Detailed ways

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Please refer to FIG. 1 and FIG. 2 , the present invention provides a vehicle-mounted chemical filter, including a filter box body 1, the filter box body 1 includes a filter body 11 with an accommodating space and a filter body 11 that covers the filter body 11. The net cover 12, wherein: the filter body 11 is fixedly installed with a coarse filter layer 2, an antibacterial layer 3, a high-efficiency particle filter layer 4, a chemical purification layer 5 and a high-efficiency selective adsorption layer 6.

It should be noted that the first layer: the coarse filter layer 2, which is used to filter larger particles such as hair dust when the machine stops working, so as to protect other functional layers inside the filter body 11; the second layer: antibacterial layer 3, It is used to sterilize and antibacterial to protect the environment inside the car: the third layer: high-efficiency particle filter layer 4, the removal efficiency of fine particles such as PM2.5 reaches more than 99.7%; Obvious removal effect; fifth layer: high-efficiency selective adsorption layer 6, which has a significant effect on common toxic and harmful gases in the car such as formaldehyde, benzene, xylene and other VOCs.

Referring to Figure 3 and Figure 4, specifically, the high-efficiency selective adsorption layer 6 is filled with spherical and granular filter materials, and the high-efficiency selective adsorption layer 6 is prepared by a mixed chemical filter material, which can quickly, efficiently and stably adsorb The target gas is processed, and the service life of the product is improved. Its composite filter material includes potassium permanganate alumina balls and coconut shell activated carbon. Potassium permanganate alumina balls and coconut shell activated carbon are layered and tiled. Compared with the traditional way, the layered tiling mode can greatly reduce the wind resistance of the product, so that the wind resistance is less than 75Pa under the condition of 0.74m/s. Among them: Potassium permanganate alumina ball is an environmentally friendly chemical adsorption material with a wide range of uses. It uses the strong oxidation of potassium permanganate to oxidize and decompose harmful gases in the air to achieve the purpose of purification. At the same time, it is for Formaldehyde, nitrogen oxides, hydrogen sulfide, and low-concentration aldehydes and organic acids have high removal efficiency. The potassium permanganate uses special activated alumina as the carrier, and is produced through high-temperature solution pressurization, decompression and other processes. It has more than twice the adsorption capacity of similar products, high strength and long life. In addition, the coconut shell activated carbon in this mixed filter material has a specific surface area of more than 1250㎡/g, an iodine adsorption value of more than 1100mg/g, an abrasion resistance of more than 95%, a gray value of less than 2.5%, and a moisture content of less than 8%.

Preferably, the ratio of the total mass of potassium permanganate alumina balls to the total mass of coconut shell activated carbon is 1:2. After testing, this ratio can be very effectively used in the car environment, that is, the coconut shell activated carbon physically adsorbs the target gas at the initial stage, and the unadsorbed part of the gas is removed by the chemical reaction of potassium permanganate alumina balls; After a period of time (determined by the specific use environment), the air in the car is improved. At this time, the coconut shell activated carbon begins to slowly release the gas adsorbed before, which is discharged after being treated with potassium permanganate alumina balls.

Preferably, the antibacterial layer 3 is made of antibacterial non-woven fabric with uniform thickness, which has good safety, spectrally efficient antibacterial properties and excellent washing resistance, and has been tested and clinically proven by many authoritative health units at home and abroad : The fabric finished by this product has obvious antibacterial, anti-inflammatory, deodorant, anti-mildew, anti-itch, astringent effects, and the antibacterial rate against common harmful bacteria is as high as 99%. And it is non-irritating to the human body, has no allergic reaction, is non-toxic, non-teratogenic, non-mutagenic, non-potentially carcinogenic, does not contain harmful substances such as formaldehyde and heavy metal ions, and meets environmental protection requirements. The antibacterial layer in this product is prepared from this antibacterial sanitation treatment agent according to the scientific proportion and strict and standardized process, which fully meets the technical standards.

Preferably, wrapping is added to the sides of the high-efficiency particulate filter layer 4 .

Preferably, the chemical purification layer 5 is made of modified columnar activated carbon. This layer is currently using alkali-modified columnar activated carbon, which is particularly effective for acid gases such as sulfur dioxide. In addition, the most important point is that this layer can also be changed according to different use environments. Different types of modified activated carbons increase the range of use and flexibility of use of the product.

Preferably, the inner wall of the filter body 11 is close to the melt-blown non-woven fabric made of PP material, wherein: coarse filter layer 2, antibacterial layer 3, high-efficiency particle filter layer 4, chemical purification layer 5 and high-efficiency selective adsorption layer The surfaces of 6 are tiled in turn and pressed against each other, while the side surfaces of the coarse-effect filter layer 2, the antibacterial layer 3, the high-efficiency particle filter layer 4, the chemical purification layer 5 and the high-efficiency selective adsorption layer 6, and the bottom surface of the high-efficiency selective adsorption layer 6 All are fastened on the melt-blown non-woven fabric by hot-melt adhesive bonding. Easy to install.

When the vehicle-mounted chemical filter of the present invention is working, the air to be treated is pushed by the fan, and then passes through the high-efficiency selective adsorption layer 6, the chemical purification layer 5, the high-efficiency particle filter layer 4, and the antibacterial layer 3, and finally the clean and healthy air passes through the coarse Efficient filter layer 2 is sent out.

In the vehicle-mounted chemical filter of the present invention, its coarse-effect filter layer 2, antibacterial layer 3, high-efficiency particle filter layer 4, chemical purification layer 5 and high-efficiency selective adsorption layer 6 are fixed in the filter net box body 1 successively, and this structure is simple, It can effectively remove fine particles such as PM2.5, inhibit the growth of bacteria in the car, improve the circulation speed of the air in the car, and protect human health. At the same time, the vehicle-mounted chemical filter of the present invention can also quickly, efficiently and stably absorb and treat the target gas, thereby improving its service life.
