The oil-water separating seat 14 has an inner cavity formed therein, and an air inlet 141 is formed on an outer side surface thereof, and the inner cavity is communicated with the air inlet 141 and the lower air pipe 13. The oil-water separator 15 is located in the inner cavity, and as shown in fig. 4, the oil-water separator 15 includes a separator housing 151 and a multi-layer wire mesh 152 filled in the separator housing 151, a plurality of through holes are opened on the separator housing 151, and the air flow enters the separator housing 151 from the air inlet 141 to contact with the wire mesh 152 for oil-water separation, and then enters the adsorption tube assembly 12.

The oil-water separator 15 is arranged at the air inlet 141 of the adsorption separation device 100, so that the gas flow to be separated is firstly subjected to oil-water separation before entering the adsorption pipe assembly 12, and the oil is prevented from polluting the adsorbent in the adsorption pipe assembly 12. Because the multiple layers of wire meshes are arranged in the separator shell 151, the contact time of the air flow and the wire meshes 152 can be prolonged, the air flow can be in full contact with the wire meshes 152, and the oil in the air flow is condensed into liquid oil to be separated, so that the aim of fully removing the oil in the air flow is fulfilled.

It is to be understood that the configuration of the sorbent tube assembly as shown in fig. 7 is merely an exemplary configuration and that the configuration of the sorbent tube assembly 12 can be other configurations that perform similar or analogous functions.

As shown in fig. 2 and 3 in conjunction, the rear end portion of the lower air duct 11 is further provided with an air inlet valve seat 17, and the air inlet valve seat 17 extends from the leftmost end to the rightmost end of the lower air duct 11 to cross each lower air chamber. More than one air inlet valve assembly 16 is arranged on the air inlet valve seat 17, and the air inlet valve assembly 16 is correspondingly arranged in each lower air cavity 131 so as to control the flow direction of the air flow of each lower air cavity 131 or the air flow flowing to each lower air cavity 131.

Since the first group of adsorption tubes 12a and the second group of adsorption tubes 12b of the adsorption tube assembly 12 alternately perform adsorption work and regeneration work, the control cylinder 161 controls the exhaust pressure plate 1624 to open the communication port between the lower air chamber of the lower air tube and the exhaust valve chamber while controlling the intake pressure plate 1622 to close the communication port between the lower air chamber of the lower air tube and the intake valve chamber. On the contrary, when the control air cylinder 161 controls the air inlet pressure plate 1622 to open the communication port between the lower air cavity of the lower air pipe and the air inlet valve cavity, the control air exhaust pressure plate 1624 simultaneously closes the communication port between the lower air cavity of the lower air pipe and the air exhaust valve cavity. Therefore, the lower air cavity corresponding to the adsorption working group is used for air intake, the lower air cavity corresponding to the regeneration working group is used for air exhaust, and switching between air intake and air exhaust is achieved.

In the present disclosure, the air inlet valve seat and the oil-water separation seat are located at the rear end, and the opposite direction is the front end. Accordingly, the left-right direction is perpendicular to the front-back direction.

After the adsorption core 122 of the first group is adsorbed and saturated, switching is performed, that is, the adsorption core 122 of the second group is adsorbed, and the adsorption core 122 of the first group is desorbed and regenerated, so that the two groups of adsorption cores are alternately adsorbed and regenerated.
