Description

Technical Field

[0001] This utility model relates to the field of nitrogen air separation technology, and in particular to a high-efficiency nitrogen air separator. Background Technology

[0002] A nitrogen air separator is a device used to separate nitrogen from other components of air to produce nitrogen and other gases. The main methods for separating air are cryogenic distillation and compression cycle deep freezing. The equipment is widely used in traditional coal chemical industry, large-scale nitrogen fertilizer, gas supply and other fields.

[0003] When an air separator separates gases, a portion of the air is sent to the upper part of the distillation column, while the other portion, after being cooled, is sent to the lower column. After being processed inside the distillation column, the rising vapor and the falling liquid exchange heat to produce nitrogen and oxygen. However, the gas has not undergone corresponding purification treatment before entering the distillation column. Although nitrogen can be obtained, it contains some particulate matter and a small amount of irritating gas generated in the upstream processing steps, which will affect the purity of the nitrogen. Therefore, a high-efficiency nitrogen air separator is needed to meet the application requirements. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency nitrogen air separator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency nitrogen air separator, comprising a base, a distillation column disposed on the base, an upper inlet pipe and a lower inlet pipe disposed on the distillation column, a support column fixedly installed on the base, a disassembly sleeve fixedly installed on the support column, a purification box disposed inside the disassembly sleeve, a coarse filter, a fine filter and an activated carbon purification layer disposed inside the purification box, a through pipe fixedly installed at both the inlet and outlet ends of the disassembly sleeve, an insert pipe disposed inside the through pipe, a flexible hose fixedly installed at the end of a set of insert pipes, a connector disposed on both the upper inlet pipe and the lower inlet pipe, and the other end of a set of flexible hoses respectively fixedly disposed in the connector.

[0006] Preferably, an elastic locking step is fixedly installed on the insertion tube, and a locking block is fixedly installed on the through tube, with the locking block engaging within the elastic locking step.

[0007] Preferably, an L-shaped insert rod is fixedly installed on the insertion tube, a sleeve is fixedly installed on the through tube, a compression spring is fixedly installed inside the sleeve, and the L-shaped insert rod is inserted into the sleeve.

[0008] Preferably, a sealing sleeve is fixedly installed inside the through pipe, and a sealing strip is fixedly installed inside the disassembly sleeve.

[0009] Preferably, a support block is fixedly installed on the disassembly sleeve, and a retaining block is rotatably installed on the support block, with the retaining block abutting against the purification box.

[0010] Preferably, torsion springs are fixedly installed on the support block and the retaining block, and a pull sleeve is fixedly installed on the purification box.

[0011] Preferably, there is one set of the disassembly sleeves, and a connecting plate is fixedly installed on one set of the disassembly sleeves.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, through the arrangement of a tube, a coarse filter, a fine filter, an activated carbon purification layer, and a purification chamber, external gas enters the purification chamber through the tube and undergoes coarse filtration through the coarse filter to remove larger particulate matter. The gas then passes through the fine filter for further filtration to remove smaller particulate matter. Finally, the activated carbon purification layer adsorbs irritating odors from the gas, resulting in relatively pure nitrogen gas obtained from the distillation column and high air separation efficiency.

[0014] In this invention, by setting up structures such as elastic locking step, locking block, fixing block, and pull sleeve, the elastic locking step is moved on the locking block so that the elastic locking step is no longer locked with the locking block. At this time, under the action of the compression spring, the insertion tube will be driven to pop out from the through tube, thereby separating the end of the insertion tube from the purification box. Then, the fixing block is rotated and the fixing block and the purification box are misaligned. The pull sleeve is then pulled to pull the purification box out from the disassembly sleeve, which can facilitate the replacement of the coarse filter, fine filter and activated carbon purification layer, and ensure the filtration effect of air separation gas.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example:

[0022] like Figure 1-4 As shown, this embodiment provides a high-efficiency nitrogen air separator, including a base 1, a distillation column 2 on the base 1, an upper inlet pipe 3 and a lower inlet pipe 4 on the distillation column 2, a support column 5 fixedly installed on the base 1, a disassembly sleeve 6 fixedly installed on the support column 5, a purification box 7 inside the disassembly sleeve 6, a coarse filter 8, a fine filter 9 and an activated carbon purification layer 10 inside the purification box 7, a through pipe 11 fixedly installed at both the inlet and outlet ends of the disassembly sleeve 6, an insert pipe 12 inside the through pipe 11, a flexible hose 13 fixedly installed at the end of a set of insert pipes 12, a connector 14 on both the upper inlet pipe 3 and the lower inlet pipe 4, and the other end of a set of flexible hoses 13 fixedly installed in the connector 14 respectively;

[0023] The external air intake pipes are connected to the insertion tube 12, and the upper air intake pipe 3 and the lower air intake pipe 4 are connected to the hose 13 via connector 14. External gas enters the purification chamber 7 through the insertion tube 12 and is coarsely filtered by the coarse filter 8 to remove larger particulate matter. The coarsely filtered gas then passes through the fine filter 9 for fine filtration to remove smaller particulate matter. Finally, the gas passes through the activated carbon purification layer 10 to adsorb irritating odors, thus achieving air separation. The filtered gas then enters the hose 13 through the insertion tube 12 at the other end, and then enters the upper air intake pipe 3 and the lower air intake pipe 4 through a set of hoses 13. Finally, the gas enters the distillation column 2 through the upper air intake pipe 3 and the lower air intake pipe 4 for air separation, thus obtaining relatively pure nitrogen gas with good air separation efficiency.

[0024] Furthermore, an elastic locking step 15 is fixedly installed on the insertion tube 12, and a locking block 16 is fixedly installed on the through tube 11, with the locking block 16 locking into the elastic locking step 15; an L-shaped insertion rod 17 is fixedly installed on the insertion tube 12, and a sleeve 18 is fixedly installed on the through tube 11, with a compression spring 19 fixedly installed inside the sleeve 18, and the L-shaped insertion rod 17 inserted into the sleeve 18;

[0025] To facilitate the installation and removal of the insertion tube 12, the elastic locking step 15 is moved on the locking block 16, causing it to disengage from the locking block 16. At this point, the compression spring 19 causes the insertion tube 12 to pop out of the through-tube 11, thus completing the removal of the insertion tube 12. The L-shaped insertion rod 17 is aligned with the insertion sleeve 18, and the insertion tube 12 is inserted into the through-tube 11. The elastic locking step 15 will then be inserted into the locking block 16. The elastic locking step 15 will be pushed outwards by the pressure from the end of the locking block 16. When the locking holes on the locking block 16 and the elastic locking step 15 coincide, the elastic locking step 15 will lock onto the locking block 16 under the action of restoring its deformation, thus securing the insertion tube 12.

[0026] Furthermore, a sealing sleeve 20 is fixedly installed inside the through pipe 11, and a sealing strip 21 is fixedly installed inside the disassembly sleeve 6;

[0027] To ensure a seal at the connection points, the sealing sleeve 20 seals the connection between the through pipe 11 and the insertion pipe 12, while the sealing strip 21 seals the connection between the disassembly sleeve 6 and the purification box 7.

[0028] Furthermore, a support block 22 is fixedly installed on the disassembly sleeve 6, and a retaining block 23 is rotatably installed on the support block 22. The retaining block 23 abuts against the purification box 7, and a pull sleeve 25 is fixedly installed on the purification box 7.

[0029] To facilitate the replacement of the coarse filter 8, fine filter 9, and activated carbon purification layer 10, after prolonged use, the elastic locking step 15 on the locking block 16 is moved to disengage it from the locking block 16. At this point, the compression spring 19 causes the insertion tube 12 to pop out from the through-tube 11, separating the end of the insertion tube 12 from the purification box 7. Then, the retaining block 23 is rotated to offset itself from the purification box 7, and the pull sleeve 25 is pulled to remove the purification box 7 from the disassembly sleeve 6. This allows for easy replacement of the coarse filter 8, fine filter 9, and activated carbon purification layer 10, ensuring effective filtration of the air separation gas. Inserting the purification box 7 into the disassembly sleeve 6 causes the retaining block 23 to rotate and reset under the action of the torsion spring 24, securing the replaced purification box 7 within the disassembly sleeve 6.

[0030] Furthermore, torsion springs 24 are fixedly installed on the support block 22 and the retaining block 23;

[0031] To secure the purification box 7, insert the purification box 7 into the disassembly sleeve 6. Under the action of the torsion spring 24, the retaining block 23 will rotate and reset, pressing against the purification box 7, thus fixing the replaced purification box 7 inside the disassembly sleeve 6.

[0032] Working principle: In use, the external air intake pipe is connected to the insertion tube 12, and the upper air intake pipe 3 and the lower air intake pipe 4 are connected to the hose 13 through the connector 14. The external gas will enter the purification box 7 through the insertion tube 12 and pass through the coarse filter 8 to remove larger particulate matter. The gas after coarse filtration will pass through the fine filter 9 for fine filtration to remove smaller particulate matter. Finally, the gas will pass through the activated carbon purification layer 10 to adsorb irritating odor substances in the gas, thus achieving the function of air separation. The filtered gas will enter the hose 13 through the insertion tube 12 at the other end, and then enter the upper air intake pipe 3 and the lower air intake pipe 4 through a set of hoses 13. Finally, it will enter the distillation column 2 for air separation, thus obtaining relatively pure nitrogen gas with high air separation efficiency. After prolonged use, the elastic locking step 15 is moved on the locking block 16, so that the elastic locking step 15 is no longer locked with the locking block 16. At this time, under the action of the compression spring 19, the insertion tube 12 will be ejected from the through tube 11, thereby separating the end of the insertion tube 12 from the purification box 7. Then, the retaining block 23 is rotated and the retaining block 23 is offset from the purification box 7. The pull sleeve 25 is pulled to remove the purification box 7 from the disassembly sleeve 6, which can facilitate the replacement of the coarse filter 8, fine filter 9 and activated carbon purification layer 10, ensuring the filtration effect of air separation gas. Insert the purification box 7 into the disassembly sleeve 6. Under the action of the torsion spring 24, the retaining block 23 will rotate and reset, pressing against the purification box 7. The replaced purification box 7 can be fixed in the disassembly sleeve 6. Then, align the L-shaped insertion rod 17 with the insertion sleeve 18 and insert the insertion tube 12 into the through pipe 11. At this time, the elastic locking step 15 will also be inserted into the locking block 16. The elastic locking step 15 will be squeezed outward by the end of the locking block 16. When the locking hole on the locking block 16 and the elastic locking step 15 coincide, the elastic locking step 15 will be locked onto the locking block 16 under the action of restoring its deformation. At this time, the insertion tube 12 can be fixed. Install the other set of insertion tubes 12 in the same way to the air outlet of the disassembly sleeve 6. Then, connect a set of hoses 13 to the upper air inlet pipe 3 and the lower air inlet pipe 4 respectively through a set of connectors 14.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
