Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a desulfurization tower for lime production. Background Art

[0002] A desulfurization tower is a device used to treat sulfur dioxide in industrial waste gas. Its working principle is mainly based on chemical reactions. The absorbent reacts with sulfur dioxide in the flue gas to convert it into sulfate or other forms, thereby reducing the sulfur dioxide content in the flue gas. The principles of desulfurization towers can be divided into two types: wet desulfurization and dry desulfurization. Dry desulfurization: the absorbent and flue gas enter the desulfurization tower separately, and the sulfur dioxide in the flue gas is removed by physical adsorption and chemical reaction. This method does not require water as a medium, so it is suitable for some special fields. Dry desulfurization requires the use of a desulfurization tower for chemical reaction before completing the desulfurization treatment.

[0003] The existing dry desulfurization device inputs the flue gas to be desulfurized into the inner side of the desulfurization tower, and then places chemicals inside the desulfurization tower to allow the chemicals to fully react with the flue gas to achieve the purpose of desulfurization. However, the position where the chemicals are placed is limited by the inner diameter of the desulfurization tower. When laying the chemicals, the reaction is not sufficient due to the limitation of the inner diameter of the desulfurization tower, thereby affecting the desulfurization efficiency.

[0004] Therefore, a desulfurization tower for lime production is proposed. Utility Model Content

The placement structure 3 also includes an arc tube 34 arranged at the top of the disc 31 and a bottom plate 35 fixed at the bottom end of the inner side of the arc tube 34. The two sides of the arc tube 34 are rotatably connected with a rotating rod 39. The end surface of the rotating rod 39 is fixed with an extension plate 37. The bottom end of the extension plate 37 is evenly provided with hollow holes 36. The extension plate 37 extends to the side of the arc tube 34. The end surface of the arc tube 34 is against the inner wall of the tower body 1. The bottom end of the arc tube 34 is fixed with a docking rod 33. The docking rod 33 The bottom end is abutted against the inner side of the docking tube 32, and the docking rod 33 and the docking tube 32 form a splicing structure. During use of this embodiment, after the placement structure 3 is assembled to the tower body 1, the extension plates 37 on both sides of the arc-shaped tube 34 at the top of the placement structure 3 can be unfolded through the rotating rod 39. After the expansion, the side wall of the extension plate 37 is abutted against the inner wall of the tower body 1. In this way, the extension plate 37 can be used to extend the placement area of ​​the arc-shaped tube 34, and chemicals can be placed on the top of the bottom plate 35 and the extension plate 37 to increase the placement area. Increasing the placement area can increase the contact area between chemicals and sulfide flue gas, thereby improving the efficiency of the chemical reaction.
