Description

A hydrogen-rich composite filter element

technical field

The utility model relates to the technical field of water purification, in particular to a hydrogen-rich composite filter element.

Background technique

In 1975, "Science" reported that after 14 days of continuous breathing of high-pressure hydrogen (97.5%) in an animal model of skin cancer, the tumor volume shrunk significantly, suggesting that high-pressure hydrogen is effective in treating skin cancer. It is believed that the anti-tumor mechanism of high-pressure hydrogen may be related to the effect of hydrogen It is related to anti-oxidation. In 2001, French scholar Gharib et al. reported that breathing 8 atmospheres of high-pressure hydrogen can treat the inflammatory response caused by hepatic schistosomiasis infection, and proposed that the direct reaction of hydrogen and hydroxyl radicals is the basis for the treatment of inflammatory damage. In the article In particular, the anti-inflammatory effect of hydrogen deserves further study. Due to the great danger of high-pressure hydrogen, it cannot be effectively used in clinical practice, and the research of hydrogen molecular biology has not attracted the attention of the biomedical community. It should be pointed out that since 2007, Professor Ota Chengnan of Japan Medical University published a paper "Hydrogenactsasatherapeuticantioxidantbyselectivelyreducingcytotoxicoxygenradicals" in the world-renowned magazine "Natural Medicine" ("The effect of hydrogen acts on the antioxidant treatment of oxygen free radicals by selectively reducing cytotoxicity 》), found that hydrogen molecules can remove free radicals in the human body, and have a good therapeutic effect on aging and various chronic diseases caused by free radicals. This discovery officially opened the prelude to the research on the biological effects of hydrogen molecules and related industries.

After rapid development in recent years, so far, researchers have used a variety of experimental animal models and clinical case observations to determine that hydrogen can treat many diseases. The most important effect of hydrogen is that it can treat oxidative stress-related diseases well. Effects, such as neonatal cerebral hypoxia, Parkinson's disease, etc.; recently, there are also research reports on the use of hydrogen to treat major human diseases such as diabetes, atherosclerosis, hypertension, and tumors. However, due to the flammability and explosiveness of hydrogen, there are certain limitations in the use of hydrogen intake from the respiratory tract. At present, the ideal way is to dissolve hydrogen in water to make a hydrogen-rich aqueous solution (commonly known as "hydrogen-rich water"), so that consumers can drink hydrogen-rich water to ingest hydrogen, which greatly improves its use. convenience and safety. In fact, after the promotion and experience of hydrogen-rich water in the market in recent years, a group of consumers have enjoyed the effects of hydrogen-rich water, and a large number of consumers in sub-health (such as constipation, insomnia, forgetfulness, etc.) are drinking After using hydrogen-rich water, the health of the body has been greatly improved, and the market for hydrogen-rich water has begun to flourish.

However, there are not many technical methods for the preparation and use of hydrogen-rich water, which greatly restricts the development of the hydrogen-rich water industry, including:

Method 1: Pre-preparing hydrogen-rich water and storing it in a special container for packaging, transportation and sales (Chinese patent 200780043207.4, Chinese patent 201110247829.8, Chinese patent 201410047486.4). In this technical method, problems such as the easy release of hydrogen and the need for high airtightness of the packaging are always unavoidable technical problems, which bring a lot of inconvenience to manufacturers, sellers and consumers.

Method 2, electrolysis method, prepares hydrogen-rich water by electrolysis of tap water, mineral water, etc. (note: not pure water), and allows consumers to make and drink it now (Chinese patent CN201120340424.4). The disadvantages of this method include: (1) At present, my country's water bodies are seriously polluted. Direct electrolysis of tap water to produce hydrogen-rich water may electrolytically decompose pollutants in tap water, thereby introducing pollutants, which is not conducive to the health of consumers; (2) If the water body is rich in minerals, the electrolysis electrodes are easily passivated, which greatly reduces the life of the electrolysis machine; (3) The hydrogen-rich water prepared by this method is usually highly alkaline and has a strong astringent taste, which is not subject to consumption. reader's favorite.

Method 3. Purification hydrogen production method. In view of the current situation of serious water pollution in my country, my country's water purifier industry has developed rapidly. In 2014, the industry market size was about 20 billion yuan. The compound growth rate in the past three years has exceeded 60%. It is predicted that the market capacity of the water purification industry will exceed 100 billion yuan. We clearly see that consumers' awareness and desire to purchase water purification products have greatly increased. As a nascent health industry, hydrogen-rich water has very high requirements for water quality itself and subsequent marketing. Combining hydrogen-rich water with traditional water purification products is a major innovation in the combination of technology and market. Chinese patent CN201020543005.6 discloses a hydrogen-rich activated water generator, which can be connected to a reverse osmosis water purifier to convert reverse osmosis purified water into hydrogen-rich water, which is an attempt to purify hydrogen production.

It should be pointed out that although my country's reverse osmosis water purifier is the mainstream product in the water purification industry, it has been criticized for a long time:

(1) Not environmentally friendly, every 1 part of pure water will waste 3 parts of waste water;

(2) The failure rate of the machine is high, because it uses a large number of electronic valve heads, if the assembly technology and process are not perfect, it will cause a large number of failures;

(3) After-sales service is cumbersome, because it has multiple filter elements and various accessories, which brings great challenges to after-sales service;

(4) There are many accessories and joints, which are easy to leak and have high safety risks;

(5) Pure water does not contain minerals, which is not easy for consumers to be healthy.
