Description

Technical Field

[0001] The present invention relates to the technical field of analytical towers, in particular to an environmentally friendly analytical tower for heating and analyzing a solution mixed with CO2. Background Art

[0002] As global carbon emission controls become increasingly stringent, the shipping industry has generally adopted carbon capture systems based on the absorption method to meet the carbon emission requirements of the International Maritime Organization (IMO). In the field of carbon capture technology, especially in carbon emission control in mobile scenarios such as ships, absorption-based carbon capture devices are widely used. The core process is: first, an organic amine solution is used to absorb CO2 in the exhaust gas to form a rich liquid, and the rich liquid is heated in a decomposition tower to decompose CO2 and then converted into a lean liquid, which circulates to participate in the absorption reaction.

[0003] In addition, diesel engine flue gas usually contains waste heat above 180°C. In existing technologies, this heat is often directly discharged or dissipated through the cooling system and is not effectively utilized. Traditional analysis tower designs do not integrate the flue gas waste heat into the heating process, resulting in energy waste.

[0004] Traditional desorption towers often rely solely on steam heating, which requires additional consumption of high-grade energy (such as electricity or fuel), resulting in low overall energy efficiency and high operating costs. This is not environmentally friendly. The waste heat in the diesel engine flue gas is not effectively recovered, and direct emissions cause energy waste, which is not in line with the green and low-carbon technology trend. The existing packing layout and heat exchange structure design are relatively simple, resulting in uneven heat transfer and loss in hot gas transmission. In addition, the structure of the liquid spraying point is simple, which cannot spray liquid quickly and in all directions. The desorption efficiency and effect need to be improved. In view of this, we propose an environmentally friendly desorption tower for heating and desorption of solutions mixed with CO2. Summary of the Invention

[0020] Compared with the prior art, the present invention provides an environmentally friendly desorption tower for heating and desorption of a solution mixed with CO2, which has the following beneficial effects:

[0021] 1. The environmentally friendly decomposition tower for heating and decomposing a solution mixed with CO2, in order to make the decomposition effect of the decomposition tower body better and more environmentally friendly, is provided with a heating component, in addition to the traditional steam heating method, the flue gas discharged by ship diesel engines and other equipment can be transported to the bottom circular tube and the vertical tube through the flue gas inlet pipe, thereby also providing heat for the solution and promoting CO2 decomposition. The flue gas passes through the top circular tube and the flue gas outlet pipe and is discharged to the spiral tube through the connecting pipe, thereby heating the liquid inlet pipe, thereby preheating the solution, making the subsequent decomposition effect better and more environmentally friendly. In combination with the arrangement of multiple sets of conical baffles, the flue gas is gradually blocked when moving from bottom to top, and the flow is relatively slow, so that the flue gas stays in the vertical tube for a slightly longer time, and uses its own heat to compensate for the heat dissipation along the way, reducing the temperature difference between the bottom and the top of the vertical tube, and cooperates with multiple sets of semicircular baffles to intercept the solution decomposed by the packing layer, thereby increasing the residence time of the solution inside the tower body, and making the decomposition effect better after further reaction.

[0022] 2. The environmentally friendly analysis tower for heating and analyzing a solution mixed with CO2 is provided with a liquid outlet component in order to achieve better analysis effect and higher efficiency. When the solution passes through the liquid inlet pipe and reaches the inside of the multi-head pipe, it is then sprayed into the tower body through multiple groups of circular pipes of different sizes through nozzles. The multiple groups of circular pipes of different sizes will not cause obstructions in the upper and lower directions. At the same time, the setting of multiple groups of nozzles allows the solution to enter the tower body faster and better in all directions, thereby making the subsequent analysis effect better and more efficient. The cross-shaped frame and the filter plate on the rotating rod can prevent impurities from entering the nozzle.

[0023] 3. The environmentally friendly analysis tower used for heating and analyzing a solution mixed with CO2 is provided with a rotating component in order to make the liquid discharge component more effective. When the solution flows through the nozzle, the inclined arc structure of the arc strip is matched, so that the water flow drives the arc cover to rotate, and the rotating rod rotates inside the cross frame, so that the scraping strip rotates to scrape the bottom end of the filter plate to prevent impurities from adhering. At the same time, it drives the V-shaped strip to rotate and scrape the inner wall of the nozzle, which can also prevent impurities from adhering, making the liquid inlet effect better, and then making the liquid discharge component effect better.

[0024] 4. The environmentally friendly analysis tower for heating and analyzing a solution mixed with CO2 is provided with a liquid removal component to make the analysis tower body more practical. When the analyzed CO2 gas gradually rises to the top of the tower body, it will carry some droplets upward together. At this time, the fillers between the circular frame, the trapezoidal frame and the top plate are used to intercept the droplets, so that the droplets gradually adhere and gather and then fall, thereby separating the droplets entrained in the gas, avoiding solution loss and subsequent processing load. The multi-bend shape of the trapezoidal frame increases the area where the droplets adhere, making the liquid removal effect better. The temperature sensor can better monitor the internal temperature of the analysis tower body, and the rotating staircase component is used to facilitate various operations on the analysis tower body after climbing up. In summary, the analysis tower body is more practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] In one embodiment of the present invention, a heating assembly 10 is provided on the tower body 1, and the heating assembly 10 includes a flue gas inlet pipe 101. The flue gas inlet pipe 101 is fixedly installed at the other end of the inner arc-shaped side wall at the bottom end of the tower body 1, and a bottom circular tube 102 is fixedly installed on the outer wall of the flue gas inlet pipe 101. The top of the bottom circular tube 102 is fixedly connected to the bottom end of the vertical tube 103. In addition, there are five groups of vertical tubes 103, and the five groups of vertical tubes 103 are all arranged in a circular array with equal spacing around the center of the circular cross section of the tower body 1, so as to better heat the solution. Heat, the top of the vertical pipe 103 is fixedly connected to the bottom of the top circular pipe 104, and the top circular pipe 104 is fixedly connected to one end of the flue gas outlet pipe 105. The flue gas outlet pipe 105 is fixedly installed inside the arc-shaped side wall of the tower body 1. A spiral tube 106 is provided on the outside of the liquid inlet pipe 2. A connecting pipe 107 is fixedly installed between the other end of the flue gas outlet pipe 105 and the spiral tube 106. A conical baffle 108 is fixedly installed on the inner wall of the vertical pipe 103, and a baffle 109 is fixedly installed inside the conical baffle 108. The cross-section of the top of the conical baffle 108 is The area of ​​the conical shield 108 and the baffle 109 inside the single vertical pipe 103 are smaller than the area of ​​the cross section at the bottom. In addition, there are four groups of conical shields 108 and baffles 109 inside the single vertical pipe 103, and the number of the single conical shields 108 increases gradually from bottom to top (one, two, three and four respectively), and the single conical shields 108 are respectively located between the two groups of packing layers 5. There are six groups of baffles 109 inside the single conical shield 108, and the six groups of baffles 109 are staggered and evenly spaced linear arrays, which increase the residence time of the flue gas inside the tower body 1, further After the step reaction, the analysis effect is better. A semicircular baffle 1010 is fixedly installed on the inner wall of the tower body 1. The semicircular baffle 1010 is located directly below the packing layer 5. The vertical pipe 103 passes through the support plate 4, the packing layer 5, the pressure plate 6 and the semicircular baffle 1010. In addition, the support plate 4, the packing layer 5 and the pressure plate 6 are arranged in four groups, and the four groups of support plates 4, the packing layer 5 and the pressure plate 6 are arranged in a linear array with equal spacing. There are five groups of semicircular baffles 1010, and the five groups of semicircular baffles 1010 are arranged in a linear array with equal spacing.

[0053] When this embodiment is used, after starting the liquid supply device connected to one end of the liquid inlet pipe 2 away from the tower body 1, the solution containing CO2 begins to be transported to the inside of the tower body 1 through the liquid inlet pipe 2. Before the solution enters the tower body 1, the spiral tube 106 in the heating component 10 plays a preheating role. The flue gas discharged by equipment such as ship diesel engines enters from the flue gas inlet pipe 101, and flows through the bottom circular tube 102 and the vertical tube 103 in turn. In the vertical tube 103, the flue gas will exchange heat with the solution in the tower body 1 through the tube wall to heat the solution. The flue gas continues to move forward, passes through the top circular tube 104 and the flue gas outlet pipe 105, and finally flows into the spiral tube 106 through the connecting pipe 107. The spiral tube 106 surrounds the outside of the liquid inlet pipe 2, and the heat of the flue gas is transferred through the spiral tube 106. The liquid inlet pipe 2 is guided to preheat the solution in the pipe to be introduced into the tower body 1, thereby increasing the initial temperature of the solution and creating more favorable conditions for the subsequent analysis process in the tower body 1. After the preheated solution enters the tower body 1, it flows through the packing layer 5 between the support plate 4 and the pressure plate 6. According to Henry's law, the solubility of gas in liquid decreases with increasing temperature. After the solution is heated, the CO2 therein begins to escape from the solution, forming a gas-liquid two-phase countercurrent contact state. The solution flows slowly from top to bottom under the action of gravity, while the escaped CO2 gas flows from bottom to top. The two are in full contact, and CO2 is continuously analyzed from the solution. Inside the vertical pipe 103, multiple groups of conical shields 108 and baffles 109 are provided to further optimize the flue gas heating process. When the flue gas moves from bottom to top, it will gradually be blocked by these conical baffles 108 and baffles 109. Since the cross-sectional area of ​​the top of the conical baffle 108 is smaller than that of the bottom, and the number of the baffles 108 gradually increases from bottom to top, the flow space of the flue gas changes continuously during the rising process, and the flow velocity slows down relatively, thereby extending the residence time in the vertical pipe 103. In this way, the flue gas can use the heat it carries to fully compensate for the heat lost due to heat exchange along the way, effectively reducing the temperature difference between the bottom and the top of the vertical pipe 103, and ensuring the uniformity and continuity of the heating of the solution. At the same time, the semicircular baffle 1010 on the inner wall of the tower body 1 is located directly below the packing layer 5. After the solution has been initially resolved through the packing layer 5, it will be intercepted by the semicircular baffle 1010 when it flows downward. The solution slowly stays at the semicircular baffle 1010, which increases the residence time inside the tower body 1, allowing the solution to have more time to react, further improving the CO2 analysis effect, and finally, the CO2-removed solution is discharged from the drain port 7, and after cooling treatment, it is returned to the absorption system for recycling to achieve solution regeneration (this is the existing equipment of the prior art and will not be repeated); and the CO2-rich gas is discharged from the gas outlet 8 for subsequent collection, treatment or utilization. The traditional heating method is that the steam pipe 3 transports heating steam to the inside of the tower body 1, and the large amount of heat energy carried by the steam is quickly transferred to the solution. The newly added heating method in this application utilizes the flue gas emitted by equipment such as ship diesel engines, which is more energy-saving and environmentally friendly.

[0054] In one embodiment of the present invention, a liquid outlet assembly 11 is provided at the top of the tower body 1. The liquid outlet assembly 11 includes a manifold 111. One end of the liquid inlet pipe 2 located inside the tower body 1 is fixedly connected to one side of the manifold 111. A circular tube 112 is fixedly installed on the other side of the manifold 111. A nozzle 113 is fixedly installed at the bottom of the circular tube 112. The top opening of the nozzle 113 is semicircular. A cross-shaped frame 114 is fixedly installed at the bottom of the nozzle 113. A rotating rod 11 is rotatably installed inside the center of the cross-shaped frame 114. 5. A filter plate 116 is fixedly installed at the bottom of the cross-shaped frame 114, and a rotating rod 115 passes through the center of the filter plate 116. In addition, three groups of circular tubes 112 are provided, and the circular areas enclosed by the three groups of circular tubes 112 in the horizontal direction gradually increase in area from bottom to top. The nozzles 113, cross-shaped frames 114, rotating rods 115 and filter plates 116 on a single group of circular tubes 112 are respectively provided with multiple groups, so that the solution can better and faster enter the interior of the tower body 1 in all directions, thereby making the subsequent analysis effect better.

[0055] When the present embodiment is used, when the solution enters the tower body 1, the solution enters the manifold 111 through the liquid inlet pipe 2. The manifold 111 evenly distributes the solution to multiple groups of circular tubes 112 of different sizes connected thereto. These circular tubes 112 are designed so that the circular areas enclosed in the horizontal direction gradually increase from bottom to top, and do not block each other in the vertical direction, ensuring that the solution can pass through unimpeded. The solution is sprayed out from the nozzle 113 at the bottom end of the circular tube 112. The arrangement of multiple groups of nozzles 113 allows the solution to be sprayed at different angles and directions. It enters the interior of the tower body 1 in an all-round and rapid manner, greatly increasing the contact area between the solution and the heating steam and the rising CO2 gas, thereby improving the analysis efficiency and effect. At the bottom of the nozzle 113, the filter plate 116 installed on the cross frame 114 and the rotating rod 115 plays the role of intercepting impurities. During the solution reaction process, some solid particles or other impurities may be carried upward with the airflow. The filter plate 116 can effectively intercept these impurities and prevent them from entering the interior of the nozzle 113, avoiding clogging of the nozzle 113, and ensuring the stability and smoothness of the solution injection.

[0056] In one embodiment of the present invention, a rotating assembly 12 is provided on the nozzle 113, and the rotating assembly 12 includes an arc cover 121, and the arc cover 121 is fixedly installed on the top of the rotating rod 115, and the arc-shaped outer wall of the arc cover 121 is fixedly installed with an arc bar 122. The arc cover 121 is provided with multiple groups, and the arc bar 122 on a single group of arc covers 121 is provided with multiple groups. The arc outer wall at the bottom end of the rotating rod 115 is fixedly installed with a scraper bar 123, and the top of the scraper bar 123 slides and fits the bottom of the filter plate 116. There are three groups of scraper bars 123 to prevent impurities from adhering to the filter plate 116. In addition, one end of the arc outer wall at the top of the rotating rod 115 is fixedly installed with a V-shaped bar 124, and the other end of the V-shaped bar 124 slides and fits the arc inner wall of the nozzle 113. There are three groups of V-shaped bars 124 on the single group of rotating rods 115 to prevent impurities from adhering to the inside of the nozzle 113.

[0057] When this embodiment is used, the existence of the rotating assembly 12 further ensures the stable operation of the liquid outlet assembly 11. When the solution flows through the nozzle 113, since the arc strip 122 adopts an inclined arc structure and the top opening of the nozzle 113 is semicircular, the solution acts downward on the half area of ​​the arc cover 121. Therefore, when the impact force generated by the downward flow of the solution acts on the arc strip 122, it can drive the arc cover 121 to rotate. The arc cover 121 is fixedly connected to the rotating rod 115, so that the rotating rod 115 rotates inside the cross frame 114. During the rotation of the rotating rod 115 The scraper 123 at the bottom will rotate synchronously and continuously scrape the bottom of the filter plate 116. Even if a small amount of impurities adhere to the filter plate 116, the scraping of the scraper 123 can remove them to prevent the accumulation of impurities and affect the filtering effect. At the same time, the V-shaped bar 124 at the top of the rotating rod 115 will scrape the inner wall of the nozzle 113 as the rotating rod 115 rotates, preventing impurities in the solution from adhering to and crystallizing on the inner wall of the nozzle 113, ensuring that the internal channel of the nozzle 113 is unobstructed, maintaining good liquid inlet and spraying effects, and enabling the entire liquid outlet component 11 to work stably and efficiently for a long time.

[0058] In one embodiment of the present invention, a liquid removal assembly 13 is further provided at the top of the tower body 1. The liquid removal assembly 13 includes a circular frame 131. The circular frame 131 is fixedly installed on the arc-shaped inner wall at the top of the tower body 1. A ladder frame 132 is fixedly installed inside the bottom end of the circular frame 131. A top plate 133 is fixedly installed on the top of the circular frame 131. Fillers are also provided inside the circular frame 131. There are multiple groups of ladder frames 132, and the ladder frames 132 are located above the manifold 111, which can separate the droplets entrained in the gas to avoid solution loss and subsequent processing load.

[0059] When this embodiment is used, during the analysis process, when the analyzed CO2 gas gradually rises to the top of the tower body 1, it will inevitably carry some droplets upward. At this time, the liquid removal component 13 begins to work. The circular frame 131, the trapezoidal frame 132 and the top plate 133 at the top of the tower body 1 are filled with special fillers. When the CO2 gas carrying droplets passes through, the droplets will collide and adsorb with the filler, and gradually adhere to the surface of the filler. As the droplets continue to gather, they will eventually fall due to gravity, thereby realizing the separation of droplets entrained in the gas, effectively avoiding solution loss, and reducing the load of subsequent gas processing. The multi-bend shape and multi-group design of the trapezoidal frame 132 greatly increases the area for droplet attachment, further improving the liquid removal effect.
