Abstract
Description
Technical Field
[0001] The utility model relates to the field of oil-gas separation equipment, in particular to an oil-gas separator. Background Art
[0002] Compared with dry chillers, flooded chillers have greatly improved heat exchange efficiency and can significantly improve the energy efficiency ratio of the chillers. Therefore, the development of flooded chillers has increasingly become a hot topic in the field of large domestic chiller technology. Especially after the national new energy-saving evaluation standard for chillers was announced, it has become the focus of competition among large central air-conditioning manufacturers. The technical difficulty of flooded chillers lies in the oil return technology, so a high-performance oil-gas separator is crucial for flooded chillers.
[0003] The existing oil-gas separators have a small pipe diameter. The exhaust pipe and the oil drain pipe are fixedly connected to the exhaust system and the oil drain system respectively, and cannot be modified adaptively as needed. Moreover, the oil cannot be completely discharged from the oil-gas separator smoothly, and it is easy to stay and deposit. Regular discharge is likely to cause oil sediment. If the exhaust is too small, the oil in the oil-gas mixture cannot be discharged in time, thus accumulating in the pipeline and having a high risk of blockage. Insufficient exhaust will cause the oil-gas separator to be unable to effectively separate oil and gas, with low separation efficiency. A small exhaust volume may cause the system back pressure to rise, affecting the normal operation of the oil-gas separator and even possibly causing additional pressure on upstream equipment. And if the oil in the oil-gas mixture cannot be discharged smoothly, it may cause accelerated wear of internal components of the equipment (such as valves, pumps, etc.). Poor exhaust will increase the maintenance frequency and difficulty of the oil-gas separator, thus increasing the maintenance cost. Summary of the Utility Model
[0004] The utility model provides an oil-gas separator, aiming to effectively separate the gas and oil in the oil-gas mixture, improve the separation efficiency and reduce the blockage risk.
[0005] To achieve this purpose, the utility model adopts the following technical solutions:
[0006] An oil-gas separator includes an oil-gas separator body. A vertical through connection of an exhaust pipe and an oil drain pipe is provided on the side wall of the oil-gas separator body. A third fixing ring is sleeved on the free end of the exhaust pipe. A second fixing ring is clamped on the outer wall of the third fixing ring, and a threaded groove is provided in the inner cavity of the second fixing ring. The free end of the oil drain pipe is sealed by a sealing bolt. A docking pipe is vertically and through-connected to the top of the oil-gas separator body. A first fixing ring is connected to the free end of the docking pipe, and a number of fixing holes are provided on the first fixing ring.
[0007] Furthermore, handles are symmetrically provided on the side wall of the oil-gas separator body.
[0008] Furthermore, the outer diameter of the third fixing ring is larger than the outer diameter of the exhaust pipe.
[0009] Furthermore, the second fixing ring and the third fixing ring are snap-connected through a boss provided at one end of the inner cavity of the second fixing ring.
[0010] Furthermore, the exhaust pipe and the drain pipe are arranged vertically and collinearly.
[0011] Furthermore, the drain pipe is provided at one side of the bottom of the oil-gas separator body.
[0012] Furthermore, the number of fixing holes is six, which are respectively equidistantly arranged on the outer ring of the first fixing ring.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows;
[0014] The oil-gas separator provided by the present utility model fixes the exhaust pipe on the oil-gas separator body through the third fixing ring and the second fixing ring to prevent air leakage, and the inner cavity of the exhaust pipe is provided with a threaded groove, which is convenient for detachably connecting different exhaust components, and has strong practicability. The separated oil liquid is collected into a storage container through the drain pipe, which is convenient for subsequent treatment or recycling. Moreover, the drain pipe is provided at the bottom of the oil-gas separator body to ensure that the oil liquid separated by the oil-gas separator body can be smoothly discharged, reduce the retention of the oil liquid inside the oil-gas separator body, prevent sediment blockage, and improve the separation efficiency and safety. In addition, the sealing bolt is tightly matched with the drain pipe through threaded connection, which can not only effectively prevent the oil liquid from leaking during the discharge process, but also allow users to conveniently carry out inspections and maintenance to ensure the long-term safe and stable operation of the equipment.

[0021] The present utility model will be further described below in conjunction with the accompanying drawings:
[0022] As Figures 1-5 shown, the present utility model is an oil-gas separator, which includes a cylindrical oil-gas separator body 1. A vertically penetrating and communicating exhaust pipe 6 and an oil drain pipe 10 are vertically and collinearly arranged on the side wall of the oil-gas separator body 1, and the oil drain pipe 10 is arranged on one side of the bottom of the oil-gas separator body 1. The exhaust pipe 6 is used for discharging gas, and the oil drain pipe 10 is used for discharging oil. A third fixing ring 8 is sleeved and fixed at the free end of the exhaust pipe 6. The outer diameter of the third fixing ring 8 is larger than the outer diameter of the exhaust pipe 6. A second fixing ring 7 is clamped on the outer wall of the third fixing ring 8. The second fixing ring 7 and the third fixing ring 8 are combined to fix the exhaust pipe 6. Specifically, the second fixing ring 7 is clamped with the third fixing ring 8 through a boss arranged at one end of the inner cavity of the second fixing ring 7, and a thread groove 9 is arranged in the inner cavity of the second fixing ring 7 for connecting a safe and compliant exhaust system. The free end of the oil drain pipe 10 is sealed by a sealing bolt 11 connected by threads to prevent oil leakage. A docking pipe 3 is vertically penetrating and communicating at the top of the oil-gas separator body 1. The docking pipe 3 is used for connecting an oil inlet pipe. The free end of the docking pipe 3 is connected with a double-layer first fixing ring 4. Six fixing holes 5 are equidistantly arranged on the outer ring of the first fixing ring 4 for connecting and installing other oil inlet components. Two handles 2 are symmetrically arranged on the side wall of the oil-gas separator body 1 to facilitate the operation and holding of the oil-gas separator body 1.
[0023] Before using the oil-gas separator body 1 of the present application, first check to ensure that all the pipes connected to the oil-gas separator body 1 are intact, the connections are tight and there is no leakage. Place the oil-gas separator body 1 in a stable position. If power is required, connect the power supply in accordance with electrical safety specifications, check for abnormal sounds and vibrations, and ensure normal operation. Then, convey the oil-gas mixture into the oil-gas separator body 1 through the docking pipe 3. After the oil-gas separator body 1 effectively separates the oil-gas mixture, the separated gas is discharged through the exhaust pipe 6 to a safe and compliant exhaust system, and the separated oil is collected into a storage container through the oil drain pipe 10 for subsequent treatment or recycling. During use, regularly inspect and clean the exterior and interior of the oil-gas separator body 1 to avoid blockage caused by long-term use and ensure its efficient operation.
