Description

Technical Field

[0001] The invention relates to the technical field of potassium superoxide production, in particular to a liquid potassium atomizing nozzle in the potassium superoxide production process. Background Art

[0002] Potassium superoxide, a primary oxidant, can be used as an oxygen generator in aerospace, submarine technology, mine emergency and other fields. In a closed environment, the carbon dioxide and water produced by human breathing can react with potassium superoxide to produce oxygen necessary for human survival.

[0003] In the traditional preparation process of potassium superoxide, potassium hydroxide and hydrogen peroxide are generally used as raw materials for reaction. However, the potassium superoxide powder produced by the above preparation method has a low purity, so people have adopted a method of preparing potassium superoxide by reacting metallic potassium and oxygen under a high temperature environment. For example, the Chinese patent published on April 6, 2018, with the publication number CN107879361A, discloses "a method for preparing potassium superoxide powder by metallic potassium spray oxidation", and its technical content is: "It includes the following steps: liquid potassium and compressed air are atomized through an inner and outer nested spray gun to obtain potassium superoxide powder; the spray gun includes an outer cavity for compressed air flow, and an inner cavity for liquid potassium flow; the flow rate of compressed air is 6-8 m / s, and the flow rate of liquid potassium is 0.3-0.5 m / s; the reaction temperature of liquid potassium and compressed air is 260-300°C. The oxygen content of the potassium superoxide powder prepared by the above method is greater than 31%, and the bulk density can reach 0.565g / cm 3 The potassium superoxide powder prepared by the above method can be used to produce 65-type potassium air regeneration medicine board and oxygen generator in isolated self-rescuer.

[0004] However, the above method has the following defects: the liquid potassium starts to react with oxygen before it diffuses after being ejected from the inner cavity, which results in the liquid potassium being unable to fully contact with oxygen, thereby causing the liquid potassium to be unable to fully react with oxygen, resulting in an increase in by-products, such as potassium oxide and potassium peroxide. Summary of the invention

[0005] In view of the above defects, the purpose of the present invention is to provide a liquid potassium atomizing nozzle in the production process of potassium superoxide, aiming to solve the problem in the prior art that liquid potassium cannot fully contact with oxygen, resulting in an increase in by-products.

[0006] In order to solve the above technical problems, the technical solution of the present invention is:

[0033] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0034] Embodiment 1:

[0035] like Figure 1-7 As shown, in order to ensure that the liquid potassium can fully contact with oxygen, we need to diffuse the liquid potassium to the maximum extent to ensure the contact area between the liquid potassium and oxygen. To this end, a liquid potassium atomizing nozzle in the production process of potassium superoxide includes a transfer pipe 1 and a sealing shell 2, wherein the sealing shell 2 includes an inner cavity 21 and an annular fixed platform 22, and the outer wall of the transfer pipe 1 is provided with a clamping table 11. In order to prevent the transfer pipe 1 from hindering the rotation of the sealing shell 2, the clamping table 11 is rotatably connected with the annular fixed platform 22, and one end of the transfer pipe 1 is located in the inner cavity 21. This design enables the sealing shell 2 to rotate, thereby throwing the liquid potassium to the surroundings of the sealing shell 2, so that the liquid potassium can cover a larger area.

[0036] In order to facilitate the rotation of the sealed shell 2, a plurality of jet ports 23 are provided on the outer wall of the sealed shell 2, wherein the jet ports 23 are circumscribed with the inner cavity 21, and one end of the jet ports 23 is connected to the inner cavity 21, and the other end of the jet ports 23 extends toward the outer wall of the sealed shell 2. When the liquid potassium is ejected through the jet ports 23, the liquid potassium will exert a reaction force on the jet ports 23, and the reaction force will increase as the flow rate of the liquid potassium increases. When the reaction force is large enough, the liquid potassium will push the sealed shell 2 to rotate in the opposite direction of the ejection direction during the ejection process. When the sealed shell 2 rotates, centrifugal force will be exerted on the liquid potassium, which enables the liquid potassium to be distributed over a larger range.

[0037] Since liquid potassium forms small droplets when it is sprayed out, the larger the distribution range of the liquid potassium, the farther the distance between the small droplets will be. At this time, there will be enough oxygen around the small droplets to react with the metallic potassium to form potassium superoxide, reducing the generation of secondary reactants.

[0038] In this embodiment, the plurality of jet ports 23 are arranged clockwise or counterclockwise at the same time.

[0039] In order to further accelerate the speed of liquid potassium ejecting from the jet port 23, the jet port 23 includes a first segment 231, a second segment 232 and a third segment 233, wherein the first segment 231 is connected to the inner cavity 21, the second segment 232 is located between the first segment 231 and the third segment 233, the inner diameter of the first segment 231 is a, the inner diameter of the second segment 232 is b, and the inner diameter of the third segment 233 is c, where c≥a>b. This design enables the jet port 23 to form a structure similar to a Laval nozzle, and when the high-flow liquid potassium reaches the second segment 232 from the first segment 231, the high-speed flowing liquid potassium will further accelerate the flow speed due to the reduction in the inner diameter. When the high-speed flowing liquid potassium reaches the third segment 233 from the second segment 232, its flow speed is further accelerated, which enables the liquid potassium to have enough power to eject from the jet port 23, and at the same time, the sealed shell 2 will also be subjected to a sufficiently large reaction force.

[0040] In order to facilitate the full contact between liquid potassium and oxygen, we can reduce the volume of small droplets formed by liquid potassium. For this purpose, the end of the third section 233 away from the second section 232 is covered with a first atomization net 234. The first atomization net 234 is provided with a plurality of meshes. When the liquid potassium collides with the first atomization net 234 during the spraying process, the liquid potassium will be broken and split into a plurality of small droplets of smaller volume, which increases the atomization degree of the liquid potassium.

[0041] When the liquid potassium collides with the first atomizing net 234 during the flow, the number of small droplets generated will also be limited due to the limited number of meshes of the first atomizing net 234. In order to improve this problem, the flowing liquid potassium can be dispersed in multiple stages. For this purpose, the end of the adapter pipe 1 facing the inner cavity 21 is covered with a second atomizing net 12.

[0042] In order to increase the number of small droplets, multiple mesh structures can be set in the multi-stage dispersion process of liquid potassium, such as the first atomization net 234 and the second atomization net 12. In order to further increase the number of small droplets, we need to control the mesh aperture of the mesh structure. For this purpose, the inner diameter of the mesh of the second atomization net 12 is 1.5-2 times the inner diameter of the mesh of the first atomization net 234.

[0043] Although the above structure enables small droplets to be sprayed around through the jet port 23, it is limited by the aperture of the jet port 23. When the flow rate of liquid potassium is too fast, part of the liquid potassium will accumulate at the bottom of the inner cavity 21. In order to allow this part of the liquid potassium to reach the outside together, the inner cavity 21 in this solution is conical, and a plurality of jet ports 24 are provided at the bottom of the inner cavity 21. One end of the jet port 24 extends toward the outer wall of the sealing shell 2; the end of the jet port 24 away from the inner cavity 21 is covered with a third atomization net 243. The top area of ​​the conical inner cavity 21 in this solution is larger than its bottom area, which makes it easier for the accumulated liquid potassium to converge toward the bottom of the inner cavity 21, and then the liquid potassium can pass through the jet port 24 to reach the third atomization net 243, so that the accumulated liquid potassium can be split into more small droplets and sprayed out.

[0044] If too much liquid potassium flows out through the bottom, the liquid potassium flowing out through the jet port 23 will be reduced, resulting in a decrease in the rotation speed of the sealed shell 2. Therefore, we need to control the flow rate of the liquid potassium through the jet port 24. To this end, Figure 2 , 5 As shown in Figures 6 and 7, the injection port 24 includes an adjusting section 241 and an atomizing section 242. The two ends of the adjusting section 241 are respectively connected to the atomizing section 242 and the inner cavity 21. A flow regulating mechanism 25 is installed in the atomizing section 242. The flow regulating mechanism 25 includes a sealing plate 251 and a plug 252. The plug 252 is located at one end of the sealing plate 251 facing the adjusting section 241. The outer diameter of the sealing plate 251 is larger than the inner diameter of the adjusting section 241, and the outer diameter of the sealing plate 251 is smaller than the inner diameter of the atomizing section 242. The plug 252 is slidably arranged in the adjusting section 241. When the pressure of the liquid potassium in the inner cavity 21 is relatively large, the liquid potassium will enter the adjusting section 241 and squeeze the plug 252, forcing the plug 252 and the sealing plate 251 to move toward the atomizing section 242, leaving space for the liquid potassium to enter the atomizing section 242.

[0045] In this solution, liquid potassium will be sprayed out through the nozzle together with the inert gas. Therefore, when the liquid potassium is interrupted, the flow rate of the inert gas can be increased. At this time, the inert gas will still carry the liquid potassium to squeeze the flow regulating mechanism 25, so that the liquid potassium accumulated in the inner cavity 21 is discharged. Therefore, there is no need to worry about the liquid potassium accumulating in the inner cavity 21 due to insufficient pressure.

[0046] To facilitate the resetting of the flow regulating mechanism 25, a plurality of limiting columns 253 are installed on the sealing plate 251, and a plurality of limiting grooves 254 cooperating with the limiting columns 253 are provided at one end of the atomizing section 242 facing the regulating section 241. The plurality of limiting columns 253 are arranged around the plug 252, and the limiting columns 253 are slidably arranged in the limiting grooves 254. A limiting spring 255 is installed between one end of the limiting column 253 away from the sealing plate 251 and the bottom of the limiting groove 254.

[0047] Liquid potassium will adhere to the limiting column 253 when passing through the sealing plate 251, and the limiting column 253 will bring the liquid potassium into the limiting groove 254 during the up and down movement. In order to avoid this problem, the limiting groove 254 is provided with a third annular groove 256 at one end close to the sealing plate 251, and the outer wall of the limiting column 253 is provided with a fourth annular groove 257 that cooperates with the third annular groove 256. A second sealing ring 258 is provided in the third annular groove 256, and a part of the second sealing ring 258 is located between the third annular groove 256 and the limiting column 253. This design allows the limiting column 253 to continuously rub against the second sealing ring 258 during the up and down movement of the limiting column 253, so that the second sealing ring 258 will scrape off the liquid potassium attached to the surface of the limiting column 253.

[0048] like Figure 2 , 4 As shown in Figure 8, in order to facilitate the rotational connection between the adapter pipe 1 and the sealing shell 2, an annular groove is provided at the end of the annular fixing platform 22 away from the inner cavity 21, and a clamping plate 26 is provided on the top of the annular groove. An annular avoidance area 261 is provided at the end of the clamping plate 26 facing the inner cavity 21. The clamping platform 11 is rotatably set between the annular avoidance area 261 and the annular groove, and the clamping plate 26 is bolted to the annular groove.

[0049] In order to reduce the friction force when the sealing shell 2 rotates, an annular bottom groove 262 is provided at the bottom of the avoidance area. A plurality of wear-resistant balls 263 are arranged in the annular bottom groove 262 , and a part of the wear-resistant balls 263 is in contact with the clamping table 11 .

[0050] In order to ensure air tightness and prevent liquid potassium from reaching the outside through the gap between the sealing shell 2 and the adapter pipe 1, a sealing gasket 13 is provided on the outer wall of the adapter pipe 1, and a positioning groove 14 is provided on the inner wall of the annular fixing platform 22, and a partial area of ​​the sealing gasket 13 is located in the positioning groove 14.

[0051] Embodiment 2:

[0052] like Fig. 9 As shown, in this solution, the plug 252 is conical, and a first annular groove 259 is provided on the outer wall of the plug 252. The inner wall of the adjustment section 241 is provided with a second annular groove (not shown in the figure) that matches the first annular groove 259. A first sealing ring 260 is installed in the second annular groove, and the first sealing ring 260 is located between the second annular groove and the plug 252. The first sealing ring 260 is installed in the second annular groove. When the plug 252 moves up and down, the first sealing ring 260 will scrape the liquid potassium on the plug 252 to prevent the liquid potassium from adhering to the plug 252. At the same time, this design also increases the air tightness of the plug 252.

[0053] Embodiment 3:

[0054] like Fig.10 As shown, this scheme adopts an inert gas-assisted liquid potassium spraying scheme to ensure that the liquid potassium has enough power to be thrown around the sealed shell 2, and also has enough power to drive the sealed shell 2 to rotate. To this end, the nozzle also includes a mounting platform 3, one end of the mounting platform 3 is connected to the end of the adapter pipe 1 away from the sealed shell 2, and the end of the mounting platform 3 away from the sealed shell 2 is installed with an air induced channel 31, and a liquid outlet pipe 32 is arranged in the air induced channel 31. An air inlet pipe 33 is installed on the side wall of the air induced channel 31, and the end of the liquid outlet pipe 32 away from the sealed shell 2 is connected to a liquid inlet pipe 34. The air inlet pipe 33 introduces a high-flow inert gas into the air induced channel 31, and the liquid inlet pipe 34 transports the liquid potassium to the liquid outlet pipe 32. When the liquid outlet pipe 32 sprays liquid potassium, the high-flow inert gas will carry the liquid potassium forward together, thereby accelerating the flow rate of the liquid potassium.

[0055] The inert gas in this solution is preferably argon, which is easy to obtain and has a low cost. At the same time, argon does not react with potassium, so it is suitable for assisting the flow of liquid potassium.

[0056] Preferably, an annular air duct 35 is provided on the circumference of the air inlet channel 31, and one end of the air inlet duct 33 away from the air inlet channel 31 is connected to the annular air duct 35, and a plurality of the air inlet ducts 33 are provided, and the plurality of the air inlet ducts 33 are arranged around the air inlet channel 31. This design enables the inert gas in the air inlet duct to form a spiral airflow, which causes the inert gas to drive the liquid potassium to continuously collide during the flow process, forming more small droplets.

[0057] In order to prevent the inert gas from solidifying due to the low temperature of the inert gas, we need to heat the inert gas. To this end, a medium heat pipe 36 is provided in the mounting platform 3, and the medium heat pipe 36 is arranged around the air induction channel 31. The two ends of the medium heat pipe 36 are respectively provided with a medium inlet 361 and a medium outlet 362. The medium inlet 361 introduces the high-temperature medium into the medium heat pipe 36, and the medium is discharged through the medium outlet 362 after flowing for a period of time. In this process, the high-temperature medium will exchange heat with the mounting platform 3 to heat the inert gas and the liquid potassium.

[0058] Embodiment 4:

[0059] like Fig.11 As shown, the difference between this embodiment and embodiment 3 is that: the air induction channel 31 includes a first channel 311, a second channel 312 and a third channel 313 connected in sequence, the liquid outlet pipe 32 is located in the first channel 311, the annular air duct 35 is arranged around the first channel 311, the inner diameter of the first channel 311 is d, the inner diameter of the second channel 312 is e, and the inner diameter of the third channel 313 is f, d≥f>e. This design is similar to the structure of the jet port 23, both of which are Laval nozzle structures, and their purpose is to accelerate the flow rate of the inert gas and liquid potassium.

[0060] Preferably, an atomizing net is installed on one end of the third channel 313 facing the sealed shell 2 and one end of the liquid outlet pipe 32 facing the sealed shell 2.

[0061] In summary, this solution has the following advantages: First, the sealing shell 2 is rotatably connected to the adapter pipe 1, and the jet port 23 is circumscribed with the inner cavity 21. This design makes it possible for the liquid potassium to cause a reaction force on the sealing shell 2 when the jet port 23 sprays liquid potassium, thereby driving the sealing shell 2 to rotate, which enables the liquid potassium to cover a larger range, thereby ensuring that the liquid potassium is in full contact with oxygen. Second, the jet port 23 is composed of a first segment 231, a second segment 232, and a third segment 233 with different inner diameters, which forms a Laval nozzle structure inside the jet port 23, thereby further accelerating the ejection speed of the liquid potassium.

[0062] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work are all within the protection scope of the present invention.
