The effect of this scheme is: (1) the separation efficiency is improved: the velocity of the air flow into the neck increases due to the smaller cross section of the neck. This increase in air flow rate can be a filtering effect of the cartridge. The oil particles entering the filter element fiber layer are intercepted by virtue of motion inertia, and collide with each other or the oil particles collide with the multi-layer limiting filter element, so that the particles gradually increase to become liquid, the airflow speed is increased, the particles have larger motion inertia, the filtering efficiency of the filter element can be effectively improved, and the oil mist separation efficiency is enhanced. (2) Space occupation is reduced: the cross section of the neck is smaller, and compared with the whole tank body, the oil mist separator occupies smaller space, so that the whole structure of the oil mist separator is more compact, and the oil mist separator occupies smaller installation space. This compact design can better accommodate practical application requirements, particularly in limited mounting environments.

The effect of this scheme is: the filter element is convenient to maintain and replace, and as the filter element is arranged in the neck, maintenance personnel can open or close the space in the neck through the flange plate, and access and replace the filter element conveniently. The whole tank body is not required to be disassembled or moved, and the maintenance operation of the filter element can be easily performed by only opening the access port of the neck. This saves time and labor and improves maintenance efficiency.

Further, the tank body is also connected with a first pressure gauge, and the first pressure gauge is connected with the first cavity.

Further, the tank body is also connected with a second pressure gauge, and the second pressure gauge is connected with a second cavity.

The effect of this scheme is: through the connection of manometer, the pressure condition of each cavity of oil mist separator can be monitored, in time discover abnormal conditions, if pressure is too high to avoid causing harm or security risk to the system. In particular, the difference between the pressure value of the first pressure gauge and the second pressure gauge may indirectly reflect the condition of the filter element. As the filter element gradually blocks or accumulates oil mist, the resistance of the filter element increases, resulting in a pressure rise in the second chamber, thereby increasing the pressure difference between the first and second pressure gauges. The device can be used as an index of the condition of the filter element to remind an operator to maintain or replace the filter element.
