Working principle and application scope of liquid gas separator?

　　The liquid gas separator is a special equipment for primary degassing of gas cut drilling fluid. It is a good mud gas separator. According to the pressure, the liquid gas separator can be divided into two types: normal pressure type and pressure self-control type.
　　The liquid gas separator is made of normal pressure anti hydrogen sulfide drilling fluid. It can effectively prevent the erosion of harmful gas and ensure man-machine production. When the drilling fluid produces gas invasion, its specific gravity and viscosity deviate greatly, which can not meet the drilling requirements; in serious cases, if it is not handled in time, it will cause well kick and even blowout accident. The combination of liquid gas separator and electronic ignition device can ensure the smooth drilling process.
　　The liquid gas separator is used with choke manifold to separate free gas from drilling fluid, and can be used in underbalanced drilling and drilling fluid treatment containing hydrogen sulfide gas. Traditional control of liquid level and pressure of separator.

　　characteristic
　　1. The liquid gas separator adopts the bottom drainage to control the working liquid level, so as to ensure the constant liquid level in the separator and solve the problem of sand accumulation in the tank;
　　2. A special gas separation channel is set in the liquid gas separator tank to ensure smooth gas evacuation and improve the gas treatment effect;
　　3. The liquid-gas separator adopts centrifugal separation, physical impact separation, vacuum separation and other separation technologies to ensure the gas separation effect;
　　4. Buffer devices are installed at each corner of the liquid supply pipe of the liquid-gas separator, and replaceable impact resistant baffles are installed, which can be inspected and replaced regularly according to the wear condition, thus prolonging the service life of the equipment;
　　5. The anti sulfur liquid gas separator of liquid gas separator is made of special materials, which can completely prevent the equipment from being damaged by hydrogen sulfide in the gas.
　　working principle
　　The gas cut drilling fluid of the liquid gas separator enters the separator from the tangent line of the liquid inlet of the separator and falls on a series of specially designed inner baffles along the inner wall. It collides and exposes the surface area and flows downward, resulting in turbulent flow and separating the gas from the drilling fluid. The free gas is discharged through the gas outlet on the top of the tank, the length of the exhaust pipe is determined and equipped on site, and it is led everywhere, and the degassed drilling fluid is discharged into the circulating tank.
　　When the liquid gas separator is not in use, the drilling fluid in the equipment shall be drained and washed with water. It is strictly forbidden to store the mud in the separator to prevent the mud from being used normally after it is dry and solid.
