Further, a certain initial oil level is set in the oil-gas separation barrel from the very beginning, considering that the oil droplet particles (which can be understood as dirty oil) after the primary oil-gas separation will also fall to the first barrel under the action of gravity The bottom of the body 10, further, a second oil outlet 39 is set at the bottom of the first cylinder 10, wherein, in order to facilitate the collection of falling oil droplets, for this reason, the first cylinder 10 The bottom of the first cylinder 10 can be set as an inclined structure, and the inclined structure here can be set as a V-shaped or U-shaped structure, so that the oil droplets can continuously flow to a lower position at the bottom of the first cylinder 10 . In addition, the second oil outlet 39 can be arranged on the inclined structure, and the second oil outlet 39 here can be arranged at a lower position on the inclined structure, so as to facilitate later discharge at the position of the inclined structure. Describe the oil at the bottom of the first cylinder 10.

An oil inlet 40 is provided at the bottom of the second cylinder 20, and the oil inlet 40 is connected to the second oil outlet 39 through a second pipeline 41, where the oil at the bottom of the first cylinder 10 is and the oil at the bottom of the second cylinder 20 can flow, so that the oil level in the first cylinder 10 is consistent with the oil level in the second cylinder 20 . In this way, the oil that has undergone primary oil-gas separation in the first cylinder 10 is mixed with the lubricating oil contained in the first cylinder 10 and flows into the second cylinder 20 through the second pipeline 41 to form a certain oil level. The oil in the second barrel 20 with a certain oil level can enter the filter device 23 from the side of the filter device 23 to be filtered, and the filtered oil is discharged through the first oil outlet 32 .

Considering that the oil in the first cylinder 10 will flow into the second cylinder 20 and form a certain oil level in the second cylinder 20; further, the separation device 21 is set Above the oil level and the filter device 23 is set below the oil level. Specifically, considering that the oil droplets separated by fine oil and gas flow into the filter device 23 through the sleeve 22, the length of the sleeve 22 here can be adjusted as required, so that the filter device 23 can All are immersed below the oil level of the second cylinder 20, and the separation device 21 will not be in the oil, so as to prevent the separation device 21 from sucking lubricating oil and thus affect the separation efficiency of the separation device 21, and the oil plays a role Seal the action of clean air and dirty air. Of course, the sleeve 22 here can be reused, and the sleeve 22 of different lengths can be replaced according to, for example, the oil level, and only the separation device 21 needs to be connected with one end of the sleeve 22 during installation.

If the oil level is greater than the first preset threshold, that is, the oil level is too high, the separation device 21 will be saturated , which will cause the separation device 21 to fail to operate resulting in high oil carryover; if there is not enough clean oil drained and returned to the front end compressor for lubrication when the oil level is below a second preset threshold, It will cause the overall compressor system to fail to operate normally; and dirty air may flow into the clean air side through the oil filter, so that the clean air discharged from the air outlet 34 still has oil residue.

In order to prevent the oil level in the second cylinder 20 from being too high and causing the separation device 21 to saturate, the oil that has undergone fine oil-gas separation can also continuously flow back into the first cylinder 10 through the second pipeline 41 . For this reason, further, the position of the oil inlet 40 in the vertical direction is higher than the position of the second oil outlet 39, so as to ensure that the oil at the bottom of the second cylinder 10 here can pass through the The second pipe 41 flows toward the bottom of the first cylinder 10 . Here, oil is prevented from being pushed into the clean air side above the second cylinder 20 by controlling the pressure drop over the separating device 21 and the filtering device 23 .
