Description

Technical Field

[0001] The utility model relates to the technical field of denitration catalysts, and in particular to a denitration catalyst cleaning mechanism using gas injection. Background Art

[0002] With the improvement of environmental protection requirements, the selective catalytic reduction (SCR) technology used in the power, chemical, steel and other industries is crucial to reducing nitrogen oxide (NOx) emissions. However, after long-term operation, impurities will accumulate on the catalyst surface in the SCR system, resulting in decreased activity and reduced denitration efficiency. Traditional catalyst cleaning methods such as manual cleaning and mechanical cleaning have the disadvantages of low efficiency, high labor intensity, and easy damage to the catalyst. Therefore, this technology proposes a denitration catalyst cleaning mechanism using gas injection, which aims to efficiently and conveniently remove impurities on the catalyst surface by gas injection, restore its activity, and improve the operating efficiency and denitration performance of the SCR system.

[0023] Example

[0024] like Figure 1 to Figure 4As shown, this embodiment proposes a denitration catalyst cleaning mechanism using gas injection, including a catalyst unit 1, a shell 2 and two guide plates 7, a cleaning port 18 is provided on one side of the shell 2, a support plate 17 is fixedly connected to one side of the shell 2 by screws, a motor 3 is installed on the top of the support plate 17, an output end of the motor 3 is fixedly connected to a coaxially arranged rotating shaft 5 through a coupling, the rotating shaft 5 is rotatably installed inside the shell 2, two symmetrically arranged incomplete gears 8 are fixedly sleeved on the outer circumference of the rotating shaft 5, four symmetrically arranged fixing rods 6 are welded inside the shell 2, guide rods 16 are welded on both sides of the two guide plates 7, one of which The guide rod 16 is slidably assembled inside the fixed rod 6, and the bottom of the other guide rod 16 is fixedly connected to the connecting block 9 by screws. A number of symmetrically arranged brushes 11 are welded to the bottom of the connecting block 9. Two symmetrically arranged racks 12 are arranged inside the guide plate 7, and the incomplete gear 8 is meshed and connected with the rack 12. Through the arrangement of the incomplete gear 8 and the brush 11 and other structures, after the operator starts the motor 3, the motor 3 drives the rotating shaft 5 to drive the incomplete gear 8 to rotate, and then drives the guide plate 7 to reciprocate up and down. The guide plate 7 drives the brush 11 to move up and down through the connecting block 9, thereby realizing the cleaning of the channel 4 inside the catalyst unit 1.

[0025] like Figure 1 to Figure 4 As shown, a rotating rod 14 is rotatably installed inside the shell 2, and a synchronous belt 13 is jointly sleeved on the outer circumference of the rotating rod 14 and the rotating shaft 5 through a synchronous wheel. A fan 10 is fixedly sleeved on the outer circumference of the rotating rod 14, and a filter 15 is arranged inside the shell 2. Through the arrangement of structures such as the fan 10 and the filter 15, under the drive of the synchronous belt 13, the synchronous wheel rotates to drive the rotating rod 14 and the fan 10 to rotate, and the fan 10 generates strong wind to blow the stains removed by the brush 11 to the filter 15. The filter 15 effectively intercepts the stains through its fine mesh, thereby realizing the process of automatic cleaning and improving the cleaning efficiency.

[0026] like Figure 1 to Figure 4 As shown, a slide groove is provided inside the fixed rod 6, in which a guide rod 16 is slidably connected inside the slide groove, a plurality of channels 4 are provided inside the catalyst unit 1, and a brush 11 cooperates with the channels 4.

When the incomplete gear 8 is engaged with the rack 12 on the right side of the guide plate 7, the rotation of the incomplete gear 8 transmits power to the guide plate 7, causing it to move downward. When separated, the guide plate 7 stops moving. As the rotating shaft 5 continues to rotate, the incomplete gear 8 will gradually engage with the rack 12 on the left side of the guide plate 7. When the two are engaged, the guide plate 7 will start to move upward, thus realizing up and down reciprocating movement. The movement of the guide plate 7 drives the several brushes 11 at the bottom of the connecting block 9 to move up and down, thereby realizing the function of cleaning the several channels 4 opened inside the catalyst unit 1;

[0028] Furthermore, under the action of the synchronous belt 13, the synchronous wheel drives the rotating rod 14 to rotate.

The filter 15 has fine mesh holes and can effectively intercept these stains. After cleaning, the operator opens the cleaning port 18 and takes out the filter 15 for cleaning.
