Desulfurization tower spray pipe

The winding layer structure of the desulfurization tower spray pipe is divided into three parts from the outside and inside

1.Damaged layer:The arrangement method is to evenly arrange this part inside the absorption tower,which belongs to the outer structure of the winding layer and is composed of glass fiber surface felt,resin,and silicon carbide.Its main function is to prevent damage.This layer of glass fiber surface felt:resin:silicon carbide:1:57:38(mass ratio),with a thickness of approximately 5mm.

2.Layer:This part is composed of a rich resin layer and an intermediate layer,consisting of glass fiber surface felt,flue gas desulfurization spray pipe,and desulfurization tower spray pipe resin,forming energy and located below the damaged layer.The resin rich layer has a resin content greater than 90%and a thickness of approximately 5mm;The middle layer has a resin content of 70%to 80%and a thickness of approximately 3-4mm.

3.Enhancement layer:This part is directly wrapped around the outer wall of the pipeline and is mainly designed to withstand pressure and other loads.The absorption tower spray is an important component of the core equipment of the flue gas desulfurization system(FGD)-the absorption tower.The selection of the spray layer pipeline should fully consider the corrosion and erosion effects of fly ash and spray slurry in the flue gas at the inlet of the FGD device on the spray layer,as well as the possible impact loads during operation.The pipeline system should have good strength and stiffness.The thickness is determined according to equation(1)based on the load conditions.This layer has a resin content of 30-40%and is composed of glass fiber,chopped fiber felt,and resin.Mainly responsible for the design requirements of stiffness and strength.
