AI Technical Summary
As the diameter of existing large separators increases, the required clearance height also increases, leading to increased weight and cost. Furthermore, the separation efficiency is low, which can easily cause localized damage, and the separation effect of fixed baffles and/or guide plates is not good.
The system employs a volute separator, consisting of a cylinder and conical spirally stacked guide vanes. Combined with turbine-enhanced centrifugal force, it performs primary, secondary, and tertiary gas-liquid separation. The gas-liquid separation is further optimized by guide arc plates and cylindrical wire mesh. A rationally designed gas-liquid mixing inlet box and liquid seal structure are used to achieve uniform distribution and efficient separation of the gas-liquid mixture.
It reduces the required clearance height, decreases weight and cost, improves gas-liquid separation efficiency, avoids rapid turning and mutual impact, and achieves a highly efficient gas-liquid separation effect.

[0005] 2) With the increasing complexity of the structure of the separator and the increasing size, the weight of the distributor itself is also increasing, and the stress under the impact of the gas is also increasing, which will cause the increase of the external load. Moreover, the manufacturing and installation of the above large distributor requires high precision, and once there is a difference in the circumferential gap or the central shaft of the guide plates of each layer is different from the center of the equipment, the airflow will be deflected, which not only cannot guarantee the uniform distribution of the airflow, but also easily causes local damage problems, reduces the service life of the equipment and affects the safe operation of the equipment.

[0015] The further improvement of the above technical solution is that the separator further includes a gas-liquid mixed inlet box, which is installed in the body, and each volute separation cylinder is fixed on both sides of the gas-liquid mixed inlet box and arranged along the gas-liquid mixed inlet box, the inlet of which is opposite to and communicated with a plurality of outlets arranged on both sides of the gas-liquid mixed inlet box, and the gas-liquid mixed inlet is opposite to and communicated with the inlet arranged at one end of the gas-liquid mixed inlet box. The gas-liquid mixture is evenly distributed to each volute separation cylinder through the gas-liquid mixed inlet box.
[0016] The further improvement of the above technical solution is that the gas-liquid mixed inlet box is inclined, with the inlet side end being high and wide, and the non-inlet side end being low and narrow. The gas-liquid mixture is more evenly distributed. The non-inlet side end of the gas-liquid mixed inlet box is provided with a liquid discharge port, and the liquid discharge port is provided with at least one level of liquid seal. It is used to drain the liquid in the gas-liquid mixed inlet box.
[0017] The further improvement of the above technical solution is that the volute inlet of each volute separation cylinder is provided with a front guide arc plate. The gas-liquid mixture is further evenly distributed.
[0018] Further improvement is made to the above technical scheme, the gas outlet is a circular tube passing through the top of the device body, and a cylindrical wire mesh is arranged on the outer periphery of the device body.
