Vehicle Purifier Solution
Car purifiers, also known as car air purifiers, car air purifiers, and car air purifiers, refer to air purifiers that are specially designed to purify odors, toxic and harmful gases, bacteria and viruses in the air in cars.
1. Types of car purifier solutions
1. Filter type car purifier
The filter-type car air purifier can effectively purify the dust, formaldehyde, benzene, bacteria and other harmful substances in the car, but the filter-type car air purifier only purifies the passively inhaled air, and the car air purifier due to the power Generally, there is not enough fan power to inhale and purify the air in the car. Therefore, the purification ability of the filter-type car air purifier is also limited, and the purification effect is effective.
2. Electrostatic dust collection type car purifier
The electrostatic dust collector car air purifier needs to cooperate with other equipment to achieve efficient purification effect, because the electrostatic dust collector car air purifier cannot completely absorb and eliminate odors, nor can it completely decompose toxic chemical gases. At the same time, its purification effect and purification efficiency will decrease with the accumulation of suspended particles, and the dust collecting plate needs to be cleaned frequently to restore its effect and efficiency, so the maintenance cost is high.
3. Ozone car purifier
The working principle of the ozone car air purifier is to generate ozone to purify the air in the car, so as to achieve the effect of improving the air quality in the car. Although, ozone has a certain effect on bacteria, especially against amines, nicotine, bacteria, etc. However, when using this type of car air purifier, proper attention should be paid to the concentration of ozone in the car, because if the concentration of ozone is too high, it will produce secondary pollution and cause harm to human health.
4. Plasma group car purifier
Pure ion group car air purifier is a car air purifier with patented technology. Use the net ion cluster generator to spray unique, efficient and safe net ion clusters to remove formaldehyde, benzene, bacteria, odors and allergens, etc.; special car technology for cars, using the Coanda effect, so that the net ion clusters can reach every room in the car The corners are purified; the ion generator needs to be replaced after about 60,000 hours of use.
2. The principle of the car purifier solution
Vehicle-mounted air purifiers are usually composed of high-voltage generating circuit negative ion generators, micro fans, air filters and other systems. Its working principle is as follows: the micro fan (also known as ventilator) inside the machine circulates the indoor air, and the polluted air passes through the air filter inside the machine (filtered twice) to remove or absorb various pollutants, and then passes through The negative ion generator installed at the air outlet (the high voltage in the negative ion generator produces DC negative high voltage during operation), continuously ionizes the air, generates a large number of negative ions, and is sent out by the micro fan to form a negative ion airflow to achieve the purpose of cleaning and purifying the air. There are also car purifiers with solar panels, which can run for a long time without being connected to electricity, and some latest technologies for removing pollution in cars, such as UFCO technology, etc.! There are many models of car air purifiers on the market, mainly composed of five purification elements, and their general functions are:
1. Ultra normal temperature formaldehyde catalytic oxidation technology (UFCO) scheme
The UFCO scheme uses soluble inorganic salts such as metal nitrates or carbonates to obtain metal oxides through oxidation and precipitation. A small amount of noble metal is supported on the metal oxide to obtain high formaldehyde oxidation activity at room temperature. The catalyst is mainly composed of metal oxides, and noble metal components are supported on the metal oxides. The catalytic activity of the catalyst is high and the duration is long. The conversion rate of formaldehyde of the catalyst of the invention can be as high as 100% within the range of effective working time.
2. Filter-type adsorption scheme
Use fans to force ventilation, and use porous filter materials, such as activated carbon, filter paper, fiber, foam, etc. (currently the filter material with the strongest adsorption capacity is HEPA), which is the standard high-density air required by the medical industry for air quality. The filter material absorbs suspended particles and harmful gases in the air, so that the car purifier can effectively filter suspended solids and a small amount of harmful substances, and has a certain degree of air pollution caused by odor, pathogenic bacteria, viruses, microorganisms and decorative materials. effect. Its structure is relatively simple.
3. Electrostatic dust collection scheme
Use fibrous activated carbon filter and electrostatic dust filter to purify the air. The principle of the electrostatic filter is to implant positive and negative permanent charges in the non-woven fabric fibers, so that the fabric surface is filled with high-voltage strong static electricity, which is used to absorb suspended particles in the air, so that harmful molecules can pass through the filter. When the net is absorbed in the filter, the cleaning efficiency of the filter can range from 7% to 95% for the filter core. Its structure is shown in Figure 1. First, the permanent mesh pre-filter traps dirty air and large particles such as hair and lint drawn in by the fan. Secondly, the high-voltage ionizer in the air purification filter of the air cleaner charges the pollutants in the air as small as 0.01 micron particles such as bacteria and viruses, and is adsorbed in the collection tray, which can prevent harmful irritants from Indoor circulation. Then, an activated carbon filter absorbs the odor. Finally, the purified air is returned to the cabin. The air purification filter can be easily renewed through regular washing.
4. Ozone sterilization program
Ozone (also known as triple oxygen), molecular formula O3, is the allotrope of oxygen. Ozone is the second strongest oxidant known to man after fluorine. Ozone can produce biochemical oxidation reactions with microorganisms such as bacteria and viruses at a certain concentration. Ozone has high energy, so it is very unstable, and its molecular structure changes easily at normal temperature and pressure, and it quickly decomposes into oxygen (O2) and a single oxygen atom (O). A single oxygen (O) has a strong activity and has a strong oxidation effect on microorganisms such as bacteria and viruses.
Ozone disinfection is a method of disinfection using the air-conditioning circulation system in the car. Using a special disinfectant to enter the circulation system can remove the peculiar smell in the car and has a certain effect of disinfection and sterilization, especially for amines, nicotine, bacteria wait. The ozone disinfection method is relatively simple to operate. A rubber hose connected to a special car disinfection machine is inserted into the compartment, and the car special disinfection machine is turned on. The disinfection machine sends high-concentration ozone generated by high-voltage discharge to every corner of the car. So it only takes a few minutes. Although the disinfection time is very short, the elimination of germs is more thorough. The fly in the ointment is that there will be a little ozone smell in the compartment after disinfection, but because ozone can be quickly decomposed into colorless and odorless oxygen, as long as the windows are opened for a while, the smell will disappear at all.
5. Negative oxygen ion freshening program
Gas molecules or atoms in the air form positive and negative ions under certain external conditions. Positive ions can cause insomnia, headache, high blood pressure and other adverse diseases in the human body; while negative ions are beneficial to human health. Negative oxygen ions can improve the function of the respiratory tract and lungs, and affect the human central nervous system and blood circulation system. When the human body inhales negative oxygen ions for 30 minutes, the lungs absorb 20% more oxygen and expel carbon dioxide by 14.5%. Lower blood pressure, improve heart function, purify blood, activate cells, improve sleep, and promote metabolism, so it is called "vitamin in the air".
The negative oxygen ion air purifier for vehicles uses high-voltage discharge to selectively ionize oxygen atoms in the air to generate negative oxygen ions. Negative oxygen ions have very active chemical properties. They can quickly combine with other compounds in the air to form new oxides, and then convert some gaseous substances into crystalline substances to purify the air.
The negative ion sterilization scheme is to simulate the principle of natural lightning to generate negative ions and ozone. Through the action of electronic circuits, the input low voltage is raised to DC and AC high voltage, and special components are discharged to ionize the air to generate negative ions and ozone. , and then generate active oxygen to improve and adjust the air, making the air more fresh and natural.
6. Catalyst decomposition principle
Photocatalyst is a substance that does not change itself under the irradiation of light, but can promote chemical reactions, just like chlorophyll in photosynthesis of plants. It is to irradiate the nano-sized TiO2 particles attached to the effective medium through a specific light source to produce an "electron-hole" pair (a kind of high-energy particle), and this "electron-hole" pair and the surrounding water, After the action of oxygen, it has a strong oxidation-reduction ability, which can directly decompose pollutants such as formaldehyde and benzene in the air into harmless and tasteless substances, and destroy the cell wall of bacteria, kill bacteria and decompose their silk mesh bacteria, thus To achieve the purpose of eliminating air pollution. The photocatalyst produces sterilization, anti-virus, deodorization, oil pollution decomposition, prevention of mildew, prevention of moss and algae under the irradiation of sunlight or indoor fluorescent lamps, and plays a powerful role in air purification. In general, photocatalysts must be irradiated by ultraviolet rays to function. If you can't get sunlight, if you want to activate the photocatalyst, you must add an ultraviolet lamp.
3. Advantages of the car purifier solution
1. Strong purification ability
Get rid of the desktop air purifier filter - the passive purification method, the active purification method of ion technology shows its efficient purification effect. Combining multiple filters to firmly absorb dust, the traditional passive purification method cannot purify every corner of the car, but ion technology can solve this problem, continuously spraying ions from the car air purifier, will reach Every corner of the compartment has a thorough purification effect.
2. Efficient sterilization ability
To achieve high-intensity sterilization, high-quality ion technology is required. General car air purifiers use silver ion purification technology and low-temperature plasma technology; advanced ones use negative ion technology and photocatalyst technology; and advanced ones use ion cluster technology.
3. Stylish appearance
Nowadays, the popular small appliances are no longer the elegant European and American styles, but the simple and fashionable Japanese style, and the same is true for car air purifiers, which are more popular in pure colors and fashionable appearance. Modern people who pay attention to practicality pay more and more attention to car air purifiers when choosing gifts. Whether it is a new home gift, wedding gift or business gift, car air purifiers have become the first choice.
