Example 1
Referring to fig. 1, the present embodiment provides a stripping reboiler 100a, which includes a housing 190, a stripping gas pipe 110, a lean solution overflow pipe 140 for outputting lean solution, a heating component 120, and a stripping compartment 130 disposed in the housing 190 and filled with a filler, wherein the heating component 120 is disposed in the housing 190 and disposed outside the stripping compartment 130. The top of the stripping compartment 130 is provided with a gas-liquid channel 164 communicating with the space where the heating element 120 is located, and the outlet end 112 of the stripping gas pipe 110 and the inlet end 142 of the lean liquid overflow pipe 140 are both arranged at the bottom inside the stripping compartment 130.
The stripping compartment 130 is disposed in the stripping reboiler 100a, so as to complete the stripping process, reduce the volume of the apparatus, and facilitate the installation and transportation of the apparatus. The packing is filled in the stripping compartment 130, so that the contact area of the gas and the liquid is increased, the gas-liquid separation effect is improved, the components to be separated in the regenerated liquid to be regenerated in the stripping reboiler 100a are better separated, and the purity of the regenerated liquid output from the lean liquid overflow pipe 140 is improved. Specifically, the liquid entering the stripping reboiler 100a is warmed by the stripping reboiler 100a so that the components to be separated therein enter the gas phase, the purity of the liquid phase components is raised to be regenerated, and the liquid outputted from the lean liquid overflow pipe 140 is referred to as a regenerated liquid.
Specifically, the packing material filled in the stripping compartment 130 may be pall rings or raschig rings, etc. Preferably, the high-efficiency filler with the specific surface area larger than 300, such as 250Y-shaped filler or theta-ring, can increase the contact area of gas and liquid phases to a larger extent, and strengthen the stripping process.
Specifically, the stripping gas pipeline 110 is used for conveying stripping gas in the gas stripping process, and after the temperature of the stripping gas pipeline 110 is raised through the space where the heating component 120 is located, components to be separated in liquid in the gas stripping process are favorably separated, so that the purity of the regenerated liquid is improved. The heating unit 120 has the same structure and operation principle as the existing heat exchanger for heating the gas phase and the liquid phase, and will not be described in detail herein.
Specifically, the lean liquid overflow pipe 140 is used for conveying the regenerated liquid out of the stripping reboiler 100a, the inlet end 142 of the lean liquid overflow pipe 140 is arranged at the bottom of the stripping compartment 130, extends from the inlet end 142 to the top of the stripping compartment 130 and is generally not higher than the liquid level of the liquid in the stripping reboiler 100a, and the liquid in the stripping compartment 130 enters the inlet end 142 of the lean liquid overflow pipe 140 and is conveyed out of the stripping reboiler 100a by the driving force of the liquid level difference. After bending at the top of the stripping compartment 130, the lean liquid overflow pipe 140 extends out from the side wall of the stripping compartment 130, and the regenerated liquid is transported to the next section.
Further, the inlet end 142 of the lean liquid overflow pipe 140 is lower than the outlet end 112 of the stripping gas conduit 110. In order to prevent the stripping gas output from the stripping gas conduit 110 from entering the lean liquid overflow pipe 140, it is necessary to make the position of the inlet end 142 of the lean liquid overflow pipe 140 lower than the outlet end 112 of the stripping gas conduit 110.
Further, a manhole 170 is provided at the top of the stripping compartment 130. The provision of the manhole 170 may facilitate filling of the packing and maintenance of the equipment by the operator.
Further, referring to fig. 1 and 2, the gas-liquid passage 164 is located in the stripping chamber 130 near the baffle 160 at one end of the heating element 120. The stripping compartment 130 may be disposed at one end of the housing 190, the stripping compartment 130 being defined by a top wall, a bottom wall, side walls of the housing 190 and the baffle 160, with the gas-liquid passage 164 being located at an end of the baffle 160 near the top of the housing 190. Specifically, the gas-liquid passage 164 is a cavity provided in the baffle 160, and both the liquid within the housing 190 and the stripping gas conduit 110 may pass through the gas-liquid passage 164 into the stripping compartment 130, with the gas within the stripping compartment 130 exiting the stripping compartment 130 from the gas-liquid passage 164. In addition, the baffle 160 is in a sealed plate-like configuration elsewhere in the gas-liquid passage 164, allowing liquid within the housing 190 to enter the stripping compartment 130 from the gas-liquid passage 164.
Further, referring again to fig. 1, a gas distributor 180 is disposed at the bottom of the stripping compartment 130, and the inlet of the gas distributor 180 communicates with the outlet end 112 of the stripping gas conduit 110. The gas distributor 180 is arranged to uniformly distribute the gas conveyed by the stripping gas pipeline 110 in the stripping compartment 130 after outputting the gas, and better contact the liquid, so as to promote the stripping process to be better carried out and achieve the aim of improving the purity of the regenerated liquid.
Further, referring to fig. 1 and 3, the gas distributor 180 includes a branch pipe 181 and a dispersion ball 182, the branch pipe 181 is communicated with the outlet end 112 of the gas stripping gas pipe 110, the dispersion ball 182 is disposed at one end of the branch pipe 181 near the bottom wall of the gas stripping compartment 130, and the dispersion ball 182 is higher than the inlet end 142 of the lean liquid overflow pipe 140. The gas output from the stripping gas conduit 110 enters the manifold 181 of the gas distributor 180 and enters the liquid in the stripping compartment 130 from the dispersion balls 182, creating bubbles which enhance the contact of the gas with the liquid, allowing the stripping action to be more efficient.
It should be noted that, the working principle of the stripping reboiler 100b provided in this embodiment is as follows: after the temperature of the stripping gas pipe 110 is raised, the liquid enters the bottom of the stripping compartment 130 through the gas-liquid channel 164, is used for providing the stripping gas, and the liquid needing to be regenerated enters the shell 190 and then enters the stripping compartment 130 through the gas-liquid channel 164. The gas and liquid are fully contacted in the gas stripping compartment 130 filled with the filling material, and the introduction of the gas stripping gas reduces the partial pressure of the components to be separated in the gas phase in the liquid, promotes the components to be separated from the liquid and enter the gas phase, and improves the separation efficiency of the components to be separated.
Example 2
Referring to fig. 4, the stripping reboiler 100b according to the present embodiment has the same principle and technical effects as those of embodiment 1, and for brevity, reference is made to the corresponding contents of embodiment 1. Except that the stripping reboiler 100b provided in this embodiment further includes a baffle 150.
Specifically, referring to fig. 5, a baffle 150 is disposed between the stripping compartment 130 and the heating element 120, a gas phase channel 152 is formed between the top of the baffle 150 and the top wall of the housing 190, and a liquid phase channel 154 is formed between the bottom of the baffle 150 and the bottom wall of the housing 190. The stripping gas line 110 passes through the gas phase passage 152 at the top of the baffle 150 and then through the baffle 160 to the stripping compartment 130. Liquid in the shell 190 and outside the stripping compartment 130 passes through the liquid phase channel 154 at the bottom of the baffle 150 and then enters the stripping compartment 130 through the gas-liquid channel 164 on the baffle 160, so that back mixing is reduced in the process, and the liquid entering the shell 190 is heated by the heating component 120 for a certain time and then enters the stripping compartment 130 for stripping, instead of entering the stripping compartment 130 at a high liquid level as in embodiment 1, the liquid at the bottom is heated for a longer time, and the temperature difference is larger, which is unfavorable for the stripping process. Thus, the provision of the baffle 150 reduces the occurrence of back mixing and improves the stripping effect to some extent.
Referring to fig. 6, the gas-liquid channel 164 is a plurality of strip-shaped holes. The gas-liquid passage 164 is provided in the form of a plurality of strip-shaped holes instead of the cavity in embodiment 1, which enhances the gas-liquid contact during the gas and liquid passing through the gas-liquid passage 164, and is beneficial to the gas stripping process and the recovery liquid with higher purity.
Further, a through hole 162 for the air-stripping gas conduit 110 to enter the stripping compartment 130 is also provided at the end of the baffle 160 near the top of the housing 190. Specifically, the size of the through-holes 162 matches the size of the stripper gas conduit 110.
Further, in conjunction with fig. 5 and 6, the width of the gas-liquid channel 164 is greater than the width of the gas-phase channel 152. The gas-liquid channel 164 is a channel through which gas and liquid flow, and the gas-phase channel 152 is a channel through which only gas phase flows, so that the flow space provided by the gas-liquid channel 164 is larger than the flow space provided by the gas-phase channel 152. In addition, the larger the flow space provided by the gas-liquid channel 164, the flow rate of the gas phase and the liquid phase can be reduced to a certain extent, the contact time of the gas phase and the liquid phase can be increased, and the stripping effect can be enhanced.
It should be noted that, the working principle of the stripping reboiler 100b provided in this embodiment is as follows: after the temperature of the gas in the stripping gas pipeline 110 is raised, the gas enters the stripping compartment 130 through the gas phase channel 152 and the gas-liquid channel 164, and is bubbled through the dispersing ball 182 end of the distributor 180 and enters the liquid phase; liquid enters the housing 190 to warm up and enters the stripping compartment 130 through the liquid phase passage 154 and the gas-liquid passage 164; the gas-liquid phase in the packing layer of the stripping compartment 130 is fully contacted, the introduction of the stripping gas reduces the partial pressure of the components to be separated in the gas phase in the liquid, promotes the separation of the components to be separated from the liquid, and the regenerated liquid with higher purity is led out from the lean liquid overflow pipe 140.
Referring to fig. 7, the present invention further provides an absorption apparatus 200, which includes an absorption tower 210, a rectifying column 220 and a stripping reboiler 100b, wherein the stripping reboiler 100b is communicated with the bottom end of the rectifying column 220, and the outlet end 144 of the lean solution overflow pipe 140 is communicated with the lean solution inlet 216 of the absorption tower 210.
Specifically, the raw material mixed gas enters from the raw material gas inlet 212 of the absorption tower 210, the absorbent enters the absorption tower 210 from the lean solution inlet 216, the absorbent absorbs the easily absorbable components in the raw material gas in the absorption tower 210, the absorbed rich solution is output from the rich solution outlet 214 to enter the rich solution inlet 222 of the rectification column 220, the regeneration process of the absorbent is performed in the rectification column 220, the liquid at the bottom of the rectification column 220 enters the stripping reboiler 100b to complete the stripping process, the purer absorbent is output from the lean solution overflow pipe 140 as the lean solution, and is conveyed to the absorption tower 210 by the lean solution pump 250 for the next stage of absorption process.
The lean-rich liquid heat exchanger 240 may be added to exchange heat between the lean liquid output from the stripping reboiler 100b and the rich liquid output from the rich liquid outlet 214. The heat source inlet 122 is a medium for raising the temperature to be fed to the gas-stripping reboiler 100b, and the gas-stripping reboiler 100b has the same heating system as the conventional one. In addition, the absorption column 210 and the rectification column 220 are the same as the existing structure and working principle, and the process flow can be optimized for improving the separation efficiency.
It should be noted that, in the regeneration process of the absorbent, the absorption device 200 adds the stripping compartment 130 filled with the filler, enhances the separation of the absorbent and the easily absorbable component in the stripping process, improves the purity of the regenerated lean solution, and ensures the absorption efficiency in the absorption process of the next stage in comparison.
In summary, the present invention provides a stripping reboiler, which performs a stripping process in a stripping compartment filled with a packing, and the stripping compartment is disposed in a cavity of the stripping reboiler, so that the volume of the device is reduced while ensuring a gas-liquid separation effect; the inlet end of the lean solution overflow pipe is lower than the outlet end of the gas stripping pipeline, so that the gas for gas stripping output from the gas stripping pipeline is prevented from entering the lean solution overflow pipe; the gas distributor comprises branch pipes and dispersion balls, and the contact between the gas and the liquid is enhanced by generating bubbling, so that the stripping action is more effectively performed; the arrangement of the guide plate reduces the generation of back mixing, improves the stripping effect to a certain extent, and ensures that the purity of the regenerated liquid is higher.
