[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figure 1 As shown, the sodium coke system for coupled adsorbent regeneration according to an embodiment of the present invention includes: a regeneration component 1, a first heat exchange component 2, a drying component 3 and a silo component 4.

[0032] The regeneration component 1 includes a regeneration tower 11 and a heating component 12. The regeneration tower 11 includes a preheating section 111, a heating section 112 and a cooling section 113 arranged in sequence along the flow direction of the adsorbent. The heating component 12 is connected to the heating section 112 to heat the adsorbent in the heating section 112 of the regeneration tower 11. The hot side inlet of the first heat exchange component 2 is used to pass steam, and the first heat exchange component 2 is connected to the heating component 12, so that in the first heat exchange component 2, the heating medium in the heating component 12 exchanges heat with the steam. The drying component 3 includes a drying element 31 and a second heat exchange component 32. The cold side inlet of the second heat exchange component 32 is connected to the drying element 31, and the hot side inlet of the second heat exchange component 32 is connected to the hot side outlet of the first heat exchange component 2, so that in the second heat exchange component 32, the steam after heat exchange exchanges heat with the dry gas, and the dry medium after heat exchange is passed into the drying element 31. The silo component 4 is connected to the drying element 31, so that the dry gas discharged from the drying element 31 is used to dry the material in the silo component 4.

[0033] Specifically, Figure 1 As shown, the preheating section 111, the heating section 112 and the cooling section 113 are arranged in sequence from top to bottom, wherein the preheating section 111 is used to preheat the adsorbent, the heating section 112 uses the heat energy (i.e., the heating medium) provided by the heating component 12 to regenerate the adsorbent, and the cooling section 113 is used to cool the regenerated adsorbent. In the first heat exchange component 2, the heating medium in the heating component 12 exchanges heat with the steam so that the heat of the steam is transferred to the heating medium, thereby realizing the recovery and utilization of heat energy. In other words, through the indirect heat exchange between the steam and the heating medium, the thermal energy of the steam can be fully utilized, the demand for electrical energy can be reduced, the energy consumption can be reduced, and the energy efficiency of the system can be improved.

[0034] The drying component 3 includes a drying element 31 and a second heat exchange component 32. The cold side inlet of the second heat exchange component 32 is connected to the drying element 31, and the hot side inlet is connected to the hot side outlet of the first heat exchange component 2. In the second heat exchange component 32, the steam after heat exchange exchanges heat with the drying gas again, and the heat energy is transferred to the drying gas, and then the drying gas is sent to the drying element 31 for drying. In this way, the secondary utilization of steam heat energy is achieved, that is, the heat of the steam is first transferred to the heating medium, and then the heat of the steam is transferred to the drying gas, thereby improving the efficiency of heat energy utilization and reducing energy consumption in the heating regeneration section and the drying process.

[0035] The silo assembly 4 is connected to the drying element 31, and the drying gas discharged from the drying element 31 is used to dry the material in the silo assembly 4, so as to further recycle the heat in the drying gas and dry the material in the silo 41, thereby improving the processing efficiency and quality of the material and reducing the energy consumption of the overall system.

[0036] Therefore, the sodium coke system coupled with adsorbent regeneration in the embodiment of the present invention recovers the waste heat from the adsorbent regeneration process and uses it in the drying process of the sodium coke salt making system, thereby realizing multiple utilization of thermal energy, greatly improving energy utilization and reducing energy costs. In addition, by optimizing the utilization of thermal energy, the regeneration effect of the adsorbent and the efficiency of sodium coke salt making are guaranteed, thereby improving the overall production efficiency.

[0037] In some embodiments, the heating component 12 includes a heating circulation pipeline 121 and a heating heat exchanger 122, the heating circulation pipeline 121 is connected to the heating heat exchanger 122, the heating heat exchanger 122 is placed in the heating section 112, and the cold side inlet and cold side outlet of the first heat exchange component 2 are connected to the heating circulation pipeline 121.

[0038] It is understood that the heating circulation pipeline 121 is a closed piping system for circulating a heating medium, such as gas, oil or other suitable heating fluid. The heating heat exchanger 122 is a heat exchange device, which is installed in the heating section 112 of the regeneration tower 11 and is used to transfer the heat of the heating medium to the adsorbent by indirect heat exchange. The cold side inlet and the cold side outlet of the first heat exchange component 2 are respectively connected to the heating circulation pipeline 121, so that in the first heat exchange component 2, the heating circulation pipeline 121 absorbs heat from the steam and is used for the adsorbent regeneration process in the regeneration section.

[0039] The heating medium in the heating circulation pipeline 121 is pumped to the heating heat exchanger 122, and contacts and transfers heat to the adsorbent in the heating section 112. After the adsorbent absorbs heat in the heating section 112, its temperature rises, thereby ensuring the desorption effect of the adsorbent. In other words, the first heat exchange component 2 uses the steam passed into it to exchange heat with the heating medium in the heating circulation pipeline 121, so that the heating medium reaches the temperature required for adsorbent regeneration, thereby reducing the use of electric heating to heat the heating medium and reducing energy consumption.

[0040] In some embodiments, the first heat exchange component 2 includes a first heat exchanger 21 and a heat exchange pipeline, the cold side inlet and cold side outlet of the first heat exchanger 21 are connected to the heating circulation pipeline 121, and the heat exchange pipeline connects the hot side outlet of the first heat exchanger 21 and the hot side inlet of the second heat exchange component 32.

[0041] It is understandable that if Figure 1 As shown, when the heating medium in the heating circulation pipeline 121 passes through the first heat exchanger 21, the heating medium exchanges heat with the steam, so that the heating medium is heated and reaches the temperature required by the heating section 112 of the regeneration tower 11. The steam after heat exchange is then transported to the second heat exchange component 32 through the heat exchange pipeline to transfer heat to the drying gas. Therefore, the steam after heat exchange in the first heat exchanger 21 is then transferred to the second heat exchange component 32, which can realize the cascade utilization of thermal energy and improve the energy efficiency of the overall system.

[0042] In addition, the heat exchange pipeline design between the first heat exchanger 21 and the second heat exchange assembly 32 provides flexibility in system operation and can adjust heat distribution according to actual needs.

[0043] In some embodiments, the sodium coke system for coupled adsorbent regeneration of an embodiment of the present invention also includes a first preheating component 5, the cold side inlet and cold side outlet of the first preheating component 5 are connected to the heating circulation pipeline 121, and the first preheating component 5 is located upstream of the first heat exchanger 21 in the flow direction of the heating medium, the hot side inlet of the first preheating component 5 is connected to the hot side outlet of the first heat exchanger 21, and the hot side outlet of the first preheating component 5 is connected to the hot side inlet of the second heat exchange component 32.

[0044] It is understandable that if Figure 1 As shown, after the steam passes through the first heat exchanger 21, its temperature will drop. The first preheating component 5 can use this part of heat to preheat the heating medium in the heating circulation pipeline 121. The hot side inlet of the first preheating component 5 receives the steam from the first heat exchanger 21, and the steam releases the remaining heat in the first preheating component 5 to preheat the heating medium in the heating circulation pipeline 121. In this way, the first preheating component 5 can recover and utilize the heat that may have been wasted, thereby improving the thermal efficiency of the entire system.

[0045] That is to say, the addition of the first preheating component 5 enables the heating medium to be preheated before entering the first heat exchanger 21 , thereby achieving higher thermal efficiency in the first heat exchanger 21 .

[0046] In some embodiments, the heating component 12 includes a heating circulation pipeline 121 and a heating heat exchanger 122, the first preheating component 5 includes a first preheater 51 and a first preheating pipeline 52, the cold side inlet and the cold side outlet of the first preheater 51 are connected to the heating circulation pipeline 121, the first preheating pipeline 52 connects the hot side inlet of the first preheater 51 and the hot side outlet of the first heat exchanger 21, the first preheating pipeline 52 connects the hot side outlet of the first preheater 51 and the hot side inlet of the second heat exchange component 32, and the first preheating pipeline 52 is connected in parallel with the heat exchange pipeline.

[0047] It is understandable that if Figure 1 As shown, the first preheater 51 is used to preheat the heating medium in the heating circulation pipeline 121. The first preheating pipeline 52 is used to connect the first preheater 51 with the first heat exchanger 21 and the second heat exchange component 32 to ensure that the hot fluid can flow effectively between these components. The cold side inlet and the cold side outlet of the first preheater 51 are connected to the heating circulation pipeline 121 so that the heating medium is preheated before entering the first heat exchanger 21. The first preheating pipeline 52 connects the hot side inlet of the first preheater 51 with the hot side outlet of the first heat exchanger 21, so that after the steam releases heat in the first heat exchanger 21, it can continue to preheat the heating medium in the first preheater 51.

[0048] The first preheating pipeline 52 is connected in parallel with the heat exchange pipeline, and the steam can flow to the first preheater 51 or the second heat exchange component 32 according to different needs. Therefore, by preheating the heating medium through the first preheater 51, the thermal efficiency of the heating medium in the first heat exchanger 21 can be improved, that is, the heating medium has absorbed a part of the heat before entering the first heat exchanger 21. In other words, the first preheating pipeline 52 realizes the cascade utilization of steam thermal energy, that is, after the steam releases heat in the first heat exchanger 21, it can still be used to preheat new heating medium, and then flow to the second heat exchange component 32, so that the steam thermal energy can be utilized to the maximum extent.

[0049] In addition, the parallel design of the first preheating pipeline 52 provides flexibility in system operation, and the flow rate and heat exchange of the heating medium in each heat exchange component can be adjusted according to actual needs.

[0050] In some embodiments, the first preheating component 5 also includes a monitoring component 71 and a control valve 72. The monitoring component 71 is arranged on the heat exchange pipeline, and the control valve 72 is arranged on the first preheating pipeline 52. The monitoring component 71 is electrically connected to the control valve 72, and the monitoring component 71 is located upstream of the control valve 72. The monitoring component 71 is used to monitor the steam temperature on the heat exchange pipeline and send a control opening and closing instruction to the control valve 72.

[0051] It is understandable that when the monitoring element 71 detects the steam temperature in the heat exchange pipeline, it sends the temperature information to the control valve 72. The control valve 72 automatically adjusts its opening and closing degree according to the received temperature information, thereby controlling the flow of steam through the first preheating pipeline 52.

[0052] That is to say, the integration of the monitoring element 71 and the control valve 72 enables the system to automatically adjust the flow of steam without manual intervention, thereby improving the automation level of the system. Through real-time monitoring and automatic adjustment, the system can accurately control the temperature and flow of steam, optimize the heat exchange process, and improve the thermal efficiency of the system.

[0053] In some embodiments, the coupled adsorbent regenerated sodium coke system of an embodiment of the present invention further includes a second preheating component 6, the hot side inlet of the second preheating component 6 is connected to the hot side outlet of the second heat exchange component 32, and at least a portion of the second preheating component 6 is placed in the preheating section 111.

[0054] It is understandable that if Figure 1 As shown, when the steam comes out of the second heat exchange component 32, it may still have a relatively high temperature. The second preheating component 6 uses this part of heat to preheat the adsorbent that is about to enter the preheating section 111 of the regeneration tower 11. Since the second preheating component 6 is partially placed in the preheating section 111, the heat source of the steam can be effectively used to preheat the adsorbent.

[0055] In some embodiments, the second preheating component 6 includes a second preheater 61 and a second preheating pipeline 62. The second preheater 61 is placed in the preheating section 111. The second preheating pipeline 62 connects the hot side outlet of the second heat exchange component 32 with the hot side inlet of the second preheating component 6.

[0056] It is understandable that after the steam comes out of the second heat exchange assembly 32 , it is transported to the second preheater 61 through the second preheating pipeline 62 , so that the heat of the steam is used again in the second preheater 61 to preheat the adsorbent that is about to enter the preheating section 111 .

[0057] The design of the second preheating assembly 6 enables thermal energy to be more fully utilized in the system, especially directly utilizing the heat of the regenerated agent in the preheating section 111, thereby improving the overall thermal efficiency. The second preheater 61 is placed in the preheating section 111, making the system design more compact, reducing space occupancy, and simplifying the system layout. By preheating the adsorbent that is about to enter the preheating section 111, the heat exchange effect of the preheating section 111 can be improved, thereby improving the performance and efficiency of the entire system.

[0058] Therefore, the coupled adsorbent regenerated sodium coke system of the present invention not only improves the thermal energy utilization efficiency but also enhances the stability and reliability of the system through the optimized design of the heating component 12, the first preheating component and the second preheating component, providing a more efficient and environmentally friendly solution for the flue gas pollutant removal and sodium coke salt production fields.

[0059] In some embodiments, the drying assembly includes a separator 33 , a dust collector 34 and an exhaust member 35 which are connected in sequence, and the separator 33 and the dust collector 34 are both connected to the silo assembly 4 so as to introduce the separated dry material into the silo assembly 4 .

[0060] It is understandable that if Figure 1 As shown, the separator 33 is connected between the drying element 31 and the silo assembly 4, and its main function is to separate the dried material and the carried gas, which helps to improve the purity of the material and prevent dust and other particles in the drying gas from entering the silo 41.

[0061] The dust collector 34 is connected to the separator 33 to capture and remove fine dust and particulate matter in the dry gas, which helps to meet environmental protection requirements while reducing the impact on subsequent equipment and the environment.

[0062] The exhaust part 35 is connected to the dust collector 34 and is used to discharge the gas after the dust removal process. The exhaust part 35 may include an exhaust pipe, a fan, etc. to ensure that the gas can be effectively discharged into the atmosphere or further processed.

[0063] In some embodiments, the silo assembly 4 includes a silo 41, a discharger 42, a packaging machine 43 and a dust removal discharger 44. The silo 41, the discharger 42 and the packaging machine 43 are connected in sequence. The silo 41 is connected to the separator 33 and the dust collector 34, and the dust removal discharger 44 is connected to the silo 41.

[0064] It is understandable that if Figure 1As shown, the silo 41 is used to store the dried material, the unloader 42 is responsible for unloading the material from the silo 41, and the packaging machine 43 is used to package the material for easy transportation and sale. Among them, the separator 33 can be a cyclone separator. That is to say, in the drying component 3, the main function of the separator 33 is to separate the dried material from the airflow. During the drying process, the material will be carried by hot air or other airflows, and the separator 33 can effectively separate the material from the airflow to facilitate the collection and storage of the material. In addition, the separator 33 can also remove dust and other solid particles in the airflow, thereby purifying the gas and reducing the pollution to subsequent dust removal equipment and the environment.

[0065] The dust removal discharger 44 is connected to the silo 41 and is used to further remove dust from the material during the unloading process, which helps to keep the silo 41 clean and reduce dust emissions.

[0066] Therefore, the coupled adsorbent regenerated sodium coke system of the present invention can more effectively process materials and gases in the drying process through the design of the separator 33, the dust collector 34 and the exhaust component 35, thereby improving the overall processing capacity and efficiency. The use of the dust collector 34 and other pollutant control equipment helps to reduce pollution to the environment and meet more stringent environmental protection standards. The integration of the unloader 42 and the packaging machine 43 in the silo assembly 4 improves the automation level of the entire system, reduces manual operations, and reduces operating costs. Through effective dust removal and emission control, the working environment is improved and the risk of workers being exposed to dust and other pollutants is reduced.
