Regeneration method and regeneration device of softening core of pressure type softening multi-stage water purifier

Abstract

The invention relates to a regeneration method and a regeneration device of a softening core of a pressure type softening multi-stage water purifier. The regeneration method comprises the following steps: replacing a purifying core installed at the earlier stage of a softening core by a regeneration core, wherein the regeneration core contains solid or liquid regenerant; in the process of regeneration, starting a water source to enable water to enter the softening core from the regeneration core, and discharging the water discharged from the softening core as waste water; and after regeneration, disassembling the regeneration core, and then, assembling the original purifying core. The regeneration device comprises the regeneration core, wherein the regeneration core comprises a regeneration core shell; the solid or liquid regenerant is filled in the regeneration core shell; the solid or liquid regenerant is filled in the regeneration core shell in bulk or filled in the shell of a regenerant component in bulk; and the regenerant component is installed in the regeneration core shell. The regeneration method of the invention has simple operation, and the regeneration of the softening core is relatively thorough and has better effect; and simultaneously, the regeneration device of the invention has low manufacturing cost, and the regeneration core shell can be reused.

Description

technical field [0001] The invention relates to the technical field of regeneration of a softening core in a water purifier, in particular to a softening core regeneration method and a regeneration device of a pressure-type softening multi-stage water purifier. Background technique [0002] It is used to remove suspended solids, different colors, odors, odors, tap water disinfection by-products (trihalomethanes, haloacetic acids, etc.), organic matter, microorganisms (pathogenic bacteria), viruses, heavy metals, etc. It is equipped with purification materials (such as non-woven fabrics, PP cotton, activated carbon, microporous ceramics, hollow fiber ultrafiltration membranes, nanofiltration membranes, reverse osmosis membranes, etc.), and its shell is equipped with circular water inlets and outlets The cylindrical device is called a purification core, commonly known as a filter element. [0003] For the purpose of removing hardness substances such as calcium and magnesium i...

AI Technical Summary

Problems solved by technology

This regeneration method is also more troublesome, and there are also problems such as poor regeneration effect, incomplete regeneration and difficult cleaning of the regeneration solution.

[0008] Therefore, there is a need for a softening core regeneration method and a regeneration device for a pressure-type softening multi-stage water purifier that makes the regeneration of the softening core simple and thorough, and the utilization rate of the regeneration agent is high. For the purpose of softening core regeneration, the regeneration device does not have the function of purifying water quality, nor does it have the function of softening water quality
