Description

Technical Field

[0001] The present disclosure relates to the field of gas purification, and in particular to a regeneration pipeline system for an adsorption pipeline. Background Art

[0002] The gas purification process is a common raw gas treatment process in the fields of metallurgy, energy, chemical industry, environmental protection, etc. As a common gas purification process, temperature swing adsorption mostly adopts the operation methods of normal temperature adsorption and temperature rise desorption. The current temperature swing adsorption regeneration is divided into reduced pressure regeneration and isobaric regeneration. The temperature swing adsorption of the isobaric closed cycle regeneration system includes three operation processes: adsorption, heating, and cooling. However, since the regeneration pipeline and the adsorption pipeline are in an independent state during operation, and the regeneration pipeline is always closed and circulated. Therefore, during the heating process, the heated regenerated gas directly enters the adsorption tower, and the pressure in the adsorption tower will exceed the normal working pressure. At this time, the safety valve installed on the adsorption tower may trip, which is not conducive to the normal operation of the system. Summary of the invention

[0028] The gas purification process is a common raw gas treatment process in the fields of metallurgy, energy, chemical industry, environmental protection, etc. As a common gas purification process, temperature swing adsorption utilizes the characteristic that the equilibrium adsorption amount of the adsorbent decreases with increasing temperature. It adopts the operation method of normal temperature adsorption and temperature rise desorption. The current temperature swing adsorption regeneration is divided into reduced pressure regeneration and isobaric regeneration. The temperature swing adsorption of the isobaric closed cycle regeneration system includes three operation processes: adsorption, heating, and cooling. Since the regeneration pipeline and the adsorption pipeline are in an independent state when working, and the regeneration pipeline is always closed and circulated. Therefore, during the heating process, the heated regenerated gas directly enters the adsorption tower, and the pressure in the adsorption tower will exceed the normal working pressure. At this time, the safety valve installed on the adsorption tower may trip, which is not conducive to the normal operation of the system.

[0029] In an embodiment of the present disclosure, a regeneration pipeline system for an adsorption pipeline is provided. By adding a balancing pipeline between the gas-liquid separator and the pre-filter, the high-pressure regeneration gas in the regeneration pipeline can flow to the adsorption pipeline through the balancing pipeline, and enter the adsorption tower in the adsorption state for adsorption again, thereby reducing the amount of the regeneration pipeline entering the adsorption tower in the regeneration state, reducing the pressure in the adsorption tower in the regeneration state, and avoiding the adsorption tower in the regeneration state from being unable to operate normally due to excessive pressure in the tower.

[0030] Figure 1 The schematic diagram of the regeneration pipeline system for the adsorption pipeline in the embodiment of the present disclosure is shown in FIG. Figure 1 In the example, the adsorption pipeline 10 includes two adsorption towers 12 connected in parallel via a first parallel pipeline 11; the two adsorption towers 12 are alternately in an adsorption state and a regeneration state.

[0031] Exemplarily, an adsorption control valve group 111 is provided on the first parallel pipeline 11 of each adsorption tower 12 in the adsorption pipeline 10, and the adsorption control valve group 111 includes a first adsorption control valve 1111 and a second adsorption control valve 1112 respectively arranged at the upstream and downstream of the adsorption pipeline 10; the opening and closing states of the two adsorption control valve groups 111 are opposite. Further exemplarily, the adsorption pipeline 10 also includes a pre-filter 13 and a post-filter 14; the pre-filter 13 is arranged at the upstream position of the first parallel pipeline 11, and the post-filter 14 is arranged at the downstream position of the first parallel pipeline 11. It can be understood by those skilled in the art that the direction of flow from the inlet to the outlet of the adsorption pipeline 10 is the upstream of the adsorption pipeline 10, and the direction of flow from the outlet to the inlet of the adsorption pipeline 10 is the downstream of the adsorption pipeline 10.

[0032] exist Figure 1 In the example, the regeneration pipeline 20 system includes a regeneration pipeline 20, a balancing pipeline 30 and a regeneration control valve group 40. The regeneration pipeline 20 includes a cooler 21, a gas-liquid separator 22, a supercharger 23, a heater 24 and a second parallel pipeline 25 connected in series in sequence; the two adsorption towers 12 are also connected in parallel through the second parallel pipeline 25, and then connected in series between the heater 24 and the cooler 21 in the regeneration pipeline 20.

[0033] The first end 31 of the balancing pipeline 30 is connected between the gas-liquid separator 22 and the booster 23 in the regeneration pipeline 20, and the second end 32 is connected to the upstream position of the first parallel pipeline 11 in the adsorption pipeline 10. It can be understood by those skilled in the art that by adding a balancing pipeline 30 between the gas-liquid separator 22 and the pre-filter 13, the high-pressure regeneration gas in the regeneration pipeline 20 can flow to the adsorption pipeline 10 through the balancing pipeline 30, and enter the adsorption tower 12 in the adsorption state for adsorption again, thereby reducing the amount of the regeneration pipeline 20 entering the adsorption tower 12 in the regeneration state, reducing the pressure in the adsorption tower 12 in the regeneration state, and avoiding the adsorption tower 12 in the regeneration state from being unable to operate normally due to excessive pressure in the tower.

[0034] Exemplarily, the flow direction of the adsorption pipeline 10 is opposite to the flow direction of the regeneration pipeline 20, that is, the upstream and downstream of the regeneration pipeline 20 are opposite to the upstream and downstream of the adsorption pipeline 10. Further exemplarily, the connection point between the first end 31 of the balancing pipeline 30 and the regeneration pipeline 20 is located downstream of the cooler 21 and the gas-liquid separator 22, and upstream of the supercharger 23. The advantage of such a setting is that the regeneration gas flowing into the balancing pipeline 30 from the adsorption tower 12 in the regeneration state is the regeneration gas cooled by the cooler 21, and the dry gas after the liquid is separated by the gas-liquid separator 22. In this way, it can be avoided that the regeneration gas entering the adsorption pipeline 10 through the balancing pipeline 30 causes the internal pressure of the adsorption tower 12 to increase due to excessive temperature. Secondly, it can be avoided that the adsorbent in the adsorption tower 12 is reduced in strength or even pulverized due to the liquid contained in the regeneration gas entering the adsorption pipeline 10 through the balancing pipeline 30, thereby improving the adsorption effect of the adsorption tower 12.

[0035] Secondly, the second end 32 of the balancing pipeline 30 is connected to the upstream position of the pre-filter 13. The advantage of such a configuration is that the pre-filter 13 can pre-filter the regeneration gas in the regeneration pipeline 20 that flows to the adsorption pipeline 10 through the balancing pipeline 30, so as to improve the purity of the gas entering the adsorption tower 12, reduce the working intensity of the adsorption tower 12, and increase the service life of the adsorbent in the adsorption tower 12.

[0036] The regeneration control valve group 40 is configured to connect the adsorption tower 12 in the regeneration state to the regeneration pipeline 20 to connect to the first end 31 of the balancing pipeline 30, and disconnect the other adsorption tower 12 in the adsorption state from the regeneration pipeline 20; and the first parallel pipeline 11 connects the second end 32 of the balancing pipeline 30 to the other adsorption tower 12 in the adsorption state, and disconnects the adsorption pipeline 10 from the adsorption tower 12 in the regeneration state.

[0037] Exemplarily, the regeneration control valve group 40 is provided on the second parallel pipeline 25 of each adsorption tower 12 in the regeneration pipeline 20, and the regeneration control valve group 40 includes a first regeneration control valve 41 and a second regeneration control valve 42 respectively arranged upstream and downstream of the regeneration pipeline 20; wherein the second parallel pipeline 25 does not pass through the adsorption control valve group 111; the opening and closing states of the two regeneration control valve groups 40 are opposite; and the opening and closing states between the adsorption control valve group 111 and the regeneration control valve group 40 of each adsorption tower 12 are opposite.

[0038] For example, in Figure 1In the example, when one of the two adsorption towers 12 is in the adsorption state and the other is in the regeneration state; the first adsorption control valve 1111 and the second adsorption control valve 1112 on the first parallel pipeline 11 of the adsorption tower 12 in the adsorption state are in the conduction state, and the first regeneration control valve 41 and the second regeneration control valve 42 on the second parallel pipeline 25 of the adsorption tower 12 in the adsorption state are in the closed state; and the first adsorption control valve 1111 and the second adsorption control valve 1112 on the first parallel pipeline 11 of the other adsorption tower 12 in the regeneration state are in the closed state, and the first regeneration control valve 41 and the second regeneration control valve 42 on the second parallel pipeline 25 of the other adsorption tower 12 in the regeneration state are in the conduction state. At this time, because the second parallel pipeline 25 does not pass through the adsorption control valve group 111, the adsorption control valve group 111 and the regeneration control valve group 40 on the same adsorption tower 12 do not affect each other. When the states of the two adsorption towers 12 are alternating, the opening and closing states of the adsorption control valve group 111 and the regeneration control valve group 40 of the two adsorption towers 12 are opposite.

[0039] Exemplarily, the regeneration pipeline 20 system also includes a second controller (not shown in the figure), which is connected to the adsorption control valve group 111 and the regeneration control valve group 40 to control the opening and closing of the adsorption control valve group 111 and the regeneration control valve group 40 to achieve the two adsorption towers 12 being alternately in the adsorption state and the regeneration state.

[0040] exist Figure 1 In the example, the balancing pipeline 30 is provided with a regulating control valve 33 with adjustable opening. Further exemplarily, the regeneration pipeline 20 system further includes a first controller (not shown in the figure), which is connected to the regulating control valve 33 to control the conduction degree of the regulating control valve 33. In another embodiment, the first controller and the second controller can be the same controller.

[0041] It is understandable to those skilled in the art that the balancing pipeline 30 can divert part of the gas in the regeneration pipeline 20 to the adsorption tower 12 in the adsorption state on the adsorption pipeline 10 when the regeneration pipeline 20 is in a state of high temperature and high pressure, so as to reduce the amount of the regeneration pipeline 20 entering the adsorption tower 12 in the regeneration state, thereby avoiding excessive pressure inside the adsorption tower 12 in the regeneration state. It is also possible that when the gas flow rate in the regeneration pipeline 20 is small, the balancing pipeline 30 diverts part of the gas upstream of the adsorption pipeline 10 to the regeneration pipeline 20 to increase the gas pressure inside the regeneration pipeline 20, meet the gas flow rate requirement for desorbing the adsorbent inside the adsorption tower 12 in the regeneration state, and improve the desorption effect of the adsorbent.

[0042] exist Figure 1 In the example, the regeneration pipeline 20 is provided with a first temperature detector 26 located between the heater 24 and the two adsorption towers 12, a second temperature detector 27 located between the cooler 21 and the two adsorption towers 12, and a third temperature detector 28 located between the cooler 21 and the gas-liquid separator 22. Further exemplarily, the first temperature detector 26, the second temperature detector 27 and the third temperature detector 28 are all connected to the second controller; the second controller is connected to the cooler 21 and the heater 24. The second controller adjusts the state of the cooler 21 and the heater 24 in real time through the detection results of the first temperature detector 26, the second temperature detector 27 and the third temperature detector 28, so that the regeneration gas entering the adsorption tower 12 in the regeneration state is in a state where the parameters meet the desorption requirements.

[0043] In summary, a regeneration pipeline system for an adsorption pipeline is provided in an embodiment of the present disclosure, wherein the adsorption pipeline includes two adsorption towers connected in parallel through a first parallel pipeline; the two adsorption towers are alternately in an adsorption state and a regeneration state; the regeneration pipeline system includes a regeneration pipeline, a balancing pipeline, and a regeneration control valve group. The regeneration pipeline includes a cooler, a gas-liquid separator, a supercharger, a heater, and a second parallel pipeline connected in series in sequence; the two adsorption towers are also connected in parallel through the second parallel pipeline and then connected in series between the heater and the cooler in the regeneration pipeline. The first end of the balancing pipeline is connected between the gas-liquid separator and the supercharger in the regeneration pipeline, and the second end is connected upstream of the first parallel pipeline in the adsorption pipeline. The regeneration control valve group is configured to connect the adsorption tower in the regeneration state to the regeneration pipeline to connect to the first end of the balancing pipeline, and disconnect the other adsorption tower in the adsorption state from the regeneration pipeline; and the first parallel pipeline connects the second end of the balancing pipeline to the other adsorption tower in the adsorption state, and disconnects the adsorption pipeline from the adsorption tower in the regeneration state.

[0044] The disclosed embodiment adds a balancing pipeline between the gas-liquid separator and the pre-filter, so that the high-pressure regeneration gas in the regeneration pipeline can flow to the adsorption pipeline through the balancing pipeline and enter the adsorption tower in the adsorption state for adsorption again, thereby reducing the amount of gas entering the adsorption tower in the regeneration state through the regeneration pipeline, reducing the pressure in the adsorption tower in the regeneration state, and avoiding the adsorption tower in the regeneration state from being unable to operate normally due to excessive pressure in the tower.
