A large-capacity purification column for water purifiers

Abstract

The invention discloses a high-capacity purification column of a water purifier. The purification column comprises an upper end cover (1), a lower end cover (2), a purification column body A and a purification column body B, wherein the purification column body A is arranged between annular grooves a(3) and c(5), and the purification column body B is arranged between annular grooves b(4) and d(6); both the purification column bodies A and B are separately composed of a first purification column (7), a connecting ring (8) and a second purification column (9) which are connected in sequence; a water inlet connector (11) communicated with the first purification column (7) of the purification column body A is arranged on the upper end cover (1); a water outlet connector (12) communicated with the first purification column (7) of the purification column body B is arranged on the upper end cover (1); a water through hole (15) for communicating two cavities (14) is formed in the lower end cover (2). The high-capacity purification column has the beneficial effects that the structure is compact, the installation is convenient and fast, no resin scrap leakage occurs, the filter effect is good and the treatment amount is large.

Description

technical field [0001] The invention relates to the technical field of water filtration, in particular to a large-capacity purification column for water purifiers. Background technique [0002] Ultrapure water: It not only removes the conductive medium in the water almost completely, but also removes the non-dissociated colloidal substances, gases and organic substances in the water to a very low level. Ultrapure water is the water produced by the American scientific and technological circles in order to develop ultrapure materials (semiconductor original materials, nano fine ceramic materials, etc.) by applying distillation, deionization, reverse osmosis technology or other appropriate supercritical fine technology. Water molecules (H 2 0), there are almost no impurities, and there are no bacteria, viruses, chlorinated dioxins and other organic substances. . [0003] The requirements for water in the laboratory are relatively high, and the laboratory often needs to use p...

AI Technical Summary

Problems solved by technology

[0003] The requirements for water in the laboratory are relatively high, and the laboratory often needs to use pure water to ensure the reliability of the experiment. However, most of the purification columns in the ultrapure water devices used in the laboratory to produce pure water are general-purpose series for civilian products. The filtration effect of the civil product series is far less than the high requirements of the laboratory, resulting in unstable water quality and affecting the normal use of ultrapure water devices

At the same time, the filter material of civilian products is less, which is not conducive to water purification

During the use of the existing purification column, the exchange resin in the vertically placed purification column has a tendency to settle downward due to gravity, and is restricted by the sealing band and cannot expand in the diameter direction, so the purification column is easy to bend and deform. The exchange resin creates a gap between the inner walls of the housing

When the pure water flows downward from the purification column, due to the influence of the gap, a bias flow phenomenon will occur, resulting in incomplete contact between the water flow and the resin, affecting the water quality

Secondly, in the water purification process, as the purification column is used for a long time, resin debris may leak out and affect water quality

At the same time, the existing products need temporary assembly during installation, which makes installation and maintenance difficult, the quality of the pure water produced cannot be guaranteed, and the volume is also large, occupying a lot of installation space
