Description

Technical Field

[0001] The utility model belongs to the technical field of petroleum gas-liquid separation and relates to a liquid-gas separation device based on a baffle structure. Background Art

[0002] The baffled liquid-gas separator utilizes the different densities of gas and liquid, and sets baffles on the material flow path, so that the material directly collides with the baffles to achieve the function of separating gas and liquid. However, the existing baffled liquid-gas separators only rely on the collision between the baffles and the material to achieve liquid-gas separation, and the material obtained in the oil extraction process is viscous. It is difficult to fully separate the gas in the material by relying solely on the collision between the baffles and the material, resulting in the final separated liquid phase still containing gas.

[0003] Therefore, in view of the defect that the existing baffled liquid-gas separator cannot fully separate the gas in the material when dealing with relatively viscous materials, the utility model discloses a liquid-gas separation device based on a baffle structure. Utility Model Content

[0004] The purpose of the utility model is to provide a liquid-gas separation device based on a baffle structure, so that the baffle plate rotates. During the process of the baffle plate colliding with the material, centrifugal force is applied to the material at the same time to ensure that the material is fully stressed, thereby ensuring that the gas in the material is fully separated, thereby improving the liquid-gas separation effect.

[0005] The utility model is realized by the following technical solutions:

[0006] A liquid-gas separation device based on a baffle structure comprises a separation tank body, an exhaust pipe is arranged on the top of the separation tank body, a liquid discharge pipe is arranged on the bottom of the separation tank body, a gas-liquid separation bucket is coaxially arranged inside the separation tank body, a rotating fan blade is coaxially arranged on the top of the gas-liquid separation bucket, a liquid inlet pipe is arranged on the side wall of the separation tank body corresponding to the tangential direction of the rotating fan blade, a plurality of baffle structures are evenly distributed along the circumferential direction on the inner wall of the gas-liquid separation bucket, and a liquid channel is arranged at the bottom of the baffle structure.

[0007] The material to be separated enters the interior of the separation tank through the liquid inlet pipe, and washes the rotating blades along the tangent direction of the rotating blades, thereby driving the rotating blades and the gas-liquid separation bucket to rotate. After the material washes the rotating blades and slows down, it falls into the interior of the gas-liquid separation bucket and flows along the baffle structure on the inner wall of the gas-liquid separation bucket. At the same time, the rotation of the gas-liquid separation bucket applies centrifugal force to the material in the baffle process, so that the gas in the material is fully analyzed to achieve liquid-gas separation. The separated gas rises to the top of the separation tank and is discharged through the exhaust pipe, and the separated liquid falls to the bottom of the separation tank through the liquid channel and is discharged through the drain pipe.

[0008] In order to better realize the utility model, further, a swirl part is arranged between the top of the gas-liquid separation bucket and the bottom of the rotating fan blade, a swirl channel is arranged inside the swirl part, the inlet end of the swirl channel is arranged corresponding to the tangential direction of the rotating fan blade, and the outlet end of the swirl channel is arranged corresponding to the inlet end of the deflection structure.

[0009] In order to better realize the utility model, further, the baffle structure includes a plurality of baffles arranged in a staggered and inclined manner, and a plurality of air holes are arranged in an array on the baffles.

[0010] In order to better realize the utility model, further, the gas-liquid separation bucket is in the shape of a funnel that is larger at the top and smaller at the bottom, and a plurality of air holes are arranged on the inner wall of the gas-liquid separation bucket.

[0011] In order to better realize the utility model, further, the bottom of the gas-liquid separation bucket is circumferentially provided with a plurality of support rods extending to the bottom of the separation tank body, and the outside of the support rods is provided with stirring blades.

[0013] In order to better realize the utility model, further, the condensation part includes a plurality of condensation plates arranged staggered and inclined, and a plurality of air holes are arranged on the condensation plates.

[0014] In order to better realize the utility model, further, a rectifying flap is arranged inside the liquid inlet pipe.

[0015] In order to better implement the utility model, further, a booster pump is provided on the liquid inlet pipe.

[0016] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0017] The utility model arranges a gas-liquid separation bucket in a rotatable manner inside a separation tank body, and arranges rotating blades on the top of the gas-liquid separation bucket, inputs materials through a liquid inlet pipe arranged on the separation tank body along the tangent direction of the rotating blades, and drives the gas-liquid separation bucket to rotate by flushing the rotating blades through the materials, and simultaneously, when the materials flow through the gas-liquid separation bucket, the materials are baffled and impacted by the baffle structure, and the gas-liquid separation bucket rotates to apply centrifugal force to the materials, thereby ensuring that the materials fully impact, so that the gas in the materials is fully separated, thereby improving the liquid-gas separation effect.
