摘要
换热表面上形成的污垢,使传热效率降低,流动阻力增大,严重妨碍了换热设备的正常运转,造成能源浪费和经济损失。 本研究主要通过磁控溅射技术,在加热器表面磁控溅射DLC(Diamond-Like Carbon)以抑制污垢沉积,在池沸腾装置中考察处理表面对污垢行为的影响,并将所获结果与未处理的加热器表面进行比较。
In this paper the effect of surface sputtering with diamond - like carbon (DLC) on CaSO4 scale formation was investigated. Fouling runs were carried out under pool boiling conditions with heat fluxes of 100 - 300 kW·m-2 and a saturated CaSO4 concentration at 100℃. The results showed that surface sputtering with DLC reduces CaSO4 scale formation significantly.
