Description
Technical field:
The utility model belongs to technical field of air sterilization and purification, is specifically related to the air disinfection and purification central air conditioning.
Background technology:
Along with the development of society, the progress of science and technology, the people's living standard improves constantly, make various types of central air-conditioning enter public places such as hospital, toilet, office building, market, hotel, cinema, airport, subway and underground structure fast, utilize central air-conditioning to regulate temperature, humidity and cleanliness factor, created a comfortable indoor environment to people.Various building mostly adopt enclosed type, the pollutants such as pernicious gas, virus, bacterium and aerosol that indoor electric appliance equipment, ornament materials and personnel activity produce make many people eyes, throat irritation, nasal obstruction, headache, dizziness, symptom---Cure of Sick Building Syndrome (being called for short SBS) such as uncomfortable in chest, drowsiness occur.Particularly l several years ago, SARS, bird flu, the outburst of the H1N1virus of present stage, the up-to-date epidemic situation communique that the World Health Organization delivers claims: global first influenza death toll surpasses ten thousand people, and wherein the U.S. has accounted for big portion.The improvement of indoor environmental pollution more and more causes people's attention, has caused the concern and the attention of domestic environment specialist and government.
Airborne virus and bacterium microbe exist with the aerosol form of discrete particles shape mostly, and people streams in public places is big, and dust particle is many more, and the content of its microorganism is also just high more.The dust particle number is proportional relevant with air-borne bacteria concentration in the air.Show that according to the U.S. CDC investigation bacterial concentration in the air in the floating material is at 700～1800cfu/m
3The danger that happens occasionally and infect.Infectious pathogen is attached in the air usually≤and 5 μ m swim on the particulate, flow with air by aerosol form and spread, and infected person is caused a disease because of sucking this air, causes cross-infection.The use of central air-conditioning increases the cross-infection incidence.
For this reason, the professional person studies improvement to the sterilizing and purifying facility of central air-conditioning, and technical scheme is nothing more than air disinfecting and purifying devices such as ultraviolet line style, ozone type, electrostatic, plasma-type.
The electrostatic air disinfecting and purifying device utilizes the high-pressure electrostatic principle of opposite sex attraction, the bacterium in the absorption dust.The electrostatic air cleaning unit---utilize anode discharge, make airborne particle positively charged, under the effect of Coulomb force, the particle of positively charged is captured on the electronegative dust collect plant.It is made of parts such as ionization apparatus, dust collect plant, air-supply arrangement and high voltage sourcies, can catch the above particulate of Φ 0.01 μ m, and windage is little, and efficiency of dust collection is up to more than 90%.It is low that shortcoming is to decompose airborne harmful bacteria, virus and organic pollution ability; Bacterium, virus are trapped on the electronegative dust collect plant with particle, and the dust particle on battery lead plate accumulates more and untimely cleaning, and the anxiety of secondary pollution is arranged.
Ozone type air disinfecting and purifying device (market claims the high energy electron type):
It utilizes high-frequency electric field to be added on two electrodes that medium isolates and does creeping discharge, at a large amount of plus or minus electronics of dielectric surface savings, has an effect with airborne molecule; Also useful corona discharge method produces ozone and other material.Produce the cluster ion of high-energy, high concentration during the work of energetic ion conversion zone, wherein cation can penetrate bacteria cell wall, gos deep into cell membrane inside, destroys the electrolytical balance of cell, damages cell membrane, causes the rapid death of bacterium, virus.The oxonium ion group who produces during the work of energetic ion reactor has extremely strong oxidation activity, makes large biological molecule such as DNA, the fracture of ANA chain, with the protein molecular structural deterioration, thus killing microorganisms; Its TVOC that can also degrade eliminates peculiar smell, and it effectively avoids dirt residual, non-secondary pollution.
Shortcoming: ozone is a kind of strong oxidizer, should not place inflammable, that explosion hazard gases directly contacts arranged; A little less than the penetration power of ozone, low to object vertical-depth killing bacteria ability, can not control of dust.Shortcoming is an ozone in case leak, and the human respiratory tract is damaged, and is eliminated gradually by hospital operating room, ward.

3Reach the Ministry of Public Health in the room about the II of hospital class environmental standard, energy consumption ultraviolet, that ozone will reach same Disinfection Effect is similar, is 160--240W; The particularly existence of above-mentioned defective, this also is the reason that present hospital seldom adopts.
The sterilizing and purifying effect of plasma-type air disinfecting and purifying device is remarkable, in any case than above-mentioned several classes from microorganisms such as kill bacteria, viruses; Degradation of organic substances and this three aspect of particle of catching more than the Φ 0.01 μ m are not inferior.
Several years ago the paper of this respect, patent are many, but nearly four, five years are replaced by the electrostatic air cleaning air-conditioning of zigzag sparking electrode on the market gradually.Analyze according to investigations, main cause is that the wire of the discharge positive electrode in the plasma-type air disinfecting and purifying device is disconnected easily, and the ozone that makes the zigzag sparking electrode into is too dense, and efficient is low.
