Problems solved by technology
As the initial momentum absorbing baffle tilts forward, the fluid impacts the liquid phase along the tilt angle to form a low-pressure area, so that the liquid that has been separated from the gas is rolled up by the gas and splashed out of the liquid phase to form bubbles, such as figure 2 As shown, this is the so-called "re-entrainment" problem of bubbles; and because there is no flow stabilization device in the gas phase area, the flow state in the gas phase area is complicated, which affects the separation efficiency
[0004] In addition, the existing gas-liquid separator adopts a special short-circuit for installing the demist separation element on the upper part of the cylinder of the separator, and a short-circuit of the sewage outlet is also provided on the lower part of the cylinder, which increases the vertical height and cannot meet the requirements. Heating separation integration skid-mounted integration transportation requirements, so it is necessary to further improve the structure of the demister separation element to improve efficiency, and built into the separator cylinder
[0005] In short, the existing horizontal gas-liquid separator cannot meet the requirements of high precision, large flow and integrated skid-mounted device

The invention discloses a combined type natural gas-liquid separator. The combined type natural gas-liquid separator comprises a separator shell, and a natural gas inlet, a natural gas outlet and a liquid outlet which are arranged on the separator shell, wherein a gas-phase region and a liquid-phase region are arranged on the upper part and the lower part in the separator shell respectively; a primary cyclone separation device is arranged at the natural gas inlet; a rectifier is arranged in the middle of the gas-phase region; and a separation component is arranged at the natural gas outlet. The combined type natural gas-liquid separator has the advantages of doubling precision of the separator, effectively shrinking the diameter of a separator cylinder, reducing height of the separator, for the separation component is arranged in the cylinder, reducing manufacturing cost of the separator and meeting requirements of high precision and large flow.
Description
technical field [0001] The invention relates to a natural gas purification device, in particular to a natural gas horizontal gas-liquid separation device. Background technique [0002] The natural gas gas-liquid separator requires that the volume of the separator should be reduced as much as possible, and the processing capacity should be as large as possible. Generally, the minimum natural gas processing capacity of the gas-liquid separator used in the natural gas gathering and transportation system is 10×10 4 m 3 / d or more, separate 5m of stream water and condensate entrained in natural gas 3 / d~100 m 3 / d or so, more than 90% of the particles with a gas-liquid separation accuracy of 20-100 μm. [0003] Such as figure 1 As shown, the existing natural gas horizontal gas-liquid separator is composed of: air inlet 101, initial momentum absorption baffle 102, liquid phase area 103, gas phase area 104, defogging separation element 105, outlet 106, sewage outlet 107, etc. ...
