Description

Technical Field

[0001] The utility model relates to the technical field of oil-gas separators, in particular to a liquid separation net structure of an oil-gas-liquid separator. Background Art

[0002] The oil-gas separator is one of the important components of the entire submersible electric pump system. Its function is first to serve as the suction port for oil and gas to enter the multi-stage centrifugal pump; secondly, before the mixed gas liquid enters the multi-stage centrifugal pump, the separator separates the free gas from the well fluid, thereby reducing the impact of the gas on the working characteristics of the submersible electric pump, preventing the centrifugal pump from cavitation and gas lock, and enabling the multi-stage centrifugal pump to work normally. The oil-gas separator is generally installed at the breathing port of the engine crankcase or the exhaust pipe. As the name suggests, its function is to separate the oil in the crankcase exhaust gas and reduce the oil discharged from the crankcase breathing port to the outside of the engine.

[0003] When the existing oil-gas separator is performing gas-liquid separation, if the liquid isolation net structure in the oil-gas separator is blocked or excessive liquid is adsorbed, it needs to be cleaned and replaced, thereby reducing the utilization rate of the liquid isolation net structure.

[0004] According to the announcement number: CN217501995U, a simple oil-gas separator is proposed, including: a shell, on which an air inlet pipe and an exhaust pipe are arranged, a plurality of partitions, the plurality of partitions are arranged inside the shell, and the interior of the shell is divided into a plurality of cavities connected end to end, and a baffle condensation plate, the baffle condensation plate is arranged in the cavity, and the cavity is divided into a plurality of sub-cavities connected end to end. The simple oil-gas separator has high gas-liquid separation efficiency and a long service life, and can solve the problems of insufficient gas-liquid separation rate and easy clogging of the mesh in the existing traditional gas-liquid separator.

[0005] According to the above introduction, the liquid partition net structure of the oil-gas-liquid separator will absorb a large amount of liquid when in use. When the liquid adsorbed by the liquid partition net structure is saturated, the adsorption of liquid in the gas is reduced, thereby reducing the gas-liquid separation effect. At the same time, the saturated liquid partition net structure needs to be replaced by the staff. In order to solve the above problems, an improved liquid partition net structure of an oil-gas-liquid separator is proposed. Utility Model Content

[0024] The liquid isolation assembly 7 includes a fixed frame 71 and a movable frame 72. The fixed frame 71 is fixed to the inner cavity of the tank body 1. An adsorption cotton plate 73 is placed on the fixed frame 71. The upper surface of the adsorption cotton plate 73 is in contact with the lower surface of the movable frame 72. The upper surface of the movable frame 72 is fixedly connected to the adjustment mechanism 6. The inner side walls of the fixed frame 71 and the movable frame 72 are both installed with a wire mesh 74.
