Problems solved by technology

Although the currently commercially available air purification devices have a certain effect of filtering out dust, bacteria and viruses, there is no description of components that can completely filter viruses
In addition, because the filter medium materials used are generally not resistant to high temperatures, there has been no use of high temperature heating to kill the virus on the filter medium materials; there is no report of additional chemical disin

Embodiment 1

[0020] In this embodiment, a porous ceramic membrane is used to filter a high-temperature air purifier for killing pathogenic microorganisms, as attached figure 2 As shown, the porous ceramic filter membrane 4 is a porous alumina ceramic membrane tube 41 with a pore size of 3-5 μm or a pore size of 0.7-1 μm or a pore size of 0.2-0.5 μm, and the disinfection element 5 is a high-temperature heating device, and the high-temperature heating device consists of An electric furnace wire 8 with a temperature control system 9 is wound on the outer wall surface of the porous alumina ceramic membrane tube 7 .

[0021] The air purifier described in this embodiment draws the dirty air containing pathogenic microorganisms from the inlet 2 into the air storage collection area 3 by the fan 1 installed at the outlet 6 of the air purifier 3, and passes through the porous alumina ceramics arranged on the air passage. The membrane tube 41 is filtered, and the purified air is discharged from the ...

Embodiment 2

[0026] like image 3 Shown, in the air purification device of present example porous ceramic membrane filter killing pathogenic microorganisms, porous ceramic filter membrane 4 is the corrugated plate porous ceramic filter membrane 42 that has convex part 11 and concave part 12, two corrugated plate porous ceramic filter membranes 42 Ceramic filter membrane 42 forms one group of filter unit; Disinfection element 5 is ultraviolet lamp tube 10, and ultraviolet lamp tube 10 is installed between two corrugated plate shape porous ceramic filter membranes 42 of each group of filter unit; In this group of filter unit, The convex parts 11 of the two corrugated plate-shaped porous ceramic filter membranes 42 are arranged oppositely, and the concave parts 12 are arranged oppositely.

[0027] The present embodiment adopts the corrugated plate shape porous ceramic filter membrane 42 for the porous ceramic filter membrane 4, and the porous ceramic filter membrane air purifier that the disi...

Embodiment 3

[0029] like Figure 4 , in the air purification device for filtering and killing pathogenic microorganisms by porous ceramic membrane, the porous ceramic filter membrane 4 is a plurality of flat porous ceramic filter membranes 43 arranged in parallel, and the disinfection element 5 is a chemical disinfection device. The disinfectant tank 17 of the liquid 16, the infusion pump 15 and the atomizing nozzle 18 connected with the infusion pump 15, the atomizing nozzle 18 is located above the interlayer 14 between two flat porous ceramic filter membranes 43.

[0030] Present embodiment adopts the air purification device of chemical disinfection for disinfection element 5, see appendix Figure 4As shown, under the action of the slight negative pressure caused by the fan 1, the indoor air is sucked into the air storage collection area 3 from the inlet 2, and the purified air passes through the flat porous ceramic filter membrane 43 arranged on the dirty air channel, and the purified a...

Abstract

The invention discloses an air purification device capable of filtering and killing pathogenic microorganisms by use of a porous ceramic membrane. The air purification device comprises an air accommodating and collecting region, wherein the air accommodating and collecting region is provided with a vitiated air inlet and a clean air outlet; the part, which is adjacent to the clean air outlet, in the air accommodating and collecting region is provided with the porous ceramic filtering membrane; the air accommodating and collecting region is internally provided with a disinfection component, and the clean air outlet is provided with a blower. The inorganic ceramic membrane adopted by the air purification device has the characteristics of high temperature resistance, corrosion resistance and ageing resistance, so that the air purification device is long in service life, especially has higher separation precision and separation efficiency than those of a traditional purifier, and can effectively ensure that the pathogenic microorganisms are completely intercepted and are completely killed in equipment by use of high temperature, ultraviolet light or a chemical disinfection solution so as to prevent virus from spreading, polluting and infecting towards the environment by virtue of exhausted air. The air purification device is simple in equipment structure, high in stability, reproducible in core component, convenient to use and thorough in pathogenic microorganism killing effect.

Description

technical field [0001] The invention belongs to the technical field of air filtration, purification and killing of pathogenic microorganisms, and relates to an air purification device which adopts a high-temperature-resistant porous filter medium to retain pathogenic microorganisms, and then kills pathogenic microorganisms by high temperature, ultraviolet light or chemical disinfectant. Background technique [0002] Infectious atypical pneumonia (hereinafter referred to as "SARS" or "SARS") is a respiratory infectious disease, and the current situation shows that air is its main medium of transmission. One of the keys to fighting SARS is to avoid further infecting others. In particular, areas such as "SARS" wards, "suspected" wards or "fever clinics" have extremely high virus concentrations in the air. Healthy people in these areas, especially medical staff, are most likely to be infected. On the other hand, patients themselves may also continue to be infected. Studies hav...
