Wet calcium FGD technology can be the most effective way to remove sulfur dioxide from flue gas, but also to remove the dust, which is the effective method to control the concentration of sulfur dioxide and particulate matter in the atmospheric environment. Wet calcium flue gas purification technology basic principle: the lime or limestone slurry or solution, and the gas contact, flue gas sulfur dioxide absorption into the liquid phase, and generate a calcium sulfite reaction in liquid phase and lime or limestone.

In the process of gas liquid contact, the solid dust particles are captured at the same time. But a lot of users on the desulfurization equipment in the corrosion, fouling, wear, blockage and other aspects of the problem, so the more wear-resistant ceramic ball came into being. KOWOV a series of ceramic valves are widely used in power plant flue gas desulfurization system, in addition to slag system and combustion system; soda salt water system, distillation system; paper mill pulp control system. Especially in the power plant desulfurization (FGD) project, the ceramic valve is a good solution to the FGD conditions of high chloride ion corrosion, high solid content wear two major issues. In the process of adjusting the limestone slurry and gypsum slurry wastewater, KOWOV ceramic valve is the ideal valve and is the best substitute for imported products, which has a very high value of popularization. Performance features:

★、All parts of the contact with the media are structural ceramic materials, their chemical stability and high hardness (HRC90), second only to diamond. Therefore, this valve has a very high wear resistance, corrosion resistance, erosion resistance, and good heat insulation, thermal expansion of small.

★、Using ball grinding equipment and advanced manufacturing technology, high precision ball roundness, surface quality, and the ceramic valve seat to research using Zr02 ceramics self lubrication can be achieved very good sealing performance, really achieve good ceramic on ceramic seal.

★、Completely changed the metal hard seal ball valve leakage, torque, sealing surface is not resistant to corrosion, wear and tear.

★、Ceramics good abrasion resistance, so that the valve durability, high reliability. Using long life, is a titanium alloy Monel valves and valve 2-4 times.

★、Granular medium for high hardness, or a soft particles but also corrosive medium, the valve has an unparalleled absolute advantage, is currently the only suitable for such a medium of the valve.

★、Can directly receive 4-20mA or 1-5V signal, easy to achieve proportional control valve (position control), good control module to ensure the long-term stability of the use of.
