厢式压滤机的两种用法

 厢式压滤机的两种用法      对于粘稠性的悬浊液,厢式压滤机这种设计结构是特别合适的。而且新的结构设计能够在滤板加热的过程中同时施加真空,可将滤饼干燥到含水量低于1%的水平。 。为了证实其机能的优胜性,

以20ram厚度的石灰滤饼进行的运行试验表明,在低于100℃和4kPa的压力前提下操纵时只需约1h就能将含水量降低到1% ,而传统的真空干燥机则需要4h左右。热水在板框间进行轮回,加热金属板框并干燥滤饼。金属板的传热速率比用PP制的板片进步4倍左右。目前这种滤机的能力可以做到1~5kt/a的水平,合用于精细化工和制药行业。因为新的设计结构能够进行双侧过滤,从而减少了过滤时间。  德国威斯巴登的Filtech(过滤技术)公司推出了一种由拜耳技术服务公司和斯特拉斯堡过滤器公司合作开发的加热板式过滤器,这种也可以改装成传统型压滤机的过滤器将过滤和干燥组合在一个单元中,从而大大减少丁过滤工序的时间和投资本钱。这种过滤系统由夹在金属板框之间的膜式过滤板叠加而成。此外,悬浊液或滤出液通道厢式压滤机的清洗也可以组合在过滤工序的下游一侧,对于传统的板式压滤机这也是做不到的
The two uses of van filter press are particularly suitable for the viscous suspension. Moreover, the new structural design can simultaneously apply vacuum during the heating process of the filter plate, so that the cake can be dried to a level below 1% of water content. In order to prove the superiority of its function,
The operation test of lime cake with 20ram thickness showed that water content could be reduced to 1% at less than 100 C and 4kPa under pressure, and the traditional vacuum dryer needed about 4H. Hot water circulates between the frames, heating the metal frame and drying the cake. The heat transfer rate of metal plate is about 4 times higher than that made of PP. At present, the capacity of the filter can reach 1 ~ 5kt / a level, which is suitable for the fine chemical industry and the pharmaceutical industry. Because the new design structure can carry out bilateral filtering, thus reducing the filtering time. Filtech, in Wiesbaden, Germany, has launched a heated plate filter developed by the Bayer technology service company and the Strasbourg filter company, which can also be converted into a traditional filter filter that combines filtering and drying in a single unit, thereby greatly reducing the filtration process. Time and investment cost. The filtration system is made up of a membrane filter plate sandwiched between metal plates and frames. In addition, the cleaning of the wing filter press of the suspension or filter fluid can also be combined on the downstream side of the filter process, which is not possible for the traditional plate filter press.
