[0002] An evaporator is essentially a heat exchanger. Inside the evaporator, heat exchange occurs between the material and the heat source. Part of the solvent in the material becomes gaseous and is separated, and the concentration of the material increases to achieve the purpose of evaporation and concentration. During the evaporation and concentration of nitric acid, a device is also needed to evaporate nitric acid. However, existing evaporation devices have some deficiencies. For example:

[0003] A method and device for denitrifying and evaporating and concentrating radioactive nitric acid waste liquid with the publication number of CN116013569A eliminates the phenomenon of bumping by introducing nitrogen oxide gas during the denitrifying evaporation reaction of radioactive nitric acid waste liquid. And during the denitrifying evaporation reaction of radioactive nitric acid waste liquid, there is no salt and no impurity ions are introduced. It has the characteristics of stable process, wide applicability, and less equipment modification. However, during actual use, since this device requires a variety of adjustment mechanisms to add raw materials such as nitric acid and gas, it may be difficult to adjust the amounts of gas and nitric acid during actual use of this device, and during the evaporation and concentration process, there may be a situation of excessive energy consumption;

[0004] Therefore, we propose an efficient and energy-saving nitric acid evaporation and concentration device to solve the problems mentioned above. Summary of the Invention

[0026] When the heating cylinder finishes heating the pure oxygen inside, the pure oxygen will be input into the evaporation chamber. Since the drive motor is rotating at this time, the lower ratchet and the upper ratchet will be engaged and fixed, so that the upper ratchet drives the connecting shaft and the air-dispersing impeller to rotate.

[0042] The top of the liquid storage chamber 1 is connected to an infusion tube 17, and the top of the liquid storage chamber 1 is connected to a first fixing plate 18. The first fixing plate 18 fixes the infusion tube 17. The top of the first fixing plate 18 is connected to a first peristaltic pump rod 19, and the top of the first peristaltic pump rod 19 is connected to a first rotating shaft 20. A second spring shaft 21 is arranged outside the first rotating shaft 20. The outside of the second spring shaft 21 is connected to a first clamping block 22. The top of the first rotating shaft 20 is connected to a second rotating shaft 24. A third spring shaft 25 is arranged outside the second rotating shaft 24. The outside of the third spring shaft 25 is connected to a second clamping block 26. The top of the second rotating shaft 24 is connected to a second peristaltic pump rod 28. The top of the second peristaltic pump rod 28 is connected to a second fixing plate 30. The bottom of the second fixing plate 30 is connected to an air delivery tube 29. The air delivery tube 29 is in contact with the second peristaltic pump rod 28. The air delivery tube 29 is connected to the heating cylinder 8. The infusion tube 17 is connected to the bottom of the evaporation chamber 2;

[0043] The left side of the first gear 7 meshes with a second gear 15. The second gear 15 is internally connected to a rotating ring 16. A first ratchet groove 23 is arranged at the bottom inside the rotating ring 16. The first ratchet groove 23 can be snap-connected with the first clamping block 22. The top inside the rotating ring 16 is connected to a second ratchet groove 27. The second ratchet groove 27 can be snap-connected with the second clamping block 26;

[0044] The top of the liquid storage chamber 1 is connected to a fixing ring 38. The fixing ring 38 is slidably connected to the outside of the rotating ring 16. A steam collector 34 is arranged at the top of the evaporation chamber 2. A detection mechanism is arranged on the right side of the evaporation chamber 2. A discharge port 31 is arranged at the bottom of the evaporation chamber 2;

[0045] When using the nitric acid evaporation and concentration device, first, the nitric acid liquid is transmitted into the liquid storage chamber 1 through the infusion valve 3. Subsequently, the driving motor 6 is started, so that the driving motor 6 drives the first gear 7 to rotate counterclockwise. Since the first gear 7 meshes with the second gear 15, the second gear 15 will rotate clockwise, so that the first ratchet groove 23 arranged at the bottom of the rotating ring 16 drives the first clamping block 22 to snap and rotate. The first clamping block 22 rotates with the first rotating shaft 20 as the center and drives the first rotating shaft 20 to rotate. Thus, the first rotating shaft 20 drives the first peristaltic pump rod 19 to rotate, squeezing the infusion tube 17. Due to extrusion and pressure, the nitric acid liquid inside the liquid storage chamber 1 is discharged into the evaporation chamber 2 through the infusion tube 17;

[0046] When the nitric acid liquid inside the evaporation chamber 2 reaches a specified height, the driving motor 6 drives the first gear 7 to rotate clockwise, enabling the second gear 15 to drive the rotating ring 16 to rotate counterclockwise. At this time, the first ratchet groove 23 will disconnect from the first latch 22, and the first latch 22 will retract under the drive of the second spring shaft 21. The first rotating shaft 20 will not drive the first peristaltic pump rod 19 to rotate, while the rotating ring 16 will drive the second ratchet groove 27 to rotate counterclockwise, causing the second ratchet groove 27 to engage with the second latch 26 and drive the second latch 26 to rotate around the second rotating shaft 24 as the center, thereby causing the second rotating shaft 24 and the second peristaltic pump rod 28 to rotate, enabling the second peristaltic pump rod 28 to fit and squeeze the gas transmission pipe 29, so that the gas transmission pipe 29 transports pure oxygen or other gases into the heating cylinder 8;

[0047] When the first gear 7 rotates counterclockwise, the lower ratchet 10 will disconnect from the upper ratchet 12, and the upper ratchet 12 will retract upward under the drive of the first spring shaft 11. When the first gear 7 rotates clockwise, the lower ratchet 10 will engage with the upper ratchet 12, thereby enabling the first gear 7 to drive the connecting shaft 13 and the air-diffusing impeller 14 to rotate, causing the heated gas to be cut into smaller bubbles by the air-diffusing impeller 14 after forming bubbles through the one-way valve 9;

[0048] The detection mechanism includes a U-shaped tube 32, and the U-shaped tube 32 is fixedly connected to the evaporation chamber 2, and a concentration detector 33 is provided in the middle of the U-shaped tube 32; a filter block 5 is connected to the bottom of the liquid storage chamber 1, and a sedimentation chamber 4 is connected to the bottom of the filter block 5, and the sedimentation chamber 4 is connected to the infusion valve 3; a fixed rod 37 is connected to the top of the liquid storage chamber 1, and the liquid storage chamber 1 is fixedly connected to the evaporation chamber 2 through the fixed rod 37;

[0049] The heating cylinder 8 is internally provided with a heating resistance wire, and the inner top of the heating cylinder 8 is fixedly connected to the one-way valve 9; the ratchet groove positions of the first ratchet groove 23 and the second ratchet groove 27 are opposite, and the orientations of the first latch 22 and the second latch 26 are opposite; a corrugated pipe 35 is provided on the right side of the steam collector 34, and the corrugated pipe 35 is internally provided with corrugated-shaped slots; a condensate discharge port 36 is provided at the bottom left end of the corrugated pipe 35, and the condensate discharge port 36 is fixedly connected to the corrugated pipe 35; the bottom of the liquid storage chamber 1 is provided with feet, and heat insulation wall mechanisms are provided on the inner sides of both the liquid storage chamber 1 and the evaporation chamber 2;

[0050] When the infusion valve 3 transfers nitric acid liquid to the liquid storage bin 1, the nitric acid liquid will pass through the precipitation bin 4, and the impurities inside the nitric acid liquid will be filtered out by the filter block 5, so that the impurities in the nitric acid liquid will be reduced when it is transferred to the liquid storage bin 1. When the nitric acid liquid in the evaporation bin 2 reaches a certain water level, the excess liquid will be transferred to the U-shaped tube 32 and detected by the concentration detector 33, so as to judge the concentration of the nitric acid liquid. When the evaporation bin 2 discharges steam, the steam will enter the corrugated pipe 35 through the steam collector 34. Due to the corrugated grooves provided inside the corrugated pipe 35, the contact area of the steam will increase, so that the corrugated grooves will adsorb the condensed water and drain it into the condensed water discharge port 36 through the flow direction.

[0051] Working principle: When using the nitric acid evaporation and concentration equipment, first transfer the nitric acid liquid to the inside of the liquid storage bin 1 through the infusion valve 3, and then start the drive motor 6, so that the drive motor 6 drives the first gear 7 to rotate counterclockwise. Since the first gear 7 meshes with the second gear 15, the second gear 15 will rotate clockwise, so that the first ratchet groove 23 provided at the bottom of the rotating ring 16 drives the first latch 22 to engage and rotate, so that the first latch 22 rotates around the first rotating shaft 20 as the center and drives the first rotating shaft 20 to rotate. Thus, the first rotating shaft 20 drives the first peristaltic pump rod 19 to rotate, squeezes the infusion tube 17, so that the infusion tube 17 discharges the nitric acid liquid inside the liquid storage bin 1 into the evaporation bin 2 due to extrusion and pressure;

[0052] When the nitric acid liquid in the evaporation bin 2 reaches the specified height, the drive motor 6 drives the first gear 7 to rotate clockwise, which can make the second gear 15 drive the rotating ring 16 to rotate counterclockwise. At this time, the first ratchet groove 23 will disconnect from the first latch 22, and the first latch 22 will retract under the drive of the second spring shaft 21, and the first rotating shaft 20 will not drive the first peristaltic pump rod 19 to rotate, while the rotating ring 16 will drive the second ratchet groove 27 to rotate counterclockwise, so that the second ratchet groove 27 engages with the second latch 26 and drives the second latch 26 to rotate around the second rotating shaft 24 as the center, so that the second rotating shaft 24 and the second peristaltic pump rod 28 rotate, so that the second peristaltic pump rod 28 fits and squeezes the gas transmission tube 29, so that the gas transmission tube 29 transfers pure oxygen or other gases to the inside of the heating cylinder 8;

[0053] When the first gear 7 rotates counterclockwise, the lower ratchet 10 will disconnect from the upper ratchet 12, and the upper ratchet 12 will retract upward under the drive of the first spring shaft 11. When the first gear 7 rotates clockwise, the lower ratchet 10 will engage with the upper ratchet 12, so that the first gear 7 drives the connecting shaft 13 and the air-dispersing impeller 14 to rotate, so that the heated gas is cut into smaller bubbles by the air-dispersing impeller 14 after forming bubbles through the one-way valve 9;

[0054] When the infusion valve 3 transfers nitric acid liquid to the liquid storage bin 1, the nitric acid liquid will pass through the precipitation bin 4, and the impurities in the nitric acid liquid will be filtered out by the filter block 5, so that the impurities in the nitric acid liquid will be reduced when it is transferred to the liquid storage bin 1. When the nitric acid liquid in the evaporation bin 2 reaches a certain water level, the excess liquid will be transferred to the U-shaped tube 32 and detected by the concentration detector 33, so as to judge the concentration of the nitric acid liquid. When the evaporation bin 2 discharges steam, the steam will enter the corrugated pipe 35 through the steam collector 34. Due to the corrugated grooves provided inside the corrugated pipe 35, the contact area of the steam will increase, so that the corrugated grooves will adsorb the condensed water and drain it into the condensed water discharge port 36 through the flow direction.

[0055] Thus, a series of operations are completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
