Abstract
Description
Technical Field
[0001] This utility model belongs to the field of separation equipment technology, and specifically relates to a solid-liquid-gas three-phase separator. Background Technology
[0002] A three-phase separator is a device used to separate mixtures of solid, liquid, and gas phases. It has wide applications in many fields such as oil and gas, wastewater treatment, and biofuel production.
[0003] Gravity sedimentation separation: Separation is achieved by utilizing the density differences of the three phases under the action of gravity.
[0004] Centrifugal separation principle: High-speed rotation generates centrifugal force, causing solid particles and liquids to move towards the container wall under the action of centrifugal force, thereby separating them from the gas. Problems with gravity sedimentation separation technology: Separation efficiency is limited; gravity sedimentation separation efficiency is closely related to factors such as particle size and fluid velocity, resulting in poor separation effects; centrifugal separation principle has high requirements for feed materials and poor separation effect for certain materials.

[0027] like Figures 1 to 4 The embodiment of this application provides a solid-liquid-gas three-phase separator, which includes a cylinder 100, a filter assembly, a baffle plate 8, and a cyclone demister 6. The cylinder 100 has a separation chamber inside, with an air inlet 1, an air outlet 10, and a liquid outlet 5 connected thereto. The air inlet 1, air outlet 10, and liquid outlet 5 are respectively connected to the separation chamber. The filter assembly has filter holes and is installed inside the separation chamber. The filter assembly is used to filter and sieve the gas. The filter assembly can be installed inside the separation chamber by welding or screw connection. The filter holes on the filter assembly are used to sieve and filter powder in the gas. The air inlet 1 and air outlet 10 are located above the filter assembly, and the liquid outlet 5 is located below the filter assembly. The baffle plate 8 is installed in the separation chamber and located between the air inlet 1 and air outlet 10. The baffle plate 8 prevents untreated gas from being directly discharged through the air outlet 10. The air inlet 1 is located below the baffle plate 8. The cyclone demister 6 is installed on the filter assembly and the baffle 8. The outlet of the cyclone demister 6 is located between the baffle 8 and the air outlet 10, and the inlet of the cyclone demister 6 is located between the filter assembly and the drain outlet 5. In addition, the part of the cyclone demister 6 located on the upper side of the baffle 8 has an overflow port 7 to prevent liquid accumulation.
[0028] In this embodiment, the gas to be separated into solid, liquid, and gas phases is discharged through the air inlet 1. Since the baffle 8 is installed above the air inlet 1, the gas moves downwards and passes through the filter assembly. The filter assembly filters the gas to remove powder, and the liquid is discharged through the drain port 5. Then, the gas enters the cyclone demister 6 to separate the liquid. Finally, the gas is discharged through the air outlet 10, thus achieving the separation of solid, liquid, and gas phases in the gas. The separation efficiency is high and meets the actual needs.
[0029] In some embodiments, the solid-liquid-gas three-phase separator further includes a wire mesh demister 9, which is installed in the separation chamber. The wire mesh demister 9 can be welded to the separation chamber. The wire mesh demister 9 is located between the outlet of the cyclone demister 6 and the gas outlet 10. The wire mesh demister 9 is used to remove liquid from the gas, and then the treated gas is discharged through the gas outlet 10.
[0030] In some embodiments, the filter assembly may include a first filter plate 2, which is sleeved on the outside of the cyclone demister 6. The periphery of the first filter plate 2 is connected to the separation chamber. The filter holes on the first filter plate 2 have a diameter of 2 mm. The air inlet 1 is located on the side wall of the cylinder 100 between the partition 8 and the first filter plate 2.
[0031] In some embodiments, a first separation chamber is formed between the partition plate 8 and the first filter plate 2, and a first drain port 11a connected to the first separation chamber is provided on the cylinder 100. The first drain port 11a is used to discharge the filtered and screened powder in the gas.
[0032] In some embodiments, the filter assembly may further include a second filter plate 3, which is sleeved on the outside of the cyclone demister 6. The periphery of the second filter plate 3 is connected to the separation chamber. The filter holes on the second filter plate 3 have a diameter of 1 mm. The second filter plate 3 has an included angle with the first filter plate 2 and is located below the first filter plate 2.
[0033] In some embodiments, a second separation chamber is formed between the second filter plate 3 and the first filter plate 2, and a second drain port 11b connected to the second separation chamber is provided on the cylinder 100. The second drain port 11b is used to discharge the filtered and screened powder in the gas.
[0034] In some embodiments, the filter assembly may further include a third filter plate 4, which is sleeved on the outside of the cyclone demister 6. The periphery of the third filter plate 4 is connected to the separation chamber. The filter holes on the third filter plate 4 have a diameter of 0.5 mm. The third filter plate 4 has an included angle with the second filter plate 3 and is located below the second filter plate 3.
[0035] In some embodiments, a third separation chamber is formed between the third filter plate 4 and the second filter plate 3, and a third drain port 11c connected to the third separation chamber is provided on the cylinder 100. The third drain port 11c is used to discharge the filtered and screened powder in the gas.
[0036] Based on the above, the first filter plate 2, the second filter plate 3, and the third filter plate 4 are arranged at an angle of 15° to each other. The maximum distance between the first filter plate 2 and the second filter plate 3 is 500 mm, and the maximum distance between the second filter plate 3 and the third filter plate 4 is 500 mm. Since the filter holes on the first filter plate 2 are larger than those on the second filter plate 3, and the filter holes on the second filter plate 3 are larger than those on the third filter plate 4, the filter holes on the first filter plate 2, the second filter plate 3, and the third filter plate 4 perform step-by-step filtration and sieving of the powder in the gas. The filtered and sieved gas then enters the cyclone demister 6 for gas-liquid separation.
[0037] Based on the above, the thickness of the first filter plate 2, the second filter plate 3, and the third filter plate 4 is 3mm. The outer and inner edges of the first filter plate 2, the second filter plate 3, and the third filter plate 4 are reserved with a 20mm diameter without openings. The inner edge of the cylinder 100 and the outer edge of the cyclone demister 6 are welded to the inner and outer edges, respectively. When the aperture is 2mm, the center distance between the two apertures is 3mm; when the aperture is 1mm, the center distance between the two apertures is 1.5mm; and when the aperture is 0.5mm, the center distance between the two apertures is 1mm.
[0038] In some embodiments, the solid-liquid-gas three-phase separator further includes a viewing mirror 12, which is installed on the cylinder 100 for observing the separation chamber, so as to observe the separation of gas and solid inside the separation chamber at any time.
