Pipe fitting 150.
It is spread since filter will cause bacterium and be enriched in filter, it is provided with bacteriolyze enzyme layer 200 in the filter
(lysozyme is a kind of hydrolase for being acting exclusively on microorganism wall, claims packet muramidase or the hydrolysis of N acetyl murein glycan
Enzyme, it exclusively acts on β 1,4 keys in peptide polysaccharide molecule between N acetylmuramic acid and N acetylglucosamine, thus broken
The cell wall of bad bacterium is allowed to relaxation and loses the protective effect to cell, finally makes bacterolysis dead), and have changed
Adsorption layer of the original based on active carbon is adsorbed using the stronger material of adsorption capacity.Bacteriolyze enzyme layer 200 is located at the first floor, band
Encounter first of the filter that germy smog has arrived cigarette smoking system is exactly bacteriolyze enzyme layer 200, after so that bacterium is come in just
Activity is lost, filter is made not become a pollution sources again in the long-term use.
ULPA film layer 300 is provided with after bacteriolyze enzyme layer 200, the full name in English of ULPA film layer 300 is
UltraLowPenetrationAirFilter, Chinese are ultra high efficiency air filter or ultralow penetrance air filtration
Device reaches 99.999% or more to the filter efficiency of the dust particles such as 0.1-0.2 μm of particle, smog and microorganism.ULPA film
Layer 300 i.e. ultra high efficiency air filtration film layer or ultralow penetrance air filtration film layer, can not only adsorb a variety of particles, may be used also
To remove the peculiar smell in smoke removing, then poisonous and hazardous polar molecule in adsorbing smoke again purifies air with solid base,
Virion is killed, pollute the ingredient in smog will not to equipment inside.
Active carbon layer adsorbs polar molecule or nonpolar molecule.It is stupid such as NH3, formaldehyde.
Cold catalyst layer 500 mainly carries out oxidation reaction to inorganic harmful substance, generates harmless carbon dioxide and water.
Anion layer 600 can occur electrically to neutralize and settle absorption with the macromolecular in smog, while Electrostatic Absorption arrives
Flue dust, bacterium, virus surface settle it and make bacteria inactivation.
Operation cigarette smoking system filter provided in this embodiment comprising have filter housing 100 and filter layer, filter
Device shell 100 is internally provided with chamber, and for installing filter layer, and the lid on filter housing can be opened, and is convenient on demand more
Filter layer is changed, cost is greatly reduced.Air inlet 111 and exhaust outlet 131, air inlet 111 are provided on filter housing 100
With 131 connecting chamber of exhaust outlet, gas flow channel is formd between air inlet 111 and exhaust outlet 131.Filter layer includes successively
Bacteriolyze enzyme layer 200, ULPA film layer 300, active carbon layer 400, cold catalyst layer 500 and the anion layer 600 of setting, filter layer peace
In flow channel, bacteriolyze enzyme layer 200 is arranged close to 111 one end of air inlet, and anion layer 600 is close to 131 one end of exhaust outlet
Setting.Filter layer obstructs in gas flow channel, and the gas entered from air inlet 111 passes sequentially through bacteriolyze enzyme layer 200, ULPA
Then film layer 300, active carbon layer 400, cold catalyst layer 500 and anion layer 600 are discharged from exhaust outlet 131.Surgical procedure
In, smog enters from air inlet 111, is absorbed by the harmful substance in smog when filter layer, and smog is after purification from row
Port 131 is discharged, good purification, during the gas of discharge is not easy to influence operating room environment, and smog passes through filter layer,
Harmful substance in smog passes through multiple filtration, and contact of the harmful substance with filter layer in smog is abundant, and the clarification time is long, has
Evil substance can be not easy remaining bacteria in filter by quick inactivating, be not easy to become pollution sources.
