[0002] In the field of boiler flue gas environmental protection treatment, desulfurization process is the key link in controlling sulfide emissions. In the current mainstream wet desulfurization technology, the spray mechanism in the reaction tower sprays desulfurizing agent through nozzles to contact the flue gas and remove sulfides through chemical reaction.

[0003] However, existing reaction towers have the following problems in actual operation: the flue gas rises too fast and the contact time with the spray liquid is too short, making it difficult for the chemical reaction between the desulfurizing agent and sulfides to be completed, thus affecting the desulfurization efficiency.

[0032] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1-8 A boiler environmental protection flue gas treatment reaction tower 1 includes a reaction tower 1. The reaction tower 1 has a spray mechanism installed inside for spraying desulfurizer to remove sulfides from the boiler flue gas. The spray mechanism includes a water tank 2, which is connected to a water pipe 3. A pump is installed on the water tank 2 to pump the desulfurizer inside the water tank 2 into the water pipe 3. A nozzle 6, arranged inside the reaction tower 1, is connected to the end of the water pipe 3 away from the water tank 2. The desulfurizer is sprayed out through the nozzle 6. The reaction tower 1 also has a turbulence-inducing mechanism inside.

[0034] The turbulence mechanism includes a transmission rod 16 and a reciprocating drive assembly for driving the transmission rod 16 to reciprocate.

[0035] The bottom surface of the transmission rod 16 is provided with a plurality of third hinge seats 26 arranged at equal intervals. The third hinge seat 26 is rotatably connected to a third rotating shaft 27. The third rotating shaft 27 is connected to a mounting rod 25 through a second connecting rod 28. The bottom surface of each mounting rod 25 is provided with a plurality of fan blades 31 arranged at equal intervals.

[0036] The reciprocating drive assembly slowly drives the transmission rod 16 to reciprocate, thereby driving the third hinge seat 26 to move. The third hinge seat 26 pushes the mounting rod 25 to rotate through the third rotating shaft 27 and the second connecting rod 28. The mounting rod 25 drives the fan blades 31 below to swing back and forth neatly, thereby blowing away the flue gas entering the reaction tower 1. The resulting airflow resistance will appropriately slow down the rising speed of the flue gas, prolong the contact time between the flue gas and the spray liquid, and make the chemical reaction more complete, resulting in a better desulfurization effect.

[0037] Furthermore, the interior of the reaction tower 1 is also equipped with a second mounting frame 9, located above the flow-turbulence mechanism. The inner side of the second mounting frame 9 is provided with several movable guide vanes 10 and fixed guide vanes 11.

[0038] The movable guide vane 10 is rotatably connected to the second mounting frame 9, and the fixed guide vane 11 is fixedly connected to the second mounting frame 9. The movable guide vane 10 and the fixed guide vane 11 are arranged in an alternating manner.

[0039] Each of the movable guide vanes 10 is provided with a connecting block 12 at its lower end, and a connecting rod 15 is provided on the bottom surface of the connecting block 12;

[0040] Furthermore, the top surface of the transmission rod 16 is provided with a plurality of first hinge seats 13 corresponding one-to-one with the first connecting rod 15, and the first connecting rod 15 is provided with a first rotating shaft 14, which is rotatably connected to the first connecting rod 15.

[0041] During the movement of the turbulence mechanism, that is, during the reciprocating motion of the transmission rod 16, the first hinge seat 13 is driven to move, which in turn drives the connecting block 12 to move through the first rotating shaft 14 and the first connecting rod 15. Ultimately, the movable guide vane 10 rotates around the second mounting frame 9 and cooperates with the fixed guide vane 11 to change the channel size. This increases the probability of flue gas colliding with the movable guide vane 10 and the fixed guide vane 11, thereby delaying the rate of flue gas rise and increasing the desulfurization effect.

[0042] Furthermore, a second hinge seat 23 is provided on the top surface of the mounting rod 25, and a second rotating shaft 24 is rotatably connected to the second hinge seat 23;

[0043] Furthermore, a fixed rod 22 is fixedly connected to the reaction tower 1, and the second rotating shaft 24 is set on the fixed rod 22, which can limit the installation rod 25 below, so that the installation rod 25 can reciprocate around the fixed rod 22.

[0044] Furthermore, the reciprocating drive assembly includes a mounting base 17, on which a reciprocating screw 18 is rotatably connected. A threaded block 19 is fitted on the outer side of the reciprocating screw 18 for use therewith. The threaded block 19 can move back and forth on the reciprocating screw 18 by rotating the reciprocating screw 18. The threaded block 19 is connected to the drive shaft 21 through a connecting bracket 20. The drive shaft 21 is fixedly connected to the transmission rod 16, thereby driving the transmission rod 16 to move back and forth.

[0045] The reciprocating drive assembly also includes a drive unit for driving the reciprocating screw 18 to rotate, preferably a servo motor.

[0046] Furthermore, the reaction tower 1 is provided with a flue gas inlet 4 near the bottom, through which boiler flue gas enters and can be transported by an external fan. The top of the reaction tower 1 is provided with a flue gas outlet 30, which is used to discharge the desulfurized flue gas and transfer it to the next process for treatment until it meets the emission standards.

[0047] Furthermore, the reaction tower 1 is also provided with a maintenance port 5 to facilitate its maintenance and repair.

[0048] Furthermore, the reaction tower 1 is provided with a dustproof shell 29 arranged on the outside of the reciprocating drive assembly, which can reduce the erosion of dust.

[0049] Furthermore, both the movable guide vane 10 and the fixed guide vane 11 are wavy in shape, which can increase the collision frequency with the flue gas.

[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
