Embodiment Construction

[0029] The invention provides a method for constructing a desulfurization exhaust chimney based on 3D printing and borosilicate glass. Using silicon carbide fiber reinforced borosilicate glass as a building material, 3D printing technology is used as a molding method to prepare a desulfurization exhaust chimney; the specific implementation is described as follows:

[0030] (1) First, calculate the size of the chimney according to the smoke exhaust function requirements of the chimney and the mechanical properties of silicon carbide reinforced borosilicate glass, based on the chimney construction site and the calculated dimensions of the chimney internal diameter and chimney thickness, in the computer Generate a digital 3D model of the chimney. The 3D model takes the center point of the vertical projection of the chimney on the ground as the origin, and uses the Cartesian three-dimensional coordinate axis to establish a series of discrete three-dimensional data. The three-dimens...

Abstract

The invention discloses a method for building a desulfurization exhaust chimney based on three-dimensional (3D) printing and borosilicate glass, belonging to the technical fields of civil engineering and environment protection. The method comprises the following steps: calculating the size of the chimney and generating a digitalized 3D model of the chimney by a computer according to the requirements of an exhaust function of the chimney and the mechanical property of silicon carbide-enhanced borosilicate glass, and then preparing the desulfurization exhaust chimney from silicon carbide fiber-enhanced borosilicate glass as a building material by employing the 3D printing technology as molding means. The silicon carbide fiber-enhanced borosilicate glass used by the method has the characteristics of being good in high-temperature resistance, small in coefficient of thermal expansion, good in resistance to temperature deformation, and strong in resistance to sulfate erosion; meanwhile, the chimney built by using 3D printing is a whole body, so that no joint or gap is generated; no risk of leakage appears; the method has the characteristics of being high in construction efficiency and automatic; the defects caused by labor construction, construction environments and personal operation level are avoided.

Description

technical field [0001] The invention belongs to the technical fields of civil engineering and environmental protection, and in particular relates to a method for constructing a desulfurization and exhaust smoke chimney based on 3D printing and borosilicate glass. Background technique [0002] my country is the largest producer of coal resources in the world. In 2011, my country's coal production accounted for 50% of the world's total production. my country is also a big consumer of coal resources, accounting for 94% of the country's total coal production. Coal is a common fuel for thermal power plants. As of the end of 2011, my country's installed power generation capacity was 1.05 billion kilowatts, of which hydropower was 230 million kilowatts, thermal power was 760 million kilowatts, nuclear power was 11.91 million kilowatts, and wind power was 47 million kilowatts. 72.4% of the total. Coal is a fossil fuel whose main combustible components are carbon (C), hydrogen (H), ...
