Description

Technical Field

[0001] The utility model relates to a porous distributor protection structure of a desulfurization absorption tower. Background Art

[0002] The porous distributor of the desulfurization absorption tower in a power plant is a commonly used fluid distribution equipment. It evenly distributes the gas entering the absorption tower to multiple outlets to ensure that each outlet can obtain the same flow rate. The distributor has a simple structure, high reliability, no complex fluid control mechanism, and is not prone to failure. It is an important equipment in the environmental protection facilities of the power plant. The distributor is generally installed on the support beam 15-18 meters above the absorption tower. The support beam is made of square steel. Because the distributor is blown by the fluid during operation, it vibrates and rubs against the support beam, causing wear of the support beam. The acidic slurry in the spray of the absorption tower corrodes the support beam. Accelerates the damage of the support beam. The support beam is in a confined space and cannot be observed during operation. Once corrosion occurs, it may cause the support beam to break, which will have a great impact on the environmental protection indicators of the power plant and even require shutdown for treatment. Utility Model Content

[0003] The utility model aims to solve the above-mentioned problems and provides a porous distributor protection structure for a desulfurization absorption tower.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A protective structure for a porous distributor of a desulfurization absorption tower comprises: a porous plate and a support beam, a pad is provided between the porous plate and the support beam, a buckle sleeve is hung on the pad, the pad comprises a plurality of hanging plates, adjacent hanging plates are interlocked, the hanging plates are polytetrafluoroethylene flat plates, both ends of the hanging plates have arc-shaped hanging ears, one end of the hanging plate has an embedding groove, and the other end has a convex edge.

[0006] The porous distributor protection structure of the desulfurization absorption tower, the buckle sleeve is an Ω plate structure.

[0007] The porous distributor protection structure of the desulfurization absorption tower, the buckle sleeve is a polytetrafluoroethylene plate.

[0008] The porous distributor protection structure of the desulfurization absorption tower has a circle of grooves in the embedded groove and a circle of convex strips on the convex edge. Beneficial Effects

[0009] 1. The utility model adds a layer of polytetrafluoroethylene plate between the porous distributor and the support beam of the desulfurization absorption tower, which can effectively prevent the friction between the distributor and the support beam and protect the support beam. Compared with rubber, asbestos board and other materials, polytetrafluoroethylene has excellent chemical stability, corrosion resistance, sealing, high lubricity and non-stickiness, electrical insulation and good aging resistance. These characteristics are very suitable for the working environment of the desulfurization absorption tower and are the best choice for protective pads.

[0010] 2. The utility model is provided with a buckle sleeve, which is hung on the pad to form a protective sleeve for protecting the support beam, thereby preventing the acidic slurry in the absorption tower spray from corroding the support beam.

[0011] 3. The utility model provides a groove in the embedding groove and a convex strip on the convex edge. When adjacent scrapers are embedded, the convex strip is embedded in the groove, which can achieve a certain sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS
