[0032] Example 3, a desulfurization tower, including the desulfurization tower flue inlet flushing device, working process analysis: Start-up and preparation phase: The cleaning personnel first ensure that the container is filled with cleaning liquid and start the pump. The pump sucks the cleaning liquid in the container through the suction pipe and delivers it to the connecting hose.

[0033] The cleaning staff holds the grip sleeve and moves it to the left. At the same time, the reduction motor starts to work and drives the driving gear ring to rotate. As the driving gear ring meshes with the gear ring, the gear ring drives the grip sleeve and the rotating tube to rotate on the support frame. The rotation direction of the rotating tube is controlled by the forward and reverse rotation of the reduction motor to achieve reciprocating rotation.

[0034] Cleaning fluid distribution and pressurization stage: The cleaning fluid enters the transfer pipe through the connecting hose and is then distributed to the diverter pipe, which further distributes the cleaning fluid to each branch pipe and then enters the arc pressure supply pipe.

[0035] After the cleaning liquid in the arc-shaped pressure supply pipe is pressurized, it is sprayed out through multiple impact pipes, forming a strong scouring of the inner wall of the flue inlet of the desulfurization tower.

[0036] Two-way coverage flushing stage: The shunt pipe simultaneously delivers cleaning fluid to the injection pipe, and after the cleaning fluid enters the booster pipe, it is distributed to the shunt branch pipe, which then distributes the cleaning fluid to multiple connecting pipes.

[0037] The connecting pipe transports the cleaning liquid to the side spray pipe and the butt pipe respectively. The side spray pipe directly washes the inner wall of the desulfurization tower vertically, while the butt pipe transports the cleaning liquid to the ring pipe, which is then distributed to multiple atomizing side spray pipes for horizontal washing.

[0038] The combined use of atomizing side nozzles and side nozzles realizes all-round and multi-angle flushing of the inner wall of the desulfurization tower, ensuring the cleaning effect.

[0039] Displacement and adjustment stage: During the entire flushing process, the reciprocating rotation of the grip sleeve and the rotating tube, as well as the movement of the diverter tube (if the design allows), enables the flushing device to cover a wider area and improve flushing efficiency.

[0040] The squeeze rollers are supported by pillars and support rods and move with the movement of the rotating tube, and may play a role in assisting cleaning or maintaining the stability of the flushing device.

[0041] Beneficial effect analysis: Efficient cleaning: Through the combined use of multiple impact tubes, side nozzles and atomizing side nozzles, the inner wall of the flue inlet of the desulfurization tower is flushed in all directions and at multiple angles, greatly improving the cleaning efficiency.

[0042] Flexible position adjustment: The reciprocating rotation of the grip sleeve and the rotating tube, as well as the movement of the diverter tube (if the design allows), enables the flushing device to flexibly adjust the flushing angle and position to adapt to the flue inlets of desulfurization towers of different shapes and sizes.

[0043] High degree of automation: The use of reduction motor realizes the automatic control of the flushing device, reduces the labor intensity of cleaning personnel and improves work efficiency.

[0044] Compact structure: The entire flushing device has a compact structure, occupies a small space, and is easy to install and use inside the desulfurization tower.

[0045] Easy maintenance: The various parts of the flushing device are tightly connected and easy to disassemble, making it easy to maintain and replace when necessary.

[0046] Environmental protection and energy saving: Through the rational use of cleaning fluid and flushing methods, resource waste and environmental pollution are reduced, which is in line with the concept of environmental protection and energy saving.

[0047] The working principle of the flue inlet flushing device of the desulfurization tower of the present invention is as follows: First, when the present invention is displaced, by adding cleaning liquid inside the container 11, the cleaning personnel hold the outer wall of the grip sleeve 3 and move to the left, the grip sleeve 3 carries the rotating tube 1 to move to the left, the rotating tube 1 drives the diverter tube 13 to move to the left, the diverter tube 13 drives multiple pillars 17 to move to the left, and the pillars 17 carry the support rod 18 to move to the left. The support rod 18 drives the extrusion roller 19 to move, and the extrusion roller 19 realizes the extrusion movement along the inner wall of the flue inlet of the desulfurization tower. By starting the reduction motor 7, the grip sleeve 3 supports the support frame 8, the support frame 8 supports the reduction motor 7, and the reduction motor 7 drives the driving gear ring 6 to rotate. The driving gear ring 6 carries the gear ring 4 to rotate, and the gear ring 4 carries the grip sleeve 3 to rotate. The grip sleeve 3 rotates forward on the outer wall of the rotating tube 1 and then reverses, so that the gear ring 4 drives the rotating tube 1 to rotate forward and reverse, and the rotating tube 1 drives the diverter tube 13 to rotate back and forth.

[0048] Secondly, when the present invention is diverted and shifted, after the cleaning liquid is poured into the container box 11, the suction pipe 10 is started by the pump 9, and the suction pipe 10 sucks the cleaning liquid inside the container box 11, and the cleaning liquid is poured into the connecting hose 2, and is transported to the rotating pipe 1 through the connecting hose 2, and poured into the diverter pipe 13 from the rotating pipe 1. The diverter pipe 13 diverts the cleaning liquid into multiple branch pipes 14, and pours it into the arc-shaped pressure supply pipe 15 through the branch pipe 14. The arc-shaped pressure supply pipe 15 diverts and pours it into multiple impact pipes 16, and the multiple impact pipes 16 pressurize and divert it to the outside. The multiple impact pipes 16 can realize the cleaning operation of the impurities on the inner wall of the flue inlet of the desulfurization tower.

[0049] Then, the present invention covers the displacement in both directions, and the cleaning liquid is poured into the filling pipe 20 through the shunt pipe 13, and transported to the boosting pipe 21 through the filling pipe 20, and poured into the shunt branch pipe 22 from the boosting pipe 21. The shunt branch pipe 22 is shunted into the connecting pipe 23, and shunted into multiple side nozzles 24 one by one by multiple connecting pipes 23. One of the side nozzles 24 pours the cleaning liquid into the butt pipe 25, and pours it into the annular pipe 26 through the side nozzle 24, and pours it into multiple connecting pipes 27 from the annular pipe 26. The connecting pipe 27 pours it into the atomizing side nozzle 28, and the atomizing side nozzle 28 sprays and flushes it laterally, so that multiple atomizing side nozzles 28 flush the inner wall of the desulfurization tower horizontally, and multiple side nozzles 24 can flush multiple points on the vertical outside of the desulfurization tower.
