Indoor air purifying bag and preparation method thereof

Abstract

The invention relates to an indoor air purifying bag and a preparation method thereof and aims to solve a problem that an indoor air purifying bag in the prior art is complex in technology and is inconvenient to use. The indoor air purifying bag is prepared by filling a breathable hydrophilic fabric bag with active carbon granules and vermiculite granules, wherein the active carbon granules and the vermiculite granules are coated by air purifying catalyst materials in the same function, or the different functions, or incompletely same functions. The fabric is supported by a catalytic material which has a catalytic decomposition function on formaldehyde, ammonia and the like. The carbon granules are supported by a catalytic material which has a catalytic decomposition function on benzene-series substances and formaldehyde. The vermiculite granules are supported by a catalytic material which has a catalytic decomposition function on the majority of TVOC. The preparation method includes steps of preparing the catalytic materials and deionized water into a catalyst solution, enabling a thin-piece bag material of the breathable hydrophilic fabric bag, the active carbon granules and the vermiculite granules to be supported with the catalyst solution in a coating and impregnating manner, uniformly mixing the active carbon granules and the vermiculite granules supported with the catalyst solution, packaging the active carbon granules and the vermiculite granules in the fabric bag supported with the catalyst solution, and storing the fabric bag in a sealing manner. The indoor air purifying bag has effects of inhibiting bacteria, proofing mould, preventing insect, removing odor and harmful components in air, is simple in form, is convenient to use and is less in influent factor.

Description

technical field [0001] The invention relates to an air purification device, in particular to an indoor air purification bag and a preparation method thereof. Background technique [0002] People who live and work in comfortable buildings are often plagued by unexplained illnesses such as headaches, eye, nose and throat discomfort, dry cough, dry and itchy skin, dizziness and nausea, difficulty concentrating and sensitivity to odors, etc. etc., and these symptoms will disappear automatically once they leave the building, which is called "sick building syndrome" (SBS). The investigation found that the disease was caused by indoor air pollution. Indoor air pollution has become the behind-the-scenes influence on human health, and indoor air purification has also attracted people's attention. Indoor air pollution is mainly caused by harmful substances such as formaldehyde, benzene series (benzene, toluene, xylene, etc.), ammonia, TOVC (volatile organic compounds), inhalable par...

AI Technical Summary

Problems solved by technology

The principle is to directly spray or brush it on the man-made board for decoration, and formaldehyde will undergo a certain chemical reaction and be consumed to form another chemical substance (some products contain urea, which will react to form unstable urea-formaldehyde glue or just play a role). It must be closed); instead of degrading formaldehyde gas molecules to make it into a harmless substance, it can only be used before spraying paint on the artificial board, and it is difficult to control the amount. It has no effect on the harmful gas that is continuously emitted in the later period. Very easy to rebound

And the walls, floors, sofas and other places cannot be used. It is a simple emergency treatment method with limited scope of use, and cannot achieve the purpose of long-term removal of formaldehyde.

[0007] 2. Antivirus and deodorizing fragrance: It is a volatile chemical substance. It relies on its own fragrance to cover up the bad air characteristics, giving people an illusion that it cannot really remove harmful gases. Long-term use will also harm the human body. have some bad effects

[0008] 3. Activated carbon adsorption method: activated carbon made of wood, fruit shell, bamboo, coal, etc., can absorb suspended particles and macromolecular harmful gases in the air by using its porous physical characteristics, such as smoke, dust, benzene, etc. substances, odor molecules, etc., need to be replaced regularly, the actual use efficiency is not high, and it cannot achieve the purpose of eradicating harmful gases

Not suitable for use in domestic environment

[0010] 5. Electrostatic dust removal method: use the principle of opposite-sex attraction and same-sex repulsion of electrodes to absorb pollutants in the air, but there are problems of incomplete and incomplete adsorption, and the electrode plates must be cleaned regularly

However, it is very insufficient in the purification of formaldehyde, ammonia, benzene and other harmful gases brought by interior decoration.

At the same time, in addition to the high cost, its long-term power consumption and noise pollution are also issues to be considered

[0014] It can be seen that there are deficiencies in the current harmful gas purification technology and products, and there are many restrictions on the use in the home environment
