D641X pneumatic desulfurization butterfly valve product introduction:

In air pollution, sulfur dioxide is an important pollutant, and more than 60% of sulfur dioxide pollutants come from industrial flue gas emissions. With the gradual improvement and improvement of China's environmental standards and the improvement of people's awareness of the environment, China must carry out desulfurization treatment for projects with industrial flue gas emissions in the future. One of the important components in the flue gas desulfurization device is the valve. The requirement for the desulfurization valve is that it can not only resist chloride, oxide, acid, but also harsh abrasive wear and slurry wear and corrosion. The key of FGD butterfly valve is to correctly select the valve material and structural form and prolong the service life of the valve.

A complete desulfurization system is needed in many industrial or power fields At present, the limestone gypsum wet method is used internationally, with one furnace and one tower desulfurization device, and the desulfurization efficiency of this desulfurization device can reach 95.5%. After the limestone slurry system passes through the desulfurization pipeline, the medium will be highly corrosive, which has high requirements for the whole pipeline system, fluid control valves and valve actuators. The special butterfly valve for desulfurization is designed and manufactured according to the special requirements of desulfurization system.
