Description

Technical Field

[0001] The present invention belongs to the technical field of condensers for nitrous oxide production, specifically condensers for liquefying nitrous oxide in production. Background Art

[0002] Nitrous oxide, also known as dinitrogen monoxide, has the chemical formula N 2 ₂O, is a colorless gas with a sweet taste. It is an oxidizing agent, a combustion-supporting agent, and an anesthetic, mainly used in fields such as medicine, food additives, and electronic product production. While carbon monoxide has the chemical formula CO, is a colorless, odorless, and non-irritating gas, mainly derived from incomplete combustion processes, and is toxic, having a serious impact on human health.

[0003] When nitrous oxide is produced, it is generally produced by a condensation method, thus requiring the use of a condenser for liquefying nitrous oxide in production.

[0004] When some existing condensers for liquefying nitrous oxide in production are in use, generally a hydraulic rod is used to squeeze a piston downward, so that the liquefied nitrous oxide around it is scraped downward through a hanging ring, pushing the liquefied nitrous oxide on the inner wall of the liquefaction pipe downward and flowing out through a liquid outlet pipe, accelerating the downward flow rate of the liquefied nitrous oxide, and at the same time avoiding waste caused by uncollected liquefied nitrous oxide remaining on the inner wall, thereby increasing the output during the production process and saving raw materials.

[0005] However, when some existing condensers for liquefying nitrous oxide in production are in use, although the liquefied nitrous oxide on the inner wall of the liquefaction pipe is pushed out by a hydraulic rod, during the condensation process of nitrous oxide, the crude nitrous oxide gas generated cannot be washed with water, so impurities in the crude nitrous oxide gas cannot be removed, resulting in impurities in the nitrous oxide after condensation, reducing the purity of the nitrous oxide, and thus reducing the quality of the nitrous oxide.

[0006] Therefore, the present invention provides a condenser for liquefying nitrous oxide in production. Summary of the Invention

[0019] 1. For the nitrous oxide production liquefaction condenser of the present invention, through the settings of structures such as the water washing mechanism, the caustic washing mechanism and the re-washing mechanism, the crude nitrous oxide gas is transported into the water washing cylinder. Through the setting of the two interconnected water washing cylinders, the crude nitrous oxide gas is washed twice with water, and the used washing water is discharged through the sewage pipe. The nitrous oxide after two water washings is transported into the primary caustic washing cylinder through the diversion pipe. Sodium hydroxide, potassium permanganate solution and domestic drinking water are respectively transported into the primary caustic washing cylinder and the secondary caustic washing cylinder through the caustic washing pipe. Through the setting of the interconnected primary caustic washing cylinder and secondary caustic washing cylinder, the nitrous oxide is caustic washed twice, thereby cleaning the impurities contained in the nitrous oxide and purifying the nitrous oxide gas, thus improving the quality of the nitrous oxide after condensation;

[0020] 2. The condenser for nitrous oxide production and liquefaction according to the present invention, through the setting of the re-washing mechanism, washes the nitrous oxide after alkali washing with drinking water again, making the nitrous oxide gas purer. Then, through the mutual cooperation of the molecular sieve and the filter box, the nitrous oxide gas is filtered, and the filtered nitrous oxide gas is detected through the sampling tube, which is convenient for controlling the quality of subsequent nitrous oxide condensation. And through the setting of bolts, the filter box is convenient for later disassembly, thus facilitating the replacement of the molecular sieve inside the filter box, making the use of the molecular sieve more convenient;

[0021] 3. The condenser for nitrous oxide production and liquefaction according to the present invention, through the mutual cooperation of structures such as the condensation mechanism and the cooling mechanism, fits the electromagnet and the permanent magnet, and makes the electromagnet energized, so that the electromagnet and the permanent magnet are magnetically attracted and fitted, making the connecting pipe and the ventilation pipe fixedly connected and sealed, so that the spiral pipe is communicated with the connecting pipe. The nitrous oxide after multiple water washes enters the inside of the spiral pipe through the connecting pipe. Through the setting of the cooling mechanism, the heat of the spiral pipe is absorbed, so that the nitrous oxide condenses into a liquid inside the spiral pipe. Thus, through the mutual cooperation of the electromagnet and the permanent magnet, after the electromagnet is powered off, the electromagnet and the permanent magnet are separated, and the cooling mechanism and components such as the spiral pipe are disassembled and cleaned, making the filter condensation mechanism more convenient to disassemble and making it more convenient to clean the filter condensation mechanism;

[0022] 4. The condenser for nitrous oxide production and liquefaction according to the present invention, through the setting of structures such as the extrusion mechanism, after the nitrous oxide condenses into a liquid through the spiral pipe, the liquid nitrous oxide is stored through the storage box, and through the setting of the detection pipe, it is convenient for the staff to sample and detect the liquid nitrous oxide inside the storage box. And when bottling the liquid nitrous oxide, place the steel cylinder under the discharge pipe, start the drive motor, make the threaded rod drive the sealing plate to move, change the air pressure inside the storage box, and extrude the liquid nitrous oxide inside the storage box through the discharge pipe, so that it is filled into the steel cylinder for packaging. Thus, by changing the air pressure, the liquefied nitrous oxide remaining in the storage box is avoided, not only avoiding the waste of nitrous oxide, but also avoiding the remaining nitrous oxide affecting the quality of the next condensation of liquid nitrogen oxide.

[0034] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0035] Refer to Figure 1 - Figure 9 , the present invention provides three technical solutions: Embodiment 1:

[0036] The condenser for the production of liquefied nitrous oxide includes a support assembly 1. Inside the support assembly 1, a water washing mechanism 2 is installed. On the surface of the water washing mechanism 2, an alkali washing mechanism 3 is installed. On the surface of the alkali washing mechanism 3, a re-washing mechanism 4 is installed. On the surface of the re-washing mechanism 4, a filtering and condensing mechanism 5 is installed. On the surface of the filtering and condensing mechanism 5, a discharging mechanism 6 is installed;

[0037] The water washing mechanism 2 includes two water washing cylinders 201 respectively installed on both sides of the surface of the support assembly 1. On one side of the surfaces of the two water washing cylinders 201, a gas guide pipe 207 communicating with an external existing reactor is fixedly connected. On the surface of one of the water washing cylinders 201, a diversion pipe 206 communicating with a secondary alkali washing cylinder 303 is fixedly connected. At one end of the two water washing cylinders 201, a water inlet pipe 202 is fixedly connected. On both sides of the surface of the water inlet pipe 202, valves 203 are installed. Through the setting of the valves 203, drinking water can enter the interiors of the two water washing cylinders 201 respectively according to the opening and closing of the valves 203. The water inlet pipe 202 is communicated with an external existing water pipe. On the upper surface of one of the water washing cylinders 201, an air inlet pipe 204 communicating with the other water washing cylinder 201 is fixedly connected. At the other end of the two water washing cylinders 201, a sewage pipe 205 communicating with a drain pipe 306 is fixedly connected.

[0038] The ammonium nitrate solution is added with diammonium hydrogen phosphate through a melting pot and reacts with a reactor to obtain a crude nitrous oxide gas. The crude nitrous oxide gas is transported into the interior of one of the water washing cylinders 201 through the gas guide pipe 207. By opening the valves 203, drinking water enters the interior of the water washing cylinder 201 through the water inlet pipe 202, and the crude nitrous oxide gas is subjected to a primary water wash. Through the setting of the air inlet pipe 204, the crude nitrous oxide gas after the primary water wash enters the interior of the other water washing cylinder 201 for a secondary water wash, so that the impurities in the crude nitrous oxide gas that react with water are removed from the nitrous oxide. Through the setting of the sewage pipe 205, the used drinking water is discharged from the water washing cylinder 201, facilitating the subsequent continuous use of the water washing mechanism 2.

[0039] The caustic washing mechanism 3 includes a primary caustic washing cylinder 301 installed on the surface of the water washing mechanism 2. A communicating pipe 302 is fixedly connected to the surface of the primary caustic washing cylinder 301. One end of the communicating pipe 302 is fixedly connected to a secondary caustic washing cylinder 303 that is connected to the primary caustic washing cylinder 301 through the communicating pipe 302. One end of the primary caustic washing cylinder 301 and the secondary caustic washing cylinder 303 are jointly fixedly connected to a three-way water pipe 304. Through the setting of the three-way water pipe 304, the caustic washing liquid can enter the interiors of the primary caustic washing cylinder 301 and the secondary caustic washing cylinder 303. One end of the three-way water pipe 304 is fixedly connected to a caustic washing pipe 305 that is respectively connected to the primary caustic washing cylinder 301 and the secondary caustic washing cylinder 303 through the three-way water pipe 304. Drain pipes 306 are fixedly connected to the other ends of the primary caustic washing cylinder 301 and the secondary caustic washing cylinder 303. A discharge pipe 307 with a check valve inside is fixedly connected to the lower surface of the secondary caustic washing cylinder 303. Through the setting of the check valve, the nitrous oxide after secondary caustic washing can only enter the interior of the re-washing cylinder 401 from the secondary caustic washing cylinder 303 through the discharge pipe 307 and cannot enter the interior of the secondary caustic washing cylinder 303 from the re-washing cylinder 401;

[0040] The nitrous oxide that has been washed twice with water is introduced into the interior of the primary caustic washing cylinder 301 through the diversion pipe 206. Sodium hydroxide, potassium permanganate solution, and domestic drinking water are respectively transported into the interiors of the primary caustic washing cylinder 301 and the secondary caustic washing cylinder 303 through the caustic washing pipe 305. The nitrous oxide is caustic washed by the primary caustic washing cylinder 301, and the nitrous oxide after primary caustic washing is transported to the interior of the secondary caustic washing cylinder 303 through the communicating pipe 302 for secondary caustic washing of the nitrous oxide, thereby further cleaning the impurities in the nitrous oxide and purifying the nitrous oxide, so that the quality of the produced nitrous oxide is improved. And through the setting of the drain pipe 306, the used caustic washing liquid is discharged from the primary caustic washing cylinder 301 and the secondary caustic washing cylinder 303, facilitating the caustic washing of nitrous oxide again;

[0041] The re-washing mechanism 4 includes a re-washing cylinder 401 fixedly connected to one end of the discharge pipe 307 and communicating with the discharge pipe 307. A sewage discharge pipe 402 communicating with the drain pipe 306 is fixedly connected to one end of the re-washing cylinder 401. An air outlet pipe 403 is fixedly connected to the other end of the re-washing cylinder 401. A water delivery pipe is installed on the surface of the re-washing cylinder 401. One end of the air outlet pipe 403 is fixedly connected to a hollow pipe 404.

[0042] Through the setting of the discharge pipe 307, the nitrous oxide after secondary caustic washing is transported into the interior of the re-washing cylinder 401. Drinking water is injected into the interior of the re-washing cylinder 401 through the water delivery pipe to wash the nitrous oxide again, so that the nitrous oxide is more pure. Then, the used drinking water is discharged through the sewage discharge pipe 402, and the nitrous oxide that has been washed with water is discharged through the hollow pipe 404. Embodiment 2:

[0043] The difference between this embodiment and the first embodiment is that the filtering and condensing mechanism 5 includes a filter box 501 fixedly connected to one end of the hollow tube 404 by bolts. A molecular sieve is provided inside the filter box 501. A carrier plate 502 is fixedly connected to the surface of the filter box 501 by bolts. A connecting pipe 503 is fixedly connected to one side of the filter box 501 by bolts. The two sides of the filter box 501 are respectively communicated with the connecting pipe 503 and the hollow tube 404. A sampling pipe 509 communicated with the filter box 501 is fixedly connected to the front of the filter box 501. Through the setting of the sampling pipe 509, it is convenient for the staff to sample and detect the nitrous oxide gas inside the filter box 501, so as to facilitate the control of the quality of nitrous oxide production;

[0044] The nitrous oxide discharged through the hollow tube 404 enters the inside of the filter box 501, and the nitrous oxide is filtered by the molecular sieve, so that the nitrous oxide is purer. Then, the filtered nitrous oxide is discharged through the connecting pipe 503. Through the setting of bolts, the filter box 501 can be disassembled, which is convenient for the staff to replace the molecular sieve inside the filter box 501, making the filtering effect of nitrous oxide more stable;

[0045] The filtering and condensing mechanism 5 further includes an electromagnet 504 fixedly connected to one end of the connecting pipe 503. A permanent magnet 505 is magnetically attracted to the surface of the electromagnet 504. Through the mutual cooperation of the electromagnet 504 and the permanent magnet 505, when the spiral tube 507 needs to be cleaned and replaced, the electromagnet 504 is powered off, so that the electromagnet 504 no longer generates magnetic force, so that the electromagnet 504 and the permanent magnet 505 can be separated, and the ventilation pipe 506 can be disassembled, so that the spiral tube 507 and the components in the cooling mechanism 7 are separated from the bracket assembly 1, which is convenient for the staff to clean and replace the spiral tube 507. A ventilation pipe 506 communicated with the connecting pipe 503 is fixedly connected to the surface of the permanent magnet 505. Spiral tubes 507 communicated with the ventilation pipe 506 are fixedly connected to the surface of the ventilation pipe 506 in a path array. One ends of a plurality of spiral tubes 507 are commonly fixedly connected to a storage box 508. An extrusion mechanism 8 is installed inside the storage box 508. A cooling mechanism 7 is commonly installed on the surfaces of a plurality of ventilation pipes 506;

[0046] The electromagnet 504 and the permanent magnet 505 are fitted together, and the electromagnet 504 is powered on, so that the electromagnet 504 generates magnetic force, and the electromagnet 504 and the permanent magnet 505 are magnetically attracted, so that while the connecting pipe 503 and the ventilation pipe 506 are communicated, they are closely fitted, which can not only transport the nitrous oxide, but also avoid the leakage of nitrous oxide. Thus, through the setting of the ventilation pipe 506, the nitrous oxide enters the inside of the spiral tube 507.

[0047] The cooling mechanism 7 includes a number of sleeves 701 respectively fixedly sleeved on the surface of the spiral tube 507. A through pipe 702 is fixedly connected to the opposite sides of every two adjacent sleeves 701. A circulation pipe 703 is fixedly connected to the surface of one of the sleeves 701, and a circulation pipeline 704 is fixedly connected to the surface of another sleeve 701. A circulation pump 705 is fixedly connected to the surfaces of the circulation pipeline 704 and the circulation pipe 703. A support plate 706 is fixedly connected to the surface of the circulation pump 705. Through the arrangement of the support plate 706, the circulation pump 705 is more stable when in use;

[0048] Cooling water is injected into the sleeve 701. By starting the circulation pump 705, the cooling water circulates inside the circulation pipeline 704, the circulation pipe 703 and the through pipe 702, so that the cooling water absorbs heat from the surface of the spiral tube 507, making the nitrous oxide gas condense into a liquid inside the spiral tube 507, completing the production of nitrous oxide liquid, and making the produced nitrous oxide liquid enter the storage box 508 for storage. Through the setting of the cooling water circulation, after the cooling water leaves the sleeve 701, it is cooled by the external air, so that the cooling water maintains the heat absorption effect and makes the temperature of the surface of the spiral tube 507 more stable.

[0049] The extrusion mechanism 8 includes a sealing plate 801 slidably connected inside the storage box 508. A threaded rod 802 is threadedly inserted into the surface of the sealing plate 801. One end of the threaded rod 802 penetrates through one side of the storage box 508 and is fixedly connected to a drive motor 803 fixedly connected to the support plate 706. A detection pipe 804 is fixedly connected to the surface of the storage box 508. A discharge pipe 805 corresponding to an external existing steel cylinder is fixedly connected to one side of the surface of the storage box 508.

[0050] Through the setting of the detection pipe 804, a sample of the nitrous oxide liquid inside the storage box 508 is taken, which facilitates the staff to detect the produced nitrous oxide. When the detection result meets the standard, place the steel cylinder under the discharge pipe 805, open the water valve on the surface of the discharge pipe 805, and start the drive motor 803, so that its output end drives the threaded rod 802 to rotate inside the storage box 508, driving the sealing plate 801 to slide inside the storage box 508, changing the air pressure inside the storage box 508, thereby squeezing the nitrous oxide liquid inside the storage box 508 to be injected into the steel cylinder through the discharge pipe 805 for packaging the nitrous oxide liquid, thus avoiding the remaining nitrous oxide liquid inside the storage box 508. Example Three:

[0051] The difference between this embodiment and the second embodiment is that the bracket assembly 1 includes a support frame 101. On both sides of the lower surface of the support frame 101, mounting plates 102 are fixedly connected. The support plate 706 is slidably inserted into one of the mounting plates 102. The bearing plate 502 is fixedly connected to the opposite sides of the two mounting plates 102. The primary caustic washing cylinder 301, the secondary caustic washing cylinder 303, the water washing cylinder 201 and the re-washing cylinder 401 are all fixedly connected to the support frame 101;

[0052] The discharging mechanism 6 is fixedly connected to the water outlet pipe 601 communicating with the two drain pipes 306. The sewage discharge pipe 402 and the sewage pipe 205 are both connected to the water outlet pipe 601. At one end of the two water outlet pipes 601, water pumps 602 are fixedly connected. A sewage main pipe 603 is fixedly connected to the surfaces of the two water outlet pipes 601. A water valve is installed on the surface of the sewage main pipe 603. By starting the water pumps 602, the sewage discharged from the sewage discharge pipe 402, the drain pipes 306 and the sewage pipe 205 is injected into the interior of the water outlet pipe 601, so that the sewage is discharged through the sewage main pipe 603, completing the discharge of the sewage.

[0053] Working principle: The ammonium nitrate solution is added with diammonium hydrogen phosphate through the melting pot and reacts with the reactor to obtain the crude nitrous oxide gas. The crude nitrous oxide gas is transported to the interior of one of the water washing cylinders 201 through the air guide pipe 207. By opening the valve 203, the drinking water enters the interior of the water washing cylinder 201 through the water inlet pipe 202, and the crude nitrous oxide gas is subjected to primary water washing. Through the setting of the air inlet pipe 204, the crude nitrous oxide gas after primary water washing enters the interior of another water washing cylinder 201 for secondary water washing;

[0054] The nitrous oxide after two water washings enters the interior of the primary caustic washing cylinder 301 through the diversion pipe 206. The sodium hydroxide, potassium permanganate solution and domestic drinking water are respectively transported to the interiors of the primary caustic washing cylinder 301 and the secondary caustic washing cylinder 303 through the caustic washing pipe 305. The nitrous oxide is subjected to caustic washing by the primary caustic washing cylinder 301, and the nitrous oxide after primary caustic washing is transported to the interior of the secondary caustic washing cylinder 303 through the connecting pipe 302 for secondary caustic washing of the nitrous oxide;

[0055] The nitrous oxide after secondary caustic washing is transported to the interior of the re-washing cylinder 401. The drinking water is injected into the interior of the re-washing cylinder 401 through the water delivery pipe, and the nitrous oxide is washed again. The nitrous oxide discharged through the hollow pipe 404 enters the interior of the filter box 501, and the nitrous oxide is filtered by the molecular sieve. The filtered nitrous oxide is discharged through the connecting pipe 503. Through the setting of the ventilation pipe 506, the nitrous oxide enters the interior of the spiral pipe 507;

[0056] Inject cooling water inside the sleeve 701. By starting the circulation pump 705, the cooling water circulates inside the circulation pipeline 704, the circulation pipe 703 and the through pipe 702, so that the cooling water absorbs heat from the surface of the spiral pipe 507, causing the nitrous oxide gas to condense into a liquid inside the spiral pipe 507, and causing the produced nitrous oxide liquid to enter the storage box 508 for storage;

[0057] Place the steel cylinder under the discharge pipe 805, open the water valve on the surface of the discharge pipe 805, and start the drive motor 803. Its output end drives the threaded rod 802 to rotate inside the storage box 508, driving the sealing plate 801 to slide inside the storage box 508, changing the air pressure inside the storage box 508, thereby squeezing the nitrous oxide liquid inside the storage box 508 to be injected into the steel cylinder through the discharge pipe 805 for encapsulating the nitrous oxide liquid;

[0058] Start the water pump 602 to inject the sewage discharged from the sewage discharge pipe 402, the drain pipe 306 and the sewage pipe 205 into the inside of the water discharge pipe 601, so that the sewage is discharged through the sewage main pipe 603 to complete the discharge of the sewage.
