The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] The specific usage scenario of this embodiment is: the centrifugal separation unit includes a centrifuge body: this is the core component, which is used to generate centrifugal force, a drum: a container for placing materials to be separated, a driving device: driving the drum to rotate at high speed, a feed pipe: for material entry, and a discharge port: including discharge channels of different components. The working principle of the centrifugal separation unit is that the drum is rotated at high speed by a driving device. After the material enters the drum, under the action of a strong centrifugal force, materials of different densities or particle sizes will be layered or separated due to different centrifugal forces. Materials with higher density will be thrown to the drum wall, while materials with lower density will be close to the center of the drum, thereby achieving the purpose of separation. The double-bag blade separation unit is a gas-liquid separation device. When liquid-containing gas enters the double-bag blade separation unit, the airflow will form a complex flow path between the blades. The design of the blades causes the airflow to turn and accelerate multiple times during the flow process, so that the liquid particles collide and agglomerate with the blade surface under the action of inertial force. The agglomerated liquid flows downward under the action of gravity and gathers at the bottom of the separator to form a liquid collection area. The gas continues to flow upward through the gaps between the blades and is discharged from the outlet of the separator. The metal membrane separation unit is a device that uses a metal membrane to separate substances. Its main structure includes a metal membrane, a membrane assembly, a feed system, a discharge system, and a control system. The metal membrane is the core component of the metal membrane separation unit. It is usually made of metal materials and has good electrical conductivity, thermal conductivity, and corrosion resistance. The pore size and distribution of the metal membrane can be designed and prepared according to different separation requirements, thereby achieving selective separation of different substances. The working principle of the metal membrane separation unit is to use the selective permeability of the metal membrane to separate the substances to be separated through the metal membrane. In the metal membrane separation unit, the substances to be separated enter the metal membrane separation unit under the action of the feed system, and then a certain pressure difference is formed on both sides of the metal membrane, so that the substances to be separated penetrate and diffuse on both sides of the metal membrane. Since the pore size and distribution of the metal membrane can be designed and prepared according to different separation requirements, only substances that meet the pore size and distribution requirements of the metal membrane can pass through the metal membrane, thereby achieving selective separation of different substances;
[0024] The cavity-type pressurized self-flushing unit uses 60-80℃ hot water to enter the cavity from the top of the blade, and after the pressure is increased to a certain level in a smaller cavity space, it flushes downward vertically with the airflow direction. The high temperature and pressure of the flushing water are used to fully cover the entire blade filter surface, dissolving and removing the condensed paraffin on the blade filter surface, thereby achieving the purpose of online wax removal.
[0025] Example 2: Figure 1 and Figure 2The spray pipe 200 is fixedly installed on the inner wall of the reactor 100. The input end of the spray pipe 200 is fixedly connected to the first water inlet pipe (not marked in the figure) through the first flange 210. The spray pipe 200 is made of high-temperature resistant metal. The cleaning liquid transported inside the spray pipe 200 is clean water with a temperature of 80°C. The output end of the funnel pipe 230 is close to the blade surface of the double-bag blade separation unit.
[0026] The specific usage scenario of this embodiment is: by setting up a spray pipe 200 to distribute 80° C. clean water to the atomizer 220, the atomizer 220 atomizes the clean water and increases the pressure to improve the flushing effect.
[0027] Example 3: Figure 1 and Figure 3-4 The adjacent water injection pipes 300 are staggered left and right, the input end of the water injection pipe 300 is connected to the second water inlet pipe through the second flange 310, the metal membrane separation unit includes a metal membrane 130, the water injection pipe 300 and the manifold 320 are made of high-temperature resistant metal materials, the water source inside the water injection pipe 300 is 80°C, and the manifold 320 is distributed one-to-one with the metal membrane 130 in the metal membrane separation unit.
[0028] The specific usage scenario of this embodiment is: by setting up a water injection pipe 300 for inputting cleaning liquid, the surface of the metal membrane separation unit is flushed with high temperature and high pressure to remove the wax adsorbed on the surface of the metal membrane separation unit, and by arranging the positions of adjacent water injection pipes 300 to be staggered left and right, it is convenient to flush the surface of the metal membrane separation unit evenly during flushing.
[0029] Example 4: Figure 1 and Figure 2 The bottom of the reactor 100 is set to be hemispherical, and the outer wall of the bottom of the reactor 100 is fixedly connected to the liquid outlet pipe 150. There are two liquid outlet pipes 150. The bottom end of the double-bag blade separation unit is fixedly connected to the feed pipe 122. The feed pipe 122 passes through the metal membrane separation unit to the outer wall of the bottom of the reactor 100.
[0030] The specific usage scenario of this embodiment is: a liquid outlet pipe 150 is provided to discharge the liquid and the separated wax inside the reaction kettle 100 .
[0031] Example 4: Figure 1 and Figure 2 The centrifugal separation unit includes a centrifugal separation unit body 110, the input end of the centrifugal separation unit body 110 is fixedly connected to a first feed pipe 111, and the first feed pipe 111 is fixedly installed on the inner wall of the reactor 100. The double-bag blade separation unit includes blades 120, and the input end of the double-bag blade separation unit is fixedly connected to a second feed pipe 121. The side wall of the reactor 100 is fixedly installed with a first exhaust pipe 140, and the top outer wall of the reactor 100 is fixedly installed with the first exhaust pipe 140.
[0032] The specific usage scenario of this embodiment is: by setting a first feed pipe 111 to transport the synthesis gas containing droplets and paraffin to the interior of the centrifugal separation unit, by setting a double-bag blade separation unit to separate larger particle droplets by utilizing centrifugation, inertial collision, and gravity sedimentation.
[0033] The working principle of the utility model is as follows: when used by technicians in this field, the synthesis gas containing liquid droplets and paraffin is transported to the centrifugal separation unit through the first feed pipe 111, and the synthesis gas containing liquid droplets and paraffin is roughly separated into large-size droplets through the centrifugal separation unit, and then the gas is passed through the double-bag high-efficiency blade separation unit in the middle air intake and air outlet on both sides, and the larger particle droplets are separated by centrifugation, inertial collision, and gravity sedimentation, and finally the gas enters the metal membrane separation unit from the outside and exits from the inside, and the separated and purified gas enters the subsequent compression and supercharging process, and the intercepted paraffin is attached to the separation element, resulting in The pressure difference of the separation device rises, and the chamber-type pressurized self-flushing unit and the candle-type grouped online cleaning unit are opened in turn, so that the wax adsorbed on the surface of the double-bag blade separation unit and the metal membrane separation unit is flushed with 80°C high-temperature clean water. By increasing the pressure of the 80°C high-temperature clean water, the flushing force is increased, thereby accelerating the speed of wax removal. After being flushed, the wax is discharged through the discharge pipe 122, and then falls to the bottom of the reactor 100 and is discharged through the liquid outlet pipe 150. The gas is discharged through the exhaust pipe 160 at the top of the reactor 100 and collected for the next process.
