Description

Technical Field

[0001] The present disclosure relates to the field of germanium preparation, and more particularly to a germanium dioxide hydrogen reduction exhaust gas treatment system. Background Art

[0002] Figure 1 The exhaust port 200a of the germanium dioxide reduction device 200 directly uses a long straight metal pipe 300 for exhaust.

[0003] Germanium dioxide and hydrogen undergo a reduction reaction at high temperatures to produce water: GeO2 + 2H2 → Ge + 2H2O↑. Under high-temperature conditions, the water exists as water vapor and mixes with the hydrogen before being discharged, along with some germanium dioxide dust. As the water vapor passes through the long-distance linear metal pipe 300, it cools and liquefies into water droplets, adhering to the inner wall of the long-distance linear metal pipe 300. Meanwhile, the germanium dioxide dust adheres to the water droplets as it passes through the long-distance linear metal pipe 300. Over time, muddy water accumulates within the long-distance linear metal pipe 300, eventually clogging the pipe 300. This not only affects the smooth discharge and recovery of hydrogen, but also causes hydrogen and water vapor to flow back into the germanium dioxide hydrogen reduction device 200, affecting the pressure environment within the germanium dioxide hydrogen reduction device 200 and, in turn, the germanium dioxide hydrogen reduction reaction process. Summary of the Invention

[0004] In view of the problems existing in the background technology, one purpose of the present disclosure is to provide a germanium dioxide hydrogen reduction exhaust treatment system, which can avoid the risk of muddy water accumulation caused by directly using long-distance straight metal pipes for discharge in the background technology, which will then block the long-distance straight metal pipes and affect the smooth discharge and recovery of hydrogen.

[0005] Another object of the present disclosure is to provide a germanium dioxide hydrogen reduction exhaust treatment system that can significantly recover water vapor before recovering hydrogen.

[0006] Thus, a germanium dioxide hydrogen reduction exhaust treatment system includes an air connection pipe, a collecting barrel, a connecting pipe and a water tank; one end of the air connection pipe is used to connect to the exhaust port of the germanium dioxide hydrogen reduction device; the collecting barrel has a barrel body, the barrel body is provided with a first port and a second port, the barrel body is used to be empty before the germanium dioxide hydrogen reduction exhaust treatment system starts working, the first port is for the other end of the air connection pipe to enter the barrel body; one end of the connecting pipe is connected to the second port of the collecting barrel; the water tank has a shell, a cover, a condenser and a partition, the shell is provided with a first water inlet and a second water inlet, the cover is sealed with the shell, the cover is provided with a first interface, a second interface, a third interface and a fourth interface, the partition is placed in the shell and divides the interior of the shell into a first cavity and a second cavity, the partition An overflow trough is provided at the upper part, which connects the first cavity and the second cavity. The first water inlet is provided at the bottom of the first cavity of the shell. The first cavity is used to hold water at room temperature that reaches the bottom height of the overflow trough before the germanium dioxide hydrogen reduction exhaust treatment system starts working. The second water inlet is provided at the bottom of the second cavity of the shell. The second cavity is used to be empty before the germanium dioxide hydrogen reduction exhaust treatment system starts working; the condenser is located in the first cavity and is used to be placed in the water contained in the first cavity. The two ends of the condenser are respectively connected to the first interface and the second interface for accessing the external cooling flow medium; the third interface is for the connecting pipe to penetrate and enter the first cavity for insertion into the water contained in the first cavity; the fourth interface is connected to the second cavity.

[0007] The beneficial effects of the present disclosure are as follows: in the germanium dioxide hydrogen reduction exhaust treatment system of the present disclosure, a portion of water vapor and germanium dioxide is collected by the barrel body of the collection barrel that is empty before the germanium dioxide hydrogen reduction exhaust treatment system starts working, and a portion of water vapor and germanium dioxide is collected through the second cavity of the water tank, so that the germanium dioxide and water vapor contained in the hydrogen discharged to the outside through the fourth interface of the water tank is greatly reduced (that is, the water vapor is greatly recovered before the hydrogen is recovered). Even if the fourth interface is detachably connected to a long-distance straight metal pipe like the background technology, the long-distance straight metal pipe will not have the risk of muddy water accumulation formed by germanium dioxide mixed with cooled water vapor, which will block the long-distance straight metal pipe and affect the smooth discharge and recovery of hydrogen (that is, the risk is eliminated), thereby ensuring the smooth discharge and recovery of hydrogen, and also avoiding the risk of hydrogen and water vapor backflowing and merging into the germanium dioxide hydrogen reduction device, affecting the pressure environment in the germanium dioxide hydrogen reduction device, and further affecting the reaction process of the germanium dioxide hydrogen reduction.

[0030] The accompanying drawings show embodiments of the present disclosure, and it will be understood that the disclosed embodiments are merely examples of the present disclosure, which can be implemented in various forms. Therefore, the specific details disclosed herein should not be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one of ordinary skill in the art to implement the present disclosure in various ways.

[0031] Reference Figure 2 The germanium dioxide hydrogen reduction exhaust gas treatment system 100 includes an air receiving pipe 1, a collection barrel 2, a connecting pipe 3 and a water tank 4.

[0032] One end of the air connection pipe 1 is connected to the exhaust port 200a of the germanium dioxide hydrogen reduction device 200. The collection barrel 2 comprises a barrel body 21, which is provided with a first port 211 and a second port 212. The barrel body 21 is empty before the germanium dioxide hydrogen reduction exhaust treatment system 100 begins operation. The first port 211 allows the other end of the air connection pipe 1 to enter the barrel body 21. One end of the connecting pipe 3 is connected to the second port 212 of the collection barrel 2. The water tank 4 comprises a housing 41, a cover plate 42, a condenser pipe 43, and a partition 44. The shell 41 is provided with a first water inlet 411 and a second water inlet 412, the cover plate 42 is sealed with the shell 41, and the cover plate 42 is provided with a first interface 421, a second interface 422, a third interface 423 and a fourth interface 424. The partition 44 is placed in the shell 41 and divides the interior of the shell 41 into a first cavity S1 and a second cavity S2. The partition 44 is provided with an overflow groove 441 at the upper part, and the overflow groove 441 connects the first cavity S1 and the second cavity S2. The first water inlet 411 is provided at the bottom of the first cavity S1 of the shell 41. The first cavity S1 is used to hold the germanium dioxide hydrogen reduction exhaust treatment system 100 before it starts working. 41 is at a height of 441a of the bottom surface and is water at room temperature. The second water inlet 412 is set at the bottom of the second cavity S2 of the shell 41. The second cavity S2 is used to be empty before the germanium dioxide hydrogen reduction exhaust treatment system 100 starts working; the condenser 43 is located in the first cavity S1 and is used to be placed in the water contained in the first cavity S1. The two ends of the condenser 43 are respectively connected to the first interface 421 and the second interface 422 for accessing the external cooling flow medium; the third interface 423 is for the connecting pipe 3 to penetrate and enter the first cavity S1 for insertion into the water contained in the first cavity S1; the fourth interface 424 is connected to the second cavity S2.

[0033] During operation, the water vapor, hydrogen and mixed germanium dioxide discharged from the exhaust port 200a of the germanium dioxide hydrogen reduction device 200 pass through the first port 211 of the barrel body 21 through the air connection pipe 1 and enter the barrel body 21 which is empty before the germanium dioxide hydrogen reduction exhaust treatment system 100 starts working. A part of the water vapor entering the barrel body 21 is condensed into water and collected in the barrel body 21, and at least a part of the germanium dioxide entering the collection barrel 2 is precipitated and collected in the condensed water in the barrel body 21; the hydrogen discharged from the collection barrel 2, the remaining water vapor and the remaining germanium dioxide enter the water in the first cavity S1 of the water tank 4 through the connecting pipe 3; the water contained in the first cavity S1 exchanges with the condenser 43 (that is, the cooling medium in the condenser 43). The heat is cooled, and the cooled water contained in the first cavity S1 exchanges heat with the connecting pipe 3, so that the water vapor transported in the connecting pipe 3 is cooled and condensed into water and mixed into the water in the first cavity S1. The liquid level of the water in the first cavity S1 rises and the water in the first cavity S1 overflows into the second cavity S2 through the overflow groove 441 to maintain the liquid level in the first cavity S1 does not exceed the bottom surface 441a of the overflow groove 441; the hydrogen in the water in the first cavity S1 that enters the water tank 4 through the connecting pipe 3 is cooled, overflows from the water in the first cavity S1, and is discharged to the outside through the overflow groove 441, the second cavity S2 and the fourth interface 424; the germanium dioxide in the water in the first cavity S1 that enters the water tank 4 through the connecting pipe 3 is precipitated and collected in the water in the first cavity S1.

[0034] In the germanium dioxide hydrogen reduction exhaust gas treatment system 100 disclosed in the present invention, a portion of water vapor and germanium dioxide is collected in the barrel body 21 of the collection barrel 2 which is empty before the germanium dioxide hydrogen reduction exhaust gas treatment system 100 starts working, and a portion of water vapor and germanium dioxide is collected through the second chamber S2 of the water tank 4, so that the germanium dioxide and water vapor contained in the hydrogen discharged to the outside through the fourth interface 424 of the water tank 4 is greatly reduced (that is, the water vapor is largely recovered before the hydrogen is recovered). Even if the fourth interface 424 is detachably connected to a long-distance The long-distance straight metal pipeline will not have the risk of muddy water accumulation caused by germanium dioxide mixing with the cooled water vapor, which will block the long-distance straight metal pipeline and affect the smooth discharge and recovery of hydrogen (i.e., the risk is eliminated), thereby enabling the smooth discharge and recovery of hydrogen. It also will not lead to the risk of hydrogen and water vapor flowing back and merging into the germanium dioxide hydrogen reduction device 200, affecting the pressure environment in the germanium dioxide hydrogen reduction device 200, and further affecting the reaction process of the germanium dioxide hydrogen reduction.

[0035] In the germanium dioxide hydrogen reduction exhaust treatment system 100 disclosed in the present invention, the barrel body 21 of the collecting barrel 2 is used to be in an empty state before the germanium dioxide hydrogen reduction exhaust treatment system 100 starts working, the first cavity S1 of the water tank 4 is used to hold water at room temperature that reaches the height of the bottom surface 441a of the overflow tank 441 before the germanium dioxide hydrogen reduction exhaust treatment system 100 starts working, the overflow tank 441 connects the first cavity S1 and the second cavity S2, and the second cavity S2 of the water tank 4 is used to be in an empty state before the germanium dioxide hydrogen reduction exhaust treatment system 100 starts working. Therefore, the barrel body 21 of the collecting barrel 2 and the second cavity S2 of the water tank 4 are both used to collect water vapor, hydrogen and mixed germanium dioxide discharged from the exhaust port 200a of the germanium dioxide hydrogen reduction device 200. In addition, the water vapor discharged from the fourth interface 424 is returned to the exhaust port 200a. The water vapor contained in the collected hydrogen can also be independently recovered (for example, by setting a drain valve and regularly opening and closing the drain valve to collect the water formed by this part of the water vapor). In this way, the amount of water vapor, hydrogen and germanium dioxide recovered by the barrel body 21 of the collection barrel 2, the second cavity S2 of the water tank 4 and the fourth interface 424 can be independently weighed and then compared with the theoretical water production, and the acidity and alkalinity can be detected, thereby providing feedback data for the reaction sufficiency, configuration of reactants and output of the germanium dioxide hydrogen reduction device 200 to guide the production of germanium dioxide hydrogen reduction, and also provide a reliable basis for the performance design, structural design and layout of the barrel body 21 of the collection barrel 2, the second cavity S2 of the water tank 4, the condenser 43 and the cooling medium and the external pipe 5 described later connected to the fourth interface 424.

[0036] The depth of the air receiving pipe 1 inserted into the barrel 21 is preferably such that it can be immersed in the water collected by the barrel 21 of the collection barrel 2 and converted into water by cooling the water vapor. Figure 2 As shown, the gas receiving pipe 1 is as close as possible to the bottom wall of the barrel 21 so as not to affect the discharge of water vapor, hydrogen and mixed germanium dioxide in the gas receiving pipe 1.

[0037] The internal volume of the barrel body 21 of the collection barrel 2 can be determined by the theoretical water production of the germanium dioxide hydrogen reduction device 200 during the production process, and is sufficient to accommodate water formed by cooling the water vapor and germanium dioxide.

[0038] The barrel body 21 may include a top plate portion 214 , and the first port 211 and the second port 212 are disposed on the top plate portion 214 , thereby ensuring that the second port 212 is located above the liquid level of the water collected in the barrel body 21 .

[0039] like Figure 2As shown, the bottom of the barrel 21 is provided with a first opening 213, which is used to discharge water and germanium dioxide from the barrel 21 for weighing and acidity and alkalinity testing. The first opening 213 may be provided with a control valve to control the opening and closing of the first opening 213. Figure 2 As shown, in one embodiment, the height of the end of the air receiving pipe 1 entering the barrel body 21 is the same as the height of the first opening 213 .

[0040] The material of the collecting barrel 2 is preferably corrosion-resistant material, such as polypropylene (PP) material.

[0041] Likewise, the connecting pipe 3 is preferably made of a corrosion-resistant material, such as polypropylene (PP).

[0042] like Figure 2 and Figure 4 As shown, the first water inlet 411 of the housing 41 is used to supply water to or discharge water from the first cavity S1 of the water tank 4. The first water inlet 411 may be provided with a control valve to control the opening and closing of the first water inlet 411.

[0043] The second water inlet 412 of the housing 41 is used to discharge water from the second cavity S2 of the water supply tank 4 for weighing and acidity and alkalinity testing. The second water inlet 412 may be provided with a control valve to control the opening and closing of the second water inlet 412.

[0044] like Figures 3 to 5 As shown, the housing 41 may be provided with a flange 413, and the housing 41 is sealed by the flange 413. Furthermore, the flange 413 of the housing 41 is connected to the cover plate 42 by screws 45. To improve the sealing performance, a sealing gasket (not shown) may be provided between the flange 413 of the housing 41 and the cover plate 42. The sealing gasket may be a rubber gasket.

[0045] like Figure 2 and Figure 5 As shown, the condenser tube 43 is in the form of a coil and surrounds the portion of the connecting tube 3 that extends into the first cavity S1. This improves the heat exchange efficiency between the condenser tube 43 and the connecting tube 3, increases the collection of water condensed from the water vapor discharged from the connecting tube 3 by the water in the second cavity S2, and reduces the temperature of the hydrogen discharged from the connecting tube 3. The condenser tube 43 is preferably made of a thermally conductive and corrosion-resistant material, such as brass. The cooling medium flowing within the condenser tube 43 can be cold water, for example, at a temperature below zero degrees Celsius.

[0046] For ease of installation, the two ends of the condenser pipe 43 are connected to the first interface 421 and the second interface 422 in a detachable manner, such as a pair of connectors with internal and external threads.

[0047] like Figure 5As shown, the partition plate 44 and the housing 41 are formed as a single piece, thereby simplifying the sealing and isolation between the first cavity S1 and the second cavity S2.

[0048] Likewise, the water tank 4 (shell 41 , cover 42 and partition 44 ) is preferably made of corrosion-resistant material, such as polypropylene (PP).

[0049] like Figures 2 to 5 As shown, the germanium dioxide hydrogen reduction exhaust treatment system 100 includes an external pipe 5, which is connected to the fourth interface 424. The external pipe 5 is used to connect to an external hydrogen recovery device (not shown). Similarly, the material of the external pipe 5 is preferably a corrosion-resistant material, such as polypropylene (PP). Of course, the external pipe 5 can also be a long-distance straight metal pipe as described in the background art. A drain valve can be provided at the end of the external pipe 5 to collect water.
