Description

Technical Field

[0001] This utility model relates to the technical field of gas drying, and more specifically, to a dual-cylinder dehumidifier. Background Technology

[0002] Molecular sieves possess advantages unmatched by other adsorbents, such as high adsorption capacity and strong thermal stability, leading to their widespread application in gas drying. However, after repeated use, molecular sieves become saturated with moisture, reducing drying efficiency. To minimize waste from frequent replacements, used molecular sieves are currently regenerated for reuse. However, molecular sieves are not infinitely regenerable; their regeneration cycle and lifespan are influenced by various factors, and they must be replaced with new ones once their lifespan is reached.

[0003] For example, Chinese utility model patent CN221788740U discloses a molecular sieve regeneration device. It has a molecular sieve filling port at the top of the drying tank and a molecular sieve discharge port at the bottom. The openings are small, resulting in a long filling time. This design is only suitable for replacing granular molecular sieves. If the drying tank is filled with honeycomb molecular sieves, since the honeycomb molecular sieves are blocky, they cannot be removed from the small discharge port. Therefore, it is necessary to disassemble the end caps at both ends of the drying tank. However, the end caps are connected to inlet pipes, outlet pipes, pressure sensors, etc., making disassembly quite troublesome. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model provides a dual-cylinder dehumidifier to solve the problems in the existing technology.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dual-cylinder dehumidifier, including a first dehumidifier cylinder and a second dehumidifier cylinder. Both the first dehumidifier cylinder and the second dehumidifier cylinder include a cylinder body. The cylinder body is filled with honeycomb molecular sieve. End caps are detachably installed at both ends of the cylinder body. The first dehumidifier cylinder and the second dehumidifier cylinder are connected to each other through a first air inlet and a second air inlet, respectively. One end of the upper side of the first dehumidifier cylinder and the second dehumidifier cylinder are connected through a first air outlet, and the other end is connected through a second air outlet, so that the first dehumidifier cylinder and the second dehumidifier cylinder form an independent switching gas flow path.

[0006] In the aforementioned dual-cylinder dehumidifier, the first air inlet includes a first three-way solenoid valve, and the second air inlet includes a second three-way solenoid valve.

[0007] In the aforementioned dual-cylinder dehumidifier, the first air outlet includes a first connecting portion located at one upper end of the first dehumidifier cylinder and a second connecting portion located at one upper end of the second dehumidifier cylinder.

[0009] In the aforementioned dual-cylinder dehumidifier, flanges are fixedly connected to both ends of the cylinder, the end cover is a flange sealing plate, and a flange gasket is provided between the flange and the flange sealing plate.

Filter cotton is provided inside the first ports of the first and second three-way solenoid valves.

[0011] The beneficial effects of this utility model are that the end caps at both ends of the dehumidification cylinder are detachable and no pipes are connected to the end caps.

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] Combination Figures 1 to 2 The illustrated dual-cylinder dehumidifier includes a first dehumidifier cylinder 10 and a second dehumidifier cylinder 20. Both the first dehumidifier cylinder 10 and the second dehumidifier cylinder 20 include a cylinder body 101, which is filled with a honeycomb molecular sieve 102. End caps 103 are detachably installed at both ends of the cylinder body 101. The first dehumidifier cylinder 10 and the second dehumidifier cylinder 20 are connected to each other through a first air inlet and a second air inlet, respectively. One end of the upper side of the first dehumidifier cylinder 10 and the second dehumidifier cylinder 20 is connected through a first air outlet, and the other end is connected through a second air outlet, so that the first dehumidifier cylinder 10 and the second dehumidifier cylinder 20 form an independent switching gas flow path. The end caps at both ends of the dehumidifier cylinder are detachable, and no pipes are connected to the end caps. When the molecular sieve in the dehumidifier cylinder reaches the regeneration cycle or service life, the end cap can be directly removed to take out the molecular sieve in the cylinder. The honeycomb molecular sieve filled in the cylinder is a whole, which is convenient for replacement and makes the operation simpler and more convenient.

[0017] Preferably, the first air intake section of this embodiment includes a first three-way solenoid valve 30, and the second air intake section includes a second three-way solenoid valve 40; the solenoid valve has the advantages of high safety, simple system, and fast action, which makes the entire dehumidification system more efficient.

[0018] It is worth noting that the first air outlet in this embodiment includes a first connecting part 50 located at one end of the upper side of the first dehumidifying cylinder 10 and a second connecting part 60 located at one end of the upper side of the second dehumidifying cylinder 20. The second air outlet includes a third connecting part 70 located at the other end of the upper side of the first dehumidifying cylinder 10 and a fourth connecting part 80 located at the other end of the upper side of the second dehumidifying cylinder 20. A first gas pipe 90 is connected between the first connecting part 50 and the second connecting part 60. A first air outlet 100 is provided in the middle of the first gas pipe 90. A second gas pipe 110 is connected between the third connecting part 70 and the fourth connecting part 80. A second air outlet 120 is provided in the middle of the second gas pipe 110. Each connecting part can control the gas flow path independently, and the structure is simple.

[0019] In this embodiment, the first connecting part 50, the second connecting part 60, the third connecting part 70, and the fourth connecting part 80 are two-way solenoid valves. Solenoid valves have the advantages of high safety, simple system, and fast action, which makes the entire dehumidification system more efficient.

[0020] Specifically, in this embodiment, flanges 104 are fixedly connected to both ends of the cylinder 101, and the end cover 103 is a flange sealing plate. A flange gasket 105 is provided between the flange 104 and the flange sealing plate. The flange structure can make the cylinder more airtight and prevent gas leakage.

[0021] Preferably, in this embodiment, the first port of the first three-way solenoid valve 30 is connected to the humid gas that needs to be dried, and the first port of the second three-way solenoid valve 40 is connected to the heated regeneration gas. Filter cotton is provided in the first port of the first three-way solenoid valve 30 and the first port of the second three-way solenoid valve 40. The filter cotton can filter out impurities in the gas before the gas enters the dehumidification cylinder, thereby improving the dehumidification efficiency.

[0022] The working principle of this utility model is as follows: In use, the first port of the first three-way solenoid valve 30 connected to the humid gas is opened, the second port of the first three-way solenoid valve 30 connected to the first dehumidification cylinder 10 is opened, and the third port of the first three-way solenoid valve 30 connected to the second dehumidification cylinder 20 is closed. At the same time, the port of the first connecting part 50 connected to the first dehumidification cylinder 10 is closed. In this way, the humid gas enters the first dehumidification cylinder 10 entirely through the first port of the first three-way solenoid valve 30. At the same time, the second port of the second three-way solenoid valve 40 connected to the first dehumidification cylinder 10 is closed, and the port of the third connecting part 70 connected to the first dehumidification cylinder 10 is opened. In this way, the humid gas is dried by the honeycomb molecular sieve 102 in the first dehumidification cylinder 10, and becomes dry gas. It then enters the second gas pipe 110 through the third connecting part 70. At the same time, the port of the fourth connecting part 80 connected to the second gas pipe 110 is closed, so the dry gas does not enter the second dehumidification cylinder 20 but is directly discharged from the second outlet 120.

[0023] While the first dehumidifier cylinder 10 is drying, the second dehumidifier cylinder 20 is regenerating the molecular sieve. During operation, the first port of the second three-way solenoid valve 40, which connects to the heated regeneration gas, is opened; the third port of the second three-way solenoid valve 40, which connects to the second dehumidifier cylinder 20, is opened; and the second port of the second three-way solenoid valve 40, which connects to the first dehumidifier cylinder 10, is closed. Simultaneously, the port of the fourth connecting part 80, which connects to the second dehumidifier cylinder 20, is closed. The regeneration gas enters the second dehumidifier cylinder 20 entirely through the first port of the second three-way solenoid valve 40. At the same time, the third port of the first three-way solenoid valve 30, which connects to the second dehumidifier cylinder 20, is closed; and the port of the second connecting part 60, which connects to the second dehumidifier cylinder 20, is opened. Thus, after regenerating the molecular sieve within the second dehumidifier cylinder 20, the regeneration gas passes through the second connecting part 60 and then enters the first gas pipe 90. Simultaneously, the port of the first connecting part 50, which connects to the first gas pipe 90, is closed, preventing the regeneration gas from entering the first dehumidifier cylinder 10 and allowing it to exit directly from the first outlet 100.

[0024] The two processes described above are performed simultaneously. After the above work is completed, the molecular sieve in the first dehumidification cylinder 10 is regenerated, and the gas in the second dehumidification cylinder 20 is dried. This process is repeated alternately, completing the drying of the gas while maintaining the continuous regeneration and reuse of the molecular sieve.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
