Description
Technical field
The present invention relates to technical field of air purification, and in particular to a kind of heating pipe method for purifying indoor air.
Background technology
Heating and ventilating pipeline sends airduct, central air-conditioning ventilation duct, industrial supply and exhaust ventilation duct, environment friendly system back to as cleaning system
The common components of suction airduct, but current heating and ventilating pipeline does not possess good air-filtering ability.And with for many years to sky
The continuous accumulation of the various harmful substances of discharge, air quality has been subjected to serious pollution, particulate matter in air and various
The life security that toxic and harmful pollutant gives people brings serious threat.It is no matter indoor or outdoor, deposited in air
Biological pollutant (bacterium, virus, fungal spore, dust, dust mite), smell pollution thing, contaminants of chemical origin (second-hand-cigarette,
The hazardous air pollutants of formaldehyde, benzene homologues, factory and vehicle discharge), airborne suspended particle pollutant (PM2.5) etc..Institute
Interior is entered directly into the contaminated air by heating and ventilating pipeline, human body can be had undesirable effect.
The content of the invention
The technical problems to be solved by the invention are to improve a kind of construction simply, empty in the heating pipe of good purification
Gas purifying method.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of heating pipe method for purifying indoor air, specific method is as follows：
(1) air is blown into heating pipe using air blower, first air mistake is set in the inlet end of heating pipe
Filter screen, floater filtering larger in air is fallen；
(2) it is located at the rear portion of screen pack and twice metallic fiber sintered felt is set in heating pipe, air is by first
After filtering, then adsorption filtration is carried out by twice metallic fiber sintered felt, the particulate matter that can be crossed in air filtering, to PM2.5's
Filter efficiency is up to more than 95%；
(3) second screen pack, the part harmful in the air after being warmed are set at the gas outlet of heating pipe
Study the separate beginning actively, do not filtered out by preceding road, then natural sterilization sterilization is carried out to air by second filtering, to air
In the clearance of contaminants of chemical origin reach more than 98%；
(4) humidification process is carried out to interior using humidifier while heating, reduces indoor aridity, can improved
The breathing comfort level of people, while the effect of humidification can also effectively prevent the propagation of breathing problem.
First screen pack is common commercial air screen pack, can be fallen floater filtering larger in air
, prevent from entering space on inner pipeline plug plug metallic fiber sintered felt；
The surface of the second screen pack is provided with one layer of nano coating, by the catalytic action of nano coating, eliminates empty
All kinds of harmful components and peculiar smell in gas, and natural sterilization sterilization is carried out to air.
The nano coating contains by the component of following parts by weight：
The nano coating forming method is：Nano titanium oxide, modified RE and calcium activated are mixed in mixer,
Adhesive agent, Conductive graphite cream, nucleator and Tea Polyphenols are subsequently adding, 65-68 DEG C is warming up to, is thoroughly mixed, by second
Screen pack impregnates in the mixture, then dries.
Described nucleator is monocyclic carboxylate nucleator, specially benzoic acid sodium salt, benzoic acid aluminium salt, diphenyl acetic acid
The mixture of one or more in sodium salt or hexahydro-phthalic acid.By adding nucleator, good dispersion between material,
Compatibility is good, improves filtering adsorption effect.
The adhesive agent is regenerating and modifying waste oil, with stronger adsorption function, is had well to the particulate matter in air
Filtering adsorption effect.
Tea Polyphenols (TP) is the polyphenol compound of the separating-purifying from tealeaves particularly green tea, is the chief active of tealeaves
Composition, with extensive pharmacological action.Research has shown that Tea Polyphenols can suppress the GTF enzymes of bacterium, with calcium activated and nanometer titanium dioxide
Titanium is coordinated, and with catalysis, can play sterilized to air sterillization.
The modified RE is modified RE oxide, primarily serves catalytic action.
The processing method of the regenerating and modifying waste oil is as follows：
(1) using the waste oil produced in food and drink as raw material, vessel in heating to 70-90 DEG C of state is put into, keeps 30
Minute or so, part moisture evaporation is fallen, and the scum on surface is filtered off；
(2) in the waste oil input reactor in step (1), will open agitating function, mixing speed control 260~
280 revs/min, continuously stir 40 minutes or so, stop stirring, input atlapulgite is decolourized, atlapulgite and waste oil
Weight ratio be 2~6: 100；65-68 DEG C is maintained the temperature at, is continuously stirred 12 hours, carried out when temperature is down to 40 DEG C or so
Filtration treatment, collects liquid fat stand-by；
Used again after the semisolid atlapulgite recycling that above-mentioned filtering is produced；
(3) liquid fat is put into reactor, is warming up to 65-75 DEG C, put into formic acid, open stirring, continuously stir 30 points
Clock, then adds ethanol from the head tank of reactor, and unlatching is uniformly mixed；
The inventory of formic acid is the 3.5% of waste oil gross weight, the inventory of ethanol and the mol ratio of waste oil inventory
1.1:0.6；
(4) steam valve is opened, reactor is heated up, controlling reaction temperature is kept for 80 minutes at 80~120 DEG C,
It is then turned on reactor to be stirred, mixing speed is controlled at 260~280 revs/min, continuously stirs 60 minutes, terminating reaction；
(5) after reaction terminates, stratification is carried out to reactant, takes upper strata oil separator, by upper strata oil separator transfer
Into fractionation kettle, kettle temperature is risen, at 70 DEG C, normal pressure reclaims the complete ethanol of unreacted to control temperature；
(6) after ethanol is reclaimed and terminated, fractionation kettle is heated up to 90 DEG C or so, is incubated 6 hours, then stand 30 hours, divided and go
Lower floor's waste acid water, upper strata crude product is transferred in autoclave rectifying column, controls 120~150 DEG C of tower top temperature, vacuum pressure 1200
~1500Pa, reflux ratio 1：1 fractionation, obtains regenerating waste oil crude product；
(7) regeneration waste oil crude product is first neutralized with alkali lye, then is washed to neutrality, divided after removing water, oil reservoir carries out vapor
Distillation, remaining product is evaporated in vacuo, and removes low-boiling-point substance and water, then obtain final product regenerating and modifying waste oil through press filtration.
The beneficial effects of the invention are as follows：The inventive method is simple, it is easy to implement, and cost is relatively low, without any side effects, energy
Enough eliminate all kinds of harmful components and peculiar smell in air, and natural sterilization sterilization carried out to air, in air chemically
The clearance of pollutant reaches more than 98%.
