Description

Technical Field

[0001] This application relates to the field of gas-liquid separation technology, and in particular to a gas-liquid separation device. Background Technology

[0002] Gas-liquid separation is a process that utilizes the differences in physical properties such as density and inertia between gas and liquid to effectively separate the mixed gas and liquid phases through methods such as gravity settling, inertial collision, centrifugal force, or filtration. Its purpose is to purify gas, recover valuable liquids, reduce equipment corrosion, or ensure the normal operation of subsequent processes. It is widely used in petrochemical, energy and environmental protection, and pharmaceutical fields.

[0003] Among them, gravity-sedimentation-based gas-liquid separators are simple devices that utilize the density difference between gas and liquid phases to achieve natural separation through gravity. They are widely used in preliminary or low-precision separation of gas-liquid mixtures. Their core structure is a vertical or horizontal pressure vessel, typically without complex internal components. During operation, the gas-liquid mixture flows into the tank, and the flow velocity decreases due to the sudden expansion of the space. Because the liquid is much denser than the gas, it gradually settles to the bottom of the tank under gravity and is discharged through the drain port, while the gas flows out through the top outlet. Existing gravity-sedimentation-based gas-liquid separators suffer from short separation times and poor separation efficiency. Utility Model Content

The third flange 51 and the fourth flange 52 are connected by the second fastener 53. Optionally, the second fastener 53 is a screw or bolt, etc. Similarly, since it is inconvenient to drill holes in the quartz tank, a protrusion can be provided on the quartz tank to cooperate with the third flange 51 and the fourth flange 52, so as to restrict the movement of the third flange 51 and the fourth flange 52 in the axial direction of the tank, thereby ensuring that the third flange 51 and the fourth flange 52 can be fastened by the second fastener 53.

When the gas-liquid phase material enters the gas-liquid separation chamber 11, the liquid phase product is rapidly dispersed within the annular distribution grooves 22 and connecting grooves 24. After the liquid level in the annular distribution grooves 22 is higher than the overflow hole 23, the liquid phase product simultaneously overflows from the multiple overflow holes 23 into the packing chamber 12, ensuring that the liquid phase product is uniformly sprayed onto the packing 30, improving the utilization rate of the packing 30, and increasing the gas-liquid separation time and efficiency. Exemplarily, the number of annular distribution grooves 22 can be two, three, four, or five, etc.; the number of connecting grooves 24 can also be two, three, four, or five, etc., and is not specifically limited.
