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 device and a cleaning method for cleaning iron-poisoned ion exchange resin in the process of preparing softened water. Background technique [0002] The device in which the ion exchange reaction occurs in the water treatment process is called an ion exchanger, and the exchanger used to prepare softened water is also called an ion exchange softener. Generally, the ion exchanger is operated under static conditions, and the raw water softening and the regeneration of the ion exchange resin are carried out in the same device, and the inside is a fixed structure. [0003] The softener is filled with 0.01×7 strong acid styrene cation exchange resin. The exchange mechanism: ion exchange resin is a kind of polymer electrolyte, which can be ionized in aqueous solution. The ionization of cation exchange resin in aqueous solution is : <chemistry num="001"> <chem file="03144474_cml001.xml" ...
