Description

Technical Field

[0001] This utility model relates to the field of nitrogen treatment technology, specifically to a high-efficiency nitrogen drying and dehydration device. Background Technology

[0002] In modern industrial production and scientific research, nitrogen is widely used in industries such as chemical, electronics, food, medicine, and metallurgy due to its stable chemical properties and resistance to reaction with other substances.

[0003] The prior art discloses a high-efficiency drying and dehydration device with announcement number CN221924460U, which includes a shell with a feed inlet at the top and a discharge outlet at the bottom. Multiple sets of electric heating plates are arranged inside the shell, and the multiple sets of electric heating plates are arranged at intervals along the direction from the feed inlet to the discharge outlet. The multiple sets of electric heating plates are interleaved to form a baffle channel. Multiple sets of crushing components connected to the electric heating plates are also arranged inside the shell. The crushing components crush the material on the electric heating plates. A drive component connected to the multiple sets of crushing components is arranged on the shell.

[0004] The aforementioned high-efficiency nitrogen drying and dehydration device drives multiple sets of crushing components through a drive assembly. Agglomerated materials are crushed by these components, making them easier to dry and dehydrate. This effectively avoids the problem of material agglomeration reducing the drying and dehydration effect. However, the device does not have an inclined molecular sieve, resulting in a short contact time between nitrogen and the internal sieve components, low dehydration efficiency, and poor performance during use. Improvements are needed in this regard. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency nitrogen drying and dehydration device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency nitrogen drying and dehydration device, comprising a dehydration cylindrical tower, a connecting pipe fitting at the top of the dehydration cylindrical tower, a connecting tower body at the bottom of the connecting pipe fitting, a condensate discharge assembly on the right side of the dehydration cylindrical tower, and a molecular sieving assembly inside the dehydration cylindrical tower.

[0007] The molecular sieving assembly includes a molecular sieve plate, a connecting disk, a connecting permeable plate, a first staggered molecular sieve element, a middle connecting plate, and a second staggered molecular sieve element.

[0008] Preferably, the condensate discharge assembly includes a discharge box, a connecting frame plate, a sealing baffle, a discharge box, a blocking sieve plate, a magnetic suction plate, and a magnetic strip. The discharge box is fixedly connected to the right side of the dehydration tower, the connecting frame plate is fixedly connected to the top of the discharge box, the sealing baffle plate is connected to the bottom of the discharge box, the discharge box is fixedly connected to the right side of the discharge box, the magnetic suction plate is fixedly connected to the front of the discharge box, the blocking sieve plate is connected to the right side of the discharge box, the magnetic strip is fixedly connected to the surface of the blocking sieve plate, and the magnetic strip is connected to the top of the magnetic suction plate.

[0009] Preferably, the inner ring of the dehydration column is provided with a flow guide groove, which is distributed in a ring at equal intervals in the inner ring of the dehydration column.

[0010] Preferably, the discharge box has a discharge groove inside, and the length of the discharge groove is adapted to the length of the sealing baffle, so that when drainage is not required, the sealing baffle forms a barrier to prevent condensate from flowing out suddenly and affecting subsequent processing.

[0011] Preferably, the sealed baffle is slidably connected to the inside of the connecting frame plate, and the inner surface of the connecting frame plate is adapted to the bottom area of ​​the sealed baffle.

[0012] Preferably, the magnetic strip is magnetically connected to the magnetic plate, and a blocking screen is installed on the right side of the discharge box using the magnetic connection between the magnetic plate and the magnetic strip, so that the condensate can be filtered when discharged, reducing impurities and odors, and facilitating subsequent processing.

[0013] Preferably, the first interlaced molecular sieve element and the second interlaced molecular sieve element are of the same type.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This high-efficiency nitrogen drying and dehydration device incorporates a molecular sieve assembly. The internal molecular sieve has an inclined angle, and the nitrogen changes its flow direction multiple times as it passes through the packing layer, increasing the contact time and contact area with the molecular sieve. As the nitrogen rises, it continuously and fully contacts the molecular sieve in different directions, thus removing moisture more efficiently and achieving good results in use.

[0016] This high-efficiency nitrogen drying and dehydration device is equipped with a condensate discharge component. During use, the internal condensate is discharged through the discharge box. When discharge is needed, the sealed baffle can be pulled out from inside the connecting frame plate to open the channel for normal condensate discharge. An outlet box is set on the right side, and a blocking screen plate is installed on the right side of the outlet box using magnetic attraction plate and magnetic strip. This allows the condensate to be filtered during discharge, reducing impurities and odors, and facilitating subsequent processing. Attached Figure Description

[0027] The condensate discharge assembly 4 includes a discharge box 401, a connecting frame plate 402, a sealing baffle 403, a discharge box 404, a blocking screen plate 405, a magnetic suction plate 406, and a magnetic strip 407. The discharge box 401 is fixedly connected to the right side of the dehydration tower 1. The connecting frame plate 402 is fixedly connected to the top of the discharge box 401. The sealing baffle 403 is connected to the bottom of the discharge box 401. The discharge box 404 is fixedly connected to the right side of the discharge box 401.

The interior of 01 has a discharge trough, the length of which is adapted to the length of the sealed baffle 403. When drainage is not required, the sealed baffle 403 forms a barrier to prevent condensate from suddenly flowing out and affecting subsequent processing.

The molecular sieves used are 4A or 5A models, possessing good water absorption and chemical stability. During setup, the first staggered molecular sieve assembly 504 and the second staggered molecular sieve assembly 506 are arranged at a certain angle. As the nitrogen gas passes through the packing layers, its flow direction changes multiple times, increasing the contact time and contact area with the molecular sieves.

The system is effective, and a condensate discharge assembly 4 is provided on the right side of the dehydration tower 1. During use, the internal condensate is discharged using the discharge box 401.
