What is the working principle of ZLCQ centrifugal degasser？
Time: 2023-07-24 Source: HL Petroleum Author: hlsolidscontrol
ZLCQ centrifugal degasser is a device used to remove gas in drilling fluid, and its working principle is based on the principle of centrifugal force and negative pressure.
1. Send the liquid-gas mixture (drilling fluid containing air bubbles) into the bottom of the degasser through the inlet.
2. When the motor drives the main shaft to rotate, the impeller at the bottom sends the gas-liquid mixture into the upper separation chamber of the degasser. In the separation chamber, the rotation of the separation blade drives the drilling fluid to form a rotating state.
3. A thin liquid layer about 2 to 3 cm thick is formed on the inner wall of the separation cylinder, which is in a vortex state and spirals upward.
4. The rotation of the liquid thin layer forms a centrifugal force field, which makes the gas and liquid phases separate rapidly. The air bubbles are pushed toward the axis by the centrifugal force, while the liquid clings to the inner wall of the separation cylinder.
5. When the bubbles reach the surface of the thin layer of swirling liquid, due to the negative pressure in the separation chamber of the degasser, the bubbles can quickly break through the surface tension of the liquid and burst. A vacuum pump then quickly draws the collapsed air bubbles out of the drilling fluid.
6. The degassed drilling fluid ascends spirally along the inner wall of the separation cylinder, and the degassed liquid is discharged from the liquid discharge port.
The ZLCQ centrifugal degasser separates and extracts the gas in the drilling fluid by using the principle of centrifugal force and negative pressure, so as to improve the quality and performance of the drilling fluid.
