Production method of softened water purifier special for boiler

Abstract

The invention discloses a production method of a softened water purifier special for a boiler. The softened water purifier comprises a multi-medium filter device, a compressed activated carbon filter device, a silicon-phosphorus crystal corrosion prevention and scale inhibition device, a cation exchange resin filter device and a UF(ultra-filtration) membrane filter device, wherein a bolt which is in screwed connection with a cylinder is arranged on a valve seat of a closed container, a screw nut which is in screwed connection with the valve seat is arranged in an upper opening of the cylinder, a screw nut and a silicon rubber sealing ring which are in screwed connection with a filter element are also arranged in the center of the valve seat, a bolt and a UF membrane filter element which are in screwed connection with the valve seat are arranged at the upper part of the filter element, a water inlet is formed in the left side surface of the valve seat, and a water outlet is formed in the right side surface of the valve seat; and a water outlet of the cation exchange resin filter device is communicated with a water inlet of the UF membrane filter device. The softened water purifier disclosed by the invention is economical and practical, and can be used for providing qualified and healthy purified water for units which need softened water such as steam boilers, hot-water boilers, hotels, restaurants and apartments.

Description

technical field [0001] The invention relates to water purification equipment, in particular to the manufacturing field of boiler water purifiers used by urban and rural enterprises and institutions. Background technique [0002] With the continuous advancement of industrialization, the problem of environmental pollution is becoming more and more serious, whether in developed areas or poor areas, the increasing pollution of water resources, the safety of drinking water has repeatedly touched people's fragile nerves, and has gradually become a global challenge. Pollution has the most serious impact on industrial boilers and domestic boilers. Units with conditions have installed simple water purification devices in front of the boiler water inlets. Units without conditions directly use tap water or underground surface water. These underground surface waters are seriously polluted. Partial pollution, the pollution is even more heinous, especially calcium (Ca2+), magnesium (Mq2+)...

AI Technical Summary

Problems solved by technology

[0003] There are many water softener products on the market, which are relatively simple in design and structure, low in technical content, and have many defects, especially in the purification of underground surface water, repurification of tap water, and antibacterial and scale inhibition. It is mainly designed based on the re-purification of urban tap water to achieve the purpose of clean water. It cannot solve the problem of urban and rural enterprises and institutions boilers and population directly using underground surface water or tap water. After purification, it is better than the People's Republic of China "Drinking Water Sanitation Standard", become the purpose of boiler water and drinking water
