Technical Field
[0001] The invention relates to the field of ultra-high purity arsenic distillation and purification, in particular to a distillation device for arsenic purification and a distillation method thereof. Background Art
[0002] Distillation is mainly used to separate and purify various chemicals, fuels and drugs. For example, in the petroleum industry, petroleum distillation is used to separate crude oil into different fractions, such as gasoline, diesel, kerosene, etc. In the pharmaceutical industry, distillation is used to purify impurities in chemicals to ensure the purity of the substance.
[0003] The existing device separates the mixture by placing the items to be distilled in the distillation device, heating the mixture to partially vaporize it, and then using condensation technology to partially condense the gas phase. During the distillation process, the vaporized gas moves upward and is condensed and collected at the top of the tower.
[0004] High-purity arsenic refers to metallic arsenic with a total amount of impurities less than 10ppm. It is silver-grey with a metallic luster. When exposed to air, the surface gradually oxidizes and turns black. It is mainly used to prepare GaAs, InAs, and other III-V compound semiconductor materials and silicon and germanium single crystal dopants. It is also used to prepare As 2 Se 3 (infrared transmission glass, laser printer, etc.), As 2 S 3 (infrared-transmitting glass), etc. The mist generated during the purification and distillation of ultra-high-purity arsenic cannot come into good contact with the top plate, causing part of the distilled mist liquid to fall back into the distilling liquid, affecting the purity of the product and requiring multiple distillations. The original device was connected by bolts and threaded rings, but the bolts and threaded rings would expand and contract during multiple heating and cooling, causing problems with the sealing of the bolts and threaded rings. Summary of the invention
[0005] The purpose of the present invention is to provide a distillation device for arsenic purification and a distillation method thereof in order to solve the problem that the mist generated during the purification and distillation of ultra-high purity arsenic cannot come into good contact with the top plate, resulting in that part of the mist liquid after distillation will fall into the liquid being distilled again, requiring multiple distillations.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a distillation device for arsenic purification and a distillation method thereof, wherein an article to be distilled is placed in a main body of the distillation device through a feed port, and the article in the main body is heated by heating a heating ring to gasify the liquid into steam, and the steam floats toward the top of the main body. When the steam floats upward and contacts the inclined plate, the inclined plate itself will be driven to heat up by the temperature inside the main body, and the steam will not form liquid. The steam will float upward again into the interior of the fourth tank, contact the surface of the inclined heat conduction plate, and drive the liquid in the refrigeration pipe to circulate through a circulating refrigeration pump to cool the inclined heat conduction plate.

When the droplets are squeezed by the inclined plate, they will be adsorbed inside the No. 4 slot in the inclined plate. Because the inner wall of the No. 4 slot is provided with a groove, the droplets adsorbed inside the No. 4 slot are intercepted by the groove to prevent the liquid generated by the mist from falling into the liquid being distilled again.

When the liquid circulates, it enters the cylinder and drives the fan to rotate. The fan drives the No. 2 rotating shaft to rotate, and the No. 2 rotating shaft drives the inclined heat conductive plate to rotate. When the inclined heat conductive plate is cooled, the steam contacted by the inclined heat conductive plate condenses into droplets after being cooled. A cylinder is arranged in the middle of the top of the wedge-shaped plate, and the inside of the cylinder is rotatably connected with a fan.

[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. By setting the inclined plate itself, the temperature inside the main body will be driven to rise, and the steam will not form liquid. The steam will float upward again and enter the interior of the No. 4 slot, contact the surface of the inclined heat transfer plate, and drive the liquid in the refrigeration pipe to circulate through the circulating refrigeration pump to cool the inclined heat transfer plate. When the liquid circulates, it enters the cylinder to push the fan to rotate, and the fan drives the inclined heat transfer plate to rotate. When the inclined heat transfer plate is cooled, the inclined heat transfer plate drives the droplets to contact the top of the inclined plate 6, so that the droplets in the inclined heat transfer plate are scraped by the top of the inclined plate.

[0018] 2. Through the setting of the heat insulation ring plate, when the inclined plate itself is driven by the temperature inside the main body to heat up and the inclined heat conduction plate is cooled, the heat insulation ring plate effectively isolates and prevents the temperature of the inclined heat conduction plate from affecting the temperature of the inclined plate. When the circulating refrigeration pump is in motion, the circulating refrigeration pump itself will generate a certain vibration. The vibration of the circulating refrigeration pump drives the inclined heat conduction plate at the bottom of the top plate to vibrate, making it easier for droplets to be discharged from the water outlet.
[0019] 3. The annular block plate is driven to move inside the No. 1 annular groove by the set rotating ring.

Through the provided heat insulating ring plate 507, when the inclined plate 6 itself is driven to heat up by the temperature inside the main body 101 and cool down by the inclined heat conducting plate 506, the heat insulating ring plate 507 is effectively isolated to prevent the temperature of the inclined heat conducting plate 506 from affecting the temperature of the inclined plate 6. When the steam floats upward and contacts the inclined plate 6 , the inclined plate 6 itself will be heated up by the temperature inside the main body 101 , and the steam will not form liquid. The steam will float upward again and enter the interior of the fourth tank 601 .
[0029] The top of the inclined heat conducting plate 506 is rotatably connected to a second rotating shaft 505, which contacts the surface of the inclined heat conducting plate 506. A cylinder 503 is provided in the middle of the top of the wedge-shaped plate 501, and a fan 504 is rotatably connected inside the cylinder 503. The top of the second rotating shaft 505 passes through the wedge-shaped plate 501, and the cylinder 503 is fixedly connected to the bottom of the fan 504. A refrigeration pipe 502 is provided in the wedge plate 501, and a handle 401 is provided on the top of the top plate 4. A circulating refrigeration pump 5 is installed on the top of the top plate 4 at one end of the handle 401, and the circulating refrigeration pump 5 is connected to the refrigeration pipe 502. The circulating refrigeration pump 5 drives the liquid in the refrigeration tube 502 to circulate, and the inclined heat transfer plate 506 is cooled. When the liquid circulates, it enters the cylinder 503 and drives the fan 504 to rotate. The fan 504 drives the second rotating shaft 505 to rotate, and the second rotating shaft 505 drives the inclined heat transfer plate 506 to rotate. When the inclined heat transfer plate 506 is cooled, the steam contacted by the inclined heat transfer plate 506 condenses into droplets after being cooled.
[0030] A collecting box 3 is provided at one end of the top of the base 1, and a pipe 107 is provided on the top of the collecting box 3. The end of the pipe 107 is connected to the end of the water outlet 602. The inclined heat conduction plate 506 rotates to drive the droplets to be squeezed by the inclined plate 6. When the droplets are squeezed by the inclined plate 6, they will be adsorbed inside the No. 4 groove 601 in the inclined plate 6. Because the inner wall of the No. 4 groove 601 is provided with a groove, the droplets adsorbed inside the No. 4 groove 601 are intercepted by the groove.
[0031] In this embodiment: the arsenic in the main body 101 is heated by heating the heating ring 201, so that the liquid is vaporized into steam, and the steam floats to the top of the main body 101. When the steam floats upward and contacts the inclined plate 6, the inclined plate 6 itself will be driven to heat up by the temperature inside the main body 101, and the steam will not form liquid. The steam will float upward again and contact the surface of the inclined heat conduction plate 506. The circulating refrigeration pump 5 drives the liquid in the refrigeration tube 502 to circulate and cool the inclined heat conduction plate 506. When the liquid circulates, it enters the cylinder 503 and drives the fan 504 to rotate. The fan 504 drives the second rotating shaft 505 to rotate. The second rotating shaft 505 drives the inclined heat conduction plate 506 to rotate. When the inclined heat conduction plate 506 is cooled, the steam contacted by the inclined heat conduction plate 506 condenses into droplets after being cooled. The inclined heat conduction plate 506 rotates and drives the droplets to contact the top of the inclined plate 6, so that the droplets in the inclined heat conduction plate 506 are scraped by the top of the inclined plate 6. When the droplets are scraped by the inclined plate 6, they will be adsorbed inside the fourth groove 601 in the inclined plate 6.
[0032] Because the inner wall of the fourth tank 601 is provided with a groove, the liquid droplets adsorbed inside the fourth tank 601 are intercepted by the groove, and because the inclined plate 6 is at an inclined angle, the liquid droplets inside the fourth tank 601 will be discharged from the water outlet 602, and then enter the collection box 3 through the pipeline 107. When the circulating refrigeration pump 5 is in motion, the circulating refrigeration pump 5 itself will generate a certain vibration, and the vibration of the circulating refrigeration pump 5 drives the oblique heat conduction plate 506 at the bottom of the top plate 4 to vibrate, so that the liquid droplets are more likely to fall along the inclined surface of the oblique heat conduction plate 506 to the oblique plate 6 for collection and then be discharged from the water outlet 602.
[0033] Please refer to Figure 3-4 A No. 2 groove 105 is provided at the top of the main body 101, a No. 3 groove 106 is provided at the bottom of the No. 2 groove 105, a telescopic ring 407 is fixed to the outer side of the bottom of the top plate 4, a spring 409 is provided inside the telescopic ring 407, the spring 409 pulls the top plate 4 to contact the top of the main body 101, and a rubber ring is provided on the top of the main body 101 to prevent the bolts and the threaded rings from expanding and contracting during multiple heating and cooling, resulting in problems with the sealing of the top plate 4 and the main body 101.
[0034] A No. 2 annular groove 408 is provided on the top of the telescopic ring 407, a wedge-shaped block plate 410 is fixed to the bottom of the telescopic ring 407, a No. 1 annular groove 403 is provided on the outer side of the top of the top plate 4, an annular block plate 404 is provided inside the No. 1 annular groove 403, a curved groove 406 is provided on the outer side of the annular block plate 404, a swivel 402 is fixed to the top of the annular block plate 404, the end of the No. 1 rotating shaft 405 is slidably connected to the inside of the curved groove 406, and the inner wall of the No. 1 annular groove 403 is connected to the No. 1 rotating shaft 405.
[0035] The rotating ring 402 is rotated, and the rotating ring 402 drives the annular block plate 404 to move inside the No. 1 annular groove 403. When the annular block plate 404 rotates, the curved groove 406 is squeezed by the No. 1 rotating shaft 405, so that the annular block plate 404 moves downward, and the annular block plate 404 drives the wedge-shaped block plate 410 at the bottom of the telescopic ring 407 to move downward and engage with the No. 3 groove 106, so as to install the top plate 4 and the main body 101. The top plate 4 is pulled into contact with the top of the main body 101 by the spring 409, and a rubber ring is arranged on the top of the main body 101 to prevent the bolts and the threaded rings from expanding and contracting during multiple heating and cooling, resulting in problems with the sealing of the top plate 4 and the main body 101.
[0036] Working principle: high-purity arsenic to be distilled is placed in the main body 101 of the distillation device through the feed inlet, and the items in the main body 101 are heated by heating the heating ring 201 to vaporize the liquid into steam. The steam floats to the top of the main body 101. When the steam floats upward and contacts the inclined plate 6, the inclined plate 6 itself will be driven to heat up by the temperature inside the main body 101, and the steam will not form liquid. The steam will float upward again into the interior of the fourth tank 601, contact the surface of the inclined heat conduction plate 506, and drive the liquid in the refrigeration pipe 502 to circulate through the circulating refrigeration pump 5, and cool the inclined heat conduction plate 506. When the liquid circulates, it enters the cylinder 503 to drive the fan 504 to rotate, and the fan 5 04 drives the second rotating shaft 505 to rotate, and the second rotating shaft 505 drives the inclined heat conducting plate 506 to rotate. When the inclined heat conducting plate 506 is cooled, the inclined heat conducting plate 506 drives the droplets to contact the top of the inclined plate 6, so that the droplets in the inclined heat conducting plate 506 are scraped by the top of the inclined plate 6. When the droplets are scraped by the inclined plate 6, they will be adsorbed inside the No. 4 slot 601 in the inclined plate 6. Because the inner wall of the No. 4 slot 601 is provided with a groove, the droplets adsorbed inside the No. 4 slot 601 are intercepted by the groove to prevent the liquid generated by the mist from falling into the liquid being distilled again. Because the inclined plate 6 is at an inclined angle, the droplets inside the No. 4 slot 601 will be discharged from the water outlet 602, and then enter the collection box 3 through the pipeline 107 to obtain ultra-high purity arsenic.
[0037] By setting the heat insulation ring plate 507, when the inclined plate 6 itself is driven by the temperature inside the main body 101 to heat up and the inclined heat conduction plate 506 to cool down, the heat insulation ring plate 507 is effectively isolated to prevent the temperature of the inclined heat conduction plate 506 from affecting the temperature of the inclined plate 6. When the circulating refrigeration pump 5 is in motion, the circulating refrigeration pump 5 itself will generate a certain vibration. The vibration of the circulating refrigeration pump 5 drives the inclined heat conduction plate 506 at the bottom of the top plate 4 to vibrate, making it easier for droplets to be discharged from the water outlet 602.
[0038] Align the bottom of the telescopic ring 407 in the top plate 4 with the No. 2 groove 105, rotate the swivel 402, and the swivel 402 drives the annular block plate 404 to move inside the No. 1 annular groove 403. When the annular block plate 404 rotates, the curved groove 406 is squeezed by the No. 1 rotating shaft 405, so that the annular block plate 404 moves downward, and the annular block plate 404 drives the wedge-shaped block plate 410 at the bottom of the telescopic ring 407 to move downward and engage with the No. 3 groove 106, so as to install the top plate 4 and the main body 101. The top plate 4 is pulled into contact with the top of the main body 101 by the spring 409, and a rubber ring is provided on the top of the main body 101 to prevent the bolts and the threaded rings from expanding and contracting during multiple heating and cooling, resulting in problems with the sealing of the top plate 4 and the main body 101.

The steam floats upward again into the interior of the fourth tank (601), contacts the surface of the inclined heat conduction plate (506), and drives the liquid in the refrigeration pipe (502) to circulate through the circulating refrigeration pump (5), thereby cooling the inclined heat conduction plate (506); S2: When the liquid circulates, it enters the cylinder (503) and drives the fan (504) to rotate. The fan (504) drives the second rotating shaft (505) to rotate. The second rotating shaft (505) drives the inclined heat conducting plate (506) to rotate. When the inclined heat conducting plate (506) cools down, the steam contacted by the inclined heat conducting plate (506) condenses into liquid droplets after being cooled. The liquid droplets are squeezed by the inclined plate (6) through the rotation of the inclined heat conducting plate (506). When the inclined plate (6) is squeezed, the liquid droplets are adsorbed inside the No. 4 groove (601) in the inclined plate (6). Since the inner wall of the No. 4 groove (601) is provided with a groove, the liquid droplets adsorbed inside the No. 4 groove (601) are intercepted by the groove, thereby preventing the liquid generated by the mist from falling into the liquid being distilled again. Since the inclined plate (6) is at an inclined angle, the liquid droplets inside the No. 4 groove (601) are discharged from the water outlet (602) and enter the collection box (3) through the pipeline (107) again. S3: By setting up the heat-insulating ring plate (507), when the inclined plate (6) itself is driven by the temperature inside the main body (101) to heat up and the inclined heat-conducting plate (506) to cool down, the heat-insulating ring plate (507) is effectively isolated to prevent the temperature of the inclined heat-conducting plate (506) from affecting the temperature of the inclined plate (6). When the circulating refrigeration pump (5) is in motion, the circulating refrigeration pump (5) itself will generate a certain vibration. The vibration of the circulating refrigeration pump (5) drives the inclined heat-conducting plate (506) at the bottom of the top plate (4) to vibrate, making it easier for droplets to be discharged from the water outlet (602).
