Description

Purified alkari water manufacturing method and apparatus using loess ball containing calcined shell powder

The present invention relates to a method for producing purified alkaline water using an ocher ball containing a plastic shell powder and a device therefor. The water supply means such as a faucet or a shower after the outlet side of a meter connected to a water supply pipe to enter a water supply from a water supply source indoors. The present invention relates to a water purification device which is installed between and sterilizes tap water supplied into a home or facility management body and supplies it to alkaline water.

In recent years, water shortages are accelerating due to climate change due to global warming, and Korea's per capita precipitation is a water shortage country recognized by international organizations, which is only one-tenth of the world average. Water demand continues to increase due to increased living standards and living standards. Despite the government's steady increase in water supply facilities for the past 30 years, the water shortage is likely to intensify in the future.

However, chlorine-based solvents and carcinogenic compounds can be mixed with tap water due to pollution of low-grade rivers and water sources, chlorine treatment in water purification plants, and the problem of aging water pipes is also at home. What is impossible is today's situation.

As a result of a recent survey of students' drinking water at home as a result of their water supply, the result is a duplicate, but 57% of people drink water purifier water, 50% drink boiled tap water, 23% drink bottled water, and tap water. If you drink it as it is 0.2%.

Water hygiene is a very important problem in school health. Elementary school students have a low resistance to disease, so if they are exposed to hazards, they are more likely to develop diseases, especially when drinking water contaminated with pathogenic microorganisms. In the water quality analysis survey installed in elementary, middle and high schools in some areas from April to June of last year, 258 (4.9%) of 5,252 water purifiers in 544 schools were detected more than the standard bacteria such as E. coli and water. Problems have been raised, but this is a limited investigation in some areas, and nationwide, there are many more places where practically no water purifiers are actually installed, and in fact, in the summer, drinking polluted water often causes mass food poisoning accidents. Is reported.

In addition, in recent years, the interest in alkaline water is increasing as a way to prepare for adult diseases, the blood of the human body is a weak alkaline state in the pH range of 7.3-7.4 people eat a lot of acidic foods such as meat, alcohol, soft drinks, People with high mental stress or activity tend to be inclined toward acidity, and when acidification progresses, they are easily fatigued, psychologically unstable or unable to control their emotions, and have an aggressive personality, insomnia. Headache, dizziness, etc. are also reported and skin is worsening.

In addition, when the blood is acidified, the risk of diseases such as high blood pressure or arteriosclerosis increases, cholesterol levels are high, and blood becomes cloudy or stiff, so drinking alkaline water is known to help the health by preventing acidification of the blood. Many studies have been conducted, and various kinds of water purifiers have been developed to increase the functionality of the water to cure diseases or promote health.

Korea's economic development has been rapid, and the rate of water supply has increased from 17.1% in 1961 to 102l per capita in 2001, to 87.8% in 2001 and to 374l per capita in 2005. In the year, the rate of water supply rose to 95%.

Even if the rate of supply of water is increased, the problem of detecting harmful substances in tap water is raised, which requires clean water not only for drinking water but also for general living water, and using high quality water with functionalities such as ionized water, reduced water (alkaline water) and soft water. The desire to do is increasing.

Currently, the water supply pipe is composed of cast iron pipes, and iron is dissolved and escaped by water flowing into the inner wall of the cast iron pipe. In the process, the iron components are oxidized to form iron oxide, in which case the cast iron pipe of the piping system. The silver is corroded severely and when the iron oxides are entangled with each other, they partially block the inside of the cast iron pipe to reduce the water pressure, and the iron components are entangled with each other to form red rust.

Most households avoid drinking tap water due to the problem that microorganisms inhabit and multiply inside the pipes and cause unpleasant odor and serious damage to human health due to slime or scale. Instead of tap water, drinking ground water or commercially available bottled water or using a water purifier.

Looking at the water purification technology disclosed to improve water quality in the meantime, Korean Patent Laid-Open Publication No. 2004-0013037 includes a galvanic cell with one or more sets of titanium, silver-plated copper, and zinc plates, and one or more natural metal catalysts. After that, a technical idea of providing alkaline reduction water using a hydrogen reduction catalyst cartridge filled with natural minerals for far-infrared radiation has been disclosed, and Korean Patent Publication No. 2004-0030760 discloses a current according to the temperature of water through a temperature compensation circuit unit. Attempts to improve the alkaline reduced water content by generating a redox potential (ORP) by controlling the average current and frequency by changing the pulse width according to the PWM method as well as maintaining a constant pH concentration by controlling the pH. It has been disclosed.
