings can also be obtained by those skilled in the art without creative labor.
[0019] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, therefore, the present application is not limited to the specific embodiments disclosed in the following description.
[0020] Embodiment 1, as Figs. 1-2As shown, an oil mist secondary separation oil product recovery device includes an oil tank 1, which serves as an oil product storage container, and the oil mist recovered oil product is also stored in the oil tank 1. A reasonably designed oil tank 1 can effectively maintain negative pressure and avoid oil mist backflow. The oil tank 1 is connected to an oil mist separator 3 through a separation pipeline 2. The oil mist separator 3 can separate the oil in the oil mist. By separating the oil from the gas, the efficient oil mist separation process can reduce environmental oil smoke pollution, while returning most of the oil to the oil tank 1, reducing resource waste.
[0021] The separation pipeline 2 connects the oil tank 1 and the oil mist separator 3 to transfer the oil mist. The oil mist separator 3 is connected to an oil smoke fan 7 through a connection pipeline 6. The oil smoke fan 7 provides the necessary airflow power to help the oil mist transport to a secondary separator 10, effectively promotes the further separation of the oil mist by increasing the airflow speed, and improves the recovery efficiency of the oil product.
[0022] The connection pipeline 6 connects the oil mist separator 3 and the oil smoke fan 7 to transfer the separated oil mist and gas. A reasonably designed connection pipeline 6 can reduce pressure loss and improve the efficiency of the overall airflow. The oil smoke fan 7 is connected to the secondary separator 10 through a smoke delivery pipeline 9. The secondary separator 10 performs secondary separation on the oil mist to capture finer oil, which can significantly improve the oil separation efficiency and further reduce emissions and oil waste. The smoke delivery pipeline 9 transports the oil mist to the secondary separator 10 for further separation processing. A good smoke delivery design can optimize the airflow path and improve the separation effect of the oil mist. The secondary separator 10 is provided with an oil return pipe 11 at one end of the bottom. The oil return pipe 11 leads the separated oil from the secondary separator 10 back to the oil tank 1, achieving effective recovery of the oil product and minimizing resource waste and environmental pollution.
[0023] The specific design of the above key components will be described below:
[0024] The oil mist separator 3 is provided with an exhaust pipeline 4 on one side, and the exhaust pipeline 4 is provided with an exhaust valve 5 at the end. The exhaust pipeline 4 adopts a pipeline with an appropriate diameter, and the material is selected from PVC or stainless steel which is resistant to oil and corrosion. The exhaust pipeline 4 is designed in an inclined shape to facilitate the smooth exhaust of oil smoke. The exhaust valve 5 is selected from an electric or pneumatic valve. The exhaust pipeline 4 can effectively guide the residual part of the oil mist after the oil mist separator 3 to the outside without accumulating oil smoke, reducing environmental pollution. The exhaust valve 5 can effectively control the amount of exhaust oil smoke when needed to ensure environmental protection and safety.
[0025] The oil fume fan 7 is connected with a motor 8. The oil fume fan 7 adopts a multi-wing centrifugal fan, and the selected motor 8 is a high-efficiency variable-frequency driving motor 8, which adopts an IP54 standard, and ensures stable operation in a harsh environment. The oil fume fan 7 can provide sufficient air flow power to send the oil mist into the secondary separator 10 for treatment, and ensure that the pressure change in the separator meets the design requirements. The motor 8 allows automatic adjustment of the fan speed according to the load, avoids energy waste, and prolongs the service life of the equipment.
[0026] The oil return pipe 11 is provided with an oil return valve 12 at the end. The oil return pipe 11 is designed as a pipe with a diameter of Φ25mm-Φ40mm, and is made of oil-resistant materials such as fluoroplastic or stainless steel to prevent oil leakage and corrosion. The oil return valve 12 can be a manually or electrically controlled valve, and the material should also be selected from oil-resistant and corrosion-resistant materials. The oil return valve 12 has high sealing requirements. The oil return pipe 11 is responsible for effectively returning the oil after secondary separation to the oil tank 1, reducing resource waste. The oil return valve 12 plays a sealing role in the oil recovery process, avoiding oil leakage during the return process.
[0027] The smoke conveying pipe 9 is inserted into the oil mist separator 3, and the smoke collecting cone 13 is arranged at the top end of the smoke conveying pipe 9. The smoke collecting cone 13 is a hollow cone, and the bottom diameter of the smoke collecting cone 13 is greater than the diameter of the smoke conveying pipe 9. The smoke conveying pipe 9 is inserted from the bottom of the oil mist separator 3 to the secondary separator 10, and has sufficient air flow load. The smoke collecting cone 13 is designed as a hollow cone, which is convenient for the concentration of oil mist. The design of the smoke conveying pipe 9 can effectively transport the oil mist to the secondary separator 10, reducing the residence time of the oil mist in the pipe. The smoke collecting cone 13 can guide the oil mist to the center during the air flow process, and the oil mist adheres to the inner wall of the smoke collecting cone 13 and slides down along the inner wall of the smoke collecting cone 13 under the action of gravity to fall into the secondary separator 10 to collect the oil.
