Zero discharge cooking fume purifier
Technical field
The present invention relates to a kind of air cleaning unit, be specially a kind of fume purifier of fume.
Background technology
Air quality more and more comes into one's own now, and the dust index becomes the important indicator of estimating air quality in the air.
Factory's flue dust, cooking fume are the important sources of dust in the air, are the oil smoke compositions and major part is arranged in these dust.Eliminating the oil smoke composition in factory's flue dust, the cooking fume, is to reduce air-polluting
Important measures.
Oil smoke can cause fume pipeline to block in addition, even causes fume pipeline to catch fire, and has potential potential safety hazard.
The device of effective elimination oil smoke composition not being set in the existing equipment and having the device design of eliminating the oil smoke composition now unreasonable is the key factor that causes air pollution, fume pipeline to block even catch fire.
The existing device of eliminating the oil smoke composition adopts sponge screen pack or papery screen pack, and at first the screen pack of these materials can not be high temperature resistant, moreover the filtering holes of these screen packs is too little, is blocked by greasy dirt easily, causes exhaust not smooth.
Screen pack needs regularly to clean, the existing device of eliminating the oil smoke composition when the cleaning and filtering net or screen pack when damaging, the device cisco unity malfunction, influence is normally used.
These eliminate the device of oil smoke compositions in addition, just simply solid in the oil smoke and liquid component are filtered out, the gas componant and the bacterium that can not filtering pollute, and this also is that the oil smoke of discharge causes the bad reason of smell on every side.
The existing device that air is carried out sterilization and deodorizing generally all is the device that utilizes ultraviolet ray to carry out sterilization and deodorizing.The device that utilizes ultraviolet ray to carry out sterilization and deodorizing comprises that utilization utilizes ultraviolet ray to carry out the device of sterilization merely, utilizes ultraviolet ray excited photocatalyst to carry out the device of sterilization, the device that utilizes ultraviolet generation ozone to carry out sterilization.
Simple device and the utilization ultraviolet ray that utilizes ultraviolet ray to carry out sterilization produces the device that ozone carries out sterilization, obtained extensive use at aspects such as various public places and table-ware disinfections.
The photocatalyst technology is also comparatively ripe now, and photocatalyst has arrived extensive use in purifying air.Photocatalyst is a kind of luminous energy to be converted into the material of chemical energy, utilizes chemical energy to carry out sterilization and deodorizing, reaches the purpose that purifies air.Photocatalyst itself does not consume in the use.People utilize the above-mentioned characteristic of photocatalyst to make air cleaning unit.
Being authorized the day for announcing is on April 2nd, 2008, application number is 200720068610.0, name is called the utility model patent of " nano-photon air cleaning unit ", a kind of air cleaning unit is disclosed, comprehensive utilization the ultraviolet ray of multiple wave band, rational in infrastructure, have good sterilization and deodorization functions.
Above ultraviolet radiation for sterilizing and disinfecting technology carries out sterilization when eliminating the oil smoke composition and technical foundation has been established in deodorizing.
Summary of the invention
The object of the present invention is to provide a kind of Zero discharge cooking fume purifier, have high temperature resistant, be difficult for to block, can operate as normal during the cleaning and filtering net, the effective advantage of kill bacteria and deodorizing.
Problem solved by the invention can realize by the following technical solutions:
Zero discharge cooking fume purifier comprises purifier carrier, filter, it is characterized in that, also comprises electrodes for removing dust, ultraviolet air cleaning unit; Described purifier carrier is a tubulose, and two ends are respectively equipped with air inlet and exhaust outlet; Described purifier carrier inside to exhaust outlet one end, is equipped with filter, ventilative electrodes for removing dust and ultraviolet air cleaning unit from air inlet one end successively.
After air enters the purifier carrier, at first pass through filter, oil droplet that the filtering volume is bigger and solid particle; Pass through electrodes for removing dust again, utilize the electrostatic precipitation principle, less oil droplet and the solid particle of adsorption volume under effect of electric field; Pass through ultraviolet air cleaning unit at last, kill airborne bacterium, germ and removing peculiar smell, air is discharged.
Said process thoroughly filters out airborne big or small oil droplet and solid particle by screen pack and electrostatic precipitation, kills airborne bacterium and removes peculiar smell by ultraviolet air cleaning unit, and the high-quality that has reached air purifies.
The side of described purifier carrier walls is provided with an opening, and opening part seals with dismountable baffle plate; Described opening inboard is provided with draw-in groove, and filter and electrodes for removing dust are plugged on purifier carrier the inside by described draw-in groove.
Adopt the method for pegging graft that filter and electrodes for removing dust are fixed on purifier carrier the inside, open dismountable baffle plate, can take out filter and electrodes for removing dust, be convenient to it is cleaned.
The described opening inboard draw-in groove that is provided with two groups of filters that are used to peg graft side by side, two filters are plugged on purifier carrier the inside side by side.
Adopt two filters obviously than adopting a filter that better dust removal by filtration effect is arranged, take off wherein one when filter need clean or keep in repair in addition and clean, little to the influence of complete equipment.
Described filter has screen pack, and screen pack is block, constitutes by wire is staggered in a jumble.
Above-mentioned screen pack is block, constitutes by wire is staggered in a jumble, at first because be to be made by metal material, has characteristics high temperature resistant, that the life-span is long; Constitute by wire is staggered in a jumble, unlike original screen pack, have filtering holes, therefore be not easy to occur blocking.
Described ultraviolet air cleaning unit can be the simple ultraviolet air cleaning unit that utilizes ultraviolet ray to carry out sterilization, can be to utilize ultraviolet ray excited photocatalyst to carry out the ultraviolet air cleaning unit of sterilization, can be to utilize ultraviolet ray to produce the ultraviolet air cleaning unit that ozone carries out sterilization, can be the ultraviolet air cleaning unit of the multiple ultraviolet sterilization mode of comprehensive utilization.
In sum the present invention have high temperature resistant, be difficult for to block, clean or can operate as normal during the maintenance filter, the effective advantage of kill bacteria and deodorizing.
