Description

Round respiratory gas high-cleanness filter box

Technical Field

The invention relates to the technical field of respiratory gas filtration, which is to filter the inhaled and exhaled gas of a human body by a special filter box in a high-cleanness way, thereby solving the problems of personal respiratory system protection and social infectious disease prevention and treatment.

Background

People need to wear protective articles for protecting respiratory systems in air environments polluted by harmful substances such as bacteria, viruses and the like so as to prevent harmful substances from being inhaled to damage health and endanger life. The filtering function of the existing mask technology is melt-blown cloth filtering material, the filtering material is directly covered on the face for filtering, and the mask has a certain function, but the respiratory system cannot be well protected.

The commonly known breathing protection filtering technology is to make a melt-blown cloth for filtering into a mask, such as a medical mask, an N95 daily protection mask and the like, and has the defects that the filtering material covers the face and is influenced by the area, only the filtering material with the pore diameter of more than or equal to 0.3 micrometer can be used, bacteria with the particle diameter of more than or equal to 0.3 micrometer are relatively more definitely filtered, viruses with the particle diameter of 0.02-0.18 micrometer are not definitely filtered and can only be adsorbed by static electricity, on one hand, the static electricity adsorption can not realize high-cleanness filtering, viruses still escape and penetrate, on the other hand, after a large amount of fine particles and damp gas in filtered air are influenced by the static electricity, the static electricity quickly drops, and the later-stage filtering of the particles with the pore diameter smaller than the filtering material, such as the viruses and the like is not definitely finished. In particular, the fine particles in air are very large, even if the particles with the size of more than 0.3 micron are usually 30000-200000 PC/L, and the air environment is as high as 400000PC when the difference is poor. Therefore, the pure electrostatic filtration of the melt-blown fabric has large electrostatic consumption, and a lot of fine particles penetrate through the melt-blown fabric. The high-intensity environment pollution is simulated by the wolf smoke, and experiments show that 25 g of melt-blown cloth can be penetrated by the color dust when the medical mask is worn through two minutes, and 50 g of melt-blown cloth can be penetrated by the color dust when the N95 mask is worn through 5 minutes.

The prior known filter has large volume, is mainly used for indoor filtration and is not suitable for the personal equipment for human breathing. In particular, in the filter of the known art, the high sealing between the filtering material and the container is difficult to guarantee, and the risk of virus leakage is high.
