Description

Technical Field

[0001] The invention belongs to the technical field of ammonia-based desulfurization and ammonia removal, and specifically is a novel ammonia-based desulfurization and ammonia removal system based on the filtering principle. Background Art

[0002] In existing desulfurization and ammonia removal systems, polypropylene fillers are usually used for filtration. However, polypropylene fillers mainly rely on the removal method of collision filtration, which has strict requirements on the flow rate range of flue gas. When the flue gas flow is too large or too small to meet the flow rate conditions required for filtration, the filtration effect of the system will be greatly reduced, and it will be difficult to effectively reduce ammonia escape and reduce the emission of aerosols. This sensitivity to flow rate limits its applicability under variable working conditions, limiting the overall removal capacity of the system.

[0003] In addition, the maintenance of polypropylene packing also faces many challenges. As the running time increases, impurities tend to accumulate on the surface of the packing, resulting in a decrease in filtration efficiency. In order to maintain the normal operation of the system, it is necessary to manually clean and replace the polypropylene packing regularly. This operation is not only time-consuming and labor-intensive, but also poses a safety hazard. During the cleaning and replacement process, the operator needs to enter the tank, which is prone to safety accidents due to improper operation or harsh environment, posing a threat to the safety of the operator.

[0026] 5. In the present invention, the original filtering method using polypropylene filler is changed, because it adopts a collision filtration removal method. This method has strict requirements on the flow rate range of flue gas. When the flue gas flow is too large or too small and cannot meet the filtration flow rate, it is impossible to achieve the expected effect of reducing ammonia escape and reducing aerosol efflux, and there are certain limitations on the removal capacity of ammonia escape and aerosol.

DETAILED DESCRIPTION

[0036] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1:

[0038] See also Figure 1-Figure 8The present application provides a novel ammonia-based desulfurization and ammonia removal system based on the filtering principle, comprising a tank body 1, and also comprising: a spreading mechanism 2, which is arranged inside the tank body 1 and is used to spread the replaced fiber ceramic filler; the spreading mechanism 2 comprises a connecting seat 21 fixedly installed inside the tank body 1, a No. 1 driving motor 22 is fixedly installed on the connecting seat 21, a No. 1 transmission shaft 24 is fixedly installed at the output end of the No. 1 driving motor 22, and the No. 1 driving motor 22 is rotatably connected to the connecting seat 21, a No. 1 auger conveying assembly 25 is fixedly installed on the end of the No. 1 transmission shaft 24 away from the No. 1 driving motor 22, and a No. 2 transmission shaft 2 arranged vertically therewith is arranged below the No. 1 transmission shaft 24. 6, and the No. 1 transmission shaft 24 and the No. 2 transmission shaft 26 are connected by a steering gear set 23, the No. 1 connecting shaft 27 is slidably connected inside the No. 2 transmission shaft 26, a limiting strip 28 is fixedly installed on the No. 1 connecting shaft 27, and a reset spring 29 is provided between the No. 2 transmission shaft 26 and the No. 1 connecting shaft 27 for resetting the No. 1 connecting shaft 27, a spreading plate 210 is fixedly installed on the lower end of the No. 1 connecting shaft 27, and the bottom surface of the spreading plate 210 is arranged in an inclined manner, a feed port 15 is provided on the tank body 1, and a No. 1 auger conveying assembly 25 is arranged inside the feed port 15, and a discharge port 14 is also provided on the tank body 1, and a No. 2 auger conveying assembly 6 is provided inside the discharge port 14.

[0039] Specifically, because the fiber ceramic filler is a consumable, the filler needs to be replaced frequently. Therefore, the No. 1 drive motor 22 can be started to drive the No. 1 transmission shaft 24 to rotate, and the No. 1 transmission shaft 24 drives the No. 1 auger conveying assembly 25 to rotate inside the feed port 15. At the same time, by pouring the fiber ceramic filler into the feed port 15, the No. 1 auger conveying assembly 25 can prevent blockage during the addition of the fiber ceramic filler, and the fiber ceramic filler entering from the feed port 15 falls into the inside of the carrier plate 5. When the No. 1 transmission shaft 24 rotates, the No. 2 transmission shaft 26 can be driven to rotate through the steering gear set 23, and the No. 2 transmission shaft 26 drives the No. 1 connecting shaft 27 and the limit bar 28 below to rotate. The function of the limit bar 28 is to be able to The No. 1 connecting shaft 27 is made to slide along the No. 2 transmission shaft 26, and the No. 1 connecting shaft 27 can be driven to rotate while the No. 2 transmission shaft 26 rotates. The rotation of the No. 1 connecting shaft 27 drives the multiple spreading plates 210 below to rotate. The spreading plates 210 spread the fiber ceramic filler that falls into the inside of the supporting plate 5. Because the bottom surface of the spreading plate 210 is arranged at an angle, the resistance can be reduced in the process of spreading the fiber ceramic filler, and the energy output of the No. 1 driving motor 22 can be reduced. The motor drives the auger conveying assembly and the transmission shaft, and then the spreading plate 210 is rotated through the transmission of the steering gear, so that the fiber ceramic filler is spread evenly during the addition process to avoid the problem of uneven distribution caused by the accumulation of fiber ceramic fillers, which in turn affects the desulfurization and ammonia removal effect.

[0040] Embodiment 2:

[0041] On the basis of the above embodiments, a feeding mechanism 3 is arranged below the spreading mechanism 2, and is used for discharging the fiber ceramic filler that needs to be replaced; the feeding mechanism 3 includes a No. 2 driving motor 31 fixedly mounted on the outer wall of the tank body 1, and a rotating wheel 32 is fixedly mounted on the output end of the No. 2 driving motor 31, and an eccentric shaft 33 is eccentrically arranged on the rotating wheel 32, and a connecting rod 34 is rotatably mounted on the eccentric shaft 33, and a No. 2 slider 35 is rotatably mounted on the end of the connecting rod 34 away from the eccentric shaft 33, and a sliding rod 36 is fixedly mounted on the No. 2 slider 35.

[0042] Specifically, when the fiber ceramic filler above the supporting plate 5 needs to be replaced, the No. 2 driving motor 31 is started to drive the rotating wheel 32 to rotate 180 degrees, and the rotating wheel 32 drives the eccentric shaft 33 to rotate, and the eccentric shaft 33 lifts the connecting rod 34, and the connecting rod 34 drives the No. 2 slider 35 and the sliding rod 36 arranged on the No. 2 slider 35 to slide upward relative to the annular support plate 16, and the sliding rod 36 lifts the group of guide mechanisms 7 fixed thereon, while the height of the group of guide mechanisms 7 fixed on the annular support plate 16 remains unchanged, that is, the end of the supporting plate 5 away from the discharge port 14 is lifted, and the fiber ceramic filler flows from the discharge chute 52 on the enclosure 51 to the discharge port 14. Before this, the fiber ceramic filler can be discharged from the inside of the tank body 1 by starting the No. 2 auger conveying assembly 6 inside the annular support plate 16. Compared with the manual discharge of the fiber ceramic filler, this method is more efficient and safer.

[0045] Specifically, while the fiber ceramic filler inside the supporting plate 5 is discharged through the unloading mechanism 3, the No. 2 slider 35 in the unloading mechanism 3 lifts the No. 3 connecting shaft 37, and the No. 3 connecting shaft 37 lifts the No. 1 slider 213, and the No. 1 connecting block 211 drives the No. 1 connecting shaft 27 to slide upward along the No. 2 transmission shaft 26 through the No. 2 connecting shaft 212, and the No. 1 connecting block 211 drives the No. 1 connecting shaft 27 to slide upward along the No. 2 transmission shaft 26, and the return spring 29 is compressed. When the No. 1 connecting shaft 27 moves downward, the No. 1 connecting shaft 27 can be pushed downward by the elastic force of the return spring 29. At this point, even if one end of the supporting plate 5 is lifted up, the spreading plate 210 will not block the supporting plate 5, so as to avoid the supporting plate 5 being stuck.

Because the articulated seat 71 and the No. 2 connecting block 72 are hinged, they can adapt to the change of the angle of the bearing plate 5 during the rotation process, and inserting the guide shaft 73 into the slot at the lower end of the bearing plate 5 can avoid the bearing plate 5 from being misplaced during the process of being lifted, which affects the normal use of the desulfurization and ammonia removal system.
