Description

Technical Field

[0001] The utility model relates to the field of desulfurization towers, in particular to a dust treatment device for an activated carbon desulfurization tower. Background Art

[0002] Activated carbon desulfurization tower is a process equipment that uses the adsorption and catalytic effect of activated carbon to remove SO2 from flue gas. Its basic principle and process flow mainly consist of three parts: activated carbon adsorption, desorption regeneration and sulfur recovery system.

[0003] With the enhancement of environmental protection awareness and the continuous improvement of emission standards, activated carbon desulfurization tower, as an important environmental protection equipment, plays an increasingly important role in industrial waste gas treatment. In the actual operation process, the dust problem on the inner wall of the activated carbon desulfurization tower has gradually become a key factor affecting its performance and service life.

[0004] In the desulfurization process of traditional activated carbon desulfurization tower, dust and impurities in the exhaust gas will gradually accumulate on the inner wall of the tower, forming a stubborn dust layer. These dusts will not only reduce the desulfurization efficiency, but also affect the normal operation of the equipment. What is more noteworthy is that the dust attached to the inner wall of the tower is often easily ignored and there are many difficulties in handling it.

[0005] The dust on the inner wall of the tower is often tightly attached to the tower wall and is difficult to completely remove by simple cleaning or flushing. Traditional cleaning methods such as mechanical cleaning and water flushing have limited effects when dealing with such stubborn dust and cannot completely remove the dust layer. The cleaning of the inner wall of the tower usually needs to be carried out when the equipment is shut down, which not only affects the production progress, but also increases the maintenance cost. For large desulfurization towers, internal cleaning is difficult and poses a safety risk. Utility Model Content

[0040] Reference Figure 4-Figure 6 The cleaning plate 4 includes: a cleaning brush roller 5, which is installed on the cleaning plate 4 and directly contacts the inner wall of the desulfurization tower 1. The cleaning brush roller 5 is designed to be able to rotate on the cleaning plate 4 when the cleaning plate 4 moves; two cleaning scrapers 6, which are installed on the cleaning plate 4 and arranged on both sides of the cleaning brush roller 5, are used to assist in cleaning the dust on the inner wall of the desulfurization tower 1. The cleaning plate 4 is equipped with a cleaning brush roller 5 and two cleaning scrapers 6. The cleaning brush roller 5 is directly in contact with the inner wall of the desulfurization tower 1. When the cleaning plate 4 moves, the cleaning brush roller 5 can rotate on the cleaning plate 4, and the attached dust is brushed off through the friction between the bristles and the inner wall. This self-rotation design increases the contact area between the cleaning brush roller 5 and the inner wall, and improves the cleaning efficiency. The two cleaning scrapers 6 are installed on both sides of the cleaning brush roller 5, and are used to assist in cleaning the dust on the inner wall of the desulfurization tower 1. They can scrape off the stubborn dust that has been brushed off but may still adhere to the inner wall, thereby ensuring the cleanliness of the inner wall.

[0041] Referring to 6, a mounting groove 14 is provided on one side of the cleaning plate 4, and the cleaning brush roller 5 is installed in the mounting groove 14; the cleaning brush roller 5 includes: a connecting rod 12, one end of which passes through the side wall of the mounting groove 14 and extends to the outside of the cleaning plate 4, and the other end is rotated on the cleaning brush roller 5; a gear 13 is installed on the connecting rod 12; a groove 10 is provided at the bottom of the mounting plate 2, and a rack 11 is connected to the groove 10, and the rack 11 is connected to the gear 13. When the rotating plate 3 rotates, the cleaning plate 4 moves along the inner wall of the desulfurization tower 1, and the cleaning plate 4 drives the gear 13 to mesh with the rack 11, and the gear 13 rotates and drives the connecting rod 12 and the cleaning brush roller 5 to rotate.

[0042] Reference Figure 4 and Figure 5The mounting plate 2 includes: a first driving wheel 7, mounted on the outer ring of the rotating plate 3; a power source 8, mounted on the mounting plate 2, for providing rotational power; a second driving wheel 9, mounted on the power shaft of the power source 8, the second driving wheel 9 is connected to the first driving wheel 7, the power source 8 adopts a servo motor, and can also adopt a stepping motor. The power source 8 drives the second driving wheel 9 to rotate, and the second driving wheel 9 can drive the first driving wheel 7 to rotate, thereby driving the rotating plate 3 to rotate on the mounting plate 2.

[0043] Reference Figure 3 and Figure 4 The projection shape of the groove 10 is a circular ring, and the projection shape of the rack 11 is a circular ring.

[0044] Reference Figure 4 The projection shapes of the mounting plate 2 and the rotating plate 3 are both circular rings, the outer diameter of the rotating plate 3 is smaller than the inner diameter of the mounting plate 2, the mounting plate 2 and the rotating plate 3 are both circular ring designs, and the outer diameter of the rotating plate 3 is smaller than the inner diameter of the mounting plate 2, which ensures that the rotating plate 3 can rotate smoothly inside the mounting plate 2 while avoiding interference or collision with the mounting plate 2.

[0045] During use, the dust treatment device of the activated carbon desulfurization tower 1 is started, and the power source 8 drives the second driving wheel 9 to rotate, thereby driving the first driving wheel 7 to rotate. The first driving wheel 7 is installed on the outer ring of the rotating plate 3, so the rotating plate 3 starts to rotate around the center of the mounting plate 2. The rotation of the rotating plate 3 drives the cleaning plate 4 to perform a circular motion on the inner wall of the desulfurization tower 1. The cleaning plate 4 fits tightly with the inner wall of the desulfurization tower 1 to ensure that every corner of the inner wall of the desulfurization tower 1 can be covered during the movement. The cleaning brush roller 5 is in direct contact with the inner wall of the desulfurization tower 1. When the rotating plate 3 rotates, the cleaning plate 4 moves along the inner wall of the desulfurization tower 1, and the cleaning plate 4 drives the gear 13 to mesh with the rack 11. The wheel 13 rotates and drives the connecting rod 12 and the cleaning brush roller 5 to rotate. The self-rotation of the cleaning brush roller 5 brushes off the attached dust through the friction between the bristles and the inner wall. Two cleaning scrapers 6 are installed on both sides of the cleaning brush roller 5. They can scrape off the stubborn dust that has been brushed off but may still adhere to the inner wall. With the continuous rotation of the rotating plate 3, the cleaning plate 4, the cleaning brush roller 5 and the cleaning scraper 6 continuously perform a circular motion on the inner wall of the desulfurization tower 1 to achieve cleaning without dead angles. The cleaned dust can be collected and processed by the collection device at the bottom of the desulfurization tower 1. When the dust on the inner wall of the desulfurization tower 1 is cleaned, the staff can turn off the power source 8 to stop the operation of the dust treatment device.

[0046] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0047] Through the combination of the rotating plate 3 and the cleaning plate 4, the cleaning brush roller 5 on the cleaning plate 4 can be in close contact with the inner wall of the desulfurization tower 1 and rotate on its own. Through the friction between the bristles and the inner wall, the tightly attached stubborn dust can be effectively removed. The presence of the cleaning scraper 6 can further scrape off the residual dust to ensure the cleanliness of the inner wall.

This comprehensive cleaning not only improves the cleaning efficiency, but also ensures the overall cleanliness of the inner wall of the desulfurization tower 1.
