Pneumatic desulfurization denitration butterfly pneumatic valve _ power plant desulfurization special pneumatic valve butterfly pictures

Pneumatic desulfurization butterfly valve ( Pneumatic line with rubber butterfly valve) Is designed for power plant desulfurization and denitration engineering design of a kind of anticorrosive wear-resisting butterfly pneumatic valve, give full consideration to the desulfurization serous corrosion and wear of pneumatic valve, pneumatic valve plate lining is the only guarantee access to serous parts, other parts don't be limestone ( Or lime paste) Slurry erosion. Therefore, pneumatic valve and pneumatic valve stem don't need to use expensive alloy ( 2205). Materials, thus greatly save the cost. Pneumatic desulfurization butterfly valve pneumatic seat design unique completely separates pneumatic valve body and fluid, compared with other similar pneumatic valve, it has a better way of pneumatic valve seat firmly, in-place replacement pneumatic seat quickly, pneumatic valve in zero leakage, and less friction. Pneumatic valve pneumatic butterfly valve plate with high-performance alloy ( 2205). Material, effectively resist slurry corrosion and wear.






pneumatic desulfurization denitration butterfly valve can be widely used in water and electricity, water, building, air conditioning, petroleum, chemical, food, medicine, textile, paper making, water supply and drainage and other fluid on the pipeline as the adjusting and intercepting use, and can be taken by the material changes, to apply to different media such as water, gas, oil, temperature - shall apply 20～80℃。 By changing the pneumatic valve plate seal, o-rings, disc, shaft, such as material, can be used a variety of medium and different temperature.


principle of pneumatic desulfurization butterfly valve:


refers to the sulfur in coal desulfurization with methods such as calcium base becomes solid to prevent burning generating SO2, the desulfurization method can generally be divided into before combustion desulfurization, desulfurization and burned in the combustion desulfurization 3 classes. Desulfurization butterfly pneumatic valve must satisfy the corrosion, wear and tear, velocity, temperature and so on several requirements, all the fossil fuels containing sulfur, especially coal, combustion generated after a large amount of SO2, serious air pollution. To control the pollution, the most effective way is to flue gas desulfurization. Currently the most widely used in the world, including China & other; Lime ( The limestone) — Gypsum & throughout; Wet desulphurization technology. The process in the system, involving a variety of corrosive medium, and the particle material, have strong corrosion and wear and tear on equipment. So the material and structure of the pneumatic valve form have special requirements.
