Abstract

An apparatus for washing the iron-poisoned ion exchange resin is composed of ion exchanger, acid tank, chemical dissolving bath, and circulating pipeline with cut-off valve and acid-resistant pump. Its washing process includes preparing chemical solution with proper concentration, washing and rewashing.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a method for cleaning an ion exchange resin device poisoned by iron during the process of preparing softened water. Background technique [0002] The device that undergoes ion exchange reaction in the water treatment process is called an ion exchanger, and the exchanger used to produce softened water is also called an ion exchange softener. Generally, an exchanger in which the ion exchanger operates under static conditions is used, and the softening of raw water and the regeneration of the ion exchange resin are carried out in the same device, and its interior is a fixed structure. [0003] Fill the softener with 0.01×7 strong acidic styrene-based cation exchange resin, the exchange basis: ion exchange resin is a kind of polymer electrolyte, they can ionize in aqueous solution, and the ionization of cation exchange resin in aqueous solution is : <chemistry num="001"> <chem ...
