Problems solved by technology

[0012] Therefore, one of the main problems restricting the development of flue gas desulfurization technology is how to overcome the corrosion prevention and manufacturing difficulties of large spray desulfurization towers.
[0013] Although there are some measures in the prior art, such as adopting high-grade alloy steel, and adopting steel-lined rubber or resin glass flake paint, etc., either because the price is extremely expensive, it is difficult to be widely used, or because of the difficulty in construction and manufacture, it becomes unsuitable. reliable
At present, most desulfurization devices adopt the method of steel-lined resin glass flake coating. However, due to frequent start-up and shutdown, and construction and other reasons, the coating layer is easy to fall off, resulting in the core equipment of the desulfurization device cannot be used normally and for a long time. , must be improved

Abstract

The present invention relates to a special composite material and the application. This composite material comprises inorganic fiber, organic resin, and resin curing accelerator, among which inorganic fiber is 5 to 80 parts by weight (pbw), organic resin 20 to 95 pbw. The ratio of resin curing accelerator to organic resin is 0.01 to 0.1. The composite material can be used to prepare tower of flue gas desulfurizer, which comprises a tower body, a top flue gas pipeline installed on the tower body, a top cover connecting the bottom of the top flue gas pipeline with the tower, a liquid absorption distributor under the top cover, a central section of flu gas pipeline under the liquid absorption distributor, and a bottom plate. The tower body, the top cover and the bottom plate are made of the composite material. By adopting the polymer composite material with comparatively low price to make the flue gas desulfurizer tower, the invention has the advantages of quick and convenient manufacturing, reliable product quality, high performance price ratio and suitability for large-scale popularization.

Description

technical field [0001] The present invention relates to a special composite material and its application, especially its application in the preparation of equipment for removing sulfur oxides in flue gas discharged from boilers, and also relates to the manufacturing method of the equipment. Background technique [0002] Boilers or thermal power plants that use coal or oil as fuel emit a large amount of flue gas. These flue gases contain harmful substances such as SOx, NOx, HCl and HF, among which SOx is the main substance that forms acid rain. Depending on the type of coal burned, SO 2 The content is usually 300-5000ppmv (1000-15000mg / Nm 3 )between. However, the amount of flue gas is huge. In terms of coal-fired boilers, the steam scale ranges from 35T / h to 2500T / h, the capacity of the generating set ranges from 6MW to 1000MW, and the flue gas amount varies from 50,000 Nm 3 / h to 2.5 million Nm 3 , SO 2 Emissions from 1,000 tons / year to 100,000 tons / year. Thanks to SO...
