Tobacco smoke removal and purification system

Abstract

Tobacco smoke is a nuisance not only for smokers, but also because the smoke directly emitted from the cigarette fills indoor spaces, creating an unsanitary environment. Furthermore, when this smoke is released onto public roads, it is a nuisance to pedestrians and residents, and is harmful to their health. Although much research and consideration has already been conducted, a solution has not yet been reached. [Solution] First, to increase the surface area of ​​the catalyst, the support material was nano-sized using amorphous materials. In addition, to correct the degradation of the catalyst due to changes over time, the catalyst was moved to ensure that a constantly refreshed surface was obtained. We have developed a method for removing particles by utilizing the hydrophilic groups due to the polarity of water. Furthermore, we have also developed a method for treating hot particles that prevents recombination, resulting in completely clean air, eliminating pollution to the outside, and enabling hygienic treatment.

Description

Technical Field

[0001] Currently, the smoke of cigarettes is simply discharged to the outside through a ventilation fan. However, the exhaust is not complete, and the exhausted smoke is only scattered on the surface roads, and the structure is such that not only the smokers' room but also people walking outside are made to inhale the scattered smoke. This is the technical field of removing this smoke. If this smoke can be removed, people walking on the external roads do not have to inhale dirty air such as smoke, and the air and the town can be made clean towns without the harmful effects of smoke. The present invention aims to collect the smoke in the smokers' room, pass it through a space with water droplets such as water vapor or rain, and attach or dissolve the unnecessary particles of the smoke to the vapor mist or water droplets by hydrogen bonds or the like and remove them by dropping them together with water from the space. Also, by passing through the space of cooling air or cooling water, the molecules expanded by heat are cooled, and the water droplets or cold droplets to which the smoke adheres are collected and dropped to remove them, which is an analog method. The present invention aims at purification by a combination of a digital method by improving a method such as a catalyst for the purpose of removing chemical substances targeting aldehyde and specific molecules discharged from the room inside the equipment, or a single method. It has been reported that iron in which amorphous is precipitated in still water developed by Mr. Taguchi et al. consists of nanoparticles and fibrous and is formed like a lump of cotton. Such a material may be oxidized to make iron oxide that becomes a catalyst of Fe2O3, or a gas such as TiO2 may be deposited like CVD to form an amorphous film to constitute a catalyst of nanoparticles. The radius of spheres such as beads is 1 mm even at 10 -3 m, but in the case of nanoparticles, it is 10 -9 m, so it is 10 -6 smaller than the bead balls. Therefore, roughly speaking, when comparing the surface areas, it is 10 6The area of ​​contact with suspended particles increases by a million times. Not only does this increase the effectiveness of the catalyst, but it can also be used for extended periods without being poisoned by contact with particles or losing its activity. Catalysts using aluminum oxide particles are already being considered. To prolong the time-dependent changes in the catalyst, it is designed in sheet or cassette form so that a fresh supply of catalyst is constantly available. This invention is not only used to remove tobacco smoke particles through a filter, but also to remove impurities from wastewater, aiming to discharge the cleanest possible water. Activated carbon is also highly effective for water filtration. Among activated carbons, coconut shell carbon, made from coconut shells, is being investigated for its practical advantages, such as its small size, porous structure, and good performance. Using other materials such as zeolites can further enhance effectiveness. [Background technology]

[0002] Currently, the only method used is to run the ventilation fan to expel the dirty air from inside. In areas where the ventilation is incomplete, smoke fills the interior, creating a poor sanitary environment. Even when ventilation is performed, it simply releases smoke, dust, and in some cases, pathogens outside, causing passersby to inhale and contaminate this dirty air. They may think they're making things look clean, but in reality, the air is hardly being purified at all. Even if the exhaust is released onto the street, passersby may inhale some of the smoke or some of the polluted air from the rooms, which is unsanitary. [Prior art documents] etc. [Patent Documents]

[0003] To purify the air, systems that utilize filters, chemicals, photocatalysts, activated carbon adsorption, and electrostatic adsorption in conjunction with ventilation fans are also being considered. The filter can become clogged with dirty particles and debris, rendering it ineffective, or it may need to be replaced frequently. While some rooms have air purifiers, they are typically floor-mounted and therefore not effective against airflow that causes smoke, like cigarette smoke, to rise into the air and fill the room. Some systems use catalysts or activated carbon for smoke removal, but over time, their ability to capture smoke and particles weakens, or they become poisoned by the captured film, resulting in a loss of effectiveness. Catalysts with small surface areas, in particular, lose their activity very quickly. In addition to being executed Many studies have been conducted on ventilation, smoke reduction, and odor removal for cigarette smoke. Basically, methods include treatment or removal using chemical substances, particle adsorption methods using activated carbon or charged materials, and cleaning using photocatalysis with titanium dioxide and UV irradiation. These methods are all imperfect; particles that appear to disappear regenerate within a certain temperature range, and the catalytic effect does not last, meaning that the regeneration and recombination of various gases cannot be completely prevented. Furthermore, UV light is harmful to the human body. Therefore, the present invention aims to devise and put into practical use a method and system for removing various harmful and unwanted substances by utilizing natural phenomena with adhesive and dissolving properties, such as hydrogen bonding and oxygen bonding of water (H2O), without using many chemicals. We will also improve the weaknesses of technologies that have already been considered. Examples of references 1. Filtration of tobacco smoke Yoshio Otani Smoking Science Research Foundation 2.

However, the problem is that reports indicate that while catalysts and activated carbon, which act as active materials, may be effective initially, their effectiveness diminishes over time, and as a result, long-term use or solutions have not yet been achieved. Therefore, based on the present invention and our research, we present a method that exhibits long-term effectiveness and can be used. The first method utilizes current technology to sustain activation over a long period of time by supplying sheets to which the catalyst and supported medium particles are attached in small increments via rotation or intermittently, thereby moving and winding the encapsulated and poisoned catalyst. The second method involves increasing the surface area by using even smaller particles for the support that holds the catalyst. This involves using amorphous nanoparticles or fibers of the transition metal iron, and either directly oxidizing them to use as a catalyst, or by depositing a conventional TiO2 film or the like onto these particles (CVD) to create a huge surface area, increasing the contact surface with the gas, reducing degradation and poisoning, and further extending the effect of surface movement. The third method is a cleaning method that is closer to natural phenomena than the chemical methods mentioned above, and has hardly been considered until now. Compared to the former method, it can be called an analog method: water washing, cooling, and freezing. Everyone knows that after it rains, frosts, or snow and ice freeze onto the trees, the air becomes clear and pure. This phenomenon occurs because raindrops, fog, frost, snow crystals, etc., attach to impurities and particles in the air through hydrogen bonding with water, and then fall or adhere to these particles, removing them from the air. This is due to the adhesive and dissolving power of water, as well as the chemical bonding caused by the positive and negative charges of hydrogen and oxygen. By constantly reproducing this phenomenon within the purifier of this invention, almost all particles other than air are removed, and since they are washed away with water, recombination does not occur at that point. The chemical reaction is caused by temperature T as described above, and is shown by Boyle's Law and Charles's Law PV=nRT, indicating that particle activity can be inhibited by temperature. Because of the interconversion and interactions between particles and gases, and because these changes over time and depending on the state, it is difficult to completely remove them. In one example, acetaldehyde and ethanol took 40 minutes to transition from the gas phase to particles. Even after filtering, there have been instances where high concentrations of 0.3 μm (300 nm) particles remained in certain areas. Even with a 10-fold dilution from bystream smoke vapors, particle generation still occurs, and new particulate matter is effectively suppressed when particulate matter is already present. In other words, there are instances where a saturated state is established. To remove both particulate matter and gaseous substances simultaneously, it is necessary to be able to handle cigarette smoke with an average size of 0.1 μm (100 nm). To meet this requirement, Activated carbon fiber ACF filter Charge it to increase the adsorption rate. It adsorbs chemical substances. It has been found that adsorbing aniline is effective in removing aldehydes. These have already been considered. Furthermore, there are reports that cigarette smoke contains 100 ppm of CO. On the other hand, the adsorption of smoke and particles by water for the improvement of this invention is easily achieved through hydrogen bonding due to the polarity and gaps of water's hydrogen and oxygen. As a result, it easily combines with the oxygen and hydrogen contained in acetaldehyde and ethanol in cigarette smoke, and incorporates them, thus removing these particles. Furthermore, water itself has no effect on the human body, and treating the contaminated water is not particularly difficult. With such a system and functionality, it would be possible to eliminate cigarette smoke, air pollution, viruses, and other airborne particles almost permanently. Depending on the purpose, dissolving soap or synthetic detergent in the water before use can further enhance the cleaning effect. This invention utilizes the fact that water is polar and has hydrophilic groups to remove particles containing aldehydes. As shown in the above diagram TIFF2026104730000002.tif57158 van der Waas intermolecular forces +δ and -δ charges due to intermolecular forces and hydrogen bonds The suction force dissolves ethanol in water. This demonstrates the principle of removal along with water. As described above, the objective is to invent, improve, and provide a system that digitally targets harmful substances and addresses them with long-term chemical countermeasures, while simultaneously removing tobacco smoke, viruses, bacteria, dust, etc., through natural, allergic countermeasures. Problems the invention aims to solve

[0004] Even smokers face restrictions on where they can smoke, and currently, they smoke in environments where the smoke they inhale affects others. Furthermore, even in locations where smoking rooms are provided, the smoke is only exhausted; the tobacco smoke is not removed or collected. In floor-standing devices like air purifiers, some air particles are filtered out at the bottom, but lighter smoke that rises into the air doesn't easily descend or circulate. Furthermore, the filters need to be replaced frequently. It is best to remove the air that rises into the atmosphere with a ventilation fan, but fine particles like smoke either pass through the filter or clog it. Therefore, the filter needs to be replaced frequently. Also, as mentioned above, it has been reported that both catalytic and activated carbon purification methods lose their effectiveness over time. If the ketone group CHO of aldehydes is further oxidized to the acetate group COOH, they become harmless, but the effect of catalysts is not clear. Means to solve the problem

[0005] After it rains, the air outside becomes cleaner and more refreshing. The same is true on mornings when it snows or frosts. This is because rain and fog attract or absorb dust and dirt from the air, causing them to fall and be carried away. Additionally, water droplets and moisture in the air float in the air, dissolving any dust and dirt that may have attached to them, and then freezing and settling on shrubs, plants, and the ground, resulting in clean air. If such analog means can be artificially created in the middle of the airflow before ventilation, removing and recovering smoke and polluted air without contaminating people or houses, and providing clean air to people walking on public roads outside the house, it would be desirable from a hygienic standpoint, and smokers could smoke with peace of mind. Furthermore, in using a catalyst, which can be considered a digital method, in order to slow down the change over time and maintain activation for a long period, we also investigated digital methods to improve the long-term effectiveness of the catalyst by using nanoparticles as a carrier and supporting the catalyst on its surface. In this invention, we also investigated methods to prevent catalyst degradation due to changes over time, such as sequentially supplying new catalysts, and report these findings. In addition, for viruses such as coronavirus and bacteria, methods that destroy them with the killing power of metal ions, etc., can be used in conjunction with the catalyst to improve overall cleanliness. Effects of the Invention

[0006] By implementing this invention, it is possible to clean not only cigarette smoke but also the entire polluted air, making it effective against infectious diseases like COVID-19 and airborne viruses, thus offering a double benefit. Furthermore, by passing air through a mist or water droplets mixed with soap water or disinfectant, artificial rain, or a cooling chamber, the air is cleaned. This water is either drained into the sewage or the drainage liquid is purified and recovered using filters, ions, activated carbon, etc., which not only makes the air cleaner but also more hygienic. Smokers can enjoy smoking comfortably without feeling inhibited. The air exhausted outside also becomes clean air, eliminating the need for frequent filter replacements, and waste and dirt can be managed, thus maintaining a hygienic environment.

Embodiments for Carrying Out the Invention

[0008] The present invention will be described with reference to the drawings.

[0009] FIG. 1 is a perspective view of an integrated device for removing tobacco smoke and contaminated air of the present invention. When tobacco smoke particles float into the air, and the main body of the purification device of the present invention (box 1) uses water to capture the smoke and particles, if it is undesirable for water to splash out even inside the case, Figure 7 shows a system in which a porous cloth soaked in water is constantly replaced, and a new cloth and water are supplied. The air is drawn into the intake (window) 2. This airflow is generated by fan F, a standard ventilation fan. Normally, a grate is installed to prevent hands or other objects from directly reaching it. Next, the dry section 3 of the present invention, which is a smoke particle and contaminant particle filter section using a nanoparticle catalyst sheet, is shown as a type in which only the sheet and winding are replaced, and a cassette type (Figure 6(c)) in which the entire unit is replaced at once, with the active material sheet (Figure 3), which will be described later, being automatically supplied, unfolded, and wound up. While dry methods alone may be sufficient in some cases, this invention also goes further, similar to natural purification, by using analog method 4 to create water droplets, mist-like water particles, as well as ice-like, snow-like particles and floating bodies to remove particles as airborne impurities, thereby removing any remaining particles, or by removing impurities from the start using water droplets or ice droplets without any dry methods. As several reports have indicated, dry filtration methods are not suitable for long-term use, and that gases and particles that have been removed recombine and reappear, making complete removal impossible. This does not guarantee that any particles will disappear as long as temperature T persists, even if PV=NRT (Percentage Value = No Return on Time). Therefore, as long as a high temperature state exists, the chemical reaction will continue. To prevent the chemical reaction from occurring, the air and particles are cooled, and the expanded particles are reduced in size, losing their buoyancy and falling, and combining with water to prevent recombination and chemical reactions. Furthermore, by utilizing the adhesive force due to the polarization of water molecules and the dissolution of particles due to the spaces between water molecules, it is possible to remove harmful particles contained in smoke, such as acetaldehyde, and even smaller particles of the 100nm class, like those found in cigarette smoke. To create this situation, a water spraying unit 4 is installed to cause suspended particles to adhere to or dissolve in water particles, and by spraying raindrops or mist-like water particles onto incoming suspended particles, most of the particles are removed. It can also be operated as a fine mist, like a humidifier. In the case of cigarette smoke, the particles are high in temperature and swollen, so basically, when cooled they become smaller particles and lose their buoyancy. Larger molecules will fall, but small ones like cigarette smoke do not fall easily. Therefore, as shown in section A of Figure 1, allowing raindrops or mist to pass through, or a misty space, is a win-win situation, as it can attract and remove any kind of particle. Furthermore, impurities that float and regenerate in the air at a certain temperature are cooled to suppress recombination and regeneration, and residual moisture in the air is also removed by passing them through a cooling section 5 that creates ice droplets or crystals in a freezing section. This removes all of the contaminants, but a dehumidifier 6 is installed to prevent cold air from leaking outside, and finally, the exhaust fan F2 exhausts the air to the outside, allowing clean air to be discharged. Figure 1(b) shows the section where moisture and impurities are removed from the air by the cooling section 5. This section removes fine particles and suspended particles that did not adhere to and dissolve in the water, along with any remaining moisture, by freezing or snow-forming. Furthermore, as ice accumulates in this area, at night, when no smoke is being emitted and everyone is asleep, the accumulated ice is thawed with a heater and drained along with any attached dirt to ensure no ice or dirt remains. Furthermore, it indicates that a dehumidifying filter will be installed in the final stage to prevent cold air and some mist-like ice droplets from leaking out during use and to remove moisture. Next, moving to Figure 4, we see a water receiving and filtering container in a system where harmful substances or dirt mixed with raindrops are filtered, clean water is discharged, and this clean water is then reused to eliminate water waste and maintain environmental friendliness. This saves water and prevents environmental pollution. Figure 2 shows the distribution of each separate function within the vessel of the present invention. This supplements the explanation of Figure 1. In the diagram, cigarette smoke S is guided by a ventilation fan F1, and harmful substances and odor-causing organic matter and particles such as aldehydes are removed by a chemical catalyst 3. Chemical processes are considered digitally. Methods like applying an electric charge or using activated carbon are treated as individual solutions. Separately, in a manner similar to natural phenomena, almost all impurity particles are removed using an analog method by utilizing water droplets (raindrops) or mist-like water droplets. These particles adhere to and dissolve through space, fall, and then pass through the water spraying unit 4 so that they can be washed away with water. If fine particles or chemical substances at a certain temperature remain, a cooling unit 5 is provided to stop the activity of the particles and cause them to adhere to ice droplets. It is assumed that particle capture is almost complete at this stage, but a moisture absorption section 6 is provided to prevent moisture-laden cold air or cool air from leaking to the outside, and the air that passes through this section flows to the outside, so that clean air is released to the outside, with cigarette smoke completely removed as well as other viruses and debris. Figure 3(a) proposes a mechanism that, despite current studies and achieving catalytic effects, prevents practical application due to catalyst degradation or poisoning over time. This mechanism involves creating a sheet-like catalyst array, supplying it as needed, and ensuring a constantly activated catalyst. This method allows for the creation of a sheet-like catalyst by spraying metal particles such as TiO2 or Al2O3 using CVD or vapor deposition, similar to how amorphous solar cells are manufactured. Furthermore, Figure 3(b) shows that, as demonstrated by Taguchi et al., amorphous iron nanoparticles and nanofibers are produced in still water, and can therefore be used directly as iron oxide catalysts, or other catalysts, such as titanium oxide, can be supported on them. Alternatively, amorphous iron nanoparticles or nanofibers may be directly attached to a sheet and titanium dioxide may be deposited onto them using a CVD (Chemical Vapor Deposition) method to construct a catalyst sheet. Alternatively, iron nanoparticles or nanofibers may be oxidized to construct a catalyst using iron oxide (Fe2O3). The oxides used as catalysts here include transition metals from the fourth period (and beyond), including TiO2, such as Mn, Cu, Fe, Co, Ni, Cu, and Zn, and many catalysts are made from oxides of these metals. Figure 5 illustrates several examples of how, when a single catalyst sheet as shown in Figure 3 is insufficient to remove cigarette smoke, multiple sheets can be used to create multiple air passages or extend the distance between them to increase the contact rate with the catalyst and further remove harmful or unwanted particles from cigarette smoke. Figure 5 shows a method for removing unwanted particles by increasing the opportunities for contact with the catalyst through a zigzag passage using a sheet to which nanoparticles are attached. Figure 6 shows that by creating multiple air passages, the catalyst has many opportunities to come into contact with the air even as a large volume of air passes through, and because fresh catalyst is constantly fed from the rotor (roller), the catalytic function can be used without any decrease in performance. The sheet can be automatically and continuously or intermittently wound up and fed using a stepper motor or the like, ensuring safe and convenient operation. Figure 6 shows an example in which the rollers and other components that supply the catalyst sheet are compactly packaged into a cassette, and by replacing it as needed, it can be used almost indefinitely. This is an example of the dry method of the present invention, and although only the catalyst sheet is described, the range of applications is limitless. It is also possible to use activated carbon, attach coconut shell carbon, or, if necessary, attach metal ions such as silver ions or copper ions to form a mesh. We have reviewed and improved upon the limitations of dry filtration methods, which had previously been hampered by catalyst degradation and activated carbon deterioration over time. Furthermore, we have developed a unique system and invention that purifies cigarette smoke and air through one or a combination of methods, including particle removal using natural analog phenomena that had not been extensively considered until now. Furthermore, for the benefit of smokers, Figure 8 shows a method to remove nicotine and tannins, and to protect health by removing not only the filter but also harmful particles, by attaching a catalyst made of oxidized harmless iron amorphous nanoparticles to the filter or installing it in the smoke passage. Even if the iron flakes off and is inhaled or dispersed into the air, it is harmless to humans. Potential for industrial use.

[0010] Methods for cleaning the air in a room include simply ventilating and releasing the polluted air outside, removing polluting particles through filters, or using methods like air purifiers that charge airborne particles and cause them to adhere to metals, thereby releasing metal ions for sterilization. These can be described as digital, dry methods. This invention utilizes a wet cleaning method using water, which can be described as a natural air purification method, and is in line with the principles of nature. It can be called an analog method. Furthermore, the chemical method has also been improved, and by controlling the surface area at the nano level and continuously supplying new catalysts, we are considering the removal of chemical substances, which are the main components of smoke, in a continuous and sustained manner. Therefore, it can be applied to smoking rooms, coffee shops, convenience stores, cafes, places where people gather, offices, factories, etc., has a wide range of applications, is hygienic for the public, and makes a significant social contribution and industrial advantage, including exhaust, waste, and recovery.
