Description

Novel tangential flow type gas-liquid separator

Technical Field

The utility model relates to a gas-liquid double-phase separation field can be used to the novel vapour and liquid separator of natural gas dehydration.

Background

Natural gas is transported in pipelines, often accompanied by condensation or reverse condensation phenomena, as the temperature and pressure vary. When condensation occurs, condensate water and oil condensate appear in the tubes, which, under the impact of the high-velocity gas stream, form tiny droplets in the tubes and are entrained in the gas phase. These liquid phase particles can cause the rotating components to fail, causing the compressor and turbine to fail. Meanwhile, the liquid drops can combine with chloride ions in natural gas and carbon dioxide and sulfide in air, and acidic substances are formed to corrode metal equipment such as pipelines and compressors. If the natural gas contains water drops and liquid light hydrocarbon, the sealing effect of the compressor can be influenced, and the blockage of a pressure regulator of a gas system can be caused. Therefore, in order to ensure the service life and normal operation of the gas transmission equipment, the gas-liquid separation of the natural gas is needed.

Disclosure of Invention

The utility model relates to a gas-liquid double-phase separation field is a novel vapour and liquid separator to natural gas dehydration.

The novel gas-liquid separator comprises a tangential inlet, a rotational flow cavity, a bracket, an outlet, an inertia separation pipe, a gas return pipe, a liquid collection tank, a liquid level pipe and a liquid discharge valve.

The gas-liquid separator can separate the gas-liquid mixture twice through the cyclone cavity and the inertia separation pipe. The gas-liquid mixture enters from the tangential inlet at the top of the cyclone cavity, and because the gas-liquid mixture can rotate and flow along the inner wall of the cyclone cavity due to inertia, liquid drops move towards the side wall under the action of centrifugal force in the flowing process, and the gas can flow at the center of the cyclone cavity and reach the outlet through a pipeline extending into the cyclone cavity to be discharged. The liquid collected at the bottom of the cyclone cavity flows into the liquid collecting tank through the inertia separation pipe and is discharged. The liquid level pipe is installed in the outside of collection liquid jar, can survey the interior liquid level condition of collection liquid jar through the liquid level pipe. The liquid discharge valve can control the liquid level in the liquid collection tank, so that the liquid after being discharged and separated can be ensured, the liquid sealing effect in the liquid collection tank can be realized, and gas discharge is prevented. When part of the gas-liquid mixture flows through the inertia separation pipe, liquid drops impact the semicircular baffle plate in the inertia separation pipe due to inertia to be captured, and the gas flows back to the outlet.

Preferably, the novel gas-liquid separator as described above is characterized in that: the gas-liquid separator is mainly made of metal materials, the tangential inlet, the tangential outlet, the cyclone cavity, the inertia separation pipe and the like are connected in a welding mode, and the drain valve is connected in a threaded mode.

Preferably, the novel gas-liquid separator as described above is characterized in that: the separator is fixed on the bracket for use, so that vibration in the operation process of the equipment is prevented.

The invention comprehensively utilizes the cyclone separation and inertia separation technology, solves the problem of gas-liquid separation, has strong practicability, can improve the separation efficiency by completing the gas-liquid separation in two separation processes, and has low energy consumption and low cost.
