Description

Technical Field

[0001] This utility model relates to the technical field of flue gas treatment equipment, and in particular to a flue gas desulfurization device for smelting. Background Technology

[0002] In industrial processes such as smelting, a large amount of flue gas containing sulfur dioxide is generated. If it is directly emitted, it will cause environmental problems such as acid rain. Therefore, flue gas desulfurization technology is needed to use specific devices and methods to make the flue gas react chemically with the desulfurizing agent, thereby removing most of the sulfur elements, reducing the sulfur content of the flue gas, and achieving emission standards.

[0003] When desulfurizing flue gas, desulfurization towers are the most commonly used equipment. However, existing desulfurization towers cannot adjust their desulfurization operations in a timely manner when the sulfur content of the flue gas flues, resulting in unstable desulfurization effects and substandard treatment of high-sulfur flue gas, causing serious pollution to the atmospheric environment. Therefore, when the sulfur content of the flue gas surges, the gas-liquid contact within the desulfurization tower is insufficient, resulting in low desulfurization efficiency. Furthermore, it leads to high energy consumption and maintenance costs during equipment operation. Frequent malfunctions and repairs not only affect production progress but also increase the company's operating costs. Utility Model Content

[0004] The purpose of this invention is to provide a flue gas desulfurization device for smelting, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The motor can make the drive ring rotate through the spur gear. The helical tooth groove on the drive ring meshes with multiple helical gears, thereby cooperating with the rotating shaft to realize the synchronous rotation of multiple sector plates.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, an installation cylinder is installed inside the desulfurization tower, and multiple sector plates are rotatably installed inside the installation cylinder via a rotating shaft.

A shaft seat 9 is fixedly installed on one side of each first fixing seat 8. A center seat 10 is fixedly installed in the middle of the installation cylinder 7, and a rotating shaft 11 is rotatably connected between the installation cylinder 7 and the center seat 10. A support ring 12 is fixedly installed on the outside of the desulfurization tower 1, and a drive ring 13 is movably installed on the support ring 12. A frame 14 is also fixedly installed above the support ring 12. A motor 15 is fixedly installed on the frame 14, and the motor 15 is electrically connected to an external main controller via a connecting wire.

[0023] like Figure 2 As shown, an ultraviolet fluorescence detection device is fixedly installed inside the desulfurization tower 1. By setting up the ultraviolet fluorescence detection device, the sulfur content of the flue gas can be calculated by detecting the fluorescence intensity.

[0024] like Figures 2-5 As shown, a sector plate 16 is fixedly installed on the rotating shaft 11 located between the mounting cylinder 7 and the center seat 10. Multiple rotatable and adjustable sector plates 16 are installed inside the mounting cylinder 7 to facilitate control of the exhaust volume of the desulfurization tower 1. Multiple second fixed seats 17 are fixedly installed on the outside of the desulfurization tower 1. A shaft seal 18 is fixedly installed on one side of each second fixed seat 17. One end of the rotating shaft 11 passes sequentially through the desulfurization tower 1, the second fixed seat 17, and the shaft seal 18, and is fixedly installed with a helical gear 19. A rotating groove 21 is opened inside the support ring 12, and multiple balls 22 are rotatably installed inside the groove 21. Multiple connecting rods 20 are also fixedly connected between the support ring 12 and the desulfurization tower 1. The rotating groove 21 and balls 22 inside the support ring 12 can provide a driving mechanism. The rotation of ring 13 is provided by the following conditions: the upper end of the drive ring 13 is provided with a helical tooth groove 23, the inner side of the drive ring 13 is provided with a straight tooth groove 24, and the inner and outer sides of the drive ring 13 located below the straight tooth groove 24 are provided with limiting grooves 25. The lower end of the drive ring 13 is rotatably installed in the rotating groove 21, and the limiting groove 25 is engaged with multiple balls 22. The helical tooth groove 23 is meshed with multiple helical gears 19. The output end of the motor 15 is fixedly installed with a spur gear 26, which is meshed with the straight tooth groove 24. The motor 15 can make the drive ring 13 rotate through the spur gear 26. The helical tooth groove 23 on the drive ring 13 is meshed with multiple helical gears 19, so as to cooperate with the rotating shaft 11 to realize the synchronous rotation of multiple sector plates 16.

[0025] It should be noted that this utility model is a flue gas desulfurization device for smelting. When the sulfur-containing flue gas generated from smelting enters the desulfurization tower 1, the ultraviolet fluorescence detection device installed inside the desulfurization tower 1 starts to work. This device detects the fluorescence intensity, calculates the sulfur content of the flue gas, and transmits the data to an external main controller. The external main controller makes a judgment based on the sulfur content data and controls the motor 15 to operate. The spur gear 26 at the output end of the motor 15 meshes with the spur tooth groove 24 inside the drive ring 13, thereby causing the spur gear 26 to drive the drive ring 13 to rotate on the support ring 12. The rotating groove 21 inside the support ring 12 and the rotatable ball bearings 22 inside the rotating groove 21 provide low-friction rotation conditions for the rotation of the drive ring 13. At the same time, the upper end of the drive ring 13... The helical groove 23 meshes with the helical gear 19. When the drive ring 13 rotates, it drives the helical gear 19 through the helical groove 23, which in turn causes the rotating shaft 11 to rotate. When multiple rotating shafts 11 rotate, multiple sector plates 16 rotate synchronously in the mounting cylinder 7, thereby reducing the gas output of the desulfurization tower 1 and increasing the residence time of the flue gas in the desulfurization tower 1, so that it can fully contact and react with the spray liquid. If the sulfur content of the flue gas is low, the main controller controls the motor 15 to rotate the sector plate 16 to a larger opening angle to increase the gas output, while ensuring that the spray volume of the spraying mechanism 5 matches it.
