Description

Technical Field

[0001] The utility model belongs to the technical field of desulfurization tower device, and specifically relates to a high-efficiency multi-stage cross-flow desulfurization tower device. Background Art

[0002] The desulfurization tower is the core equipment in the flue gas desulfurization system. It converts sulfur dioxide in the flue gas into harmless sulfate or other compounds through chemical reactions, thereby reducing air pollution. After the flue gas enters the desulfurization tower, it comes into contact with the desulfurizer sprayed in the tower, so that the sulfur dioxide in the flue gas is absorbed into the desulfurizer. Multi-stage cross-flow desulfurization towers are often used in desulfurization. In order to avoid the desulfurizer being entrained in the flue gas after desulfurization, a demisting mechanism is usually set on the upper part of the tower body to filter the desulfurizer entrained in the flue gas, so that the discharged gas is clean and has no residue.

[0003] In the use of existing high-efficiency multi-stage cross-flow desulfurization tower devices, the shape of the baffle of the defogger mechanism is usually fixed, and the baffle angle of the baffle cannot be adjusted. When the flue gas rises faster, if the baffle angle is smaller, the flue gas is less obstructed by the baffle during movement, which easily leads to the flue gas passing through the defogger mechanism for too short a time. When the flue gas rises slower, if the baffle angle is larger, the flue gas is more obstructed by the baffle during movement, and the flue gas passes through the defogger mechanism for too long, which easily leads to the flue gas passing through the defogger mechanism for too short a time, making it difficult to adapt to flue gases with different rising speeds, and the desulfurization efficiency is insufficient. Utility Model Content

[0004] The purpose of the utility model is to provide a high-efficiency multi-stage cross-flow desulfurization tower device, which can drive the lifting frame to move up and down through the lifting mechanism, so that the baffle assembly can be activated to adjust the baffle angle of the baffle assembly, so as to adapt to flue gas with different rising speeds and improve the desulfurization efficiency.

It should be understood that the following text is only used to describe one or several specific implementation methods of the utility model, and does not strictly limit the scope of protection of the specific request of the utility model.

[0027] like Figure 1-5 As shown, a high-efficiency multi-stage cross-flow desulfurization tower device includes a tower body 10, and also includes:

[0028] A bottom plate 20, the bottom plate 20 is fixedly connected to the inside of the tower body 10;

[0029] A lifting mechanism 30, wherein the lifting mechanism 30 is installed on the bottom plate 20;

[0030] A lifting frame 40, the lifting frame 40 is slidably connected to the top of the bottom plate 20, and the lifting frame 40 is fixedly connected to the lifting mechanism 30;

[0031] A baffle assembly 50, wherein a plurality of baffle assemblies 50 are provided and are all installed between the bottom plate 20 and the lifting frame 40, and the baffle assembly 50 includes a plurality of rotating plates 51 that are rotatably connected to each other;

[0032] When the lifting mechanism 30 is actuated, it drives the lifting frame 40 to slide up and down, so that adjacent rotating plates 51 rotate relative to each other to adjust the deflection angle of the deflector assembly 50 .

[0033] It should be noted that the outside of the lifting frame 40 is slidably connected to a plurality of guide rods 21 , and the guide rods 21 are fixedly connected to the bottom plate 20 .

[0034] In this embodiment, when the deflection angle of the baffle assembly 50 needs to be adjusted, the lifting mechanism 30 is actuated to drive the lifting frame 40 to slide up and down along the bottom plate 20, and the lifting frame 40 drives the top of the baffle assembly 50 to slide up and down, so that adjacent rotating plates 51 rotate relative to each other, and the angle between adjacent rotating plates 51 is adjusted, thereby adjusting the deflection angle of the baffle assembly 50, so as to adapt to flue gas with different rising speeds and improve the desulfurization efficiency. Among them, the lifting frame 40 cooperates with the guide rod 21, so that the process of the lifting frame 40 sliding up and down along the bottom plate 20 is more stable.

[0035] like Figure 4 As shown, the bottom of the baffle assembly 50 is rotatably connected to the base plate 20 , and the top of the baffle assembly 50 is slidably connected to the lifting frame 40 .

[0036] It should be noted that the top of the baffle assembly 50 is also rotatably connected to the lifting frame 40 .

[0037] In this embodiment, when the lifting frame 40 moves up and down, the lifting frame 40 drives the top of the baffle assembly 50 to move up and down. At the same time, the top of the baffle assembly 50 also rotates along the lifting frame 40, thereby facilitating the adjustment of the baffle angle of the baffle assembly 50.

[0038] like Figure 3 , Figure 4 and Figure 5 As shown, both sides of the lifting frame 40 are provided with slide grooves 41 , and both ends of the top of the baffle assembly 50 are fixedly connected with protrusions 52 , and the protrusions 52 are slidably matched with the slide grooves 41 .

[0039] It should be noted that the protrusion 52 is also rotatably matched with the slide groove 41 .

[0040] In this embodiment, when the lifting frame 40 drives the baffle assembly 50 to move up and down through the slide groove 41, the protrusion 52 slides along the slide groove 41 and the protrusion 52 also rotates inside the slide groove 41, which facilitates relative rotation between adjacent rotating plates 51, thereby facilitating adjustment of the baffle angle of the baffle assembly 50.

[0041] like Figure 3 and Figure 4 As shown, the lifting mechanism 30 includes a motor 31 fixedly connected to the base plate 20 , a lead screw 32 is fixedly connected to the output end of the motor 31 , a slider 33 is connected to the external thread of the lead screw 32 , and the slider 33 is fixedly connected to the lifting frame 40 .

[0042] It should be noted that a second shell 37 is provided outside the motor 31, and the second shell 37 is fixedly connected to the bottom plate 20 to prevent flue gas and desulfurizer from entering the inside of the second shell 37, thereby reducing the damage of flue gas and desulfurizer to the motor 31 during the desulfurization process.

[0043] In this embodiment, the motor 31 drives the lead screw 32 to rotate after being activated, the lead screw 32 drives the slider 33 to move up and down in the vertical direction, and the slider 33 drives the lifting frame 40 to move up and down, thereby facilitating the adjustment of the deflection angle of the deflector assembly 50.

[0044] like Figure 4As shown, a first shell 34 is provided outside the slider 33 , and the first shell 34 is fixedly connected to the bottom plate 20 . A first folded cloth 35 is provided between the top of the slider 33 and the first shell 34 , and a second folded cloth 36 is provided between the bottom of the slider 33 and the bottom plate 20 .

[0045] It should be noted that a plurality of horizontal folds are provided inside the first folded cloth 35 and the second folded cloth 36 , and the horizontal folds are distributed along the vertical direction to facilitate the increase or decrease of the height dimension of the first folded cloth 35 and the second folded cloth 36 in the vertical direction.

[0046] In this embodiment, when the slider 33 moves upward, the height dimension of the first folded cloth 35 decreases and the height dimension of the second folded cloth 36 increases. When the slider 33 moves downward, the height dimension of the first folded cloth 35 increases and the height dimension of the second folded cloth 36 decreases. This makes it easier to prevent the flue gas and desulfurizer from entering the interior of the first shell 34 from the side of the first shell 34 close to the lifting frame 40 during the up and down movement of the slider 33, thereby reducing the damage of the flue gas and desulfurizer to the screw 32 during the desulfurization process.

[0047] like Figure 2 and Figure 3 As shown, a foldable enclosure 60 is provided between the lifting frame 40 and the bottom plate 20 , the top of the foldable enclosure 60 is fixedly connected to the lifting frame 40 , and the bottom of the foldable enclosure 60 is fixedly connected to the bottom plate 20 .

[0048] It should be noted that a plurality of transverse folds are provided inside the folding enclosure 60 along the vertical direction, so as to facilitate the increase or decrease of the height dimension of the folding enclosure 60 along the vertical direction.

[0049] In this embodiment, during the up and down movement of the lifting frame 40, the lifting frame 40 drives the top of the folding enclosure 60 to move up and down, so that the height of the folding enclosure 60 increases or decreases, thereby preventing smoke from being discharged from between the lifting frame 40 and the bottom plate 20, and facilitating the smoke to move upward through the channel between adjacent baffle assemblies 50.

[0050] The working principle of the utility model is as follows: after the motor 31 is activated, it drives the lead screw 32 to rotate, the lead screw 32 drives the slider 33 to move up and down in the vertical direction, the slider 33 drives the lifting frame 40 to move up and down, and the lifting frame 40 drives the top of the baffle assembly 50 to slide up and down, so that the protrusion 52 slides along the slide groove 41 while the protrusion 52 also rotates inside the slide groove 41, so that the adjacent rotating plates 51 rotate relative to each other to adjust the angle between the adjacent rotating plates 51, thereby adjusting the baffle angle of the baffle assembly 50, so as to adapt to the flue gas with different rising speeds and improve the desulfurization efficiency.

[0051] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be regarded as the protection scope of this utility model. The structures, devices and operating methods not specifically described and explained in this utility model shall be implemented according to the conventional means in this field unless otherwise specified and limited.
