Description

Technical Field

[0001] The invention relates to the technical field of plate towers, in particular to a plate tower for high-speed gas-liquid mass transfer. Background Art

[0002] The plate tower is a type of graded contact mass transfer equipment used for gas-liquid or liquid-liquid systems. It consists of a cylindrical tower body and a number of plates installed horizontally in the tower at a certain interval. It is widely used in distillation and absorption. Some types (such as sieve plate towers) are also used for extraction. It can also be used as a reactor for gas-liquid phase reaction processes. During operation (taking the gas-liquid system as an example), the liquid flows through each layer of the tower plate from top to bottom under the action of gravity and is discharged at the bottom of the tower; the gas passes through each layer of the tower plate from bottom to top under the pressure difference and is discharged at the top of the tower. A liquid layer of a certain depth is maintained on each tower plate, and the gas is dispersed into the liquid layer through the tower plate for interphase contact mass transfer.

[0003] At present, the thickness of the liquid layer on the tower plate in the existing plate tower is determined by the height of the outlet weir, and the gas enters and passes through the liquid layer on the plate from bottom to top through the openings on the tower plate to achieve heat or mass transfer. In this traditional plate tower, especially when the gas phase load is low, the contact area between the gas and liquid phases is small, and the contact time between the gas and liquid phases is relatively short, resulting in relatively low heat and mass transfer efficiency and speed between the gas and liquid phases, which cannot meet people's needs for distillation separation between different materials.

[0010] Furthermore, the through hole is arranged obliquely, and the inner diameter of the through hole gradually decreases in a direction away from the end of the adjusting tube.

[0011] Furthermore, a fixed ring plate is fixedly connected to the top outer wall of the tower plate, and the number of the fixed ring plates is three groups.

[0014] Furthermore, a buffer seat is fixedly connected to the bottom end of the adjusting cylinder, an overflow hole is arranged in the middle of the buffer seat, and the cross section of the buffer seat is W-shaped.

[0015] Beneficial effects of the present invention: The plate tower for high-speed gas-liquid mass transfer provided by the present invention can realize gas-liquid graded contact heat and mass transfer between materials, meeting people's needs for separation of different materials. Specifically, through the set mass transfer component, when people need to distill and separate the materials, they can first inject them into the tower body through the feed pipe, and at the same time introduce the high-temperature gas into the tower body through the air inlet pipe. Since the gas phase inside the tower barrel is relatively small when the liquid phase is just injected, most of the liquid phase falling on the top of the tower plate flows out from the sieve holes opened on the top of the tower plate. At this time, the liquid layer on the tower plate is not high and cannot overflow the upper edge of the regulating cylinder, so that there is no liquid holding volume in the regulating cylinder. At this time, the liquid phase falling from the sieve holes will contact with the rising gas phase for gas-liquid heat and mass transfer. As the gas phase inside the tower body continues to increase, the flow rate of the liquid phase falling from the sieve holes will slow down. At this time, the liquid phase will gradually accumulate on the top of the tower plate. When the liquid phase accumulates to the same height as the regulating cylinder, the liquid phase It will slide down along the inner wall of the regulating cylinder, and at the same time, the gradually increasing gas phase will bulge in from the inside of the through hole and can lift up the floating plate, so that the liquid phase and the gas phase can collide and contact each other up and down, and then fully mix to carry out gas-liquid mass transfer and heat transfer, and the through holes are inclinedly distributed on the circumferential outer wall of the regulating cylinder, so that the upward impact of the gas phase can be greater, and with the continuous influx of the gas phase, it will contact with the first arc plate of the dispersion plate, so that an oblique upward thrust can be applied to the surface of the first arc plate, and when the first arc plate is subjected to the oblique upward thrust, the entire dispersion plate and the floating plate will make a circular motion and rotate, and in the process of the self-rotation of the dispersion plate, not only can the contact between the gas phase and the liquid phase be accelerated, thereby making the gas-liquid mass transfer more efficient, and realizing high-speed mass transfer of the entire plate tower, but also through the cooperation of the annular plate and the tooth groove, the bubbles generated in the contact process between the gas phase and the liquid phase can be punctured, thereby further improving the rapid mass transfer between the gas and the liquid; After the gas phase contacts the first arc plate and causes the dispersion sheet to rotate, the gas phase will rise along the outer wall of the second arc plate, thereby providing a good guide for the gas phase and enabling the gas phase to fully contact and transfer mass with the liquid phase sliding down the inner wall of the regulating cylinder.

[0016] The plate tower for high-speed gas-liquid mass transfer provided by the present invention can play a good role as a flow guide component for the liquid phase overflowing from the tower plate, so as to avoid the collision between the liquid phase and the surface of the tower plate below to cause excessive bubbles to occur. Specifically, through the provided flow guide component, as the liquid phase is continuously injected, the liquid level of the liquid phase on the tower plate will gradually rise. When the liquid phase on the tower plate rises to a certain height, it will overflow from the top of the overflow plate. At this time, the liquid phase will slide from the other side of the overflow plate to the inclined plate part. When the liquid phase slides along the surface of the inclined plate part When falling, it will flow into the guide groove through the first circular groove and the inclined groove. The liquid phase flowing into the guide groove will flow to the top outer wall of the other tower plate through the rectangular groove on the other side when sliding down along its inner wall. At the same time, the liquid phase sliding to the bottom end of the inclined plate will also flow to the top outer wall of the other tower plate through the arc groove, and the dispersion plate arranged inside the arc groove also has a good defoaming effect, so that a large number of bubbles will not appear in the process of the liquid phase flowing from one group of mass transfer components to another mass transfer component, which is beneficial to the subsequent high-speed mass transfer of gas and liquid inside the tower body.

The vertical plate portion is fixedly connected to the outer wall of one side of the tower plate 5001, and the bottom end of the inclined plate portion contacts the top outer wall of another tower plate 5001. When people need to perform distillation separation on the material, they can first inject it into the tower body 1 through the feed pipe 6, and at the same time, introduce the high-temperature gas into the tower body 1 through the air inlet pipe 4. Since the gas phase inside the tower is relatively small when the liquid phase is just injected, most of the liquid phase falling on the top of the tower plate 5001 flows out from the sieve hole 5003 opened on the top of the tower plate 5001 for gas-liquid mass transfer; A flow guide assembly 8 is provided on one side of the inclined plate portion; The top of the tower plate 5001 is provided with float valve assemblies 9 which are distributed at equal distances.

[0034] Preferably, the guide assembly 8 includes a guide groove 8001 provided on the outer wall of one side of the inclined plate portion of the overflow plate 5002, the cross section of the guide groove 8001 is in a water drop shape, the inner diameter of the guide groove 8001 gradually increases from top to bottom, and the outer wall of one side of the inclined plate portion is provided with an equidistantly distributed inclined groove 8005 and a first circular groove 8006, the first circular groove 8006 and the inclined groove 8005 are both connected to the guide groove 8001, and the inclined plate portion is away from the inclined groove 8005 and the first circular groove 8006. A rectangular groove 8002 is provided on one side of a circular groove 8006, and arc grooves 8003 are provided on the outer wall of the bottom of the inclined plate at equal distances. One group of arc grooves 8003 is located in the middle of the two groups of guide grooves 8001. The inner wall of the arc groove 8003 is fixedly connected with a dispersion plate 8004. The dispersion plates 8004 are distributed in an arc shape at equal distances on the inner wall of the arc groove 8003. As the liquid phase is continuously injected, the liquid phase on the tower plate 5001 is The liquid level will also gradually rise. When the liquid phase on the tower plate 5001 rises to a certain height, it will overflow from the top of the overflow plate 5002. At this time, the liquid phase will slide from the other side of the overflow plate 5002 to the inclined plate portion. When the liquid phase slides along the surface of the inclined plate portion, it will flow into the guide groove 8001 through the first circular groove 8006 and the inclined groove 8005. The liquid phase flowing into the guide groove 8001 will flow along its inner wall through the rectangular groove 8002 on the other side to the top outer wall of the other tower plate 5001. At the same time, the liquid phase that slides to the bottom of the inclined plate portion will also flow to the top outer wall of the other tower plate 5001 through the arc groove 8003, and the dispersion plate 8004 arranged inside the arc groove 8003 also has a good defoaming effect, so that a large number of bubbles will not appear in the process of the liquid phase flowing from one group of mass transfer components 5 to another mass transfer component 5, which is conducive to the subsequent high-speed mass transfer of gas and liquid in the tower body 1.

[0035] Preferably, the float valve assembly 9 includes a mounting hole provided on the outer wall of the top of the tower plate 5001, an adjusting cylinder 9001 is fixedly connected inside the mounting hole, the inner diameter of the adjusting cylinder 9001 gradually decreases from top to bottom, the cross section of the adjusting cylinder 9001 is an isosceles trapezoid, a floating plate 9010 is provided inside the adjusting cylinder 9001, a fixing column 9005 is provided inside the adjusting cylinder 9001, the floating plate 9010 is sleeved on the circumferential outer wall of the fixing column 9005, the circumferential outer wall of the adjusting cylinder 9001 is provided with through holes 9003 which are equidistantly distributed in a circular shape, and the through holes 9003 are arranged obliquely. The inner diameter of the through hole 9003 gradually decreases in the direction away from the end of the regulating cylinder 9001. As the gas phase inside the tower body 1 continues to increase, the flow rate of the liquid phase falling from the sieve hole 5003 will slow down. At this time, the liquid phase will gradually accumulate on the top of the tower plate 5001. When the liquid phase accumulates to the same height as the regulating cylinder 9001, the liquid phase will slide along the inner wall of the regulating cylinder 9001. At the same time, the gradually increasing gas phase will blow in from the inside of the through hole 9003 and then lift up the floating plate 9010, so that the liquid phase and the gas phase can collide and contact each other up and down, and then fully mix to carry out gas-liquid mass transfer and heat transfer.

[0036] Preferably, the top outer wall of the tower plate 5001 is fixedly connected with a fixed ring plate 5004, the number of the fixed ring plates 5004 is three groups, the top outer wall of the fixed ring plate 5004 is fixedly connected with a reinforcing plate 11, the end of the reinforcing plate 11 away from the fixed ring plate 5004 is fixedly connected with a circular ring plate 12, and the circular ring plate 12 is fixedly connected to the fixed column 9005, which can extend the time for the liquid phase to flow from the surface of the tower plate 5001 to the surface of another tower plate 5001, thereby increasing the contact time between the liquid phase and the gas phase, which is beneficial to sufficient mass transfer between the liquid phase and the gas phase.

[0037] Preferably, the top outer wall of the floating plate 9010 is fixedly connected with a dispersion piece 9007, and the dispersion piece 9007 is distributed in an equidistant circle on the top outer wall of the floating plate 9010. The dispersion piece 9007 includes a first arc plate 9011 and a second arc plate 9012. One end of the first arc plate 9011 is fixedly connected to the top outer wall of the floating plate 9010. An annular piece 9008 distributed in an equidistant manner is fixedly connected to one side outer wall of the dispersion piece 9007. An equidistant tooth groove 9009 is provided on one side outer wall of the annular piece 9008. The cross section of the tooth groove 9009 is triangular. The bottom end of the adjusting cylinder 9001 is fixedly connected to There is a buffer seat 9004, and an overflow hole 9006 is arranged in the middle of the buffer seat 9004. The cross section of the buffer seat 9004 is W-shaped. Through the cooperation of the circular ring 9008 and the tooth groove 9009, the bubbles generated during the contact between the gas phase and the liquid phase can be punctured, thereby further improving the rapid mass transfer between the gas and the liquid. After the gas phase contacts with the first arc plate 9011 to rotate the dispersion plate 9007, the gas phase will rise along the outer wall of the second arc plate 9012, thereby being able to play a good guiding role for the gas phase, so that the gas phase can fully contact and transfer with the liquid phase sliding along the inner wall of the regulating cylinder 9001.

[0038] In summary, with the aid of the above technical scheme of the present invention, when people need to distill and separate the material, they can first inject it into the tower body 1 through the feed pipe 6, and at the same time introduce the high-temperature gas into the tower body 1 through the air inlet pipe 4. Since the gas phase inside the tower tube is relatively small when the liquid phase is just injected, most of the liquid phase falling on the top of the tower plate 5001 flows out from the sieve hole 5003 opened on the top of the tower plate 5001. At this time, the liquid layer on the tower plate 5001 is not high and cannot overflow the upper edge of the regulating tube 9001, so that there is no liquid holding capacity in the regulating tube 9001. At this time, the liquid phase falling from the sieve hole 5003 will contact with the rising gas phase to carry out gas-liquid heat and mass transfer. As the gas phase inside the tower body 1 continues to increase, the liquid phase falling from the sieve hole 5003 will The falling liquid phase flow rate slows down, and the liquid phase will gradually accumulate on the top of the tower plate 5001. When the liquid phase accumulates to the same height as the regulating cylinder 9001, the liquid phase will slide down along the inner wall of the regulating cylinder 9001, and at the same time, the gradually increasing gas phase will bulge in from the inside of the through hole 9003 and can lift up the floating plate 9010, so that the liquid phase and the gas phase can collide and contact each other up and down, and then fully mix to carry out gas-liquid mass transfer and heat transfer. The through holes 9003 are inclinedly distributed on the circumferential outer wall of the regulating cylinder 9001, so that the upward impact of the gas phase can be greater. As the gas phase continues to flow in, it will contact the first curved plate 9011 of the dispersion sheet 9007, so that an oblique upward thrust can be applied to the surface of the first curved plate 9011. When the first curved plate 90 When the dispersing plate 9007 is subjected to an oblique upward thrust, the dispersing plate 9007 and the floating plate 9010 will rotate in a circular motion. In the process of the dispersing plate 9007 rotating, not only can the contact between the gas phase and the liquid phase be accelerated, thereby making the gas-liquid mass transfer more efficient and realizing the high-speed mass transfer of the entire plate tower, but also the bubbles generated in the contact process between the gas phase and the liquid phase can be punctured through the cooperation of the annular plate 9008 and the tooth groove 9009, thereby further improving the rapid mass transfer between the gas and the liquid. After the gas phase contacts the first arc plate 9011 to rotate the dispersing plate 9007, the gas phase will rise along the outer wall of the second arc plate 9012, thereby having a good guiding effect on the gas phase, so that the gas phase can be with the liquid phase along the regulating cylinder 90 01, the liquid phase sliding down the inner wall is fully contacted for mass transfer. With the continuous injection of the liquid phase, the liquid level on the tower plate 5001 will gradually rise. When the liquid phase on the tower plate 5001 rises to a certain height, it will overflow from the top of the overflow plate 5002. At this time, the liquid phase will slide from the other side of the overflow plate 5002 to the inclined plate portion. When the liquid phase slides along the surface of the inclined plate portion, it will flow into the guide groove 8001 through the first circular groove 8006 and the inclined groove 8005. The liquid phase flowing into the guide groove 8001 will flow to the top outer wall of the other tower plate 5001 through the rectangular groove 8002 on the other side when sliding down along its inner wall. At the same time, the liquid phase sliding to the bottom of the inclined plate portion will also flow to the top outer wall of the other tower plate 5001 through the arc groove 8003.The dispersion plate 8004 disposed inside the arc groove 8003 also has a good defoaming effect, so that a large number of bubbles will not appear in the process of the liquid phase flowing from one mass transfer component 5 to another mass transfer component 5, which is conducive to the subsequent high-speed mass transfer of gas and liquid inside the tower body 1.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
