Description
Technical field
The utility model is related to air conditioning filter field, and more particularly to a kind of laying dust of centralized air ventilation system goes cleared
Change device and system.
Background technology
In the last few years, the construction industry of China was quickly grown, and centralized air ventilation system is because its air-treatment amount is big, use
It is convenient, widely used by Modern City Building the advantages of noise is low, comfort level is high, the public place of upper scale for example hotel, hospital,
Comprehensive market, track traffic etc. employ central air-conditioning system substantially.Centralized air ventilation system mainly has fan coil
Plus VMC and all-air system.Small space etc. mainly uses primary air fan-coil system, and large space is mainly using complete empty
Gas system.The air-conditioning system of centralization have air-flow it is gentle, without leakage hidden trouble, comfort level be high, the low advantage of noise, can provide
More comfortable environment.
The hygienic conditions of central air conditioning are also relevant with system design, management service except relevant with frequency of use.It is related real
Checking is bright, and air-conditioning laying dust and service life are into positive correlation.Air-conditioning system service life is longer, and the laying dust of accumulation is more in airduct.
The design of the internal sanitary situation and system of air-conditioning system airduct also has relation, the circular duct gauffer position of design of air conditioning
Put, rectangular air duct angle position be dust accumulation region occurred frequently.National health ministerial standard《Public place central air conditioning ventage
System cleaning and sterilizing specification》（WS/T396-2012）The centralized air ventilation system of middle regulation public place answers periodic cleaning with disappearing
Poison.Relevant investigation finds that many public places in Nan Chong units of operation are only limitted to part system or system to the clean range of central air conditioning
Section of tubing.On the cleaning way of air-conditioning system, due to not pre- when some air-conditioning duct design sizes are too small or design
Stay the cleaning inside access hole, airduct more difficult or can not clean, be only capable of simply entering pedestrian at air outlet, return air inlet
Work cleaning, wiping；The airduct laying dust of less cleaning is more and more, may result in and a large amount of pathogenic bacteria are grown in airduct, as one
The cradle of pollution, makes central air-conditioning system turn into propagation, the medium in diffusion pollution source.
Centralized air ventilation system pollutes very big to the health effect of people, is lived for a long time in this sordid environment
Work, people will feel headache, tired, and go out to lose face nose larynx irritation etc., causes communicable disease, anaphylactia and not
Good building syndrome etc..Sordid dust is alternatively arranged as virus, the carrier of bacterium, and pathogen is broadcast by central air-conditioning system
Public place is scattered to, so as to trigger the prevalence of respiratory infectious disease or break out.Correlative study shows central air-conditioning system in air
Important instrumentality is played in pathophorous propagation.
At present, the dust collection method and chlorination equipment that centralized air ventilation system is used mainly have：
1. pocket type or board-like strainer filtering technology, the full air type that this technology is widely used in large-scale public place are concentrated
Air conditioner ventilating system；The just screen pack such as effect, middle effect, efficient mainly is installed in air-conditioner wind cabinet-type air conditioner air inlet；This method is used simply,
Filter screen can be regularly replaced, cleaned；Weak point：Low efficient filter screen can only dedusting, it is impossible to sterilize, product of the long term accumulation on filter screen
Dirt easy breed bacteria under appropriate conditions, delivers to air conditioning area by air-conditioning system, causes secondary pollution.It is middle to imitate, efficiently
Screen pack aperture it is smaller, part bacterium can be filtered, but easily block, dust is cumulative to cause windage increasing, send
Air quantity reduces, energy consumption rise, operating cost increase.Do not possess a wide range of, quick sterilization effect during epidemic disease.
2. Ultraviolet Disinfection, this technology, which is mainly used in, is suitable for the places such as small space such as hospital；Uviol lamp skill
Art has stronger broad-spectrum bactericidal capacity, sterilization of high efficiency in the short time.Weak point：UV-device can only be degerming, it is impossible to
Dedusting, the ozone of generation can cause secondary pollution, be adapted to operate under conditions of nobody, there is significant limitation.Ultraviolet is worn
Saturating ability is weaker, can only carry out limited sterilization to air port regional area in centralized air ventilation system, it is impossible to moving air
And inner-walls of duct carries out disinfection.For designing the wind cabinet-type air conditioner of Wind Volume, ultraviolet is short due to irradiation time, it is impossible to fast
The air-flow that speed passes through effectively is sterilized；In addition, uviol lamp short life, changes frequent.
3. electrostatic precipitator carries out Electrostatic Absorption, this technology is applied to big-and-middle-sized all-air air conditioning system；Electrostatic is removed
Dirt utensil has windage small, and purification efficiency is high, the features such as efficiency of dust collection is high, but single electrostatic precipitation formula is sterilized in electrion
Produce O3Nitrogen oxides side effect is also produced simultaneously, it is difficult to meet practical application needs.
