novel p4/6 type patented configuration feather vane type demister proprietary internals have been installed in the pointed inside or outside sites of mvr vessel per dynamic principles, in order to remove the droplets from the evaporation steam produced by mvr with high performance separation efficiency and high block-proofing characteristics, which can protect the heat-pumps, steam compressors or other steam machines in the down stream from damages by much big size droplets or crystal particles, and can avoid the collection of droplets or crystal particles in the down stream pipes and the relevant corrosion damages, as well as the excess emissions of salts and nitrogen element in ammonia entrained in off gas and condensates.
诺卫 p4/6型专利组态结构形式的羽叶除沫器专有内件，按照流体动力学要求布置在蒸发结晶浓缩器内部或外部指定位置，高效分离脱除多效蒸发浓缩结晶器产生的二次蒸汽中携带的液滴液沫，并对分离过程析出的结晶盐粒具有高效抗堵塞性能。其可保护下游热泵、蒸气压缩机及其它用汽设备免遭液滴液沫和结晶盐粒损坏，并可避免这些液滴液沫和结晶盐粒在下游管线设备积聚造成腐蚀损失，以及避免排放气和凝液盐类和氨氮超标。
