Description

Technical Field

[0001] This utility model relates to the field of nitrogen generator technology, specifically an energy-saving modular nitrogen generator. Background Technology

[0002] PSA (Prepared Air Separation) nitrogen generators are devices that use air as raw material and separate oxygen and nitrogen using physical methods to obtain high-purity nitrogen. They have advantages such as simple process flow, high degree of automation, low energy consumption, and high product purity, and are widely used in the field of industrial nitrogen production.

[0003] Existing nitrogen generators have complex structures for their various functional parts. The components used for nitrogen generation and the gas-electric control components are distributed in different locations within the machine, occupying a large area and causing difficulties in installation and storage. Furthermore, the unreasonable distribution of the nitrogen generation and gas-electric control components within the machine complicates maintenance and operation. In addition, existing nitrogen generators generally require manual start-up and shutdown control, which may result in idling during non-working periods. Moreover, both the nitrogen generation rate and the nitrogen generation time require manual adjustment; otherwise, excessive nitrogen generation may occur, leading to unnecessary waste of resources. Utility Model Content

[0004] To address the technical deficiencies in the background technology, this utility model proposes an energy-saving modular nitrogen generator, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0022] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples:

[0023] This utility model discloses an energy-saving modular nitrogen generator, such as Figures 1-4 As shown, the system includes a chassis 1, a nitrogen generator assembly 2, and an air handling assembly 3. The internal space of the chassis 1 is divided into a first chamber 12 and a second chamber 13 by a partition 11. The nitrogen generator assembly 2 includes a control box 21 and several adsorption towers 22. The control box 21 and several adsorption towers 22 are all disposed in a frame 23 and fixedly connected to the bottom of one side of the first chamber 12 by the frame 23. The air handling assembly 3 includes a cooler 31, a filter 32, and a dryer 33. The cooler 31, filter 32, and dryer 33 are all disposed in a housing 34 and fixedly connected to the top of one side of the first chamber 12 by the housing 34. The cooler 31, filter 32, dryer 33, and adsorption towers 22 are connected in sequence by pipes. An electrical control assembly 4 is provided in one side of the second chamber 13, and a frequency converter 5 is provided in the other side of the second chamber 13. The electrical control assembly 4 is electrically connected to the frequency converter 5, the nitrogen generator assembly 2, and the air handling assembly 3, respectively.

[0024] It should be noted that the nitrogen generator assembly 2 has several adsorption towers 22, and the operation of each adsorption tower 22 is controlled by the control box 21. Compressed air is transmitted through pipes connected to the air handling assembly 3 via pipe interfaces on the side wall of the casing 1. When the compressed air enters the module nitrogen generator, it first passes through the cooler 31 for cooling. After the temperature is reduced, it enters the filter 32 to purify and filter out oil content and mechanical impurities. The compressed air then enters the dryer 33, where more moisture is separated to meet the requirements of the carbon molecular sieve for compressed air operating conditions, resulting in clean and dry compressed air. This clean and dry compressed air enters from the bottom. As the compressed air flows through the carbon molecular sieve in adsorption tower 22 towards the upper outlet, oxygen in the compressed air is adsorbed, resulting in enriched nitrogen product that automatically flows out from the upper outlet of adsorption tower 22. After a period of adsorption, the carbon molecular sieve in one of the adsorption towers 22 reaches saturation. At this point, adsorption tower 22 automatically stops adsorption under the control of control box 21, and compressed air automatically flows into another adsorption tower 22 for adsorption. The nitrogen production process is the same as that of the previous adsorption tower 22, while simultaneously regenerating the carbon molecular sieve in the adsorption tower 22. Carbon molecular sieve regeneration is achieved by rapidly reducing the pressure inside the adsorption tower 22 to atmospheric pressure, at which point the adsorbed oxygen is rapidly discharged into the atmosphere. At least two adsorption towers 22 alternately operate for adsorption and regeneration, completing oxygen-nitrogen separation and continuously producing finished nitrogen product. The above-mentioned technique for producing nitrogen is highly efficient and has a low air consumption ratio. This technology is widely used in the field and is existing technology. Some components are not shown in the figures, and this should not affect the understanding of those skilled in the art.

[0025] Furthermore, the space inside the chassis 1 is divided into two compartments by the partition 11. The nitrogen generator assembly 2 and the air treatment assembly 3 are modularly arranged in the first compartment 12, while the electrical control assembly 4 and the frequency converter 5 are modularly arranged in the second compartment 13. This makes more rational use of the internal space of the nitrogen generator, and the nitrogen generator is small in size. During maintenance, the corresponding parts of the chassis 1 can be removed as needed, which facilitates maintenance operations. Moreover, the frequency converter 5 can not only control the start and stop of the nitrogen generator assembly 2 and the air treatment assembly 3, so that the working period of the nitrogen generator can be adjusted according to the actual needs of use, reducing the idling operation of the nitrogen generator during non-working periods, but also control the working frequency of the nitrogen generator assembly 2 and the air treatment assembly 3 according to the nitrogen production volume and nitrogen production duration, thereby achieving energy saving.

[0026] It needs to be further explained that, such as Figure 3 As shown, the top of the frame 23 is provided with a fixed frame 24, and the fixed frame 24 is provided with a plurality of first exhaust fans 25 in the inner circumference. The first exhaust fans 25 are electrically connected to the electronic control component 4.

[0027] The first exhaust fan 25 can extract the heat energy of the nitrogen generator 2 during operation, preventing the temperature inside the frame 23 from being too high and affecting the normal operation of the nitrogen generator 2.

[0028] Specifically, such as Figure 1 and Figure 5 As shown, the chassis 1 has a through hole 14 on one side of the first compartment 12. A fixing frame 15 is connected to the wall of the chassis 1 inside the through hole 14. A second exhaust fan 7 located inside the first compartment 12 is fixedly connected to the inner side of the fixing frame 15. The exhaust end of the second exhaust fan 7 is located in the middle of the fixing frame 15.

[0029] The hot air discharged by the first exhaust fan 25 is discharged into the first compartment 12 and then discharged to the outside of the first compartment 12 by the second exhaust fan 7. The heat generated in the first compartment 12 when the air treatment component 3 is working can also be discharged to the outside of the first compartment 12 by the second exhaust fan 7, thereby avoiding the excessive temperature in the first compartment 12 from affecting the normal operation of the nitrogen generation component 2 and the air treatment component 3.

[0030] It needs to be further explained that, such as Figure 5 and Figure 6 As shown, the walls of the chassis 1 at both ends of the second compartment 13 are provided with exhaust grilles 17.

[0031] The heat dissipated into the second compartment 13 by the electronic control component 4 and the frequency converter 5 during operation can be actively dissipated to the outside of the chassis 1 through the exhaust grille 17, thereby preventing the temperature inside the second compartment 13 from being too high and affecting the normal operation of the electronic control component 4 and the frequency converter 5.

[0032] It needs to be further explained that, such as Figure 1 and Figure 5 As shown, a first control panel 35 extending through the chassis 1 is provided on one side of the housing 34, and the first control panel 35 is electrically connected to the air handling assembly 3.

[0033] The first control panel 35 allows users to control the air handling unit 3 from outside the chassis 1. On the first control panel 35, the operating parameters of the cooler 31, filter 32 and dryer 33 can be adjusted according to the actual nitrogen generation needs, thereby adjusting the nitrogen generation frequency, nitrogen generation capacity, compressed air injection capacity and other operations of the nitrogen generator.

[0034] It needs to be further explained that, such as Figure 2 and Figure 6 As shown, one end of the frequency converter 5 is provided with a second control panel 51 that extends through the chassis 1 and is electrically connected to the frequency converter 5.

[0035] The second control panel 51 allows the user to control the inverter 5 from outside the chassis 1. The first control panel 35 allows the user to adjust the operating parameters of the inverter 5 according to the actual nitrogen generation needs, thereby adjusting the operating frequencies of both the nitrogen generation component 2 and the air treatment component 3.

[0036] It needs to be further explained that, such as Figure 5 As shown, four corners of the bottom of the chassis 1 are fixedly connected with casters 6.

[0037] The nitrogen generator can be moved using the 6-wheel mechanism, and its position can be fixed after it has been moved to a designated location, making the adjustment of the nitrogen generator's position more convenient.

[0038] Specifically, such as Figure 6 As shown, at least one handle 16 is provided on one side of the wall of the chassis 1.

[0039] The handle 16 can be used in conjunction with the wheel 6 to facilitate the movement of the nitrogen generator by the staff, making the movement of the nitrogen generator simpler.

[0040] It needs to be further explained that, such as Figure 2 , Figure 5 and Figure 6 As shown, the outer wall of the chassis 1 near the second compartment 13 where the electronic control component 4 is located is provided with several wiring ports 41, and the other side wall of the chassis 1 near the wiring ports 41 is provided with a cabinet door 18.

[0041] The wiring port 41 allows the external power supply to be connected to the electrical control component 4, while the cabinet door 18 allows the chassis 1 at the location of the electrical control component 4 to be opened freely, thus facilitating the operation of the staff to adjust or maintain the electrical control component 4.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
