软水技术中,逆流再生的优势已经普遍得到业内人士的认同,但相对于顺流再生,逆流相对于复杂的控制条件使得逆流再生的优势难以实现。为了能简单实现全自动软水器的高交换容量,通过一系列的实验对比分析顺流、逆流再生及满床工艺在软水器上的运用。通过实验证明了满床逆流再生工艺在全自动软水器运用的有效性及满床工艺的优势。 In softener technology, the advantages of countercurrent regeneration have generally been recognized by the industry, but countercurrent relative to complex control conditions makes the advantages of countercurrent regeneration difficult to achieve relative to downstream regeneration. In order to realize the high exchange capacity of fully-automatic water softener, a series of experiments were conducted to compare the use of water-softener with downstream flow, countercurrent flow regeneration and full-bed flow. The experiment proved the full bed countercurrent regeneration technology in the fully automatic water softener and the effectiveness of the full bed technology advantages.
