[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1-4 As shown, a 3-aminopropanol residual hydrogen recovery device of the utility model comprises: a tank body 1, on which an air inlet pipe 2 and an air outlet pipe 3 are arranged; a water collecting frame 4, which is arranged below the tank body 1, and a filter frame 5 is arranged inside the water collecting frame 4; a water storage tank 6, which is arranged on one side of the tank body 1, the water storage tank 6 is connected to the water collecting frame 4 through a first pump box 7, and the water storage tank 6 is connected to a water spray pipe 8 through a second pump box 20; and a scattering mechanism 9, which is arranged inside the tank body 1.

[0023] In this embodiment, the water sprayed from the water spray pipe 8 can be collected by the water collecting frame 4, and then the first pump box 7 is operated to pump the water in the water collecting frame 4 into the water storage tank 6 for storage, and then the water stored in the water storage tank 6 is re-sprayed into the tank body 1 through the second pump box 20 for reuse, so that the water can be recycled, reducing the water usage and saving costs.

[0024] like Figure 1 and Figure 2As shown, specifically, a refrigerator 10 is provided on the water tank 6, a water level gauge 11 is provided on one side of the water tank 6, and a water adding pipe 12 is provided above the water tank 6; the water in the water tank 6 is cooled by the refrigerator 10, and the generated cooling water will enter the tank body 1 to cool the hydrogen, and the temperature can be reduced while removing impurities, the water level in the water tank 6 can be observed by the water level gauge 11, and water can be added through the water adding pipe 12 when the water volume is insufficient.

[0025] Refrigerator 32 adopts a conventional refrigerator. When the refrigeration cycle starts, the refrigerant gas is sucked in and compressed by the compressor to become a high-pressure and high-temperature gas; the high-pressure and high-temperature refrigerant gas enters the condenser, contacts the external cold source, dissipates heat and cools, and the refrigerant gas becomes a high-pressure liquid; the high-pressure liquid refrigerant enters the evaporator through the throttling device, and due to the reduction in pressure, the liquid refrigerant quickly evaporates into a low-temperature and low-pressure gas, absorbing heat in the process, thereby reducing the temperature of the surrounding environment or the refrigerated object; the low-temperature and low-pressure gaseous refrigerant in the evaporator contacts the object to be refrigerated, absorbs the heat of the object, reduces the temperature of the object, and turns the refrigerant into a gas again; the low-temperature and low-pressure gas after evaporation is sucked in by the compressor again to start the next round of circulation.

[0026] like Figure 2 and Figure 3 As shown, specifically, a limiting frame 13 is arranged inside the water collecting frame 4, the filter frame 5 is slidably connected to the limiting frame 13, a filter screen 14 is detachably connected inside the filter frame 5, and a handle 15 is arranged on the outside of the filter frame 5; the recovered water can be filtered by the filter screen 14, and the filter frame 5 can be conveniently taken out of the water collecting frame 4 by pulling the handle 15, so that the debris on the filter frame 5 can be cleaned conveniently, and the filter screen 14 can be detachably connected inside the filter frame 5, so that the filter screen 14 can be conveniently inspected and replaced, thereby enhancing the practicability of the device.

[0027] like Figure 2 and Figure 4 As shown, specifically, the breaking mechanism 9 includes a driving motor 91, which is connected to a rotating shaft 92 at the bottom, stirring rods 93 are evenly fixed on the rotating shaft 92, and a dispersion disk 94 is installed on the stirring rods 93, and a plurality of stirring rods 93 and dispersion disks 94 are provided.

[0028] In this embodiment, the rotating shaft 92 is driven to rotate by the driving motor 91, which can drive the rotating shaft 92 and the dispersion disk 94 installed on the stirring rod 23 to rotate, so that the water sprayed by the nozzle 19 collides with the rotating dispersion disk 94, which will produce larger water bubbles, and then the water increases the contact area with impurities in the hydrogen, adsorbs the impurities, and obtains cleaner hydrogen.

[0029] like Figure 1 and Figure 2As shown, specifically, the first pump box 7 is connected to the water collecting frame 4 through the first water pipe 16, the second pump box 20 is connected to the water storage tank 6 through the second water pipe 17, and the second pump box 20 is connected to the water spray pipe 8 through the third water pipe 18. At least two nozzles 19 are arranged on the water spray pipe 8; by arranging multiple nozzles 19, the spraying effect is enhanced.

[0030] Working principle: the water sprayed from the water spray pipe 8 can be collected by the water collecting frame 4, and then the first pump box 7 works to pump the water in the water collecting frame 4 into the water storage tank 6 for storage, and then the water stored in the water storage tank 6 is sprayed back into the tank body 1 through the second pump box 20 for reuse, so that the water can be recycled, the water usage is reduced, and the cost is saved. The water in the water storage tank 6 is cooled by the refrigerator 10, and the generated cooling water will enter the tank body 1 to cool the hydrogen, and the temperature can be reduced while removing impurities. The water level in the water storage tank 6 can be observed by the water level meter 11, and water can be added through the water adding pipe 12 when the water volume is insufficient.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
