Description
Technical field
The present invention relates to toilet air purification field, be specifically related to a kind of bathroom induced draft fan with purification function.
Background technique
Toilet in family life, toilet is indispensable, and it is the place that people drain stool and urine and clean bathing.The two just addle of excrement, washing, the chemical product of cleaning-sterilizing, the gaseous combustions of water heater of people, add more airtight environment, larger humidity, less space etc., often make the air of toilet more easily dirty and pollution sources becoming in family.The peculiar smell of toilet is formed jointly by various material and factor, the mixing harmful gas come out in the ammonia wherein containing higher concentration, hydrogen sulfide, methane, carbon dioxide and various chemical product.
Ammonia is the major pollutants in toilet air, has strong impulse smell.In living environment, ammonia is mainly derived from biological waste, as human and animal excreta, urine, domestic sewage etc.Ammonia has very strong excitant, can cause stimulation, can occur bronchospasm and pulmonary emphysema time serious to skin, respiratory tract and eyes.Be subject to too much ammonia for a long time to pollute, people can be made to occur the symptoms such as uncomfortable in chest, pharyngalgia, headache, dizziness, apocleisis, fatigue, taste and smell go down.
Hydrogen sulfide is a kind of gas having rotten-egg odour, has severe toxicity, is mainly derived from irrigation canals and ditches, sewerage, rubbish thing, septic tank, salted vegetables pond, cesspool etc.High-concentration hydrogen sulfide can cause serious acute poisoning, occurs respiratory paralysis, to suffocate and in heart failure and dead.If the hydrogen sulfide of low density sucks for a long time repeatedly, can chronic toxicity be there is, show weakness, headache, the neurasthenia symptom such as dizzy, irritated.
The environment of toilet is airtight, high humidity, space are little, also for the harmful organisms such as malignant bacteria, mould, acarid create good condition of growing, causes producing a large amount of indoor etiology and anaphylactogen, toilet is become the most easily allow the place of ill.The medical expert abroad had even thinks, toilet the most easily allows the cancered place of people.
To the process of toilet gas in prior art, majority passes through ventilating fan, the air of toilet is discharged to the outside environment (being generally atmosphere environment), the clean gas of outside is sent into toilet, thus realize the displacement of toilet air, reach the object removing toilet air peculiar smell.
Typical bathroom exhaust fan, as CN202149070U discloses a kind of ventilating fan, comprise shell, motor, air sucking mouth and exhaust outlet, it also comprises casing and through-flow type wind wheel, the upper end of described casing is connected with described exhaust outlet, the lower end of described casing is located in described air sucking mouth, described through-flow type wind wheel is located at the described air sucking mouth place on described casing, described through-flow type wind wheel is connected with described motor, it is outside that described shell is located at described casing, described shell corresponds to described air sucking mouth place and be provided with air draught fenestra.
Existing bathroom exhaust fan, majority is by the air displacement of toilet to air, does not process described gas.Live because mostly current domestic Habitation form is that high density house is assembled, be discharged to outside gas meeting concentrated contaminated water outside atmosphere, everybody healthy can be affected equally.
Summary of the invention
The object of the invention is to propose a kind of bathroom induced draft fan with purification function, it utilizes built-in catalyst layer, carries out catalysis to the gas of toilet, by the harmful gas such as ammonia, hydrogen sulfide catalytic oxidation, become follow-up more disposable oxide, thus remove stink/peculiar smell.
For reaching this object, the present invention by the following technical solutions:
A kind of bathroom induced draft fan with purification function, comprise housing, filter layer, air purification layer and blower fan, the side of described housing is provided with panel, panel is provided with intake grill, and opposite side is provided with exhaust outlet, and intake grill is provided with grill cover, ultra-fine fibre glass filter layer is provided with between intake grill and blower fan, between exhaust outlet and blower fan, be provided with catalytic layer and adsorption layer, it is characterized in that
Described catalytic layer consists of:
A) 0.3%-10% is doped with the V of Sb
2o
5/ (MoO
3)
x(WO
3)
1-xwith TiO
2mixture, Sb:V
2o
5/ (MoO
3)
x(WO

1-x: TiO
2mol ratio be 0.25:1:2, described x is 0.1-0.5;
B) silver of 0.3%-8% and palladium mixture, the mol ratio of Ag and Pb is 2:5;
C) ZSM-5 molecular sieve of surplus;
Described adsorption layer is the activated carbon adsorption layer that load has Ag.
Induced draft fan of the present invention is when starting working, fan drives air to enter intake grill, the particulate matter be mingled with in air, floccule etc. filter in ultra-fine fibre glass filter layer, due to the existence of ultra-fine fibre glass, its particle diameter filtered is very little, and the particle comprising PM2.5 all can be filtered, simultaneously, described filter layer can not the very large resistance of bad student, does not affect the flowing of air.
Filtered air, enters catalyst layer.In catalytic layer, under the effect of catalyzer, there is catalytic oxidation, be oxidized to nitrogen oxide and oxysulfide in the ammonia in air, hydrogen sulfide etc., its peculiar smell disappears, and is also easy to subsequent treatment.Through adsorption layer, the microorganism in air, under the effect of activated carbon supported silver, is killed.Meanwhile, active carbon can absorbed portion pollutant.Air through purification enters air.
Induced draft fan of the present invention forms filter layer by choosing ultra-fine fibre glass, can filter the molecule (comprising haze PM2.5 particle) removed in air; By choosing specific components A and B component, under the effect of ZSM-5 molecular sieve, this catalyzer is made to produce synergistic effect, it at room temperature can play catalysis, ammonia in toilet air, hydrogen sulfide etc. are oxidized to oxide, and then with active carbon adsorption, various pollutant is reduced to ppm level; The silver of load in active carbon, effectively can kill the microorganism in air, thus effectively purify air.
