Description

[0001] The present invention relates to the technical field of carbon dioxide processing, in particular to carbon dioxide gas capturing equipment for ships. Background Art

[0002] Shipboard carbon capture technology is a strategic technology that is expected to achieve large-scale low-carbon utilization of fossil energy. It is an important means to reduce carbon dioxide (CO2), ensure energy security, build ecological civilization and achieve sustainable development in the future. Since ship exhaust has the characteristics of large flow and low CO2 concentration, chemical absorption method can be selected for carbon capture technology.

[0003] Among them, fillers play a vital role in existing carbon dioxide capture technology. By rationally designing the type and structure of fillers, the capture efficiency and operational flexibility can be significantly improved. However, the fillers in existing carbon dioxide gas capture equipment are easily blocked by particulate matter after a long period of use. Therefore, regular replacement of fillers with reduced performance can improve operational efficiency and reduce energy consumption. However, in the existing technology, the removal and replacement of fillers usually requires downtime, which not only causes the production line to stop, affecting production efficiency and economic losses, but also the removal of fillers may be damaged or lost during the removal and replacement process, resulting in incomplete subsequent installation or affecting the operating effect.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 10 The present invention provides a technical solution: a carbon dioxide gas capture device for ships, comprising a frame 1, a tower body 2, a spray plate 6 and a main filler assembly 8 arranged in the tower body 2, an air inlet 3, an air outlet 4, a liquid inlet pipe 5 and a liquid discharge port 7 are sequentially arranged on the tower body 2, the spray plate 6 is fed with absorbent through the liquid inlet pipe 5, the air outlet 4 is arranged at the top of the tower body 2, and the air inlet 3 and the liquid discharge port 7 are sequentially distributed on the left and right sides of the bottom of the tower body 2. An opening for accommodating a main packing assembly 8 is provided at the front end of the tower body 2, one end of the main packing assembly 8 is detachably fixedly connected to a packing installation plate 9, and the other end of the main packing assembly 8 passes through the opening and is plugged into the tower body 2; a group of additional shells 14 are fixedly provided on both horizontal sides of each group of openings, and an auxiliary packing assembly 13 is detachably installed in each group of additional shells 14, an upper flow hole 201 connected to the top of the additional shell 14 and a lower flow hole 202 connected to the bottom are provided on the side wall of the tower body 2, and a branch liquid guide tube 15 is provided at the bottom of each group of additional shells 14, and multiple branch liquid guide tubes 15 are commonly connected to a main liquid guide tube 16, and the lower end of the main liquid guide tube 16 is connected to the drain port 7, and the packing installation plate 9 is detachably installed in the opening through a plug-in assembly; Two sets of switching plates 11 are symmetrically arranged at the upper and lower ends of each set of filling components. The switching plates 11 are driven by the pushing component and rotate 90° forward and reverse, so as to switch between the main filling component 8 and the auxiliary filling component 13. A guide plate 12 is arranged at each set of downstream holes 202. The guide plate 12 deflects up and down under the drive of the linkage component, so as to alternately open the downstream holes 202 and the branch drainage tube 15. The linkage component is powered by the pushing component, and the pushing component is powered by the plug-in component.

[0032] Furthermore, the present invention forms two groups of packing channels by arranging the main packing components 8 and the auxiliary packing components 13 for alternate use, so that a single packing component can be maintained without stopping the overall operation, thereby reducing downtime. Moreover, during the maintenance of one group of packing components, the sealing operating space of the other group of packing components is not affected, thereby ensuring the relative stability and continuity of the system.

[0033] Specifically, the flue gas after dust removal enters the tower body 2, and the flue gas flows from bottom to top, while the absorbent is sprayed down from the top of the tower through the spray plate 6, and the two are in reverse contact. CO2 reacts with the absorbent in the absorption tower and is absorbed, and the flue gas after partial carbon removal is discharged from the exhaust port 4 at the top of the tower. After absorbing CO2, the absorbent changes from lean liquid to rich liquid and flows to the bottom of the tower. It is pumped out of the tower body 2 from the liquid discharge port 7 by a pump, and then flows through the heat exchanger and is sent to the desorption tower. In the desorption tower, the rich liquid is heated to a certain temperature to release CO2, and the absorbent becomes lean liquid. The desorbed CO2 is discharged from the top of the tower, compressed after drying and dehydration, and can be used for subsequent utilization and storage, and the regenerated absorbent lean liquid is cooled by the heat exchanger and sent back to the absorption tower through the liquid inlet pipe 5 for CO2 cyclic absorption.

[0034] like Figure 4-Figure 10 As shown, the plug-in assembly includes two groups of symmetrical push plates 30, which are slidably mounted on the filler mounting plate 9. A No. 2 spring 31 is fixedly provided on the side where the two groups of push plates 30 are close to each other, and a vertical plug plate 29 is fixedly connected to the side of the push plate 30 away from the No. 2 spring 31. A cover 10 is rotatably mounted on the outer wall of the filler mounting plate 9, and the cover 10 surrounds and shields the push plate 30.

[0035] Furthermore, by setting up a push plate 30, a vertical plug plate 29 and a second spring 31 for use together, on the one hand, the filling installation plate 9 can be detachably fixed at the opening to achieve rapid limiting fixation of the main filling assembly 8; on the other hand, as the power output of the pushing component, the mechanical linkage is strong, so that the switching plate 11 can adaptively flip up and down according to the movement state of the filling installation plate 9, ensuring that the removal and replacement process of the main filling assembly 8 is carried out in a state isolated from the space inside the tower.

[0036] like Figure 8-Figure 10As shown, the vertical plug plate 29 penetrates the packing mounting plate 9 and extends into the tower body 2 to be connected to the pushing component, which includes a rotating shaft 17, a cylindrical cam 18, a toggle pin 23, a connecting bar 24, a horizontal plug plate 25, a No. 1 spring 26 and a moving seat 27. The connecting bar 24 is limitedly slidably installed in the tower body 2, one end of the connecting bar 24 is fixedly connected to the moving seat 27, and the other end of the connecting bar 24 is fixedly connected to two groups of horizontal plug plates 25. The side wall of the switching plate 11 is provided with a bite groove 1101 for accommodating the horizontal plug plate 25. A group of No. 1 springs 26 are symmetrically arranged on both sides of the moving seat 27, and the No. 1 spring 26 is fixedly connected to the connecting bar 24, and the elastic force of the No. 1 spring 26 is much smaller than the elastic force of the No. 2 spring 31. The upper end surface of the moving seat 27 is provided with a wedge-shaped groove 28 for accommodating the vertical plug plate 29. Both horizontal ends of the connecting bar 24 are fixedly connected with a toggle pin 23, which is inserted into the wheel groove of the cylindrical cam 18. The cylindrical cam 18 is installed in the tower body 2 for limited rotation, and the wheel groove of the cylindrical cam 18 is composed of a quarter-turn spiral groove in the middle and straight grooves at both ends.

[0037] Furthermore, by setting a rotating shaft 17, a cylindrical cam 18, a toggle pin 23, a connecting strip 24, a transverse plug plate 25, a No. 1 spring 26 and a moving seat 27 for use in combination, the horizontal driving force of the packing mounting plate 9 can be converted into a synchronous 90° flipping movement of multiple groups of switching plates 11, and the wheel groove of the cylindrical cam 18 is composed of a quarter-turn spiral groove in the middle and straight grooves at both ends. This can ensure that during the extension or extension of the main packing component 8, the two adjacent groups of switching plates 11 are in a state of mutual closure, so that liquid and gas can only flow into the next layer or the previous layer through the additional shell 14. Only when the packing mounting plate 9 is fixedly inserted in the opening, the switching plate 11 will flip upward to close the upper flow hole 201 and the lower flow hole 202, thereby ensuring the sealing performance during the packing maintenance process.

[0038] like Figure 3 , Figure 6-Figure 8 As shown, the cylindrical cam 18 is coaxially fixedly connected with the rotating shaft 17, the outer part of the rotating shaft 17 is fixedly sleeved with the switching plate 11, and the end of the rotating shaft 17 away from the cylindrical cam 18 is connected to the linkage component. The linkage component includes a driving wheel 19, a driven rack 20, a driven wheel 21 and a deflection shaft 22. The driving wheel 19 is coaxially fixedly connected with the rotating shaft 17, the driven gear is limitedly slidably installed in the tower body 2, and the driven gear is meshed and connected with the driving wheel 19 and the driven gear at the same time. The driven wheel 21 is coaxially fixedly connected with the deflection shaft 22, the deflection shaft 22 is limitedly rotatably installed in the tower body 2, and the outer part of the deflection shaft 22 is fixedly sleeved with the guide plate 12.

[0039] Furthermore, by setting the driving wheel 19, the driven rack 20, the driven wheel 21 and the deflection shaft 22 for use in conjunction, the guide plate 12 can be deflected synchronously according to the movement state of the switching plate 11. When the switching plate 11 blocks the upper flow hole 201 and the lower flow hole 202, the guide plate 12 can immediately flip downward to open the branch flow guide tube 15, so that the residual waste liquid in the installation shell 14 can smoothly flow into the drain port 7 for later reuse.

[0040] like Figure 4 as well as Figure 5 As shown, the upflow hole 201 and the downflow hole 202 are both inclined holes, and the inclination angle of the upflow hole 201 is opposite to the inclination angle of the downflow hole 202. The bottom of the additional shell 14 is arranged in an inclined shape near one end of the branch flow guide tube 15, and the main filler assembly 8 is arranged in no less than two groups.

[0041] Furthermore, by setting the upflow hole 201 and the downflow hole 202 as inclined holes, the absorbent can flow from the upper end of the switching plate 11 into the upflow hole 201, then flow from the upflow hole 201 into the additional shell 14, and finally smoothly pass through the downflow hole 202 and flow from the additional shell 14 into the tower body 2 again.

[0042] When the present invention is used: the flue gas after dust removal enters the tower body 2, the flue gas flows from bottom to top, and the absorbent is sprayed down from the top of the tower through the spray plate 6, and the two are reversely contacted through multiple groups of main filler components 8, CO2 reacts with the absorbent in the absorption tower and is absorbed, and the flue gas after part of the carbon is removed is discharged from the exhaust port 4 at the top of the tower; after absorbing CO2, the absorbent changes from lean liquid to rich liquid and flows to the bottom of the tower, and is pumped out of the tower body 2 from the discharge port 7 by a pump, and then flows through the heat exchanger and is sent to the desorption tower; When routinely replacing the main filling assembly 8, the cover 10 is opened, and the two sets of push plates 30 are first pressed inward and kept pressed. At this time, the vertical plug plate 29 is pulled out from the wedge-shaped groove 28, thereby releasing the squeezing force on the moving seat 27, so that the connecting bar 24 drives the horizontal plug plate 25 and the moving seat 27 to move toward the switching plate 11 under the elastic force of the No. 1 spring 26. In this process, the toggle pin 23 on the connecting bar 24 first acts on the spiral groove of the cylindrical cam 18 and then drives into the linear groove, so that the switching plate 11 quickly flips downward 90° and then remains stationary. The horizontal plug plate 25 is smoothly inserted into the bite groove 1101, so that the switching plate 11 is stabilized in a horizontal position, so that gas and liquid are no longer passed into the main filling component 8. At this time, the upper flow hole 201 and the lower flow hole 202 are both opened, so that the flue gas and the absorbent enter the installation shell 14 and react with the auxiliary filling component 13. At this time, the main filling component 8 is pulled out of the tower body 2 under the force of the filling installation plate 9 for cleaning and maintenance. The main filling component 8 is isolated from the tower body 2 during the disassembly and assembly process, thereby ensuring the relative stability and continuity of the system.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
