Description

Filter structure for filtering air by wind generated by vehicle travel

The invention relates to a filter structure, in particular to a filter structure that can be assembled on a car body and uses the wind generated by the forward movement of the car body to filter air without consuming additional energy.

Check, Atmospheric particulate matter refers to solid particles or droplets suspended in the air, whose composition mainly depends on its source, and is briefly explained as follows: (1) The dust rising from the ground contains oxides Minerals and other ingredients; (2) sea salt, whose composition is similar to that of seawater; (3) particles produced by natural processes, mostly from volcanic eruptions, sandstorms, forest fires, sprays, etc .; (4) from sulfur and Nitrogen oxides are converted, most of which are caused by human combustion of fossil fuels (such as coal, petroleum) and garbage; (5) For indoors, dust mites and second-hand smoke are the main sources of suspended particles Secondly, the burning of gold paper, incense and burning of mosquito coils, etc. will also generate suspended particles.

At present, many studies have confirmed that suspended particles can cause damage to the respiratory system and the cardiovascular system, leading to asthma, lung cancer, cardiovascular disease, birth defects and premature death. After all, the diameter of suspended particles determines their ultimate impact on the human body. In the respiratory tract, usually larger diameter suspended particles are filtered by cilia and mucus, and cannot pass through the human nose and throat The larynx, however, suspended particles with a diameter of less than or equal to 10 micrometers (μm) can enter the human respiratory system, which is also called "respirable suspended particles" (PM10 for short), and PM10 can penetrate the aforementioned barrier and reach the human body Bronchus and alveoli, and suspended particles with a diameter less than or equal to 2.5 micrometers (also known as "fine suspended particles", referred to as PM2.5), because of easy adsorption of toxic substances (such as: heavy metals, toxic microorganisms .. Etc.), and can reach the bronchiolar wall, and interfere with the gas exchange in the lungs, and even pass through the cell membrane to other organs (such as the brain), it can be seen that suspended particles have a huge impact on health.

Generally speaking, PM10 will fall to the ground within a few hours due to the effect of gravity. However, PM2.5 will suspend in the air for a long time until it adheres to the rain and settles to the ground. PM2.5 can be in the atmosphere It stays for a long time and can enter the body as the human breaths, and it accumulates in the human trachea or lungs, so it will seriously affect people's physical health. Therefore, PM2.5 has become an emerging pollutant of high concern worldwide. The WHO has also proposed very strict PM2.5 standards for countries, that is, the annual average concentration standard is 10 μg / m3, and the daily average concentration standard is 25 μg / m3. However, most cities around the world have failed to meet the aforementioned standards. Although there are many manufacturers designing filtering devices that can filter PM2.5, the aforementioned filtering devices are usually fixed to a specific area and cannot be moved arbitrarily, meaning that the filtering device can only filter air in a specific area. It does not help the increasingly serious air pollution problem. Therefore, how to propose a good solution to the aforementioned problems has become an important issue to be solved by the present invention.

In addition, a predetermined height is accumulated in the receiving space of the body. Filter liquid, the other end of the air inlet pipe will extend into the filter liquid, and the air inlet pipe is adjacent to the other end, at least one opening is opened, and the air flowing out from each of the openings can be connected with the filter liquid. Mix and perform wet filtration, and the second filter is assembled to the body corresponding to the air outlet to perform a second dry filtration on the air that has passed through the wet filtration and flows out of the air outlet, Among them, the mesh number of the second filter More than the number of meshes of the first filter. In this way, the filter of the present invention can achieve the effect of filtering suspended particles only by using the wind generated when the vehicle body is traveling, and the filtered air can be discharged back into the filter. In the atmosphere, which in turn improves air quality.

Another object of the present invention is that the filter structure further includes a fine-bubble filter element, wherein the fine-bubble filter element is provided between the liquid surface of the filter liquid and each of the openings, or is assembled to a corresponding one of the The position of the openings, so that the air bubbles formed by the air flowing out of the openings are blocked by the fine-bubble filter element and broken into smaller volumes of air bubbles.

There is an accommodation space 110 inside, and an air outlet 112 is provided on the top surface of the accommodation space 110. The air outlet 112 can communicate with the accommodation space 110, and the accommodation space 110 can store a filter liquid 111 of a predetermined height. However, the liquid level of the filtered liquid 111 will be lower than the air outlet 112. In this embodiment, the filtering solution 111 can contain sodium bicarbonate (NaHCO ₃ ) (or soda powder), and the weight percentage of the sodium bicarbonate (NaHCO ₃ ) in the filtering solution 111 is 0.5 to 1%. In addition, the filtering solution 111 can also include ammonium phosphate, and the proportion of the ammonium phosphate in the filtering solution 111 is about 1 to 1 liter of water, so that about 3 to 10 grams of ammonium phosphate is dissolved. Thus, when air enters the filtering solution 111 After that, the included nitride will react with the filtering liquid 111 and be filtered out. However, in other embodiments of the present invention, the industry can also adjust the composition of the filtering liquid 111 according to actual needs. In addition, Because ammonium phosphate is a compound produced by phosphate and ammonium ions, it can be divided into normal salt ((NH ₄ ) ₃ PO ₄ ) and hydrogen phosphate di Ammonium ((NH ₄ ) ₂ HPO ₄ ) or ammonium dihydrogen phosphate (NH ₄ H ₂ PO ₄ ), etc.

Please refer to FIG. 1 and FIG. 2 again, the air inlet pipe 13 is assembled to the main body 11, and an air inlet 130 is opened at one end thereof. The air inlet 130 is located outside the main body 11 and is exposed on the outside. Outside the vehicle body 2 and facing the windward side of the vehicle body 2 (that is, the direction in which the vehicle body 2 travels, as shown in FIG. 1), the other end of the intake pipe 13 extends into the body 11. The accommodating space 110 is located in the filtering liquid 111. Among them, the intake pipe 13 is adjacent to the other end and is provided with a plurality of openings 131. Since the openings 131 are located in the filtering liquid 111, Below the liquid surface, when the external air flows into the air inlet pipe 13 through the air inlet 130, it will flow out from the openings 131 and form a bubble shape. At this time, the filter liquid 111 will be in phase with the air bubble. Mix to wet-filter the bubble, that is, the suspended particles and impurities included in the bubble will be wetted by the filter liquid 111 and stay in the filter liquid 111. At the same time, the bubbles contained in the bubble will remain in the filter liquid 111. The nitride will also react with the filter liquid 111, and also stay in the filter liquid 111, so that the air leaving the filter liquid 111 is cleaner net. In particular, although the opening 131 shown in FIG. 2 is located above the other end of the intake pipe 13, In other embodiments of the present invention, the supplier may also open the opening 131 below or adjacent to the other end of the intake pipe 13 as long as the opening 131 is located below the liquid level of the filtering liquid 111.

In addition, please refer to FIG. 1 and FIG. 2 again, the first filter screen 15 is assembled to the intake pipe 13. In this embodiment, the first filter screen 15 is assembled to the intake pipe 13. At the position of the air inlet 130, when the outside air flows into the air inlet pipe 13, the first filter screen 15 can perform the first dry filtration and block the relatively large suspended particles or impurities in the air. In other embodiments of the present invention, the first filter screen 15 is not limited to the aforementioned position, but can be assembled to any position of the intake pipe 13 as long as the first filter screen 15 does not touch the filter. Liquid 111, and can perform the first dry filtering on the air flowing into the air inlet pipe 13, which is the assembly position of the first filter screen 15 referred to in the present invention. Furthermore, the second filter 17 is assembled to the position of the body 11 corresponding to the air outlet 112, and the number of meshes of the second filter 17 will be greater than the number of meshes of the first filter 15. When the wet-filtered air flows out of the air outlet 112, the second filter screen 17 performs a second dry-filtering to reduce smaller suspended particles and impurities in the air (that is, Sub-dry filtration and wet filtration). In this embodiment, the second filter 17 is a High-Efficiency Particulate Air filter (HEPA) filter, which means, The second screen 17 is capable of filtering at least 99.97% of particles in the air having a diameter of not less than 0.3 micrometer (μm) in accordance with the HEPA standard.

Please refer to FIG. 1 and FIG. 2 again. When the vehicle body 2 is moving, the wind generated by the vehicle body 2 will automatically flow into the filter 1 with air. At this time, the first filter 15 will The first dry filtration is to remove larger suspended particles and impurities in the air. Alas, when the air flows into the filtering liquid 111 through the air inlet pipe 13, the filtering liquid 111 will wet filter the air so that Some suspended particles and impurities in the air stay in it. At the same time, the filter liquid 111 will also interact with the air. The nitrides in the reaction react to filter out the nitrides. Finally, before the air leaving the filter liquid 111 flows out to the filter 1, the second filter screen 17 performs a second dry filtration on the air to remove the air. Small suspended particles and impurities in the air, so that the air discharged through the filter 1 will be extremely clean, and the amount of suspended particles in the air can be reduced. In summary, it can be seen that the filter 1 of the present invention does not require additional electricity or other energy at all, and only needs to use the wind generated when the vehicle body 2 travels, so that the outside air can automatically flow into the filter 1 to achieve The effect of filtering suspended particles. At the same time, the filter 1 will discharge the filtered air back into the atmosphere. Since the vehicle is already a major means of travel for people, and there are many, the filter 1 of the present invention, As people go to their destinations, they can simultaneously purify the air, thereby improving the air quality. That is to say, the filter 1 of the present invention has the effect of filtering the air in a specific area, which is of great help in reducing air pollution.
