描述了一种通过使用吸湿性盐颗粒调节原始气体来控制表面过滤器灰尘分离操作行为的创新方法。有针对性地操纵表面过滤器的操作行为的基础是，良好的性能会在长循环时间内自我调整。这些是通过过滤阶段期间压降的缓慢增加和再生后的低残余压降来获得的。从技术上讲，这种状态可以通过所谓的原始气体调节来实现。吸湿性盐颗粒的潮解和风化特性可以被认为是尘饼中灰尘颗粒之间形成固体桥的可能性。有了这个概念，理论上可以灵活且有针对性地增强灰尘饼中的内聚力，而无需改变饼层与过滤介质之间的粘附力。
An innovative approach to manipulating the operating behavior of surface filters for dust separation by raw gas conditioning using hygroscopic salt particles is described. The basis for a targeted manipulation of the operating behavior of surface filters is the fact that a favorable performance adjusts itself at long cycle times. These are obtained by a slow increase in pressure drop during the filtration phase and by a low residual pressure drop after the regeneration. Technically, such states can be realized by so‐called raw gas conditioning. The deliquescence and efflorescence properties of hygroscopic salt particles can be considered as possibilities for the formation of solid bridges between dust particles in the dust cake. With this concept, a flexible and targeted strengthening of the cohesion in the dust cake without an accompanying modification of the adhesion between the cake layer and the filter medium is theoretically possible.
