Description

Technical Field

[0001] The utility model relates to the technical field of flue gas desulfurization towers, and specifically, to a spraying assembly of a flue gas desulfurization tower. Background Art

[0002] A desulfurization tower is a tower device for desulfurizing industrial waste gas, which is widely used in flue gas desulfurization in the domestic coal industry. The desulfurization tower can prevent the discharge of sulfur-containing flue gas and cause air pollution. The gas after desulfurization treatment by the desulfurization tower is harmless to the environment and is relatively environmentally friendly.

[0003] After retrieval, the utility model patent with the publication number of CN220657030U discloses a flue gas desulfurization tower, including a bottom plate and a desulfurization tower body. The desulfurization tower body is installed on the surface of the bottom plate. The inside of the desulfurization tower body is connected to an intake pipe, and the inside of the desulfurization tower body is connected to an exhaust pipe. A collection box is fixedly connected inside the desulfurization tower body; the first motor in the rotating device drives the connecting column to rotate, the connecting column drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the hollow column to rotate, the hollow column drives the hollow plate to rotate, the hollow plate slides in the desulfurization tower body, and the hollow plate drives the second water pipe and the nozzle to rotate, so that the nozzle sprays desulfurization liquid, and the spraying area of the nozzle is increased, the spraying is comprehensive, and the situation that the desulfurization tower does not desulfurize the flue gas thoroughly will not occur.

[0004] However, the above patent still has the following deficiencies: the position of the nozzle on the second water pipe is fixed. When the second water pipe and the nozzle rotate, the nozzle can only rotate on a specific circumference with the hollow column as the center. Therefore, the nozzle can only spray water below this circumference, and the water spraying effect between the two nozzles is poor; in addition, since the position where the flue gas enters the tower body is fixed and the direction of the fan blades blowing the flue gas is fixed, the effect of dispersing the flue gas is poor. For this reason, we propose a spraying assembly of a flue gas desulfurization tower. Summary of the Utility Model

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] (1) In the present utility model, the desulfurizing agent is sprayed by the nozzle through the cooperation of the liquid inlet pipe, the rotary joint, the hollow column, the liquid distribution box, the hose and the liquid distribution movable box. In addition, the cooperation of the servo motor, the first bevel gear and the second bevel gear drives the liquid distribution box, the rotating disc and the third bevel gear to rotate circumferentially. The cooperation between the third bevel gear and the internal helical ring drives the reciprocating lead screw to rotate. The threaded cooperation between the reciprocating lead screw and the liquid distribution movable box drives the liquid distribution movable box to move along the axial direction of the reciprocating lead screw, so that the nozzle rotates circumferentially and moves horizontally at the same time, ensuring that the nozzle can spray the entire bottom area of the rotating disc and ensuring the desulfurization effect of the contact between the desulfurization liquid and the flue gas.

[0015] (2) In the present utility model, through the combined use of the rotating rod and the stirring blades, when the rotating disc rotates, a plurality of stirring blades are synchronously driven to rotate.

The falling desulfurization liquid can also be dispersed, ensuring full contact between the flue gas and the desulfurization liquid and improving the working quality of the spraying assembly of the flue gas desulfurization tower.

[0028] In this embodiment, the stirring blades 16 are used to disperse the flue gas entering the inner cavity of the tower body 1 to ensure that the desulfurization liquid contacts the flue gas evenly after being sprayed.

[0029] For details, please refer to Figure 1 and Figure 2 The driving mechanism 4 includes a servo motor 17 fixedly mounted on the outside of the tower body 1. The output shaft of the servo motor 17 extends to the inner cavity of the tower body 1 and is fixedly connected to a transmission rod 18.
