Description
Technical field
The present invention relates to a kind of air purification field, in particular to a kind of air cleaning system and air purification method.
Background technique
Currently, indoor environmental quality is closely bound up with human health, it is chronically in undesirable indoor environment and be easy to cause
In the state of room personnel's inferior health, in some instances it may even be possible to cause disease.Indoor major pollutants include formaldehyde, PM2.5 particulate matter, bacterium
With microorganism etc..
Currently, indoor air quality improves using air cleaning system in more and more families.Commercial air purification system
System is mostly console mode, usually purifies single room, purification is limited in scope.
The main particulate matter by way of filtering of common clarifier, mostly uses high efficiency particulate air filter.Although this kind of sky
Gas purification system has good filter effect, but high efficiency particulate air filter resistance is larger, and power consumption when reaching nominal air delivery is higher.
In addition, high efficiency particulate air filter cannot kill bacterium, microorganism, filter replacement bacterium easy to breed instead not in time is caused secondary
Pollution.Therefore, consider for health and filter core shelf-life, just need replacing filter core every the set time, increasing makes
Use cost.
High efficiency particulate air filter PARA FORMALDEHYDE PRILLS(91,95) is without catharsis, therefore clarifier manufacturer provides the first based on active carbon filtering layer
Aldehyde purification.Active carbon is a kind of non-polar adsorbent, has superior absorption property to larger molecular organics, and formaldehyde is
A kind of polar molecule, active carbon are relatively poor to its absorption property.And active carbon the phenomenon that there are adsorption saturations, although it is available plus
The regeneration such as thermal method, but 800 DEG C or more of temperature is needed, and regeneration all has loss every time, and adsorption capacity is gradually reduced.
In addition to outstanding problems such as particulate matter, formaldehyde, interior is also usually present the phenomenon of fresh air volume deficiency.On the one hand, outdoor
Air quality is poor (especially winter), and people is made passively to form the habit not opened a window；On the other hand, the building gas built in recent years
Close property is preferable, and infiltration wind is reduced.These two aspects causes indoor fresh air amount deficiency jointly, and gas concentration lwevel is exceeded.
Summary of the invention
The present invention is to solve technical problem present in well-known technique and to provide a kind of environmentally friendly, efficient, energy-efficient air net
Change system and air purification method.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that a kind of air cleaning system
System, including shell, the shell are equipped with the air inlet of input outdoor air, the return air inlet of resorption room air and to indoor defeated
The air outlet of air out；It is sequentially with physical cleaning air element, biochemical purification air element from front to back in the shell
And blower；The input port of the blower is located at the rear side of the biochemical purification air element, the delivery outlet of the blower and institute
State air outlet connection；The air inlet and the return air inlet are respectively positioned on the front side of the physical cleaning air element.
Further, control unit and the monitoring list for detecting indoor and outdoor air pollutant are additionally provided on the shell
Member, the monitoring unit output signal to described control unit, and described control unit outputs signal to the physical cleaning respectively
Air element and blower.
Further, the air inlet is equipped with air inlet valve, and the return air inlet is equipped with return air valve, described control unit point
The air inlet valve and the return air valve are not outputed signal to.
Further, the monitoring unit includes formaldehyde sensor, carbon dioxide sensor, PM2.5 particulate matter sensors
And/or microbiological sensor.
Further, the physical cleaning air element includes primary efficient filter screen, the field electricity mould of sequence setting from front to back
Block and micro- electrostatic module.
Further, the biochemical purification air element includes the biochemical filtration net made of chitin fiber.
Further, biochemical filtration net cross section is waveform or zigzag.
The present invention also provides a kind of air purification method using above-mentioned air cleaning system, this method uses physics and life
Change compound air purification method, removes Particulate Pollution object with physical cleaning air element, and kill and be attached on particulate matter
Microorganism；Formaldehyde is removed with biochemical purification air element, and is suppressed growth of microorganism.
Further, this method comprises the following steps:
Room air standard parameter and outdoor air standard parameter is arranged in step 1 in control unit；
Step 2, it is dense that monitoring unit detects concentration of formaldehyde, gas concentration lwevel, PM2.5 particulate matter in indoor and outdoor air
Degree and microorganism concn, and will test signal and export to control unit；
Step 3, control unit will test signal and handled, and corresponding and room air standard parameter and outdoor air
Standard parameter is compared；
Step 4, control unit control the start and stop of physical cleaning air element according to comparison result.
Further, in the step 4, comparison result is grouped, every group of comparison result corresponds to different air cleaning works
Operation mode, air cleaning operating mode include at least following four:
Mode one, indoor accelerated test or microorganism concn > room air standard parameter, the room outdoor air PM2.5 concentration >
When outer air standard parameter, physical cleaning air element is opened, and air inlet valve is closed；
Mode two, indoor accelerated test or microorganism concn > room air standard parameter, the room outdoor air PM2.5 concentration <
When outer air standard parameter: physical cleaning air element is closed, and enters the wind valve opening；
Mode three, indoor carbon dioxide concentration > room air standard parameter, outdoor particle concentration < outdoor air mark
When quasi- parameter；Physical cleaning air element is closed, and valve opening is entered the wind；
Mode four, indoor accelerated test concentration, microorganism concn and gas concentration lwevel≤room air standard parameter, formaldehyde
Concentration > room air standard parameter, physical cleaning air element are closed, and air inlet valve is closed.
The advantages and positive effects of the present invention are:
1, purification function is more, while having physical cleaning air element and biochemical purification air element, physical cleaning air
Physics dedusting method removal Particulate Pollution object can be used in unit, kills the bacterium and microorganism being attached on particulate matter；It is biochemical
Air element is purified using pollutants such as biochemistry purification method removal formaldehyde, and the microorganisms such as bacterium is inhibited to grow.
2, the modules such as primary efficient filter screen, field electricity module and micro- electrostatic module can be used in physical cleaning air element.Just effect
Filter screen can retain large-sized particulate matter, avoid it from blocking micro- electrostatic module and protect chitosan clean unit；The electric module in field
Higher voltage charges the particulate matter in gas stream of pollution.Micro- electrostatic module is the microcavity matrix made of dielectric substance, can
Form microcavity matrix high field electricity, particulate matter of the capture with charge, and kill bacterium attached to it, microorganism etc.；Field electricity
