Description

Technical Field

[0002] Currently, the amino acid process is the mainstream production process widely adopted by compound fertilizer manufacturers. This process involves feeding multiple metered raw materials into a drum granulator, adding sulfuric acid and ammonia during granulation, and maintaining a certain temperature and humidity for the materials. Granulation is achieved using an agglomeration method. The amino acid process has advantages such as high capacity, low energy consumption, and low operating costs. However, because ammonia is prone to escape during the reaction with the materials, it can cause excessive emissions of granulation tail gas, polluting the environment and affecting the normal lives of surrounding residents. The existing tail gas scrubbing technology uses a two-stage Venturi scrubbing method, which suffers from low efficiency, excessive fan resistance, high equipment cost, unsatisfactory scrubbing effect, and excessive tail gas emissions, failing to meet increasingly stringent environmental protection requirements.

[0003] In the existing technology, a closed water tank is directly set up and the gas supply pipe is integrated into the water tank. Exhaust gas is introduced to heat the water source. However, in the long term, scale and dirt are easy to remain in the water tank and gas supply pipe, which cannot be cleaned later and reduces the practicality.

[0004] Therefore, it is necessary to provide a device for utilizing the tail gas from the granulation of amino acid-based compound fertilizers to solve the above-mentioned technical problems. Utility Model Content

[0029] The cover 16 can be made of transparent explosion-proof glass, which makes it easy to observe the internal environment of the tank 19 and facilitates timely maintenance.

[0030] The cleaning component 4 includes a lead screw groove 48, which is fixedly connected to a vertical plate 413. The vertical plate 413 is fixedly connected to the support frame 3. A slider 410 is provided inside the lead screw groove 48. A connecting plate 415 is fixedly connected to the upper side of the slider 410. One end of a lead screw 49 is movably connected to the inner two ends of the lead screw groove 48. The lead screw 49 is threaded to the slider 410. One end of the lead screw 49 passes through one side of the lead screw groove 48. The output shaft of a motor 411 is fixedly connected to one end of the lead screw 49. The motor 411 is fixedly connected to one side of the lead screw groove 48.

[0031] The central shaft of the bevel gear 44 is movably connected to the vertical plate 413. The spline shaft sleeve 412 passes through and is fixedly connected to the center of the bevel gear 44. The spline shaft sleeve 412 passes through one of the annular cavities 13. The spline shaft sleeve 412 is movably connected to one side of the tank 19. The spline shaft sleeve 412 is slidably connected to the spline shaft 41. One end of the spline shaft 41 is fixedly connected to the rotating rod 47. The two ends of the rotating rod 47 are respectively fixedly connected to the annular rings 46. The two annular rings 46 respectively encircle the corresponding spiral tubes 17. The inner walls of the two annular rings 46 are respectively fixedly connected to a corresponding set of brushes 45.

[0032] The first bevel gear 44 meshes with the second bevel gear 43. The central shaft of the second bevel gear 43 is movably connected to the horizontal plate 414. The horizontal plate 414 is fixedly connected to the vertical plate 413. The end of the central shaft of the second bevel gear 43 is fixedly connected to the output shaft of the second motor 42. The second motor 42 is fixedly connected to the horizontal plate 414. The other end of the spline shaft 41 is movably connected to the connecting plate 415.

[0033] The support frame 3 is fixedly connected to the controller 2.

[0034] Controller 2 is electrically connected to motor 1 (411) and motor 2 (42).

[0035] The wiring diagrams of controller 2, motor 1 411 and motor 2 42 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the wiring diagrams of controller 2, motor 1 411 and motor 2 42 will not be explained in detail.

[0036] The working principle is as follows: When in use, the air inlet pipe 15 is connected to the tail gas discharge pipe of the granulation of amino acid compound fertilizer, the water inlet pipe 14 is connected to the external cold water inlet pipe, and the water outlet pipe 11 is connected to the external hot water storage tank or the employee dormitory in the factory area for supply. When the gas enters an annular cavity 13 from the air inlet pipe 15 and is transmitted through two spiral pipes 17, the cold water enters the tank 19 through the water inlet pipe 14 and is heated by the spiral pipes 17. The serpentine distribution of the two spiral pipes 17 makes the heat conduction area larger and the heating effect better. The heated water is discharged through the water outlet pipe 11, and the tail gas is discharged through the exhaust pipe 12.

[0037] When it is necessary to clean the scale and dirt on the outer wall of the spiral tube 17, the controller 2 controls the second motor 42 to rotate. The second motor 42 drives the second bevel gear 43 to rotate. The second bevel gear 43 meshes with the first bevel gear 44 to rotate. The first bevel gear 44 drives the spline shaft 41 to rotate through the spline shaft sleeve 412. The spline shaft 41 drives the annular ring 46 to rotate through the rotating rod 47. The annular ring 46 drives a set of brushes 45 to rotate along the spiral tube 17. At the same time, the controller 2 controls the first motor 411 to start. When the motor 411 drives the lead screw 49 to rotate, the lead screw 49 drives the slider 410 to slide. The slider 410 drives the spline shaft 41 to slide along the spline shaft sleeve 412 through the connecting plate 415. At the same time, the spline shaft 41 drives the annular ring 46 and the brush 45 to move through the rotating rod 47. In summary, when the annular ring 46 drives the brush 45 to rotate and move, the brush 45 moves along the trajectory of the spiral tube 17, so that the brush 45 can clean the scale and dirt on the outer wall of the spiral tube 17.

[0038] Furthermore, both covers 16 can be opened to inspect or repair the inside of the tank 19 through the inspection port 18, which is convenient and quick.

[0039] Compared with related technologies, this utility model has the following beneficial effects: In use, the heated water is discharged through the outlet pipe 11 via the heat exchange component 1. When it is necessary to clean the scale and dirt on the outer wall of the spiral tube 17, the cleaning component 4 causes the annular ring 46 to rotate and move the brush 45, so that the brush 45 moves along the trajectory of the spiral tube 17, thereby cleaning the scale and dirt on the outer wall of the spiral tube 17.
