Embodiment 1

[0028] Embodiment 1, the air filter, the net cover and the front cover form the air outlet; the rear cover with the back cover forms the air inlet, and the middle air duct is provided with a fan driven by a motor. There is an air filter membrane in the air duct between the air inlet and the air outlet. The filter membrane is bag-shaped and made of carbon fiber. The bag is filled with air filter materials to neutralize the chemicals in the air. polluting substances. Due to the double-layer structure, it has a large enough fiber surface area and can perform double-layer filtration of air. After using for a period of time, the air filter membrane is full of pollutants. The entire filter membrane can be removed and discarded or disposed of, replaced with a new filter membrane, and continue to start the filter. After changing the filter membrane several times, the pollutants in the air can be completely removed. The air filter material in the bag is:

[0029] by weight FeSO 4 ...

Embodiment 2

[0030] Embodiment 2: roughly the same as Embodiment 1, the difference is that the air filter material is produced and sold separately as a product. Its composition is: by weight FeSO 4 4.5%, FeCl 2 1.3%, L-ascorbic acid 0.22%, the rest is water preparation component A 1000ml; by weight ZnCl 2 3%, FeCl 2 3%, CaCl 2 2.5%, AlCl 3 2%, MgCl 2 1.3%, KCl 0.6%, and the rest is water to prepare component B 1000ml. The carrier is diatomaceous earth.

Embodiment 3

[0031] Embodiment 3: roughly the same as Embodiment 1, the difference is that the composition of the air filter material is: by weight, FeSO 4 4%, FeCl 2 1%, L-ascorbic acid 0.2%, and the rest is water to prepare component A 1000ml; by weight ZnCl 2 2.5%, FeCl 2 2.5%, CaCl 2 2%, AlCl 3 1.5%, MgCl 2 1%, KCl 0.5%, the rest is water to prepare component B 1000ml.

Abstract

The invention is an air filter, which arranges a wind inlet and a outlet, there arranges a fan driven by motor in the wind channel between the inlet and the outlet, an air filter film with thickness thicker than 1mm in the wind channel, the structure of the film is bag type or box type, in which the carrier containing air filter compound is filled. The composition of the compound is: equal quantity of component A and component B and proper quantity of carrier, A is made up of FeSO4, FeCl2, L-ascorbic acid, and water; the component B is made up of ZnCl2, FeCl2, CaCl2, AlCl3, MgCl2, KCL and water. The confected A and component B are absorbed onto the carrier respectively when in use, it can be used after being dried.

Description

technical field [0001] The invention relates to a device for filtering, adsorbing and cleaning indoor air, an air cleaning composition used in the air filter, and a preparation method of the composition. Background technique [0002] At present, the phenomenon of air pollution is becoming more and more serious, especially with the use of various new decoration and decoration materials, and the use of building additives, the problem of indoor air pollution is very prominent. It has been reported that 3 million children fall ill every year due to indoor air pollution, and there have been incidents of death caused by indoor air pollution. Newly decorated houses must be ventilated for a certain period of time before they can be inhabited, but opening doors and windows for a long time to ventilate uninhabited houses will lead to many problems such as how to prevent wind and rain, how to ensure public security, etc.; Pollutants have become a problem for many newly renovated homes...
