The other end of the bypass damper plate 30 is provided with a roller 310, and the other end of the bypass damper plate 30 abuts against or is separated from the docking guide 411 through the roller 310. The jerk-motion smoke evacuation device 10 further includes a fixed guide plate 80 fixedly connected to the bypass smoke evacuation path 70, the docking guide 411 is further docked with or separated from the fixed guide plate 80, and the other end of the bypass damper plate 30 is docked with or separated from the fixed guide plate 80 by the roller 310.
As shown in fig. 5, the sleeve portion 412 has an escape groove 413, and the pressure-sensitive column 430 is connected to a bottom wall of the escape groove 413 by a pressure-sensitive spring 420. The pressure-sensitive spring 420 provides an elastic force to the pressure-sensitive column 430, so that the pressure-sensitive column 430 has a tendency to protrude out of the avoiding groove 413. The pressure-sensitive limiting member 440 has a limiting groove 441, and the pressure-sensitive column 430 is abutted against or separated from the limiting groove 441.
As shown in fig. 6, specifically, one end of the fixed guide plate 80 near the docking guide 411 is provided with a docking bay 810, and the docking guide 411 is pressed against the docking bay 810 or separated from the docking bay 810; when the docking guide portion 411 is docked with the fixed guide plate 80, the docking guide portion 411 and the fixed guide plate 80 cooperate to form a smooth guide surface 90 (as shown in fig. 8). In the present embodiment, the docking guide 411 has a plate-shaped structure.
As shown in fig. 6 and 8, specifically, a closed block 710 is disposed at an end of the bypass smoke evacuation channel 70 close to the main smoke evacuation channel 60, and an end of the bypass damper plate 30 abuts against or is separated from the closed block 710.

In this embodiment, the closure blocker 710 is disposed opposite the anti-reverse blocker 720.
As shown in fig. 7 and 8, the three-way smoke exhaust casing 20 further has a main smoke inlet 210, a main smoke outlet 220 and a bypass smoke outlet 230. In practical application, the main flue inlet 210 is externally connected with a boiler flue gas inlet channel, the main flue outlet 220 is communicated with a flue gas inlet channel of the absorption tower, and the bypass flue outlet 230 is directly communicated with a chimney.
The operation of the jerky motion extractor 10 that achieves bypass flapper door opening by sensing the flue gas pressure is described below (please refer to fig. 1-8):
when the absorption tower normally operates, the jerk fume extractor 10 is in a closed state, and the bypass damper door is closed to block the bypass fume channel 70; when the bypass damper door is closed, the rotational connection point of the jerk link 510 and the bypass smoke evacuation path 70 is located to the right of the center axis of the jerk spring 520 (as shown in fig. 3 and 4); at this time, the snap spring 520 provides a torque force to the bypass damper plate 30 through the snap link 510, so that the bypass damper plate has a tendency to rotate counterclockwise (as shown in fig. 3); however, the closing blocking block 710 and the anti-reverse blocking block 720 respectively abut against two ends of the bypass door stopper 30, so as to prevent the bypass door stopper 30 from rotating counterclockwise, thereby ensuring that the bypass door stopper 30 is kept in a stable closing state, i.e. the bypass door stopper 30 is kept in a balanced state;
when the absorption tower is abnormal and can not normally operate, the smoke discharged from the main path smoke outlet 220 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 60, so that the smoke in the main path smoke exhaust channel 60 is gathered, and the pressure in the main path smoke exhaust channel 60 is continuously increased; as the smoke pressure in the main smoke exhaust channel 60 continuously rises, the smoke pressure borne by the bypass damper plate 30 continuously increases, but the smoke pressure does not reach a predetermined threshold value at this time, the smoke pressure applied to the bypass damper plate 30 is not enough to overcome the elastic force of the jerk spring 520 for rotating the jerk link 510 in the counterclockwise direction, and the bypass damper plate 30 is still kept in a closed state;
referring to fig. 7 and 8, when the smoke pressure in the main smoke exhaust channel 60 increases to a threshold value, the smoke pressure applied to the bypass damper plate 30 exceeds the elastic force of the snap spring 520 to rotate the snap link 510 counterclockwise; at this time, the smoke pressure applied to the bypass damper plate 30 overcomes the elastic force of the jerk spring 520 for rotating the jerk link 510 counterclockwise, and at the same time, indirectly applies a force to the pressure-sensitive spring 420 to compress and deform the pressure-sensitive spring 420, so that the bypass damper plate 30 starts to rotate clockwise (as shown in fig. 8); in the process, the bypass damper plate 30 is continuously pressed on the connection guide portion 411 through the roller 310 and the connection guide portion 411 rotates clockwise along with the bypass damper plate 30, and the bypass damper plate 30 also drives the jerk link 510 to rotate clockwise; while the docking guide 411 rotates clockwise, the pressure-sensitive column 430 continuously abuts against the limiting groove 441 and rotates along the limiting groove 441; in the process, the pressure-sensitive column 430 continuously retracts into the avoiding groove 413, and the pressure-sensitive spring 420 continuously compresses; when the docking guide 411 rotates clockwise by a certain angle, the pressure-sensitive column 430 is separated from the limiting groove 441; at the moment when the pressure-sensitive column 430 is disengaged from the limiting groove 441, the pressure-sensitive link 410 is disengaged from the limit of the pressure-sensitive limiting piece 440 and enters a free state; the jerking link 510 continues to rotate under the continued action of the smoke pressure, and when the rotational connection point of the jerking link 510 and the bypass smoke evacuation channel 70 is located at the left side of the central axis of the jerking spring 520 (as shown in fig. 8), the jerking spring 520 has an elastic restoring force that drives the jerking link 510 to rapidly rotate clockwise (the bypass damper plate 30 enters the jerked open state);
as shown in fig. 7 and 8, the jerk opening process of the bypass damper plate 30 includes a pre-docking stage and a post-docking stage; in the pre-connection stage, under the action of the elastic restoring force of the snap spring 520, the snap link 510 drives the bypass damper plate 30 to rotate clockwise; when the bypass damper plate 30 rotates clockwise, the roller 310 continuously presses the connection guide portion 411, so that the connection guide portion 411 rotates clockwise until the connection guide portion 411 is connected to the fixed guide plate 80;
as shown in fig. 7 and 8, in the post-connection stage, under the elastic restoring force of the snap spring 520, the snap link 510 continues to drive the bypass damper plate 30 to rotate clockwise; however, at the same time, the roller 310 continuously travels along the docking guide 411 and the fixed guide plate 80 along the docking guide 411 (i.e. the roller 310 travels along the smooth guide surface 90) until the bypass damper plate 30 is parallel to and closely attached to the inner wall of the bypass smoke evacuation channel 70; when the bypass damper plate 30 is parallel to and clings to the inner wall of the bypass smoke exhaust channel 70, the bypass damper plate 30 is completely opened, and the main smoke exhaust channel 60 is completely communicated with the bypass smoke exhaust channel 70;
when the bypass damper plate 30 is completely opened, the smoke in the main path smoke exhaust channel 60 rapidly enters the bypass smoke exhaust channel 70, enters the chimney through the bypass smoke exhaust channel 70 and is directly discharged from the chimney;
according to the jerky smoke exhaust device 10 disclosed by the invention, on one hand, the bypass damper plate 30 is opened jerkily only when the smoke pressure reaches a preset threshold value, so that smoke is exhausted urgently, and the stable operation of the whole smoke system is ensured; on the other hand, when the smoke pressure reaches the threshold value through the jerking mechanism 50, the bypass damper plate 30 is quickly and completely opened, so that the smoke is quickly discharged;
the jerky smoke exhaust device 10 of the present invention is normally closed in a smoke system, and is opened only when the absorption tower fails; while the jerky smoke extractor 10 is rarely usable, it is certainly necessary for safe production operations; if the bypass damper plate 30 of the jerky smoke exhaust device 10 is triggered to be opened, the jerky smoke exhaust device 10 is taken down from the smoke system and reset and then installed again for use after the failure is relieved and before the smoke system is restarted.
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 various changes and modifications can be made by those skilled in the art without departing from the spirit of the invention, and these changes and modifications are all within the scope of the invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
