Centrifugal degasser

1. Familiarization

The degasser is one of the main solid-state control devices in the process of oil drilling. Its main function is to, to separate the associated oil gas from the wellhead back into the mud, And the gas invaded the dirt. The efficiency and efficiency of deaerator separation are the main metrics for measuring equipment performance.
ZLCQ Centrifugal Degasser / 240 has the characteristics of large processing capacity, High separation efficiency and wide range of applications.

ZLCQ Centrifugal Degasser / 240 consists mainly of explosion-proof motor, electrical control unit, vacuum pump assembly, reducer and separator assembly for gas and gas separation. The design of the structure is reasonable, compact and superior in performance. The gas separator is equipped with a liquid gas separation blade to improve separation efficiency, A new type of suspension discharge device has been adopted, which greatly improves the performance of the whole machine.

• Principle of operation

When using the ZLCQ centrifugal degasser / 240 The liquid-gas separation cylinder is immersed in the drilling fluid. When the motor rotates the spindle, to rotate it, The mud immersed in water is first directed to the separation chamber above the damper at the bottom of the degasser, and the separating blade in the separating chamber rotates, to rotate the drilling fluid to rotate. A thin layer of liquid forms on the inner wall of the separation cylinder, having a thickness of about 2-3 cm in vortex state for spiral upward movement. A rotating layer of fluid forms a centrifugal force field, and therefore the gas phase splits rapidly. The bubble moves in the direction of the axis, and the liquid rests on the inner wall of the separating cylinder. When the bubble reaches the inner surface of a thin layer of swirling liquid, because negative pressure occurs in the separator chamber of the deaerator, The bubble can quickly break through the surface tension of the liquid and rupture, and is quickly removed by the vacuum pump. The degassed drilling mud is spirally lifted along the inner wall of the separating cylinder and discharged from the fluid outlet.

1. 1.2 Performance

ZLCQ Centrifugal Degasser / 240 Has a reasonable structure design, stable operation, Low noise level, Long uptime and reliable operation. It is suitable for gas-liquid separation of drilling fluids with various parameters. Mud viscosity range, to be processed, Is 20 °mum. 80-In the 1990s,.

1. 1.3 Structural features

• Using a Vacuum Pump, High exhaust efficiency.
  · Using Unique Reducer Design, Smooth and constant speed.
  · A long liquid gas separation separator is used to increase the separation stroke, And the gas-liquid separation efficiency is high.
  · The use of a new type of suspension device greatly improves the performance of drilling fluid.
