Description

Technical Field

[0001] The invention relates to the field of hydrogen chloride generators, in particular to a hydrogen chloride gas generator based on concentrated sulfuric acid. Background Art

[0002] The existing hydrogen chloride generator is heated and prepared by sodium chloride and concentrated sulfuric acid in the laboratory. After the hydrogen chloride is prepared by this method, sodium sulfate crystals will be precipitated at the bottom of the flask. Therefore, after the hydrogen chloride is collected, the bottom of the flask needs to be cleaned. The cleaning efficiency of the sodium sulfate at the bottom of the flask is low, and the cleaning effect of the sodium sulfate is not ideal. In the process of preparing hydrogen chloride gas, concentrated sulfuric acid and sodium chloride need to be continuously heated, so that the temperature inside the flask continues to rise. The temperature inside the flask cannot continue to rise, and then the flask needs to be cooled. Cooling the flask with cooling water is a relatively simple cooling method, but the cooling water needs to be replaced after a period of use because the temperature of the cooling water continues to rise and the condensation effect of the condensed water is not ideal.

[0005] Preferably, the cooling mechanism includes a rotating rod rotatably connected to the bottom of the cooling tank. A plurality of stirring blades in a spiral structure are arranged on the rotating rod. A first runner is arranged at the top of the rotating rod. A crank is arranged on the upper surface of the first runner. The stirring blades are located inside the cooling tank. A cooling pipe matched with the stirring blades is arranged on the side wall of the cooling tank. By arranging the crank, it is convenient to rotate manually. Thus, the crank will drive the rotating rod to rotate. After the rotating rod rotates, it drives the first runner to rotate. When the rotating rod rotates, it drives the stirring blades fixed on its surface to rotate. When the stirring blades rotate, they will drive the water inside the cooling tank to be cooled. When the stirring blades rotate, they can send the water from the cooling tank into the inside of the cooling pipe. The water inside the cooling pipe will enter the cooling tank from the top of the cooling tank, thus realizing cooling.

[0006] Preferably, the condensation mechanism includes a condensation pipe installed on the cooling tank. One end of the condensation pipe is connected with an inlet pipe. The end of the inlet pipe is connected with the mixing mechanism. The end of the condensation pipe communicates with an exhaust pipe. Through the arranged condensation pipe, the hydrogen chloride gas entering from the inside of the inlet pipe can be cooled by water. Thus, hydrogen chloride will condense inside the condensation pipe. Thus, it realizes that the hydrogen chloride inside the condensation pipe condenses from gas to form a liquid and stays inside the condensation pipe. And some uncooled tail gas is discharged from the exhaust pipe and collected. When the hydrogen chloride inside the condensation pipe accumulates to an appropriate amount, the hydrogen chloride can be collected from the inside of the condensation pipe.

[0007] Preferably, the transmission mechanism includes a second runner meshed with the first runner. A roller is arranged at the bottom of the second runner. A bearing is arranged on the surface of the roller. The bottom of the bearing is fixed on the top of a support pipe. A first helical gear is fixed at the bottom of the roller. The roller penetrates through the inside of the support pipe and is connected with the stirring mechanism. When the first runner rotates, the first runner can drive the second runner to rotate. When the second runner rotates, the second runner can drive the roller to rotate synchronously. Thus, when the roller rotates, it drives the first helical gear fixed at its bottom to rotate. The rotation of the first helical gear will drive the second helical gear on the stirring mechanism to rotate.

[0008] Preferably, the stirring mechanism includes a second helical gear matched with the first helical gear. The second helical gear is fixed on a guide rod. Guide plates are arranged on the surface of the guide rod.

[0009] Preferably, the stirring mechanism further includes a guiding tube arranged on the mixing mechanism. A plug cover is installed inside the guiding tube. The plug cover and the guiding tube are in threaded connection. A screwing cover is fixed to the end of the plug cover. A sealing gasket that is sealed with the guiding tube is arranged on the side wall of the screwing cover. Driven by the first bevel gear, the second bevel gear drives the guiding rod to rotate. When the guiding rod rotates, it drives the guiding plate to rotate. At this time, the guiding plate will push the concentrated sulfuric acid inside the mixing tank to be stirred. Since the plug cover is connected inside the guiding tube, the concentrated sulfuric acid and aluminum chloride inside the cooling tank are fully mixed. While mixing, it can drive the concentrated sulfuric acid to be heated by the combustion mechanism. When the concentrated sulfuric acid and sodium chloride are heated, molten sodium sulfate is formed. Open the plug cover. At this time, when the guiding plate rotates, the guiding plate will drive the sodium sulfate to move inside the guiding tube. Thus, the sodium sulfate inside the guiding tube will enter the inside of the collection mechanism, facilitating the collection of sodium sulfate.

[0010] Preferably, the mixing mechanism includes a mixing tank located on one side of the cooling tank. A feed port is arranged on the side wall of the mixing tank. A top plug is installed inside the feed port. An addition port is arranged on the top of the mixing tank. The feed port facilitates the addition of sodium chloride, and the addition port facilitates the addition of concentrated sulfuric acid.

[0011] Preferably, the combustion mechanism includes a burner installed at the bottom of the mixing tank. An air inlet hole is arranged inside the burner. The top of the air inlet hole communicates with a combustion chamber. By burning the burner, the mixing tank is heated, so that the concentrated sulfuric acid inside the mixing tank is heated.

[0012] Preferably, the collection mechanism includes a collection shell installed on the base. A plug rod is arranged on the side wall of the collection shell. A plug block is fixed to the end of the plug rod. The plug block abuts against the guiding block.

[0013] Preferably, the collection mechanism further includes a pull rod fixed below the guiding block. A pull plate is fixed to the bottom of the pull rod. A spring is arranged at the bottom of the guiding block. The spring is arranged inside the inner cavity. The inner cavity is opened inside the base. A guiding groove that cooperates with the guiding block is arranged inside the base.

[0014] Preferably, the collection mechanism further includes a rope groove formed inside the base. A pull rope is installed inside the rope groove. One end of the pull rope is fixed to the side wall of a pull rod, and the other end of the pull rope is fixed to the end of another pull rod. By fixing the inserted rod on the side wall of the collection shell, the inserted rod drives the insertion block to move synchronously. When the insertion block is abutted by the guide block, the guide block limits the insertion block, and the insertion block enables the inserted rod to support the collection shell, so as to collect the molten sodium sulfate inside the collection shell; by providing the pull plate, it is convenient to pull. When the pull plate is pulled, the pull plate drives the pull rod, so the pull rod moves downward. When the pull rod moves downward, the pull rod drives the guide block to move downward. When the pull rod moves downward, the pull rod drives the pull rope to move. At the same time, the pull rope synchronously drives another pull rod to move downward. When the pull rod moves downward, the pull rod drives the guide block at the top to move downward, so that the guide block is separated from the insertion block. After the insertion block is separated from the guide block, the collection shell is removed from the base.

[0027] Specifically, the cooling mechanism 1 includes a rotating rod 13 rotatably connected to the bottom of the cooling tank 2, a plurality of stirring blades 14 in a spiral structure are arranged on the rotating rod 13, a first runner 12 is arranged at the top of the rotating rod 13, a rocking handle 11 is arranged on the upper surface of the first runner 12, the stirring blades 14 are located inside the cooling tank 2, and a cooling pipe 15 matching the stirring blades 14 is arranged on the side wall of the cooling tank 2, and the bottom of the cooling pipe 15 is communicated with the inside of the cooling tank 2. By providing the rocking handle 11, it is convenient to rotate manually, so the rocking handle 11 will drive the rotating rod 13 to rotate, the rotating rod 13 will drive the first runner 12 to rotate after rotation, when the rotating rod 13 rotates, it will drive the stirring blades 14 fixed on its surface to rotate, when the stirring blades 14 rotate, they will drive the water inside the cooling tank 2 to be cooled. Since the stirring blades 14 are in a spiral structure, the rotation of the stirring blades 14 will convey the water inside the cooling tank 2 upward, forming a greater pressure at the top of the cooling tank 2, and the water flow will enter the inside of the cooling pipe 15 from the top of the cooling tank 2, and while realizing the cooling of the cooling water, a cycle is formed; the rotation of the stirring blades 14 will convey the water upward from the water inside the cooling tank 2, and when the stirring blades 14 rotate, they can send the water from the cooling tank 2 into the inside of the cooling pipe 15, and the water inside the cooling pipe 15 will enter the cooling tank 2 from the top of the cooling tank 2, thus realizing cooling.

[0028] Specifically, the condensation mechanism 3 includes a condensation pipe 31 installed on the cooling tank 2. One end of the condensation pipe 31 is connected to an intake pipe 32, the end of the intake pipe 32 is connected to the mixing mechanism 7, and the end of the condensation pipe 31 is communicated with an exhaust pipe 33. The provided condensation pipe 31 can cool the hydrogen chloride gas entering from the inside of the intake pipe 32 with water, so that the hydrogen chloride will condense inside the condensation pipe 31, thereby realizing that the hydrogen chloride inside the condensation pipe 31 condenses from gas to form a liquid and remains inside the condensation pipe 31, while some uncooled tail gas is discharged from the exhaust pipe 33 and collected. When the hydrogen chloride inside the condensation pipe 31 accumulates to an appropriate amount, the hydrogen chloride can be collected from the inside of the condensation pipe 31. Refer to the attached instructions Figure 2 , when the hydrogen chloride condensed in the exhaust pipe 33 forms a liquid, the liquid enters the inside of the condensation pipe 31 from the exhaust pipe 33.

A small amount of hydrogen chloride in the tail gas is collected and then pressurized and condensed finally, avoiding the pollution caused by discharging the tail gas into the air.

[0029] Specifically, the transmission mechanism 5 includes a second runner 53 meshed with the first runner 12. A roller 55 is arranged at the bottom of the second runner 53. A bearing 54 is arranged on the surface of the roller 55. The bottom of the bearing 54 is fixed on the top of a support pipe 51. A first helical gear 52 is fixed at the bottom of the roller 55. The roller 55 penetrates through the inside of the support pipe 51 and is connected to the stirring mechanism 8. When the first runner 12 rotates, the first runner 12 can drive the second runner 53 to rotate. When the second runner 53 rotates, the second runner 53 can drive the roller 55 to rotate synchronously. Thus, when the roller 55 rotates, it drives the first helical gear 52 fixed at its bottom to rotate. The rotation of the first helical gear 52 will drive the second helical gear 82 on the stirring mechanism 8 to rotate.

[0030] Specifically, the stirring mechanism 8 includes a second helical gear 82 cooperating with the first helical gear 52. The second helical gear 82 is fixed on a guide rod 81. Guide plates 83 are arranged on the surface of the guide rod 81.

[0031] Specifically, the stirring mechanism 8 further includes a guide pipe 84 provided on the mixing mechanism 7. A plug cover 85 is installed inside the guide pipe 84. The plug cover 85 is threadedly connected to the guide pipe 84. A turning cover 87 is fixed to the end of the plug cover 85. A sealing gasket 86 that is sealed with the guide pipe 84 is provided on the side wall of the turning cover 87. The second bevel gear 82 is driven by the first bevel gear 52, so that the second bevel gear 82 drives the guide rod 81 to rotate. When the guide rod 81 rotates, it drives the guide plate 83 to rotate. At this time, the guide plate 83 will push the concentrated sulfuric acid inside the mixing tank 71 for stirring. Since the plug cover 85 is connected inside the guide pipe 84, the concentrated sulfuric acid and aluminum chloride inside the cooling tank 2 are fully mixed. While mixing, the concentrated sulfuric acid can be driven to be heated by the combustion mechanism 6. When the concentrated sulfuric acid and sodium chloride are heated, molten sodium sulfate is formed. Open the plug cover 85. At this time, when the guide plate 83 rotates, the guide plate 83 rotates to push the sodium sulfate to move. Furthermore, the guide plate 83 will drive the sodium sulfate to move inside the guide pipe 84. Thus, the sodium sulfate inside the guide pipe 84 will enter the collection mechanism 9, which is convenient for collecting the sodium sulfate.

[0032] Specifically, the mixing mechanism 7 includes a mixing tank 71 located on one side of the cooling tank 2. A guide pipe 84 is fixedly connected to the side wall of the mixing tank. A feed port 72 is provided on the side wall of the mixing tank 71. A top plug 73 is installed inside the feed port 72. An addition port 74 is provided at the top of the mixing tank 71. The feed port 72 facilitates the addition of sodium chloride, and the addition port 74 facilitates the addition of concentrated sulfuric acid.

[0033] Specifically, the combustion mechanism 6 includes a burner 61 installed at the bottom of the mixing tank 71. An air inlet hole 63 is provided inside the burner 61. The top of the air inlet hole 63 communicates with a combustion chamber 62. By burning the burner 61, the mixing tank 71 is heated, so that the concentrated sulfuric acid inside the mixing tank 71 is heated.

[0034] Specifically, the collection mechanism 9 includes a collection shell 91 installed on the base 4. A plug rod 910 is provided on the side wall of the collection shell 91. A plug block 911 is fixed to the end of the plug rod 910. The plug block 911 abuts against the guide block 96.

[0035] Specifically, the collection mechanism 9 further includes a pull rod 93 fixed below the guide block 96. A pull plate 92 is fixed to the bottom of the pull rod 93. A spring 94 is provided at the bottom of the guide block 96. The spring 94 is arranged inside the inner cavity 95. The inner cavity 95 is opened inside the base 4. A guide groove 97 that cooperates with the guide block 96 is provided inside the base 4.

[0036] Specifically, the collecting mechanism 9 further includes a rope groove 99 opened inside the base 4. A pull rope 98 is installed inside the rope groove 99. One end of the pull rope 98 is fixed to the side wall of a pull rod 93, and the other end of the pull rope 98 is fixed to the end of another pull rod 93. The insertion rod 910 is fixed to the side wall of the collecting shell 91, so that the insertion rod 910 drives the insertion block 911 to move synchronously. When the insertion block 911 is abutted by the guide block 96, the guide block 96 limits the insertion block 911. The insertion block 911 enables the insertion rod 910 to support the collecting shell 91, so as to collect the molten sodium sulfate inside the collecting shell 91. By providing the pull plate 92, it is convenient to pull. When the pull plate 92 is pulled, the pull plate 92 will drive the pull rod 93, so that the pull rod 93 moves downward. When the pull rod 93 moves downward, the pull rod 93 drives the guide block 96 to move downward. When the pull rod 93 moves downward, the pull rod 93 drives the pull rope 98 to move. At the same time, the pull rope 98 synchronously drives another pull rod 93 to move downward. When the pull rod 93 moves downward, the pull rod 93 drives the guide block 96 at the top to move downward, so that the guide block 96 is separated from the insertion block 911. After the insertion block 911 is separated from the guide block 96, the collecting shell 91 is detached from the base 4.

[0037] When the present invention is in use, sodium chloride is added from the feed port 72, and concentrated sulfuric acid is added from the addition port 74. The burner 61 is turned on so that the burner 61 heats the mixing tank 71. At this time, the crank 11 is rotated, and thus the crank 11 drives the rotating rod 13 to rotate. After the rotating rod 13 rotates, it drives the first runner 12 to rotate. When the rotating rod 13 rotates, it drives the stirring blades 14 fixed on its surface to rotate. When the stirring blades 14 rotate, they drive the water inside the cooling tank 2 to be cooled. When the stirring blades 14 rotate, they can send the water from the cooling tank 2 into the inside of the cooling pipe 15, and the water inside the cooling pipe 15 enters the cooling tank 2 from the top of the cooling tank 2, thus realizing cooling. At the same time, when the first runner 12 rotates, the first runner 12 can drive the second runner 53 to rotate. When the second runner 53 rotates, the second runner 53 can drive the roller 55 to rotate synchronously. Thus, when the roller 55 rotates, it drives the first bevel gear 52 fixed at its bottom to rotate. The rotation of the first bevel gear 52 drives the second bevel gear 82 on the stirring mechanism 8 to rotate. At this time, the second bevel gear 82 is driven by the first bevel gear 52, so the second bevel gear 82 drives the guide rod 81 to rotate. When the guide rod 81 rotates, it drives the guide plate 83 to rotate. At this time, the guide plate 83 pushes the concentrated sulfuric acid inside the mixing tank 71 to be stirred. Since the plug cover 85 is connected inside the guide pipe 84, the concentrated sulfuric acid and aluminum chloride inside the cooling tank 2 are fully mixed. During the mixing, the concentrated sulfuric acid can be heated by the combustion mechanism 6. When the concentrated sulfuric acid and sodium chloride are heated to completion, molten sodium sulfate is formed. The plug cover 85 is opened. At this time, when the guide plate 83 rotates, the guide plate 83 drives the sodium sulfate to move inside the guide pipe 84. Thus, the sodium sulfate inside the guide pipe 84 enters the inside of the collection mechanism 9. Since the insertion rod 910 is fixed on the side wall of the collection shell 91, the insertion rod 910 drives the insertion block 911 to move synchronously. When the insertion block 911 is abutted by the guide block 96, the guide block 96 limits the insertion block 911. The insertion block 911 enables the insertion rod 910 to support the collection shell 91, so that the molten sodium sulfate inside the collection shell 91 is collected. By providing the pull plate 92, it is convenient to pull. When the pull plate 92 is pulled, the pull plate 92 drives the pull rod 93. Thus, the pull rod 93 moves downward. When the pull rod 93 moves downward, the pull rod 93 drives the guide block 96 to move downward. When the pull rod 93 moves downward, the pull rod 93 drives the pull rope 98 to move. At the same time, the pull rope 98 synchronously drives another pull rod 93 to move downward. When the pull rod 93 moves downward, the pull rod 93 drives the upper guide block 96 to move downward, so that the guide block 96 is separated from the insertion block 911. After the insertion block 911 is separated from the guide block 96, the collection shell 91 is detached from the base 4. Thus, it is convenient to collect the sodium sulfate.

A guiding groove (97) matched with the guiding block (96) is arranged inside the base (4). The collection mechanism (9) further includes a rope groove (99) opened inside the base (4). A pull rope (98) is installed inside the rope groove (99). One end of the pull rope (98) is fixed on the side wall of a pull rod (93). The other end of the pull rope (98) is fixed at the end of a pull rod (93). During use, sodium chloride is added from the feed port (72), and concentrated sulfuric acid is added from the addition port (74). The burner (61) is turned on so that the burner (61) heats the mixing tank (71). At this time, the crank (11) is rotated, so that the crank (11) drives the rotating rod (13) to rotate. After the rotating rod (13) rotates, it drives the first runner (12) to rotate. When the rotating rod (13) rotates, it drives the stirring blades (14) fixed on its surface to rotate. When the stirring blades (14) rotate, they drive the water inside the cooling tank (2) to be cooled. When the stirring blades (14) rotate, they can send the water from the cooling tank (2) into the inside of the cooling pipe (15). The water inside the cooling pipe (15) enters the inside of the cooling tank (2) from the bottom of the cooling tank (2), thus realizing cooling. At the same time, the rotation of the first runner (12) can drive the second runner (53) to rotate, and the rotation of the second runner (53) can drive the roller (55) to rotate synchronously, thereby driving the first bevel gear (52) fixed at the bottom of the roller (55) to rotate. The rotation of the first bevel gear (52) drives the second bevel gear (82) on the stirring mechanism (8) to rotate. At this time, the second bevel gear (82) is driven by the first bevel gear (52), so that the second bevel gear (82) drives the guide rod (81) to rotate. When the guide rod (81) rotates, it drives the guide plate (83) to rotate. At this time, the guide plate (83) pushes the concentrated sulfuric acid inside the mixing tank (71) to be stirred. Since the plug cover (85) is connected inside the guide pipe (84), the concentrated sulfuric acid and sodium chloride inside the mixing tank (71) are fully mixed. During the mixing, the concentrated sulfuric acid can be heated by the combustion mechanism (6). When the reaction between concentrated sulfuric acid and sodium chloride is completed, molten sodium sulfate is formed. The plug cover (85) is opened. At this time, when the guide plate (83) rotates, the guide plate (83) drives the sodium sulfate to move inside the guide pipe (84). Thus, the sodium sulfate inside the guide pipe (84) enters the inside of the collection mechanism (9). Since the insertion rod (910) is fixed on the side wall of the collection shell (91), the insertion rod (910) drives the insertion block (911) to move synchronously. When the insertion block (911) is abutted by the guide block (96), the guide block (96) limits the insertion block (911). The insertion block (911) makes the insertion rod (910) support the collection shell (91), so as to collect the molten sodium sulfate inside the collection shell (91).Through the provided pull plate (92), it is convenient to pull. When the pull plate (92) is pulled, the pull plate (92) will drive the pull rod (93), so that the pull rod (93) moves downward. When the pull rod (93) moves downward, the pull rod (93) drives the guide block (96) to move downward. When the pull rod (93) moves downward, the pull rod (93) drives the pull rope (98) to move. At the same time, the pull rope (98) synchronously drives another pull rod (93) to move downward. When the pull rod (93) moves downward, the pull rod (93) drives the guide block (96) at the top to move downward, so that the guide block (96) disengages from the insertion block (911). After the insertion block (911) disengages from the guide block (96), the collection shell (91) is removed from the base (4); thus, it is convenient to collect sodium sulfate.
