[0004] For example, the prior art patent CN202110942982 can improve the separation efficiency of oil and gas, but it still has some disadvantages. One of the disadvantages is that the device has a noise problem when used in a high-pressure environment. The noise is high, especially under the condition of non-continuous pressure relief, which has a great impact on the surrounding environment. In addition, the device has a poor pollution discharge effect. This is because the separation effect and filtering effect of the oil and gas mixture are limited. After gas separation, there is an odor, and the gas with oil stains is easy to be sent to the cabin, causing environmental pollution. Especially in a high-pressure environment, the frequency is relatively high, and the cabin environment is seriously polluted. Even if the filter equipment is added to purify the outlet gas phase, it can avoid the pollution of the system to the cabin atmosphere environment, but it can only solve the problem periodically, and the filter core needs to be replaced frequently, which is costly.

[0033] ​​In this embodiment, the connecting head 3 is arranged on the liquid collecting tank 1, and has a gas passage for connecting the liquid collecting tank 1 and the gas collecting tank 2. The gaseous phase of the oil and sewage separated by the separation rod 5 is collected by the gas collecting tank 2, and the liquid phase of the oil and sewage separated by the separation rod 5 is collected by the liquid collecting tank 1. That is, the connecting head 3 in this scheme is similar to a tee structure, wherein the middle pipe opening corresponds to the sewage inlet 4 for matching and communicating with the sewage outlet of the air compressor, the pipe opening at the bottom of the sewage inlet 4 communicates with the liquid collecting tank 1, and the pipe opening at the top of the sewage inlet 4 communicates with the gas collecting tank 2. In use, the oil and sewage is separated into gaseous phase and liquid phase by the separation rod 5, and under the action of gravity, the gaseous phase of the separated oil and sewage escapes upward to the gas collecting tank 2, and the liquid phase flows downward to the liquid collecting tank 1. In this scheme, the oil and sewage collecting cavity is expanded by the upper and lower cavities during sewage discharge, which greatly reduces the sewage discharge pressure value and reduces the noise during discharge.

[0034] In this embodiment, the liquid collecting tank 1 and / or the connecting head 3 has an oil baffle 6 located at the rear side of the sewage inlet 4. The oil baffle 6 is used to further disperse the fluid form under high pressure, which on the one hand reduces the impact speed of the oil and sewage under high pressure, and on the other hand separates the liquid phase and the gaseous phase of the oil and sewage, reduces the impact howling under high pressure of the oil and sewage, and reduces the noise. It can better separate the sewage of the air compressor unit, overcome the noise problem of the device used in a high pressure environment, improve the sewage separation effect of the device used in a high pressure environment, and reduce the pollution of the separated gas to the cabin environment.

[0035] In this embodiment, the oil baffle 6 has a flow dividing surface facing the sewage inlet 4, which can further increase the contact area with the oil and sewage, and the structure facing the sewage inlet 4 can actively break and disperse the fluid, reduce the flow pressure, and cooperate with the large volume pressure reduction measures of the double tanks to greatly reduce the noise decibels, reduce the damage to hearing, reduce noise pollution, so as to no longer affect the surrounding environment and ensure the life of the personnel near the cabin.

[0036] In this embodiment, the flow dividing surface is a conical surface, and the tip of the conical surface faces the sewage inlet 4. This further improves the breaking and dispersing ability of the high pressure jet of the oil and sewage, and the structure further increases the flow area while having a guiding effect, which further ensures the orderly separation of the oil and sewage and improves the separation efficiency.

[0041] In this embodiment, the liquid outlet 10 is provided on the liquid collecting tank 1, and is located at the bottom of the oil baffle 6 and is provided with a valve controlled to be opened and closed. The separated liquid phase in the liquid collecting tank 1 is collected and treated through the liquid outlet 10 regularly, and is discharged regularly by PLC automatic control or manual control, which is convenient for maintenance. The connecting head 3 is sealingly arranged on the top of the liquid collecting tank 1 through a flange, and the activated carbon tank and the liquid collecting tank 1 are arranged in a coaxial and downward distribution manner, which saves the area occupied and has the ability to improve the tank volume and reduce the impact pressure.

[0042] In this embodiment, the filter head 11 is arranged between the liquid outlet 10 and the oil baffle 6. In this scheme, the central axis of the liquid outlet 10 coincides with the central axis of the liquid collecting tank 1, and the filter head 11 is in a circumferentially perforated cylindrical structure, and the oil baffle 6 is in a conical cover which is arranged at the bottom of the liquid collecting tank 1 together with the filter head 11, and the central axis of the filter head 11 and the central axis of the oil baffle 6 also coincide with the central axis of the liquid collecting tank 1, so that the filter head 11 surrounds the liquid outlet 10, the oil baffle 6 blocks the liquid outlet 10, and the peripheral edge of the flow dividing surface of the oil baffle 6 is close to the circumferential inner surface of the liquid collecting tank 1, which further ensures the breaking and dispersing ability of the airflow, and at the same time, the bottom of the liquid collecting tank 1 with the liquid outlet 10 forms a relatively low-pressure liquid storage space, and the liquid phase is all collected to this place, and is uniformly discharged and collected after the liquid phase is collected to a certain amount or a certain time of pollution, wherein the filter head can also select any one of the existing technologies to be applied in this scheme, which will not be described here.

[0043] In this embodiment, the filter core is arranged at one end of the air passage close to the liquid collecting tank 1, and the filter core is detachably arranged at the bottom of the air passage of the separation rod 5. The separated gas phase is sent to the gas collecting tank 2 through the filter core.
