Process characteristics of deionized water equipment
This equipment is produced by Wenzhou Haidoneng Environmental Protection Equipment Technology Co., Ltd. It is a one-ton automatic reverse osmosis pure water equipment with softening belt.
1, deionized water equipment, is an ion exchange system.Ion exchange system is a traditional water treatment process through anion and cation exchange resin to replace all kinds of anion and cation in water. Anion and cation exchange resin can be collocated in different proportions to form ion exchange positive bed system, ion exchange negative bed system and ion exchange mixed bed system.And the mixed bed system is usually used in reverse osmosis and other water treatment processes used to produce ultra-pure water, high pure water terminal process, it is used to prepare ultra-pure water, high pure water is one of the means of irreplaceable.Process characteristics of the equipment are as follows:
(1) Ion exchange equipment is a traditional deionized water equipment, whose water quality is stable and the cost is relatively low.In the past, the power plant boiler supply water is treated by positive bed + negative bed + mixed bed.
(2) With the development of reverse osmosis, EDI and other processes, ion exchange equipment has more disadvantages such as complex operation, difficult automation, waste of acid and alkali, high operating cost, and more and more applications in deep treatment of reverse osmosis.
(3) small ion exchange equipment often use plexiglass exchange column, conducive to the observation of the operation of the resin.Such as mixed ion exchanger regeneration stratification is sufficient, whether the cation is "toxic", etc., resin loss, etc.
(4) The large-scale ion exchange equipment adopts carbon steel lined with epoxy resin or rubber lining, and the visual device is reserved in the middle to facilitate the online observation of the regenerated liquid water level during ion regeneration.
