Description
Technical field
The invention belongs to technology for cooking fume control field, particularly relate to a kind of domestic pyrolytic and purify
Lampblack absorber and the method for purifying oil fume.
Background technology
Lampblack absorber is to outdoor a kind of electrical equipment by the oil smoke discharge that produces in cooking process, now
It is widely used in each family.Compared with external cooking mode, Chinese tradition diet tends to
Use the production methods such as fried, grillING, quick-fried, it is easier to produce that quantity is more, concentration is higher
Oil smoke.Existing lampblack absorber generally by the captivation of the blower fan installed in lampblack absorber by oil
Cigarette is directly discharged to outdoor, and the part oil droplet in oil smoke can adsorb or be agglomerated in this process
On wind net, parts and the pipeline of lampblack absorber, add the flow resistance of oil smoke, cause blower fan to bear
Carrying and increase, lampblack absorber flue blocks, and operational efficiency reduces, affect lampblack absorber normally work and
Service life, and the most purified oil smoke is directly discharged in air, i.e. pollutes environment and endangers
Do harm to public health.
Prior art discloses the lampblack absorber much with purifying oil fume effect, as filter-type is clean
Change lampblack absorber, electrostatic purification range hood, photolysis type purification range hood, Water filtering type purification
Lampblack absorbers etc., although the most all to realize oil smoke clean for the purification range hood of the above-mentioned type
Change, reduce fume pollution, but appoint and so there is various problem and shortage: filter-type purification range hood
Utilize the Van der Waals force existed between body surface, adsorb with the suspended oil smoke particle in air stream dirty
Dye thing, its shortcoming increasing and increase with smoke particle thing that be filtration resistance, purification efficiency is therewith
Till being decreased until blocking；The electrostatic purification range hood static discharge by electrode, by storehouse
The effect of logical sequence power, separates smoke particle thing from air-flow, reaches to purify purpose, uses
Ratio is relatively hazardous, it is difficult to ensure that the flames of anger produces, and the decay of later purification effect is too fast, safeguard and
Use cost is higher, and fire incident happens occasionally, and maintenance clean produces secondary pollution；Photolysis
Type purification range hood is that the ozone and the cold burning of oil smoke utilizing special uviol lamp to produce is to purify oil
Cigarette, first uviol lamp relatively costly, current domestic UV fluorescent tube cannot meet minimum use
Require and import fluorescent tube is expensive, actual motion also is difficult to ensure device light tight, ultraviolet
Human body can be caused mortal injury by light and ozone leakage, uses and there is potential safety hazard, ozone simultaneously
The effect of decomposing oil smoke is unsatisfactory, bigger smoke particles more than 20 μm cannot be decomposed or
Person cannot thoroughly decompose, and is therefore only applicable to the oil smoke such as western-style food and Japanese and Korean cooking less food and drink kitchen
Room, also exists connate ability not enough to the purified treatment that the oil smoke amounts such as Chinese meal are bigger；Water filtering type
During the use of purification range hood, water is easy to go out air flue, causes oil smoke straight from air flue
Run in into air, exist and cannot purify or purify halfway situation, and secondary pollution is tighter
Weight.Therefore, people are badly in need of a kind of purification that can be quick, complete, safe and reliable, stable
The lampblack absorber of oil smoke.
Summary of the invention
In order to solve, the purification techniques of existing purification range hood existence is immature, it is dirty to be easily generated secondary
Dye, fire-fighting do not pass a test, operation and maintenance is with high costs and easily to skills such as human body damage
