Problems solved by technology

General parts other than reinforcement parts, elbows / horizontal sections account for a large proportion of the main body of the chimney, so they must meet the requirements of mechanical properties, but the design is very difficult. So far, there are no engineering examples of FRP chimneys in large-scale thermal power plants in my country.

Abstract

The invention relates to a glass fiber reinforced plasticordinary part cylinder wall structure and a chimney with the structure. The glass fiber reinforced plastic ordinary part cylinder wall structure comprises a lining function layer, an intermediate structure layer and an optional outer protection layer. The intermediate structure layer comprises a plurality of structure sub-layers. The structure sub-layers comprise a structure single layer A, a structure single layer B, a structure single layer C and a structure single layer D. The thickness t of the intermediate structure layer is no smaller than 8mm and no larger than 25mm. The glass fiber reinforced plastic ordinary part cylinder wall structure is novel, has good axial mechanical property and circumferential mechanical property and is convenient to construct, quality control is convenient, the service life is long, and the glass fiber reinforced plastic ordinary part cylinder wall structure is suitable for a large thermal power plant.

Description

technical field [0001] The invention relates to a chimney, in particular to a glass-reinforced steel common part tube wall structure and a chimney with the structure. Background technique [0002] Fiber-reinforced plastics are high-performance composite materials formed with fibers and their products as reinforcing materials, synthetic resin as matrix materials, and a specific molding process. Glass Fiber Reinforced Plastics (Glass Fiber Reinforced Plastics, also known as glass fiber reinforced plastics, the internationally recognized abbreviation symbol is GFRP or FRP) is a kind of fiber reinforced plastics, which is a functional type made of synthetic resin and glass fiber through a composite process. Composite materials have excellent designability, processability and repairability. [0003] In the past, domestic FRP was mostly used for storage tanks and pipelines. Its material design focused on meeting product functions and did not require high mechanical properties. Wh...
