All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 3, the invention provides a spray system of a desulfurization absorption tower, which comprises an absorption tower 1, wherein a spray pipeline 2 parallel to a horizontal plane is fixedly connected in the absorption tower 1, a plurality of conical nozzles 3 for spraying gypsum slurry upwards in a vertical direction are arranged on the spray pipeline 2 at equal intervals along the axis of the spray pipeline 2, an elastic connecting piece 4 which elastically deforms in the vertical direction is also arranged on the spray pipeline 2, and a leaching net surface 5 is arranged on the elastic connecting piece 4;
wherein, the horizontal section of the conical nozzle 3 is reduced in diameter along the vertical direction, and the leaching net surface 5 is used for adhering the gypsum slurry sprayed by the conical nozzle 3 and synchronously reciprocating with the elastic connecting piece 4 along the vertical direction under the impact of the gypsum slurry.
When the spraying device is used, flue gas moves along the horizontal direction, gypsum slurry is pumped into the spraying pipeline 2 through the pump body and sprayed into the absorption tower 1 through the conical nozzle 3, and harmful gases such as sulfur dioxide in the flue gas are absorbed through the contact of the sprayed gypsum slurry and the flue gas, so that the harm to the natural environment is avoided.
And the conical nozzles 3 are big-end-up, so that the blocking probability is reduced, and the plurality of conical nozzles 3 are arranged on the spray pipeline 2, so that the problem that the blockage of the spray pipeline 2 influences the removal of the harmful gas in the flue gas due to the blockage of the single conical nozzle 3 is avoided.
And the conical nozzle 3 upwards sprays the gypsum slurry along the vertical direction and is mutually perpendicular to the movement path of the flue gas, so that the gypsum slurry upwards moves for a certain distance and then falls under the action of gravity, the contact time of the gypsum slurry and the flue gas in the air is prolonged, the gypsum slurry is more fully contacted with the flue gas, the removal rate of the gypsum slurry on harmful gases such as sulfur dioxide in the flue gas is improved, the amount of the gypsum slurry which is not contacted with the flue gas is reduced, and the waste of the gypsum slurry is reduced.
Secondly, the elution net surface 5 is contacted with the gypsum slurry sprayed upwards by the conical nozzle 3, so that part of the gypsum slurry is attached to the elution net surface 5, and the flue gas is fully contacted with the gypsum slurry attached to the elution net surface 5 when passing through the elution net surface 5, thereby further improving the contact time of the gypsum slurry and the flue gas, further improving the absorption rate of harmful gases such as sulfur dioxide in the flue gas, and reducing the content of the harmful gases such as sulfur dioxide in the flue gas.
The gypsum slurry which is pumped by the pump body and sprayed by the conical nozzle 3 has certain impact force when contacting with the leaching net surface 5, so that the leaching net surface 5 drives the elastic connecting piece 4 to move along the vertical direction under the impact of the gypsum slurry, and the elastic connecting piece 4 elastically deforms in the vertical direction, thereby driving the leaching net surface 5 to reciprocate along the vertical direction under the elastic action of the elastic connecting piece 4.
The gypsum slurry attached to the leaching net surface 5 is separated from the leaching net surface 5 under the reciprocating motion of the leaching net surface 5 after contacting with the flue gas, so that the gypsum slurry which is in contact reaction with the flue gas is separated from the leaching net surface 5, and new gypsum slurry sprayed by the conical nozzle 3 is attached to the leaching net surface 5 again to be contacted with the flue gas, so that the sufficient contact reaction of the gypsum slurry and the flue gas is ensured, the absorption rate of the gypsum slurry on harmful gases such as sulfur dioxide in the flue gas is improved, and the problem that the leaching net surface 5 is blocked due to the fact that the gypsum slurry is attached to the leaching net surface 5 is solved.
The elastic connecting piece 4 comprises a connecting seat 401 arranged on the spray pipeline 2, a sliding slot 402 is arranged on the connecting seat 401 along the vertical direction, a sliding connecting plate 404 moving along the vertical direction is connected in the sliding slot 402 in a sliding mode through a connecting spring 403, and the leaching net face 5 is arranged at the top of the sliding connecting plate 404.
When the elastic connecting piece 4 is used, the washing screen surface 5 is arranged on the sliding connecting plate 404, and when the washing screen surface 5 is impacted by gypsum slurry, the sliding connecting plate 404 is driven to slide up and down along the sliding slot 402, and meanwhile, the connecting spring 403 is compressed in the vertical direction to deform.
When the leaching net surface 5 moves to the highest point or the lowest point under the action of the elastic force of the connecting spring 403, the leaching net surface 5 moves reversely under the action of the elastic force of the connecting spring 403 and the combined force of the impact force of the gypsum slurry, so that the sliding connecting plate 404 and the leaching net surface 5 reciprocate along the vertical direction to shake off the attached gypsum slurry, the gypsum slurry attached to the leaching net surface 5 is not completely contacted and reacted with flue gas, and the gypsum slurry is prevented from blocking the leaching net surface 5.
The connecting block 401 is used to provide support for the installation and movement of the slide connection plate 404.
An annular groove 405 for installing a connecting spring 403 is arranged on the inner side wall of the sliding slot 402, and a plurality of strip-shaped sliding grooves 406 which are symmetrical around the center line of the sliding slot 402 are jointly arranged on the inner side wall of the annular groove 403 and the inner side wall of the sliding slot 402;
the surface of the sliding connection plate 404 is provided with a plurality of bar-shaped block groups which are slidably connected with the corresponding bar-shaped sliding grooves 406, each bar-shaped block group comprises two stoppers 407 arranged along the length direction of the bar-shaped groove 406, and the distance between the two stoppers 407 is the same as the length of the connection spring 403.
When the sliding connection plate 404 moves upward along the vertical direction, the stopper 407 with a lower height slides upward along the strip-shaped sliding groove 406 to compress the connection spring 403 in the annular groove 405, and when the sliding connection plate 404 moves to the highest point, the stopper 407 moves downward along the vertical direction under the combined force of the connection spring 404 and the impact force of the gypsum slurry, and in the process, one end of the connection spring 404 is in contact with the stopper 407, and the other end of the connection spring is in contact with the side wall of the annular groove 405.
When the connecting spring 404 returns to the original length in the downward movement process, the downward movement is continued, and at the moment, the stopper 407 with the higher height slides downwards along the strip-shaped sliding chute 406 to jointly compress the connecting spring 403 in the annular groove 405 until the movement speed of the sliding connecting plate 404 is zero, so that the reciprocating movement not only ensures that gypsum slurry attached to the washing net surface 5 is not completely in contact reaction with the flue gas, but also avoids the gypsum slurry from blocking the washing net surface 5.
In the process of reciprocating the sliding connecting plate 404, because the distance between the two stoppers 407 is the same as the length of the connecting spring 403, the two ends of the connecting spring 403 are always in contact with the side wall of the annular groove 405 and the stoppers 407, i.e., the connecting spring 403 can always improve the elasticity of the sliding connecting plate 404, thereby ensuring that the sliding connecting plate 404 can reciprocate in the vertical direction.

The connection seat 401 is provided with a shower-proof cover 411 covering the outside of the sliding connection plate 404, and the shower-proof cover 411 is provided with a through groove 412 for the first connection plate 408 to move up and down along the vertical direction.
The anti-drenching cover 411 prevents the sprayed gypsum slurry from directly entering the sliding slot 402, so that the relative movement between the second connecting plate 410 and the sliding slot 402 is in failure, and the connecting spring 403 cannot be deformed normally.
By providing the through-slot 412 such that the first link plate 408 moves in the vertical direction through the through-slot 412, interference with the movement of the slide link plate 404 is avoided.

The through-slit 416 is provided for the drain pipe 415 to discharge the gypsum slurry therethrough without interference with the drain pipe 415 when the drain pipe 415 moves up and down following the first connection plate 408.
Further, the strip-shaped through groove 416 is formed in the side wall of the shower protection cover 411, which is parallel to the axis of the shower pipe 2 and parallel to the vertical plane, so that gypsum slurry sprayed by the conical nozzle 3 is prevented from entering the inside of the shower protection cover 411 through the strip-shaped through groove 416.
