Abstract

The invention discloses a chimney constructed by novel corrosion-resistant materials and a construction method thereof and a sleeve chimney with the chimney. The chimney comprises multiple fiber reinforced resin profiles, the fiber reinforced resin profiles are mutually connected in the longitudinal direction to form a column, and the multiple columns are mutually connected in the transverse direction to form to be in a hollow cylinder shape; a cavity of which the upper end and the lower end are open is limited in each fiber reinforced resin profile, filler is arranged in each cavity, and any two fiber reinforced resin profiles which are adjacently arranged in the transverse direction are staggered in the longitudinal direction. According to the embodiment of the chimney, the design thought similar to a fiber reinforced resin sandwich plate is adopted, the fiber reinforced resin profiles and the filler are used in a matched mode, the structural function integration of the chimney is achieved, the corrosion protection problem of the chimney is thoroughly solved, the structural strength of the chimney is high, the manufacture cost is lowered, and the construction is easy.

Description

technical field [0001] The invention belongs to the technical field of civil engineering and environmental protection and energy saving, and in particular relates to a chimney constructed of novel corrosion-resistant materials, a construction method thereof and a sleeve chimney provided with the chimney. Background technique [0002] In recent years, my country has strictly controlled the emission of air pollutants and promulgated a series of mandatory laws and regulations. One of the most important measures is to require all thermal power plants to desulfurize boiler flue gas. At present, the most common desulfurization process for thermal power plants is the limestone wet desulfurization process with high efficiency and stable operation. Since the desulfurization flue gas is highly corrosive after being treated by this process, it is necessary to carry out anti-corrosion modification of the equipment. Among them, the most important thing is to install an anti-corrosion l...
