[0037] This utility model proposes a regenerated gas drying device.
[0038] Please see Figure 1 In one embodiment of this utility model, the regenerated gas drying device includes a first material cylinder 10, a recycling station 20, a first pipeline 31, a second pipeline 32, and a third pipeline 33. The first material cylinder 10 is provided with a through hole 11; the recycling station 20 is provided with a reuse port and an air outlet 22; one end of the first pipeline 31 is connected to the through hole 11, and the other end is provided with a first one-way valve 81; one end of the second pipeline 32 is connected to the first one-way valve 81, and the other end is connected to the reuse port, wherein the airflow direction of the first one-way valve 81 is set towards the second pipeline 32; one end of the third pipeline 33 is connected to the air outlet 22, and the other end is connected to the first pipeline 31, wherein the third pipeline 33 is provided with a second one-way valve 82, and the airflow direction of the second one-way valve 82 is set towards the first pipeline 31.
[0039] The recycling station 20 is connected to the exhaust port of the heat source equipment in the upstream process to collect the high-heat gas generated by the external heat source equipment during production. The high-heat gas from the external heat source equipment is transferred to the recycling station 20 for storage through the third pipeline 33. The recycling station 20 uses the recovered high-heat gas to dry the material in the first feed cylinder 10.
[0040] To ensure drying effectiveness, the recovered high-heat gas can be further processed at the recycling station 20. For example, in this embodiment, the recycling station 20 uses a hydrogen station, and the recovered high-heat gas is repressurized and heated to form dry gas. Even with reprocessing, the gas discharged from the external heat source equipment still retains residual heat, thus reducing the energy consumption for repressurization and heating, indirectly reducing product production costs. At the same time, it can also improve the pressurization and heating efficiency of the dry gas and reduce the power consumption during the pressurization and heating process.
[0041] The second pipe 32 is used to connect the recycling station 20 and the first material cylinder 10, forming an air passage between them. The dry gas in the recycling station 20 enters the first material cylinder 10 through the air outlet 22, the first pipe 31, and the through hole 11.
[0042] Furthermore, in this embodiment, the through hole 11 is located at the top of the first material cylinder 10. After the high-temperature and high-pressure drying gas is introduced into the first material cylinder 10, it dries the material inside the first material cylinder 10. The dried exhaust gas retains residual heat, so the exhaust gas flows upward and is conveniently discharged from the through hole 11 at the top.
[0043] Exhaust gas is discharged from through-hole 11 into first pipe 31, and then discharged along first pipe 31 into exhaust gas treatment port 92. This embodiment also includes an exhaust gas processor connected to the exhaust gas treatment port 92. The exhaust gas is treated by the exhaust gas processor to prevent environmental pollution.
[0044] In other words, in this embodiment, the filling of the first material cylinder 10 with dry gas or the discharge of waste gas are both carried out through the through hole 11.
[0045] Therefore, in this embodiment, a first check valve 81 is provided on the first pipeline 31 and a second check valve 82 is provided on the second pipeline 32. The flow direction of the airflow in the pipeline is controlled by adjusting the first check valve 81 and the second check valve 82.
[0046] Specifically, during drying, the first one-way valve 81 is closed and the second one-way valve 82 is opened. The high-temperature, high-pressure drying gas is transmitted from the air outlet 22 to the first material cylinder 10 along the second pipeline 32 to dry the material inside the first material cylinder 10. After drying is completed, the first one-way valve 81 is opened and the second one-way valve 82 is closed, and the gas flows through the second pipeline 32 to the exhaust gas treatment port 92.
[0047] The technical solution of this utility model adopts the first pipeline 31, the second pipeline 32 and the third pipeline 33 to form a loop. The gas with residual heat discharged from the external heat source is recovered through the recycling station 20, and the recovered dry gas is reused in the next drying process, thereby improving the utilization rate of the dry gas, reducing the power consumption generated by heating the dry gas, and thus reducing the overall production cost of the equipment.
[0048] In another embodiment, the regenerated gas drying device further includes: a heating element 40 and a fourth pipeline 34, wherein the heating element 40 is provided with a hot air outlet 41; one end of the fourth pipeline 34 is connected to the hot air outlet 41 and the other end is connected to the second pipeline 32, wherein the fourth pipeline 34 is connected to the pipeline portion of the second pipeline 32 located between the air outlet 22 and the second one-way valve 82.
[0049] To ensure stable equipment production, when production demand is high, the recycling station 20 cannot meet the supply requirements of drying gas. Therefore, in this embodiment, a heating element 40 is additionally provided to pressurize and heat the gas.
[0050] The drying gas processed by the heating element 40 flows into the first material cylinder 10 through the loop formed by the hot air inlet 41, the fourth pipe 34, and the second pipe 32, thereby drying the material in the first material cylinder 10.
[0051] It should be noted that during the process of using the heating element 40 to transfer the drying gas into the first material cylinder 10, the first one-way valve 81 is kept closed and the second one-way valve 82 is kept open, thereby preventing the drying gas from flowing from the first one-way valve 81 into the exhaust gas treatment port 92.
[0052] In another embodiment, the regenerated gas drying device further includes a second material cylinder 50 and a fifth pipeline 35, wherein the first material cylinder 10 and the second material cylinder 50 are disposed opposite to each other; one end of the fifth pipeline 35 is connected to the fourth pipeline 34 and the other end is connected to the second material cylinder 50, and a third one-way valve 83 is provided on the fifth pipeline 35, wherein the airflow direction of the third one-way valve 83 is disposed toward one side of the second material cylinder 50.
[0053] In this embodiment, the first material cylinder 10 and the second material cylinder 50 adopt similar structures, and the fifth pipe 35 and the fourth pipe 34 are connected to ensure that the drying gas in the heating element 40 can be transmitted to the second material cylinder 50 through the fourth pipe 34 and the fifth pipe 35 at the same time to dry the material in the second material cylinder 50.
[0054] When drying the material in the second material cylinder 50, the third check valve 83 is kept open so that the drying gas can be transmitted to the second material cylinder 50 along the fourth pipeline 34 and the fifth pipeline 35.
[0055] When only the material in the first cylinder 10 or the second cylinder 50 needs to be dried, only the corresponding one-way valve needs to be opened. For example, opening the first one-way valve 81 alone will only dry the material in the first cylinder 10; opening the third one-way valve 83 alone will only dry the material in the second cylinder 50. When it is necessary to dry the material in both the first cylinder 10 and the second cylinder 50 simultaneously, both the first one-way valve 81 and the third one-way valve 83 should be opened at the same time.
[0056] In another embodiment, the regenerated gas drying device further includes a sixth pipeline 36, one end of which is connected to the exhaust gas treatment port 92 and the other end is connected to the second material cylinder 50. A fourth one-way valve 84 is provided on the sixth pipeline 36, and the airflow direction of the fourth one-way valve 84 is set towards the exhaust gas treatment port 92.
[0057] It is understandable that, since the structure of the second material cylinder 50 is similar to that of the first material cylinder 10, and a through hole 11 is also provided at the top, the sixth pipe 36 is connected to the exhaust gas treatment port 92. The dried exhaust gas in the second material cylinder 50 is discharged through the through hole 11, and the discharged exhaust gas is discharged through the through hole 11, the sixth pipe 36, and the exhaust gas treatment port 92.
[0058] It should be noted that after the material in the second material cylinder 50 is dried, when the waste gas is recovered, the third one-way valve 83 must be kept closed, and the fourth one-way valve 84 on the sixth pipeline 36 must be opened at the same time, so that the waste gas can be discharged from the sixth pipeline 36 to the tail gas treatment port 92.
[0059] In another embodiment, the regenerated gas drying device further includes a support 60, the two ends of which are connected to the side walls of the first material cylinder 10 and the second material cylinder 50, respectively, and the heating element 40 is disposed on the support 60.
[0060] To avoid interference between the first material cylinder 10 and the second material cylinder 50, the first material cylinder 10 and the second material cylinder 50 are spaced apart. In this embodiment, a bracket 60 is provided on the outer wall of the first material cylinder 10 and the second material cylinder 50 for mounting the heating element 40. This reduces the footprint of the equipment and improves the space utilization rate of the equipment.
[0061] Meanwhile, the bottom of the first material cylinder 10 and the second material cylinder 50 are also provided with a discharge port 12. The dried material can be discharged from the discharge port 12 at the bottom and recycled to the collection equipment through the discharge pipe 91.
[0062] The discharge pipe 91 can be a three-way pipe, with its two ends connected to the discharge ports 12 of the first material cylinder 10 and the second material cylinder 50 respectively, and the other end connected to the external material collection equipment.
[0063] A one-way valve can also be installed on the discharge pipe 91 to keep the one-way valve on the discharge pipe 91 closed during drying, thereby ensuring the sealing of the first material cylinder 10 and the second material cylinder 50 and preventing the leakage of high temperature and high pressure drying gas.
[0064] In another embodiment, the regenerated gas drying device further includes a base 71 and a support frame 72, the support frame 72 being disposed on the base 71, and the first material cylinder 10 being disposed on the support frame 72.
[0065] The support frame 72 includes a connecting part 721 and a plurality of clamping parts 722. The connecting part 721 is disposed on the base 71. The plurality of clamping parts 722 are spaced apart on the connecting part 721. The clamping parts 722 are used to clamp the first material cylinder 10.
[0066] Please see Figure 1 In this embodiment, both the first material cylinder 10 and the second material cylinder 50 adopt a cylindrical structure. Therefore, the clamping part 722 can be an annular patch, which wraps around the outer wall of the first material cylinder 10 and the second material cylinder 50 and is fixed and limited by studs to clamp the first material cylinder 10 and the second material cylinder 50.
[0067] In this embodiment, two sets of clamping parts 722 are provided on the same material cylinder, located at the top and bottom of the material cylinder respectively, to keep the material cylinder stable vertically.
[0068] Both support frames 72 are mounted on the base 71. The upper surface of the base 71 is a flat surface. The two support frames 72 have similar structures, thus ensuring that the height of the first material cylinder 10 and the second material cylinder 50 is consistent after installation, so that the first material cylinder 10 and the second material cylinder 50 are symmetrically arranged after the various pipelines are connected.
[0069] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
