Technical Field

[0001] The utility model relates to the technical field of flue cleaning, in particular to a flue inlet flushing device for a desulfurization tower. Background Art

[0002] The desulfurization tower is responsible for discharging the flue gas after desulfurization treatment into the atmosphere; the flue of the desulfurization tower is mainly used to guide the flue gas to the desulfurization tower, and the flue gas is then treated by the desulfurization tower and finally discharged into the atmosphere.

[0003] During the process of the flue gas entering the desulfurization tower through the flue, dirt and sediments will accumulate in the flue. If not cleaned for a long time, the dirt and sediments will block the flue. Currently, water or cleaning agents are generally used to flush the inner wall of the flue gas pipeline, but it is difficult to clean the dirt and sediments stubbornly adhering to the inner wall of the flue. The cleaning efficiency of the flue is low and the cleaning effect is not good. Summary of the Invention

[0004] In order to solve the problem that the dirt stubbornly adhering to the flue is difficult to clean during flue flushing, the utility model provides a flue inlet flushing device for a desulfurization tower, which can improve the flushing efficiency and effect of the flue.

[0005] In order to solve the above problems, the technical solution of the utility model is as follows:

[0006] A flue inlet flushing device for a desulfurization tower includes a desulfurization tower. A flue is connected to the desulfurization tower. A liquid inlet pipe is arranged in the flue. The flushing member further includes a scrubbing member, which includes a first connecting ring and a first driving member. A rotating ring is rotatably sleeved on the outer ring of the first connecting ring. Tooth teeth are arranged on the inner ring of the rotating ring, and bristles in contact with the inner wall of the flue are arranged on the outer ring. The first driving member includes a housing, a sleeve and a cross bar. A housing is fixed on the inner ring of the first connecting ring. The two ends of the sleeve respectively penetrate and are rotatably connected to the left and right side plates of the housing. A gear sleeved and fixed outside the sleeve is arranged in the housing. The upper end of the gear penetrates the first connecting ring and meshes with the tooth teeth on the rotating ring. The cross bar passes through the sleeve, and both ends are fixedly connected to the flue through a first connecting plate. A spiral groove is arranged on the cross bar, and a driving rod extending into the spiral groove is arranged on the inner wall of the sleeve. A second driving member for driving the scrubbing member to move left or right is arranged on the flue.

[0007] Further, the liquid inlet pipe is an L-shaped pipe. The vertical section of the liquid inlet pipe penetrates the peripheral wall of the flue, and the horizontal section is coaxially arranged in the flue. The first connecting ring is sleeved outside the horizontal section of the liquid inlet pipe. A plurality of liquid outlet holes are evenly distributed on the horizontal section of the liquid inlet pipe.

[0008] Further, the free end of the horizontal section of the liquid inlet pipe is closed. A second connecting plate is connected between the free end of the horizontal section of the liquid inlet pipe and the inner wall of the flue. A second connecting ring is sleeved outside the horizontal section of the liquid inlet pipe. The second connecting ring and the first connecting ring are connected through the housing.

[0009] Further, an annular groove is provided on the outer ring of the first connecting ring, and the rotating ring is slidably arranged in the annular groove.

[0010] Further, a first corrugated pipe that is sleeved on the left part of the cross bar is connected between the left side of the housing and the first connecting plate on the left side, and a second corrugated pipe that is sleeved on the right part of the cross bar is connected between the right side of the housing and the first connecting plate on the right side.

[0011] Further, the second driving member includes a U-shaped plate, a rotating rod and a steel wire strand. The U-shaped plate is fixed to the upper end of the outer wall of the flue. A rotating rod is rotatably arranged between the front and rear inner surfaces of the U-shaped plate. The rotating rod is driven to rotate by a motor. The steel wire strand is wound around the rotating rod in a clockwise direction. One end of the steel wire strand movably penetrates through the left part of the circumferential wall of the flue and is connected to the upper end of the left side surface of the first connecting ring, and the other end of the steel wire strand movably penetrates through the right part of the circumferential wall of the flue and is connected to the upper end of the right side surface of the first connecting ring.

[0012] By the above technical solution, the beneficial effects of the present utility model are as follows:

[0013] When the motor drives the rotating rod to rotate in the present utility model, the rotating rod drives the steel wire strand to drive the first connecting ring to move leftward or rightward. When the first connecting ring moves leftward or rightward, it can drive the sleeve to move leftward or rightward. When the sleeve moves leftward or rightward, under the action of the spiral groove on the cross bar, the sleeve drives the gear to rotate. The gear meshes with the rotating ring to rotate forward or backward. Therefore, when the rotating ring rotates forward or backward, the bristles on the rotating ring, in cooperation with the water or cleaning agent on the inner wall of the flue, brush the inner wall of the flue, making it easier to clean the dirt on the inner wall of the flue and with high cleaning efficiency.

Since the driving rod 15 on the sleeve 10 is located in the spiral groove 14 and the cross bar where the spiral groove 14 is located is fixed, the driving rod 15 on the sleeve 10 can only move along the spiral groove 14. Therefore, while the sleeve 10 moves to the left along with the housing 9, it also rotates. The gear 12 rotates along with the sleeve 10. When the gear 12 rotates, it meshes with the teeth 7 on the rotating ring 6 and drives the rotating ring 6 to rotate. Therefore, while the rotating ring 6 moves to the left along with the first connecting ring 5, the brush bristles 8 on the rotating ring 6 brush the inner wall of the flue 2. Under the combined action of water or cleaning liquid on the inner wall of the flue, the stubbornly adhered dirt on the inner wall of the flue 2 can be cleaned; similarly, when the motor 26 drives the rotating rod 24 to rotate counterclockwise, it can drive the first connecting ring 5 to move to the right. When the first connecting ring 5 moves to the right, the sleeve 10 drives the gear 12 to rotate in the reverse direction, and the gear 12 meshes with the rotating ring 6 to rotate in the reverse direction, and the brush bristles on the rotating ring brush the dirt on the inner wall of the flue 2.
