Embodiment 1

[0021] The equipment containing metal organic framework adsorption material provided by the present invention is applied on the gas mask, such as Figure 1-2 As shown, it includes a gas mask main body 1 that is placed on the mouth and nose of the human body and whose edges perfectly match and fit the user's face. The main body of the gas mask 1 is respectively provided with one or two drug filtering devices 2 corresponding to the front or both sides of the human nose. The drug filtering devices 2 contain metal organic framework materials 21 wrapped in non-woven fabric layers, and The air inlet 22 is at the upper edge. During the use of the gas mask, the main body of the gas mask 1 fits the user's face perfectly, and the poison filtering device 2 is arranged in front of or on both sides of the nose of the human body. The metal-organic framework adsorption material 21 wrapped in non-woven fabric in the device 2 is adsorbed and filtered, and the air inlet 22 of the poison filter...

Embodiment 2

[0030] The equipment containing metal organic framework adsorption material provided by the present invention is applied on the gas mask, such as Figure 1-2 As shown, it includes a gas mask main body 1 that is placed on the mouth and nose of the human body and whose edges perfectly match and fit the user's face. The main body of the gas mask 1 is respectively provided with one or two drug filtering devices 2 corresponding to the front or both sides of the human nose. The drug filtering devices 2 contain metal organic framework materials 21 wrapped in non-woven fabric layers, and The air inlet 22 is at the upper edge. During the use of the gas mask, the main body of the gas mask 1 fits the user's face perfectly, and the poison filtering device 2 is arranged in front of or on both sides of the nose of the human body. The metal-organic framework adsorption material 21 wrapped in non-woven fabric in the device 2 is adsorbed and filtered, and the air inlet 22 of the poison filter...

Embodiment 3

[0039] According to the conditions described in claim 1, only the adsorption material is amorphous metal-organic framework material HKUST-1 particles with a particle diameter of about 1.2 mm wrapped in non-woven fabric, and the filling amount can be adjusted according to the size of the poison filtering device.

[0040] Compared with activated carbon, the filter material of traditional gas masks, the metal organic framework material has a huge specific surface area, and the pore surface can be modified with functional groups, and has higher adsorption capacity and wider adsorption range for toxic gases. The material's poison filtering equipment has a better adsorption effect on toxic gases and can better protect human health.

Abstract

The invention relates to toxicant filtering equipment containing a MOFs adsorption material. The toxicant filtering equipment is mainly used for solving the problem in the prior art that the adsorption capacity and adsorption range are relatively poor. According to the toxicant filtering equipment containing the MOFs adsorption material, through adopting the technical scheme that the toxicant filtering equipment containing the MOFs adsorption material comprises a gas inlet, a toxicant filtering equipment shell, the adsorption material and a protective equipment interface, wherein the gas inletis located at the upside edge of the toxicant filtering equipment shell, the adsorption material is filled in the toxicant filtering equipment shell and comprises a non-woven fabric, a metal-organicframework material layer or metal-organic framework material granules, the metal-organic framework material layer is made from multiple layers of non-woven fabric layers with a certain loaded amount of metal-organic framework material, the metal-organic framework material granules are granules with certain sizes and shapes granulated from the metal-organic framework material, and the metal-organicframework material layer or the metal-organic framework material granules are filled in the non-woven fabric, the above problem is better solved, and the toxicant filtering equipment can be applied to smoke helmets.

Description

technical field [0001] The invention relates to a poison filtering device containing MOFs adsorbent. Background technique [0002] In the chemical industry, emergency places for dangerous goods leakage, and in the process of people's production, use, storage and transportation of chemicals, toxic gases will inevitably be diffused into the environment. If it enters the human body through the respiratory system, it will cause poisoning and even life-threatening. The gas mask protective equipment can filter the toxic gas in the environment to a certain extent, reduce or avoid the harm of toxic chemicals to the human body. [0003] The adsorption material is the key to whether the gas mask of protective equipment can effectively filter toxic gases. At present, the adsorption filter material in the gas mask of protective equipment commonly used is activated carbon. Because activated carbon has a well-developed pore structure, it can fully contact with toxic and harmful gases in...
