Description

Technical Field

[0001] This utility model relates to the technical field of hydrogen refueling compressors, specifically to an intake air filtration device for a hydrogen refueling compressor. Background Technology

[0002] A hydrogen compressor is a device used to compress hydrogen. It can cool and purify the high-temperature, humid hydrogen from the electrolysis process, pressurize and transport it, and maintain the pressure of the hydrogen system to ensure the safe and stable operation of the electrolyzer. It plays an important role in hydrogen pressurization.

[0003] During long-term storage, hydrogen may become contaminated with impurities due to micro-leakage and other reasons. If these impurities are directly added to the vehicle's gas cylinder, they will eventually cause valve blockage and other malfunctions. Currently, the filter element is statically installed inside the filtration device, and impurities form a uniform filter cake layer on the surface of the filter element. As the operating time increases, the filtration resistance increases exponentially, requiring frequent shutdowns for cleaning or replacement of the filter element. Utility Model Content

[0004] The purpose of this invention is to provide an intake air filtration device for a hydrogenation compressor to solve the aforementioned defects caused by the prior art.

[0005] A hydrogenation compressor inlet filtration device includes a filter housing, an inlet pipe, an outlet pipe, and a columnar filter element. The inlet pipe is connected through one side of the filter housing, and a tank cover is connected to the top of the filter housing. A switching mechanism is provided inside the filter housing, which rotates the columnar filter element by driving a gear, so that the columnar filter elements inside the filter housing and the filter housing can remove impurities and dry the chlorine gas. A purification mechanism is provided inside the filter housing, which filters the injected chlorine gas through an interlocking arc-shaped filter screen, trapping rust and dust particles in the chlorine gas.

[0006] Preferably, the switching mechanism includes a servo motor, a drive housing, an annular gear disk, a columnar filter element, a bearing disk, and a drive gear. The servo motor is mounted on the top of the drive housing. A filter shell is welded to one side of the drive housing. An annular gear disk is disposed inside the drive housing. A columnar filter element is connected to the outer side of the annular gear disk. A protruding portion at the bottom of the bearing disk is connected to the top of the columnar filter element. A can lid is connected to the top of the bearing disk. The annular gear disk is disposed in the filter shell. The contact portion between the filter shell and the drive housing is an open structure.

[0007] Preferably, the drive housing is connected to the drive gear via a servo motor mounted at its top, and the drive gear meshes with an annular gear disc.

[0008] Preferably, the purification mechanism includes a flange, a second filter housing, an air outlet pipe, an arc-shaped filter screen, positioning posts, and positioning slots. One set of the flanges is disposed at the top of the second filter housing, and another set of the flanges is disposed at the bottom of the first filter housing. The air outlet pipe is connected through the bottom of the second filter housing. The positioning slots are distributed in a ring on the inner wall of the first filter housing. Positioning posts are connected to the outer side of the positioning slots. Arc-shaped filter screens are welded to the outer side of the two sets of positioning posts.

[0009] Preferably, the arc-shaped filter is connected to the inner wall of the filter shell through positioning posts on both sides, and the arc-shaped filter is parallel to the air intake pipe.

[0010] Preferably, the filter housing is bolted to another set of flanges via a flange connected to its bottom end.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. Dynamic filtration is achieved by driving the filter element to rotate through the meshing of a ring-shaped toothed disc and gears. The turbulence generated by the rotation causes impurities to be evenly distributed around the filter medium, maintaining unobstructed pores. Impurities are thrown off the surface of the filter material by centrifugal force, preventing deep penetration. At the same time, the ring-shaped toothed disc is used to install two sets of filter elements, so that the ring-shaped toothed disc rotates synchronously on the internal filter elements of filter shell one and filter shell two, thereby reducing the content of impurities in chlorine gas.

[0013] 2. When the arc-shaped filter screen is impacted by airflow, the mechanical locking of the positioning post and the slot can prevent the filter screen from shifting or vibrating, ensuring a stable filtration state under high-pressure chlorine gas flow. The filter screen can be pulled out by releasing the slot lock without disassembling the pipe bolts, thus saving the time of replacing the arc-shaped filter screen. The arc-shaped curved surface design increases the filtration area compared to the flat filter screen, improving the impurity interception capacity in the same space. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 6 As shown, a hydrogenation compressor inlet filtration device includes a filter housing 1, an inlet pipe 2, an outlet pipe 10, and a columnar filter element 12. The inlet pipe 2 is connected through one side of the filter housing 1, and a tank cover 3 is connected to the top of the filter housing 1. A switching mechanism 5 is provided inside the filter housing 1. The switching mechanism 5 rotates and switches the columnar filter element 12 through a drive gear 14, so that the columnar filter element 12 inside the filter housing 1 and the filter housing 2 can remove impurities and dry the chlorine gas. A purification mechanism 9 is provided inside the filter housing 1. The purification mechanism 9 filters the injected chlorine gas through an arc-shaped filter screen 15 that is engaged, and intercepts rust and dust solid particles in the chlorine gas.

[0024] In this embodiment, the switching mechanism 5 includes a servo motor 6, a drive housing 7, an annular gear disk 11, a columnar filter element 12, a bearing disk 13, and a drive gear 14. The servo motor 6 is mounted on the top of the drive housing 7. A filter shell 1 is welded to one side of the drive housing 7. An annular gear disk 11 is disposed inside the drive housing 7. The columnar filter element 12 is connected to the outer side of the annular gear disk 11. The top of the columnar filter element 12 is connected to the bottom protrusion of the bearing disk 13. A can cover 3 is connected to the top of the bearing disk 13. The annular gear disk 11 is disposed on the filter shell 1. The contact portion between the filter shell 1 and the drive housing 7 is an open structure. The drive gear 14 drives the columnar filter element 12 to rotate, while the bearing disk 13 positions the top of the columnar filter element 12.

[0025] In this embodiment, the drive housing 7 is connected to the drive gear 14 via a servo motor 6 at the top. The drive gear 14 meshes with the annular gear disk 11, which drives the columnar filter element 12 to be positioned and rotated, so that the chlorine gas can fully contact and filter the columnar filter element 12.

[0026] In this embodiment, the purification mechanism 9 includes a flange 4, a second filter housing 8, an air outlet pipe 10, an arc-shaped filter screen 15, positioning posts 16, and positioning slots 17. One set of flanges 4 is disposed at the top of the second filter housing 8, and another set of flanges 4 is disposed at the bottom of the first filter housing 1. The bottom of the second filter housing 8 is connected to the air outlet pipe 10. The positioning slots 17 are distributed in a ring on the inner wall of the first filter housing 1. The positioning posts 16 are connected to the outer side of the positioning slots 17. The arc-shaped filter screen 15 is welded to the outer side of the two sets of positioning posts 16. The positioning slots 17 are used to position and assemble the two sides of the arc-shaped filter screen 15, thereby reducing the difficulty of replacing the arc-shaped filter screen 15.

[0027] In this embodiment, the arc-shaped filter 15 is connected to the inner wall of the filter shell 1 through positioning posts 16 on both sides. The arc-shaped filter 15 is parallel to the air inlet pipe 2. The arc-shaped filter 15 filters solid impurities in chlorine gas, thereby reducing the dust and impurity content in chlorine gas.

[0028] In this embodiment, the filter housing 1 is bolted to another set of flanges 4 via a flange 4 connected to the bottom end, and the filter housing 1 and the filter housing 2 are assembled and positioned by the symmetrically arranged flanges 4.

[0029] In practical applications, this hydrogenation compressor inlet air filtration device includes the following functions:

[0030] Step 1: During use, first connect the top end of the bearing disk 13 to the bottom end of the can cover 3, then insert the protruding part of the bottom end of the bearing disk 13 into the inner end of the columnar filter element 12, then connect the bearing disk 13 and the columnar filter element 12 with bolts, then connect the bottom end of the columnar filter element 12 to the top end of the annular gear disk 11, and at the same time connect the other set of columnar filter elements 12 to the bottom end of the annular gear disk 11, so that the annular gear disk 11 meshes with the outer side of the drive gear 14;

[0031] Step 2: During use, the columnar filter element 12 is installed inside the filter housing 1 and the filter housing 8. The flange 4 on the outside of the filter housing 1 and another set of flanges 4 are fitted together. The two sets of flanges 4 are fastened with bolts. Then, the arc-shaped filter screen 15 is installed on the outside of the positioning column 16 and connected to it, so that the positioning column 16 and the positioning slot 17 are engaged. When the columnar filter element 12 rotates, the bearing disk 13 rotates with the columnar filter element 12, which also facilitates the suspension of the columnar filter element 12.

[0032] Step 3: The arc-shaped filter 15 is set parallel to one side of the air inlet pipe 2. Then, chlorine gas is directly introduced into the interior of the air inlet pipe 2 to trap rust and dust solid particles in the chlorine gas. Chlorine gas is then injected onto the surface of the columnar filter element 12. At the same time, the servo motor 6 is turned on, and the servo motor 6 drives the drive gear 14 to rotate. The drive gear 14 engages with the annular gear disk 11. The columnar filter element 12, with an activated carbon layer on the outer layer, removes residual moisture and organic pollutants in the chlorine gas.

[0033] Step 4: The columnar filter element 12 is filled with graphite-filled PTFE material, which is resistant to the corrosion of wet chlorine gas. The centrifugal force of rotation accelerates the diffusion of moisture from the columnar filter element 12 into the pores of activated carbon. After the activated carbon layer is saturated, hot nitrogen is used to desorb moisture and organic matter by rotation. Then, the chlorine gas is purified a second time by another set of columnar filter elements 12 set inside the filter shell 2 8. Finally, the filtered gas is injected into the compressor through the gas outlet pipe 10 set at the bottom of the filter shell 2 8.

[0034] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
