Description

Titanium plasma hydrogenation machine

The present invention relates to a water treatment device which is made of pure titanium pipe and can be used in a tap water purifier; and in particular to a water treatment device which has the functions of filtering, hydrogen production, chlorine removal and small molecule conversion.

Water treatment technology has long been based on membrane filtration. The materials of the housing and filter element of household water purifiers are quite diverse, and they are basically plastic and activated carbon fibers. They must be discarded and replaced regularly, and cannot be cleaned and reused. Over the years, they consume high costs and a large amount of materials. However, if they are not replaced on time, they will cause secondary pollution and the risk of bacterial infection. In addition, there are industrial washable filter systems that use metal stainless steel housings and fiber filter elements; there are also filter housings and filter elements made of titanium metal, which are used in the chemical industry to resist acid and alkali corrosion, and are rarely seen in commercially available filters for drinking water.

The water filtration devices currently available on the market use at least three or four, and at most seven or eight filter tubes. For example, a typical reverse osmosis (RO) water purifier uses seven to eight filter tubes plus a vacuum tank. However, the more filter tubes there are, the better. On the contrary, the risk may be higher and the relative cost may be higher.

Therefore, there is a need for a water treatment device that reduces the number of filter tubes, allows filter elements to be cleaned and reused, and integrates multiple functions such as filtration, sterilization, chlorine removal, heavy metal removal, scale removal, hydrogen production, and small molecule reduction.

Pure titanium is a safe and non-toxic metal with good bioavailability, light weight and acid and alkali corrosion resistance, making it suitable as a water container. An oxide film will naturally form on the surface of titanium metal, or it can be treated by high-temperature heating and oxidation. It is a material with excellent corrosion resistance and high coating stability. High-temperature sintered titanium powder is also used in water treatment filter elements, which are suitable for solid-liquid separation of low-viscosity liquid containing rigid particles.

Titanium dioxide has been found to have the photochemical property of decomposing water molecules into hydrogen under ultraviolet light, so it can be used as a photocatalyst material. Titanium dioxide has better photocatalytic activity when its crystal structure is in the tantalum phase. Since the energy gap of tantalum phase titanium dioxide is about 3.2 electron volts, the wavelength of the required light energy can be converted to 387.5 nm by using the energy gap size. Therefore, in order to excite the electrons of titanium dioxide from the valence band to the conduction band, an ultraviolet light source with a wavelength less than 387.5 nm must be provided so that titanium dioxide can produce redox reactions and achieve the effects of removing odors or decomposing impurities. Common titanium dioxide photocatalyst materials are coated on filters for air filtration.

Ultraviolet light (UV-C) with a wavelength range of 100 to 280 nm has been proven to have a sterilizing function. Professional water purification systems and general drinking water have widely used UV sterilization to achieve the purpose of microbial control.

In the application of improving water molecules, the surface plasmon resonance (SPR) effect has been used to make water contact with nano-metal particles and illuminate them to obtain small molecular water. Nano-gold particles absorb LED green light with a wavelength of 532 nm to produce a surface plasmon resonance effect, which will cause water to resonate and break some hydrogen bonds in the water, weakening the water molecule structure and forming small molecule water. The activated small molecule water has significant conductivity, high permeability, and anti-inflammatory and anti-free radical benefits.

In addition, nanosilver can also be used for antibacterial purposes based on electrostatic effects. Since bacterial cell membranes are mostly negatively charged, silver ions carry positive charges. Silver ions can penetrate cell membranes due to electrostatic charges and react chemically with thiol groups on bacterial proteins to coagulate, achieving a sterilizing effect. Nanosilver filters are also used in water purification systems.

However, there is still no design that integrates titanium metal materials, semiconductor materials, photochemistry (such as photocatalytic reaction and surface plasmon resonance) and other water treatment technologies.

The purpose of the present invention is to provide a water treatment device that integrates pure titanium materials and application technology, which has multiple functions of water treatment such as filtration, sterilization, chlorine removal, heavy metal removal, scale removal, hydrogen production, and small molecule conversion, so as to produce drinking-grade hydrogen-containing small molecule water.

The present invention provides a water treatment device, which comprises: A tubular shell made of pure titanium material, the interior of which has a containing space extending along a transverse axis; An ultraviolet lamp tube with a wavelength of 380 nm, which is covered with a quartz tube, and is inserted into the tubular shell from a side tube at the center of the tubular shell in a direction perpendicular to the transverse axis; A titanium tube cover is disposed at each end of the tubular shell, each of which is connected to the two ends of the tubular shell, and the tube cover at one end is connected to a water inlet, and the tube cover at the other end is connected to a water outlet; The first filter element is made of sintered pure titanium powder material, and has a filter element opening connected to the tube cover at the water inlet end, so as to be arranged in the accommodation space of the tubular shell, wherein the shell of the first filter element has a silver particle coating inside, and a cold cathode ultraviolet sterilizer with a wavelength of 265 nm is arranged therein; and The second filter element is made of sintered pure titanium powder material, and has a filter element opening connected to the tube cover at the water outlet end, so as to be arranged in the accommodation space of the tubular shell, wherein the shell of the second filter element has a nano-gold particle coating inside, and a cold cathode green light surface plasmon resonance reactor with a wavelength of 532 nm is arranged therein.

The titanium tube shell, tube cover and filter element of sintered pure titanium powder of the present invention have all been polished and subjected to high-temperature oxidation treatment, so it is not easy for bacteria to grow in the container and produce odor; and it can be cleaned and used repeatedly, without the need to replace the filter element like a general water filter, which produces a large amount of consumables. The main structure of the water treatment equipment of the present invention is designed with pure titanium materials. The pure titanium materials used must undergo the following processing procedures, including: polishing treatment, thermal oxidation treatment, CNC cutting and laser welding. The high temperature thermal oxidation treatment temperature is 400℃ to 900℃. Different colors of appearance will be produced according to the temperature. 400℃ can form golden yellow, 500℃ can form blue, 600℃ can form purple, 700℃ to 800℃ can form gray-red, and 900℃ can form a gray titanium oxide film.

The titanium tube covers disposed at both ends of the tubular housing are each composed of a first flange and a second flange, which are fixed by a plurality of titanium bolts. The first flange is connected to the filter element opening through its central through hole, and the filter element is disposed in the accommodation space of the tubular housing; one side of the second flange is connected to the first flange, and the other side is connected to a water pipe adapter through its central through hole.

The pore size of the sintered pure titanium powder filter element in the first filter element is 2 µm. Tap water is introduced into the interior of the shell of the first filter element through the water inlet, and overflows from the inside to the outside of the first filter element shell to the containing space of the tubular shell for primary filtration. The pore size of the sintered pure titanium powder filter element in the second filter element is 0.2 µm. The water that has been initially filtered in the containing space of the tubular shell enters the second filter element shell from the outside of the second filter element shell, and after ultrafiltration, it is discharged through the water outlet.

While being filtered by the first and second filter elements, the silver-plated particles on the inner layer of the shell of the first filter element and the irradiation of ultraviolet light with a wavelength of 265 nm have a sterilization effect and act as a photocatalyst reactor to produce chlorine removal and hydrogen production; the nano-gold particles on the inner layer of the shell of the second filter element group and the irradiation of green light with a wavelength of 532 nm can act as a surface plasmon resonance reactor to reduce water molecules.

Therefore, the water treatment equipment of the present invention that integrates pure titanium materials and application technologies is equivalent to a device combination with the following functions: (1)     Ultraviolet light sterilizer: The pure titanium filter element combined with the cold cathode ultraviolet lamp with a specific wavelength of 265 nm is placed in the first filter element to sterilize the tap water introduced from the water inlet with ultraviolet light; (2)     Photocatalyst reactor: The pure titanium shell combined with the ultraviolet lamp with a specific wavelength of 380 nm is placed in the purified water after filtration by the first filter element to perform a photocatalytic reaction between water, photocatalyst, and titanium dioxide to remove chlorine, decompose pollutants, and produce hydrogen; (3)    Plasma resonance reactor: The pure titanium filter element and the cold cathode green light 532 nm wavelength lamp are combined and placed in the second filter element. The green light illumination and the gold particles coated on the filter element are used to perform surface plasma resonance on the purified water filtered by the first filter element, resulting in small molecule water and hydrogen production, thus improving the water quality.

The present invention also provides a water purification process for tap water passing through the water treatment equipment of the present invention, which includes: Step 1: Dual effects of filtration and sterilization Tap water is introduced into the first filter element with a pore size of 2 µm from the water inlet, and internal pressure is generated inside the first filter element. The water passes through the filter element from the inside to the outside, and the particle impurities in the water after filtration are 200,000 to 300,000 particle units. At the same time, the water flow is sterilized under ultraviolet light with a wavelength of 265 nm, and contacts the silver particle coating inside the filter element shell to enhance the sterilization effect. Step 2: Titanium dioxide photocatalyst for decontamination, chlorine removal and hydrogen production The water treated in the first step enters the storage space of the tubular shell. The tubular shell made of pure titanium material is subjected to high temperature 400℃ thermal oxidation treatment to form an oxide film containing semiconductor titanium dioxide photocatalyst. Under the irradiation of ultraviolet light with a wavelength of 380 nm, a photocatalytic reaction is carried out to remove chlorine in the water, decompose pollutants, and produce hydrogen. Step 3: Surface Plasma Resonance Hydrogen Small Molecules After the second step, the water is treated by external pressure and enters the second filter element from the outside of the shell. The pore size of the second filter element is 0.2 µm, which can filter out bacteria-level particles. After filtration, there are only thousands of particles in the water, reaching the drinking level. At the same time, the green light with a wavelength of 532 nm in the second filter element and the gold particles coated on the inside of the filter element shell undergo surface plasmon resonance, which modifies the water into small molecules and produces more hydrogen water, improving the functional effect of drinking water.

According to the present invention, the clean water obtained by the water purification process of the water treatment equipment of the present invention is defined as "titanium plasma hydrogen water", which is sterilized by ultraviolet light and silver particles, filtered by a filter element with a pore size of 0.2 µm, dechlorinated by titanium dioxide photocatalyst, deodorized and decomposed various pollutants, hydrogen molecule water by photocatalyst and surface plasmon resonance, and small molecule water modified by surface plasmon resonance.

The water treatment equipment of the present invention can be manually disassembled to clean the filter element and the inside and outside of the tubular housing by water flushing or ultrasonic cleaning. An electromagnetic induction valve is arranged inside the filter element to remind cleaning when the water pressure is set to less than 1 kg. An electromagnetic induction valve is also arranged inside the tubular housing to remind cleaning when the water pressure is set to less than 0.5 kg.
