[0017] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0018] This utility model provides a melamine feeding tail gas recovery device, which can solve the problem of unqualified melamine feeding emissions affecting the surrounding environment in related technologies.

[0019] See Figure 1 As shown in the illustration, a melamine feeding tail gas recovery device according to an embodiment of this utility model includes: a packaging silo 1; an ammonia scrubbing tower 3 connected to the packaging silo 1 via an inlet pipe 2, the ammonia scrubbing tower 3 being connected to a scrubbing pump 4, and a water outlet pipe 5 at the lower end of the ammonia scrubbing tower 3; and a carbonization section equipment 6 connected to the water outlet pipe 5. The packaging silo 1 is vented and then discharged after being scrubbed by the ammonia scrubbing tower 3, significantly reducing the ammonia content and solving environmental hazards. The recycled ammonia water is sent to the carbonization section equipment 6 for use, reducing production costs and achieving certain economic benefits.

[0020] See Figure 1 As shown, in some embodiments, a drying device 7 is installed at one end of the air inlet pipe 2 near the packaging hopper 1. When the packaging hopper 1 is vented through the air inlet pipe 2, the ammonia gas contains moisture and forms ammonia water, which can undergo a slow chemical reaction with iron, causing corrosion to the air inlet pipe 2 and affecting its service life. By setting the drying device 7, the humidity of the ammonia gas can be reduced, thereby reducing pipe corrosion and extending its service life.

[0021] See Figure 1 As shown, in some embodiments, the drying device 7 includes a drying box 71, with multiple ventilation holes 72 on both sides of the drying box 71. The drying box 71 contains a desiccant, which can be silica gel desiccant, mineral desiccant, quicklime desiccant, calcium chloride desiccant, alumina desiccant, etc. After the gas enters the drying box 71 and is dried by the desiccant, it enters the air inlet pipe 2 through the ventilation holes 72.

[0022] See Figure 2 As shown, in some embodiments, the drying box 71 is detachably installed at one end of the air inlet pipe 2, and the drying box 71 can be removed to facilitate timely replacement of the desiccant.

[0023] See Figure 2 As shown, in some embodiments, the drying box 71 is cylindrical, and the two ends of the drying box 71 are provided with connecting pipes 73. The connecting pipes 73 are sleeved on the inside of the air inlet pipe 2 to facilitate the connection between the drying box 71 and the connecting pipes 73.

[0024] See Figure 2 As shown, in some embodiments, the outer side of the connecting pipe 73 is provided with a mounting groove 74, and a sealing ring 75 is installed in the mounting groove 74, which can form a seal between the drying box 71 and the connecting pipe 73 to prevent gas leakage.

[0025] See Figure 2 As shown, in some embodiments, at least two drying boxes 71 are provided, and the two drying boxes 71 are connected by the connecting pipe 73. Multiple drying boxes 71 can be installed as needed. Each drying box 71 contains different types of desiccants to improve the drying effect, or it can contain coolants to reduce the temperature of ammonia.

[0026] See Figure 2As shown, in some embodiments, connecting blocks 76 are provided on the outer sides of both ends of the drying box 71. The connecting blocks 76 are provided with connecting holes 77, and connecting bolts 78 are installed in the connecting holes 77. The two drying boxes 71 are connected by the connecting bolts 78. The drying box 71 is connected to the air outlet of the packaging hopper 1 and the air inlet pipe 2 by the connecting bolts 78. By using the connecting bolts 78, the connection strength between the drying boxes 71 is further increased, ensuring the stability of the system operation and preventing ammonia leakage.

[0027] See Figure 2 As shown, in some embodiments, the connecting block 76 is annular and arranged around the outer side of the drying box 71. The connecting blocks 76 on the outer sides of the two drying boxes 71 can be aligned and connected, further improving the sealing effect and preventing gas leakage.

[0028] See Figure 1 As shown, in some embodiments, a temperature and humidity sensor 8 is installed on the inner side of the end of the air inlet pipe 2 near the packaging hopper 1. The temperature and humidity sensor 8 can detect the temperature and humidity of the gas, and adjust the quantity of the drying box 71 and the type of desiccant according to the data to ensure the drying effect. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0029] It is understood that spatial relation terms such as "below," "under," "below," "below," "above," "above," etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as "below" or "below" of the other element or feature will be oriented "above" the other element or feature. Therefore, the exemplary terms "below" and "below" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0030] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.

[0031] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.
