An ultra-purification column of a laboratory water purifier

Abstract

The invention discloses a super purification column for a laboratory water purifier. The super purification column comprises an upper end cover (1), a lower end cover (2), a purification column body A (3) and a purification column body B (4), wherein the top end and bottom end of the purification column body B (4) are respectively welded in an annular groove b (6) and an annular groove d (8); micro-porous filters I (9) positioned in an annular groove a (5) and the annular groove b (6) are formed in the bottom surface of the upper end cover (1); a water inlet joint (10) communicated with the purification column body A (3) and a water outlet joint (11) communicated with the purification column body B (4) are formed in the upper end cover (1); and a water through hole (21) communicated with two cavities (13) is formed in the lower end cover (2). The super purification column disclosed by the invention has the beneficial effects that the purification column is compact in structure and convenient and rapid to mount, resin scrap leakage is avoided, and the filtering effect is good.

Description

technical field [0001] The invention relates to the technical field of water filtration, in particular to an ultra-purification column of a laboratory water purifier. Background technique [0002] 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 civil 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 d...

Problems solved by technology

[0002] 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
