The operation of the bypass flue gas removal device 10 for semi-dry desulfurization is described below (see fig. 1 to 7):
when the absorption tower normally operates, the bypass damper plate 200 is in a closed state, and the bypass smoke exhaust channel 700 is blocked by the bypass damper plate 200; when the bypass door stopper 200 is closed, the first convex column 310 and the second convex column 320 of the connecting block 300 are both accommodated in the opening buffer guide groove 810; at this time, the first boss 310 is separated from the other end of the opening buffer spring 410, and the second boss 320 is separated from the guide post 540; the bypass damper plate 200 is pressed on the support boss 710;
when the absorption tower is abnormal and can not normally operate, the smoke discharged from the main path smoke outlet 120 can not be smoothly absorbed by the absorption tower and then is discharged through a chimney, and the smoke generated by the boiler is continuously input into the main path smoke exhaust channel 600, so that the smoke in the main path smoke exhaust channel 600 is gathered, and the pressure in the main path smoke exhaust channel 600 is continuously increased; along with the continuous rising of the smoke pressure in the main smoke exhaust channel 600, the smoke pressure borne by the bypass damper plate 200 is continuously increased; when the smoke pressure increases enough to overcome the gravity of the bypass damper plate 200 but has not yet reached the predetermined threshold, the smoke pressure pushes the bypass damper plate 200 to rise along the bypass smoke evacuation channel 700; meanwhile, the first convex column 310 and the second convex column 320 both move upwards along the opening buffer guide groove 810;
when the first protruding column 310 moves upward to contact with the other end of the opening buffer spring 410, the smoke pressure needs to be increased enough to overcome the gravity of the bypass damper plate 200 and the elastic force of the opening buffer spring 410 but still does not reach a predetermined threshold value, so that the bypass damper plate 200 can be continuously pushed to ascend along the bypass smoke exhaust channel 700; along with the continuous increase of the smoke pressure, the bypass damper plate 200 continuously rises along the bypass smoke exhaust channel 700, and simultaneously the first convex column 310 and the second convex column 320 both move upwards along the opening buffer guide groove 810;
when the smoke pressure reaches the threshold value, the first convex column 310 moves up to abut against the buffering limit boss 811, and the second convex column 320 rises to the connection position of the main smoke exhaust channel 600 and the bypass smoke exhaust channel 700; if the smoke pressure is further increased, that is, the smoke pressure exceeds a threshold value, the connecting block 300 starts to rotate around the first convex column 310, and the connecting block 300 drives the bypass damper plate 200 to rotate together; the bypass smoke exhaust channel 700 is gradually opened in the rotation process of the bypass damper plate 200, so that smoke is discharged from the bypass smoke exhaust channel 700 to a chimney and then directly discharged to the atmosphere from the chimney; meanwhile, the second boss 320 moves upward along the opening degree adjustment guide slot 820 and approaches the guide post 540;
when the second protruding column 320 contacts the guiding column 540, the smoke pressure needs to be increased continuously to overcome the gravity of the bypass damper plate 200 and the elastic force of the opening degree adjusting spring 510, so as to further open the bypass damper plate 200 to increase the smoke discharge speed; as the smoke pressure continues to increase, the bypass damper plate 200 continues to rotate and open, and the second protruding column 320 and the guiding column 540 continue to move upwards towards the opening limiting boss 821 and continuously compress the opening adjusting spring 510; when the guide post 540 moves upward to abut against the opening limit boss 821, the bypass damper plate 200 is opened to the maximum, that is, the smoke discharge speed reaches the maximum;
in the practical application process, the bearing capacities of different application occasions on the smoke pressure are different, or the bearing capacities of different smoke systems on the smoke pressure are different; therefore, the threshold value of the bypass smoke exhaust device 10 and the opening sensitivity of the bypass damper plate 200 thereof need to be adaptively adjusted according to different application occasions or different smoke systems;
if the threshold corresponding to the opening of the bypass door stopper 200 needs to be changed, the opening buffer ratchet 440 can be rotated, and the opening buffer ratchet 440 rotates to drive the opening adjusting gear 520 to rotate, so that the opening adjusting gear 520 moves upwards or downwards along the opening buffer screw 430, and further the opening adjusting gear 520 drives the opening buffer spring 410 to move upwards or downwards along the opening buffer screw 430; if the opening buffer spring 410 moves upwards along the opening buffer screw 430, the first convex column 310 can move upwards to abut against the buffer limiting boss 811 by requiring a smaller smoke pressure (i.e. the threshold of the bypass smoke exhaust device 10 is reduced); if the opening buffer spring 410 moves downwards along the opening buffer screw 430, a larger smoke pressure is required to move the first convex column 310 upwards to abut against the buffer limiting boss 811 (i.e. the threshold of the bypass smoke exhaust device 10 is increased);
if the opening sensitivity of the bypass damper plate 200 needs to be changed, the opening adjusting ratchet 550 can be rotated, and the opening adjusting ratchet 550 drives the opening adjusting gear 520 to rotate when rotating, so that the opening adjusting gear 520 moves up or down along the opening adjusting screw 530; if the opening adjusting gear 520 moves upwards along the opening adjusting screw 530, the bypass damper plate 200 can be opened to a corresponding degree by requiring a small smoke pressure; if the opening adjusting gear 520 moves down along the opening adjusting screw 530, the bypass damper plate 200 needs to be opened to a corresponding degree by a large smoke pressure;
the bypass smoke exhaust device 10 provided by the invention is only opened when the smoke pressure exceeds a preset threshold value, and the bypass damper plate 200 is opened; the opening degree of the bypass damper plate 200 is adjusted in a real-time self-adaptive manner according to the smoke pressure; the pollution to the air is minimized while the safe production effect is ensured;
moreover, the bypass smoke exhaust device 10 disclosed by the invention can flexibly adjust the smoke pressure threshold value corresponding to the opening of the bypass damper plate 200 and the opening sensitivity of the bypass damper plate 200 according to different application occasions or different applied smoke systems, so that the bypass smoke exhaust device 10 disclosed by the invention has good adaptability and high flexibility;
furthermore, the bypass smoke exhaust device 10 disclosed by the invention has the advantages that the opening degree of the bypass damper plate 200 is controlled by mechanically sensing the smoke pressure and directly controlling the smoke pressure, so that the precision is high and the reliability is good.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
