Description

Technical Field

[0001] This application relates to the technical field of safety control devices for desulfurization absorption towers, and particularly to a desulfurization absorption tower. Background Technology

[0002] The aluminum electrolysis process generates flue gas containing pollutants, requiring a wet desulfurization system for purification. During operation, if the desulfurization system experiences abnormal control or if excessive impurities in the flue gas enter the absorption tower, the heavy metal content in the absorption tower slurry will increase. This increased heavy metal ion concentration leads to increased surface tension, making the slurry surface prone to foaming. Once foaming and overflow of the absorption tower slurry occur, appropriate measures must be taken promptly to prevent serious consequences.

[0003] The current method for handling abnormal bubbles is to install a liquid level sensor at the overflow port of the tower. However, because the foam is fragile and easily breaks, it has low sensitivity to the sensor and cannot accurately control the sensor. Utility Model Content

[0004] This application provides a desulfurization absorption tower that solves the problem of inaccurate sensor control.

[0005] This application provides a desulfurization absorption tower, comprising: a desulfurization absorption tower body, the inner top of which has a bubble overflow cavity; a lifting mechanism disposed within the bubble overflow cavity, the lifting mechanism including a float vertically movable within the bubble overflow cavity and a touch sensor fixed to the top of the bubble overflow cavity; a controller, the input end of which is connected to the touch sensor for signal transmission; and a first alarm, the first alarm being connected to the output end of the controller for signal transmission. When the foam within the desulfurization absorption tower pushes the float upward and triggers the touch sensor, the controller controls the first alarm to issue a warning.

[0006] In one possible implementation, a transmission rod is fixed to the upper surface of the float, the number of transmission rods being the same as the number of touch sensors, and each touch sensor and each transmission rod being located on the same vertical line.

[0007] In one possible implementation, a spacer shell is fixed to the inner top of the desulfurization absorption tower, and the bubble overflow cavity is formed between the side wall of the spacer shell and the inner wall of the desulfurization absorption tower.

[0008] In one possible implementation, the spacer housing is an L-shaped structure, with its upper end fixedly connected to the inner top of the desulfurization absorption tower, and its three sides fixedly connected to the three inner sidewalls of the desulfurization absorption tower.

[0009] In one possible implementation, protrusions for supporting the float plate are fixed on both sides of the inner wall of the bubble overflow cavity. When the float plate contacts the protrusions, the lower surface of the float plate and the lower surface of the spacer shell are on the same horizontal plane.

[0010] In one possible implementation, a liquid level sensor is installed at the bottom of the spacer housing, the liquid level sensor is connected to the input terminal of the controller for signal transmission, and the output terminal of the controller is connected to a second alarm.

[0011] In one possible implementation, liquid accumulation shells are installed on both sides of the desulfurization absorption tower. The liquid accumulation shells are connected to the bubble overflow cavity through a bubble removal groove. A puncturing component is provided in the bubble removal groove for puncturing the bubbles.

[0012] In one possible implementation, the puncture assembly includes a support strip plate fixedly connected to the inner wall of the defoaming tank, and a plurality of puncture nails are fixed to the side of the support strip plate near the float plate.

[0013] In one possible implementation, the defoaming tank is located above the interior of the liquid accumulation shell to prevent the backflow of foamed liquid after breakage.

[0014] In one possible implementation, the bottom surface of the liquid accumulation shell is provided with a drain port, the lower end of the drain port is fixedly connected to a drain pipe, and a solenoid valve is provided inside the drain pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This application involves setting a horizontal plate section and a vertical plate section inside the desulfurization absorption tower body. A bubble overflow cavity is formed on one side of the vertical plate section, and a lifting mechanism is set in the bubble overflow cavity. When bubbles are generated inside the desulfurization absorption tower body, a large number of bubbles will concentrate and lift the floating plate upward, causing the transmission rod to contact the touch sensor, and finally causing the first alarm to sound, accurately and effectively reminding the staff that there are bubbles overflowing.

[0017] 2. Degassing tanks are opened on both sides of the desulfurization absorption tower, and puncturing components are installed in the degassing tanks. When bubbles enter the liquid collection shell, the support plates will puncture the bubbles, so that liquid enters the liquid collection shell, making it easy to collect bubbles and convenient to discharge them.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0027] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0028] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Please see Figures 1 to 5 This application provides a desulfurization absorption tower, including a desulfurization absorption tower body 1. A spacer shell is provided at the top inner part of the desulfurization absorption tower body 1. The spacer shell is generally L-shaped and includes a horizontal plate part 3 and a vertical plate part 5. The upper end of the vertical plate part 5 of the spacer shell is fixedly connected to the top inner part of the desulfurization absorption tower body 1. The two sides of the vertical plate part 5 and the horizontal plate part 3 of the spacer shell are respectively fixed to the two inner side walls of the spacer shell. The side of the horizontal plate part 3 away from the vertical plate part 5 is fixed to the corresponding inner side wall of the spacer shell.

[0031] A bubble overflow cavity 7 is constructed between the side wall of the vertical plate portion 5 of the spacer shell and the inner wall of the desulfurization absorption tower body 1. The bubble overflow cavity 7 is elongated.

[0032] A lifting mechanism 6 is provided inside the bubble overflow cavity 7. The lifting mechanism 6 includes a float 601 that is vertically movable inside the bubble overflow cavity 7. A pair of transmission rods 602 are fixed on the upper surface of the float 601. A pair of touch sensors 603 are installed on the inner top of the desulfurization absorption tower body 1. The transmission rods 602 and touch sensors 603 on the same side are located on the same vertical line. The touch sensors 603 are connected to the controller 11 for signal transmission. The output of the controller 11 is connected to the first alarm 10 for signal transmission. When a large number of bubbles overflow into the bubble overflow cavity 7, the float 601 will be pushed upward by the bubbles, so that the two transmission rods 602 will contact the two touch sensors 603 respectively to trigger the touch sensors 603.

[0033] When excessive gaseous impurities enter the desulfurization absorption tower 1, causing bubbles to form in the liquid, a spacer shell is installed inside the desulfurization absorption tower 1. One side of the vertical plate 5 of the spacer shell is a bubble overflow cavity 7, and a float 601 is vertically moved and installed inside the bubble overflow cavity 7. The float 601 is adapted to the cross-sectional size of the bubble overflow cavity 7. At this time, the concentrated bubbles will lift the float 601. The upward movement of the float 601 will drive the two transmission rods 602 to move upward and contact the two touch sensors 603 respectively. After being touched, the touch sensors 603 will send an electrical signal to the controller 11. The controller 11 controls the first alarm 10 to sound an alarm. It is worth noting that the first alarm 10 is installed in the main control room so that the staff can detect the problem in time.

[0034] Furthermore, protrusions for supporting the float plate 601 are fixedly connected to the inner walls of both the front and rear sides of the desulfurization absorption tower body 1. When the float plate 601 is in its lowest state, the lower surface of the float plate 601 is on the same plane as the lower surface of the vertical plate part 5, which prevents the float plate 601 from falling into the desulfurization absorption tower body 1 when there is no liquid in the desulfurization absorption tower body 1, thereby achieving the function of limiting the float plate 601.

[0035] Furthermore, a liquid level sensor 4 is installed on the lower surface of the horizontal plate 3 to monitor the liquid level inside the desulfurization absorption tower 1. The liquid level sensor 4 is connected to a controller 11 for signal transmission. The controller 11 is installed outside the desulfurization absorption tower, and its specific location is not limited. The output of the controller 11 is connected to the second alarm 12 for signal transmission. When the liquid inside the desulfurization absorption tower 1 reaches the highest liquid level, the liquid level sensor 4 will send an electrical signal to the controller 11, thereby controlling the second alarm 12 to sound an alarm through the controller 11. The second alarm 12 can be installed on the side wall of the desulfurization absorption tower 1 or in the main control room, and is not limited here.

[0036] Furthermore, liquid collection shells 2 are fixed on both sides of the desulfurization absorption tower 1, and degassing grooves are opened on both sides of the desulfurization absorption tower 1. The degassing grooves are located inside the two liquid collection shells 2, and puncturing components 13 are installed in the degassing grooves to puncture the bubbles.

[0037] Furthermore, the puncture assembly 13 includes a support plate 132 fixed inside the bubble removal tank. The support plate 132 is horizontally fixed to the inner wall of the bubble removal tank. Several puncture nails 131 are fixedly connected to the side of the support plate 132 near the float plate 601, which are used to quickly puncture the bubbles before they enter the liquid accumulation shell 2, so as to facilitate the collection of bubble liquid.

[0038] The bottom of the liquid collection shell 2 is provided with a drain port 9, and the lower end of the drain port 9 is fixedly connected to a drain pipe 8. A solenoid valve is installed in the drain pipe 8. The solenoid valve is connected to the controller 11 for signal transmission, and the controller 11 controls the opening of the solenoid valve. The bubble degassing tank is located inside the upper part of the liquid collection shell 2, so that the broken bubble liquid can remain in the liquid collection shell 2 and prevent the broken foam liquid from flowing back.

[0039] When the float plate 601 rises, a large number of bubbles will enter the cavity 7. Under the obstruction of the lifting mechanism 6 and the squeezing action of the bubbles, the bubbles will enter the two liquid collection shells 2 through the two bubble discharge channels. Since there are puncturing components 13 in the two bubble discharge channels, when the bubbles enter, the puncturing nails 131 will puncture the bubbles, so that liquid enters the liquid collection shell 2. The liquid collected in the liquid collection shell 2 can be discharged by opening the solenoid valve on the drain pipe 8, which avoids the bubbles from flowing out directly and causing environmental pollution, and also avoids the phenomenon that the bubbles are inconvenient to discharge in the liquid collection shell 2.

In the description of this application, it should be understood that if terms such as "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0041] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
