Effect, flue gas particle is adsorbed, and thoroughly, for fume purifying rate up to 98%, the flue gas of discharge is pollution-free, protects environment for purification.
Detailed description of the invention
Fig. 1 is the principle of the present invention block diagram；
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Kitchen fume purification treatment method embodiment 1 as shown in Figure 1, comprising the following steps:
(a), under the action of air-introduced machine, cooking fume mixed pollutants enter rectifying cavity, and rectifying cavity utilizes lipophilic filter
Material carries out absorption retention to large particles of oil mist, and part grease is separated；
(b), the flue gas for removing grease enters UV photodissociation device and carries out photodissociation purification, is irradiated using UV ultraviolet beam pungent
Flue gas cracks flue gas, makes pungent flue gas Degradation and Transformation at low molecular compound, water and carbon dioxide, while decomposing in air
Oxygen molecule generate ozone, in flue gas toxic substance and peculiar smell carry out decompose and taste removal；The UV photodissociation device includes UV light
Solve lamp, ion ozone generator and photocatalyst of titanium dioxide.
(c), flue gas is filtered to oil smoke and adsorbs oil gas particle by active carbon filter plate；Active carbon filter plate packet
Include porous substrate and the active carbon being coated on the porous substrate made of ceramics, natural synthetic fibers or sponge material.
(d), remaining flue gas enters electrostatic oil and smoke cleaner, and cooking fume is ionized and dissociated under the action of high voltage electric field,
The grease liquid come is finally decomposited by centralized recovery；The working voltage of electrostatic oil and smoke cleaner is 31~38KV, high-voltage electricity
Field plate width is not less than 140mm.Electrostatic oil and smoke cleaner uses RS barbed nail corona electrode.
(e), de-oiling flue gas flows into adsorption filter and purifies again, and adsorption filter is using all-glass paper absorption oil smoke
