Description

Technical Field

[0001] The invention belongs to the technical field of condensers for nitrous oxide production, in particular to a condenser for liquefaction of nitrous oxide production. Background Art

[0002] Nitrous oxide, also known as nitrous oxide, has the chemical formula Carbon monoxide (CO) is a colorless, odorless, and non-irritating gas. It is an oxidant, combustion aid, and anesthetic, primarily used in the medical, food additive, and electronics industries. Carbon monoxide, with its chemical formula of CO, is a colorless, odorless, and non-irritating gas that originates primarily from incomplete combustion. It is toxic and can have serious health consequences.

[0003] When nitrous oxide is produced, it is generally produced by condensation, which requires the use of a condenser for liquefaction of nitrous oxide production.

[0004] When some existing condensers for liquefaction of nitrous oxide production are used, a hydraulic rod is generally used to squeeze a piston downward, causing the liquefied nitrous oxide around it to move downward through a hanging ring, pushing the liquefied nitrous oxide on the inner wall of the liquefaction pipe downward and out through the liquid outlet pipe, thereby accelerating the downward flow of the liquefied nitrous oxide and avoiding the waste of liquefied nitrous oxide remaining on the inner wall of the liquefaction pipe due to uncollection, thereby increasing the output in the production process and saving raw materials.

[0005] However, when some existing condensers for liquefaction of nitrous oxide production are used, although the liquefied nitrous oxide on the inner wall of the liquefaction pipe is pushed out by a hydraulic rod, the crude nitrous oxide gas produced during the condensation of the nitrous oxide cannot be washed with water, and thus the impurities in the nitrous oxide in the crude gas cannot be removed. As a result, the nitrous oxide contains impurities after condensation, which reduces the purity of the nitrous oxide and thus reduces the quality of the nitrous oxide.

[0017] The beneficial effects of the present invention are as follows: 1. The condenser for nitrous oxide production and liquefaction of the present invention, through the arrangement of a water washing mechanism, an alkali washing mechanism, and a re-washing mechanism, conveys crude nitrous oxide gas to the interior of a water washing drum. By connecting the two water washing drums, the crude nitrous oxide gas is washed twice with water, and the used washing water is discharged through a sewage pipe. The nitrous oxide after the two water washings is conveyed to the interior of a primary alkali washing drum through a guide pipe. Sodium hydroxide, potassium permanganate solution, and drinking water are respectively conveyed to the interiors of the primary alkali washing drum and the secondary alkali washing drum through the alkali washing pipe.

After multiple water washings, the nitrous oxide enters the interior of the spiral tube through the connecting pipe. The cooling mechanism absorbs the heat of the spiral tube, thereby causing the nitrous oxide to condense into liquid inside the spiral tube. After the electromagnet is powered off, the electromagnet and the permanent magnet cooperate with each other, so that the cooling mechanism and the spiral tube and other components can be disassembled and cleaned, thereby making the filtration and condensation mechanism more convenient to disassemble and clean. 4. The condenser for liquefying nitrous oxide production described in the present invention, through the arrangement of structures such as an extrusion mechanism, stores the liquid nitrous oxide in a storage box after the nitrous oxide is condensed into liquid through the spiral tube, and the arrangement of the detection tube facilitates the staff to sample and detect the liquid nitrous oxide inside the storage box. When bottling the liquid nitrous oxide, the steel cylinder is placed below the discharge pipe, and the drive motor is started so that the threaded rod drives the sealing plate to move, thereby changing the air pressure inside the storage box, and squeezing the liquid nitrous oxide inside the storage box through the discharge pipe and loading it into the steel cylinder for packaging. Thus, by changing the air pressure, the liquefied nitrous oxide is avoided from remaining inside the storage box, which not only avoids the waste of nitrous oxide, but also prevents the residual nitrous oxide from affecting the quality of the next condensed and oxidized liquid nitrogen.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Reference Figure 1 - Figure 9 , the present invention provides three technical solutions: Example 1

[0023] A condenser for liquefaction of nitrous oxide production includes a support assembly 1, a water washing mechanism 2 is installed inside the support assembly 1, an alkali washing mechanism 3 is installed on the surface of the water washing mechanism 2, a re-washing mechanism 4 is installed on the surface of the alkali washing mechanism 3, a filtering and condensing mechanism 5 is installed on the surface of the re-washing mechanism 4, and a discharge mechanism 6 is installed on the surface of the filtering and condensing mechanism 5; The water washing mechanism 2 includes two water washing cylinders 201 respectively installed on both sides of the surface of the bracket assembly 1. One side of the surface of the two water washing cylinders 201 is fixedly connected to an air guide pipe 207 connected to an external existing reactor. The surface of one of the water washing cylinders 201 is fixedly connected to a guide pipe 206 connected to the secondary alkaline washing cylinder 303. One end of the two water washing cylinders 201 is fixedly connected to a water inlet pipe 202. Valves 203 are installed on both sides of the surface of the water inlet pipe 202. Through the setting of the valve 203, drinking water can enter the two water washing cylinders 201 respectively according to the switch of the valve 203. The water inlet pipe 202 is connected to the external existing water pipe. The upper surface of one of the water washing cylinders 201 is fixedly connected to an air inlet pipe 204 connected to the other water washing cylinder 201. The other ends of the two water washing cylinders 201 are fixedly connected to a sewage pipe 205 connected to the drain pipe 306.

[0024] Ammonium nitrate solution is added to diammonium hydrogen phosphate through a melting pot and reacted with a reactor to obtain 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, drinking water is allowed to enter the interior of the water washing cylinder 201 through the water inlet pipe 202 to wash the crude nitrous oxide gas once. The setting of the air inlet pipe 204 allows the crude nitrous oxide gas after the first water washing to enter the interior of another water washing cylinder 201 for a second water washing, so that the impurities reacting with water contained in the crude nitrous oxide gas are cleaned out of nitrous oxide. The used drinking water is discharged from the water washing cylinder 201 through the setting of the sewage pipe 205, which facilitates the subsequent continuous use of the water washing mechanism 2.

[0025] The alkali washing mechanism 3 includes a primary alkali washing cylinder 301 mounted on the surface of the water washing mechanism 2, a connecting pipe 302 is fixedly connected to the surface of the primary alkali washing cylinder 301, one end of the connecting pipe 302 is fixedly connected to a secondary alkali washing cylinder 303 connected to the primary alkali washing cylinder 301 through the connecting pipe 302, and one end of the primary alkali washing cylinder 301 and the secondary alkali washing cylinder 303 are fixedly connected to a three-way water pipe 304. Through the arrangement of the three-way water pipe 304, the alkali washing liquid can enter the interior of the primary alkali washing cylinder 301 and the secondary alkali washing cylinder 303. One end of the three-way water pipe 304 is fixedly connected to the primary alkali washing cylinder 301 and the secondary alkali washing cylinder 303. A caustic washing pipe 305 is connected to the primary caustic washing cylinder 301 and the secondary caustic washing cylinder 303 through a three-way water pipe 304. The other ends of the primary caustic washing cylinder 301 and the secondary caustic washing cylinder 303 are fixedly connected to a drain pipe 306. The lower surface of the secondary caustic washing cylinder 303 is fixedly connected to a discharge pipe 307 with a one-way valve inside. Due to the setting of the one-way valve, the nitrous oxide after the secondary caustic washing can only pass through the discharge pipe 307 and enter the interior of the secondary caustic washing cylinder 401 from the secondary caustic washing cylinder 303, and cannot enter the interior of the secondary caustic washing cylinder 303 through the second washing cylinder 401. The nitrous oxide that has been washed twice with water enters the first alkali washing cylinder 301 through the guide pipe 206, and the sodium hydroxide, potassium permanganate solution and drinking water are respectively transported to the first alkali washing cylinder 301 and the second alkali washing cylinder 303 through the alkali washing pipe 305. The nitrous oxide is alkali-washed by the first alkali washing cylinder 301, and the nitrous oxide that has been alkali-washed once is transported to the second alkali washing cylinder 303 through the connecting pipe 302, and the nitrous oxide is alkali-washed twice, thereby further cleaning the impurities in the nitrous oxide and purifying the nitrous oxide, thereby improving the quality of the nitrous oxide after production. The used alkali washing liquid is discharged from the first alkali washing cylinder 301 and the second alkali washing cylinder 303 through the setting of the drain pipe 306, which facilitates the alkali washing of the nitrous oxide again. The rewash mechanism 4 includes a rewash drum 401 fixedly connected to one end of the discharge pipe 307 and communicated with the discharge pipe 307, one end of the rewash drum 401 is fixedly connected to a sewage pipe 402 communicated with the drain pipe 306, the other end of the rewash drum 401 is fixedly connected to an air outlet pipe 403, a water supply pipe is installed on the surface of the rewash drum 401, and one end of the air outlet pipe 403 is fixedly connected to a hollow tube 404.

[0026] Through the setting of the discharge pipe 307, the nitrous oxide after the second alkali washing is transported to the interior of the re-washing drum 401, and drinking water is injected into the interior of the re-washing drum 401 through the water supply pipe to wash the nitrous oxide again, thereby making the nitrous oxide purer. The used drinking water is then discharged through the sewage pipe 402, and the washed nitrous oxide is discharged through the hollow tube 404. Example 2

[0027] 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, and both sides of the filter box 501 are respectively connected to the connecting pipe 503 and the hollow tube 404, and a sampling tube 509 connected to the filter box 501 is fixedly connected to the front of the filter box 501. The provision of the sampling tube 509 facilitates the staff to sample and detect the nitrous oxide gas inside the filter box 501, thereby facilitating the control of the quality of nitrous oxide production. The nitrous oxide discharged through the hollow tube 404 enters the interior of the filter box 501 and is filtered by the molecular sieve, thereby making the nitrous oxide more pure. The filtered nitrous oxide is then discharged through the connecting tube 503. The bolts are provided to allow the filter box 501 to be disassembled, thereby facilitating the replacement of the molecular sieve inside the filter box 501 by the staff, and making the nitrous oxide filtering effect more stable. The filtering and condensing mechanism 5 also includes an electromagnet 504 fixedly connected to one end of the connecting pipe 503. The surface of the electromagnet 504 is magnetically attracted by a permanent magnet 505. Through the cooperation between 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 is disassembled, so that the spiral tube 507 and the cooling mechanism 7 are separated. The parts are separated from the bracket assembly 1, which makes it convenient for the staff to clean and replace the spiral tube 507. The surface of the permanent magnet 505 is fixedly connected to the ventilation tube 506 connected to the connecting tube 503. The surface of the ventilation tube 506 is fixedly connected to the spiral tube 507 connected to the ventilation tube 506 in a path array. One end of the plurality of spiral tubes 507 is commonly fixedly connected to a storage box 508. The storage box 508 is internally installed with an extrusion mechanism 8. The surfaces of the plurality of ventilation tubes 506 are commonly installed with a cooling mechanism 7. The electromagnet 504 is fitted with the permanent magnet 505 and energized to generate magnetic force. This causes the electromagnet 504 to be magnetically attracted to the permanent magnet 505, thereby connecting the connecting tube 503 and the vent pipe 506 and fitting them tightly together. This not only allows for the transport of nitrous oxide but also prevents leakage of nitrous oxide. Thus, the vent pipe 506 allows the nitrous oxide to enter the interior of the spiral tube 507.

[0028] The cooling mechanism 7 includes a plurality of sleeves 701 fixedly sleeved on the surface of the spiral tube 507. The opposite sides of each two adjacent sleeves 701 are fixedly connected to a through pipe 702. A circulation pipe 703 is fixedly connected to the surface of one sleeve 701, and a circulation pipe 704 is fixedly connected to the surface of the other sleeve 701. The surfaces of the circulation pipe 704 and the circulation pipe 703 are fixedly connected to a circulation pump 705. The surface of the circulation pump 705 is fixedly connected to a support plate 706. The provision of the support plate 706 makes the circulation pump 705 more stable during use. Cooling water is injected into the sleeve 701, and the circulation pump 705 is started to circulate the cooling water in the circulation pipe 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, causing the nitrous oxide gas to condense into liquid inside the spiral tube 507, completing the production of nitrous oxide liquid, and allowing the produced nitrous oxide liquid to enter the storage box 508 for storage. Through the setting of the cooling water circulation, the cooling water is cooled by the external air after leaving the sleeve 701, so that the cooling water maintains the heat absorption effect, making the temperature of the surface of the spiral tube 507 more stable.

[0029] The extrusion mechanism 8 includes a sealing plate 801 that is slidably connected to the inside of the storage box 508, and a threaded rod 802 is threadedly inserted into the surface of the sealing plate 801. One end of the threaded rod 802 passes through one side of the storage box 508 and is fixedly connected to a drive motor 803 that is fixedly connected to the support plate 706. A detection tube 804 is fixedly connected to the surface of the storage box 508, and one side of the surface of the storage box 508 is fixedly connected to a discharge pipe 805 corresponding to the existing external cylinder.

[0030] By setting up the detection tube 804, the nitrous oxide liquid inside the storage box 508 is sampled, which makes it convenient for the staff to detect the produced nitrous oxide. When the test result meets the standard, the cylinder is placed under the discharge pipe 805, the water valve on the surface of the discharge pipe 805 is opened, and the drive motor 803 is started, 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 into the cylinder through the discharge pipe 805, and encapsulating the nitrous oxide liquid, thereby avoiding residual nitrous oxide liquid inside the storage box 508. Example 3

[0031] The difference between this embodiment and the second embodiment is that the bracket assembly 1 includes a support frame 101, and mounting plates 102 are fixedly connected to both sides of the lower surface of the support frame 101. The support plate 706 is slidably plugged into one of the mounting plates 102, and the bearing plate 502 is fixedly connected to the opposite sides of the two mounting plates 102. The primary alkali washing cylinder 301, the secondary alkali washing cylinder 303, the water washing cylinder 201 and the re-washing cylinder 401 are all fixedly connected to the support frame 101; The discharge mechanism 6 is fixedly connected to the outlet pipe 601 connected to the two drain pipes 306. The sewage pipe 402 and the sewage pipe 205 are both connected to the outlet pipe 601. One end of the two outlet pipes 601 is fixedly connected to a water pump 602. The surfaces of the two outlet pipes 601 are commonly fixedly connected to a sewage main pipe 603. A water valve is installed on the surface of the sewage main pipe 603. By starting the water pump 602, the sewage discharged from the sewage pipe 402, the drain pipe 306 and the sewage pipe 205 is injected into the interior of the outlet pipe 601, so that the sewage is discharged through the sewage main pipe 603, completing the discharge of sewage.

[0032] Working principle: Ammonium nitrate solution is added to diammonium hydrogen phosphate through a melting pot and reacted with a reactor to produce crude nitrous oxide gas. The crude nitrous oxide gas is transported to the interior of one of the water washing cylinders 201 through an air guide pipe 207. By opening valve 203, drinking water is allowed to enter the interior of the water washing cylinder 201 through the water inlet pipe 202 to perform a primary water washing on the crude nitrous oxide gas. The setting of the air inlet pipe 204 allows the crude nitrous oxide gas after the primary water washing to enter the interior of the other water washing cylinder 201 for a secondary water washing. The nitrous oxide that has been washed twice with water enters the first alkali washing cylinder 301 through the flow guide pipe 206. Sodium hydroxide, potassium permanganate solution, and drinking water are transported to the first alkali washing cylinder 301 and the second alkali washing cylinder 303 through the alkali washing pipe 305, respectively. The nitrous oxide is alkali-washed in the first alkali washing cylinder 301, and the nitrous oxide from the first alkali washing is transported to the second alkali washing cylinder 303 through the connecting pipe 302 for a second alkali washing of the nitrous oxide. The nitrous oxide after the secondary alkali washing is transported to the interior of the rewashing drum 401. Drinking water is injected into the rewashing drum 401 through the water pipe to wash the nitrous oxide again. The nitrous oxide discharged through the hollow tube 404 enters the interior of the filter box 501 and is filtered through the molecular sieve. The filtered nitrous oxide is discharged through the connecting tube 503 and enters the interior of the spiral tube 507 through the arrangement of the vent pipe 506. Cooling water is injected into the sleeve 701. By starting the circulation pump 705, the cooling water circulates in the circulation pipe 704, the circulation pipe 703, and the through pipe 702. As a result, the cooling water absorbs heat from the surface of the spiral tube 507, causing the nitrous oxide gas to condense into liquid inside the spiral tube 507. The produced nitrous oxide liquid is then stored in the storage box 508. 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 into the steel cylinder through the discharge pipe 805, thereby encapsulating the nitrous oxide liquid; Start the water pump 602 to inject the sewage discharged from the sewage pipe 402, the drainage pipe 306 and the sewage pipe 205 into the outlet pipe 601, so that the sewage is discharged through the sewage main pipe 603, completing the discharge of sewage.
