It utilizes the different volatilities of the components in the mixture, that is, the different vapor pressures of the components at the same temperature. The light components (low boiling substances) in the liquid phase are transferred to the gas phase, and the heavy components (high boiling substances) in the gas phase are transferred to the liquid phase, thereby achieving the purpose of separation.

[0033] The bearing tower plate mechanism 3 includes a tower plate seat 301, and multiple tower plate seats 301 are fixedly installed on one side of the inner cavity of the first tower body 1. Multiple tower plate seats 301 are fixedly installed on the inner cavity of the second tower body 2 and the side corresponding to the tower plate seat 301 of the first tower body 1 through a connecting block 302.

[0034] The specific implementation method is as follows: after the material enters the second tower body 2 through the liquid inlet pipe on one side, the material can be heated and volatilized by the heating effect of the second tower body 2 and the first tower body 1, and under the action of the gas phase of the material continuously introduced, the material mixture can enter the packing slot seat 403 through the limiting groove 303 on the bottom side of the bottom tower plate body 304 to turbulently mix and transfer mass with the packing medium. After the gas-liquid flow is separated under the mass transfer effect, the airflow enters the top packing frame 401 and overflows from both sides of the packing frame 401. At the same time, the separated liquid can flow downward through the groove cavity between the tower plate body 304 and the tower plate seat 301 into the bottom of the inner cavity of the tower seat 6 and be discharged through the liquid pumping equipment.

[0035] See also Figure 3-4 The packing processing mechanism 4 includes a packing frame 401, a packing placement groove 402 is opened at the bottom of the inner cavity of the packing frame 401, and the packing placement groove 402 is filled with a packing medium. A packing groove seat 403 is fixedly connected to the bottom of the packing frame 401, and the packing groove seat 403 is a mesh groove seat, which is used to enhance the mass transfer of gas and liquid entering through the limiting groove 303 through the packing medium to perform gas-liquid separation. A plurality of liquid lifting plates 404 are fixedly connected to the top of the inner cavity of the packing frame 401, and the liquid lifting plates 404 extend in a wave shape.

[0036] The specific implementation method is as follows: the filling slot seat 403 can ensure that the pressurized gas enters the filling slot seat 403 through the mesh holes of the mesh slots, and at the same time, the filling medium can ensure the dispersion of the gas-liquid medium through its own microporous structure. At the same time, multiple wavy extended liquid lifting plates 404 can fully disperse and transfer the incoming gas-liquid raw materials in a stacked setting, further improving the distillation separation effect of the principle. At the same time, the wavy extended liquid lifting plates 404 can increase the heat exchange efficiency with the raw materials and ensure the processing effect of the raw materials.

[0037] See also Figure 3-7The transmission mechanism 5 includes an abutment rod 501, and a plurality of abutment blocks 502 are connected to the outside of the abutment rod 501 along the axis, and one side of the abutment block 502 is in contact with one side of the liquid extraction plate 404. Both ends of the abutment rod 501 are provided with bearing seats 509 through bearing sleeves, and the bearing seats 509 are fixedly connected to the top of the tower plate body 304. A driven gear 503 is fixedly installed at the end of the abutment rod 501, and one side of the plurality of driven gears 503 is meshed with a limited position rack 504. A triangular plate 505 is fixedly connected to one side of the limited position rack 504, and the top of the triangular plate 505 is in contact with the liquid extraction plate 404. There is an abutment roller 507, and a transmission rod 506 is fixedly connected between the multiple abutment rollers 507. Both ends of the transmission rod 506 are fixedly connected to one side of the inner cavity of the first tower body 1 through a fixed block 508. The top inclined surface of the triangular plate 505 is in contact with one side of the abutment roller 507. A slider is fixedly connected to the bottom of the triangular plate 505.

A spring is fixedly connected between the slider and one side of the inner cavity of the slide groove 510. The stroke of the triangular plate 505 is smaller than the diameter difference between the limiting rack 504 and the inner cavity of the first tower body 1.

[0038] The specific implementation method is as follows: when the first tower body 1 is pulled by the bottom lifting cylinder 9, the first tower body 1 can drive the transmission rod 506 to move downward through the inner fixed block 508. The downward movement of the transmission rod 506 can drive the abutting roller 507 on one side to squeeze and fit with the top of the triangular plate 505. After the triangular plate 505 fits, it can pull the limiting rack 504 on one side to slide in the slide groove 510 through the bottom slider. The sliding of the limiting rack 504 can drive the driven gear 503 meshing at the top to rotate. The rotation of the driven gear 503 can drive the abutting rod 501 to rotate. The rotation of the abutting rod 501 can drive the outer abutting block 502 to rotate. The rotation of the abutting block 502 can drive the liquid lifting plate 404 abutted on one side to deviate relatively. The disturbance deviation of the liquid lifting plate 404 can further improve the distillation treatment of the rising material. The deviation of the liquid lifting plate 404 can squeeze the filling medium in the bottom filling placement groove 402. The filling medium is disturbed by the liquid lifting plate 404. Under the action of, they can touch each other and agglomerate the adhered solutions into the drainage groove of the tower plate main body 304 and penetrate downward, so that under the lifting action of the first tower body 1, the disturbance cleaning of the filler processing mechanism 4 and the processing empowerment of the extraction liquid can be simultaneously realized, and the distillation processing effect of the material can be further improved. Through the designed slider, the sliding of the triangular plate 505 in the slide groove 510 through the slider is more stable. At the same time, the top of the triangular plate 505 is an inclined surface, which can ensure full contact with the extruded abutment roller 507, reduce the extrusion friction, and improve the extrusion stability. At the same time, the slider can squeeze the spring in the inner cavity of the slide groove 510 when moving, and then pull the limit rack 504 to reset when the first tower body 1 is reset, and the reset of the limit rack 504 can synchronously drive the abutment block 502 to reverse, further disturbing and mixing the extraction plate 404, and at the same time, the abutment blocks 502 arranged around can ensure the randomness of the disturbance and improve the processing effect.

[0039] See also Figure 1-2, two positioning columns are fixedly connected to the bottom of the inner cavity of the transmission groove 10, and the two positioning columns are slidably connected to the positioning holes opened at the corresponding positions on the top of the connecting block 302. The first tower body 1 is fixedly connected with a corrugated cover 8 at both ends, and the other end of the corrugated cover 8 is fixedly connected to the tower top 7 at the corresponding position and one side of the second tower body 2. The corrugated cover 8 is a high-temperature resistant plastic elastic cover. The first tower body 1 and the second tower body 2 are fixedly connected to a bearing seat 12 on one side of the outer wall, and the top of the bearing seat 12 is provided with assembly holes around it. The outer wall of the second tower body 2 is fixedly connected to the outer wall by mounting parts around it. It is connected to a lifting cylinder 9, one end of the piston rod of the lifting cylinder 9 is inserted between the assembly holes on both sides and extends to the outer wall of the first tower body 1, the outer wall of the first tower body 1 is fixedly connected to one side of the piston rod of the lifting cylinder 9 at the corresponding position through a connecting piece 13, the cross-sectional shape of the connecting block 302 is arc-shaped, the curvature of the connecting block 302 matches the arc of the transmission groove 10, the top of the tower top 7 is connected to a gas phase feed pipe through a gas phase pipe and a condensation reflux mechanism, the bottom of the tower base 6 is connected to a liquid phase feed pipe, and the second tower body 2 is connected to a feed pipe 11 at a corresponding position on the side close to the tower top 7.

[0040] The specific implementation method is as follows: through the designed positioning column, the movement stability of the first tower body 1 in the positioning hole of the connecting block 302 on one side can be ensured through the positioning column. At the same time, a sealing gasket body can be connected between the two sides of the positioning column and the transmission groove 10 on one side of the first tower body 1. The sealing gasket body ensures the pressure stabilizing effect of the inner cavity of the first tower body 1 under the cooperation of the corrugated cover 8, and can effectively avoid the heat dissipation in the first tower body 1 and the second tower body 2. Multiple groups of lifting airbags can improve the stability of the movement of the first tower body 1.

[0041] Working principle: After the material enters the second tower body 2 through the liquid inlet pipe on one side, the material is heated and volatilized by the heating effect of the second tower body 2 and the first tower body 1, and the material mixture enters the packing slot seat 403 through the limiting groove 303 on the bottom side of the bottom tower plate body 304 to turbulently mix and transfer mass with the packing medium. After the gas-liquid flow is separated under the mass transfer effect, the airflow enters the top packing frame 401 and overflows from both sides of the packing frame 401. The separated liquid flows downward through the groove cavity between the tower plate body 304 and the tower plate seat 301 into the bottom of the inner cavity of the tower seat 6 and is discharged through the liquid pumping equipment. The packing slot seat 403 ensures the pressure gas through the mesh mesh. The body enters the packing slot seat 403, and the packing medium ensures the dispersion of the gas-liquid medium through its own microporous structure. The liquid flowing downward realizes the mass transfer separation and distillation treatment of the gas-liquid state raw materials under the cooperation of the multiple staggered tower plate seats 301 and the tower plate body 304. The piston rod is pulled by the lifting cylinder 9 to drive the top first tower body 1 to move downward. The movement of the first tower body 1 drives the tower plate connected to the inner cavity on one side and the tower plate body 304 to adjust the gap between the tower plate body 304 corresponding to the second tower body 2 side, which is conducive to controlling the height of the falling liquid layer by controlling the height of the liquid layer between the multiple staggered tower plate bodies 304.

[0042] When the first tower body 1 is pulled by the bottom lifting cylinder 9, the first tower body 1 drives the transmission rod 506 to move downward through the inner fixed block 508. The transmission rod 506 moves downward to drive the abutting roller 507 on one side to squeeze and fit with the top of the triangular plate 505. After the triangular plate 505 fits, it pulls the limiting rack 504 on one side to slide in the slide groove 510 through the bottom slider. The sliding of the limiting rack 504 drives the driven gear 503 meshing at the top to rotate. The rotation of the driven gear 503 drives the abutting rod 501 to rotate. The rotation of the abutting rod 501 drives the outer abutting block 502 to rotate. The rotation of the abutting block 502 drives the liquid lifting plate 404 abutting on one side to deviate relatively. The disturbance and deviation of the liquid lifting plate 404 further improves the distillation treatment of the rising material. The displacement of the liquid lifting plate 404 squeezes the filling medium in the bottom filling placement groove 402. The filling medium touches each other under the disturbance of the liquid lifting plate 404, and the adhered solutions are agglomerated with each other and enter the drainage groove of the tower plate body 304 and penetrate downward. The sliding of the triangular plate 505 in the slide groove 510 is more stable through the slider. The slider squeezes the spring in the inner cavity of the slide groove 510 when moving, and then pulls the limit rack 504 to reset when the first tower body 1 is reset. The reset of the limit rack 504 synchronously drives the abutment block 502 to reverse, and further disturbs the liquid lifting plate 404 for mixing.
