Problems solved by technology
The surface of the final product is very rough, and it must be treated by grinding to keep the outer surface smooth and round. Therefore, the traditional process is time-consuming and labor-intensive, the product is not wear-resistant, and the working environment is harsh, which is not conducive to improving labor production efficiency.

Embodiment Construction
[0021] The present invention adopts a new material - glass fiber reinforced plastic (hereinafter referred to as FRP), and adopts a unique method to manufacture the flue gas desulfurization spray pipe, in order to solve the problem of high price, heavy quality and high resistance of stainless steel or alloy steel materials. The disadvantage of unsatisfactory corrosion. Simultaneously, this process also improves the traditional FRP pipeline production process, and proposes the paste production process of the 5-layer structure flue gas desulfurization spray FRP pipeline. The following is the specific content of the present invention:
[0022] 1. Mold preparation
[0023] According to the user's requirements for the product, the mold is processed and manufactured, and the surface of the mold is polished, waxed, etc., the resin material (vinyl unsaturated resin) is prepared, the site is cleaned, and a layer of 50μm PVC film is wrapped on the surface of the mold.
[0024] 2. Paste ...

Abstract
The invention discloses a spraying pipe and manufacturing method in the smoke desulfurizing course, which is overlapped by at least one layer of resin and at least one layer of interval glass fiber surface cushion on the resin surface, wherein the external surface of internal surface layer is secondary internal surface layer, which is overlapped by at least one layer of resin and at least one layer of weaving cushion on the resin surface, the external surface of secondary internal surface layer is structure layer with at least one layer of resin and glass fiber cloth on the resin surface, the secondary surface layer is formed on the external layer of structure layer, which is formed by overlapping at least one layer of resin and at least one layer of coarse interval cushion, the external surface layer is set on the external surface of secondary external surface layer, which is formed by overlapping at least one layer of resin and at least one layer of interval polyethylene grid cloth.
Description
technical field [0001] The invention belongs to a method for treating flue gas discharged after combustion of a large boiler and a device used therefor. 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 is we...
