DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below by referring to the drawings.

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below by referring to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without any creative labor fall within the scope of protection of the present application.

[0032] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application.

In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0033] In the related art, the probability of wear is reduced by increasing the hardness of the material of the easily-worn part. However, the arrangement of the flue gas before entering the circulating fluidized bed is different, and the airflow deviation also changes with the arrangement and working condition. In addition, the composition of the flue gas dust is also different due to the source of the front-end fuel, and the high hardness of the dust particles and the high flow rate also cause wear.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 is a structural schematic diagram of a flue gas treatment equipment provided by an embodiment of the present application, Figure 2 is Figure 1 a top view of a lower adjusting device in the flue gas treatment equipment, Figure 3 is Figure 1 a top view of a lower adjusting device in the flue gas treatment equipment. The flue gas treatment equipment can include a flue 100, a reaction tower 200, a lower adjusting device 300, and an upper adjusting device 400.

[0035] The flue 100 and the reaction tower 200 in the flue gas treatment equipment can be connected to each other, and the outlet a1 of the flue 100 can be in communication with the inlet b1 of the reaction tower 200, that is, the outlet a1 of the flue 100 can be connected to the inlet b1 of the reaction tower 200. Here, flue gas can enter the flue 100 from the inlet of the flue 100, and enter the reaction tower 200 from the outlet a1 of the flue 100 and the inlet b1 of the reaction tower 200.

[0036] The lower adjusting device 300 in the flue gas treatment equipment can be fixed at the inlet b1 of the reaction tower 200, and the lower adjusting device 300 can include a plurality of first rotating shafts 301 arranged in a first direction f1 and a plurality of first blades 302 arranged in the first direction f1. The plurality of first rotating shafts 301 and the plurality of first blades 302 can be fixedly connected one by one, the extension direction of the first rotating shaft 301 and the extension direction of the first blade 302 can be parallel to the second direction f2, each first rotating shaft 301 can be rotationally connected to the reaction tower 200, and one end of the first rotating shaft 301 can extend out of the reaction tower 200. Here, the first direction f1 can be arranged perpendicular to the second direction f2, and the first direction f1 and the second direction f2 can be perpendicular to the central axis of the reaction tower 200.

[0037] The upper adjusting device 400 can be fixed on the side of the lower adjusting device 300 away from the inlet b1 of the reaction tower 200, and the upper adjusting device 400 can include a plurality of second rotating shafts 401 arranged in the second direction f2 and a plurality of second blades 402 arranged in the second direction f2, and the plurality of second rotating shafts 401 can be fixedly connected with the plurality of second blades 402 one by one. The extension direction of the second rotating shaft 401 and the extension direction of the second blade 402 can both be parallel to the first direction f1, each second rotating shaft 401 can be rotationally connected with the reaction tower 200, and one end of the second rotating shaft 401 can extend out of the reaction tower 200. The side wall of the reaction tower 200 can have a material inlet b2 in communication with the reaction tower 200, and the material inlet b2 can be located on the side of the upper adjusting device 400 away from the inlet b1 of the reaction tower 200. It should be noted that the lower adjusting device 300 and the upper adjusting device 400 can both be located in the reaction tower 200.

[0038] Among them, the first rotating shaft 301 can be used to drive the corresponding first blade 302 to rotate by a first target angle, and the second rotating shaft 401 can be used to drive the corresponding second blade 402 to rotate by a second target angle.

[0039] For example, the first rotating shaft 301 can be fixedly connected with the central region of the first blade 302, and the second rotating shaft 401 can be fixedly connected with the central region of the second blade 402.

[0040] In the embodiments of the present application, when the initial wear of the side wall of the reaction tower 200 occurs due to the deflection of the flue gas, according to the position of the wear of the side wall of the reaction tower 200, the rotation target angle of the first blade 302 is adjusted by rotating the first rotating shaft 301 and / or the rotation target angle of the second blade 402 is adjusted by rotating the second rotating shaft 401, so as to change the deflection phenomenon of the flue gas in the first direction f1 and / or the second direction f2. That is, the deflection of the flue gas in each direction is corrected, which prevents the flue gas dust and the material from causing severe wear of the reaction tower wall plate, and also avoids the need for shutdown maintenance of the equipment, which is high in safety and low in cost. It should be noted that when the angle of one of the first blade 302 and the second blade 402 is adjusted, the plurality of blades in the other blade can be in a horizontal state.

Figure 1As shown, when initial wear occurs at side A of the reaction tower 200, the first rotating shaft 301 can be rotated in the clockwise direction, so that the flue gas flows along the central region of the reaction tower 200 after passing through the plurality of first vanes 302.

[0042] In summary, the embodiment of the present application provides a flue gas treatment device, which can include a flue, a reaction tower, a lower adjusting device, and an upper adjusting device. When initial wear occurs on the side wall of the reaction tower due to the deflection of the flue gas, the rotation angle of the first vane is adjusted by rotating the first rotating shaft according to the position of the wear on the side wall of the reaction tower, and / or the rotation angle of the second vane is adjusted by rotating the second rotating shaft, so as to change the deflection phenomenon of the flue gas in the first direction and / or the second direction. That is, the deflection of the flue gas in each direction is corrected, preventing the flue gas dust and material from causing severe wear on the wall plate of the reaction tower, and without the need for shutdown maintenance of the equipment, the safety degree is high and the cost is low. It should be noted that after the angle of one of the first vane and the second vane is adjusted, the plurality of vanes in the other vane are in a horizontal state. When there is no deflection phenomenon or the deflection phenomenon is small, the plurality of first vanes and the plurality of second vanes are in a horizontal state, and the plurality of first vanes and the plurality of second vanes arranged in layers can form a grid, which can have a certain rectification effect on the flue gas, so as to ensure that the impact on the side wall of the reaction tower is small.

[0043] Optionally, please refer to Figure 4 , Figure 5 and Figure 6 , Figure 4 is a structural schematic diagram of another flue gas treatment device provided by the embodiment of the present application, Figure 5 is a top view of another lower adjusting device provided by the embodiment of the present application, Figure 6 is a top view of another upper adjusting device provided by the embodiment of the present application. The lower adjusting device 300 in the flue gas treatment device can further include a first annular support 303, which can be tightly connected with the inner side wall of the reaction tower 200, and the plurality of first vanes 302 can be located in the area surrounded by the first annular support 303.

In this way, the first rotating shaft 301 and the plurality of first vanes 302 can be stably supported by the first annular support 303, and the second rotating shaft 401 and the plurality of second vanes 402 can be stably supported by the second annular support 403.

[0044] In the embodiment of the present application, the sidewall of the reaction tower 200 can have a first connecting hole (not shown in the figure) rotationally connected with the first rotating shaft 301, and a second connecting hole rotationally connected with the second rotating shaft 401. The lower adjusting device in the flue gas treatment equipment can further include a first annular sealing member (not shown in the figure) fixed on the inner sidewall of the first connecting hole, and the upper adjusting device can further include a second annular sealing member fixed on the inner sidewall of the second connecting hole. In this way, by fixing the first annular sealing member on the inner sidewall of the first connecting hole, the first annular sealing member is sleeved on the first rotating shaft 301, the first connecting hole can be effectively sealed to prevent flue gas from leaking out. By fixing the second annular sealing member on the inner sidewall of the second connecting hole, the second annular sealing member is sleeved on the second rotating shaft 401, the second connecting hole can be effectively sealed to prevent flue gas from leaking out.

The upper adjusting device 400 can further include a second hand wheel 404 connected with one end of the second rotating shaft 401, and the second hand wheel 404 can be located outside the reaction tower 200. In this way, the first hand wheel 304 facilitates the operator to drive the first rotating shaft 301 to rotate, and the second hand wheel 404 facilitates the operator to drive the second rotating shaft 401 to rotate.

[0046] For example, the first hand wheel 304 can have a first hand wheel fixing member (not shown in the figure), and after the first rotating shaft 301 drives the first blade 302 to rotate by a first target angle, the first hand wheel fixing member can be clamped to the outer side of the reaction tower 200. In this way, the first hand wheel 304 can be prevented from being undesirably rotated by being accidentally touched. The second hand wheel 404 can have a second hand wheel fixing member (not shown in the figure), and after the second rotating shaft 401 drives the corresponding second blade 402 to rotate by a second target angle, the second hand wheel fixing member can be clamped to the outer side of the reaction tower 200. In this way, the second hand wheel 404 can be prevented from being undesirably rotated by being accidentally touched.

[0047] In the embodiment of the present application, as shown in Figure 4As shown, the flue gas treatment device further comprises a plurality of sets of detection auxiliary members 500 fixed on the outer side of the reaction tower 200, which can be located on the side of the material inlet b2 away from the inlet b1 of the reaction tower 200. Each detection auxiliary member 500 can have a cavity and an opening c1 communicating with the cavity. The plurality of sets of detection auxiliary members 500 can be distributed in an axial array along the reaction tower 200, and each set of detection auxiliary members 500 comprises a plurality of detection auxiliary members distributed in a circumferential direction of the reaction tower. The region of the outer side of the reaction tower 200 corresponding to the detection auxiliary member 500 is exposed by the opening c1 of the detection auxiliary member, and the thickness gauge detects the thickness of the region of the outer side of the reaction tower 200 exposed by the opening c1 of the detection auxiliary member 500 through the opening c1 of the detection auxiliary member 500. In this way, when detecting the thickness of the side wall of the reaction tower 200, the region of the side wall of the reaction tower 200 corresponding to the opening c1 of the detection auxiliary member 500 does not need to be provided with a heat preservation layer, i.e. the entire heat preservation layer on the outer side of the reaction tower 200 does not need to be removed during detection, and the thickness of the side wall of the reaction tower 200 in the region can be measured by the thickness gauge through the opening of the detection auxiliary member, and then the worn region of the reaction tower can be determined according to the measured thickness, and the flue gas can be corrected by the first adjusting device 300 and / or the second adjusting device 400 in time. Here, the thickness gauge can be an ultrasonic thickness gauge.

[0048] In the present application, the plurality of detection auxiliary members 500 in each set of detection auxiliary members 500 can be distributed at equal intervals. It should be noted that more detection auxiliary members 500 can be arranged in the region of the reaction tower 200 where the wear is more obvious according to the actual working condition.

[0049] In summary, the flue gas treatment device provided by the embodiments of the present application can comprise a flue, a reaction tower, a lower adjusting device and an upper adjusting device. When the flue gas flow deviation causes the initial wear of the side wall of the reaction tower, the rotation angle of the first vane is adjusted by rotating the first rotating shaft and / or the rotation angle of the second vane is adjusted by rotating the second rotating shaft according to the position of the wear of the side wall of the reaction tower, so as to change the flow deviation of the flue gas in the first direction and / or the second direction. That is, the flow deviation of the flue gas in each direction is corrected, which prevents the flue gas dust and the material from causing severe wear of the wall plate of the reaction tower, and the equipment does not need to be shut down for maintenance, which is safe and low in cost. It should be noted that when the angle of one of the first vane and the second vane is adjusted, the plurality of vanes in the other vane are in a horizontal state. When there is no flow deviation of the flue gas or the flow deviation is small, the plurality of first vanes and the plurality of second vanes are in a horizontal state, and the plurality of first vanes and the plurality of second vanes arranged in layers can form a grid, which can produce a certain flow effect on the flue gas, so as to ensure that the impact on the side wall of the reaction tower is small.
