Description

 Fluid purification device  

A fluid purification device, and more particularly to a fluid purification device for increasing the specific surface area of a photocatalyst and prolonging the residence time of a fluid in a limited space.

In recent years, the issue of air pollution has received much attention because of its enormous negative impact on humans and the ecological environment. The substances causing air pollution may be solid particles, liquid droplets, or gases, naturally occurring soots such as volcanic eruptions, and pollutants generated by human activities, such as carbon monoxide or sulfur in exhaust gas from steam locomotives. Oxide, or gas emitted from the combustion of the factory, etc.

The main pollutants produced by human activities include:

1. Sulfur oxide (SOx): usually sulfur dioxide, the chemical formula is S02. SO2 is produced by volcanoes and other industrial processes. Coal and oil often contain sulfur, which produces SO2 when burned. SO2 is usually further oxidized by the oxidation of NO2 or the like to form H ₂ SO 4 , that is, acid rain.

2. Hydroxide (NOx): Nitrogen oxides, especially those produced by high-temperature combustion, can also be produced by lightning. They form brown smoke or pollutants that envelope the city. Nitrogen dioxide is a chemical with the formula NO2, the most famous air pollutant. This brown-red gas has a very pungent bitter smell.

3. Carbon monoxide (CO): CO is a colorless, odorless, non-irritating toxic gas. It is produced by incomplete combustion, such as natural gas, coal or wood. The exhaust gas emitted by cars or locomotives is the main source of carbon monoxide.

4. Volatile Organic Compounds: Volatile organic pollutants are common pollutants. They may be methane (CH4) or non-methane (NMVOCs). Methane is an extremely powerful greenhouse gas that causes global warming. Other volatile hydrocarbon organics are also important greenhouse gases because they produce ozone, prolong the life of methane in the atmosphere, and the effects vary depending on the air quality of the region. Aromatic non-methane benzene, toluene, and xylene are carcinogenic. Suspect, long-term exposure may lead to leukemia.

5. Toxic metals: such as lead and mercury, especially their composites.

6. Chlorofluorocarbons (CFCs): can destroy the ozone layer; the substances that produce this gas have been banned. These gases can be dispersed from air conditioners, refrigerators, sprays, etc., and chlorofluorocarbons enter the air and rise to the stratosphere. They react with other gases, destroying the ozone layer, causing harmful ultraviolet rays to reach the surface of the earth, causing skin cancer, eye diseases and even damage to plants.

Seven, free radicals: an airborne particle, related to cardiopulmonary disease.

8. Ammonia (NH3): mainly from the process of agricultural activities, the chemical equation of ammonia is NH3, usually a irritating gas, the relevant nutrients needed for ground crops, ammonia is the leader of fertilizer and nourishment, whether it is Direct or indirect, ammonia is a synthetic component of many drugs. Although ammonia is used in a large amount, it is corrosive and injurious. In the atmosphere, ammonia reacts with hydroxides and sulfur to form particles.

9. Odor is released from garbage, sewage and industrial processes.

X. Radioactive waste: produced by nuclear explosions, nuclear events, war blasts and natural processes such as radioactive decay of plutonium.

These are the main pollutants and their sources.

Among them, nitrous oxide (N2O) is the most abundant hydroxide in the atmosphere, and it is also the most chemically stable of nitrogen oxides. Because it has no direct harm to the human body, it is not like other nitrogen oxides such as NO or NO2 has received attention, but its severe destruction of the ozone layer has been confirmed.

In 2015, the United Nations held a climate summit in Paris. The topic was to "inhibit global warming". The goal is to reduce greenhouse gas emissions year by year, so that the earth's warming rate will slow down in 2100, and global temperatures will not rise more than 1.5. °C [2015 UN Climate Summit, Wikipedia]; Although the standards for greenhouse gas emission reductions submitted by countries vary, the reduction of greenhouse gas emissions is an established consensus. The US Environmental Protection Agency (USEPA) lists six gases for emissions reductions, including carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. China adopted the "Greenhouse Gas Reduction and Management Law" in the 8th and 16th Third Reading of the 8th Legislative Yuan of the Legislative Yuan in 2015. In July of the same year, the President promulgated and implemented the regulations. The next year, the Environmental Protection Agency drafted the implementation rules for the follow-up promotion, of which Article 12 Xiang Mingding "Greenhouse Gas Statistics and Emissions Trends in the Industrial Process and Product Use Sector"; therefore, there are quite a number of process gases in the semiconductor industry such as nitrous oxide, methane, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride. It will be subject to regulation and inventory. For the industry, it is undoubtedly necessary to deal with it in advance to avoid being regulated.

Common greenhouse gases have different effects on global warming (called global warming potential GWP100), C0 ₂ is 1, SF ₆ is 22,800, and N ₂ O is 280; in addition, N ₂ O is also The main gas that destroys the ozone layer of the atmosphere is mainly because N ₂ O has strong absorption capacity for vacuum ultraviolet (Vucuum UV, VUV) and decomposes into N ₂ and O atoms, so that O atoms react with ozone O ₃ to form O ₂ . The ozone is reduced, and its chemical formula is: N ₂ O+hv→N ₂ +O; and another chemical formula: O+O ₃ →2O ₂ .

In addition, issues such as PM2.5, which is quite famous for the current air pollution problem, are issues that are currently being dealt with.

Therefore, there are many air quieting equipment or water purification treatment equipments, etc., all of which are expected to improve the various pollution problems mentioned above. At present, the most commonly used photocatalyst technology has been actively developed and applied in the past 20 years, but it is still limited by photocatalyst. It requires light to have its own effect, especially ultraviolet light, and the pollutants must be exposed to the photocatalyst to be redoxed and effective.

The supply space 101 is formed by an outer ring wall 103 having a fluid input port 104 and a fluid output port 105. A flow guiding structure 20 is disposed between the inner ring wall 102 and the outer ring wall 103. For guiding a fluid from the fluid input port 104 to the fluid output port 105 in a single flow direction, wherein the flow guiding structure 20 is composed of a metal material containing foamy pores, according to which the flow can be of the same size. There is a higher specific surface area within the space 101.

At the same time, the metal material selected may be composed of a material containing one of nickel, copper, or iron or an alloy, considering the cost or convenience of forming.

A sintering method, a fiber metallurgy method, a casting method, a sintering method, or a sputtering method, etc., and a preferred form is an open-cell foam metal in which pores are in communication.

In this embodiment, the flow guiding structure 20 is composed of a plurality of first guiding layer 201 coated with a photocatalytic hollow disk and a second guiding layer 202. The first guiding layer 201 is from the inner annular wall. The outer wall 103 extends and retains a predetermined gap, and the second guiding layer 202 extends from the outer ring wall 103 toward the inner ring wall 102 and retains a predetermined gap. Here, the first guiding layer 201 and The second conductivity layer 202 is arranged in an interleaved manner. Here, it should be particularly noted that the flow guiding structure 20 is plated with a photocatalyst and is interleaved with the first flow guiding layer 201 and the second guiding layer 202, and has the same size as the conventional cleaning machine. In the flow space 101, the purification effect and the treatment efficiency of the fluid purification device 1 of the present invention are both higher than that of the conventional purification device by 30% or more.
