Description
Technical field
The present invention relates to a kind of gas fractionation unit, more particularly, to the separation that particle and gas are polluted in a kind of air
Purifier.
Background technology
Indoor air environment has with people most closely, most directly to be contacted.The IAQ of health is for guarantor
Quality of the life it is most important.According to statistics, modern society's most people in life about more than 80% time be indoors
Spend.So, influence of the indoor environment to health of people is particularly important.Many studies have shown that, overwhelming majority building is existed
Different degrees of room air pollution, and in some aspects, room air pollution is also more serious than outdoor air pollution, to people
Health threat it is bigger.
Room air pollution mainly includes physical pollution and chemical contamination.Physical pollution is mainly by suspended solid
Caused by particulate matter, including dust, pollen, overall suspended pellet (TSP), microbial cell, smog etc..Chemical contamination includes nothing
Machine gas and organic gaseous contamination, inorganic gas include S02、NOx、03、NH3Deng, organic gaseous contamination, to include volatility organic
Thing (VOCs), formaldehyde, benzene homologues etc..The closure of the interior space is become better and better in recent years, is hindered indoor and outdoor air convection current, is led
Indoor air pollutants are caused to be difficult to exclude, it is necessary to purify for indoor air pollutants.
Mainly there are physical absorption, filtering, electrostatic precipitation etc. for the purification techniques of indoor physical pollution；For chemical dirty
Dye
Purification techniques includes ozone oxidation, photocatalysis etc..It is single in order to realize filtering to air, sterilization, deodorization, refresh function
By a kind of technology, hardly possible has been realized.At present, the air purifier of simple function is withdrawn from the market already, existing air cleaning
Device, generally using the combination of a variety of purification techniques, using multi-filter system, for the physical pollution and chemistry in air
Pollution carries out comprehensive decontamination.
In the prior art, air purifier generally includes the particulate filter positioned at upstream and the photocatalysis positioned at downstream
Purifier, air enters after clarifier after particulate burning purifying device separation particle therein, then by the light catalytic purifying in downstream
Device carries out catalytic separation for contaminant gases.Smell photocatalysis purifier exists usually using molecular sieve filter element, gas pollutant
Wherein chemically reacted, so that decomposition gas pollutant.However, for pollution granule density very high air, it is passing through
After particulate filter, particulate filter may be passed through by remaining particulate pollutant；These remaining particulate pollutants can be assembled
In the catalyst surface of molecular sieve filter element, influence the catalytic action of catalyst, thus cause molecular sieve filter element can not realize for
The purification of gas pollutant；And the particulate pollutant of the deposition will also become the source of air purifier secondary pollution.
In order to solve to pollute influence of the too high air of granule density for molecular sieve filter element, CN201110228063.9's
Patent of invention proposes a kind of improved air separating purifying device, dust sensor is set before particulate filter, in air
Valve is set in clarifier, valve is opened when dust sensor detects high concentration dust, makes the sky of air inlet clarifier
Gas is flowed out by valve, and without molecular sieve filter element, thus avoid particulate pollutant remaining in high concentration dust for
The influence of catalyst in molecular sieve filter element.But, it is net without using photocatalysis in the technical scheme of the invention in high concentration dust
Change, can not just purify the dusty gas in air.
In order to solve the above problems, as CN201110228063.9 improvement, it is net that earlier application proposes a kind of air
Change device, when surrounding air middle particle concentration exceedes threshold value, the first independent air cleaning passage of formation and the second air cleaning
After air in passage, air is by electrostatic precipitator double purification, then light catalytic purifying carried out by catalyst filter core, from
And influence of the air high concentration dust for catalyst in molecular sieve filter element is avoided, while realizing for dusty gas in air
Purification.
But, in the structure of the air purifier of the technical scheme, as shown in figure 1, surrounding air middle particle concentration is less than
During threshold value, by the air of deduster when carrying out light catalytic purifying, air above flows downward after valve is reached
Light catalytic purifying is carried out to catalyst filter core, the air mass flow of purification is more than lower end required for causing catalyst filter core upper part
The air mass flow of purification required for part, and the reactant produced by reactant generator is uniformly produced, and may cause to urge
Agent filter core upper end can not handle the gas pollutant in air completely, and portion gas pollutant flows from catalyst filter core upper end
Go out；And after purifying for a long time, cause the purifying property of the top and bottom of catalyst filter core uneven.
