Electric desulfurization butterfly valve

Selection and application of electric/pneumatic desulfurization butterfly valves (limestone slurry and gypsum slurry):
1. Introduction to desulfurization and desulfurization butterfly valve:
The desulfurization device of thermal power plants is a mandatory environmental protection measure of the country. At present, there are two mature desulfurization technologies abroad: limestone/gypsum flue gas desulfurization and ammonia flue gas desulfurization. The most commonly used desulfurization equipment in China is limestone/gypsum flue gas desulfurization (hereinafter referred to as wet flue gas desulfurization). The principle of wet flue gas desulfurization is to make limestone slurry, which is atomized into droplets of a certain diameter by a nozzle. The droplets come into contact with the flue gas, absorbing and removing sulfur dioxide (SO2), sulfur trioxide (SO3), fluoride (HF), and chloride (HCL) in the flue gas, and generating calcium sulfite. Then, an oxidation air system oxidizes the calcium sulfite to calcium sulfate.
The main media in wet flue gas desulfurization process are limestone slurry and gypsum slurry, which not only have high chloride ion content and high solid content, but also have fast flow rate. Therefore, it has a significant impact on the erosion of valve components.
The butterfly valve for electric/pneumatic desulfurization is mainly designed and manufactured according to the different working conditions of various process systems in the wet flue gas desulfurization device.
There are two types of butterfly valves for electric/pneumatic desulfurization: clamp type and flange type, and clamp type with flange can also be used. The sealing seat material is made of wear-resistant rubber and special molding process to accommodate the entire part in contact with the medium. The butterfly plate material is selected from different special alloys according to the chloride ion content of each process system.
The main characteristics of electric/pneumatic desulfurization butterfly valves are good sealing performance, flexible and lightweight opening and closing, high flow capacity, wear resistance, and erosion resistance. It is currently an ideal valve for wet flue gas desulfurization equipment in thermal power plants.
Our company has developed a series of desulfurization butterfly valves based on high-performance centerline butterfly valves to meet market demand. Our company's desulfurization butterfly valve has been widely used in flue gas desulfurization equipment.
