Description

Technical Field

[0001] This utility model relates to the field of mechanical seal replacement technology, and in particular to a mechanical seal replacement device for an absorber side agitator. Background Technology

[0002] The side agitator in the absorber tower is a key piece of equipment in wet desulfurization systems (such as limestone / gypsum flue gas desulfurization processes). Through a side-mounted agitator, it achieves efficient mixing and uniform distribution of the slurry. The side agitator uses a propeller-type impeller to generate axial thrust and normal force, creating an up-and-down turbulent liquid flow. This prevents solid particles such as limestone and gypsum from settling at the bottom of the slurry pool, ensuring slurry fluidity. The rotating impeller drives the slurry to form a spiral high-speed flow, drawing liquid from the low-speed zone into the high-speed zone, expanding the gas-liquid contact area, promoting the chemical reaction between sulfur dioxide in the flue gas and the absorbent (such as limestone slurry), and improving desulfurization efficiency. Uniform mixing of the slurry accelerates the oxidation of calcium sulfite to calcium sulfate, promotes gypsum crystal growth, and simultaneously increases the limestone dissolution rate, optimizing the desulfurization reaction kinetics. Compared to top-mounted agitators, the side agitator is directly installed on the side wall of the absorber tower, avoiding overhead space occupation and more effectively covering the entire slurry pool, reducing local concentration gradients.

[0003] Due to its complex structure, the mechanical seal of the agitator on the absorber side of the absorption tower requires, under normal circumstances, the absorption tower to be shut down and the slurry drained for replacement when it is damaged. This is difficult and economical. Therefore, this invention proposes a mechanical seal replacement device for the agitator on the absorber side of the absorption tower to address the shortcomings of the existing technology. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a mechanical seal replacement device for the agitator on the absorption tower side. The screw can pull the agitator shaft of the agitator on the absorption tower side to move outward. Simultaneously, the mechanical seal moves outward and, by driving the first and second clamps of the anti-overflow sealing mechanism to move closer together, seals the connection between the agitator shaft and the absorption tower, preventing overflow.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The first hoop clamp and the second hoop clamp are symmetrically arranged, and both the first hoop clamp and the second hoop clamp are connected to the synchronous movement driving mechanism.

[0007] Further improvement lies in that: the tool support is in a "C" shape. Threaded holes are provided on the tool support. The screw rod is threadedly connected to the threaded holes.

A bidirectional screw rod is rotatably provided on one side between the first mounting plate and the second mounting plate. A guide rod is provided on the other side between the first mounting plate and the second mounting plate. Both the first hoop clamp and the second hoop clamp are threadedly connected to the bidirectional screw rod, and both the first hoop clamp and the second hoop clamp are slidably connected to the guide rod.

[0012] Further improvement lies in that: the upper end of the bidirectional screw rod penetrates through the top of the first mounting plate and a knob is provided.

[0020] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0021] according to Figure 1-4 As shown, this embodiment proposes a mechanical seal replacement device for the absorber side agitator, including a tool bracket 1, a lead screw 2, a connecting bracket 3, and an anti-overflow sealing mechanism. The tool bracket 1 is detachably installed with the base 4 of the absorber side agitator. The tool bracket 1 is provided with the lead screw 2, and a connecting sleeve 5 is rotatably provided at one end of the lead screw 2. The connecting sleeve 5 is connected to one end of the agitator shaft 18 of the absorber side agitator. A connecting bracket 3 is provided on one side wall of the tool bracket 1. A first mounting plate 6 and a second mounting plate 7 are respectively provided above and below the inner side of one end of the connecting bracket 3.

The anti-overflow sealing mechanism includes a first clamp 8 and a second clamp 9. The first clamp 8 and the second clamp 9 are symmetrically arranged, and both the first clamp 8 and the second clamp 9 are connected to the synchronous movement drive mechanism.

[0022] When using the mechanical seal replacement device for the absorber side agitator of this utility model, the tool bracket 1 is installed on the base 4 of the absorber side agitator, and then one end of the agitator shaft 18 of the absorber side agitator is connected to the connecting sleeve 5. By rotating the screw 2, the agitator shaft 18 is pulled out, and the mechanical seal on the agitator shaft 18 is separated from the outer wall of the absorber. After the mechanical seal moves, the synchronous movement drive mechanism is quickly operated to drive the first clamp 8 and the second clamp 9 to move closer to each other and hold the agitator shaft 18. The first clamp 8 and the second clamp 9 seal the through hole at the installation location of the agitator shaft 18 to prevent overflow.

[0023] The tool support 1 is U-shaped and has a threaded hole 10. The lead screw 2 is threaded into the threaded hole 10. The tool support 1 has symmetrical adjustment holes 11, each containing a fastening bolt 12. The tool support 1 is detachably mounted to the base 4 via the fastening bolts 12.

This invention allows for quick and convenient disassembly and replacement of the mechanical seal, improving operational efficiency.
