Manufacturing process of desulfurization spraying pipeline

Abstract

The invention relates to the technical field of spraying pipelines, and relates to a manufacturing process of a desulfurization spraying pipeline. The manufacturing process comprises the following steps: (1) cladding a polyethylene film: coating an anti-wear coating on the outer side wall of a mould pipe, and cladding the polyethylene film on the outer side wall of the mould pipe after completionof the coating of the anti-wear coating; (2) setting a surface layer; (3) setting a structural layer; (4) setting the outer surface; and (5) demoulding. The manufacturing process of the desulfurization spraying pipeline disclosed by the invention has the advantages that through cooperation between the polyethylene film and the anti-wear coating, the mould pipe is conveniently separated from the spraying pipeline, and in a separation process, the effect of friction loss on the inner side wall of the spraying pipeline is reduced.

Description

technical field [0001] The invention relates to the technical field of spray pipes, in particular to a manufacturing process of desulfurization spray pipes. Background technique [0002] Power station and industrial boilers usually use coal, oil or gas as fuel. Because these fuels generally contain sulfur components, harmful substances such as sulfur dioxide will be produced during combustion. Limestone / lime-gypsum wet flue gas desulfurization devices are widely used in large power plant boilers to remove sulfur dioxide in flue gas after boiler combustion. Limestone / lime-gypsum wet flue gas desulfurization plant needs limestone or lime slurry as absorbent to absorb sulfur dioxide in flue gas. Limestone slurry is prepared by mixing limestone powder with a certain particle size and water. The important step of wet flue gas desulfurization is to use limestone slurry to spray and wash the flue gas containing sulfur dioxide in the absorption tower, so the spray washing device i...

Problems solved by technology

If the adhesion between the surface layer and the mold tube is low, friction loss will occur on the surface layer in contact with the mold tube during the demoulding process, resulting in unevenness; if the adhesion between the surface layer and the mold tube is high, the It will directly cause cracks in the mold pipe, which will affect the quality of the spray pipe
